TY - JOUR T1 - Application of AUVs in the exploration for and characterization of arc volcano seafloor hydrothermal systems AN - 1769967916; 2016-017747 AB - The application of Autonomous Underwater Vehicles (AUVs) in the search for, and characterization of, seafloor hydrothermal systems associated with arc volcanoes has provided important information at a scale relevant to the study of these systems. That is, 1-2 m resolution bathymetric mapping of the seafloor, when combined with high-resolution magnetic and water column measurements, enables the discharge of hydrothermal vent fluids to be coupled with geological and structural features, and inferred upflow zones. Optimum altitude for the AUVs is nearly equal 70 m ensuring high resolution coverage of the area, maximum exposure to hydrothermal venting, and efficiency of survey. The Brothers caldera and Clark cone volcanoes of the Kermadec arc have been surveyed by ABE and Sentry. At Brothers, bathymetric mapping shows complex features on the caldera walls including embayments, ridges extending orthogonal to the walls and the location of a dominant ring fault. Water column measurements made by light scattering, temperature, ORP and pH sensors confirmed the location of the known vent fields on the NW caldera wall and atop the two cones, and discovered a new field on the West caldera wall. Evidence for diffuse discharge was also seen on the rim of the NW caldera wall; conversely, there was little evidence for discharge over an inferred ancient vent site on the SE caldera wall. Magnetic measurements show a strong correlation between the boundaries of vent fields determined by water column measurements and observed from manned submersible and towed camera surveys, and donut-shaped zones of magnetic "lows" that are focused along ring faults. A magnetic low was also observed to cover the SE caldera site. Similar surveys over the NW edifice of Clark volcano also show a strong correlation between active hydrothermal venting and magnetic lows. Here, the survey revealed a pattern resembling Swiss cheese of magnetic lows, indicating more widespread permeability. Moreover, the magnetic survey showed evidence for a highly magnetized ring structure nearly equal 350 m below the volcano summit considered to represent a buried (by continued growth of the cone) caldera rim. Zones of magnetic lows located inside the inferred caldera that are not associated with present-day venting are consistent with an earlier stage of hydrothermal activity.

The InterRidge Vents Database lists only 3 confirmed (visualized) and 35 inferred (plume evidence) active sites along the nearly equal 21,000 km of CARs. Here, we report on a multi-year effort to locate and characterize hydrothermal activity on two 1st-order segments of the Australian-Antarctic Ridge that are perhaps more isolated from other known vent fields than any other vent site on the Mid-Ocean Ridge. KR1 is a 300-km-long segment near 62 degrees S/159 degrees E, and KR2 a 90-km-long segment near 60 degrees S/152.5 degrees E. We used profiles collected by Miniature Autonomous Plume Recorders (MAPRs) on rock corers in March and December of 2011 to survey each segment, and an intensive CTD survey in Jan/Feb 2013 to pinpoint sites and sample plumes on KR1. Optical and oxidation-reduction potential (ORP, aka Eh) anomalies indicate multiple active sites on both segments. Seven profiles on KR2 found 3 sites, each separated by nearly equal 25 km. Forty profiles on KR1 identified 13 sites, some within a few km of each other. The densest site concentration on KR1 occurred along a relatively inflated, 90-km-long section near the segment center. CTD tows covered 20 km of the eastern, most inflated portion of this area, finding two 6-km-long zones centered near 158.6 degrees E and 158.8 degrees E with multiple plume anomalies. Three ORP anomalies within 50 m of the seafloor indicate precise venting locations. We call this area the Mujin "Misty Harbor" vent field. Vent frequency sharply decreases away from Mujin. (super 3) He/heat ratios determined from 20 plume samples in the Mujin field were mostly <0.015 fM/J, indicative of chronic venting, but 3 samples, 0.021-0.034 fM/J, are ratios typical of a recent eruption. The spatial density of hydrothermal activity along KR1 and KR2 is similar to other intermediate-rate spreading ridges. We calculate the plume incidence (ph) along KR1 and KR2 as the mean of the fraction of MAPR casts detecting a plume in each 2nd-order segment. For all 6 segments, ph=0.37+ or -0.25, consistent with the prediction of 0.33 from the global trend of ph for a spreading rate of 68 mm/yr.

Here, we demonstrate that the packing density (Phi f) of compacted rigid aggregates is independent of spatial scale for systems under weak compaction, a regime that includes small solar system bodies. The Phi f of rigid aggregated structures across 6 orders of magnitude were measured using nanoscale spherical soot aerosol composed of aggregates with nearly equal 17 nm monomeric subunits and aggregates made from uniform monomeric 6 mm spherical subunits at the macroscale. We find Phi f = 0.36 + or - 0.02 at both the nano- and macroscale. These values are remarkably similar to qf observed for comet nuclei and measured values of other rigid aggregated systems across a wide variety of spatial and formative conditions. We present a packing model that incorporates the aggregate morphology and show that Phi f is independent of both monomer and aggregate size. These observations suggest that qf of rigid aggregates is independent of spatial dimension across varied formative conditions ranging from interstellar space to pharmaceutical manufacturing.

In the present contribution, we present the geochemistry of the hydrothermal plumes over the KR1, an AAR segment at 159 degrees E and 62 degrees S. In 2011, we collected 48 Miniature Autonomous Plume Recorder profiles, measuring optical back scatter and oxidation-reduction potential, and identified the area between 158.5 and 159 degrees E as the densest concentration of active hydrothermal sites. In order to further characterize the chemistry of the hydrothermal plumes over the area, named "Mujin", we conducted intensive vertical and tow-yo CTD casts in 2013. The maximum concentrations of the chemical tracers (super 3) He, CH (sub 4) , H (sub 2) , and dissolved Mn, were 7.47 fmol/kg, 19.6 nmol/kg, 8.8 nmol/kg, 94.3 nmol/L, respectively. The CH (sub 4) / (super 3) He (1 -10) and CH (sub 4) /Mn (0.01 - 0.2) ratios were significantly lower than many ultra-mafic hosted systems, which are often found in slow spreading ridges. The lower ratios are consistent with a basaltic-hosted system, typical of the intermediate spreading rate of 6.8 cm/yr of KR1. Additionally, some of the plume samples collected around 158.6 and 158.8 degrees E exhibited slightly higher ratios of H (sub 2) / (super 3) He than the others. Assuming that H (sub 2) is produced from the reduction of water by reduced iron compounds in the rock, the higher ratios suggest that those plumes are supported by a younger hydrothermal system, which may have experienced a recent eruption.

Open, or deep-ocean instruments are especially valuable in that they provide high precision observations, have a lower level of background noise than coastal counterparts, and are free from the distortion effects of coastal bathymetry and topography. We take advantage of these observations to investigate the prevalence of a negative wave (trough) leading the first positive wave observed by the more than 40 deep-ocean bottom pressure recorders and approximately 200 tide gauges that were in operation over this time period. We consider two major events: 2010 Chile, and 2011 Tohoku, and present negative trough signatures for 2012 Haida Gwaii and 2014 northern Chile. Careful investigation of tsunami arrival at each deep-ocean site highlights the role filtering techniques may play in masking phenomenon such as the leading negative wave that is the basis of this study. The main focus of this investigation is to characterize the scale and repeatability of the phenomenon rather than provide a definitive explanation as to the cause.

It is completely web-based and it's supporting components can be hosted in the cloud. This application core functionality, designed and built into Tweb from the initial release, is the capability to selectively share tsunami event information for authorized users. These users, typically state-level Emergency Managers, can log into Tweb to view tsunami event products in a web browser. As a tsunami event evolves the forecasted information could change. Tweb allows a privileged user (tsunami forecaster) to change what the information view-only user can see for a specific event. This "live document" capability is important as it allows users, dependant on tsunami wave arrival and inundation information for their emergency management role, to always see the latest information the tsunami experts have the most confidence in. Components of this application are now being considered for use by NOAA's Tsunami Warning Centers (TWCs). This presentation will illustrate the integration with the SIFT and Tweb Forecasting tool, show how this information is rendered in the View-Only client, and demonstrate how the user will always see the latest iteration of the shared tsunami event information.

ComMIT is a desktop application providing a powerful and fully functional, yet easy-to use graphical user interface to the NCTR-developed MOST tsunami forecasting model. ComMIT is a self-contained downloadable application available from NCTR for use by qualified and novice modelers alike. We have recently added functionality that allows ComMIT to retrieve the prefered model solution for tsunami events from the Tweb Web Service. A ComMIT user with access to high resolution coastal bathymetry can generate detailed inundation models for real or synthetic events for their areas of interest. Then with the push of a button, the ComMIT user can upload their model results to Tweb where a community of tsunami modelers and forecasters can see these model results displayed in Tweb, along with other operational and contributed inundation forecast models. Besides the crowdsourcing aspect of tsunami modeling that will allow tsunami forecasters to get inundation model inputs from areas they normally would not consider, these contributed flooding models could provide forecasters with an early model solution verification capability by allowing model result comparisons with local tide gauge data in areas where operational models have not been developed. In addition, with the proper training this tool is very useful for education and as a vehicle for community tsunami hazard assessment. We will illustrate the model solution and results interchange capabilities now possible with these two applications.

A tsunami was triggered by this earthquake and caused flooding along the northern coast of Chile. Time series of water surface elevations were recorded at tide gauges and DART (Deep-ocean Assessment and Report of Tsunamis) tsunami sensors in the Pacific Ocean. By comparing the wave spectra of the Iquique event with those of other historical events in this region, we notice the former are characterized with significantly higher energy concentration in high-frequency wave modes. This is an indicator of strong frequency dispersion effects, which can quickly reduce the amplitudes of the leading waves in open ocean. These effects are demonstrated through numerical simulations with a weakly dispersive Boussinesq model. The oceanic propagation of this tsunami is also simulated with MOST (Method of Splitting Tsunami), the numerical simulating tool of NO-AA's tsunami forecast system, termed SIFT (Short-term Inundation Forecasting of Tsunamis). Though MOST is based on the nonlinear shallow-water theory, the numerical dispersion introduced by its finite difference scheme can be manipulated to compensate the neglected physical frequency dispersion, and makes it applicable to dispersive wave propagations.

This presentation will focus on the impacts of the 2004 and 2011 tsunamis and new societal expectations accompanying enhanced funding for tsunami research. A list of scientific products, including tsunami hazard maps, tsunami energy scale, real-time tsunami flooding estimates, and real-time current velocities in harbors will be presented to illustrate society's need for relevant, easy to understand tsunami information. Appropriate use of these tsunami scientific products will be presented to demonstrate greater tsunami resilience for tsunami threatened coastlines. Finally, a scientific infrastructure is proposed to ensure that these products are both scientifically sound and represent today's best practices to protect the scientific integrity of the products as well as the safety of coastal residents.

During 1990-2000, the International Decade for Natural Disaster Reduction, the tsunami scientific community took on the difficult task of developing the modeling capability that would provide accuracy needed for long-term tsunami forecast-tsunami hazard maps. After exhaustive field, laboratory and modeling efforts by the international scientific community, the modeling capability has been achieved with accuracy deemed sufficient for operational use. Several real-time model forecast tools started to be used at TWCs in the US and Japan. In parallel, the observational component of tsunami warning systems had been improving, including updated existing seismic and coastal sea-level stations array. New early detection and measurement system (DART) has been developed specifically for tsunami forecast applications. The 2004 Sumatra tsunami has triggered the efforts of intensive implementation of science results into operational tsunami warning capabilities. At present, several tsunami forecast systems, based on various modeling and detection capabilities, are operational. Since 2004, over 40 tsunamis, including the 2011 Japanese tsunami, provided real-time tests for the tsunami forecast system capabilities. Preliminary assessment of tsunami forecast performance will be presented based on the analysis of the U.S. operational tsunami inundation forecast. Assessing forecast performance is important to evaluate the needs for improvement and further research. Baseline of the tsunami forecast skills has now been established and will be presented based on the data from the tsunamis during the decade. Future improvements and future challenges will also be discussed.

As SLRrel increases mean sea level (MSL), there is naturally an increase in tidal datum elevations and increased frequency and duration of inundation during extreme events both spatially and temporally above fixed elevation thresholds. Another consequence of SLRrel is the increase in lesser extremes such as occasional minor coastal flooding experienced during high tide. Impacts from recurrent coastal flooding include overwhelmed stormwater drainage capacity, frequent road closures, and general deterioration and corrosion of infrastructure not designed to withstand frequent inundation or salt-water exposure. In our study, we show that water level exceedances above the elevation threshold for "minor" coastal flooding (nuisance level) impacts established locally by the National Weather Service (NWS) have been increasing over time. More importantly, event frequencies are accelerating at many U.S. East and Gulf Coast gauges and others will follow regardless of whether there is an acceleration of SLRrel. A regional pattern shows that greater event-rate acceleration occurs as the height between high tide and a location's nuisance flood threshold elevation decreases. We argue that increased frequency of nuisance flooding is one of the most sensible indicators of climate related sea level rise. We describe intra-annual nuisance flood patterns and related physical forcing patterns to enhance public awareness and recognition of this growing problem.

Seldom does landsliding of one type transition abruptly into the other, however, and seldom are the consequences more severe than at a site near Oso, Washington, where more than 40 fatalities resulted from a high-speed, long-runout landslide on 22 March 2014. Our interpretations of seismic data inversions and eyewitness accounts indicate that the Oso event began gradually, with remobilization of old landslide deposits that were unusually wet due to months of exceptional precipitation. For about 50 s, relatively slow downslope motion of these deposits withdrew support from a bluff above them, and then the bluff collapsed abruptly. This collapse radiated strong broadband seismic energy and rapidly loaded the old landslide material downslope. We infer that this rapid loading of previously dilated landslide debris caused contractive deformation, widespread liquefaction, and runaway acceleration. The resulting debris avalanche flow (DAF) had a volume of 8X10 (super 6) m (super 3) and a fahrboschung (H/L ratio) of 0.106, making it exceptionally mobile for a landslide of its size. The leading edge of the Oso DAF may have gained mobility by entraining water as it displaced the adjacent Stillaguamish River and by liquefying wet floodplain sediments as it overran them, and it formed distal deposits that resembled those of many wood-freighted debris flows. The transition from relatively slow landslide motion (which had occurred intermittently for decades at the Oso site) to high-speed motion and long runout appears to have been very sensitive to contingencies. Our simulations of the Oso event using a new numerical model (D-Claw) show that small differences in water-saturated porosity (n) were sufficient to cause divergent landslide behaviors. In a case with n=0.38, D-Claw predicts runaway liquefaction and high-speed runout much like that observed at Oso, and in a case with n=0.36, it predicts much slower landsliding that ceases after only about 100 m of motion. This behavioral bifurcation has fundamental physical importance as well as large ramifications for assessment of landslide hazards.

Based on input received from a broad group of marine scientists and resource managers, over 100,000 square kilometers of seafloor and associated water column were systematically explored using advanced mapping sonars. 39 ROV dives were conducted, leading to new discoveries that will further our understanding of biologic, geologic, and underwater-cultural heritage secrets hidden within the oceans. In the Atlantic, season highlights include completion of a multi-year submarine canyons mapping effort of the continental shelf break from North Carolina to the U.S.-Canada maritime border;new information on the ephemerality of recently discovered and geographically extensive cold water seeps; and continued exploration of the New England Seamount chain; and mapping of two potential historically significant World War II wreck sites. In the Gulf of Mexico, season highlights include completion of a multi-year mapping effort of the West Florida Escarpment providing new insight into submarine landslides and detachment zones; the discovery of at least two asphalt volcanoes, or 'tar lilies'; range extensions of deep-sea corals; discovery of two potential new species of crinoids; identification of at least 300 potential cold water seeps; and ROV exploration of three historically significant 19th century shipwrecks. In both regions, high-resolution mapping led to new insight into the geological context in which deep sea corals develop, while ROV dives provided valuable observations of deep sea coral habitats and their associated organisms, and chemosynthetic habitats. All mapping and ROV data is freely available to the public in usable data formats and maintained in national geophysical and oceanographic data archives.

Glacial Isostatic Adjustment (GIA) is responsible for vertical movement throughout the Great Lakes region. Fairport Harbor is also experiencing vertical movement due to salt mining, so the nearby water level gauge operated by the National Oceanic and Atmospheric Administration (NOAA) is affected by both GIA and mining. NOAA's National Geodetic Survey (NGS) defines and maintains the National Spatial Reference System (NSRS). The NSRS includes a network of permanently marked points; a consistent, accurate, and up-to-date national shoreline; a network of Continuously Operating Reference Stations (CORS) which supports three-dimensional positioning activities; and a set of accurate models describing dynamic, geophysical processes that affect spatial measurements. The NSRS provides the spatial reference foundation for transportation, mapping, charting and a multitude of scientific and engineering applications. Fundamental elements of geodetic infrastructure include GPS CORS (3-D), water level and tide gauges (height) and a system of vertical bench marks (height). When two or more of these elements converge they may provide an independent determination of position and vertical stability as is the case here at the Fairport Harbor water level gauge. Analysis of GPS, leveling and water level data reveal that this gauge is subsiding at about 2-3 mm/year, independent of the effects of GIA. Analysis of data from the nearby OHLA GPS CORS shows it subsiding at about 4 mm/yr, four times faster than expected due to GIA alone. A long history of salt mine activity in the area is known to geologists but it came as a surprise to other scientists.

Until recently, seeps were manually detected when viewing water-column backscatter returns in post-processing software. This manual procedure is time consuming and subjective. To examine this subjectivity, the NOAA Office of Exploration and Research conducted a quality control test using data collected during an expedition aboard the NOAA Ship Okeanos Explorer in the Gulf of Mexico from March to April, 2014. Water-column backscatter data was post-processed underway in FMMidwater and seep coordinates were manually geopicked from the beam fan. Ten percent of the original survey lines were independently re-processed using the same manual detection methods but with a different observer. Results show that manual seep selection can be highly variable between two different individuals. To help reduce this subjectivity and time required to manually detect seeps, QPS, Inc. developed a Feature Detection Tool for FMMidwater that uses an algorithm developed by the University of New Hampshire Center for Coastal and Ocean Mapping. To test the tool, the 10% subset of survey lines were run through the Feature Detection Tool using default settings, and the automatically detected seeps were compared with the manual geopicks. Not surprisingly, initial results show there can be variability between manual and algorithm seeps. Scrutiny of the automatic picks shows that the tool identified 60% of the seeps detected, and verified, by the independent manually-detecting observers. 32% of the seeps identified manually were missed by the tool, but 8% additional seeps were identified by the algorithm that had been missed through manual detection. The automatic detection showed several false positives, requiring manual intervention, but at a significantly lower level of effort than manual scrutinization of the raw data.

Accurate Global Navigation Satellite System (GNSS) positioning is a specialized skill involving expertise and fraught with accuracy-compromising nuances. With the goal of providing a robust and high accuracy positioning tool and enhanced access to the United States' National Spatial Reference System (NSRS), the nation's fundamental positioning infrastructure, NOAA's National Geodetic Survey (NGS) developed the Online Positioning User Service (OPUS). OPUS is a free Web utility for processing user-submitted GNSS observations and producing geodetic coordinates referenced to both NSRS and a global reference frame. Relying on NGS' national network of GNSS Continuously Operating Reference Stations (CORS), OPUS is a powerful and user-friendly tool for production and scientific research. OPUS is widely used in geomatics professions and holds great, yet not fully tapped, potential for research geoscientists requiring accurate positional information. OPUS became operational in 2002 as a single point processing tool for multi-hour GPS occupations (OPUS-Static). Its capability has since evolved, adding the ability to process short (15 minutes) sessions (OPUS-RapidStatic) and to provide a solution sharing option. All OPUS variations have proven to be popular, with typical monthly submissions now numbering 40,000. In 2014, NGS released a network version of OPUS, OPUS-Projects, the focus of this discussion. Although other versions of OPUS process a single GNSS occupation per submission, OPUS-Projects offers rigorous geodetic network analysis and processing capability by assembling and processing GNSS observations collected over time and at multiple locations. Least squares geodetic network adjustment of included observations results in an optimal set of station coordinates, including their uncertainties and graphical statistical plots, derived from user-submitted observation data, CORS observation data and coordinates, satellite ephemerides, and models. Users have the ability to configure the processing, including tropospheric modeling, definition of observation sessions, network design, adjustment constraints, station descriptive information, and integration with passive geodetic control.

AGU, 95(21), 27 May 2014) illustrated a map of the seafloor in the Malaysia Airlines Flight MH370 search area. This map showed a bathymetric model that is constructed from a combination of available ship soundings and depths estimated from satellite altimetry. They noted that available depth measurements covered only 5% of their study region, and that very few of these measurements were collected using modern multibeam and navigation systems. Recently the MH370 search has been expanded along the "7th Arc" to encompass newly prioritized underwater search areas identified in an Australian Transport Safety Bureau report (AE-2014-054, 26 June 2014). While the new "Priority" search area is within the Eos article Fig. 1, the new "Wide" search area extends beyond the region evaluated in Eos. Additionally, multibeam data that were not incorporated in the bathymetric model have been made available to us after the Eos article was published. This presentation will update and extend the study published in Eos. We will present illustrations of the expanded region, sounding coverage, and tectonic features that are associated with steep topographic slopes. Our results include comparisons of multibeam survey depths and bathymetric model depths. The standard deviation of the differences is 182 m, with the greatest differences (exceeding 1000 m) over steep topographic slopes, and the smallest over low-relief ocean floor. This is consistent with differences found by Smith and Sandwell (JGR, 99(B11), 1994) between soundings and bathymetric predictions from altimetry. Such depth differences are common where bathymetric model constraints are sparse, which is typical of many of the world's oceans.

We investigate two different scales of UAS platforms for monitoring coastal processes along the central Texas Gulf coast. Firstly, the eBee is a small-scale UAS weighing approximately 0.7 kg designed for localized mapping. The imaging payload consists of a hand held RGB digital camera and NIR digital camera, both with 16.1 megapixel resolutions. The system can map up to 10 square kilometers on a single flight and is capable of acquiring imagery down to 1.5 cm ground sample distance. The eBee is configured with a GPS receiver, altitude sensor, gyroscope and a radio transmitter enabling autonomous flight. The system has a certificate of authorization (COA) from the FAA to fly over the Ward Island campus of Texas A&M University-Corpus Christi (TAMUCC). The campus has an engineered beach, called University Beach, located along Corpus Christi Bay. A set of groins and detached breakwaters were built in an effort to protect the beach from erosive wave action. The eBee is being applied to periodically survey the beach. Through Structure from Motion (SfM) techniques, eBee-derived image sequences are post-processed to extract 3D topography and measure volumetric change. Additionally, when water clarity suffices, this approach enables the extraction of shallow-water bathymetry. Results on the utilization of the eBee to monitor beach morphodynamics will be presented including a comparison of derived estimates to RTK GPS and airborne lidar. Secondly, the RS-16 UAS has a 4 m wingspan and 11 kg sensor payload. The system is remotely piloted and has a flight endurance of 12 to 16 hours making it suitable for regional scale coastal mapping. The imaging payload consists of a multispectral sensor suite measuring in the visible, thermal IR, and ultraviolet ranges of the spectrum. The RS-16 is being used to conduct surveys along the shoreline of North Padre Island, which is a high wind energy and wave-dominated barrier island system. Results on the utilization of the RS-16 to study alongshore variability in shoreline dynamics and surf zone processes, such as wave runup, will be presented.

Insights from Saral and Cryosat AN - 1752576689; 2016-003273 AB - Satellite altimeter data collected along densely spaced ground tracks can map the marine gravity field, revealing the tectonic fabric of the sea floor. This application requires high accuracy of the along-track derivative of sea surface height over distances shorter than 80 km, and so is very sensitive to the instrument's range precision and any factors that produce short-scale along-track correlation of range measurement errors. To date the altimeters that have collected data over a dense network of ground tracks all acquired their largest data sets in Ku band and employing conventional (incoherent) processing. Two new altimeters go beyond conventional Ku instruments. SARAL AltiKa operates as an incoherent altimeter at Ka-band, and CryoSat collects some Ku-band data in a SAR mode to permit coherent processing for aperture synthesis and delay-Doppler calculations. The along-track range noise correlation characteristics of each of these new measurements are different from what has been seen in previous altimeters. SARAL AltiKa has a lower noise floor than pre-Cryosat Ku-band instruments and its noise spectrum shows decorrelation at different wavelengths, in partial agreement with theoretical work on speckle noise decorrelation over homogeneous surfaces. This improved noise performance results in demonstrable improvement in the resolution of geoid anomalies over small seamounts. Retracking of Cryosat's SAR mode multi-looked waveform yields a decorrelation of range errors unlike that found in conventional instruments, such that it doesn't require two-pass retracking to get the best geoid slope resolution. This is due mainly to the waveform's shape, which yields partial derivatives with respect to geophysical parameter estimates that are more nearly orthogonal than in conventional Ku-band Brown model waveforms. Further understanding of the limits on range precision in these instruments will require understanding of the heterogeneities in reflecting surfaces that are not yet accounted for in standard retracking methods, how these heterogeneities produce errors in range, and how these errors are serially correlated along-track. Some insight may be had by comparing measurements over ocean surfaces with measurements over heterogeneous scenes on land and in coastal zones or leads in sea ice.

Today the GEBCO community consists of an international group of experts in seafloor mapping who develop a range of data sets and data products with the aim of providing the most authoritative publicly-available bathymetric data sets for the world's oceans. We are also training a new generation of seafloor mappers through the Nippon Foundation/GEBCO Training Programme. GEBCO operates under the joint auspices of the Intergovernmental Oceanographic Commission (IOC) of UNESCO and the International Hydrographic Organization (IHO). Our range of products includes: A global Digital Terrain Model (DTM)--modelling the shape of the seafloor in the form of a periodically-updated 30 arc-second interval grid A gazetteer of undersea feature names GEBCO Cook Book-- information on topics related to building bathymetric grids Web services GEBCO world map GEBCO Digital Atlas--a collection of GEBCO's data sets and viewing software. Recognising the importance of local expertise when building a bathymetric grid, GEBCO's latest 30 arc-second interval DTM, GEBCO (sub 2014) , (due for release in Fall 2014) has benefited from contributions from many regional mapping projects such as the International Bathymetric Charts of the Arctic Ocean (IBCAO) and Southern Ocean (IBCSO); the Baltic Sea Bathymetry Database and EMODnet for European waters. Through the Sub-Committee on Regional Undersea Mapping, GEBCO is aiming to build on and extend its collaboration with regional mapping groups to continually improve its global bathymetric model.

Heavy rainfall-triggered landslides are often associated with flash flood events and cause additional loss of life and property. Therefore, it is important to understand the linkage and interaction between flash flood events and landslides. It is also pertinent to build a robust coupled flash flood and landslide disaster early warning system for disaster preparedness and hazard management. In this study, we built a coupled flash flood and landslide disaster early warning system, which is aimed for operational use by the US National Weather Service, based on an existing ensemble framework by extending the model ensemble and coupling a set of distributed hydrologic models, the Coupled Routing and Excess STorage (CREST) model and the SACramento Soil Moisture Accounting (SAC-SMA) model, with two physically based landslide prediction models, the SLope-Infiltration-Distributed Equilibrium (SLIDE) model and the Transient Rainfall Infiltration and Grid-Based Regional Slope-Stability (TRIGRS) model. We tested this prototype warning system by conducting multi-year simulations driven by the Multi-Radar Multi-Sensor (MRMS) rainfall estimates at selected basins across the United States. We then comprehensively evaluated the predictive capabilities of this system against observed and reported flood and landslides events. Our results show that the system is generally capable of making accurate predictions of flash flood and landslide events in terms of their locations and time of occurrence. The recently developed ensemble framework also enables us to quantify the uncertainty of the predictions and the probabilities of anticipated disaster events.

Pacific Tsunami Warning Center (PTWC) scientists had predicted they would have this ability (Becker et al., 2012) with their RIFT forecast model (Wang et al., 2009) by using rapidly-determined W-phase centroid-moment tensor earthquake focal mechanisms as tsunami sources in the RIFT model (Wang et al., 2012). PTWC then acquired its own YouTube channel in 2013 for its outreach efforts that showed animations of historic tsunamis (Becker et al., 2013), but could also be a platform for sharing future tsunami animations. The 8.2 Mw earthquake of 1 April 2014 prompted PTWC to issue official warnings for a dangerous tsunami in Chile, Peru and Ecuador. PTWC ended these warnings five hours later, then issued its new tsunami marine hazard product (i.e., no coastal evacuations) for the State of Hawaii. With the international warning canceled but with a domestic hazard still present PTWC generated a forecast model animation and uploaded it to its YouTube channel six hours before the arrival of the first waves in Hawaii. PTWC also gave copies of this animation to television reporters who in turn passed it on to their national broadcast networks. PTWC then created a version for NOAA's Science on a Sphere system so it could be shown on these exhibits as the tsunami was still crossing the Pacific Ocean. While it is difficult to determine how many people saw this animation since local, national, and international news networks showed it in their broadcasts, PTWC's YouTube channel provides some statistics. As of 1 August 2014 this animation has garnered more than 650,000 views. Previous animations, typically released during significant anniversaries, rarely get more than 10,000 views, and even then only when external websites share them. Clearly there is a high demand for a tsunami graphic that shows both the speed and the severity of a tsunami before it reaches impacted coastlines, similar to how radar and satellite images show the advancement of storms. Though this animation showed that most of the tsunami waves would not be dangerous, future publication of these animations will require additional outreach and education to avoid any unnecessary alarm. https://www.youtube.com/user/PacificTWC JF - American Geophysical Union Fall Meeting AU - Becker, N C AU - Wang, D AU - McCreery, Charles AU - Weinstein, Stuart AU - Ward, B AU - Anonymous Y1 - 2014/12// PY - 2014 DA - December 2014 SP - Abstract NH11C EP - 07 PB - American Geophysical Union, Washington, DC VL - 2014 KW - 22:Environmental geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1739086752?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=American+Geophysical+Union+Fall+Meeting&rft.atitle=The+first+real-time+tsunami+animation&rft.au=Becker%2C+N+C%3BWang%2C+D%3BMcCreery%2C+Charles%3BWeinstein%2C+Stuart%3BWard%2C+B%3BAnonymous&rft.aulast=Becker&rft.aufirst=N&rft.date=2014-12-01&rft.volume=2014&rft.issue=&rft.spage=&rft.isbn=&rft.btitle=&rft.title=American+Geophysical+Union+Fall+Meeting&rft.issn=&rft_id=info:doi/ LA - English DB - GeoRef N1 - Conference title - American Geophysical Union 2014 fall meeting N1 - Copyright - GeoRef, Copyright 2015, American Geosciences Institute.

At the U.S. National Tsunami Warning Center (NTWC), the model is mainly used in a pre-computed fashion. That is, results for hundreds of hypothetical events are computed before alerts, and are accessed and calibrated with observations during tsunamis to immediately produce forecasts. ATFM uses the non-linear, depth-averaged, shallow-water equations of motion with multiply nested grids in two-way communications between domains of each parent-child pair as waves get closer to coastal waters. Even with the pre-computation the task becomes non-trivial as sub-grid resolution gets finer. Currently, the finest resolution Digital Elevation Models (DEM) used by ATFM are 1/3 arc-seconds. With a serial code, large or multiple areas of very high resolution can produce run-times that are unrealistic even in a pre-computed approach. One way to increase the model performance is code parallelization used in conjunction with a multi-processor computing environment. NTWC developers have undertaken an ATFM code-parallelization effort to streamline the creation of the pre-computed database of results with the long term aim of tsunami forecasts from source to high resolution shoreline grids in real time. Parallelization will also permit timely regeneration of the forecast model database with new DEMs; and, will make possible future inclusion of new physics such as the non-hydrostatic treatment of tsunami propagation. The purpose of our presentation is to elaborate on the parallelization approach and to show the compute speed increase on various multi-processor systems.

Instrumental and paleoclimate data indicate that hydroclimate varies more strongly at multidecadal to millennial time frequencies than at interannual frequencies. Multi-millennial control runs in both ESM2Mb and ESM2G reproduce strong temperature variance at multi-century to millennial scales in the Northern Hemisphere (20 degrees N-90 degrees N). However, ESM2Mb does not reproduce strong multi-decadal to millennial precipitation variance in the Northern Hemisphere, whereas ESM2G captures strong multi-century scale precipitation variance in the Northern Hemisphere. In the tropics (20 degrees S-20 degrees N), these models do not reproduce strong multi-decadal to millennial precipitation and temperature variance as compared to interannual variance. Our findings suggest that the latest IPCC AR5 climate models are likely to underestimate the background risk of multidecadal hydroclimatic variability (drought). Different representations of ocean processes in ESM2Mb and ESM2G can change the variance of hydroclimatic variability on interannual to millennial time scales.

Post event assessments of global coastline vulnerability highlighted the Caribbean as a region of high hazard and risk and that it was poorly monitored. Nearly 100 tsunamis have been reported for the Caribbean region and Adjacent Regions in the past 500 years and continue to pose a threat for its nations, coastal areas along the Gulf of Mexico, and the Atlantic seaboard of North and South America. Significant efforts to improve monitoring capabilities have been undertaken since this time including an expansion of the United States Geological Survey (USGS) Global Seismographic Network (GSN) (McNamara et al., 2006) and establishment of the United Nations Educational, Scientific and Cultural Organization (UNESCO) Intergovernmental Coordination Group (ICG) for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS). The minimum performance standards it recommended for initial earthquake locations include: 1) Earthquake detection within 1 minute, 2) Minimum magnitude threshold = M4.5, and 3) Initial hypocenter error of <30 km. In this study, we assess current compliance with performance standards and model improvements in earthquake and tsunami monitoring capabilities in the Caribbean region since the first meeting of the UNESCO ICG-Caribe EWS in 2006. The three measures of network capability modeled in this study are: 1) minimum Mw detection threshold; 2) P-wave detection time of an automatic processing system and; 3) theoretical earthquake location uncertainty. By modeling three measures of seismic network capability, we can optimize the distribution of ICG-Caribe EWS seismic stations and select an international network that will be contributed from existing real-time broadband national networks in the region. Sea level monitoring improvements both offshore and along the coast will also be addressed. With the support of Member States and other countries and organizations it has been possible to significantly expand the sea level network thus reducing the amount of time it now takes to verify tsunamis.

Three hours later, while the weather was calm, a sudden runup of water along the New Jersey and New England coasts was witnessed despite no nearby seismic activity. Post-event analysis revealed that a rare meteotsunami impacted the East Coast of the United States. The strong pressure jump associated with the storms generated an ocean wave that became amplified when the speed of the storms reached the speed of the wave, creating resonance. The wave approached the Mid-Atlantic shelf break and reflected back, explaining the time lag between the passing storms and the incoming wave. The National Water Level Observing Network (NWLON) stations maintained by the National Oceanic and Atmospheric Administration (NOAA) National Ocean Service (NOS) Center for Operational Oceanographic Products and Services (CO-OPS) measured strong water level oscillations at several stations along the eastern seaboard. The detided one-minute data show the tsunami signal with maximum amplitudes ranging from 0.16 m at Nantucket Island, MA to 0.61 m. at Newport, RI. The Narragansett Bay stations captured the meteotsunami wave propagating northward and diminishing towards the innermost part of the Bay. The Atlantic City, NJ station captured the 3.2-mb pressure jump in the six-minute barometer data from the passing storms as well as the incoming wave that hit three hours later with a maximum amplitude of 0.47 m. Along the U.S. coast, harbor shape and orientation contributed to the strength of the tsunami wave, and some stations that were in shadowed areas did not measure a strong signal despite being in an area of measurable impact. Meteotsunamis pose a threat to the U.S. coastline, and without high-resolution observations and models these events cannot be quantitatively forecasted. NOAA does not currently have an operational warning system but the June 2013 meteotsunami provides an excellent case study for identifying setup conditions and timing of an impact from a reflected wave.

Ports are usually designed to protect boats and docks against sudden vertical water fluctuations. Tsunami currents however are often ignored - current monitoring is usually not quantitative - in the design of harbor modifications. Damage from tsunami currents in ports has occurred in several recent tsunamis (Sea of Japan, 1983; Chile, 1960, 2010; Tohoku, 2011). Significant tsunami currents (>2 m/sec) often occur without substantial wave amplitudes (<1-2 meters). Because tsunami amplitudes are used as the basis to determine event "significance", the hazard from potentially strong currents may be overlooked. In order to evaluate the impact of anthropogenic effects on tsunami impact at ports, we examine the history of man-made modifications made to San Diego Bay since the late nineteenth century. Digital elevation models were created based on historic nautical charts of 1892, 1935, 1945 and at present. Tsunami simulations were conducted based on two distant events (1960 Chile and 2011 Tohoku) and two hypothetical severe local cases (San Clemente fault bend and Coronado Canyon landslide). The distant events provide historical comparisons with the model while the local events are based on offshore geology and tectonic activity. Most of the changes in San Diego Bay have included dredging, enlargement of the North Island/Coronado, widening of the Silver Strand, and creation of new marinas by enhancing already existing dunes or filling and creating breakwaters. Those changes mostly occurred during the first half of the 20th century. Post-1965 the bay has sustained a similar appearance to the bathymetry/topography we know today. Early harbor configurations showed strong currents in the narrow channel between Point Loma and North Island/Coronado while overtopping of the narrow Silver Strand to the south occurred. The modern configuration finds increased currents at the harbor entrance and between Coronado and downtown San Diego, where the channel has been narrowed, while widening of the Silver Strand appears to reduce overtopping. Since the change in tsunami impact is not a linear function of modifications in the harbor, we will discuss on how these man-made modifications introduce or relocate strong currents and inundation in the bay.

This paper describes the Redwood Coast Tsunami Work Group (RCTWG), an organization formed in 1996 to address the tsunami threat from both near and far sources. It includes representatives from government agencies, public, private and volunteer organizations, academic institutions, and individuals interested in working to reduce tsunami risk. The geographic isolation and absence of scientific agencies such as the USGS and CGS in the region, and relatively frequent occurrence of both earthquakes and tsunami events has created a unique role for the RCTWG, with activities ranging from basic research to policy and education and outreach programs. Regional interest in tsunami issues began in the early 1990s when there was relatively little interest in tsunamis elsewhere in the state. As a result, the group pioneered tsunami messaging and outreach programs. Beginning in 2008, the RCTWG has partnered with the National Weather Service and the California Office of Emergency Services in conducting the annual "live code" tsunami communications tests, the only area outside of Alaska to do so. In 2009, the RCTWG joined with the Southern California Earthquake Alliance and the Bay Area Earthquake Alliance to form the Earthquake Country Alliance to promote a coordinated and consistent approach to both earthquake and tsunami preparedness throughout the state. The RCTWG has produced and promoted a variety of preparedness projects including hazard mapping and sign placement, an annual "Earthquake - Tsunami Room" at County Fairs, public service announcements and print material, assisting in TsunamiReady community recognition, and facilitating numerous multi-agency, multidiscipline coordinated exercises, and community evacuation drills. Nine assessment surveys from 1993 to 2013 have tracked preparedness actions and personal awareness of tsunami hazards. Over the twenty-year period covered by the surveys, respondents aware of a local tsunami hazard increased from 51 to 90 percent and awareness of the Cascadia subduction zone increased from 16 to 60 percent.

Indeed, previous research suggests speleothems are sensitive to water vapor transport, and experiments currently underway are evaluating the role of Greenlandic vapor in setting the isotopic record of the ice sheet. The recent and rapid spread of commercial vapor isotopic analyzers-based on cavity-enhanced near-infrared laser absorption spectroscopy-is creating unparalleled opportunities to elucidate which climatic factors control the vapor isotopic composition globally. This presentation describes both an exciting application of this new technology and relevant limitations imposed by measurement uncertainties associated with long-term field deployments. Using three years of continuous water vapor isotope ratio observations from Hawaii's Mauna Loa Observatory-one of the longest records of its kind-we evaluate the influence of large-scale dynamics and cloud microphysical processes in establishing the isotopic composition of water vapor during strong convective activity. Despite the fact that vapor isotope ratios tend to decrease with latitude, greater enrichment in Mauna Loa vapor is associated with a westward retraction of the jet stream, which funnels Asiatic outflow southward, while greater depletion is associated with southwesterly low-level flow. Differences in precipitation efficiency-which are verified by differences in aerosol concentration and total scattering-cause this apparent discrepancy. These results suggest local cloud and precipitation processes are more influential than airmass origin in setting the isotope ratios observed during these strong convective events. The length of the Mauna Loa record, meanwhile, presents a unique opportunity to evaluate long-term stability of biases associated with laser-based isotopic analyzers and to discuss calibration strategies best suited for monitoring programs designed to evaluate transient relationships between isotopic and climatic variability.

The Dust Bowl in the 1930s was the largest natural catastrophe in the North America history, caused by extended drought and poor land management. Although the severity and duration of the 1930s drought was exceptional, reconstructed paleo-climatic records show that the central U.S. plains have experienced severe droughts about once or twice a century over the past 400 years. Dust record is hence an integral component of the national climate assessment (NCA). This work presents our recent efforts to develop a climate-quality indicator of local windblown dust storms in the U.S. For the arid and semi-arid regions of the western United States, we have developed a novel approach to identify local windblown dust events through routine ambient aerosol monitoring (Tong et al., 2012). This work uses the dust identification algorithm to develop a dust storm dataset (dust indicator), and rely on satellite dust detection and model dust prediction as independent data sources to test, cross-check and validate the dust indicator. This work will extend our research capabilities to contribute developing new climate indicators that are especially aimed at needs of local environmental managers in the Southwestern communities.

Work through the International Civil Aviation Organization (ICAO) International Airways Volcano Watch Operations Group (IAVWOPSG) and International Airways Volcano Task Force (IAVTF) brought increased awareness and focus to this challenge. A VAAC Best Practices group was formed out of these larger meetings and focused on VAAC specific issues of importance. Collaboration was one of the topics under consideration. Some ideas and procedures for an effective, yet easy, method for the VAACs to collaborate have been discussed. Implementation has been mainly on a VAAC to VAAC basis, however a more consolidated process needs to be developed and agreed upon between all VAACs in order to successfully move toward harmonization. Collaboration procedures and tools are being considered. The National Weather Service (NWS) Alaska Region has been looking at collaborative software to help the VAACs identify the presence of ash and forecast the plume both in the horizontal and vertical. Having an interactive graphical interface within the forecast operation may help to ensure consistency across VAAC boundaries. Existing chat software within NWS is being investigated to allow Tokyo and Anchorage VAAC to "chat" about forecast issues in real time. This capability is being tested through scenarios. The Anchorage and Tokyo VAACs participated in a series of meetings in Tokyo in March 2014. Collaboration was a major topic of discussion. This paper will outline some of the efforts being undertaken between the Anchorage and Tokyo VAACs as a result of these meetings and subsequent dialogue.

Such forecasts would be an official NOAA statement of the expected thermal state of permafrost ALT in Alaska and would require: (1) long-term climate outlooks, (2) a permafrost model, (3) detailed specification of local spatial and vertical controls upon soil thermal state, (4) high-resolution vertical measurements of that thermal state, and (5) demonstration of forecast skill in pilot studies. Pilot efforts should focus on oil pipelines where the cost can be justified. With skillful forecasts, engineers could reduce costs of monitoring and repair as well as ecosystem damage by positioning equipment to more rapidly respond to predicted disruptions.

The survey took place in Iowa along U.S Route 30. The survey line is approximately 200 miles long (325 km), extending from Denison, IA to Cedar Rapids, IA. There are over 200 official survey bench marks. A leveling survey was performed, conforming to 1st order, class II specifications. A GPS survey was performed using 24 to 48 hour occupations. Absolute gravity, relative gravity, and gravity gradient measurements were also collected during the survey. In addition, deflections of the vertical were acquired at 200 eccentric survey benchmarks using the Compact Digital Astrometric Camera (CODIAC) camera. This paper presents the preliminary results of the survey, including the accuracy analysis of the leveling data, GPS ellipsoidal heights, and the deflections of the vertical which serves as an independent data set in addition to the GPS/leveling implied geoid heights.

These virtual communities offer readily sustainable opportunities to facilitate communication across a wide range of cultural lines and socioeconomic levels thereby broadening participation and inclusivity in STEM. Established in 2003, the Minorities Striving and Pursuing Higher Degrees of Success (MS PHD'S) in Earth System Science Professional Development Program has successfully used virtual community tools such as a listserv, community forum, social media, and VoIP technologies, to extend the face-to-face activities of the program and support the advancement of URM students and early career scientists in STEM. The use of multiple facets of virtual community by MS PHD'S participants supports and encourages "real life" interactions and mentorship, facilitates networking and professional development, and maintains continuity of shared networks. The program is now in its ninth cohort and supports 213 participants. To date, 54 participants have completed their PhD and another 61 are currently enrolled in doctoral programs.

We presented the likely inundation areas, current velocities in key ports and harbors, physical damage and repair costs, economic consequences, environmental impacts, social vulnerability, emergency management, and policy implications for California associated with the scenario tsunami. The intended users were those responsible for making mitigation decisions before and those who need to make rapid decisions during future tsunamis. The Tsunami Scenario process is being evaluated by the University of Colorado's Natural Hazards Center; this is the first time that a USGS scenario of this scale has been formally and systematically evaluated by an external party. The SAFRR Tsunami Scenario was publicly introduced in September, 2013, through a series of regional workshops in California that brought together emergency managers, maritime authorities, first responders, elected officials and staffers, the business sector, state agencies, local media, scientific partners, and special districts such as utilities (http://pubs.usgs.gov/of/2013/1170/). In March, 2014, NOAA's annual tsunami warning exercise, PACIFEX, was based on the SAFRR Tsunami Scenario. Many groups conducted exercises associated with PACIFEX including the State of Washington and several counties in California. San Francisco had the most comprehensive exercise with a 3-day functional exercise based on the SAFRR Tsunami Scenario. In addition, the National Institutes of Health ran an exercise at the Ports of Los Angeles and Long Beach in April, 2014, building on the Tsunami Scenario, focusing on the recovery phase and adding a refinery fire. The benefits and lessons learned include: 1) stimulating dialogue among practitioners to solve problems; 2) seeing groups add extra components to their exercises that best address their specific concerns; 3) providing groups with information packaged specifically for them; 4) recognizing the value of having scenario developers personally present the scenario to user groups and 5) having the SAFRR work applied to support ongoing activities by and future directions of the California state tsunami program.

These new technologies are anticipated to improve measurement accuracies such that: dynamic relative gravimeters would be accurate to < 1 milliGal; static relative gravimeters would be accurate to < 1 microGal; and static absolute gravimeters would be accurate to < 10 nanoGal. With instruments that are sensitive to signals several magnitudes smaller than currently possible, the question arises about which dynamic effects of the natural and manmade environments will affect these more sensitive instruments. This talk will attempt to summarize the current state of knowledge on forces that produce dynamic gravity effects and dynamic forces that could affect the ability to make gravity measurements with new instrumentation at nanoGal levels. Some examples of processes that produce dynamic gravity signals include: earth and ocean tides, fluid withdrawal in the subsurface, atmospheric density changes, earthquakes, and glacial isostatic adjustment. A separate set of dynamic environmental factors affect the ability to make accurate gravity measurements, including: movement of humans or other mass near sensitive instruments, vibrations, vehicle motion for kinematic measurements, environmental forcing on field absolute gravimeters, etc. These effects will be considered for not only their magnitudes, but also their spatial scales (from continental to within the immediate vicinity of the gravity instrument) and their uncertainties. The goal of this work is to provide guidance on which dynamic gravity effects are well known and which are not, as well as what corrections may needed for future gravity measurements.

Normally, low-pass filters (Childers et al 1999, Forsberg et al 2000, Kwon and Jekeli 2000, Hwang et al 2006) are applied to smooth or remove the high frequency "noise" - even though some of the high frequency component is not necessarily noise. This is especially true for aerogravity surveys such as those from the Gravity for the Redefinition of the American Vertical Datum (GRAV-D) project. These gravity survey flights have a spatial resolution of 10 km between tracks but higher resolution along track. The along track resolution is improved due to the lower flight height (6.1 km), equipment sensitivity, and improved modeling of potential errors. Additionally, these surveys suffer from a loss of signal power due to the increased flight elevation. Hence, application of a low-pass filter removes possible signal sensed in the along-track direction that might otherwise prove useful for various geophysical and geodetic applications. Some cutting-edge developments in Wavelets and Artificial Neural Networks had been successfully applied for obtaining improved results (Li 2008 and 2011, Liang and Liu 2013). However, a clearer and fundamental understanding of the error characteristics will further improve the quality of the gravity estimates out of these gravimetric systems. Here, instead of using any predefined basis function or any a priori model, the idea of Factor Analysis is first employed to try to extract the underlying factors of the noises in the systems. Real data sets collected by both land vehicle and aircraft will be processed as the examples.

As part of the multi-agency Guanica Bay Watershed Project, a study was undertaken to establish baseline levels of terrigenous sedimentation reaching reefs adjacent to the Guanica Bay watershed as well as establish spatial and temporal patterns in its delivery. To characterize and quantify sedimentation patterns, sediment traps were established at nine reef sites occurring along an approximately 14 km stretch of coastline centered on the outlet of the bay. Sites were located at shallow reefs within 2 km of the shore at depths of approximately 10 m. Two additional sites were located at the mouth of the Rio Loco where it empties into Guanica Bay and at the mouth of the bay where it opens into adjacent coastal waters. Traps were collected monthly from August 2009 through July 2012 to determine both the amount of sediment accumulation (mg cm-2 day-1) and its composition. Composition is expressed in terms of relative amounts of calcium carbonate (in situ production), organic material and terrigenous material. Average trap accumulation rates among the reef sites ranged from approximately 3 to 28 mg cm-2 day-1. Average percent terrigenous material within reef accumulation ranged from approximately 20% to 30%. While trap accumulation rates are highly variable on both spatial and temporal scales, the composition of sediments and relative amount of terrigenous material is fairly uniform. Similar temporal patterns in accumulation rates among the sites without corresponding changes in composition of sediments point to resuspension of bottom sediments by wave action as a primary driver of sedimentary dynamics at these reefs. Sites closest to Guanica Bay display the highest degree of terrigenous influence in terms of trap accumulation rates and percent terrigenous material, which is consistent with Guanica Bay serving as a local source of terrigenous material to coastal waters. However, the lack of east-west trends relative to the bay mouth in either trap accumulation rates or percent terrigenous material indicates that Guanica Bay is not the sole or necessarily primary source of terrigenous materials reaching nearshore reefs.

Particulate Al distributions reflect large sedimentary inputs from the Ganges-Brahmaputra river system into the Bay of Bengal as well as ice melt and shelf inputs near the Antarctic continent with lower concentrations in surface waters from deposition of aerosol dust. Elevated particulate Fe is evident at depth (>300m) downstream of the Kerguelen plateau, suggesting input of particulate Fe from plateau sediments may fuel surface productivity in this region. Cu, Ni, and Pb are elevated in surface waters centered around 40S, suggesting an anthropogenic signature potentially influenced by local atmospheric deposition or advection into the interior of the basin by the South Indian Ocean Current. In the south Indian Ocean, particulate matter composition reflects high biological production as evidenced by elevated particulate P concentrations in surface waters, with a sharp delineation apparent between high particulate Ca concentrations within the 'great calcite belt' (30-55S) and high particulate Si and Zn concentrations in the Indian sector of the Southern Ocean associated with diatom productivity. We will also present particulate trace metal data from CLIVAR zonal transect I5 between South Africa and Australia (May-May 2009) that is currently being analyzed.

Reflectance spectra decreased dramatically across all wavelengths up to 1400 nm with increasing black carbon and the reflectance spectra did not converge at infrared wavelengths. At the most contaminated site with rBC of 345 ppb and DBC of 75 ppb, absolute reflectance was much lower than previously published results with values between 10 and 20% in blue wavelengths. This indicates the potential impact of BC on natural long-term contaminated snow spectra subject to melt and refreezing and the possibility to serve as a natural end member for global remote sensing studies. These results are also significant because there is increasing pressure being put on Arctic communities to increase mining exploration. Additionally, diminishing sea-ice resulting in increased shipping traffic will also contribute to BC impacts in the Arctic.

At Axial Seamount, nearly all thermophilic methanogens are Methanothermococcus and Methanocaldococcus species, making this site amenable to modeling through pure culture laboratory experiments coupled with field studies. Based on field microcosm incubations with 1.2 mM, 20 mu M, or no hydrogen, the growth of methanogens at 55 degrees C and 80 degrees C is limited primarily by temperature and hydrogen availability, with ammonium amendment showing no consistent effect on total methane output. The Arrhenius constants for methane production by Methanocaldococcus jannaschii (optimum 82 degrees C) and Methanothermococcus thermolithotrophicus (optimum 65 degrees C) were determined in pure culture bottle experiments. The Monod constants for hydrogen concentration were measured by growing both organisms in a 2-liter chemostat at two dilution rates; 55 degrees C, 65 degrees C and 82 degrees C; and variable hydrogen concentrations. M. jannaschii showed higher ks and Vmax constants than M. thermolithotrophicus. In the field, hydrogen and methane concentrations in hydrothermal end-member and low-temperature diffuse fluids were measured, and the concentrations of methanogens that grow at 55 degrees C and 80 degrees C in diffuse fluids were determined using most-probable-number estimates. Methane concentration anomalies in diffuse fluids relative to end-member hydrothermal concentrations and methanogen cell concentrations are being used to constrain a 1-D reactive transport model using the laboratory-determined Arrhenius and Monod constants for methane production by these organisms. By varying flow path length and subseafloor cell concentrations in the model, our goal is to determine solutions for the potential depth of the subseafloor biosphere coupled with the amount of methanogenic biomass it contains.

The NOAA Deep Sea Coral Research and Technology Program's National Database for Deep-Sea Corals and Sponges is a comprehensive resource for georeferenced data on these organisms in U.S. waters. The National Database currently includes more than 220,000 deep-sea coral records representing approximately 880 unique species. Database records from museum archives, commercial and scientific bycatch, and from journal publications provide baseline information with relatively coarse spatial resolution dating back as far as 1842. These data are complemented by modern, in-situ submersible observations with high spatial resolution, from surveys conducted by NOAA and NOAA partners. Management of high volumes of modern high-resolution observational data can be challenging. NOAA is working with our data partners to incorporate this occurrence data into the National Database, along with images and associated information related to geoposition, time, biology, taxonomy, environment, provenance, and accuracy. NOAA is also working to link associated datasets collected by our program's research, to properly archive them to the NOAA National Data Centers, to build a robust metadata record, and to establish a standard protocol to simplify the process. Access to the National Database is provided through an online mapping portal. The map displays point based records from the database. Records can be refined by taxon, region, time, and depth. The queries and extent used to view the map can also be used to download subsets of the database. The database, map, and website is already in use by NOAA, regional fishery management councils, and regional ocean planning bodies, but we envision it as a model that can expand to accommodate data on a global scale.

Paleo-proxy records of the warming at the end of the last ice age, however, suggests a different outcome, namely a better ventilated and oxygenated deep ocean with global warming. Here we use a four thousand year global warming simulation from a comprehensive Earth System Model (GFDL ESM2M) to show that this conundrum is a consequence of different rates of warming and that the deep ocean is actually better ventilated and oxygenated in a future warmer equilibrated climate consistent with paleo-proxy records. The enhanced deep ocean ventilation in the Southern Ocean occurs in spite of increased positive surface buoyancy fluxes and a constancy of the Southern Hemisphere westerly winds--circumstances that would otherwise be expected to lead to a reduction in deep ocean ventilation. This ventilation recovery occurs through a global scale interaction of the Atlantic Meridional Overturning Circulation undergoing a multi-centennial recovery after an initial century of transient decrease and transports salinity-rich waters inform the subtropical surface ocean to the Southern Ocean interior on multi-century timescales. The subsequent upwelling of salinity-rich waters in the Southern Ocean strips away the freshwater cap that maintains vertical stability and increases open ocean convection and the formation of Antarctic Bottom Waters. As a result, the global ocean oxygen content and the nutrient supply from the deep ocean to the surface are higher in a warmer ocean. The implications for past and future changes in ocean heat and carbon storage will be discussed.

The latest forecasts even estimate an enhancement of 56% in total natural gas production due to increased development of shale gas, tight gas and offshore natural gas resources from 2012 to 2040 with the largest contribution from shale formations [US EIA: Annual Energy Outlook 2014]. During the field intensive 'Energy and Environment--Uintah Basin Winter Ozone Study (UBWOS)', measurements of volatile organic compounds (VOCs) were made using proton-transfer-reactions mass spectrometry (PTR-MS) at the ground site Horse Pool and using a mobile laboratory in the Uintah Basin, Utah, which is a region well known for intense fossil fuel production. A reworked gas well in the Red Wash fields was sampled regularly within two weeks performing mobile laboratory measurements downwind of the well site. The well had been recently hydraulically refractured at that time and waste water was collected into an open flow-back pond. Very high mixing ratios of aromatic hydrocarbons (C6-C13) up to the ppm range were observed coming from condensate and flow-back reservoirs. The measurements are used to determine sources of specific VOC emissions originating from the different parts of the well site and mass spectra are used to classify the air composition in contrast to samples taken at the Horse Pool field site and crude oil samples from South Louisiana. Enhancement ratios and time series of measured peak values for aromatics showed no clear trend, which indicates changes in emissions with operations at the site.

Attribution of methane to these different source sectors has proven difficult, as evidenced by persistent disagreement between the annual emissions estimated from atmospheric observations (top-down) and from inventories (bottom-up). Given the rapidly changing natural gas infrastructure in North America, and the implications of associated rapid changes in emissions of methane for climate, it is crucial we improve our ability to quantify and understand current and future methane emissions. Here, we present evidence that continuous in-situ airborne observations of ethane, which is a tracer for fossil fuel emissions, are a new and useful tool for attribution of methane emissions to specific source sectors. Additionally, with these new airborne observations we present the first tightly constrained ethane emissions estimates of oil and gas production fields using the well-known mass balance method. The ratios of ethane-to-methane (C2H6:CH4) of specific methane emissions sources were studied over regions of high oil and gas production from the Barnett, TX and Bakken, ND shale plays, using continuous (1 Hz frequency) airborne ethane measurements paired with simultaneous methane measurements. Despite the complex mixture of sources in the Barnett region, the methane emissions were well-characterized by distinct C2H6:CH4 relationships indicative of a high-ethane fossil fuel source (e.g., "wet" gas), a low-ethane fossil fuel source (e.g., "dry" gas), and an ethane-free, or microbial source. The defined set of C2H6:CH4 that characterized the emissions input to the atmosphere was used in conjunction with the total ethane and methane fluxes to place bounds on the fraction of methane emissions attributable to each source. Additionally, substantial ethane fluxes from the Barnett and Bakken regions were observed (1% to 10% of estimated national ethane emissions), and emissions of these magnitudes may significantly impact regional atmospheric chemistry and air quality by influencing production of tropospheric ozone.

Although natural gas combustion emits less carbon dioxide per energy produced than other fossil fuels, this climate benefit may be offset by the methane emitted to the atmosphere through leaks in the natural gas production and distribution infrastructure. To better understand the climate impacts of the oil and natural gas extracted from the Bakken shale play in North Dakota, we present airborne measurements of methane taken over this region aboard a NOAA Twin Otter aircraft during Spring 2014. Using the mass balance technique, we estimate methane emissions from the region with four flights intended for this purpose in May 2014. We further attribute these methane emissions to the oil and gas industry using measurements of ethane and other hydrocarbons aboard the Twin Otter.

It includes contributions not only from global eruptive volcanoes but also 8 near-equator degassing volcanoes. Emissions from Nyamuragira in November 2006 November and Grimsvotn in May 2011 that were missed in the IPCC-5 inventory are now included. Overall, in comparison with our new inventory, well-used AEROCOM eruptive volcanic emission has high biases by a factor of 4. With updated volcanic emission inventory, the volcanic sulfate distribution was simulated from global transport model GEOS-Chem, which shows consistent temporal evolution of zonally averaged sulfate AOD with the CALIOP AOD above 10 Km, and the modeled AOD capture every eruption volcano sulfate with similar magnitude as CALIOP counterpart. The 8 years average contribution from eruptive SO42- to total SO42- loading is approximately 10% over the most area, and is only significant for those eruptions above 10 km, with the maximum ratio of 30% along tropical area. Tropical degassing volcano SO42- barely reaches above 10 km, but is regionally dominate type of aerosols (60%+ in terms of mass in lower atmosphere) over Hawaii, and ocean area at northeast to Australia. The 8 years averaged global eruption volcano sulfate forcing (-0.09 Wm-2) is found to be slightly higher than reported by IPCC, and the tropical degassing sulfate forcing is estimated as -0.02 Wm-2. The global and monthly mean sulfate forcing efficiency to SO2 emission was calculated for 3 categories. For eruptive volcanoes sulfate the forcing efficiency is more than 5 times of the counterpart of the background (mostly anthropogenic) sulfate, and for the 8 tropical degassing volcanoes sulfate it is slight higher than the one for background sulfate. That indicates the injection height is an important factor to decide the volcano sulfate forcing efficiency. The updated volcanic database is available upon request.

The MT extends eastward from the Gorda Ridge spreading center, along the S side of the Gorda Plate, to the edge of the North American plate (NAP) and separates the Cascadia subduction zone to the north, from the modern SAF to the south. Between 127.5 degrees W and the shoreline, the MT and Mendocino Ridge (MR) align with the N side of the S-tilted Vizcaino structural block (VB), a remnant of NAP captured by the Pacific plate approximately 12 Ma, when the MT was 480 km S of its present location. The modern SAF bounds the NE-side of the VB. The SW side of the VB is bounded at the base of the continental slope by the proto-San Andreas fault (PSAF), where extinct remnants of the Pacific-Farallon ridge (PFR) interacted with the paleosubduction margin to form an incipient transform and several microplates, now part of the Pacific plate. Capture of the VB resulted from inboard breaking of the MT with a jump of the PSAF to the modern SAF. Dated approximately 20-12 Ma basaltic rocks from the MR between approximately 125 degrees -128 degrees W may be partly exhumed slab window underplating that formed beneath the VB during breakup of the PFR along the PSAF. High Fe and Ti relative to Mg in MR and KRT basalts, suggest eruption near ridge-transform intersections and perhaps, intratransform spreading.Onshore, high KRT relief aligns with the MR offshore. The KRT was assembled approximately 16-15 Ma (basalt K-Ar age; biostratigraphy); followed by its complex deformation and zeolitic metamorphism, indicating subduction to 5-8 km depth approximately 15-14 Ma and thermal metamorphism approximately 13.8 Ma (K-Ar age; vitrinite reflectance). The thermal overprint sets the KRT apart from adjacent accreted rocks. Similar MR and KRT age relations and ridge-transform intersection-related chemistry is consistent with collision of the PFR with the PSAF margin and development of a slab window beneath the VB and subducted KRT. This leads us to propose that the KRT is the NE corner of the VB, recently obducted onto the continental margin after northward translation with the Pacific plate.

Eruptions were observed at the summit (1.2 km water depth) during 5 ROV Jason dives in 2009 (the deepest erupting submarine volcano observed to date). Subsequent ROV and ship-based bathymetric mapping revealed that a pit crater formed and the summit eruption ceased in 2010, with roughly simultaneous eruptions along the SW rift zone. During the summit eruption, a combination of water depth, H2O-CO2-rich and high crystallinity magma, a split in the conduit to feed two vent sites, and waxing/waning magma supply led to a range of effusive/explosive eruption styles and volcanic deposit types. The 2-3 vent Hades cluster and the lone Prometheus vent had different eruption characteristics. Petrographic, petrologic and geochemical studies of erupted products indicate a change in magma composition in time and space over a period of 3.5 yrs, suggesting a small, open-system magma reservoir within the volcano. Prometheus (1174 m depth) produced mostly pyroclastic material during our observations (e.g., highly vesicular glowing fluidal ejecta that cooled in the water column and rounded recycled dense clasts), but sampling and 210Po radiometric dating show that several months prior pillowed lava flows, subsequently covered with cm-sized pyroclasts, had flowed >50 m from the vent. In contrast, vents at Hades (1200 m depth) cycled between lava production and vigorous degassing, 10-20 m high fire fountains and bursts of glowing lava-skinned bubbles, the products of which froze/broke in the water column, forming unstable cones of spatter and scoria near the vents. We hypothesize that bubbles collapse rather than form lava balloons because of skin brittleness (from high crystal content) and hydrostatic pressure. Clast settling times and patterns suggest >100m water column rise height for 10+ cm-sized fragments. Pillow flows were also observed to be issuing from the base of the Hades cones some 30-50 m below, and had traveled 100 m from the vent in the months before. This, plus hydrophone and water column data (Embley et al., G3, in review), and the occurrence of extensive deposits of young, glassy, identical composition cm-sized fragmental material 250 m from Hades suggest an earlier more vigorous phase of the eruption.

The remoteness of the volcano and the presence of several seamounts in the immediate area posed a challenge for constraining the source location of the eruption. Critical to honing in on the Ahyi area quickly were quantitative error estimates provided by the CTBTO on the backazimuth of hydroacoustic arrivals observed at Wake Island (IMS station H11). T-phases registered across the NMI seismic network at the rate of approximately 10 per hour until May 8 and were observed in hindsight at seismic stations on Guam and Chichijima. After May 8, sporadic T-phases were observed until May 17. Within days of the eruption onset, reports were received from NOAA research divers of hearing explosions underwater and through the hull on the ship while working on the SE coastline of Farallon de Pajaros (Uracas), a distance of 20 km NW of Ahyi. In the same area, the NOAA crew reported sighting mats of orange-yellow bubbles on the water surface and extending up to 1 km from the shoreline. Despite these observations, satellite images showed nothing unusual throughout the eruption. During mid-May, a later cruise leg on the NOAA ship Hi'ialakai that was previously scheduled in the Ahyi area was able to collect some additional data in response to the eruption. Preliminary multibeam sonar bathymetry and water-column CTD casts were obtained at Ahyi. Comparison between 2003 and 2014 bathymetry revealed that the minimum depth had changed from 60 m in 2003 to 75 m in 2014, and a new crater approximately 95 m deep had formed at the summit. Extending SSE from the crater was a new scoured-out landslide chute extending downslope to a depth of at least 2300 m. Up to 125 m of material had been removed from the head of the landslide chute and downslope deposits were up to 40 m thick. Significant particle plumes were detected at all three CTD casts of Ahyi volcano. Plumes with optical anomalies up to 0.4 NTU were found south and west of Ahyi at 100-175 m water depth, corresponding to the depth of the new summit crater. We plan to combine the extensive T-phase, hydroacoustic, CTD, and bathymetry data from Ahyi to characterize submarine volcanic processes and quantify the size and total radiated energy of the eruption.

The last eruption took place in 2001 but did not breach the sea surface. Focused and diffuse hydrothermal venting is taking place mainly within a small ( approximately 100X100 m) depression within the 300 m diameter crater of the volcano at depths of about 265 meters. Near the center of the depression clear fluids are being discharged from a focused mound-like vent at a maximum temperature of 180 degrees C with the simultaneous discharge of numerous bubble streams. The gas consists of 93-96% CO2 with trace amounts of methane and hydrogen. A sulfur component likely contributes 1-4% of the gas total. Gas flux measurements on individual bubble streams ranged from 10 to 100 kg of CO2 per day. Diffuse venting with temperatures 5 to 3 degrees C above ambient occurs throughout the depression and over large areas of the main crater. These zones are extensively colonized by reddish-yellow bacterial mats with the production of loose Fe-oxyhydroxides largely as a surface coating and in some cases, as fragile spires up to several meters in height. A high-resolution photo mosaic of the crater depression was constructed using the remotely operated vehicle Hercules on cruise NA039 of the E/V Nautilus. The image revealed prominent fluid flow patterns descending the sides of the depression towards the base. We speculate that the negatively buoyant fluid flow may be the result of second boiling of hydrothermal fluids at Kick'em Jenny generating a dense saline component that does not rise despite its elevated temperature. Increased density may also be the result of high dissolved CO2 content of the fluids, although we were not able to measure this directly. The low amount of sulphide mineralization on the crater floor suggests that deposition may be occurring mostly subsurface, in accord with models of second boiling mineralization from other hydrothermal vent systems.

Stable isotopes allow us to elucidate sources of methane due to the relatively distinct isotopic signatures from fossil fuel, biomass burning, and microbial sources. The Stable Isotope Laboratory at INSTAAR has been measuring delta 13C of CH4 from a subset of the NOAA Earth System Research Laboratory, Global Monitoring Division's Cooperative Air Sampling Network since 1998. Here we examine our 15 year record and show that since 2007, the global average atmospheric methane delta 13C value has decreased by 0.08 ppm. This is coincident with an increase in the growth rate of atmospheric methane after a period of near steady-state conditions from 1999 to 2006. The decrease in delta 13C of CH4 is evident at sites in the Arctic as well as in the northern mid-latitudes and the Southern Hemisphere. There has been no change in the inter-hemispheric difference of atmospheric methane isotopes, suggesting that the increased emissions do not originate predominantly in the Northern Hemisphere. Likewise, Miller-Tans plots, which examine regional, higher-frequency deviations from the background signal, show that sources of methane have become depleted in 13C since 2007 across latitudes, implicating stronger microbial emissions (such as those from wetlands). We use a 3-box model (Northern, Tropical and Southern) to test scenarios of increased methane sources and find that increased microbial emissions from the Northern Hemisphere and tropical regions are necessary to explain the isotopic shift. Furthermore, because there is not a change in the north-south gradient of delta 13C of CH4, and because fossil fuel emissions are primarily from northern latitudes, fossil fuel sources alone cannot explain the increase in methane emissions since 2007. This study shows the value of including stable isotopes in long-term, global observation networks to constrain sources of atmospheric methane.

This analysis shows that there is a very strong seasonal cycle in the CH4 mole fraction when winds are coming from the southern sector, which peaks in August and September each year with average enhancements of approximately 80 ppb. Despite many suggestions from other recent studies that CH4 emissions should be significantly enhanced in this region, our analysis indicates that emissions from the North Slope have not increased since the start of the measurement record. However, large enhancements in the CH4 mole fraction originating from the North Slope are correlated with increases in the mean air temperature coming from the same air masses, suggesting that with continued increases in North Slope surface temperatures, CH4 emissions from permafrost will increase in the North Slope as predicted.

As the Arctic permafrost destabilizes, labile carbon stored in the permafrost is subject to respiration and methanogenesis, producing greenhouse gases CO2 and CH4. Understanding the timing and rate of this release is paramount to our long-term understanding of the global climate structure, yet the remote location of the North Slope logistically precludes widespread tower measurements, necessitating airborne measurements. Presented are 12C and 13C CO2 concentration flux measurements taken via an aircraft at a height of 10-30 m during mid to late August 2013 from the north slope of Alaska. The data show different regimes for CO2 vs delta -13C over regions within a roughly 100 km box, indicating heterogenous landscape with differing dominant biological processes. The data are compared to CH4 measurements that were taken simultaneously, showing highly varying concentrations of CH4 with several different archetypical relationships to the total CO2 regimes. The relationship between CO2, delta -13C CO2, and CH4 concentrations provide further insight into the biological processes occurring in the melting Arctic permafrost. The data show that the dominant uptake and emission processes change by time of day and location. While the CO2 and isotopologue data alone indicates whether a region is dominant in respiration or photosynthesis, combining the data with CH4 measurements provides insight into the provenance of the CH4 as well as methanogenic biological pathways active on the North Slope, while mass balance between CH4, CO2 or delta -13C CO2 determines whether the methane signature is from methanogenesis, natural hydrocarbon seeps, or methane flaring. The data show few if any cases for which increases in methane concentrations are accompanied by a deviation in CO2 or delta -13C CO2 that would indicate incomplete methane flaring or natural seeps.

Human exposure, vulnerability, fatality and injury rates can be minimized by identifying and then mitigating the causative factors for human impacts. A database of flash flooding was used for statistical analysis of human impacts across the U.S. 21,549 flash flood events were analyzed during a 6-year period from October 2006 to 2012. Based on the information available in the database, physical parameters were introduced and then correlated to the reported human impacts. Probability density functions of the frequency of flash flood events and the PDF of occurrences weighted by the number of injuries and fatalities were used to describe the influence of each parameter. The factors that emerged as the most influential on human impacts are short flood durations, small catchment sizes in rural areas, vehicles, and nocturnal events with low visibility. Analyzing and correlating a diverse range of parameters to human impacts give us important insights into what contributes to fatalities and injuries and further raises questions on how to manage them.

However, the efficient retrieval of soil moisture for hydrological applications depends on optimally choosing the soil and vegetation parameters. The first stage of this work involves the evaluation of SMOS Level 2 products and then several approaches for soil moisture retrieval from SMOS brightness temperature are performed to estimate Soil Moisture Deficit (SMD). The most widely applied algorithm i.e. Single channel algorithm (SCA), based on tau -omega is used in this study for the soil moisture retrieval. In tau -omega , the soil moisture is retrieved using the Horizontal (H) polarisation following Hallikainen dielectric model, roughness parameters, Fresnel's equation and estimated Vegetation Optical Depth (tau ). The roughness parameters are empirically calibrated using the numerical optimization techniques. Further to explore the improvement in retrieval models, modifications have been incorporated in the algorithms with respect to the sources of the parameters, which include effective temperatures derived from the European Center for Medium-Range Weather Forecasts (ECMWF) downscaled using the Weather Research and Forecasting (WRF)-NOAH Land Surface Model and Moderate Resolution Imaging Spectroradiometer (MODIS) land surface temperature (LST) while the tau is derived from MODIS Leaf Area Index (LAI). All the evaluations are performed against SMD, which is estimated using the Probability Distributed Model following a careful calibration and validation integrated with sensitivity and uncertainty analysis. The performance obtained after all those changes indicate that SCA-H using WRF-NOAH LSM downscaled ECMWF LST produces an improved performance for SMD estimation at a catchment scale.

Hydrologic response indices have frequently been employed in contemporary regionalization research related to predictions in ungauged basins. In this study, we developed regionalization models using multiple linear regression and regression tree analysis to derive relationships between hydrologic response and watershed physical characteristics for 163 watersheds in the Great Lakes basin. These models provide an empirical means for simulating runoff in ungauged basins at a monthly time step without implementation of a rainfall-runoff model. For the dependent variable in these regression models, we used monthly runoff ratio as the indicator of hydrologic response and defined it at two temporal scales: (1) treating all monthly runoff ratios as individual observations, and (2) using the mean of these monthly runoff ratios for each watershed as a representative observation. Application of the models to 62 validation watersheds throughout the Great Lakes basin indicated that model simulations were far more sensitive to the temporal characterization of hydrologic response than to the type of regression technique employed, and that models conditioned on individual monthly runoff ratios (rather than long term mean values) performed better. This finding is important in light of the increased usage of hydrologic response indices in recent regionalization studies. Models using individual observations for the dependent variable generally simulated monthly runoff with reasonable skill in the validation watersheds (median Nash-Sutcliffe efficiency = 0.53, median R (super 2) = 0.66, median magnitude of the deviation of runoff volume = 13%). These results suggest the viability of empirical approaches to simulate runoff in ungauged basins. This finding is significant given the many regions of the world with sparse gauging networks and limited resources for gathering the field data required to calibrate rainfall-runoff models.

The technique is based on a novel extension of classical optimal linear estimation theory in which, in addition to error variance, Type-II conditional bias (CB) is explicitly minimized. When cast in the form of well-known kriging, the methodology yields a new kriging estimator, referred to as CB-penalized kriging (CBPK). CBPK, however, tends to yield negative estimates in areas of no or light precipitation. To address this, an extension of CBPK, referred to herein as extended conditional bias penalized kriging (ECBPK), has been developed which combines the CBPK estimate with a trivial estimate of zero precipitation. To evaluate ECBPK, we carried out real-world and synthetic experiments in which ECBPK and the gauge-only precipitation analysis procedure used in the NWS's Multisensor Precipitation Estimator (MPE) were compared for estimation of point precipitation and mean areal precipitation (MAP), respectively. The results indicate that ECBPK improves hourly gauge-only estimation of heavy-to-extreme precipitation significantly. The improvement is particularly large for estimation of MAP for a range of combinations of basin size and rain gauge network density. This paper describes the technique, summarizes the results and shares ideas for future research. Abstract Copyright (2014) Elsevier, B.V.

Here, we modify the Sacramento Soil Moisture Accounting (SAC-SMA) model to include a physically-based representation of the effects of freezing and thawing soil on the runoff generation process. This model is called the SAC-SMA Heat Transfer model (SAC-HT). The frozen ground physics are taken from the Noah land surface model which serves as the land surface component of several National Center for Environmental Prediction (NCEP) numerical weather prediction models. SAC-HT requires a boundary condition of the soil temperature at the bottom of the soil column (a climatic annual air temperature is typically used, and parameters derived from readily available soil texture data). A noteworthy feature of SAC-HT is that the frozen ground component needs no parameter calibration. SAC-HT was tested at 11 sites in the U.S. for soil temperature, one site in Russia for soil temperature and soil moisture, eight basins in the upper Midwest for the effects of frozen-ground on streamflow, and one location for frost depth. High correlation coefficients for simulated soil temperature at three depths at 11 stations were achieved. Multi-year simulations of soil moisture and soil temperature agreed very well at the Valdai, Russia test location. In eight basins affected by seasonally frozen soil in the upper Midwest, SAC-HT provided improved streamflow simulations compared to SAC-SMA when both models used a priori parameters. Further improvement was gained through calibration of the non-frozen ground a priori parameters. Frost depth computed by SAC-HT compared well with observed values in the Root River basin in Minnesota. Abstract Copyright (2014) Elsevier, B.V.

We found that the performance among these models when simulating total runoff to the lake varied relatively little, despite variability in model structure, spatial representation, input data, and calibration protocol. Relatively simple empirical, assimilative models, including the National Oceanic and Atmospheric Administration (NOAA) Great Lakes Environmental Research Laboratory (GLERL) area ratio-based model (ARM) and the United States Geological Survey (USGS) Analysis of Flows in Networks of CHannels (AFINCH) model, represent efficient and effective approaches to propagating discharge observations into basin-wide (including gaged and ungaged areas) runoff estimates, and may offer an opportunity to improve predictive models for simulating runoff to the Great Lakes. Additionally, the intercomparison revealed that the median of the simulations from non-assimilative models agrees well with assimilative models, suggesting that using a combination of different methodologies may be an appropriate approach for estimating runoff into the Great Lakes. We then applied one assimilative model (ARM) to the Lake Michigan basin and found that there was persistent reduction in the amount of precipitation that becomes runoff following 1998, corresponding to a period of persistent low Lake Michigan water levels. The study was conducted as a first phase of the Great Lakes Runoff Intercomparison Project, a regional binational collaboration that aims to systematically and rigorously assess a variety of models currently used (or that could readily be adapted) to simulate basin-scale runoff to the North American Laurentian Great Lakes.

Thus, a quantitative understanding of the frequency and locations where Asian dust is transported is necessary to improve global dust modeling for weather and climate predictions. This work presents a 10 year record (2002-2011) of dust along the U.S. West Coast estimated from the Interagency Monitoring of Protected Visual Environments network in an effort to characterize the seasonal cycle and interannual variability of Asian dust transport. In addition, observations of dust exported from East Asia were analyzed along with air mass trajectories and satellite and ground-based precipitation data to investigate seasonal variability of Asian dust transport. On average, Asian dust concentrations (0.08-0.60 mu g m (super -3) ) from ground-based observations were 1.7 times those of local dust (0.00-0.53 mu g m (super -3) ) and 23% (up to 44%) of fine particulate matter (particles with diameters < or =2.5 micrometers, or PM (sub 2.5) ) mass concentrations at high elevations in the spring. The maximum in springtime Asian dust on the U.S. West Coast was attributed to higher source concentrations (10.98-36.27 mu g m (super -3) ) and reduced potential for wet removal over the Pacific Ocean and U.S. West Coast. Although trans-Pacific transport was more favorable during the winter, minimum concentrations of Asian dust were observed on the U.S. West Coast (0.11 mu g m (super -3) ) due to a lower source influence and higher potential for wet removal during transport. Multiobservational approaches such as these should be taken into account when modeling transport of Asian dust to the western U.S. Abstract Copyright (2014), Copyright American Geophysical Union.

AN - 1566409826; 25181043 AB - Pacific herring embryos spawned in nearshore habitats may be exposed to toxic contaminants as they develop, from exogenous sources in spawning habitats and from maternal transfer. Determining baseline concentrations of these toxic contaminants is important for evaluating the health of this species, especially during this sensitive life stage. In this study we compared concentrations of polycyclic aromatic hydrocarbons, or PAHs, in naturally spawned herring embryos from five spawning areas across Puget Sound. The summed values of 31 PAH analytes (Σ31PAH) in early- to late-stage development embryos ranged from 1.1 to 140 ng/g, wet weight. Σ31PAH concentrations increased with development time in embryos from one spawning area where the greatest concentrations were observed, and the relative abundance of PAH chemicals in late-stage embryos was similar to those in nearby sediments, suggesting accumulation from local environmental sources. PAHs in both sediments and late-stage embryos appeared to exhibit a pyrogenic pattern. Although maternal transfer of PAHs appeared to be a negligible source to embryos in spawning areas with the greatest embryo PAH concentrations, maternal transfer may have been the dominant source in embryos from spawning areas where the lowest levels of embryo-PAHs occurred. Chronic embryo mortality has been reported in spawning habitats where we observed the greatest concentration of PAHs in embryos, and necrotic tissue in herring embryos from one such location was similar in description to phototoxic PAH necrosis reported elsewhere for embryonic zebrafish.

2014-102424 AB - Coral reefs exist in a delicate balance between calcium carbonate (CaCO (sub 3) ) production and CaCO (sub 3) loss. Ocean acidification (OA), the CO (sub 2) -driven decline in seawater pH and CaCO (sub 3) saturation state (Omega ), threatens to tip this balance by decreasing calcification and increasing erosion and dissolution. While multiple CO (sub 2) manipulation experiments show coral calcification declines under OA, the sensitivity of bioerosion to OA is less well understood. Previous work suggests that coral and coral-reef bioerosion increase with decreasing seawater Omega . However, in the surface ocean, Omega and nutrient concentrations often covary, making their relative influence difficult to resolve. Here, we exploit unique natural gradients in Omega and nutrients across the Pacific basin to quantify the impact of these factors, together and independently, on macrobioerosion rates of coral skeletons. Using an automated program to quantify macrobioerosion in three-dimensional computerized tomography (CT) scans of coral cores, we show that macrobioerosion rates of live Porites colonies in both low-nutrient (oligotrophic) and high-nutrient (>1 mu M nitrate) waters increase significantly as Omega decreases. However, the sensitivity of macrobioerosion to Omega is ten times greater under high-nutrient conditions. Our results demonstrate that OA (decreased Omega ) alone can increase coral macrobioerosion rates, but the interaction of OA with local stressors exacerbates its impact, accelerating a shift toward net CaCO (sub 3) removal from coral reefs.

To determine whether this modification affects total catch and deep-hooking rate of Black Sea Bass Centropristis striata in a recreational fishery off the coast of Florida, anglers were provided with standardized gear that included one appendaged and one nonappendaged hook. Both hook types were fished equally, and a greater number of Black Sea Bass were caught on appendaged hooks (n = 301) than on nonappendaged hooks (n = 221). There was no significant difference in the mean TL (P = 0.80) of jaw- or deep-hooked fish during the study. Logistic regression was applied to the data using anatomical hooking location as the dependent variable and angler, hook position, and hook type as categorical factors. Hook type was the only significant variable in the final model (P = 0.03) in which fewer fish were deep hooked on appendaged hooks (0.96%) than on nonappendaged hooks (2.11%). Our findings indicate appendaged hooks are capable of reducing deep hooking of Black Sea Bass without reducing catch rates or altering size composition of the catch.

Methodology and Simulation AN - 1676356465; PQ0001412803 AB - Geostatistical prediction can address two difficult issues in interpreting fishery-dependent catch per unit effort (CPUE): the lack of a sampling design and the need to fill spatial gaps. In this paper we demonstrate the spatial weighting properties of geostatistics for treating data collected without a sampling design or with a selection bias, two basic traits of fishery-dependent data. We then examine the bias and precision of geostatistical prediction of CPUE based on fishery-dependent data through simulation. We create data sets with known variograms, sample them with a preference for sites with high abundance, and then estimate variograms and CPUE as the geostatistical mean relative abundance. The variograms obtained from the simulated fishery samples correctly estimated the range but underestimated the sill, and the geostatistical mean substantially improved the estimation of CPUE over the arithmetic mean. Though the geostatistical mean still overestimated the true value, the error was primarily due to prediction into unsampled locations, where predictions revert toward the arithmetic mean. The geostatistical variance at a point, which is a function of spatial autocorrelation and the location of adjacent samples, provides a measure of uncertainty. This variance measures the degree to which predictions are derived from nearby data versus distant observations, which translates the spatial extent of extrapolation into probabilistic terms. In conjunction with conventional standardization methods that account for factors affecting catchability, geostatistical prediction provides an additional tool that reduces but does not eliminate biases inherent in fishery-dependent data and supports the need to predict CPUE in unsampled areas.

Application to a Scallop Fishery AN - 1676352121; PQ0001412804 AB - Fishery-dependent catch per unit effort (CPUE) comprises critical input for many stock assessments. Construction of CPUE indices usually employs some method of data standardization. However, conventional methods based on linear models do not effectively deal with the fact that samples are collected with a selection bias or with the problem of filling spatial gaps. Geostatistical interpolation methods can ameliorate some of the biases caused by both of these problems while remaining complementary to traditional linear model-based CPUE standardization. In this paper we present geostatistical estimates of sea scallop Placopecten magellanicus CPUE from tows recorded by onboard observers during an opening of Georges Bank Closed Area II in 1999. By selecting tows for which there was little prior effort (on the basis of accumulated effort measured by vessel monitoring systems), we obtained tows that reflected initial abundance as closely as possible. These tows were used to obtain a variogram which was used in geostatistical prediction of sea scallop CPUE. The kriged mean was substantially lower than the arithmetic sample mean, indicating that a geostatistical approach reduced the influence of repeated sampling in locations of extremely high CPUE and increased the weight of isolated observations in areas of low CPUE. The results produced a map that was qualitatively similar to that obtained from a preseason fishery-independent survey. Overall differences between the two approaches were driven by the extension of predictions into areas at the edges of spatial autocorrelation where kriging predictions approached the grand mean of the data set.

Landings from the two stocks are currently combined in U.S. assessments of the northern stock, but the stocks may be differentiated by their associated seawater habitats, which are predominantly characterized by different ranges of sea surface temperature. We compared the combined and temperature-differentiated landings of the two stocks in each country for the period 1993-2011, demonstrating how different attributions of the landings affected the estimated annual fishing fraction (F) for the northern stock. Using combined or stock-differentiated landings and assessed biomasses, we found that the current harvest control rule (HCR) for Pacific Sardine has not consistently maintained a total F below the U.S. target value because the "distribution" parameter (used to account for the northern stock's proportion in the U.S. Exclusive Economic Zone [EEZ]), has not adequately accounted for northern stock landings in Mexico and Canada. We propose a refinement to the HCR, giving explicit consideration to the summed landings in Mexico and Canada, to more optimally set the annual U.S. quota. The performance of our method was compared with (1) the values of F that would have been achieved during the federal management period (2000-2011) if the U.S. quotas had always been met and (2) the generally lower actual values of F that were calculated using the default HCR formulation (1993-2011). We demonstrate that application of our method would permit more U.S. fishing for Pacific Sardine when the northern stock is large and predominantly located in the U.S. EEZ and would curtail U.S. fishing when a large proportion of the stock is present and fished in the Mexican EEZ, Canadian EEZ, or both.

A total of 2,860 fish were radio-tagged in the lower basin during 2002-2004 and tracked upriver. Fish traveled to spawning areas throughout the basin, ranging from several hundred to over 3,000 km from the tagging site. Similar distribution patterns were observed across years, suggesting that the major components of the run were identified. Daily and seasonal composition estimates were calculated for the component stocks. The run was dominated by two regional components comprising over 70% of the return. Substantially fewer fish returned to other areas, ranging from 2% to 9% of the return, but their collective contribution was appreciable. Most regional components consisted of several principal stocks and a number of small, spatially isolated populations. Regional and stock composition estimates were similar across years even though differences in run abundance were reported, suggesting that the differences in abundance were not related to regional or stock-specific variability. Run timing was relatively compressed compared with that in rivers in the southern portion of the species' range. Most stocks passed through the lower river over a 6-week period, ranging in duration from 16 to 38 d. Run timing was similar for middle- and upper-basin stocks, limiting the use of timing information for management. The lower-basin stocks were primarily later-run fish. Although differences were observed, there was general agreement between our composition and timing estimates and those from other assessment projects within the basin, suggesting that the telemetry-based estimates provided a plausible approximation of the return. However, the short duration of the run, complex stock structure, and similar stock timing complicate management of Yukon River returns.

However, U.S. laws that govern the uses of ocean spaces present a challenging tangle of authorities and mandates that do not easily facilitate ecosystem-based policies. For over 30 years, U.S. marine fisheries management has been guided by eight Regional Fishery Management Councils. Working under the many laws that guide setting stewardship priorities for ocean ecosystems, councils provide the Federal Government with advice on fisheries harvest levels, fish habitat protections, and fishing community needs. Implementing EBM for any ocean ecosystem requires a careful examination of the laws and policy processes that affect human interaction with that ecosystem. This article explores the U.S. perspective on federal ecosystem-based fisheries management, its part in U.S. national ocean policy, and how fishery management councils might position themselves as both EBM policymakers and policy takers for ocean resource management.

Underwater explosive eruptions driven by magmatic gases were first witnessed there in 2004 and continued until at least 2010. During a March 2010 expedition, visual observations documented continuous but variable eruptive activity at multiple vents at approximately 560 m depth. Some vents released CO (sub 2) bubbles passively and continuously, while others released CO (sub 2) during stronger but intermittent explosive bursts. Plumes of CO (sub 2) bubbles in the water column over the volcano were imaged by an EM122 (12 kHz) multibeam sonar system. Throughout the 2010 expedition numerous passes were made over the eruptive vents with the ship to document the temporal variability of the bubble plumes and relate them to the eruptive activity on the seafloor, as recorded by an in situ hydrophone and visual observations. Analysis of the EM122 midwater data set shows: (1) bubble plumes were present on every pass over the summit and they rose 200-400 m above the vents but dissolved before they reached the ocean surface, (2) bubble plume deflection direction and distance correlate well with ocean current direction and velocity determined from the ship's acoustic doppler current profiler, (3) bubble plume heights and volumes were variable over time and correlate with eruptive intensity as measured by the in situ hydrophone. This study shows that midwater multibeam sonar data can be used to characterize the level of eruptive activity and its temporal variability at a shallow submarine volcano with robust CO (sub 2) output.

Methods and Results We evaluated and applied previously published qPCR assays to water samples (n = 1636) collected from Chesapeake Bay from 2007-2010 in conjunction with State water quality monitoring programmes. A variety of statistical techniques were used in concert to identify water quality parameters associated with V. vulnificus presence, abundance and virulence markers in the interest of developing strong predictive models for use in regional oceanographic modeling systems. A suite of models are provided to represent the best model fit and alternatives using environmental variables that allow them to be put to immediate use in current ecological forecasting efforts. Conclusions Environmental parameters such as temperature, salinity and turbidity are capable of accurately predicting abundance and distribution of V. vulnificus in Chesapeake Bay. Forcing these empirical models with output from ocean modeling systems allows for spatially explicit forecasts for up to 48 h in the future. Significance and Impact of the Study This study uses one of the largest data sets compiled to model Vibrio in an estuary, enhances our understanding of environmental correlates with abundance, distribution and presence of potentially virulent strains and offers a method to forecast these pathogens that may be replicated in other regions.

The analysis utilizes data from the Research Moored Array for African-Asian-Australian Monsoon Analysis and Prediction (RAMA) and the European Centre for Medium-Range Weather Forecasts-Ocean Reanalysis System 4 (ECMWF-ORAS4). Surface currents are characterized by semiannual eastward flowing Wyrtki jets along the equator in boreal spring and fall, forced by westerly monsoon transition winds. The fall jet intensifies during negative IOD (NIOD) events when westerlies are anomalously strong but significantly weakens during positive IOD (PIOD) events when westerlies are anomalously weak. As zonal wind stress weakens during PIOD events, sea surface height becomes unusually low in the eastern basin and high in the west, setting up an anomalous pressure force that drives increased eastward transport in the thermocline. Opposite tendencies are evident during NIOD events in response to intensified equatorial westerlies. Current transport adjustments to anomalous zonal wind forcing during IOD events extend into the following year, consistent with the cycling of equatorial wave energy around the basin. A surface layer mass budget calculation for the eastern sea surface temperature (SST) pole of the IOD indicates upwelling of approximately 2.9+ or -0.7 Sv during normal periods, increasing by 40-50% during PIOD events and reducing effectively to zero during NIOD events. IOD-related variations in Wyrtki jet and thermocline transports are major influences on these upwelling rates and associated water mass transformations, which vary consistently with SST changes.

The key objectives are to understand the Southwest Pacific Ocean circulation and the South Pacific Convergence Zone (SPCZ) dynamics, as well as their influence on regional and basin-scale climate patterns. South Pacific thermocline waters are transported in the westward flowing South Equatorial Current (SEC) toward Australia and Papua-New Guinea. On its way, the SEC encounters the numerous islands and straits of the Southwest Pacific and forms boundary currents and jets that eventually redistribute water to the equator and high latitudes. The transit in the Coral, Solomon, and Tasman Seas is of great importance to the climate system because changes in either the temperature or the amount of water arriving at the equator have the capability to modulate the El Nino-Southern Oscillation, while the southward transports influence the climate and biodiversity in the Tasman Sea. After 7 years of substantial in situ oceanic observational and modeling efforts, our understanding of the region has much improved. We have a refined description of the SPCZ behavior, boundary currents, pathways, and water mass transformation, including the previously undocumented Solomon Sea. The transports are large and vary substantially in a counter-intuitive way, with asymmetries and gating effects that depend on time scales.

These rates are compared to regional and global trends in ocean mass addition estimated directly using data from the Gravity Recovery and Climate Experiment (GRACE) from 2003 to 2013. Despite the two independent methods covering different time periods with differing spatial and temporal resolution, they both capture the same large-scale mass addition trend patterns including higher rates of mass addition in the North Pacific, South Atlantic, and the Indo-Atlantic sector of the Southern Ocean, and lower mass addition trends in the Indian, North Atlantic, South Pacific, and the Pacific sector of the Southern Ocean. The global mean trend of ocean mass addition is 1.5 (+ or -0.4) mm yr (super -1) for 1996-2006 from the residual method and the same for 2003-2013 from the GRACE method. Furthermore, the residual method is used to evaluate the error introduced into the mass budget if the deep steric contributions below 700, 1000, 2000, 3000, and 4000 m are neglected, revealing errors of 65%, 38%, 13%, 8%, and 4% respectively. The two methods no longer agree within error bars when only the steric contribution shallower than 1000 m is considered. Abstract Copyright (2014), American Geophysical Union. All Rights Reserved.

The mechanism that sustains the blooms is investigated with the high-resolution Ocean General Circulation Model for the Earth Simulator (OFES) products. The summer blooms in the WSEIO are separated from the coast; they occur in June, reach their maximum in August, and decay in October. With summer monsoon onset, cross-equatorial wind induces open-ocean upwelling in the WSEIO, uplifting the nutricline. The mixed layer heat budget analysis reveals that both thermal forcing and ocean processes are important for the seasonal variations of SST, especially wind-driven entrainment plays a significant role in cooling the WSEIO. These processes cause nutrient enrichment in the surface layer and trigger the phytoplankton blooms. As the summer monsoon develops, the strong wind deepens the mixed layer; the entrainment thus increases the nutrient supply and enhances the bloom. Horizontal advection associated with the Southern Gyre might also be an important process that sustains the bloom. This large clockwise gyre could advect nutrient-rich water along its route, allowing Chla to bloom in a larger area. Abstract Copyright (2014), American Geophysical Union. All Rights Reserved.

Aquarius exhibits similar biases as shown in previous comparison SSS studies, with negative biases in the tropics transitioning to positive biases in the higher latitudes when compared to WOD SSS. These biases are generally much weaker in CAP than the standard version, indicating that the biases are strongly related to the differences in algorithms used to retrieve satellite SSS. Non-Argo data utilized in the study are shown to be of great use to validate Aquarius in regions with little to no Argo coverage and helps provide SSS measurements in regions where there are known errors in Aquarius retrievals. The annual cycle of WOD and Aquarius is found to be very similar, with Aquarius being generally more coherent and robust. All three products' annual cycles compared favorably to the World Ocean Atlas 2013. The interannual changes in all three products generally corresponded well to one another and to changes in evaporation and precipitation (E-P). Overall, Aquarius compares very well with in situ sea surface salinity fields under multiple comparison examinations; however, both products have their own strengths and weaknesses and a synthesis of the two should be used to study global scale SSS variability.

Most barrier fabrics are smolder resistant when tested alone over a standard flexible polyurethane foam. However, when covered with a smolder-prone cover fabric, most barrier fabrics failed the smoldering ignition test described in the Consumer Product Safety Commission's proposed standard 16 CFR Part 1634. The results of this study suggest that the smolder-prone cover fabrics, when placed on top of a number of barrier fabrics, are capable of releasing sufficient heat to initiate the char oxidation smoldering process of some of the barrier fabrics and subsequently transmit the heat to the underlying flexible polyurethane foam. A smoldering index for barrier fabrics was derived from the measured char volume fraction of the flexible polyurethane foam by varying the barrier fabric component in the flexible polyurethane foam/barrier fabric/cover fabric mock-up systems, while holding the other two components constant. The smoldering index for self-extinguishing barrier fabrics was 0. Barrier fabrics with smoldering index of 1 or more resulted in sustained smoldering in the flexible polyurethane foam. The smoldering propensity of barrier fabrics and the amount of heat transmitted to the flexible polyurethane foam varied depending on the barrier fabric structure, fiber content, air permeability, and bulk density. Flame-retardant treatments and use of char-forming fibers showed a greater tendency for barrier fabric smolder in the presence of the smolder-prone cover fabric. Barrier fabrics with char-forming fiber blends had greater smoldering propensity as compared to barrier fabrics with low charring fiber blends. The lower the smoldering propensity of the barrier fabric, the less likely was the development of sustained smoldering in the flexible polyurethane foam.

In the second quarter of 2014, real GDP increased 4.6%. The slowdown in real GDP growth in the third quarter reflected a downturn in inventory investment and slowdowns in consumer spending, in nonresidential fixed investment, in exports, in state and local government spending, and in residential fixed investment that were partly offset by a downturn in imports and an upturn in federal government spending. Real final sales of domestic product, real GDP less inventory investment, increased 4.2% in the third quarter after increasing 3.2% in the second quarter. The GDP price index increased 1.3% in the third quarter, the same increase as in the price index for gross domestic purchases. Export prices decreased 0.7% after decreasing 0.2%, and import prices decreased 0.2% after decreasing 0.8%. Adapted from the source document.

In the early 1990s, the Bureau of Economic Analysis (BEA) began researching how R&D expenditures should be treated in the core economic accounts. BEA expanded the asset boundary to recognize business, academic, nonprofit, and government R&D expenditures as investment, not as a current expense. Treating R&D as an investment allows economists to analyze its contribution to growth and productivity using the same framework as other capital goods. This article describes the methodology underlying the measures of R&D investment and output in the national income and product accounts and the industry economic accounts.

These statistics are based on the results of the 2012 Benchmark Survey of Foreign Direct Investment in the US ('inward' direct investment). The current-dollar value added of majority-owned US affiliates, a measure of their contribution to US gross domestic product, totaled $773.8 billion in 2012. As a result, affiliates' share of US private industry value added decreased from 6.2% in 2011 to 6.1% in 2012. Meanwhile, majority-owned US affiliates employed 5.8 million workers in 2012, an increase of 1.3%, following larger increases in 2010 and 2011.

The seeps occur on steep slopes of deformed, unconsolidated hemipelagic sediments in water depths between 1952 and 2042 m. Two main areas consist of anastomosing systems of fluid flow that have incised local sediments by several tens of centimeters. No temperature anomalies were observed in the vent areas and no active flow was visually observed, suggesting that the venting may be waning. An Eh sensor deployed on a miniature autonomous plume recorder (MAPR) recorded a positive signal and the presence of live organisms indicates at least some venting is still occurring. The chemosynthetic-based ecosystem included giant mussels (Bathymodiolus sp.) with commensal polychaetes (Branchipolynoe sp.) and cocculinid epibionts, other bivalves, Siboglinida (vestimentiferan) tubeworms, other polychaetes, and shrimp, as well as associated heterotrophs, including gastropods, anemones, crabs, fish, octopods, brittle stars, and holothurians. The origin of the seeps may be related to fluid overpressure generated during the collapse of an ancestral Kick'em Jenny volcano. We suggest that deformation and burial of hemipelagic sediment at the front and base of the advancing debris avalanche led to fluid venting at the distal margin. Such deformation may be a common feature of marine avalanches in a variety of geological environments especially along continental margins, raising the possibility of creating large numbers of ephemeral seep-based ecosystems.

To address this knowledge gap, we applied a gross anatomical maturity key for Pacific cod to describe temporal and spatial patterns of reproductive status over three winter spawning seasons: 2005, 2006, and 2007. Maturity status of female Pacific cod was assessed by fishery observers during sampling of commercial catches and used to construct maps showing spawning activity in the Bering Sea and Aleutian Islands. Most spawning activity was observed on the Bering Sea shelf and Aleutian Island plateaus between 100 and 200m depth. Data for those days when a high percentage of spawning stage fish were observed were used to identify areas with concentrations of spawning fish. Spawning concentrations were identified north of Unimak Island, in the vicinity of the Pribilof Islands, at the shelf break near Zhemchug Canyon, and adjacent to islands in the central and western Aleutian Islands along the continental shelf. The spawning season was found to begin in the last days of February or early March and extend through early to mid-April. Variation in spawning time (averaging ~10 days between years) may have been associated with a change from warm (2005) to cold (2007) climate conditions during the study period. Our information on Pacific cod spawning patterns will help inform fishery management decisions, models of spawning and larval dispersal and the spatial structure of the stock.

The spatial and temporal overlap of early life stages of both species may explain their strongly correlated recruitment trends. Pelagic larvae and juveniles were collected during four research cruises in May, July and September of 2008, an exceptionally cold year, and their stomach contents were examined. Feeding success and diet composition of walleye pollock and Pacific cod were consistently different in spring, summer, and fall. Pacific cod larvae and juveniles always consumed larger and progressively fewer prey items per stomach than walleye pollock; this difference was particularly pronounced in the fall. Our data suggest that co-occurring early life stages of walleye pollock and Pacific cod were dividing prey resources rather than competing for them, at least during the exceptionally cold conditions in 2008 in the southeastern Bering Sea.

In the eastern Bering Sea, spring bloom timing has been linked to ice retreat timing and production of zooplankton and fish. A large part of the eastern Bering Sea shelf (~500km wide) is ice-covered during winter and spring. Four oceanographic moorings have been deployed along the 70-m depth contour of the eastern Bering Sea shelf with the southern location occupied annually since 1995, the two northern locations since 2004 and the remaining location since 2001. Chlorophyll a fluorescence data from the four moorings provide 37 realizations of a spring bloom and 33 realizations of a fall bloom. We found that in the eastern Bering Sea: if ice was present after mid-March, spring bloom timing was related to ice retreat timing (p<0.001, df=1, 24); if ice was absent or retreated before mid-March, a spring bloom usually occurred in May or early June (average day 148, SE=3.5, n=11). A fall bloom also commonly occurred, usually in late September (average day 274, SE=4.2, n=33), and its timing was not significantly related to the timing of storms (p=0.88, df=1, 27) or fall water column overturn (p=0.49, df=1, 27). The magnitudes of the spring and fall blooms were correlated (p=0.011, df=28). The interval between the spring and fall blooms varied between four to six months depending on year and location. We present a hypothesis to explain how the large crustacean zooplankton taxa Calanus spp. likely respond to variation in the interval between blooms (spring to fall and fall to spring).

Previous studies from the southeastern Bering Sea shelf documented substantial differences in zooplankton taxa in the Middle and Inner Shelf Domains between warm and cold years. Our investigation expands this analysis into the northern Bering Sea and the south Outer Domain, looking at zooplankton community structure during a period of climate-mediated, large-scale change. Elevated air temperatures in the early 2000s resulted in regional warming and low sea-ice extent in the southern shelf whereas the late 2000s were characterized by cold winters, extensive spring sea ice, and a well-developed pool of cold water over the entire Middle Domain. The abundance of large zooplankton taxa such as Calanus spp. (C. marshallae and C. glacialis), and Parasagitta elegans, increased from warm to cold periods, while the abundance of gelatinous zooplankton (Cnidaria) and small taxa decreased. Biomass followed the same trends as abundance, except that the biomass of small taxa in the southeastern Bering Sea remained constant due to changes in abundance of small copepod taxa (increases in Acartia spp. and Pseudocalanus spp. and decreases in Oithona spp.). Statistically significant changes in zooplankton community structure and individual species were greatest in the Middle Domain, but were evident in all shelf domains, and in both the northern and southern portions of the eastern shelf. Changes in community structure did not occur abruptly during the transition from warm to cold, but seemed to begin gradually and build as the influence of the sea ice and cold water temperatures persisted. The change occurred one year earlier in the northern than the southern Middle Shelf. These and previous observations demonstrate that lower trophic levels within the eastern Bering Sea respond to climate-mediated changes on a variety of time scales, including those shorter than the commonly accepted quasi-decadal time periods. This lack of resilience or inertia at the lowest trophic levels affects production at higher trophic levels and must be considered in management strategy evaluations of living marine resources.

Studies have examined POCs in marine mammals on a regional scale; however, limited data exists on POC concentrations relative to land use and watersheds. Objective Examine geographical variation of POC concentrations in bottlenose dolphins as it relates to land, and watershed, use. Methods POC (PCBs, DDTs, and PBDEs) concentrations were measured in blubber of bottlenose dolphins (n= 40) sampled in estuarine waters near Charleston, SC. Photo-identification sighting histories were used to assess the dolphins' use of estuarine waters in two adjacent watersheds (Cooper Subbasin and Stono Subbasin) in the study area and to determine land use (developed, forested, agriculture, and wetland) associations. Results Dolphins with greater than or equal to 75% of their sightings in the Cooper Subbasin, which is characterized by a higher degree of developed land use, exhibited higher levels of PCBs, PBDEs, and total pesticides than those with greater than or equal to 75% of their sightings in the Stono Subbasin. Observed differences were significant for capital sigma PBDEs and capital sigma DDTs/ capital sigma PCBs ratio. Significant positive correlations were observed between capital sigma PBDEs and developed land use and between capital sigma DDTs/ capital sigma PCBs and wetland land use. A significant negative correlation was observed between capital sigma DDTs/ capital sigma PCBs and developed land use. Conclusion The spatial pattern of PBDEs and the capital sigma DDTs/ capital sigma PCBs detected in dolphin blubber was shown to vary significantly with adjacent watersheds and land use associations.

Organic aerosol mass, the other major aerosol component in the Southeastern U.S., has decreased more slowly despite concurrent emission reductions in anthropogenic precursors. Summertime measurements in rural Alabama quantify the change in aerosol light extinction as a function of aerosol composition and relative humidity. Application of this relationship to composition data from 2001 to 2013 shows that a -1.1( plus or minus 0.7)% yr super(-1) decrease in extinction can be attributed to decreasing aerosol water mass caused by the change in aerosol sulfate/organic ratio. Calculated reductions in extinction agree with regional trends in ground-based and satellite-derived aerosol optical depth. The diurnally averaged summertime surface radiative effect has changed by 8.0Wm super(-2), with 19% attributed to the decrease in aerosol water.

Key aspects of climatic variability and trends in these regions are the amplification of surface warming trends with height, and the strong modulation of temperature trends by tropical sea surface temperature, largely controlled by changes in El Nino-Southern Oscillation on multiple time scales. Corollary aspects of these climate trends include the increase in a critical plant growth temperature threshold, a rise in the freezing level surface, and the possibility of enhanced subtropical drying. Anthropogenic global warming projections indicate a strong likelihood for enhancement of these observed changes.

Since then many more have followed and characterization of the genetic structure of green turtle rookeries now covers most of the global distribution of the species, benefitting conservation of this threatened species worldwide. However, important data gaps still exist across a large part of the western and central Pacific Ocean (WCPO). This large area is made up of hundreds of scattered islands and atolls of Micronesia, Melanesia, and Polynesia, most of which are remote and difficult to access. In this study, we assessed stock structure of green turtles throughout the WCPO using mitochondrial (mt) DNA from 805 turtles sampled across 25 nesting locations. We examined whether sequencing longer fragments (770 bp) of the control region increases resolution of stock structure and used genetic analysis to evaluate level of demographic connectivity among island nesting populations in the WCPO. We identified a total of 25 haplotypes characterized by polymorphism within the 770 bp sequences, including five new variants of haplotypes that were indistinguishable with shorter 384 bp reads from previous studies. Stock structure analysis indicated that rookeries separated by more than 1,000 km were significantly differentiated from each other, but neighboring rookeries within 500 km showed no genetic differentiation. Results presented in this paper establish that sequencing of longer fragments (770 bp) of the control region does in some cases increase resolution and that there are at least seven independent stocks in the region.

While general criteria have been produced, there are no guidelines or protocols that elaborate on the process from initial identification through to the protection of VMEs. Here, based upon an expert review of existing practices, a 10-step framework is proposed: (1) Comparatively assess potential VME indicator taxa and habitats in a region; (2) determine VME thresholds; (3) consider areas already known for their ecological importance; (4) compile information on the distributions of likely VME taxa and habitats, as well as related environmental data; (5) develop predictive distribution models for VME indicator taxa and habitats; (6) compile known or likely fishing impacts; (7) produce a predicted VME naturalness distribution (areas of low cumulative impacts); (8) identify areas of higher value to user groups; (9) conduct management strategy evaluations to produce trade-off scenarios; (10) review and re-iterate, until spatial management scenarios are developed that fulfil international obligations and regional conservation and management objectives. To date, regional progress has been piecemeal and incremental. The proposed 10-step framework combines these various experiences into a systematic approach.

Shipboard observations collected near Saba Bank, the U.S. and British Virgin Islands, and the Anegada Passage showed low surface salinity (35.76 plus or minus 0.05 Practical Salinity Unit (PSU)), elevated surface temperature (26.77 plus or minus 0.14 degree C), high chlorophyll-a (1.26 plus or minus 0.21 mg m-3) and high dissolved oxygen (4.90 plus or minus 0.06 mL L-1) in a 20- to 30-m thick surface layer in the riverine plume. The water was 1 degree C warmer, 1 PSU fresher, 0.3 mL L-1 higher in oxygen and 1.2 mg m-3 higher in chlorophyll-a than Atlantic Ocean waters to the north, with Caribbean surface waters showing intermediate values. Plankton net tows obtained in the upper 100 m of the water column revealed larval fish assemblages within the plume that were significantly different from those of the surrounding waters and from those encountered in the area in previous years. The plume waters contained higher concentrations of mesopelagic fish larvae from the families Myctophidae and Nomeidae, which as adults typically inhabit offshore, deep water habitats. Concentrations of larvae from inshore and reef-associated families such as Scaridae, Serranidae, Labridae and Clupeidae were lower than those found outside the plume in similar shallow areas, particularly in near-surface waters. An event like the one observed in 2009 had not been documented in at least the past 30 yr, and yet it was followed by another similarly extreme event in 2010. The ecological implications, including any long-term consequences of such recent extreme events, are important and merit further study.

Organized under the auspices of the International Surface Temperature Initiative (ISTI), an international group of scientists have spent three years collating and merging data from numerous sources to create a merged holding. This release in its recommended form consists of over 30 000 individual station records, some of which extend over the past 300 years. This article describes the sources, the chosen merge methodology, and the resulting databank characteristics. Several variants of the databank have also been released that reflect the structural uncertainty in merging datasets. Variants differ in, for example, the order in which sources are considered and the degree of congruence required in station geolocation for consideration as a merged or unique record. Also described is a version control protocol that will be applied in the event of updates. Future updates are envisaged with the addition of new data sources, and with changes in processing, where public feedback is always welcomed. Major updates, when necessary, will always be accompanied by a new journal paper. This databank release forms the foundation for the construction of new global land surface air temperature analyses by the global research community and their assessment by the ISTI's benchmarking and assessment working group.

The Aichi Biodiversity Targets were designed to promote and implement the Convention on Biological Diversity (CBD) by providing a framework for action to save biodiversity and enhance its benefits for people. Specifically, Target 11 aims to protect 10% of all seas by 2020. The percentage of the world's oceans that are protected has increased steadily in recent years, mainly due to very large marine protected areas (MPAs). 2. The issue of making major gains in achieving protection targets through 'going big' has brought added scrutiny to the subject of MPAs. There is economy in scale, but several people have called into question whether going large will protect representative habitat and result in true protection, or whether it is merely a politically expedient way for some nations to attain targets by creating paper parks, while avoiding tough conservation decisions. 3. The recent creation of large MPAs has greatly enhanced the chance of achieving global protection targets. Large areas typically contain several ecosystems and habitats that interact ecologically, and allow for more holistic conservation. The interactions between ecosystems in large MPAs occur without many of the problems associated with networks of smaller MPAs, where the connectivity between sites is often affected by human activities. 4. The disadvantages of large MPAs include difficulties of surveillance, enforcement and monitoring of vast offshore areas, as well as high total costs. While the cost per unit area may be lower for large MPAs, conducting surveillance and monitoring in such vast areas requires much more expensive technologies. 5. Large MPAs complement and add to existing management and conservation measures. Decision makers should consider designating them as one of a suite of possible protection measures. Besides greatly enhancing the chance of reaching agreed biodiversity targets, large MPAs improve the quality of conservation. Copyright copyright 2014 John Wiley & Sons, Ltd.

However, the temperature-dependent vital rates and settlement dynamics for this species have not been described in detail. We reared northern rock sole larvae in the laboratory to measure growth, condition, development and settlement parameters across four temperatures (2, 4, 7 and 10 degree C). Both length and mass-measured growth rates increased with temperature and were best described by non-linear regression. Residuals of the length-mass relationships were positively related to temperature, indicating larval condition also increased with temperature. Larval development and settlement were largely size dependent, resulting in reduced larval stage duration and earlier settlement at higher temperatures owing to more rapid growth at elevated temperatures. However, larvae at colder temperatures were less developed at a given size, but more likely to settle at smaller sizes than larvae reared in warmer conditions. These temperature-response parameters can be used to refine current and future transport models for northern rock sole larvae under changing environmental conditions in the North Pacific.

Large-eddy simulations are analyzed to study the effects of ice habit and number concentration on the bulk ice and liquid masses, dynamics, and lifetime of Arctic mixed-phase boundary layer clouds. The microphysical and dynamical evolution simulated using the adaptive habit scheme is compared with that assuming spherical particles with a density of bulk ice or a reduced density and with mass-dimensional parameterizations. It is found that the adaptive habit method returns an increased (decreased) ice (liquid) mass as compared to spheres and provides a more accurate simulation as compared to dendrite mass-size relations. Using the adaptive habit method, simulations are then completed to understand the microphysical and dynamical interactions within a single-layer mixed-phase stratocumulus cloud observed during flight 31 of the Indirect and Semi-Direct Aerosol Campaign. With cloud-top longwave radiative cooling as a function of liquid mass acting as the primary dynamic driver of turbulent eddies within these clouds, the consumption of liquid at the expense of ice growth and subsequent sedimentation holds a strong control on the cloud lifetime. Ice concentrations greater than or equal to 4 L super(-1) collapse the liquid layer without any external maintaining sources. Layer maintenance is possible at 4 L super(-1) when a constant cloud-top cooling rate or the water mass lost due to sedimentation is supplied. Larger concentrations require a more substantial source of latent or sensible heat for mixed-phase persistence.

After exposure of nano-TiO sub(2) to varying concentrations of Suwannee River fulvic acid (SRFA) and Bacillus subtilis exudate in high and low ionic strength (IS) solutions at pH 3 to pH 7.5, aggregation behaviors were evaluated via dynamic light scattering (DLS) measurements and sedimentation studies. Although pH, IS, and NOM concentration exerted strong controls on nano-TiO sub(2) aggregation behaviors, suspensions exposed to either SRFA or bacterial exudate at normalized dissolved organic carbon (DOC) concentrations exhibited remarkably similar behaviors. In high IS systems, nano-TiO sub(2) exposed to either SRFA or bacterial exudate sedimented rapidly, except in the presence of high NOM concentrations at pH 6 and 7.5. Low IS treatments exhibited a larger range of effects. In fact, relative to NOM-free controls, nano-TiO sub(2) aggregates in SRFA and bacterial exudate exposures sedimented up to 14 times faster at pH 3 and up to 13 times slower at pH 7.5. Adsorption of organic molecules onto nano-TiO sub(2) can enhance aggregation via colloidal bridging and/or charge neutralization, or with more complete surface coverage, can diminish aggregation via electrostatic repulsion and/or steric hindrance. Collectively, these data suggest that solution pH, IS, and NOM concentration, and to a lesser extent NOM origin, can control the fate and mobility of nano-TiO sub(2) in geologic systems.

This study develops a multiregional computable general equilibrium (MRCGE) model of three US economic regions: Alaska (AK), the West Coast (WC), and the rest of the US (RUS). The model is applied to issues affecting Alaskan fisheries, and is used to calculate the multiregional economic effects, including spread effects, of changes in: (i) the volume of fish caught off AK; (ii) the demand for Alaskan seafood by both the US and the rest of the world; and (iii) currency exchange rates.

The validity of non-English cognitive interviews is of concern among researchers because the cognitive interviewing technique was developed based on the communicative norms of Western cultures where directness and openness in expressing one's opinion is encouraged. However, different communicative norms are present in Asian languages and cultures. To date, little research has been conducted on this topic. Using qualitative and quantitative analysis, we compared survey question problems identified through the cognitive interviews conducted in English and in Korean and found that Korean cognitive interviewing was indeed effective for detecting problematic survey questions.

Despite its widespread use in high content analysis and other imaging applications, few published methods exist for evaluating and benchmarking the analytical performance of a microscope. Easy-to-use benchmarking methods would facilitate the use of fluorescence imaging as a quantitative analytical tool in research applications, and would aid the determination of instrumental method validation for commercial product development applications. We describe and evaluate an automated method to characterize a fluorescence imaging system's performance by benchmarking the detection threshold, saturation, and linear dynamic range to a reference material. The benchmarking procedure is demonstrated using two different materials as the reference material, uranyl-ion-doped glass and Schott 475 GG filter glass. Both are suitable candidate reference materials that are homogeneously fluorescent and highly photostable, and the Schott 475 GG filter glass is currently commercially available. In addition to benchmarking the analytical performance, we also demonstrate that the reference materials provide for accurate day to day intensity calibration. Published 2014 Wiley Periodicals Inc.

Here a novel method for in situ visualization of AgNP release from silver-impregnated wound dressings is introduced. By combining an environmental scanning electron microscope, a gaseous analytical detector and a peltier cooling stage, this technique provides near-instantaneous nanoscale characterization of interactions between individual water droplets and AgNPs. We show that dressings with different silver application methods have very distinct AgNP release dynamics. Specifically, water condensation on dressings with AgNP deposited directly on the fiber surface resulted in substantial and rapid AgNP release. By comparison, AgNP release from wound dressing with nanoparticles grown, not deposited, from the fiber surface was either much slower or negligible. Our methodology complements standard bulk techniques for studying of silver release from fabrics by providing dynamic nanoscale information about mechanisms governing AgNP release from individual fibers. Thus coupling these nano and macro-scale methods can provide insight into how the wound dressing fabrication could be engineered to optimize AgNP release for different applications.

Using ocean and atmosphere reanalysis products, it is shown here that the strength of the SAA from February to May impacts the timing of the cold tongue onset and the intensity of its development in the eastern equatorial Atlantic via anomalous tropical wind power. This modulation in the timing and amplitude of seasonal cold tongue development manifests itself via SST anomalies peaking between June and August. The timing and impact of this connection is not completely symmetric for warm and cold events. For cold events, an anomalously strong SAA in February and March leads to positive wind power anomalies from February to June resulting in an early cold tongue onset and subsequent cold SST anomalies in June and July. For warm events, the anomalously weak SAA persists until May, generating negative wind power anomalies that lead to a late cold tongue onset as well as a suppression of the cold tongue development and associated warm SST anomalies. Mechanisms by which SAA-induced wind power variations south of the equator influence eastern equatorial Atlantic SST are discussed, including ocean adjustment via Rossby and Kelvin wave propagation, meridional advection, and local intraseasonal wind variations.

The present climate simulation shows a fairly realistic global TC frequency, seasonal cycle, and geographical distribution. The model has some notable biases in regional TC activity, including simulating too few TCs in the North Atlantic. The regional biases in TC activity are associated with simulation biases in the large-scale environment such as sea surface temperature, vertical wind shear, and vertical velocity. Despite these biases, the model simulates the large-scale variations of TC activity induced by El Nino-Southern Oscillation fairly realistically. The response of TC activity in the model to global warming is investigated by comparing the present climate with a CO sub(2) doubling experiment. Globally, TC frequency decreases (-19%) while the intensity increases (+2.7%) in response to CO sub(2) doubling, consistent with previous studies. The average TC lifetime decreases by -4.6%, while the TC size and rainfall increase by about 3% and 12%, respectively. These changes are generally reproduced across the different basins in terms of the sign of the change, although the percent changes vary from basin to basin and within individual basins. For the Atlantic basin, although there is an overall reduction in frequency from CO sub(2) doubling, the warmed climate exhibits increased interannual hurricane frequency variability so that the simulated Atlantic TC activity is enhanced more during unusually warm years in the CO sub(2)-warmed climate relative to that in unusually warm years in the control climate.

AN - 1618828156; 25078538 AB - Toxic cyanobacteria blooms are a growing concern for public health and safety, due in part to the production of the hepatotoxin microcystin by certain species, including Microcystis aeruginosa. Management strategies for controlling cyanobacteria blooms include algaecide treatments, often with copper sulfate, and more recently oxidizers such as sodium percarbonate that produce hydrogen peroxide. This study assessed the effects of two copper-containing algaecides and one sodium percarbonate-containing algaecide on mitigating cell numbers and toxin content of cultured M. aeruginosa and summer (July) bloom samples of Anabaenopsis sp. in a brackish stormwater detention pond. Monitoring of the bloom revealed that Anabaenopsis sp. was associated with elevated levels of orthophosphate compared to nitrogen (dissolved inorganic nitrogen to phosphorus ratios were 0.19-1.80), and the bloom decline (September-October) was likely due to lower autumn water temperatures combined with potential grazing by the dinoflagellate Protoperidinium quinquecorne. Laboratory-based algaecide experiments included three dose levels, and cyanobacteria cell numbers and microcystin concentrations (particulate and dissolved) were evaluated over 7 d. Following exposure, copper-containing treatments generally had lower cell numbers than either sodium percarbonate-containing or control (no algaecide) treatments. Addition of algaecides did not reduce overall microcystin levels, and a release of toxin from the particulate to dissolved phase was observed in most treatments. These findings indicate that algaecide applications may visibly control cyanobacteria bloom densities, but not necessarily toxin concentrations, and have implications for public health and safety.

The effect of this spill on growth was examined for brown shrimp Farfantepenaeus aztecus and white shrimp Litopenaeus setiferus held for 7 days in field mesocosms in Barataria Bay during May and August 2011, respectively. The experiments each had 10 treatment combinations, five apparent oil levels, each one with and without added food. Mesocosms were placed in northern Barataria Bay along shorelines that varied in oiling (designated as heavy, moderate, light, very light, or none based on NOAA surveys), and shrimp in half the mesocosms received additional food. Polycyclic aromatic hydrocarbon (PAH) concentrations determined from sediment cores collected at each mesocosm were significantly higher at heavy and moderate than very light shorelines and also higher at moderate than light and none shorelines. Brown shrimp grew more slowly at heavy than very light or none shorelines, and a statistically significant negative relationship was detected between brown shrimp growth rates and sediment PAH concentrations. In August, PAH sediment concentrations had decreased significantly from the values measured in May, no significant difference in white shrimp growth rates was detected among oiling levels, and no relationship was detected between white shrimp growth and sediment PAH concentrations. Both brown shrimp and white shrimp grew more rapidly in mesocosms where food was added. Our study shows that exposure to nonlethal concentrations of petroleum hydrocarbons can reduce growth rates of juvenile penaeid shrimps.

It is a major cause of seafood-associated gastroenteritis and is generally associated with consumption of raw or undercooked seafood, especially oysters. This study presents a snapshot of total V. parahaemolyticus densities in surface waters and shellstock American oysters (Crassostrea virginica) from open and closed shellfish harvesting areas, as well as "more rural areas" on two different US coasts, the Atlantic and the Gulf. Sampling was conducted from 2001 to 2003 at five sites near Charleston/Georgetown, SC and at four locations in the Gulfport/Pascagoula, MS area. V. parahaemolyticus numbers were determined by a direct plating method using an alkaline-phosphatase-labeled DNA probe targeting the species-specific thermolabile hemolysin gene (tlh) that was used for identification of bacterial isolates. The greatest difference between the two coasts was salinity; mean salinity in SC surface waters was 32.9 ppt, whereas the mean salinity in MS waters was 19.2 ppt, indicating more freshwater input into MS shellfish harvesting areas during the study period. The mean V. parahaemolyticus numbers in oysters were almost identical between the two states (567.4 vs. 560.1 CFU/g). Bacterial numbers in the majority of surface water samples from both states were at or below the limit of detection (LOD=<10 CFU/mL). The bacterial concentrations determined during this study predict a low public health risk from consumption of oysters in shellfish growing areas on either the Gulf or the Atlantic US coast.

Part II: Baroclinic basic vortex AN - 1566828942; 20719932 AB - The effect of baroclinicity on vortex axisymmetrization is examined within a two-layer dynamical model. Three basic state vortices are constructed with varying degrees of baroclinicity: (i) barotropic, (ii) weak baroclinic, and (iii) strong baroclinic. The linear and nonlinear evolution of wavenumber-2 baroclinic disturbances are examined in each of the three basic state vortices. The results show that the radial propagating speed of the vortex Rossby wave at the lower level is larger with the stronger baroclinicity, resulting in a faster linear axisymmetrization process in the stronger baroclinic vortex. It is found that the nonlinear axisymmetrization process takes the longest time in the strongest baroclinic vortex among the three different basic vortices due to the weaker kinetic energy transfer from asymmetric to symmetric circulations at the lower level. A major finding in this study is that the same initial asymmetric perturbation can have different effects on symmetric vortices depending on the initial vortex baroclinicity. In numerical weather prediction models, this implies that there exists a sensitivity of the subsequent structural and intensity change solely due to the specification of the initial vertical shear of the tropical cyclone vortex.

Part I: Barotropic basic vortex AN - 1566828802; 20719931 AB - The barotropic and baroclinic disturbances axisymmetrized by the barotropic basic vortex are examined in an idealized modeling framework consisting of two layers. Using a Wentzel-Kramers-Brillouin approach, the radial propagation of a baroclinic disturbance is shown to be slower than a barotropic disturbance, resulting in a slower linear axisymmetrization for baroclinic disturbances. The slower-propagating baroclinic waves also cause more baroclinic asymmetric kinetic energy to be transferred directly to the barotropic symmetric vortex than from barotropic disturbances, resulting in a faster axisymmetrization process in the nonlinear baroclinic wave case than in the nonlinear barotropic wave case.

AN - 1619315194; 25354711 AB - High-quality frequency references are the cornerstones in position, navigation and timing applications of both scientific and commercial domains. Optomechanical oscillators, with direct coupling to continuous-wave light and non-material-limited f × Q product, are long regarded as a potential platform for frequency reference in radio-frequency-photonic architectures. However, one major challenge is the compatibility with standard CMOS fabrication processes while maintaining optomechanical high quality performance. Here we demonstrate the monolithic integration of photonic crystal optomechanical oscillators and on-chip high speed Ge detectors based on the silicon CMOS platform. With the generation of both high harmonics (up to 59 th order) and subharmonics (down to 1/4), our chipset provides multiple frequency tones for applications in both frequency multipliers and dividers. The phase noise is measured down to -125 dBc/Hz at 10 kHz offset at ~400 μW dropped-in powers, one of the lowest noise optomechanical oscillators to date and in room-temperature and atmospheric non-vacuum operating conditions. These characteristics enable optomechanical oscillators as a frequency reference platform for radio-frequency-photonic information processing.

However, it is still unknown how far atmospheric emissions from these activities have been transported. Since the timing of metallurgical activities is currently estimated from scarce archaeological discoveries, the availability of reliable and continuous records to refine the timing of past metal deposition in South America is essential, as it provides an alternative to discontinuous archives, as well as evidence for global trace metal transport. We show in a peat record from Tierra del Fuego that anthropogenic metals likely have been emitted into the atmosphere and transported from NSA to southern South America (SSA) over the last 4200 yrs. These findings are supported by modern time back-trajectories from NSA to SSA. We further show that apparent anthropogenic Cu and Sb emissions predate any archaeological evidence for metallurgical activities. Lead and Sn were also emitted into the atmosphere as by-products of Inca and Spanish metallurgy, whereas local coal-gold rushes and the industrial revolution contributed to local contamination. We suggest that the onset of pre-Hispanic metallurgical activities is earlier than previously reported from archaeological records and that atmospheric emissions of metals were transported from NSA to SSA.

A few studies have shown the benefits of assimilating satellite soil moisture data in land surface models (LSMs), which are the components of most NWP models. In this study, synthetic experiments are conducted to determine how soil moisture data quality control may impact the benefit of their assimilation into LSMs. It is found that using green vegetation fraction to quality control the SMOPS soil moisture product may significantly increase the benefit of assimilating it into Noah LSM in terms of increasing the agreement of Noah LSM surface and root zone soil moisture simulations with the corresponding in situ measurements. The quality control procedures and parameters are suggested for the assimilation of SMOPS data into NWS NWP models. Abstract Copyright (2014), American Geophysical Union. All Rights Reserved.

AN - 1694700832; 16303 AB - PURPOSE: Harvest specifications and management measures for the 2015-2016 biennial period are based on the best available scientific information. Every 2 years harvest specifications, including the overfishing limits (OFLs), acceptable biological catches (ABCs), and annual catch limits (ACLs) are considered for each management unit consistent with the policies and procedures established in the Groundfish FMP and in compliance with other applicable law. For overfished species, the ACLs are based on the rebuilding plans intended to rebuild the stock in as short a time as possible taking into account the status and biology, the needs of fishing communities, and the interaction of the overfished stock with the marine ecosystem. Accountability measures are proposed to prevent catch from exceeding the annual limits set for management units. The accountability measures include ACL reductions (set asides), allocations, and adjustments to management measures. The restructuring of stock complexes for Minor Slope Rockfish and Other Fish stock complexes are considered for consistency with National Standard 1 Guidelines at 50 CFR 6060.310(d)(8). Most groundfish species managed within stock complexes are data-poor stocks without full stock assessments. The proposed action considers the impacts of management actions on individual stocks within the complexes given the differences in vulnerability, life history, and distribution. The proposed action considers designating ecosystem component species (EC species), which are non-targeted groundfish stocks that are not subject to overfishing and have not been determined to be overfished, or approaching the overfished threshold; and that are not generally retained for sale or personal use. EC species are monitored, but ACLs are not set for them. For conservation purposes, the proposed action considers designating several species not managed under any FMP as EC species under the Groundfish FMP as these are species caught during fishing activity managed under the Groundfish FMP. Amendment 24 to the Groundfish FMP proposes to establish procedures for deriving harvest specifications in the absence of Council action and defining the scope of management actions that may occur along with the harvest specifications. Harvest specification values based on default harvest control rules would be defined for stocks and stock complexes but would not change the Councils ability to use discretion to modify the harvest control rule in future biennial cycles. The proposed action is intended to reducing the number of decision points needed during Council deliberations on the biennial harvest specifications and management measures.

AN - 1614700164; 25162377 AB - Titanium dioxide nanoparticles (TiO2 NPs) are found in numerous commercial and personal care products. Thus, it is necessary to understand and characterize their potential environmental health and safety risks. It is well-known that photoactivated TiO2 NPs in aerated aqueous solutions can generate highly reactive hydroxyl radicals ((•)OH), which can damage DNA. Surprisingly, recent in vitro studies utilizing the comet assay have shown that nonphotoactivated TiO2 NPs kept in the dark can also induce DNA damage. In this work, we utilize stable isotope-dilution gas chromatography/tandem mass spectrometry to quantitatively characterize the levels and types of oxidatively generated base lesions in genomic DNA exposed to NIST Standard Reference Material TiO2 NPs (Degussa P25) under precisely controlled illumination conditions. We show that DNA samples incubated in the dark for 24 h with TiO2 NPs (0.5-50 μg/mL) do not lead to the formation of base lesions. However, when the same DNA is exposed to either visible light from 400 to 800 nm (energy dose of ∼14.5 kJ/m(2)) for 24 h or UVA light at 370 nm for 30 min (energy dose of ∼10 kJ/m(2)), there is a significant formation of lesions at the 50 μg/mL dose for the visible light exposure and a significant formation of lesions at the 5 and 50 μg/mL doses for the UVA light exposure. These findings suggest that commercial P25 TiO2 NPs do not have an inherent capacity to oxidatively damage DNA bases in the absence of sufficient photoactivation; however, TiO2 NPs exposed to electromagnetic radiation within the visible portion of the light spectrum can induce the formation of DNA lesions. On the basis of these findings, comet assay processing of cells exposed to TiO2 should be performed in the dark to minimize potential artifacts from laboratory light.

Computed tomography and magnetic resonance imaging revealed gas bubble accumulation in the vasculature, organ parenchyma, mandibular fat pads, and subdermal sheath as well as a gas-filled cavity within the liver, mild caudal abdominal effusion, and fluid in the uterus. Gross examination confirmed these findings and also identified mild ulcerations on the palate, ventral skin, and flukes, uterine necrosis, and multifocal parenchymal cavitations in the brain. Histological review demonstrated necrosis and round clear spaces interpreted as gas bubbles with associated bacterial rods within the brain, liver, spleen, and lymph nodes. Anaerobic cultures of the lung, spleen, liver, bone marrow, and abdominal fluid yielded Clostridium perfringens, which was further identified as type A via a multiplex PCR assay. The gas composition of sampled bubbles was typical of putrefaction gases, which is consistent with the by-products of C. perfringens, a gas-producing bacterium. Gas bubble formation in marine mammals due to barotrauma, and peri- or postmortem off-gassing of supersaturated tissues and blood has been previously described. This case study concluded that a systemic infection of C. perfringens likely resulted in production of gas and toxins, causing tissue necrosis.

AN - 1694475002; 16287 AB - PURPOSE: There are several needs and purposes for developing Omnibus Essential Fish Habitat (EFH) Amendment 2. Purposes include designating EFH (A) and minimizing adverse fishery effects on EFH (B). These actions are needed to meet requirements of the Magnuson Stevens Fishery Conservation and Management Act. Specific recommendations for EFH designation and adverse effects minimization are provided in the EFH regulatory guidelines, published in their final form in January 2002. The guidelines specify that to meet Purpose A, the Councils should designate EFH for all managed species of finfish and shellfish, by life history stage, using both text descriptions and maps delimiting potential EFH areas. Although some designations, specifically skates, wolffish, and red crab, are more recent, many of the New England designations were developed for the 1998 Omnibus EFH Amendment and the new designations proposed in this action include additional years of distribution data as well as information about depth and temperature preferences. EFH designations help the Council identify habitats where adverse impacts should be minimized (Purpose B). Prior efforts to minimize the adverse effects of Council-managed fisheries on EFH have been largely developed and implemented plan by plan, although fishery effects on EFH are cumulative across FMPs because fish and fishery distributions are overlapping across species and plans. This action is needed to reevaluate and integrate habitat management measures across the fisheries managed by the Council, and to update these measures given new scientific information about habitat distributions and fishing impacts. EFH designations also inform fisheries management decision making, helping the Council and its stakeholders to understand species distributions and habitat requirements. Finally, EFH designations facilitate outside consultations between NMFS and other ocean users regarding non-fishing projects that may impact fish habitats. Habitat consultations help minimize impacts on EFH, particularly impacts of non-fishery activities. Purpose C of the amendment is to identify other actions to encourage conservation and enhancement of such habitat. One set of alternatives related to this purpose is to designate Habitat Areas of Particular Concern. An Habitat Area of Particular Concern is a subset of EFH that represents particularly unique, ecologically important, and/or vulnerable habitat types. This action is needed to highlight these special areas, as Habitat Areas of Particular Concern help inform and receive elevated consideration for both fishery management and EFH consultations. Another set of alternatives that relates to Purpose C is the designation of Dedicated Habitat Research Areas, which will help the Council to better understand how habitat management measures influence stock productivity, to allow for the design of more effective conservation measures in future actions. Another purpose of this amendment is to review and consider revising the rolling closures and year round groundfish closed areas. This is needed to ensure that spatial management measures are contributing to the realization of optimum yield in the groundfish fishery. Spatial overlaps between habitat and groundfish management areas make the EFH amendment an appropriate action to meet this need. Specifically, the Council was concerned that the continued existence of the year-round groundfish closures could potentially undermine the practicality of new EFH management areas. In addition, changes to spatial management measure may be appropriate given substantial shifts in groundfish management strategy since the implementation of Amendment 16 to the Northeast Multispecies Fishery Management Plan, which implemented Annual Catch Limits in the fishery and significantly expanded the sector program. There are two elements to this overall purpose. The first groundfish-specific purpose of this amendment is to increase protection for juvenile groundfish and their habitats (Purpose D). Success at younger ages can have positive productivity benefits for managed resources, and therefore action is needed to protect the habitats important for juvenile groundfish, particularly for commercially valuable species. Scientific data indicate that the current year-round habitat management areas do not optimally encompass concentrations of juvenile groundfish. A second groundfish-specific purpose of this amendment is to identify seasonal closed areas in the NE Multispecies FMP that would reduce impacts on spawning groundfish and on the spawning activity of key groundfish species, since the protection of spawning fish is needed to sustainably manage stocks (Purpose E). Therefore additional alternatives were needed to meet this need.

We combined new radar altimeter measurements from satellites CryoSat-2 and Jason-1 with existing data to construct a global marine gravity model that is two times more accurate than previous models. We found an extinct spreading ridge in the Gulf of Mexico, a major propagating rift in the South Atlantic Ocean, abyssal hill fabric on slow-spreading ridges, and thousands of previously uncharted seamounts. These discoveries allow us to understand regional tectonic processes and highlight the importance of satellite-derived gravity models as one of the primary tools for the investigation of remote ocean basins.

We investigated whether stormwater control measures (SCMs), a form of green infrastructure, integrated into restored and degraded urban stream networks can influence watershed nitrogen loads. We hypothesized that hydrologically connected floodplains and SCMs are "hot spots" for nitrogen removal through denitrification because they have ample organic carbon, low dissolved oxygen levels, and extended hydrologic residence times. We tested this hypothesis by comparing nitrogen retention metrics in two urban stream networks (one restored and one urban degraded) that each contain SCMs, and a forested reference watershed at the Baltimore Long-Term Ecological Research site. We used an urban watershed continuum approach which included sampling over both space and time with a combination of: (1) longitudinal reach-scale mass balances of nitrogen and carbon conducted over 2 years during baseflow and storms (n = 24 sampling dates 15 stream reaches = 360) and (2) super(15)N push-pull tracer experiments to measure in situ denitrification in SCMs and floodplain features (n = 72). The SCMs consisted of inline wetlands installed below a storm drain outfall at one urban site (restored Spring Branch) and a wetland/wet pond configured in an oxbow design to receive water during high flow events at another highly urbanized site (Gwynns Run). The SCMs significantly decreased total dissolved nitrogen (TDN) concentrations at both sites and significantly increased dissolved organic carbon concentrations at one site. At Spring Branch, TDN retention estimated by mass balance (g/day) was ~150 times higher within the stream network than the SCMs. There were no significant differences between mean in situ denitrification rates between SCMs and hydrologically connected floodplains. Longitudinal N budgets along the stream network showed that hydrologically connected floodplains were important sites for watershed nitrogen retention due to groundwater-surface water interactions. Overall, our results indicate that hydrologic variability can influence nitrogen source/sink dynamics along engineered stream networks. Our analysis also suggests that some major predictors for watershed N retention were: (1) streamwater and groundwater flux through stream restoration or stormwater management controls, (2) hydrologic residence times, and (3) surface area of hydrologically connected features.

Boninite lava and pyroclasts were observed erupting from its summit in 2009, and hydroacoustic data from a succession of hydrophones moored nearby show near-continuous eruptive activity from January 2009 to early 2011. Successive differencing of seven multibeam bathymetric surveys of the volcano made in the 1996-2012 period reveals a pattern of extended constructional volcanism on the summit and northwest flank punctuated by eruptions along the volcano's WSW rift zone (WSWRZ). Away from the summit, the volumetrically largest eruption during the observational period occurred between May 2010 and November 2011 at approximately 2920 m depth near the base of the WSWRZ. The (nearly) equally long ENE rift zone did not experience any volcanic activity during the 1996-2012 period. The cessation of summit volcanism recorded on the moored hydrophone was accompanied or followed by the formation of a small summit crater and a landslide on the eastern flank. Water column sensors, analysis of gas samples in the overlying hydrothermal plume and dives with a remotely operated vehicle in September 2012 confirmed that the summit eruption had ceased. Based on the historical eruption rates calculated using the bathymetric differencing technique, the volcano could be as young as several thousand years.

While calibration is initially performed at observation locations only, geostatistical methods are used to provide predictive distributions on the entire grid. The incorporation of land-use information in this interpolation scheme further improves predictive performance, even though a simpler statistical model than in the original approach is used. The assessment of predictive performance and calibration is carried out with dynamical forecasts of 2 m temperatures by the COSMO-DE-EPS, an application of the COSMO (Consortium for Small-scale Modeling) model system which covers Germany and neighbouring countries.

Simulations of these effects were carried out using the Coupled Hydrosphere-Atmosphere Research Model (CHARM), driven by output from the Canadian General Circulation Model version 3 (CRCM3) for past and future time periods. This results in increased downward longwave radiation and near-surface air temperature. The air temperature increases during summer have strong spatial minima directly over the lakes that are limited to the lowest model layer and seem to be associated with frequent fog depicted by CHARM. Precipitation is also generally increased, with the most spatially coherent, and among the strongest, increases occurring in the near-shore lake effect zones during winter. Evapotranspiration is generally increased, although only weakly over land, but very strongly over the lakes during winter. Water temperatures are increased and the summer stratification pattern (warmer water overlying colder) is established earlier in the year. Ice cover is diminished and limited to shallow parts of the lakes. Several bugs and shortcomings in CHARM are identified for correction in future development and use.

Meteotsunami forecasting shares many similarities with traditional tsunami forecasting, though the characterization and integration of the source with numerical forecast models is much different. Given meteotsunami source characterization through atmospheric observations and models, it is conceivable that meteotsunami alerts could be issued and their impact forecasted using existing tsunami forecast models with high-resolution coastal definition. To test this, the 2008 Boothbay, Maine, meteotsunami is simulated using an atmospheric source consisting of a moving pressure disturbance coupled with a tsunami forecast model. Sensitivities of the modeled impact to the source characteristics, such as speed, wavelength, and direction, are also tested. Results show that the observed impact can be re-created through numerical modeling when the pressure disturbance period is roughly matched with the harbor resonance and observed meteotsunami period.

Johan Hjort's critical period hypothesis, and its decedents, remain a dominant theme and focuses on year-class success as mediated by prey availability and feeding. Bottom-up forcing, a related hypothesis, focuses on the sequential transfer of energy through the pelagic foodweb from primary productivity to fishery productivity. Another approach assumes that trophic interactions of adults determine abundance. Fisheries assessment and management, however, is based on the hypothesis that fishery abundance is determined by time-varying fishing and year-class success related to spawning-stock biomass. These approaches, their basic hypotheses, and underlying processes and mechanisms suggest very different dynamics for fishery populations. Other hypotheses challenge these traditional views: predation of early life stages, parental condition, shifting migration pathways, and physiological limits. Support for these other hypotheses is reviewed and the research needs are described to apply these hypotheses to fisheries assessment and management. Some of these hypotheses were identified by Hjort (e.g. parental condition hypothesis) and others are relative new (e.g. early life stage predation hypothesis). Moving into the future, we should focus on Hjort's approach: multi-hypothesis, integrative, and interdisciplinary. A range of hypotheses should be pursued with an emphasis on comparing and linking multiple hypotheses. The results then must be incorporated into fishery assessments and management decisions to support the long-term sustainability of exploited species and the conservation of threatened and endangered species.

We derive a simplified risk analysis for aggregate fish communities as a preliminary tool to identify priorities for further detailed assessment. Because some of the largest observed rates of sea surface temperature increase are on the northeast US continental shelf, we focused on climate change-driven risks to marine communities in this region. We evaluated climate vulnerability for six communities across two ecosystems: both commercial and non-commercial demersal fish, pelagic fish, and benthic invertebrates in the Gulf of Maine (GOM) and Mid-Atlantic bight (MAB). We first evaluated the probability that anticipated climate changes (e.g. warming water, decreased salinity, increased acidity, altered boundary currents) would occur in these regions, and rated the potential severity of change over the next 10 years. Then, we evaluated the sensitivity of each biological community in each region using 12 attributes (e.g. habitat and prey specificity, temperature and acidity sensitivity, larval dispersal, adult mobility, population productivity, etc.). Exposure to the key climate risks was related to community sensitivity in each region for an overall assessment of climate vulnerability. Climate risks from increased surface water temperature, sea level rise, and earlier spring were rated moderate to high in both regions, with additional moderate to high risks in the GOM from increased bottom temperature, stratification, and river inputs. Benthic invertebrates were rated most sensitive, with demersals intermediate and pelagics lowest. Two MAB communities were rated more sensitive than corresponding GOM communities, but greater short-term climate risks in the GOM indicated increased exposure for GOM communities. Overall, this simple analysis may help prioritize short-term regional climate risk management action, thus addressing key conditions related to fishery fluctuations beyond fishing itself.

In the first quarter, real GDP decreased 2.1%. The third estimate of real GDP growth was revised up 0.4 percentage point from the second estimate. Increases in nonresidential fixed investment and in exports were larger than previously estimated. Real GDP growth turned up in the second quarter. The upturn primarily reflected upturns in exports and in inventory investment, pickups in nonresidential fixed investment and in consumer spending, and upturns in state and local government spending and in residential fixed investment that were partly offset by a pickup in imports. Consumer spending for services was revised up slightly. An upward revision to spending for health care services was mostly offset by downward revisions to spending for 'other' services (primarily communication services) and to spending for recreation services.

GDP by metropolitan area -- the metropolitan area counterpart to GDP in the national income and product accounts -- is the most comprehensive measure of overall economic activity in a metropolitan area. In September, BEA released advance current-dollar and chained-dollar (real) statistics on GDP by metropolitan area for 2013. Metropolitan areas produced 90.3% of the nation's GDP in 2013. Collectively, GDP of the five largest metropolitan areas accounted for 23.2% of national GDP in 2013. Metropolitan areas produced 90.3% of the nation's GDP in 2013. Adapted from the source document.

The negative net international investment position represents a US net liability to the rest of the world. At the end of the first quarter of 2014, the net position was -$5,511.7 billion (revised). US assets were $24,933.3 billion at the end of the second quarter, compared with $24,020.1 billion at the end of the first quarter. The $913.2 billion increase reflected an $882.2 billion increase in the value of assets excluding financial derivatives and a $31.1 billion increase in the value of financial derivatives. US assets at the end of the first quarter were revised to $24,020.1 billion from $23,601.5 billion, and US liabilities were revised to $29,531.7 billion from $29,140.8 billion.

These statistics reflect the annual revision of the national income and product accounts, released on Jul 31, 2014, and new benchmark estimates of private fixed investment by industry and by legal form of organization. BEA undertakes benchmark revisions of the fixed assets accounts (FAA) roughly every 5 years to improve the accuracy and relevance of its estimates by incorporating the most complete and reliable source data available and by improving and updating the definitions and classifications of the FAA components. Revised estimates of FAA private fixed investment by industry and by legal form of organization reflect benchmarked levels of investment for 2007. For benchmark years in which the economic census occurs (such as 2002 and 2007), additional data on private fixed investment by industry and by legal form for specific asset types are available.

The Bureau of Economic Analysis has published annual regional gross domestic product (GDP) statistics since 1985, and these statistics have become an important measure of state economies. However, there are also some shortcomings. Annual GDP by state statistics are not available until at least 6 months after the end of a calendar year and are of limited use in analyzing economic performance from quarter to quarter. US real GDP by state increased 2.8% in the fourth quarter of 2013 after rising 4.2% in the third quarter, 2.5% in the second quarter, and 1.1% in the first quarter. In the fourth quarter of 2013, real GDP increased in all states except Mississippi and Minnesota. Through all four quarters of 2013, real GDP grew steadily in 24 states.

The deficit decreased to 2.3% of current-dollar gross domestic product from 2.4% in the first quarter. The decrease in the current-account deficit was largely due to a decrease in the deficit on secondary income. In addition, the surpluses on services and primary income increased. These changes were partly offset by an increase in the deficit on goods. In the second quarter, goods exports increased to $408.8 billion from $399.5 billion, a 2.3% increase. Exports increased in five of the six major general-merchandise end-use categories. In the second quarter, exports to Canada increased after decreasing a similar amount in the first quarter.

However, there is considerable uncertainty in the phosphorus load-bloom relationship, because of other biophysical factors that influence bloom size, and because the observed bloom size is not necessarily the true bloom size, owing to measurement error. In this study, we address these uncertainties by relating late-summer bloom observations to spring phosphorus load within a Bayesian modeling framework. This flexible framework allows us to evaluate three different forms of the load-bloom relationship, each with a particular combination of statistical error distribution and response transformation. We find that a novel implementation of a gamma error distribution, along with an untransformed response, results in a model with relatively high predictive skill and realistic uncertainty characterization, when compared to models based on more common statistical formulations. Our results also underscore the benefits of a hierarchical approach that enables assimilation of multiple sets of bloom observations within the calibration processes, allowing for more thorough uncertainty quantification and explicit differentiation between measurement and model error. Finally, in addition to phosphorus loading, the model includes a temporal trend component indicating that Lake Erie has become increasingly susceptible to large cyanobacteria blooms over the study period (2002-2013). Results suggest that current phosphorus loading targets will be insufficient for reducing the intensity of cyanobacteria blooms to desired levels, so long as the lake remains in a heightened state of bloom susceptibility.

Methods Composite disks were prepared using zirconia hybridized ACP fillers (0.4 mass fraction) and photo-activated Bis-GMA/TEGDMA resin (0.6 mass fraction). We performed an investigation of the solution-mediated ACP-to-apatite conversion mechanism in controlled acidic aqueous environment with in situ ultra-small angle X-ray scattering based coherent X-ray photon correlation spectroscopy and ex situ X-ray diffraction, as well as other complementary techniques. Results We established that the ACP-to-apatite conversion in ACP composites is a two-step process, owing to the sensitivity to local structural changes provided by coherent X-rays. Initially, ACP undergoes a local microstructural rearrangement without losing its amorphous character. We established the catalytic role of the acid and found the time scale of this rearrangement strongly depends on the pH of the solution, which agrees with previous findings about ACP without the polymer matrix being present. In the second step, ACP is converted to an apatitic form with the crystallinity of the formed crystallites being poor. Separately, we also confirmed that in the regular Zr-modified ACP the rate of ACP conversion to hydroxyapatite is slowed significantly compared to unmodified ACP, which is beneficial for targeted slow release of functional calcium and phosphate ions from dental composite materials. Significance For the first time, we were able to follow the complete solution-mediated transition process from ACP to apatite in this class of dental composites in a controlled aqueous environment. A two-step process, suggested previously, was conclusively identified.

Using data from 2008 to 2012, monthly climatologies of sea-air CO (sub 2) fluxes for the Bering Sea shelf area from April to December were calculated, and contributions of physical and biological processes to observed monthly sea-air pCO (sub 2) gradients (Delta pCO (sub 2) ) were investigated. Net efflux of CO (sub 2) was observed during November, December, and April, despite the impact of sea surface cooling on Delta pCO (sub 2) . Although the Bering Sea was believed to be a moderate to strong atmospheric CO (sub 2) sink, we found that autumn and winter CO (sub 2) effluxes balanced 65% of spring and summer CO (sub 2) uptake. Ice cover reduced sea-air CO (sub 2) fluxes in December, April, and May. Our estimate for ice-cover corrected fluxes suggests the mechanical inhibition of CO (sub 2) flux by sea-ice cover has only a small impact on the annual scale (<2%). An important data gap still exists for January to March, the period of peak ice cover and the highest expected retardation of the fluxes. By interpolating between December and April using assumptions of the described autumn and winter conditions, we estimate the Bering Sea shelf area is an annual CO (sub 2) sink of approximately 6.8 Tg C yr (super -1) . With changing climate, we expect warming sea surface temperatures, reduced ice cover, and greater wind speeds with enhanced gas exchange to decrease the size of this CO (sub 2) sink by augmenting conditions favorable for greater wintertime outgassing.

Mullet (Mugil cephalus) were fed once every other day over a period of 16 days for nine toxic feedings, and ciguatoxin activity was assessed over time in blood and seven tissues using the Neuro2a assay. Within 3h of feeding on G. polynesiensis cells, ciguatoxins attained maximal blood concentrations, indicating rapid absorption of toxins into the systemic circulation. The time course for distribution of the estimated total tissue burden of ciguatoxin closely followed the time course for blood toxin levels, indicating a rapid distribution of the ciguatoxins throughout the fish body. The large majority (95%) of the ciguatoxin ingested dose was eliminated from the examined fish tissues 24h after a single toxic meal, indicating little retention potential for ciguatoxin. We found no evidence for ciguatoxin accumulation after nine repeated feedings spaced two days apart, indicating that mullet did not accumulate ciguatoxin. These results provide the first experimental evidence supporting the central tenet of Randall's food chain hypothesis that ciguatoxins enter the food chain by transfer from unicellular algae to herbivorous and detritus-feeding fish. We propose that a time-dependent transformation of oxopene ciguatoxins may be necessary for the concentration of ciguatoxin through higher trophic levels.

EDAB events have been hypothesized to be caused by positive feedback interactions involving differential growth of competing algal species, low grazing mortality rates on EDAB species, and resulting decreases in nutrient inputs from grazer-mediated nutrient cycling as the EDAB event progresses. Here we develop a stoichiometric nutrient-phytoplankton-zooplankton (NPZ) model to test a conceptual positive feedback mechanism linked to increased cell toxicity and resultant decreases in grazing mortality rates in EDAB species under nutrient limitation of growth rate. As our model EDAB alga, we chose the slow-growing, toxic dinoflagellate Karenia brevis, whose toxin levels have been shown to increase with nutrient (nitrogen) limitation of specific growth rate. This species was competed with two high-nutrient adapted, faster-growing diatoms (Thalassiosira pseudonana and Thalassiosira weissflogii) using recently published data for relationships among nutrient (ammonium) concentration, carbon normalized ammonium uptake rates, cellular nitrogen:carbon (N:C) ratios, and specific growth rate. The model results support the proposed positive feedback mechanism for EDAB formation and toxicity. In all cases the toxic bloom was preceded by one or more pre-blooms of fast-growing diatoms, which drew dissolved nutrients to low growth rate-limiting levels, and stimulated the population growth of zooplankton grazers. Low specific grazing rates on the toxic, nutrient-limited EDAB species then promoted the population growth of this species, which further decreased grazing rates, grazing-linked nutrient recycling, nutrient concentrations, and algal specific growth rates. The nutrient limitation of growth rate further increased toxin concentrations in the EDAB algae, which further decreased grazing-linked nutrient recycling rates and nutrient concentrations, and caused an even greater nutrient limitation of growth rate and even higher toxin levels in the EDAB algae. This chain of interactions represented a positive feedback that resulted in the formation of a high-biomass toxic bloom, with low, nutrient-limited specific growth rates and associated high cellular C:N and toxin:C ratios. Together the elevated C:N and toxin:C ratios in the EDAB algae resulted in very high bloom toxicity. The positive feedbacks and resulting bloom formation and toxicity were increased by long water residence times, which increased the relative importance of grazing-linked nutrient recycling to the overall supply of limiting nutrient (N).

Specifically, we report the results of a series of field experiments in tropical environments designed to address the correlation of benthic dinoflagellate abundance on artificial substrate and those on adjacent macrophytes. The data indicated abundance of BHAB dinoflagellates associated with new, artificial substrate was directly related to the overall abundance of BHAB cells on macrophytes in the surrounding environment. There was no difference in sample variability among the natural and artificial substrates. BHAB dinoflagellate abundance on artificial substrates reached equilibrium with the surrounding population within 24h. Calculating cell abundance normalized to surface area of artificial substrate, rather than to the wet weight of macrophytes, eliminates complications related to the mass of different macrophyte species, problems of macrophyte preference by BHAB dinoflagellates and allows data to be compared across studies. The protocols outlined in this study are the first steps to a standardized sampling method for BHAB dinoflagellates that can support a cell-based monitoring program for ciguatera fish poisoning. While this study is primarily concerned with the ciguatera-associated genus Gambierdiscus, we also include data on the abundance of benthic Prorocentrum and Ostreopsis cells.

We examined 35 yr of over 10,000 captures of Hawaiian green turtles (Chelonia mydas) and compared results from skeletochronology studies with mark-recapture records. For 109 turtles that were captured as juveniles and later observed nesting, we estimated maturity age first from skeletochronology-based models of age to length and second by estimating age at first capture using skeletochronology and then adding the time elapsed to first nesting. The second method involving mark-recapture gave younger and less variable age estimates. From these data we developed a scaling rule that calculates that females first bred at 23 yr (95% interval: 16.8-28.1). This result was corroborated by tag returns in the Caribbean and Hawai'i showing that green turtles first nest at 16-20 yr. We validated this approach using life table models, successfully reconstructing four decades (1973-2012) of nesting surveys at East Island, French Frigate Shoals. We then compared our results with observed somatic growth rates, which suggest that nearshore studies may sample an atypical subset of the population that is chronically sedentary and slow growing. When exact life history traits are unknown, we recommend consulting multiple lines of evidence and independently validating proxy studies.

Spectroscopic ellipsometry (SE) was used to determine SAM thicknesses and compare the RPA of HS(CH2)3O(CH2CH2O)6CH3 (1), HS(CH2)3O(CH2CH2O)6H (2), [HS(CH2)3]2CHO(CH2CH2O)6CH3 (3) and [HS(CH2)3]2CHO(CH2CH2O)6H (4), assembled from water. For both substrates, SAM thicknesses for 1 to 4 were found to be comparable indicating SAMs with similar surface coverages and OEO chain order and packing densities. Fibrinogen (Fb), a soluble plasma protein, and rhodopsin (Rd), an integral membrane G-protein coupled receptor, adsorbed to the SAMs of 1, as expected from previous reports, but not to the hydroxy-terminated SAMs of 2 and 4. The methoxy-terminated SAMs of 3 were resistant to Fb but, surprisingly, not to Rd. The stark difference between the adsorption of Rd to the SAMs of 3 and 4 clearly indicate that a hydroxy-terminus of the OEO chain is essential for high RPA of IMPs. The similar thicknesses and high RPA of the SAMs of 2 and 4 show the conditions of protein resistance (screening the underlying substrate, packing densities, SAM order, and conformational mobility of the OEO chains) defined from previous studies on Au are applicable to Pt. In addition, the SAMs of 4, exhibiting the highest resistance to Fb and Rd, were placed in contact with undiluted fetal bovine serum for 2h. Low protein adsorption ( approximately 12.4ng/cm2), obtained under these more challenging conditions, denote a high potential of the SAMs of 4 for various applications requiring the suppression of non-specific protein adsorption.

We describe a method and open source R package agTrend for analysing regional trends of abundance from sites with uneven sample schedules over space and time. 2. The method uses a hierarchical model to augment missing abundance measurements, while accounting for survey methodology changes and variability due to survey replication. A zero-inflated log-normal distribution is used to model abundance (normalized for methodology changes) and a log-normal distribution to model the observed abundance conditional on the true normalized abundance. 3. The proposed method and software are demonstrated with an analysis of regional abundance index trends of Steller sea lions (Eumetopias jubatus) in Alaska. 4. The package will be of most use to ecologists and resource managers interested in estimating regional trends of abundance surveys aggregated over several sites when sites have not been surveyed at concurrent times and hence regional abundance measurements cannot be directly calculated.

The National Emissions Inventory for NO sub(x) from area and mobile sources is projected from 2005 to 2012 and NO sub(x) from point sources is projected from 2010 to 2012, in which we find that NO sub(x) emissions from area, mobile and point sources reduce by 8.1%, 37.8% and 4.1%, respectively. The majority of the NO sub(x) emissions reduction occurs in megacities over the CONtiguous U.S. (CONUS), in which the spatial distribution pattern is generally supported by the NO sub(2) column result retrieved from the GOME-2 satellite data. The CMAQ-predicted NO sub(x) and O sub(3) concentrations using updated NO x emissions were then compared to Air Quality System (AQS) ground observations in order to evaluate the updated NO sub(x) emissions inventory. The comparison showed an improvement in NO sub(x) and O sub(3) predictions over the CONUS. The NO sub(x) bias, in July 2011, for urban, suburban and rural land-use types was reduced by 2.34 ppb, 2.09 ppb and 0.57 ppb, respectively. Meanwhile, the O sub(3) bias is reduced by 0.92 ppb, 1.26 ppb and 1.87 ppb, respectively. However, problems remain in CMAQ for NO sub(x) and O sub(3) simulations despite undertaking this emissions adjustment. For example, the O sub(3) overestimation in CMAQ during the daytime over the CONUS decreases when the NO sub(x) underestimation increases, suggesting that in addition to the NO sub(x) emissions inventory, further study of VOC emissions, NO sub(x) chemical and physical mechanisms as well as meteorology parameters in the NAQFC is necessary.

Selectivity parameterization affects point estimates of management quantities and associated uncertainty, as well as the estimation of other model parameters, such as fishing and natural mortality, growth, recruitment, and spawner-recruit relationships. The choice of biological data (length or age) and selectivity assumptions (length- or age-based) made by assessment analysts can directly impact final estimates of important management quantities. In this paper, Pacific mackerel and Pacific sardine stock assessments based on the integrated age-structured Stock Synthesis model are used in concert with simulation methods to evaluate the influence such decisions have on the quality (bias and precision) of estimates of maximum sustainable yield, current spawning stock biomass, and depletion. Findings from this evaluation indicate that: (1) when age data are used, the selectivity assumption (length- or age-based) was generally less influential and did not impact the quality of derived management quantities; (2) when length data are used, misspecification of selectivity generally produced more variable findings and lower quality estimates for quantities of maximum sustainable yield and current biomass; (3) estimates of depletion were generally more robust and precise, irrespective of the biological data or selectivity assumption used in the model; and (4) formal examination of selectivity as illustrated in this paper is useful for identifying other parameters potentially misspecified in the overall model.

Three hundred (300) cases were identified where the convective boundary layer was quasi-stationary and well mixed for a 2 h period, and q mean, variance, third-order moment, and skewness profiles were derived from the 10 s, 75 m resolution data. These cases span the entire calendar year, and demonstrate that the q variance profiles at the mixed layer (ML) top changes seasonally and is strongly related to the gradient of q across the interfacial layer. The q variance at the top of the ML shows only weak correlations (r<0.3) with sensible heat flux, Deardorff convective velocity scale, and turbulence kinetic energy measured at the surface. The median q skewness profile is most negative at 0.85 z sub(i), zero at approximately z sub(i), and positive above z sub(i), where z sub(i) is the depth of the convective ML. The spread in the q skewness profiles is smallest between 0.95 z sub(i) and z sub(i). The q skewness at altitudes between 0.6 z sub(i) and 1.2 z sub(i) is correlated with the magnitude of the q variance at z sub(i), with increasingly negative values of skewness observed lower down in the ML as the variance at z sub(i) increases, suggesting that in cases with larger variance at z sub(i) there is deeper penetration of the warm, dry free tropospheric air into the ML.

The forecast snowfall ranges are based on percentiles from probability distribution functions that are assumed to be perfectly calibrated. A key feature of the technique is that the snowfall range varies dynamically, with the resultant ranges varying based on the spread of ensemble forecasts at a given forecast projection, for a particular case, for a particular location. Furthermore, this technique allows users to choose their risk tolerance, quantified in terms of the expected false alarm ratio for forecasts of snowfall range. The technique is applied to the 47 March 2013 snowstorm at two different locations (Chicago, Illinois, and Washington, D.C.) to illustrate its use in different locations with different forecast uncertainties. The snowfall range derived from the Weather Prediction Center Probabilistic Winter Precipitation Forecast suite is found to be statistically reliable for the day 1 forecast during the 2013/14 season, providing confidence in the practical applicability of the technique.

If not removed, these contaminants may artificially inflate quantitative precipitation estimates and obscure polarimetric and Doppler signatures of weather. A ground-clutter filter is typically employed to mitigate this contamination and provide less biased meteorological-variable estimates. This paper introduces a novel adaptive filter based on the autocorrelation spectral density, which is capable of mitigating the adverse effects of ground clutter without unnecessarily degrading the quality of the meteorological data. The so-called Clutter Environment Analysis using Adaptive Processing (CLEAN-AP) filter adjusts its suppression characteristics in real time to match dynamic atmospheric environments and meets Next Generation Weather Radar (NEXRAD) clutter-suppression requirements.

This carbon-bromine association was recently attributed to covalent bonding, with organobromine in sinking particulates providing a putative link between sedimentary organobromine and organic matter cycling in surface waters. We hypothesized that phytoplankton detritus, a major precursor of sedimentary organic matter, would be susceptible to bromination through oxidative attack. Through a series of model experiments, we demonstrate incorporation of Br into algal particulate detritus through peroxidative and photochemical mechanisms. Peroxidative bromination was enhanced by addition of exogenous bromoperoxidase, but the enzyme was not required for the reaction. Fenton-like reaction conditions also promoted bromination, especially under solar irradiation, implicating radical mechanisms in the euphotic zone as another abiotic source of brominated particulates. These reactions produced aliphatic and aromatic forms of organobromine, suggesting that lipid- and protein-rich components of algal membranes provide suitable substrates for bromination. Biogenic organobromines in certain genera of phytoplankton also appeared in both aliphatic and aromatic forms. Experimental evidence and samples from oceanic midwater sediment traps imply that the aromatic fraction is more stable than the aliphatic. These experiments establish Br as a versatile oxidant in the transformation of planktonic organic matter through both enzymatic and abiotic mechanisms. Organobromine may serve as a marker of oxidative breakdown of marine organic detritus, with the metastable component providing a short-lived indicator of early-stage oxidation. By altering the stability of aliphatic and aromatic moieties, bromination may affect the availability of organic matter to organisms, with consequences for the preservation and degradation of marine organic carbon.

This study presents the 30-year atmospheric temperature trend derived by one-dimensional variational (1D-Var) data assimilation of Microwave Sounding Unit/Advanced Microwave Sounding Unit-A (MSU/AMSU-A) observations. Firstly, the radiance measurements from MSU on board the early National Oceanic and Atmospheric Administration (NOAA)-6 to NOAA-14 and AMSU-A on board NOAA-15 to -19 have been inter-calibrated to form a fundamental climate data record. A 1D-Var method is then employed to establish the thematic climate data record of atmospheric temperature profiles that are appropriate for climate change study. Verification of the MSU/AMSU-A derived temperature profiles with collocated Global Positioning System radio occultation data confirms a reasonable good accuracy of the derived atmospheric temperature profiles in the troposphere and low stratosphere. Finally, the global climate trend of the atmospheric temperature in clear-sky conditions is deduced, showing not only a global warming in the troposphere and a cooling in the stratosphere, but also a stronger warming in the upper troposphere than in the low troposphere.

In particular, temperature, precipitation, and El Nino/La Nina anomalies from 1901 to 2013 were studied. In the southern United States, anomalously cold seasonal temperatures were found to be more closely linked to severe snowstorm development than in the northern United States. The conditional probability of occurrence of one or more severe snowstorms in seasons that are colder than average is 80% or greater in regions of the southern United States, which was found to be statistically significant, while it is as low as 35% when seasonal temperatures are warmer than average. This compares with unconditional probabilities of 55%-60%. For seasons that are wetter (drier) than average, severe snowstorm frequency is significantly greater (less) in the Northern Plains region. An analysis of the seasonal timing of severe snowstorm occurrence found they are not occurring as late in the season in recent decades in the warmest climate regions when compared to the previous 75 years. Since 1977, the median date of occurrence in the last half of the cold season is six or more days earlier in the Southeast, South, and Ohio Valley regions than earlier in the twentieth century. ENSO conditions also were found to have a strong influence on the occurrence of the top 100 snowstorms in the Northeast and Southeast regions.

Rain gauges provide a direct measure of precipitation at a point, which is generally more accurate than remotely sensed observations from radar and satellite. However, high-quality, accurate precipitation gauges are expensive to maintain, and their distributions are too sparse to capture gradients of convective precipitation that may produce flash floods. Weather radars provide precipitation observations with significantly higher resolutions than rain gauge networks, although the radar reflectivity is an indirect measure of precipitation and radar-derived QPEs are subject to errors in reflectivityrain rate (ZR) relationships. Further, radar observations are prone to blockages in complex terrain, which often result in a poor sampling of orographically enhanced precipitation. The current study aims at a synergistic approach to QPE by combining radar, rain gauge, and an orographic precipitation climatology. In the merged QPE, radar data depict high-resolution spatial distributions of the precipitation and rain gauges provide accurate precipitation measurements that correct potential biases in the radar QPE. The climatology provides a high-resolution background of the spatial precipitation distribution in the complex terrain where radar coverage is limited or nonexistent. The merging algorithm was tested on heavy precipitation events in different areas of the United States and provided a superior QPE to the individual components. The new QPE algorithm is fully automated and can be easily implemented in an operational system.

Part II: Sensitivity of Modeled Precipitation to Terrain Height and Atmospheric River Orientation AN - 1611634021; 20792150 AB - This manuscript documents numerical modeling experiments based on a January 2010 atmospheric river (AR) event that caused extreme precipitation in Arizona. The control experiment (CNTL), using the Weather Research and Forecasting (WRF) Model with 3-km grid spacing, agrees well with observations. Sensitivity experiments in which 1) model grid spacing decreases sequentially from 81 to 3 km and 2) upstream terrain is elevated are used to assess the sensitivity of interior precipitation amounts and horizontal water vapor fluxes to model grid resolution and height of Baja California terrain. The drying ratio, a measure of airmass drying after passage across terrain, increases with Bajas terrain height and decreases with coarsened grid spacing. Subsequently, precipitation across Arizona decreases as the Baja terrain height increases, although it changes little with coarsened grid spacing. Northern Bajas drying ratio is much larger than that of southern Baja. Thus, ARs with a southerly orientation, with water vapor transports that can pass south of the higher mountains of northern Baja and then cross the Gulf of California, can produce large precipitation amounts in Arizona. Further experiments are performed using a linear model (LM) of orographic precipitation for a central-Arizona-focused subdomain. The actual incidence angle of the AR (211DG) is close to the optimum angle for large region-mean precipitation. Changes in region-mean precipitation amounts are small (6%) owing to AR angle changes; however, much larger changes in basin-mean precipitation of up to 33% occur within the range of physically plausible AR angles tested. Larger LM precipitation sensitivity is seen with the Baja-terrain-modification experiments than with AR-angle modification.

The data were fit best with a dodecamer (dimer of hexamers). The 12 monomers were linked together by the B/C domains, and the adenosine triphosphatase (AAA+) catalytic regions were found to be freely movable in the full-length dodecamer both in the presence and absence of Mg super(2+) and 50-meric single-stranded DNA (ssDNA). In particular, the SANS data and molecular modeling indicate that all 12 AAA+ domains in the dodecamer lie approximately the same distance from the axis of the molecule, but the positions of the helix-turn-helix region at the C-terminus of each monomer differ. In addition, the A domain at the N-terminus of each monomer is tucked up next to the AAA+ domain for all 12 monomers of the dodecamer. Finally, binding of ssDNA does not lock the AAA+ domains in any specific position, which leaves them with the flexibility to move both for helicase function and for binding along the ssDNA.

Sampling occurred along a series of transects across the shelf between Crescent City, California (Lat. 41 degree 54.0'), and Newport, Oregon (Lat. 44 degree 39.0'), in 2002, and off Willapa Bay, Washington (Lat. 46 degree 40.0'), and the Columbia River, Oregon (Lat. 46 degree 10.0'), in 2006. Species composition varied both years with distance from shore, but the predominant species were darkblotched (Sebastes crameri), canary (S. pinniger), yellowtail (2006 only; S. flavidus), and widow (S. entomelas) rockfishes. Stomach content analysis revealed that darkblotched rockfish had highly variable diets, and canary, yellowtail, and widow rockfishes exhibited a high degree of overlap in 2006. Multivariate analysis showed significant differences in diet based on distance from shore where caught, fish size, and species. Stable isotope analysis indicated that all species were feeding at about the same trophic level within each year, with a 1.5 ppt difference in delta super(15)N between years and regions. The difference in delta super(15)N values may indicate a greater contribution of mesotrophic zooplankton such as euphausiids, hyperiid amphipods, and chaetognaths to fish diets in 2006. Depleted super(13)C values were indicative of diets based on primary production from a more offshore origin, suggesting that these rockfish had previously inhabited offshore waters. These results add to our understanding of some of the important environmental factors that affect young-of-the-year rockfishes during their pelagic phase.

Evaluation of sensitive marine and estuarine species is essential for the development of toxicity testing and risk-assessment protocols. Two estuarine crustacean species, Americamysis bahia (mysids) and Palaemonetes pugio (grass shrimp), were tested with the commonly used pyrethroid compounds, lambda-cyhalothrin, permethrin, cypermethrin, deltamethrin, and phenothrin. Sensitivities of adult and larval grass shrimp and 7-day-old mysids were compared using standard 96-h LC sub(50) bioassay protocols. Adult and larval grass shrimp were more sensitive than the mysids to all the pyrethroids tested. Larval grass shrimp were approximately 18-fold more sensitive to lambda-cyhalothrin than the mysids. Larval grass shrimp were similar in sensitivity to adult grass shrimp for cypermethrin, deltamethrin, and phenothrin, but larvae were approximately twice as sensitive to lambda-cyhalothrin and permethrin as adult shrimp. Acute toxicity to estuarine crustaceans occurred at low nanogram per liter concentrations of some pyrethroids, illustrating the need for careful regulation of the use of pyrethroid compounds in the coastal zone.

AN - 1554472211; 25033243 AB - Domoic acid is an algal-derived seafood toxin that functions as a glutamate agonist and exerts excitotoxicity via overstimulation of glutamate receptors (AMPA, NMDA) in the central nervous system (CNS). At high (symptomatic) doses, domoic acid is well-known to cause seizures, brain lesions and memory loss; however, a significant knowledge gap exists regarding the health impacts of repeated low-level (asymptomatic) exposure. Here, we investigated the impacts of low-level repetitive domoic acid exposure on gene transcription and mitochondrial function in the vertebrate CNS using a zebrafish model in order to: (1) identify transcriptional biomarkers of exposure; and (2) examine potential pathophysiology that may occur in the absence of overt excitotoxic symptoms. We found that transcription of genes related to neurological function and development were significantly altered, and that asymptomatic exposure impaired mitochondrial function. Interestingly, the transcriptome response was highly variable across the exposure duration (36 weeks), with little to no overlap of specific genes across the six exposure time points (2, 6, 12, 18, 24, and 36 weeks). Moreover, there were no apparent similarities at any time point with the gene transcriptome profile exhibited by the glud1 mouse model of chronic moderate excess glutamate release. These results suggest that although the fundamental mechanisms of toxicity may be similar, gene transcriptome responses to domoic acid exposure do not extrapolate well between different exposure durations. However, the observed impairment of mitochondrial function based on respiration rates and mitochondrial protein content suggests that repetitive low-level exposure does have fundamental cellular level impacts that could contribute to chronic health consequences.

AN - 1553316561; 25009960 AB - Sequestering semi-polar compounds can be difficult with low-density polyethylene (LDPE), but those pollutants may be more efficiently absorbed using silicone. In this work, optimized methods for cleaning, infusing reference standards, and polymer extraction are reported along with field comparisons of several silicone materials for polycyclic aromatic hydrocarbons (PAHs) and pesticides. In a final field demonstration, the most optimal silicone material is coupled with LDPE in a large-scale study to examine PAHs in addition to oxygenated-PAHs (OPAHs) at a Superfund site. OPAHs exemplify a sensitive range of chemical properties to compare polymers (log Kow 0.2-5.3), and transformation products of commonly studied parent PAHs. On average, while polymer concentrations differed nearly 7-fold, water-calculated values were more similar (about 3.5-fold or less) for both PAHs (17) and OPAHs (7). Individual water concentrations of OPAHs differed dramatically between silicone and LDPE, highlighting the advantages of choosing appropriate polymers and optimized methods for pollutant monitoring.

AN - 1548633253; 25048883 AB - Bifenthrin is a widely used synthetic pyrethroid insecticide that is often applied to crops, turf, and residential structures for the control of insects. Like other insecticides, bifenthrin has the potential to contaminate bodies of water that are adjacent to the application site via spray drift and runoff during storm events. The objective of this study was to examine the lethal and sublethal effects of bifenthrin on grass shrimp, Palaemonetes pugio, and sheepshead minnow, Cyprinodon variegatus in a 28 d mesocosm experiment under estuarine conditions. Endpoints included mortality and growth and the oxidative stress biomarkers of lipid peroxidation, glutathione, and catalase. In the mesocosm experiment, 24 h and 96 h caged shrimp LC50s were 0.061 and 0.051 μg L(-1), respectively. The uncaged grass shrimp 28 d LC50 was 0.062 μg L(-1). Fifty percent mortality was not reached in the uncaged sheepshead minnow. Bifenthrin did not have a significant effect on the growth of the shrimp, but there was an increasing impact on fish growth. However, it is uncertain as to whether this pattern is a direct effect of the chemical or if it is due to increased food availability resulting from mortality in prey species. The oxidative stress assays were largely inconclusive. Bifenthrin was eliminated rapidly from the water column and readily partitioned to sediments.

During this post-World War II era, many new technologies were emerging for sampling the ocean and atmosphere and for mapping deep-ocean topography. Yet fundamental descriptive work still remained to be done on oceanic and atmospheric circulation, marine geology, and biological and ecological variability in the Indian Ocean.

AN - 1566410011; 25254650 AB - There is a critical need for standard approaches to assess, report and compare the technical performance of genome-scale differential gene expression experiments. Here we assess technical performance with a proposed standard 'dashboard' of metrics derived from analysis of external spike-in RNA control ratio mixtures. These control ratio mixtures with defined abundance ratios enable assessment of diagnostic performance of differentially expressed transcript lists, limit of detection of ratio (LODR) estimates and expression ratio variability and measurement bias. The performance metrics suite is applicable to analysis of a typical experiment, and here we also apply these metrics to evaluate technical performance among laboratories. An interlaboratory study using identical samples shared among 12 laboratories with three different measurement processes demonstrates generally consistent diagnostic power across 11 laboratories. Ratio measurement variability and bias are also comparable among laboratories for the same measurement process. We observe different biases for measurement processes using different mRNA-enrichment protocols.

However, the instrumental records on which these estimates are based are insufficiently long to determine whether such trends exceed preindustrial limits. In the California Current, a 576-year reconstruction of climate variables associated with winter upwelling indicates that variability increased over the latter 20th century to levels equaled only twice during the past 600 years. This modern trend in variance may be unique, because it appears to be driven by an unprecedented succession of extreme, downwelling-favorable, winter climate conditions that profoundly reduce productivity for marine predators of commercial and conservation interest.

AN - 1674681268; 16256 AB - PURPOSE: The development of a National Marine Fisheries Service (NMFS) policy direction to guide distribution of Mitchell Act funds and inform future review of individual Columbia River basin fish hatchery programs under the Endangered Species Act is proposed. Congress enacted the Mitchell Act in 1938 for the conservation of anadromous fishery resources in the Columbia River basin and has continued to appropriate Mitchell Act funds on an annual basis since 1946. These funds have been used to support research, improve fish passage, install screens on water diversions, and build and operate more than 20 salmon and steelhead hatchery facilities. For each of the past 10 years, hatchery operation funding has been between $11 million and $16 million. Historically, hatchery production levels have been as high as 128.6 million juvenile fish annually, but these levels have been substantially reduced as inflation, maintenance, and other costs have eroded the amount of funding available for fish production. At the same time, NMFS listed eight evolutionarily significant units (ESUs) of salmon and five distinct population segments (DPSs) of steelhead in the Columbia River basin under the ESA and cited the adverse effects of hatchery operations as one of the factors for the decline of most of the listed ESUs/DSPs. Policy alternatives are designed to reduce or minimize adverse effects of hatchery operations on natural-origin salmon and steelhead populations, while hatchery operators continue to pursue not only the conservation or harvest goals that currently apply to each hatchery program, but also different or additional conservation and harvest goals as identified within the alternatives. It is anticipated that the alternative selected after completion of this EIS process would be applicable for 10 years. Five alternatives are analyzed in this final EIS. The No Action Alternative (Alternative A) would perpetuate current conditions. Alternative 2 would eliminate Mitchell Act funding and Mitchell Act-funded hatchery programs would be closed. Non-Mitchell programs would be steered toward intermediate performance goals regarding hatchery influence on the spawning grounds and the influence of wild fish in hatcheries. Under Alternative 3, the intermediate performance goal would be applied to all Columbia River basin hatchery programs and overall production levels would be reduced and conservation hatchery programs would be operated at a level determined by conservation need, with hatchery-origin production diminishing as natural-origin production increases. Alternatives 4 and 5 would aim for stronger performance goals for hatcheries in the Interior Columbia River recovery domain above Bonneville Dam and the Willamette/Lower Columbia River recovery domain below Bonneville Dam, respectively. Both envision new conservation and harvest hatchery initiatives and would implement a further winnowing of hatchery strays from the spawning grounds and strengthening of wild, native influence in hatcheries. POSITIVE IMPACTS: Implementation would provide a comprehensive foundation for NOAA Fisheries decision-making under the Endangered Species and Mitchell acts. Stronger performance goals would reduce negative impacts of hatchery programs on natural-origin salmon and steelhead populations. NEGATIVE IMPACTS: Natural-origin salmon and steelhead would continue to be at risk from hatchery facility failure and from water intake and effluent discharge effects. Under the action alternatives, commercial, recreational, and tribal fishing harvest would decline; tribal revenues would decline under all but one of the action alternatives.

AN - 1672869432; 16249 AB - PURPOSE: The Washington Department of Natural Resources proposes incidental take authorization for its activities on state owned aquatic lands. Washington DNR authorizes and conducts activities on approximately 2.7 million acres of state-owned aquatic lands that, while otherwise legal, might result in incidental take of species listed as threatened or endangered under the ESA. This draft EIS analyzes a no-action alternative and two action alternatives. Under the No-action Alternative, Washington DNR would manage requests for uses of state-owned aquatic lands on a site-by-site basis. Under Alternative 2, the Proposed Action, each of the Services would issue an ITP to Washington DNR authorizing the incidental take of the covered species by covered activities through the implementation of the ITP, including the Aquatic Lands HCP. The ITPs would be valid for 50 years. The Operating Conservation Program for the Aquatic Lands HCP would define how Washington DNR implements the mitigation sequence of avoidance, minimization, and compensation for unavoidable impacts of aquatic lands uses authorized by Washington DNR. The HCP Operating Conservation Program would include measures designed to avoid, minimize, and mitigate, to the maximum extent practicable, for incidental take associated with Washington DNRs management of state-owned aquatic lands. In addition, Washington DNR would implement an adaptive management program and would follow management practices that contribute to meeting the goals and objectives of the HCP. The HCP Operating Conservation Program would also incorporate additional commitments by Washington DNR, including programs to restore or protect aquatic habitat and implement management practices that contribute to meeting the goals and objectives of the HCP. Under Alternative 3, the Services would issue ITPs only for those proposed covered activities and species that occur on state-owned lands in marine areas. The HCP would not cover the Columbia spotted frog, Oregon spotted frog, northern leopard frog, western toad, western pond turtle, or black tern because in Washington State, these species occur only in freshwater habitats. All other species identified in Table ES-1 would be covered. Washington DNR would implement all of the elements of the HCP Operating Conservation Program, but in marine areas only. Washington DNRs ongoing habitat protection and restoration programs and actions would be applied toward compensation for remaining unavoidable impacts from authorized uses in marine and estuarine waters only. In freshwater areas, Washington DNR would manage state-owned aquatic lands as described for Alternative 1, No Action. POSITIVE IMPACTS: Washington DNRs emphasis on retention and acquisition of lands most in need of protection may lead to greater retention and acquisition of lands in nearshore and littoral areas that provide habitat for species proposed for ITP coverage through the Aquatic Lands HCP. Implementation of the HCP Operating Conservation Program would be expected to reduce the risk of adverse effects on species proposed for ITP coverage. NEGATIVE IMPACTS: The implementation of measures that reduce the visual impacts of some aquatic land uses may render some waterfront properties more desirable for development as residential areas, park and recreation facilities, restaurants, or other businesses, possibly leading to an increase in such uses. Some elements of the programfor example, the requirement to remove derelict structurescould result in an increased risk of adverse effects on cultural resources. Implementation of measures that place restrictions on the location and/or operation of shellfish aquaculture facilities, log handling facilities, and overwater structures would reduce the amount of aquatic areas available for private use.

AN - 1672869425; 16248 AB - PURPOSE: An annual catch limit for red snapper in the Gulf of Mexico is proposed. The Gulf of Mexico (Gulf) red snapper stock is overfished and currently under a rebuilding plan. As the stock has recovered, both commercial and recreational quotas have been allowed to increase per the rebuilding plan. The commercial sector has been managed under an individual fishing quota (IFQ) program since 2007 and landings have stayed below the commercial quota as each IFQ allocation holder is strictly monitored to ensure they do not land more fish than pounds allocated to them through the program. The recreational sector, which has experienced quota overages and shorter seasons recently, is managed under a quota, bag and size limits, and closed seasons. To minimize the chances of the recreational sector exceeding its quota, the Gulf of Mexico Fishery Management Council (Council) asked the National Marine Fisheries Service (NMFS) to put in place an annual catch target (ACT) as an accountability measure for the 2014 fishing season. This draft EIS analyzes three actions with a total of 15 alternatives. Action 1 is the establishment of distinct components with the recreational sector. Action 1 would consider the establishment of a federal for-hire and private angling components within the recreational sector. Alternatives include: no action (Alternative 1) where the recreational sector would not be divided into two components; Preferred Alternative 2 would establish the two components where all federally permitted for-hire vessels would be added to the federal for-hire component; and Alternatives 3 and 4 would establish the two components where federal for-hire operators may opt into the federal for-hire component. Alternatives 3 and 4 differ in that the endorsement used to identify which for-hire vessels are in the for-hire component are fully transferable under Alternative 3 and not transferable under Alternative 4. Alternatives 3 and 4 also have options for the frequency that vessel operators may choose to opt in or out of the for-hire component of just once (option a), every year (option b), every 3 years (option c), and every 5 years (option d). Action 2 would set the allocation between the federal for-hire and private angling components. The Council selected Action 1, Alternative 2 as preferred, which establishes a mandatory sector separation. As a result, they removed two actions that would have adjusted the allocation for vessels opting out of the federal-for hire component as allowed for under Action 1, Alternatives 3 and 4. Action 2 considers a variety of allocations between the federal for-hire and private angling components and the allocations would be applied to both the recreational quota and recreational ACT. These alternatives are: (1) Alternative 1 maintain the current structure of the recreational sector; (2) Alternative 2 allocation based on average landings between 1986 and 2013; (3) Alternative 3 allocation based on average landings between 1991 and 2013; (4) Alternative 4 allocation based on average landings between 1996 and 2013; (5) Alternative 5 - allocation based on average landings between 2001 and 2013; (6) Alternative 6 allocation based on average landings between 2006 and 2013; (7) Preferred Alternative 7 allocation based on 50% of the average percentages landed by each component between 1986 and 2013 and 50% of the average percentages landed by each component between 2006 and 2013; (8) Alternative 8 allocation based on percentages of the quota landed by each component between 2011 and 2013; and (9) Alternative 9 allocation based on average landings between 1986 and 2003. Action 3 considers how the recreational season closure provision would be implemented given the two components. No action (Alternative 1) would maintain the current recreational red snapper season closure provisions where the recreational red snapper ACT would be used to determine the recreational red snapper season length. Preferred Alternative 2 would establish separate red snapper season closure provisions for the federal for-hire and private angling components. The component red snapper ACTs would be used to determine the respective components federal red snapper season length. The ACTs, reduced from the respective annual catch limits (ACLs), are considered an accountability measures and reduce the probability that a component would exceed its ACL. Note that this action is restricted to two alternatives. Because the Council sees sector separation as a first step being able to tailor management measures for each component in future actions, the Council limited the scope of Action 3 to season closure provisions based on a June 1 season opening to reduce confusion in the recreational sector while long-term, component-specific measures are developed. POSITIVE IMPACTS: The proposed action would prevent overfishing while achieving the optimum yield, particularly with respect to recreational opportunities, while rebuilding the red snapper stock. NEGATIVE IMPACTS: The cumulative effects of allocating recreational red snapper between the for-hire and private-angling components on the biophysical environment is likely neutral because it should not have much effect on overall fishing effort. For the socioeconomic environment, depending on the component, some effects would likely be positive and some negative depending on who the allocation favors. However, short-term negative impacts on the fisheries socioeconomic environment may occur due to the need to limit directed harvest and reduce bycatch mortality. These negative impacts can be minimized within the recreational sector by using combinations of bag limits, size limits, and closed seasons and that these measures can be tailored to meet the needs of each sector component.

Preparation date: September 5, 2014 N1 - Last updated - 2015-04-14 ER - TY - RPRT T1 - AMENDMENT 7 TO THE 2006 CONSOLIDATED ATLANTIC HIGHLY MIGRATORY SPECIES FISHERY MANAGEMENT PLAN. AN - 1672869424; 16246 AB - PURPOSE: Amendment 7 to the 2006 Consolidated Atlantic Highly Migratory Species (HMS) Fishery Management Plan (FMP) is proposed to ensure sustainable management of bluefin tuna. Under the 2006 FMP, the bluefin fishery is quota-managed. An annual U.S. bluefin quota is established by the International Commission for the Conservation of Atlantic Tunas (ICCAT) and allocated domestically among seven domestic quota categories. In 2011, during the annual bluefin quota specifications process, it became apparent that the adjusted quota for 2011 was insufficient to account for anticipated 2011 dead discards while also providing full base allocations to the directed fishing categories per the established allocation percentages. This final EIS considers a range of alternative management measures to eliminate overfishing and further the rebuilding of western bluefin stock. The preferred alternatives under Amendment 7 would reallocate the U.S. bluefin tuna quota among domestic fishing categories. The rule would also implement several actions applicable to the pelagic longline fishery, including: individual bluefin quotas (IBQs); two new gear restricted areas, access to current closed areas based on performance criteria; closure of the pelagic longline fishery when annual bluefin tuna quota is reached; elimination of target catch requirements associated with retention of incidental bluefin tuna in the pelagic longline fishery; mandatory retention of legalsized bluefin tuna caught as bycatch; expanded monitoring requirements, including electronic monitoring via cameras and bluefin tuna catch reporting via vessel monitoring system (VMS); and transiting provisions for pelagic and bottom longline vessels. The proposed rule would also require VMS use and reporting by the purse seine category; change the start date of the purse seine category to June 1; expand automated catch reporting system use to the general and harpoon categories; provide additional flexibilities for inseason adjustment of the general category quota and harpoon category retention limits; and allocate a portion of the angling category Trophy South subquota to the Gulf of Mexico. Finally, it would adopt several measures not directly related to bluefin tuna management, including implementing a U.S. North Atlantic albacore tuna quota; modifying rules regarding permit category changes; and implementing minor changes in the HMS regulations for administrative or clarification purposes. This final EIS also includes broad descriptions and general analyses of management tools that could be implemented in the future via subsequent proposed rulemaking. POSITIVE IMPACTS: The proposed measures would reduce dead discards; provide strong incentives to avoid bluefin bycatch in the longline fishery; substantially increase the accountability of the quota system and improve quota management overall by reducing the risk that dead discards and landings will exceed the total U.S. quota; and enhance reporting through new requirements and incentives. These measures would directly support the goals of reducing overfishing, rebuilding the western bluefin stock, and achieving optimum yield by ensuring that the fishery continues to be managed within the ICCAT-approved total allowable catch. NEGATIVE IMPACTS: Vessels that have a history of avoiding bluefin tuna, and continue to avoid bluefin tuna, would experience moderate socioeconomic impacts, with the principal impact being the costs associated with electronic monitoring and VMS reporting. Pelagic longline vessels that have a history of interacting with many bluefin, and continue to interact with bluefin in the future, would experience major cumulative socioeconomic impacts due to the combined impacts of the IBQ, the gear restricted areas, and the enhanced reporting measures. IBQ allocations are likely to most severely constrain the fishing behavior of approximately 24 percent of these vessels. For the purse seine category, the cumulative economic impacts would be minor. For the general, harpoon, charter/headboat, and angling categories, the cumulative economic impacts would be neutral or minor due to the modifications to the rules that dictate how the category specific quota is managed, and the enhanced reporting requirements.

Preparation date: September 5, 2014 N1 - Last updated - 2015-04-14 ER - TY - RPRT T1 - DOWNTOWN SAN FRANCISCO FERRY TERMINAL EXPANSION PROJECT, SAN FRANCISCO, CALIFORNIA. AN - 1672869423; 16243 AB - PURPOSE: The expansion and improvement of the existing Ferry Terminal at the Ferry Building in downtown San Francisco, California are proposed. The Ferry Terminal is in the northeastern section of San Francisco, situated at the foot of Market Street at the Embarcadero. The project area encompasses property managed in the public trust by the Port of San Francisco from the south side of Pier 1 to the north side of Pier 14, and from the Embarcadero Promenade to San Francisco Bay. The project area includes the Ferry Building, the Ferry Plaza, the Agriculture Building, and Pier 2. The project area also includes existing water transit facilities (Gates B, C, D, and E), a variety of commercial uses, and public open spaces. The proposed project builds on previous planning efforts and projects implemented by the San Francisco Bay Area Water Emergency Transportation Authority (WETA) and the Port. The implementation and operations plan adopted by WETA in 2003 called for a system-wide expansion of water transit service in the Bay Area and identified new routes that would be developed over a 20-year period. Water transit provides a viable alternative for transporting people around the region when unexpected and long-term disruption renders other components of the regional transportation system inoperable. In 2035, the Ferry Terminal is projected to serve approximately 32,000 water transit passengers, an increase of 300 percent over current ridership levels of 11,200 passengers, accounting for existing services between San Francisco and Alameda, Oakland, and Vallejo, as well as future planned water transit services between San Francisco and Antioch, Berkeley, Martinez, Hercules, Redwood City, Richmond, and Treasure Island. The projected ridership increases cannot be adequately accommodated at the Ferry Terminal because of current infrastructure, circulation, and operating deficiencies. This final EIS considers the proposed expansion and a No Action Alternative. The proposed project would include construction of three new gates and overwater berthing facilities, in addition to supportive landside improvements, such as additional passenger waiting and queuing area, and circulation improvements. The new gates and other improvements would be designed to accommodate future planned water transit services, as well as emergency operation needs. Construction is scheduled to commence as early as 2014 and be completed by 2020. POSITIVE IMPACTS: Implementation would support WETAs projected increase in water transit ridership and related vessel arrivals and departures from the Ferry Terminal. Expanded water transit would provide a viable alternative mode of transportation that accommodates projected increases in transbay trips, and helps alleviate congestion over the San Francisco Bay Bridge and through the San Francisco Bay Area Rapid Transit transbay tube. NEGATIVE IMPACTS: The proposed project would result in a net increase of 345 square feet of fill in bottom habitat; this small loss of benthic habitat would be considered negligible in this environment. Construction and maintenance dredging could impact special-status and commercially valuable marine species, including their habitats. Demolition activities would require the removal and temporary storage of piles that contain potentially hazardous substances. General construction noise and pile-driving activities would adversely impact noise-sensitive receivers in the project vicinity. Increases in pedestrian circulation associated with the project would result in substantial overcrowding for three study area crosswalks.

The hypotheses were tested using salmon density measurements and a condition anomaly calculated from residuals of the length-weight linear regression based on 5,536 subyearlings collected from brackish estuarine and tidal freshwater (TFW) habitats. We captured Chinook Salmon at all temperatures encountered (4.2-23.5 degree C). In the TFW zone, densities were highest at optimal temperatures and lowest at suboptimal and supraoptimal temperatures; in the estuary, density did not differ among temperature regimes. Fish condition was lowest in winter, when temperatures were suboptimal, and highest in summer, when temperatures were supraoptimal. Pairwise comparisons of fish condition between periods of optimal temperature (spring) and supraoptimal or stressful temperature (summer) showed little change in the estuary but a large, positive increase with temperature in the TFW zone. Similarly, we examined seasonal differences in the condition of 50-60-mm fry and again found condition to be lowest in winter and highest in summer. Finally, using genetic information, we identified stock-specific differences in migration timing and concluded that most large yearlings and many subyearlings migrated in late winter or spring and therefore were never exposed to high temperatures. Other prevalent stocks persisted in the estuary during periods of elevated temperature; however, the condition of those fish also tended to be higher or neutral in summer than in spring. High temperatures appeared to influence migration timing, as evidenced by reduced density in TFW reaches during summer. However, we found little support for the hypothesis that condition of juvenile Chinook Salmon is reduced during periods of high water temperature in the lower Columbia River and estuary.

Human serum albumin (HSA1) was selected for this purpose owing to its ubiquity, high level of characterization and availability of digest data. The underlying experimental data consisted of similar to 3000 one-dimensional LC-ESI-MS/MS runs with ion-trap fragmentation. In order to generate a wide range of peptides, studies covered a broad set of instrument and digestion conditions using multiple sources of HSA and trypsin. Computer methods were developed to enable the reliable identification and reference spectrum extraction of all peptide ions identifiable by current sequence search methods. This process made use of both MS2 (tandem) spectra and MS1 (electrospray) data. Identified spectra were generated for 2918 different peptide ions, using a variety of manually-validated filters to ensure spectrum quality and identification reliability. The resulting library was composed of 10% conventional tryptic and 29% semitryptic peptide ions, along with 42% tryptic peptide ions with known or unknown modifications, which included both analytical artifacts and post-translational modifications (PTMs) present in the original HSA. The remaining 19% contained unexpected missed-cleavages or were under/over alkylated. The methods described can be extended to create equivalent spectral libraries for any target protein. Such libraries have a number of applications in addition to their known advantages of speed and sensitivity, including the ready re-identification of known PTMs, rejection of artifact spectra and a means of assessing sample and digestion quality.

However, the dual origins of deep-sea methane, both chemical and biological, complicate the interpretation of methane observations. Here, we use both the concentration and stable carbon isotopic composition (delta (super 13) C) of dissolved methane to trace hydrothermal plumes and identify the source and behavior of methane at two sites of newly discovered hydrothermal activity on the Central Indian Ridge (11-13 degrees S). At both sites, methane and optical anomalies between 2500 and 3500 m at all stations indicate active hydrothermal discharge. We compared methane concentrations and delta (super 13) C at three stations, two (CTIR110136 and CTIR110208) with the most prominent anomalies at each site, and a third (CTIR110140) with near-background methane values. At stations CTIR110136 and CTIR110208, the concentration and delta (super 13) C of methane in distinct plumes ranged from 3.3 to 42.3 nmol kg (super -1) and -30.0 to -15.4 ppm, respectively, compared to deep-water values of 0.5 to 1.2 nmol kg (super -1) and -35.1 to -28.9 ppm at the station with a near-background distal plume (CTIR110140). delta (super 13) C was highest in the center of the plumes at CTIR110136 (-15.4 ppm) and CTIR110208 (-17.8 ppm). From the plume values we estimate that the delta (super 13) C of methane in the hydrothermal fluids at these stations was approximately -19 ppm and thus the methane was most likely derived from magmatic outgassing or the chemical synthesis of inorganic matter. We used the relationship between delta (super 13) C and methane concentration to examine the behavior of methane at the plume stations. In the CTIR110208 plume, simple physical mixing was likely the major process controlling the methane profile. In the CTIR110136 plume we interpret a more complicated relationship as resulting from microbial oxidation as well as physical mixing. We argue that this difference in methane behavior between the two areas stems from a distinct bathymetric dissimilarity between the two stations. The location of CTIR110208 on the open slope of a ridge allowed rapid plume dispersion and physical mixing, whereas the location of CTIR110136 in a small basin surrounded by wall structures inhibited physical mixing and enhanced microbial oxidation.

The second estimate of real GDP growth was revised up 0.2 percentage point from the advance estimate of 4.0%; the upward revision primarily reflected an upward revision to nonresidential fixed investment and a downward revision to imports that were partly offset by a downward revision to inventory investment. In the first quarter, real GDP decreased 2.1 %. Real GDP turned up in the second quarter, primarily reflecting upturns in exports and in inventory investment, accelerations in consumer spending and in nonresidential fixed investment, and upturns in state and local government spending and in residential fixed investment that were partly offset by an acceleration in imports.

Over the past few decades, summer areal extent has declined over 30%, and all months show statistically significant declining trends. New satellite missions and techniques have greatly expanded information on sea ice thickness, but many uncertainties remain in the satellite data and long-term records are sparse. However, thickness observations and other satellite-derived data indicate a 40% decline in thickness, due in large part to the loss of thicker, older ice cover. The changes in sea ice are happening faster than models have projected. With continued increasing temperatures, summer ice-free conditions are likely sometime in the coming decades, though there are substantial uncertainties in the exact timing and high interannual variability will remain as sea ice decreases. The changes in Arctic sea ice are already having an impact on flora and fauna in the Arctic. Some species will face increasing challenges in the future, while new habitat will open up for other species. The changes are also affecting people living and working in the Arctic. Native communities are facing challenges to their traditional ways of life, while new opportunities open for shipping, fishing, and natural resource extraction. Significant progress has been made in recent years in understanding of Arctic sea ice and its role in climate, the ecosystem, and human activities. However, significant challenges remain in furthering the knowledge of the processes, impacts, and future evolution of the system. Abstract Copyright (2014), American Geophysical Union.

Twenty-kilometer resolution combined meteorological and chemical simulations examine transport pathways, spatial distribution, and quantities of ozone precursors and ozone. Results suggest that due to biomass burning, ozone mixing ratios increase by 28-33 parts per billion by volume in the lower troposphere (850 hecto-Pascals) over the Atlantic Ocean west of Central Africa during June. The inter-hemispheric transport of biomass burning emissions from Central Africa subsides over the Gulf of Guinea with a northward extent of approximately 2-5 degree N. In the lower troposphere, ozone mixing ratio increases decrease from 28 parts per billion by volume in the southern Gulf of Guinea to 2-3 parts per billion by volume on the Gulf of Guinea Coast. There is middle and upper tropospheric ozone enhancement of 6-12 parts per billion over the Equatorial Atlantic Ocean which is the result of convective detrainment of ozone precursors from deep convection on the Gulf of Guinea Coast followed by transport that propagates around a broad anticyclone. The model ozone produced by biomass burning emissions is less than the observed implying that lightning-induced nitrogen oxide emissions, which are not included in this simulation, are a significant tropospheric ozone source for the eastern Equatorial Atlantic Ocean.

One solution to improving these estimates of year-class strength or recruitment is to first develop regional indices representing the spatial and temporal extent of a hypothesized feature influencing a species' recruitment. These covariates should then be integrated within a population model where a variety of model selection techniques may be conducted to test for a reduction in recruitment uncertainty. The best selected model(s) may provide insight for developing hypotheses of mechanisms influencing recruitment. Here we consider the influence of a large-scale oceanographic feature, the North Pacific Polar Front, on recruitment of Alaska sablefish (Anoplopoma fimbria). Our working hypothesis is that advection of oceanic properties along the Polar Front and associated currents plays a key role in shaping the oceanographic climate of Alaskan waters and, hence, the environment that sablefish encounter during their early life history. As a first step in this investigation, we developed time series of sea surface temperature along the Polar Front mean path. We then integrated this data into the recruitment equations of the sablefish assessment base model. Model selection was based on a multistage hypothesis testing procedure combined with cross-validation and a retrospective analysis of prediction error. The impact of the best model was expressed in terms of increased precision of recruitment estimates and proportional changes in female spawning biomass for both current estimates and in future projections. The best model suggested that colder than average wintertime sea surface temperatures in the central North Pacific represent oceanic conditions that create positive recruitment events for sablefish. The incorporation of this index in the sablefish model provided moderate reduction in unexplained recruitment variability and increased future projections of spawning biomass in the medium term. Based on this result, we developed a conceptual model of three mechanisms that in combination form an ocean domain dynamic synergy (ODDS) which influences sablefish survival through the pelagic early life history stage. Successfully incorporating environmental time series into the sablefish assessment could establish a foundation for future ecosystem-based management and allow for more informed and efficient resource allocation to stakeholders.

These models show a response that includes lowering of global average sea surface temperature by 0.1-0.3 K, comparable to the observations. They show enhancement of Arctic ice cover in the years following major volcanic eruptions, with long-lived temperature anomalies extending to the middepth and deep ocean on decadal to centennial timescales. Regional ocean responses vary, although there is some consistent hemispheric asymmetry associated with the hemisphere in which the eruption occurs. Temperature decreases and salinity increases contribute to an increase in the density of surface water and an enhancement in the overturning circulation of the North Atlantic Ocean following these eruptions. The strength of this overturning increase varies considerably from model to model and is correlated with the background variability of overturning in each model. Any cause/effect relationship between eruptions and the phase of El Nino is weak. Abstract Copyright (2014), . American Geophysical Union. All Rights Reserved.

Using a high-resolution ocean general circulation model, we investigate the effect of these two EOFs on changes in warm water volume (WWV), interhemispheric mass transports, and Indonesian Throughflow (ITF). Wind stress anomalies associated with the first EOF produce changes in WWV that are dynamically consistent with the conceptual recharge oscillator paradigm. The ITF is found to heavily damp these WWV changes, reducing their variance by half. Wind stress anomalies associated with the second EOF, which depicts the southward wind shift, are responsible for WWV changes that are of comparable magnitude to those driven by the first mode. The southward wind shift is also responsible for the majority of the observed interhemispheric upper ocean mass exchanges. These winds transfer mass between the Northern and the Southern Hemisphere during El Nino events. Whilst water is transferred in the opposite direction during La Nina events, the magnitude of this exchange is roughly half of that seen during El Nino events. Thus, the discharging of WWV during El Nino events is meridionally asymmetric, while the WWV recharging during a La Nina event is largely symmetric. The inclusion of the southward wind shift is also shown to allow ENSO to exchange mass with much higher latitudes than that allowed by the first EOF alone. Abstract Copyright (2014), .

Three data sets are employed as inputs to the blended analysis: in situ SSS measurements aggregated and quality controlled by NOAA/NODC, and passive microwave (PMW) retrievals from both the National Aeronautics and Space Administration's (NASA) Aquarius/SAC-D and the European Space Agency's (ESA) Soil Moisture-Ocean Salinity (SMOS) satellites. The blended analysis comprises two steps. First, the biases in the satellite retrievals are removed through probability distribution function (PDF) matching against temporally spatially colocated in situ measurements. The blended analysis is then achieved through optimal interpolation (OI), where the analysis for the previous time step is used as the first guess while the in situ measurements and bias-corrected satellite retrievals are employed as the observations to update the first guess. Cross validations illustrate improved quality of the blended analysis, with reduction in bias and random errors over most of the global oceans as compared to the individual inputs. Large uncertainty, however, remains in high-latitude oceans and coastal regions where the in situ networks are sparse and current-generation satellite retrievals have limitations. Our blended SSS analysis shows good agreements with the NODC in situ-based analysis over most of the tropical and subtropical oceans, but large differences are observed for high-latitude oceans and along coasts. In the tropical oceans, the BASS is shown to have coherent variability with precipitation and evaporation associated with the evolution of the El Nino-Southern Oscillation (ENSO).

The distribution of eggs could be predicted using sea-surface temperature, chlorophyll concentration, and eddy kinetic energy (EKE) similarly to previous studies. Eddies alone did not have a significant additional or emergent effect on the probability of capturing eggs beyond these predictors. Rather, mesoscale features (eddies and streamers) entrained water with the appropriate conditions in terms of temperature, chlorophyll, and EKE. These dynamic features moved appropriate spawning habitat for sardine offshore to areas where appropriate habitat otherwise would not exist. Using centroids of predicted sardine habitat, we showed that sardine recruitment success was inversely correlated with distance from shore of predicted sardine habitat centroids. This indicates that offshore transport has a negative effect on sardine recruitment, despite expanding favorable spawning habitat further offshore. Abstract Copyright (2014), .

Evidence from a stated preference study AN - 1627968274; 20928673 AB - The value anglers place on their fishing opportunities is critical information for fully informing marine policy within an economic efficiency framework. In this paper, we use data from a 2007 stated preference survey of anglers to estimate the value of catching Pacific halibut (Hippoglossus stenolepis), Chinook salmon (Oncorhynchus tshawytscha), and coho salmon (Oncorhynchus kisutch) off the coast of Southeast and Southcentral Alaska, the primary regions for saltwater sport fishing in the state. The data support a specification that differentiates between values for fish that are caught and kept, caught and released (due to a bag limit restriction), and potential catch (fish in excess of the number caught but within the bag limit). The results indicate that for single-day marine private boat fishing trips where one species is caught with catches less than or equal to the allowable bag (or take) limit, Southeast Alaska residents had mean values for fishing ranging from $248 to $313 (U.S. dollars), depending upon whether the fish was kept or released. Single-day private boat fishing trips in Southcentral Alaska were valued between $284 and $385 by Alaska residents. Among Alaska residents, mean values for charter fishing trips in Southcentral Alaska were between $228 and $328. Non-residents had much higher total values for the same fishing experiences, likely due to the fact that the trips are both less common and considerably more expensive to participate in given the travel costs to Alaska. Mean trip values ranged from $1849 to $2686 for charter fishing in Southeast Alaska and $1954 to $2819 in Southcentral Alaska. Non-resident and Alaska resident anglers generally had statistically-significant positive values for increases in number of fish caught and kept, potential catch, and fish size.

We find that inclusion of the shortwave continuum in the fixed sea surface temperature case (AM3) results in a similar increase in shortwave absorption and heating rates to that seen for the "benchmark" line-by-line radiative transfer calculations. The surface energy budget adjusts to the inclusion of the shortwave continuum predominantly through a decrease in both surface latent and sensible heat. This leads to a decrease in tropical convection and a subsequent 1% reduction in tropical rainfall. The inclusion of the shortwave continuum in the fully coupled atmosphere-ocean model (CM3) yields similar results, but a smaller overall reduction of 0.5% in tropical rainfall due to global warming of ~0.1K linked to enhanced near-infrared absorption. We also investigated the impact of adding a stronger version of BPS-MTCKD (version 1.1) to the global climate model (GCM). In most cases we found that the GCM responds in a similar manner to both continua but that the strength of the response scales with the level of absorbed shortwave radiation. Global warming experiments were run in both AM3 and CM3. The shortwave continuum was found to cause a 7 to 15% increase in clear-sky global dimming depending upon whether the stronger or weaker continuum version was used. Neither version resulted in a significant change to the climate sensitivity.

Results show that there is a recent significant salinity increase at the core of the salinity minimum at intermediate levels. The main underlying mechanism for this subsurface salinity increase is the lateral advective (gyre) changes due to the Southern Annular Mode variability, which conditions an increased contribution from the Indian Ocean high salinity waters into the Atlantic. The global warming signal has a secondary but complementary contribution. Latitudinal differences at intermediate depth in response to large-scale forcing are in part caused by local variation of westward propagation features, and by compensating contributions of salinity and temperature to density changes.

In the radar receiver, this external radiation produces noise that adds to the receiver internal noise and results in the system noise power varying with the antenna position. If these variations are not captured, they translate into erroneous signal powers because these are computed via subtraction of noise power measurements from the overall power estimates. This may lead to biased meteorological variables at low to moderate signal-to-noise ratios if those are computed using signal power estimates. In dual-polarization radars, this problem is even more pronounced, particularly for correlation coefficient estimates that use noise power measurements from both the horizontal and vertical channels. An alternative is to use estimators that eliminate the need for noise corrections but require sufficient correlation of signals in sample time, which limits their applicability. Therefore, when the use of the latter is inappropriate, the quality of correlation coefficient estimates can be improved by computing them using sufficiently accurate noise powers measured at each antenna position. An effective technique that estimates the noise powers in real time at each scan direction and in parallel with weather data collection has been proposed. Herein, the impacts of such a technique on the estimation of the correlation coefficient are investigated. The results indicate that the use of more accurate noise power estimates can significantly reduce the bias of correlation coefficient estimates, thus visibly improving the correlation coefficient fields. This is expected because the correlation coefficient is computed using noise power measurements from both the horizontal and vertical channels.

However, we find that certain aldehydes undergo loss of H sub(2) followed by reaction with water in the collision cell. This complicates interpretation of tandem mass (MS/MS) spectra and affects multiple reaction monitoring (MRM) results. METHODS 3-Formylchromone and other aldehydes were dissolved in acetonitrile/water/formic acid and studied by ESI-MS to record their MS super(2) and MS super(n) spectra in several mass spectrometers (QqQ, QTOF, ion trap (IT), and Orbitrap HCD). Certain product ions were found to react with water and the rate of reaction was determined in the IT instrument using zero collision energy and variable activation times. Theoretical calculations were performed to help with the interpretation of the fragmentation mechanism. RESULTS Protonated 3-formylchromones and 3-formylcoumarins undergo loss of H sub(2) as a major fragmentation route to yield a ketene cation, which reacts with water to form a protonated carboxylic acid. In general, protonated aldehydes which contain a vicinal group that forms a hydrogen bridge with the formyl group undergo significant loss of H sub(2). Subsequent losses of CO and C sub(3)O are also observed. Theoretical calculations suggest mechanistic details for these losses. CONCLUSIONS Loss of H sub(2) is a major fragmentation channel for protonated 3-formychromones and certain other aldehydes and it is followed by reaction with water to produce a protonated carboxylic acid, which undergoes subsequent fragmentation. This presents a problem for reference libraries and raises concerns about MRM results. Published in 2014. This article is a U.S. Government work and is in the public domain in the USA.

For a given atmospheric temperature condition, the emission and scattering of clouds and precipitation modulate MSU and AMSU-A brightness temperatures. In this study, the effects of the radiation from clouds and precipitation on AMSU-A derived atmospheric temperature trend are assessed using the information from AMSU-A window channels. It is shown that the global mean temperature in the low and middle troposphere has a larger warming rate (about 20-30 % higher) when the cloud-affected radiances are removed from AMSU-A data. It is also shown that the inclusion of cloud-affected radiances in the trend analysis can significantly offset the stratospheric cooling represented by AMSU-A channel 9 over the middle and high latitudes of Northern Hemisphere.

However, differences in life history such as seasonal timing of migration and reproduction, iteroparity versus semelparity, and the extent of natal homing are likely to affect the capacity for expansion and re-colonization by taxa such as alosines, lamprey, and salmonids. We first review some basic life history traits that may affect re-colonization by migratory fishes, and then present selected examples from Atlantic and Pacific basins to illustrate these patterns and their implications for the success of barrier removal as a measure to advance the goal of fish conservation. We conclude that diadromous fishes have the capacity to rapidly re-colonize newly available habitats, though the life history patterns of each species, the proximity to source populations in the same or nearby river systems, and the diversity of habitats available may control the patterns and rates of re-colonization.

General life history and ecology share many common traits including iteroparity, duration of freshwater (0-3 years) and marine (2-5 years) rearing, ocean emigration at relatively large sizes and strong surface orientation compared to other salmonids. Despite parallels in life history and anthropogenic pressures, several differences emerged for these species. First, steelhead have greater life history diversity and a broader geographic distribution. Generally, estuary habitats serve as short-term migration corridors for both species. However, some steelhead populations used lagoon habitat in south-coast watersheds. While both species are epipelagic, Atlantic salmon exhibit more vertical migration. Atlantic salmon tend to follow migratory highways-relatively narrow bands along the coastal shelf, then crossing the Atlantic to feed inshore and in fjords of West Greenland. Conversely, steelhead exit the coastal shelf quickly, dispersing across the Pacific, and rarely use coastal environments. Despite inhabiting rivers in warm dry Mediterranean climates, the extended range and stability of southern steelhead distribution is likely buffered by cool upwelled waters of the California Current. Whereas Atlantic salmon populations are restricted by warmer Northwest Atlantic circulation patterns lacking cool upwelling with greater susceptibility to warming associated with climate change. Determining the rate of marine habitat changes in the Atlantic and Pacific Oceans is important to the conservation of these species, including subtleties of temporal and spatial habitat use, and adaptability to ocean ecosystems under climate change.

The initial societal paradigm was that nature is inefficient and hatcheries could be used to conserve stocks that were over utilized or suffering habitat degradation. Although these early hatcheries failed to meet their conservation objectives, they succeeded in developing the spawning-to-swimup fry culture technology used today. In the 1930s the paradigm shifted to artificial and natural production being equally effective and led to the closure of Federal hatcheries in areas with intact freshwater habitat. Hatcheries were maintained to mitigate for habitat loss from hydropower development. With the development of cost effective smolt production technology by 1960, the paradigm returned to nature being inefficient and ushered in the massive conservation utilization production of Pacific salmon that continues to this day. The early 1990s saw another paradigm shift with nature's inefficiency recognized as being the foundation for evolution to maintain the fitness of salmon in their natural environment. This shift gave rise to a focus for hatchery technology to preserve stocks in their native habitats. Using hatcheries for preservation-conservation has become the norm for Atlantic salmon in the USA and Atlantic Canada and for Pacific salmon stocks listed under the Endangered Species Act in the USA or as species at risk in Canada.

We compare the estuarine use between juvenile Atlantic salmon (Salmo salar) in the Penobscot River estuary and Pacific salmon (Oncorhynchus spp.) in the Columbia River estuary. Both estuaries have been degraded by anthropogenic activities. Atlantic and Pacific salmon populations in both basins rely heavily on hatchery inputs for persistence. Pacific salmon, as a group, represent a continuum of estuarine use, from species that move through rapidly to those that make extensive use of estuarine habitats. While Atlantic salmon estuarine use is predominantly similar to rapidly moving Pacific salmon, they can exhibit nearly the entire range of Pacific salmon estuarine use. Both slow and rapidly migrating Atlantic and Pacific salmon actively feed in estuarine environments, consuming insect and invertebrate prey. Interactions between juvenile salmon and estuarine fish communities are poorly understood in both estuaries, although they experience similar avian and marine mammal predators. Estuaries are clearly important for Atlantic and Pacific salmon, yet our understanding of this use is currently insufficient to make informed judgments about habitat quality or overall estuary health. This review of salmonid migration through and residency within estuaries identifies actions that could hasten restoration of both Atlantic and Pacific salmon populations.

AN - 1555247789; 24932500 AB - Pharmaceuticals and personal care products (PPCPs) such as caffeine and sulfamethoxazole have been detected in the estuarine environment. The present study characterized effects of a maternal exposure of these compounds on the development of the daggerblade grass shrimp Palaemonetes pugio from embryo to juvenile life stage. Ovigerous females were exposed to either caffeine (20 mg/L), sulfamethoxazole (60 mg/L), or a mixture of both (20 mg/L caffeine and 60 mg/L sulfamethoxazole). Embryos were then removed from the females and the effects of the PPCPs on hatching, metamorphosis, juvenile growth, and overall mortality were determined. No significant effect was observed on gravid female survival after 5 d of exposure to caffeine, sulfamethoxazole, or the mixture; however, development of the embryos on the female shrimp was delayed in the mixture. Caffeine and sulfamethoxazole in the mixture significantly reduced embryo survival. There was a significant effect of caffeine, sulfamethoxazole, and the mixture on embryo hatching time. Exposure to sulfamethoxazole alone significantly delayed larval metamorphosis. Exposure to caffeine and sulfamethoxazole separately led to significantly smaller length of juvenile shrimp. Maternal exposure to caffeine and sulfamethoxazole, individually and in mixture, resulted in negative effects on P. pugio offspring survival and development; however, the concentrations tested in the present study were well above maximum detected field concentrations. These results may be incorporated into PPCP risk assessments to protect sensitive estuarine ecosystems more effectively. © 2014 SETAC.

AN - 1551019160; 24854874 AB - In a worldwide collaborative effort, 19,630 Y-chromosomes were sampled from 129 different populations in 51 countries. These chromosomes were typed for 23 short-tandem repeat (STR) loci (DYS19, DYS389I, DYS389II, DYS390, DYS391, DYS392, DYS393, DYS385ab, DYS437, DYS438, DYS439, DYS448, DYS456, DYS458, DYS635, GATAH4, DYS481, DYS533, DYS549, DYS570, DYS576, and DYS643) and using the PowerPlex Y23 System (PPY23, Promega Corporation, Madison, WI). Locus-specific allelic spectra of these markers were determined and a consistently high level of allelic diversity was observed. A considerable number of null, duplicate and off-ladder alleles were revealed. Standard single-locus and haplotype-based parameters were calculated and compared between subsets of Y-STR markers established for forensic casework. The PPY23 marker set provides substantially stronger discriminatory power than other available kits but at the same time reveals the same general patterns of population structure as other marker sets. A strong correlation was observed between the number of Y-STRs included in a marker set and some of the forensic parameters under study. Interestingly a weak but consistent trend toward smaller genetic distances resulting from larger numbers of markers became apparent. Copyright © 2014 The Authors. Published by Elsevier Ireland Ltd..

AN - 1557083172; 25075449 AB - The directed self-assembly (DSA) of block copolymers (BCP) is an emerging resolution enhancement tool that can multiply or subdivide the pitch of a lithographically defined chemical or topological pattern and is a resolution enhancement candidate to augment conventional lithography for patterning sub-20 nm features. Continuing the development of this technology will require an improved understanding of the polymer physics involved as well as experimental confirmation of the simulations used to guide the design process. Both of these endeavors would be greatly facilitated by a metrology, which is capable of probing the internal morphology of a DSA film. We have developed a new measurement technique, resonant critical-dimension small-angle X-ray scattering (res-CDSAXS), to evaluate the 3D buried features inside the film. This is an X-ray scattering measurement where the sample angle is varied to probe the 3D structure of the film, while resonant soft X-rays are used to enhance the scattering contrast. By measuring the same sample with both res-CDSAXS and traditional CDSAXS (with hard X-rays), we are able to demonstrate the dramatic improvement in scattering obtained through the use of resonant soft X-rays. Analysis of the reciprocal space map constructed from the res-CDSAXS measurements allowed us to reconstruct the complex buried features in DSA BCP films. We studied a series of DSA BCP films with varying template widths, and the internal morphologies for these samples were compared to the results of single chain in mean-field simulations. The measurements revealed a range of morphologies that occur with changing template width, including results that suggest the presence of mixed morphologies composed of both whole and necking lamella. The development of res-CDSAXS will enable a better understanding of the fundamental physics behind the formation of buried features in DSA BCP films.

AN - 1669442113; 16232 AB - PURPOSE: An action that will make substantial changes to the final EIS for the setting of annual subsistence harvest of northern fur seals on the Pribilof Islands (July 2005) is proposed. The purpose of the proposed action is to conserve northern fur seals and manage the subsistence harvest of fur seals on St. George Island for their long-term sustainable use for purposes of cultural continuity, food, clothing, arts, and crafts. The Pribilof Islands and the surrounding Bering Sea marine environment support high concentrations of marine mammals, seabirds, fish, and invertebrates. All of these marine resources are used for subsistence purposes by residents of the Pribilof Islands. Subsistence resources are utilized as they are seasonally available, and often have complex spiritual and cultural underpinnings regarding when and how resources are collected and used. Pribilovians consume more fur seal meat than any other subsistence resource, and other species are not available at the same time to replace fur seals as a food source. This final supplemental EIS considers one no action alternative, and three action alternatives. Alternative 1 is the no action alternative and would maintain existing management of the northern fur seal harvest on St. George Island. Alternative 2, the Preferred Alternative, would modify the current harvest management regime to (1) create a second harvest season in the autumn for taking up to 150 young of the year male northern fur seals, such that the total allowable harvest range of 300-500 fur seals does not increase, (2) add a new conservation control to prevent more than three females from being killed during the harvest, (3) add a new conservation control to allow harvests only at those breeding areas capable of sustaining a harvest, and (4) encourage the development of best harvest practices within the co-management structure to minimize sub-lethal effects to seals not harvested. Alternative 3 would modify the northern fur seal subsistence harvest to (1) create a harvest season in the autumn for taking of up to 500 young of the year male northern fur seals, (2) reduce the subsistence harvest of sub-adult male northern fur seals to zero, (3) add a new conservation control to prevent more than 10 females from being killed during harvest, (4) add a new conservation control to allow harvests only at those breeding areas capable of sustaining a harvest, and (5) encourage the development of best harvest practices within the co-management structure to minimize sub-lethal effects to seals not harvested. Alternative 4 would modify the northern fur seal subsistence harvest to (1) create a second harvest season in the autumn for taking of up to 50 young of the year male northern fur seals, such that the total allowable harvest range of 300-500 fur seals does not increase, (2) add a new conservation control to prevent more than 20 females from being killed during harvest, (4) add a new conservation control to allow harvests only at those breeding areas capable of sustaining a harvest, and (4) encourage the development of best harvest practices within the co-management structure to minimize sub-lethal effects to seals not harvested. POSITIVE IMPACTS: While having minimal impact on the fur seal population, the preferred alternative would meet the documented subsistence needs of the Aleuts on St. George Island. NEGATIVE IMPACTS: The Preferred Alternative would: (1) affect mortality of up to 350 sub-adult male, 150 young of the year, and 3 female seals per year; and (2) 2,000 to 17,000 fur seals would be exposed to sub-lethal effects.

AN - 1669442108; 16227 AB - PURPOSE: An amendment to the September 2011 generic Fishery Management Plan for the Shrimp Fishery of the Gulf of Mexico, United States Waters is proposed. Under the generic plan, for royal red shrimp, the no action alternatives and discussions were incorrect in stating that there were currently no management restrictions although a quota and in-season quota closure were in the regulations. Now, the quota and in-season closure are in conflict with and redundant to the subsequently established ACL and AM. The purpose of this amendment is select an annual catch limit (ACL) and accountability measures (AM) for royal red shrimp. This draft EIS analyzes a range of alternatives for two actions. Action 1 is to adjust the annual catch limit and quota for royal red shrimp. The current ACL is 334,000 lbs and the current quota is 392,000 lbs. The ACL was set in the 2012 regulations to equal the acceptable biological catch (ABC). In March 2014, the Councils Scientific and Statistical Committee revised the ABC from 334,000 lbs to 337,000 lbs. Action 1 addresses the ACL and quota conflict with three alternatives. Alternative 1 is the no action alternative and would be inconsistent with the Magnuson-Stevens Fishery Conservation and Management Act because the quota can be equal to, but cannot be higher than, the ABC. Alternative 2 would remove the quota and retain the ACL, resolving the conflict. Preferred Alternative 3 would also remove the quota and retain the ACL, but also increase the ACL to 337,000 lbs. Action 2 would adjust the accountability measure and closure procedures for royal red shrimp. The original management plan for shrimp established in-season monitoring and an in-season closure if the quota is met or projected to be met. The 2012 regulations set a post-season accountability measure under which NMFS will not monitor landings in-season unless the ACL is exceeded in one year, based on a review of landings after the end of the year. Then, NMFS will monitor the stock in-season in the following year and implement a closure if landings reach or are projected to reach the ACL in the second year. If a closure is not necessary the second year, then in-season monitoring will stop in subsequent years unless the ACL is exceeded again. Action 2 addresses the AM redundancy with three alternatives. Alternative 1, no action, would retain both AMs; however, the in-season closure makes the second season monitoring and closure from the 2012 rule irrelevant because NMFS would monitor landings in-season every year. Preferred Alternative 2 retains the 2012 AM that triggers in-season monitoring and closures only if the ACL was exceeded in the previous year, and removes the in-season quota closure that could occur every year. The Council chose this AM previously because they determined they had no reason to expect that the stock would exceed its ACL and wished to reduce the administrative burden of quota monitoring. Alternative 3 would retain the in-season monitoring and closure and remove the 2012 AM. POSITIVE IMPACTS: The specification of overfishing limits, ACLs, and AMs, where needed would comply with the reauthorized Magnuson-Stevens Act requirements. Implementation is expected to prevent overfishing and achieve optimum yield while minimizing to the extent practicable adverse social and economic effects. NEGATIVE IMPACTS: The preferred alternatives could allow an overage in a year before the AM would be triggered, which would have increased negative impacts on the physical and biological environments. Those impacts would include additional fishing mortality and impacts to habitat from fishing gear. Lowering the quota and triggering AMs may result in negative short-term effects on the social and economic environments, if those limits constrain catch below recent levels. However, these effects are unlikely because recent landings are well below any quota or catch level proposed.

Preparation date: August 22, 2014 N1 - Last updated - 2015-04-03 ER - TY - RPRT T1 - GULF OF ALASKA NAVY TRAINING ACTIVITIES, ALASKA (DRAFT SUPPLEMENT TO THE FINAL ENVIRONMENTAL IMPACT STATEMENT OF MARCH 2011). AN - 1669442107; 16229 AB - PURPOSE: Current, emerging, and future US Navy training activities in the Gulf of Alaska are proposed. This draft supplement to the final EIS of March 2014 does not substantially change the proposed action alternative of March 2011, but supplements the environmental information and analysis contained in the final EIS. Subsequently, the alternatives analyzed in this draft supplemental EIS are the same as analyzed in the 2011 final EIS. The No Action Alternative is continue baseline training activities of the types and levels of training intensity prior to 2011, which did not include Anti-submarine Warfare (ASW) training activities involving the use of sonar. Alternative 1 includes adjustments to the types and levels of activities from the baseline, as necessary, to support current and planned Navy training requirements, including: (1) all training activities addressed in the No Action Alternative and an increase in training activities; (2) conducting one large-scale carrier strike group (CSG) exercise, plus ASW training activities and the use of active sonar, occurring over a maximum time period of up to 21 consecutive days during the April-October timeframe; (3) training required by force structure changes for new weapons systems, instrumentation, and technology as well as new classes of chips, submarines, and types of aircraft; and (4) development and use of the portable undersea tracking range. Alternative 2 includes all elements of Alternative 1 plus one additional CSG exercise during the summer months (April-October). Additionally, Alternative 2 includes conducting one sinking exercise per CSG exercise for a total of two per year. POSITIVE IMPACTS: Establishing and executing training programs, including at-sea exercises, and ensuring naval forces have access to the ranges, operating areas, and airspace needed to develop and maintain skills for conducting naval activities would demonstrate and evaluate the ability of the services to carry out plans in response to a national security threat. Alternative 2 would allow the greatest flexibility for Navy exercise planners to benefit from the unique joint training environment in the ATA. NEGATIVE IMPACTS: Marine mammal species occurring in the Study Area may be impacted by multiple ongoing and future actions. Explosive detonations and non-impulse sources such as sonar under the No Action Alternative, Alternative 1, and Alternative 2 have the potential to disturb, injure, or kill marine mammals; however, there are very few injuries and no mortalities expected or predicted by the acoustic effect modeling.

SINKEX training would result in 70,000 pounds per year of expended material with one percent considered hazardous.

AN - 1542007255; 24880550 AB - Long-term fire retardants are used to prevent the spread of wildland fire, but have inadvertently entered aquatic habitats and resulted in fish kills. We examined the toxicity of two fire retardant products; PHOS-CHEK 259F and LC-95A, on Chinook salmon with two different life histories, ocean-type and stream-type, at different stages of their development. Ocean-type Chinook outmigrate to the ocean as subyearlings; while, stream-type salmon overwinter in freshwater and outmigrate as yearlings. Ocean-type and stream-type salmon were exposed to the fire retardants prior to their parr to smolt transition (presmolts) as subyearlings (stream-type and ocean-type) and yearlings (stream-type only), as well as during their transition (smolts). The salmon were exposed to eight concentrations of each retardant and a control for 96h to determine acute toxicity. Lethal concentration curves were modeled by logistic regression for each life history and life stage exposed to the two fire retardants. Among all life histories and life stages tested, PHOS-CHEK 259F was most toxic to stream-type salmon at smolt stage and PHOS-CHEK LC-95A was most toxic to ocean-type salmon at smolt stage. To determine the delayed effects of product exposures on fish health as well as for the potential of recovery, 24-hour seawater challenges were performed immediately after fire retardant exposure, as well as after a recovery period. Previous PHOS-CHEK exposure reduced survival during seawater challenge among salmon from both life histories undergoing the parr-smolt transition and was more pronounced after PHOS-CHEK LC-95A exposure. However, this delayed effect was not observed 34 or more days after either PHOS-CHEK exposure. We conclude that accidental PHOS-CHEK LC-95A or 259F drops during salmon outmigration would have adverse impacts that extend beyond the acute mortality that occurs within the immediate drop and dilution areas.

This study reports a rapid assay for the detection of pathogenic Leptospira spp. in California sea lions Zalophus californianus using real-time PCR with primers and a probe targeting the lipL 32 gene. The PCR assay had high analytic sensitivity-the limit of detection was 3 genome copies per PCR volume using L. interrogans serovar Pomona DNA and 100% analytic specificity; it detected all pathogenic leptospiral serovars tested and none of the non-pathogenic Leptospira species (L. biflexa and L. meyeri serovar Semaranga), the intermediate species L. inadai, or the non-Leptospira pathogens tested. Our assay had an amplification efficiency of 1.00. Comparisons between the real-time PCR assay and culture isolation for detection of pathogenic Leptospira spp. in urine and kidney tissue samples from California sea lions showed that samples were more often positive by real-time PCR than by culture methods. Inclusion of an internal amplification control in the real-time PCR assay showed no inhibitory effects in PCR negative samples. These studies indicated that our real-time PCR assay has high analytic sensitivity and specificity for the rapid detection of pathogenic Leptospira species in urine and kidney tissue samples.

HIMU-DMM mixing and melting controlled by a progressively thinning lithospheric lid AN - 1777469774; 2016-027390 AB - The Cobb Seamount Chain in the northeast Pacific basin records the composition of the Cobb hot spot for the past 33 Myr, as the migrating Juan de Fuca Ridge approached and ultimately overran it ca. 0.5 Myr ago. In this first comprehensive geochemical study of the Cobb chain, major and trace element compositions and Sr, Nd, Pb, and Hf isotopic ratios were measured for whole-rock samples from throughout the chain, and He isotopes were acquired for olivine phenocrysts from one seamount. Trace element modeling indicates increased melting along the chain over time, with progressively more depleted lavas as the ridge approached the hot spot. The isotopic data reveal the first evidence of the high mu (mu = (super 238) U/ (super 204) Pb) (HIMU) mantle component in the north Pacific basin and are consistent with a progressively decreasing mixing proportion of HIMU melts relative to those from depleted mid-ocean ridge basalt mantle (DMM) in the chain over time. Decreasing lithospheric thickness over the Cobb hot spot due to the approach of the migrating Juan de Fuca ridge allowed adiabatic melting to continue to shallower depths, leading to increased melt fractions of the refractory DMM component in the hot spot and more depleted and MORB-like lavas in the younger Cobb seamounts.

Deciphering the role of a specific process is often frustrated by simultaneous changes in other influences. Here we take advantage of the almost constant spreading rate (65-71 mm/yr) along 2500 km of the Southeast Indian Ridge (SEIR) between 77 degrees E and 99 degrees E to examine the spatial density of hydrothermal venting relative to regional and segment-scale changes in the apparent magmatic budget. We use 227 vertical profiles of light backscatter and (on 41 profiles) oxidation-reduction potential along 27 first and second-order ridge segments on and adjacent to the Amsterdam-St. Paul (ASP) Plateau to map p (sub h) , the fraction of casts detecting a plume. At the regional scale, venting on the five segments crossing the magma-thickened hot spot plateau is almost entirely suppressed (p (sub h) = 0.02). Conversely, the combined p (sub h) (0.34) from all other segments follows the global trend of p (sub h) versus spreading rate. Off the ASP Plateau, multisegment trends in p (sub h) track trends in the regional axial depth, high where regional depth increases and low where it decreases. At the individual segment scale, a robust correlation between p (sub h) and cross-axis inflation for first-order segments shows that different magmatic budgets among first-order segments are expressed as different levels of hydrothermal spatial density. This correlation is absent among second-order segments. Eighty-five percent of the plumes occur in eight clusters totaling approximately 350 km. We hypothesize that these clusters are a minimum estimate of the length of axial melt lenses underlying this section of the SEIR. Abstract Copyright (2014), American Geophysical Union.

In addition, the projected future climate fluctuation results will be used to assist the maximum performance of wheat and to be used as the main basis for planning changes in the farming calendar in Iran. Observed climate (temperature and degree day) changes during the period (1951-2009) will be discussed. Projected future changes up to 2100 based on the MAGICC/SCENGEN 5.3 compound model was utilized. Furthermore, 18 scenarios were used to derive a single GCM model referred to as the United Kingdom Hadley Center Global Environment Model, which will be used to select the worst, best, and average scenario.

According to observations and climate models, at least part of this decline is associated with changes in large-scale atmospheric circulation, including a poleward movement of the westerly winds and increasing atmospheric surface pressure over parts of southern Australia. Here we use a high-resolution global climate model to analyse the causes of this rainfall decline. In our simulations, many aspects of the observed regional rainfall decline over southern and southwest Australia are reproduced in response to anthropogenic changes in levels of greenhouse gases and ozone in the atmosphere, whereas anthropogenic aerosols do not contribute to the simulated precipitation decline. Simulations of future climate with this model suggest amplified winter drying over most parts of southern Australia in the coming decades in response to a high-end scenario of changes in radiative forcing. The drying is most pronounced over southwest Australia, with total reductions in austral autumn and winter precipitation of approximately 40% by the late twenty-first century.

AN - 16380975; 16204 AB - PURPOSE: A boundary expansion of the Thunder Bay National Marine Sanctuary (TBNMS) in northwestern Lake Huron, Michigan is proposed. Thunder Bay is adjacent to one of the most treacherous stretches of water within the Great Lakes system and the 448-square-mile TBNMS protects one of America's best-preserved collections of shipwrecks. Well preserved by Lake Hurons cold, fresh water, the shipwrecks and related maritime heritage sites in and around Thunder Bay are historically, archaeologically and recreationally significant. During the sanctuary's management plan review in 2006, the National Oceanic and Atmospheric Administration (NOAA) received comments encouraging the expansion of the sanctuary's boundary to include the waters adjacent to Alcona and Presque Isle counties. Three alternatives are considered in this final EIS. The No Action Alternative (Alternative A) represents the existing boundary which extends lakeward to longitude 83 degrees west and is delineated to the north and south by the respective Alpena County lines. This 448-square-mile area contains 45 shipwrecks and 40 suspected shipwrecks. The 808-square-mile boundary alternative (Alternative B) is defined by the Presque Isle Lighthouse in Presque Isle County, south to Sturgeon Point Lighthouse in Alcona County, east to longitude 83 degrees west. This area was NOAAs preferred boundary during the sanctuarys initial designation in the year 2000 and contains 60 known shipwrecks and approximately 64 undiscovered shipwrecks. Under the preferred alternative (Alternative C), TBNMS would encompass 4,300 square miles and the sanctuary boundary would extend westward to the international border with Canada. This alternative would add 47 known historic shipwrecks. Among them are some of the Great Lakes best preserved and recreationally significant shipwrecks. Archival research indicates that as many as 60 additional historic shipwrecks could be discovered in this proposed expanded area. The new boundary would include all 92 historic shipwrecks in Alpena, Alcona and Presque Isle Counties, and five shipwrecks from Mackinaw and Cheboygan Counties. POSITIVE IMPACTS: The proposed expansion would provide protection for unique historic sites within the maritime landscape but beyond the current boundaries of the TBNMS. The sanctuarys research and monitoring, education, and resource protection programs (including law enforcement) would preserve important national treasures while allowing recreational use of the resources. NEGATIVE IMPACTS: The boundary expansion for TBNMS is not expected to have any adverse effects.

That flow involves a net mass transfer into the Red Sea during fall and out during spring, though in summer there is an influx of cool water at intermediate depths. Thus, summer water in the south is warmer near the surface due to higher air temperatures, but cooler at intermediate depths. Summer water in the north experiences warming by air-sea exchange only. The temperature affects water density, which impacts SSH but has no effect on mass. We study this seasonal cycle by combining GRACE mass estimates, altimeter SSH measurements, and steric contributions derived from the World Ocean Atlas temperature climatology. Among our conclusions are: mass contributions are much larger than steric contributions; the mass is largest in winter, consistent with winds pushing water into the Red Sea in fall and out during spring; the steric signal is largest in summer, consistent with surface warming; and the cool, intermediate-depth water flowing into the Red Sea in spring has little impact on the steric signal, because contributions from the lowered temperature are offset by effects of decreased salinity. The results suggest that the combined use of altimeter and GRACE measurements can provide a useful alternative to in situ data for monitoring the steric signal. Abstract Copyright (2014), .

The results of simulating two selected typhoon cases indicate that the nonbreaking wave-stirring-induced mixing has significant impacts on UOTS and the typhoon intensity, and the incorporation of the simple WMP scheme in the coupled model helps to improve the simulation of UOTS and thus the typhoon intensity. In the case that the typhoon intensity is underestimated by the atmosphere model alone, the improvement of initial UOTS by the ocean model with the WMP included can deepen the initial thermocline depth, reduce the effect of SST cooling, and prevent the typhoon intensity from undesired weakening. In the case that the typhoon intensity is overestimated (with strong winds), including the WMP in the ocean model significantly enhances the total vertical mixing rate in the upper ocean, which in turn enhances the SST cooling and thus reduces the typhoon intensity as desired. The results obtained in this study make a contribution to the ongoing efforts of improving the typhoon intensity forecast using a regional atmosphere-ocean coupled model by worldwide researchers and forecasters, especially for the typhoons in the SCS regions.

We characterize the seasonal, diurnal, and geographic variability of DDL activity in retrievals from observations by the Mars Climate Sounder onboard Mars Reconnaissance Orbiter. We find that dust injection above the boundary layer, which forms DDLs, is a spatially ubiquitous phenomenon in the tropics during the daytime, implying that it has a significant nontopographic component. DDL formation is more intense in northern spring and summer than in southern spring and summer but is still common when the zonal average dust distribution appears uniformly mixed. DDLs do not appear to follow the upwelling associated with Mars's Hadley circulation or the extant climatology of local dust storm activity in the tropics. Geographic variability in the nightside vertical dust distribution does not always correlate with the dayside vertical dust distribution, implying that there is spatial and seasonal variability in the efficiency of dust deposition/removal processes. Nighttime dust removal is especially efficient over the Tharsis Montes during northern spring and summer, which suggests some association between water ice clouds and removal. Intense injection combined with efficient removal results in a high amplitude of diurnal variability in the dust distribution at 15-30 km above the surface of the tropics during much of the Martian year.

The NIPA estimates for the first quarter of 2014 and for earlier years have been revised. This upturn in the second-quarter percent change in real GDP primarily reflected upturns in inventory investment and in exports, an acceleration in consumer spending, an upturn in state and local government spending, an acceleration in nonresidential fixed investment, and an upturn in residential fixed investment that were partly offset by an acceleration in imports. Real disposable personal income (DPI) increased 3.8% in the second quarter after increasing 3.5 percent in the first quarter. Current-dollar DPI increased 6.2% in the second quarter after increasing 4.9% in the first quarter. The sharper acceleration in current-dollar DPI than in real DPI reflected an acceleration in the implicit price deflator for consumer spending, which is used to deflate DPI.

Unionization over the Life-Cycle of U.S. Businesses AN - 1629325034; 2011-760292 AB - What type of businesses do unions target for organizing? A dynamic model of the union organizing process is constructed to answer this question. A union monitors establishments in an industry to learn about their productivity and decides which ones to organize and when. An establishment becomes unionized if the union targets it for organizing and wins the union certification election. The model predicts two main selection effects: unions secure elections in larger and more productive establishments early in their life-cycles, and among the establishments that experience an election, unions are more likely to win in smaller and less productive ones. These predictions find support in union certification election data for 1977-2007 matched with data on establishment characteristics. Other empirical regularities pertaining to union organizing are also documented. Tables, Figures, Appendixes, References.

As is usual for annual NIPA revisions, the revised estimates incorporated newly available source data that are more complete, more detailed, and more reliable than those that were previously incorporated. In addition to the revisions for the more recent years, this year's annual revision included revisions to gross domestic product (GDP) and some of its components beginning with the estimates for 1999. This annual revision has not greatly changed the overall picture of GDP growth over the revision period, consistent with BEA research that shows that annual NIPA revisions do not greatly change the overall economic picture. With the revised estimates of real GDP, the general picture of economic growth, including the pattern of the current economic recovery, remains largely the same. The most notable revisions are for the period 2011-2013 and largely reflect the incorporation of newly available and revised source data. Adapted from the source document.

We quantify the seasonality of satellite-derived, oceanic net primary production (NPP) and its interannual variability during the first decade of the SeaWiFS mission (1998 to 2007) using a normalized seasonality index (NSI). The NSI, which is based upon production half-time, t(1/2), generally becomes progressively more episodic with increasing latitude in open ocean waters, spanning from a relatively constant rate of primary productivity throughout the year (mean t(1/2) similar to 5 months) in subtropical waters to more pulsed events (mean t(1/2) similar to 3 months) in subpolar waters. This relatively gradual, poleward pattern in NSI differs from recent estimates of phytoplankton bloom duration, another measure of seasonality, at lower latitudes ( similar to 40 degree S-40 degree N). These differences likely reflect the temporal component of production assessed by each metric, with NSI able to more fully capture the irregular nature of production characteristic of waters in this zonal band. The interannual variability in NSI was generally low, with higher variability observed primarily in frontal and seasonal upwelling zones. The influence of the El Nino-Southern Oscillation on this variability was clearly evident, particularly in the equatorial Pacific, where primary productivity was anomalously episodic from the date line east to the coast of South America in 1998. Yearly seasonality and the magnitude of annual production were generally positively correlated at mid-latitudes and negatively correlated at tropical latitudes, particularly in a region bordering the Pacific equatorial divergence. This implies that increases of annual production in the former region are attained over the course of a year by shorter duration but higher magnitude NPP events, while in the latter areas it results from an increased frequency or duration of similar magnitude events. Statistically significant trends in the seasonality, both positive and negative, were detected in various patches. We suggest that NSI be used together with other phenomenological characteristics of phytoplankton biomass and productivity, such as the timing of bloom initiation and duration, as a means to remotely quantify phytoplankton seasonality and monitor the response of the oceanic ecosystem to environmental variability and climate change.

MLM utilizes a resistance analogy to calculate deposition velocities appropriate for whole vegetative canopies, while employing a multilayer integration to account for vertically varying meteorology, canopy morphology and radiative transfer within the canopy. However, the MLM formulation, as it was originally presented and as it has been subsequently employed, contains a non-physical representation related to the leaf-level quasi-laminar boundary layer resistance that affects the calculation of the total canopy resistance. In this note, the non-physical representation of the canopy resistance as originally formulated in MLM is discussed and a revised, physically consistent, formulation is suggested as a replacement. The revised canopy resistance formulation reduces estimates of HNO3 deposition velocities by as much as 38% during mid-day as compared to values generated by the original formulation. Inferred deposition velocities for SO2 and O3 are not significantly altered by the change in formulation (<3%). Inferred deposition loadings of oxidized and total nitrogen from CASTNet data may be reduced by 10-20% and 5-10%, respectively, for the Eastern U. S. when employing the revised formulation of MLM as compared to the original formulation.

The vertical integral of the 14 year delta (super 13) C change was assessed in five latitude bands and found to be greatest (-14.7 ppm m yr (super -1) ) in the subpolar band (38 degrees S-55 degrees S) and smallest (-3.0 ppm m yr (super -1) ) in the tropical band (21 degrees N-18 degrees S). The delta (super 13) C change in each of the latitudinal bands was primarily caused by inputs of anthropogenic CO (sub 2) via air-sea exchange and transport. More than 50% of the total anthropogenic CO (sub 2) was added to the subpolar band via the northward movement of Antarctic Intermediate Water (AAIW) from the south, and the remaining 50% was added via air-sea exchange. We also calculated the ratio of the temporal change in delta (super 13) C to the change in dissolved inorganic carbon, which is a measure of the efficiency of oceanic uptake of anthropogenic CO (sub 2) . The ratio for AAIW in 1994 (-0.017 ppm (mu mol kg (super -1) ) (super -1) ) was greater than that in 2008 (-0.010 ppm (mu mol kg (super -1) ) (super -1) ) based on the change in preformed delta (super 13) C and dissolved inorganic carbon (DIC), indicating reduced efficiency of CO (sub 2) uptake by the Southern Ocean in 2008 relative to that in 1994. AAIW remained at the surface for a shorter period in 2008 relative to 1994, and thus would have taken up less atmospheric CO (sub 2) prior to subduction. The projected reduction in this ratio indicates a weakening of CO (sub 2) uptake by the Southern Ocean in the future. Abstract Copyright (2014), . American Geophysical Union. All Rights Reserved.

Environmental stressors acting individually or concurrently and synergistically are reducing the ability of coastal ecosystems to provide key ecosystem services that may result in decreases in human health and well-being. We outline some impacts to human health and well-being that may result from the effects on coastal and ocean ecosystem services of five example stressors: rising temperatures, nutrient enrichment, ocean acidification, habitat destruction and the concomitant loss of biodiversity, and extreme weather events. We conclude with suggestions for research and related actions to improve our understanding and management of coastal ecosystems. These include the need for natural and biomedical/public health scientists, and their respective professional organizations, to work together to increase understanding of the connections between healthy and degraded coastal and marine ecosystems and human health, and for policy and decision-makers to account for these impacts when considering trade-offs among management alternatives.

EBAs are informed by integrated ecosystem assessments (IEAs) that must be compiled and updated frequently for EBAs to be effective. Frequently updated IEAs depend on the sustained provision of data and information on pressures, state changes, and impacts of state changes on services. Nowhere is this truer than in the coastal zone, where people and ecosystem services are concentrated and where anthropogenic pressures converge. This study identifies the essential indicator variables required for the sustained provision of frequently updated IEAs, and offers an approach to establishing a global network of coastal observations within the framework of the Global Ocean Observing System. The need for and challenges of capacity-building are highlighted, and examples are given of current programmes that could contribute to the implementation of a coastal ocean observing system of systems on a global scale. This illustrates the need for new approaches to ocean governance that can achieve coordinated integration of existing programmes and technologies as a first step towards this goal.

It is noted that both the precipitation and T2m variations in Northeast China are dominated by interannual and higher frequency variations. However, on interdecadal time scales, T2m is shifted significantly from below normal to above normal around 1987/1988. Statistically, the seasonal mean precipitation and T2m are largely driven by local internal atmospheric variability rather than remote forcing. For the precipitation variation, circulation anomalies in the low latitudes play a more important role in spring and summer than in autumn and winter. For T2m variations, the associated sea surface pressure (SLP) and 850-hPa wind (uv850) anomalies are similar for all seasons in high latitudes with significantly negative correlations for SLP and westerly wind anomaly for uv850, suggesting that a strong zonal circulation in the high latitudes favors warming in Northeast China. The predictability of precipitation and T2m in Northeast China is assessed by using the Atmospheric Model Inter-comparison Project type experiments which are forced by observed sea surface temperature (SST) and time-evolving greenhouse gas (GHG) concentrations. Results suggest that T2m has slightly higher predictability than precipitation in Northeast China. To some extent, the model simulates the interdecadal shift of T2m around 1987/1988, implying a possible connection between SST (and/or GHG forcing) and surface air temperature variation in Northeast China on interdecadal time scales. Nevertheless, the precipitation and T2m variations are mainly determined by the unpredictable components which are caused by the atmospheric internal dynamic processes, suggesting low predictability for the climate variation in Northeast China.

Satellite retrievals of water vapor have been developed, but they are limited by the use of a models first guess, instrument spectral resolution, horizontal footprint size, and vertical resolution. In 2016, Geostationary Operational Environmental Satellite-R (GOES-R), the first in a series of new-generation geostationary satellites, will be launched. Its Advanced Baseline Imager will provide unprecedented spectral, spatial, and temporal resolution. Among the bands are two centered at 10.35 and 12.3 m. The brightness temperature difference between these bands is referred to as the split-window difference, and has been shown to provide information about atmospheric column water vapor. In this paper, the split-window difference is reexamined from the perspective of GOES-R and radiative transfer model simulations are used to better understand the factors controlling its value. It is shown that the simple split-window difference can provide useful information for forecasters about deepening low-level water vapor in a cloud-free environment.

(432 mm) of rainfall fell over parts of Boulder County, Colorado, with more than 8 in. (203 mm) over a wide swath of Colorados northern Front Range. This caused significant flash and river flooding, loss of life, and extensive property damage. The event set a record for daily rainfall (9.08 in., or >230 mm) in Boulder that was nearly double the previous daily rainfall record of 4.8 in. (122 mm) set on 31 July 1919. The operational performance of precipitation forecast guidance from global ensemble prediction systems and the National Weather Services global and regional forecast systems during this event is documented briefly in the article and more extensively in online supplemental appendixes. While the precipitation forecast guidance uniformly depicted a much wetter-than-average period over northeastern Colorado, none of the global nor most of the regional modeling systems predicted precipitation amounts as heavy as analyzed. Notable exceptions to this were the Short-Range Ensemble Forecast (SREF) members that used the Advanced Research Weather Research and Forecasting Model (ARW-WRF) dynamical core. These members consistently produced record rainfall in the Front Range. However, the SREFs record rainfall was also predicted to occur the day before the heaviest actual precipitation as well as the day of the heaviest precipitation.

Logistic regression has the advantage over REEP in that the probability estimates are constrained between zero and unity, whereas REEP can overshoot these values. It may be a detriment in some applications that the curves developed, one for each of several predictand categories (events), are symmetric. This paper shows how the logit curve can easily be made nonsymmetric as a function of a predictor, and thereby possibly achieve a better fit to the data. As with REEP, the probabilities estimated by logistic regression for each of several categories of a variable may not be consistent. For instance, the probability of snow > 2 in. may exceed the probability of snow > 1 in. Such inconsistencies can be avoided by developing a single equation involving all predictand categories and including another predictor that is a function of the predictand. This effectively, for a single predictor, produces parallel curves separated along the predictor axis but imposes restrictions on the equations and probabilities produced from them. The relationship between the predictor(s) and the predictand must be considered in determining the functional form. With only one predictor, defining the function is relatively straightforward. However, with multiple predictors, the process is more problematic. This paper demonstrates an alternative to imposing a functional form by using binary predictors. This formulation also achieves the goal of producing consistent forecasts and generalizes more readily to multiple predictors.

When ice is absent, from July to October, energy is efficiently transferred from the atmosphere to the ocean, generating near-inertial internal waves. When ice is present, from November to June, storms also cause near-inertial oscillations in the ice and mixed layer, but kinetic energy is weaker and oscillations are quickly damped. Damping is dependent on ice pack strength and morphology. Decay scales are longer in early winter (November-January) when the new ice pack is weaker and more mobile, decreasing in late winter (February-June) when the ice pack is stronger and more rigid. Efficiency is also reduced, as comparisons of atmospheric energy available for internal wave generation to mixed layer kinetic energies indicate that a smaller percentage of atmospheric energy is transferred to near-inertial motions when ice concentrations are >90%. However, large kinetic energies and shears are observed during an event on 16 December and spectral energy is elevated above GarrettMunk levels, coinciding with the largest energy flux predicted during the deployment. A significant amount of near-inertial energy is episodically transferred to the internal wave band from the atmosphere even when the ocean is ice covered; however, damping by ice and less efficient energy transfer still leads to low Arctic internal wave energy in the near-inertial band. Increased kinetic energy below 300 m when ice is forming suggests some events may generate internal waves that radiate into the Arctic Ocean interior.

Additionally, in dual-polarized radars, samples of precipitation echo obtained in the two orthogonally polarized channels are substantially more correlated than samples of noise. Therefore, estimates of auto- and cross correlations can be used individually, collectively, and/or with power measurements to enhance detection of precipitation signals, compared to the approach that uses only power estimates from one channel. A possible advantage of using only estimates of coherency for signal detection is that the detectors performance is less sensitive to errors in noise power measurements. Hence, censoring is more likely to produce desired false alarm rates even if nonnegligible uncertainties are present in the noise power estimates. In this work these aspects are considered using real data from weather radars. Three novel censoring approaches are evaluated and compared to the censoring approach that uses only estimates of signal and noise powers. The first approach uses only cross-correlation measurements, and the second approach combines these with the lag-1 autocorrelation estimates. The third approach utilizes all estimates as in the previous two approaches in combination with power measurements from the horizontal and the vertical channels. Herein, it is shown that, when more accurate measurements of noise powers are available, the third approach produces the highest detection rates followed by the second and the first approaches. Also, it is corroborated that the first and the second approaches exhibit less sensitivity to inaccurate system noise power measurements than the third one.

The grand ensemble mean NMME_VIC forecasts were compared to ensemble streamflow prediction (ESP) forecasts derived from the VIC model forced by resampling of historical observations during the forecast period (ESP_VIC), using the same initial conditions as NMME_VIC. The forecast period is from 1982 to 2010, with the forecast initialized on 1 January, 1 April, 5 July, and 3 October. Overall, forecast skill is seasonally and regionally dependent. The authors found that 1) the skill of the grand ensemble mean NMME_VIC forecasts is comparable with that of the individual model that has the highest skill; 2) for all forecast initiation dates, the initial conditions play a dominant role in forecast skill at 1-month lead, and at longer lead times, forcings derived from NMME forecasts start to contribute to forecast skill; and 3) the initial conditions dominate contributions to skill for a dry climate regime that covers the western interior states for all seasons and the north-central part of the country for January. In this regime, the forecast skill for both methods is high even at 3-month lead. This regime has low mean precipitation and precipitation variations, and the influence of precipitation on SM and RO is weak. In contrast, a wet regime covers the region from the Gulf states to the Tennessee and Ohio Valleys for forecasts initialized in January and April, the Southwest monsoon region, the Southeast, and the East Coast in summer. In these dynamically active regions, where rainfall depends on the path of the moisture transport and atmospheric forcing, forecast skill is low. For this regime, the climate forecasts contribute to skill. Skillful precipitation forecasts after lead 1 have the potential to improve SM and RO forecast skill, but it was found that this mostly was not the case for the NMME models.

The study highlights key orographic influences on precipitation distributions and intensities across northern California during a landfalling atmospheric river (AR) and an associated Sierra barrier jet (SBJ). A detailed wind profiler/GPS analysis documents an intense AR overriding a shallow SBJ at similar to 750 m MSL, resulting in record early season precipitation. The SBJ diverts shallow, pre-cold-frontal, incoming water vapor within the AR poleward from the San Francisco Bay gap to the northern CV. The SBJ ultimately decays following the passage of the AR and trailing polar cold front aloft. A statistical analysis of orographic forcing reveals that both the AR and SBJ are crucial factors in determining the amount and spatial distribution of precipitation in the northern Sierra Nevada and in the Shasta-Trinity region at the northern terminus of the CV. As the AR and SBJ flow ascends the steep and tall terrain of the northern Sierra and Shasta-Trinity region, respectively, the precipitation becomes enhanced. Vertical profiles of the linear correlation coefficient quantify the orographic linkage between hourly upslope water vapor flux profiles and hourly rain rate. The altitude of maximum correlation (i.e., orographic controlling layer) is lower for the shallow SBJ than for the deeper AR (i.e., 0.90 versus 1.15 km MSL, respectively). This case study expands the understanding of orographic precipitation enhancement from coastal California to its interior.

The most hazardous conditions emerge when extreme daytime temperatures combine with warm night-time temperatures, high humidities and light winds for several consecutive days. Here, we assess present and future heat wave impacts on human health in Europe. Present daily physiologically equivalent temperatures (PET) are derived from the ERA-Interim reanalysis. PET allows to specifically focus on heat-related risks on humans. Regarding projections, a suite of high-resolution regional climate models - run under SRES A1B scenario - has been used. A quantile-quantile adjustment is applied to the daily simulated PET to correct biases in individual model climatologies and a multimodel ensemble strategy is adopted to encompass model errors. Two types of heat waves differently impacting human health - strong and extreme stress - are defined according to specified thresholds of thermal stress and duration. Heat wave number, frequency, duration and amplitude are derived for each type. Results reveal relatively strong correlations between the spatial distribution of strong and extreme heat wave amplitudes and mortality excess for the 2003 European summer. Projections suggest a steady increase and a northward extent of heat wave attributes in Europe. Strong stress heat wave frequencies could increase more than 40 days, lasting over 20 days more by 2075-2094. Amplitudes might augment up to 7 degrees C per heat wave day. Important increases in extreme stress heat wave attributes are also expected: up to 40 days in frequency, 30 days in duration and 4 degrees C in amplitude. We believe that with this information at hand policy makers and stakeholders on vulnerable populations to heat stress can respond more effectively to the future challenges imposed by climate warming.

There are few reliable estimates of post-release mortality for sea turtle species because of the many challenges and costs associated with tracking animals released at sea. In this study, the likelihood of sea turtle mortality as a result of interactions with longline fishing gear was estimated based on satellite telemetry data, such as the number of days an animal was successfully tracked, or days at liberty (DAL) and dive depth data, as well as anatomical hooking locations. 2. Pop-up satellite archival tags were deployed on 29 loggerhead sea turtles (Caretta caretta) caught by the North Pacific US-based pelagic longline fishery operating from California and Hawaii between 2002 and 2006. Loggerhead turtles were catagorized by observers as shallow-hooked (55%) if the animal was entangled in the line or the hook was in the flipper, jaw or mouth and could be removed, or deep-hooked (45%) if the hook was ingested and could not be removed. The vertical movements of turtles were used to infer potential mortalities. 3. Of the 25 tags that reported data, the DAL ranged from 3 to 243 days (mean=68 days). The DAL was shorter (by nearly 50%) for shallow-hooked (mean=48 days, range: 3 to 127) compared to deep-hooked turtles (mean=94 days, range: 5 to 243), but these changes were not statistically significant (P=0.0658). 4. Although aspects of these analyses may be considered speculative, these data provide empirical evidence to indicate that deep-hooking is not linked to shorter DAL. 5. DAL, anatomical hooking location, and gear removal were evaluated with inferences about the extent of injuries and rates of infection to estimate an overall post-release mortality rate of 28% (95% bootstrap CI: 16-52%). 6. This range of estimates is consistent with those used to shape some US fisheries management plans, suggesting that conservation goals are being achieved at the expected level and ideally striking a balance between the interests of industry and those of protected species.

In pelagic longline fisheries, albacore (Thunnus alalunga) are often caught in relatively cooler, deeper water (>100 m) than many species of conservation concern (e.g., sea turtles, billfishes, and some sharks) that are caught in shallower water (100 m) que muchas especies de preocupacion para la conservacion (p. ej.: tortugas marinas, peces vela y algunos tiburones) que se capturan en aguas mas someras (<100 m). De 2007 a 2011, examinamos las distribuciones de profundidad de anzuelos para 1154 conjuntos de linea larga (3, 406, 946 anzuelos) y registramos las capturas por posicion de anzuelo en 2462 conjuntos (7, 829, 498 anzuelos) en la pesqueria de linea larga de Samoa Americana. El 23% de los anzuelos tuvieron una profundidad establecida <100 m. Los individuos capturados en las 3 posiciones de anzuelo mas someras representaron el 18.3% de toda la captura accesoria. Analizamos los impactos hipoteticos de 25 de las especies mas abundantes en la pesqueria al eliminar las 3 posiciones mas someras de anzuelos bajo escenarios con y sin redistribucion de estos anzuelos a mayores profundidades. Las distribuciones variaron por especie: 45.5% (n = 10) de las tortugas marinas (Chelonia mydas), 59.5% (n = 626) de los peces espada (Tetrapturus angustirostris), 37.3% (n = 435) de los tiburones (Carcharhinus falciformis) y 42.6% (n = 150) de otra especie de tiburones (C. longimanus) fueron capturados en los 3 anzuelos mas someros. El 11% (n = 20, 435) de todo el atun y 8.5% (n = 10, 374) de albacoras fueron capturados en los 3 anzuelos mas someros. La eliminacion de anzuelos redujo el valor asentado por 1.6-9.2% y la redistribucion de los anzuelos incremento el promedio anual del valor asentado en relacion con el status quo por 5-11.7%. Con base en estos escenarios, la redistribucion de los anzuelos a mayores profundidades puede proporcionar una modificacion economica factible al equipo de linea larga que podria sustancialmente reducir la captura accesoria para una cantidad de especies vulnerables. Nuestros resultados sugieren que este metodo puede ser aplicable a conjuntos profundos de pesquerias pelagicas de linea larga a nivel mundial.

The STEER contains extensive mangroves and seagrass beds, along with coral reefs, lagoons, and cays. Within the watershed, however, are a large active landfill, numerous marinas, resorts, various commercial activities, an EPA Superfund Site, and residential areas, all of which have the potential to contribute pollutants to the STEER. As part of a project to develop an integrated assessment for the STEER, 185 chemical contaminants were analyzed in sediments from 24 sites. Higher levels of chemical contaminants were found in Mangrove Lagoon and Benner Bay in the western portion of the study area. The concentrations of polychlorinated biphenyls (PCBs), dichlorodiphenyltrichloroethane (DDT), zinc, copper, lead, and mercury were above a NOAA Effects Range-Low (ERL) sediment quality guideline at one or more sites, indicating impacts may be present in more sensitive species or life stages. Copper at one site in Benner Bay was above a NOAA Effects Range-Median (ERM) guideline indicating effects on benthic organisms were likely. The antifoulant boat hull ingredient tributyltin (TBT) was found at the third highest concentration in the history of NOAA's National Status and Trends (NS&T) Program, which monitors the nation's coastal and estuarine waters for chemical contaminants and bioeffects. The results from this project will provide resource managers with key information needed to make effective decisions affecting coral reef ecosystem health and gauge the efficacy of restoration activities.

Sample collection spanned the years prior to and following the implementation of management measures (1963-2010). Growth was compared pre- and post- population depletion and pre- and post- management to investigate the possibility of density-mediated shifts in age and growth parameters over time. There was no evidence of difference between periods for either sex. Additionally, bomb radiocarbon dating was used to determine the periodicity of band pair formation. Results support the traditional interpretation of annual band pairs up to approximately 11 years of age. After this time, vertebral counts considerably underestimate true age. Maximum validated ages were estimated to be between 38 and 42 years of age (an increase of 15 to 19 years over the band count estimates), confirming longevity to at least 42 years of age. Growth curves estimated using only validated data were compared to those generated using band pair counts. Logistic growth parameters derived from validated vertebral length-at-age data were L sub( infinity )=261.5 cm FL, L sub(o)=85.5 cm, t sub(o)=4.89 year and g=0.15 year super(-1) for the sexes combined. Revised estimates of age at maturity were 17.4 years for males and 17.6 years for females.

This way, the roles of ambient and storm-generated vorticity can be isolated. A new Lagrangian technique is employed in which material fluid volume elements are tracked to analyze the rearrangement of ambient vortex-line segments. This contribution is interpreted as barotropic vorticity. The storm-generated vorticity is treated as the residual between the known total vorticity and the barotropic vorticity.

When applied to observed soundings, all algorithms provide very reliable guidance on snow and rain (SN and RA). However, their skills for ice pellets and freezing rain (IP and FZRA) are comparatively low. Most misclassifications of IP are for FZRA and vice versa. Deeper investigation reveals that no method used in any of the algorithms to differentiate between IP and FZRA allows for clear discrimination between the two forms. The effects of model uncertainty are also considered. For SN and RA, these effects are minimal and each algorithm performs reliably. Conversely, IP and FZRA are strongly impacted. When the range of uncertainty is fully accounted for, their resulting wet-bulb temperature profiles are nearly indistinguishable, leading to very poor skill for all algorithms. Although currently available data do not allow for a thorough investigation, comparison of the statistics from only those soundings that are associated with long-duration, horizontally uniform regions of FZRA shows there are significant differences between these profiles and those that are from more transient, highly variable environments. Hence, a five-category (SN, RA, IP, FZRA, and IPFZRA mix) approach is advocated to differentiate between sustained regions of horizontally uniform FZRA (or IP) from more mixed environments.

There are more than a few instances in which the radar-measured radial velocities substantially exceed the estimated wind speeds associated with the enhanced Fujita (EF) scale rating assigned to a particular tornado. It is imperative, however, to understand what the radar data represent if one wants to compare radar observations to damage-based EF-scale estimates. A violent tornado observed by the rapid-scan, X-band, polarimetric mobile radar (RaXPol) on 31 May 2013 contained radar-relative radial velocities exceeding 135 m s1 in rural areas essentially devoid of structures from which damage ratings can be made. This case, along with others, serves as an excellent example of some of the complications that arise when comparing radar-estimated velocities with the criteria established in the EF scale. In addition, it is shown that data from polarimetric radars should reduce the variance of radar-relative radial velocity estimates within the debris field compared to data from single-polarization radars. Polarimetric radars can also be used to retrieve differential velocity, large magnitudes of which are spatially associated with large spectrum widths inside the polarimetric tornado debris signature in several datasets of intense tornadoes sampled by RaXPol.

The analysis uses regional extreme precipitation thresholds, quantitatively defined as the 99th and 99.9th percentile precipitation values of all wet-site days from 2001 to 2011 for each River Forecast Center (RFC) region, to evaluate QPF performance at multiple lead times. Five verification metrics are used: probability of detection (POD), false alarm ratio (FAR), critical success index (CSI), frequency bias, and conditional mean absolute error (MAEcond). Results indicate that extreme QPFs have incrementally improved in forecast accuracy over the 11-yr period. Seasonal extreme QPFs show the highest skill during winter and the lowest skill during summer, although an increase in QPF skill is observed during September, most likely due to landfalling tropical systems. Seasonal extreme QPF skill decreases with increased lead time. Extreme QPF skill is higher over the western and northeastern RFCs and is lower over the central and southeastern RFC regions, likely due to the preponderance of convective events in the central and southeastern regions. This study extends the NOAA HMT study of regional extreme QPF performance in the western United States to include the contiguous United States and applies the regional assessment recommended therein. The method and framework applied here are readily applied to any gridded QPF dataset to define and verify extreme precipitation events.

However, short-term biases within that period can exist, and application of the regression equations to new data may produce forecasts with short- or long-term biases. Because NWP models undergo changes over time, MOS forecasts can be biased because of these changes, and also possibly because of local environmental changes. These biases can be largely eliminated. In the decaying average method, a decay factor is used. This value affects not only the short- and long-term bias characteristics, but also other accuracy measures of the forecasts. This paper shows how different values of the decay factor affect MOS temperature and dewpoint forecasts, and the range of factors that would be appropriate for bias correcting those forecasts. Biases and other quality measures are shown for both cool and warm season samples before and after various values of the decay factor have been applied.

AN - 1532477550; 24821437 AB - Persistent organic pollutants (POPs) are toxic man-made chemicals that bioaccumulate and biomagnify in food webs, making them a ubiquitous threat to the marine environment. Although many studies have determined concentrations of POPs in top predators, no studies have quantified POPs in stranded cetaceans within the last 30 years around the Hawaiian Islands. A suite of POPs was measured in the blubber of 16 cetacean species that stranded in the tropical Pacific, including Hawai'i from 1997 to 2011. The sample set includes odontocetes (n=39) and mysticetes (n=3). Median (range) contaminant concentrations in ng/g lipid for the most representative species category (delphinids excluding killer whales [n=27]) are: 9650 (44.4-99,100) for ∑DDTs, 6240 (40.8-50,200) for ∑PCBs, 1380 (6.73-9520) for ∑chlordanes, 1230 (13.4-5510) for ∑toxaphenes, 269 (1.99-10,100) for ∑PBDEs, 280 (2.14-4190) for mirex, 176 (5.43-857) for HCB, 48.1 (0.063), but sex/age class influences were evident with adult males exhibiting greater contaminant loads than adult females and juveniles for ∑DDT, ∑PCBs, ∑CHLs, and mirex (p≤0.036). POP concentrations were lower in mysticetes than odontocetes for many compound classes (p≤0.003). p,p'-DDE/∑DDTs ratios were greater than 0.6 for all species except humpback whales, suggesting exposure to an old DDT source. These POP levels are high enough to warrant concern and continued monitoring. Published by Elsevier B.V.

AN - 1530953869; 24698170 AB - Concentrations of 28 trace elements (Li, Mg, Al, V, Cr, Mn, Fe, Co, Ni, Cu, Zn, Ga, As, Se, Rb, Sr, Mo, Ag, Cd, In, Sn, Sb, Cs, Tl, Hg, Pb, and Bi) in the livers of juvenile and adult American alligators inhabiting two central Florida lakes, Lake Apopka (LA), and Lake Woodruff National Wildlife Refuge (LW) and one lagoon population located in Merritt Island National Wildlife Refuge (MINWR; NASA), were determined. In juveniles from MINWR, concentrations of nine elements (Li, Fe, Ni, Sr, In, Sb, Hg, Pb and Bi) were significantly higher, whereas six elements (V, Fe, As, Sr, Hg and Bi) were elevated in adults (p<0.05) obtained from MINWR. Significant enrichment of some trace elements in adults, relative to juveniles, was observed at all three sampling areas. Specifically, Fe, Pb and Hg were significantly elevated in adults when compared to juveniles, suggesting age-dependent accumulation of these elements. Further, As, Se and Sn showed the same trend but only in animals collected from MINWR. Mean Fe concentrations in the livers of adults from LA, LW and MINWR were 1770 μg g(-1) DW, 3690 μg g(-1) DW and 5250 μg g(-1) DW, respectively. More than half of the adult specimens from LW and MINWR exhibited elevated hepatic Fe concentrations that exceed the threshold value for toxic effects in donkey, red deer and human. These results prompted us to express our concern on possible exposure and health effects in American alligators by some trace elements derived from NASA activities. Copyright © 2014 Elsevier Ltd.

AN - 1530953652; 24559935 AB - Anthropogenic stressors, including chemical contamination and temperature stress, may contribute to increased disease susceptibility in aquatic animals. Specifically, the organophosphate pesticide malathion has been detected in surface waters inhabited by threatened and endangered salmon. In the presence of increasing water temperatures, malathion may increase susceptibility to disease and ultimately threaten salmon survival. This work examines the effect of acute and sublethal exposures to malathion on ocean-type subyearling Chinook salmon held under two temperature regimes. Chinook salmon were exposed to malathion at optimal (11 °C) or elevated (19 and 20 °C) temperatures. The influence of temperature on the acute toxicity of malathion was determined by generating 96-h lethal concentration (LC) curves. A disease challenge assay was also used to assess the effects of sublethal malathion exposure. The malathion concentration that resulted in 50% mortality (LC50; 274.1 μg L(-1)) of the Chinook salmon at 19 °C was significantly less than the LC50 at 11 °C (364.2 μg L(-1)). Mortality increased 11.2% in Chinook salmon exposed to malathion at the elevated temperature and challenged with Aeromonas salmonicida compared to fish held at the optimal temperature and exposed to malathion or the carrier control. No difference in disease challenge mortality was observed among malathion-exposed and unexposed fish at the optimal temperature. The interaction of co-occurring stressors may have a greater impact on salmon than if they occur in isolation. Ecological risk assessments considering the effects of an individual stressor on threatened and endangered salmon may underestimate risk when additional stressors are present in the environment.

AN - 16388257; 16194 AB - PURPOSE: Two resource management plans for salmon and steelhead hatchery programs in Puget Sound are proposed. The resource management plans are the proposed frameworks through which the Washington Department of Fish and Wildlife and the Puget Sound treaty tribes would jointly manage Puget Sound salmon and steelhead hatchery programs. The plans include the foundation and general principles for adaptive management, which would guide decisions on a continuing basis as new information emerges. Appended to the resource management plans are 117 hatchery and genetic management plans describing 133 individual salmon and steelhead hatchery programs, including State, tribal, and one Federal program. The project area covered in this EIS includes Puget Sound freshwater and marine areas within the United States from the Canadian border south and west to exclude rivers and marine areas in the Strait of Juan de Fuca west of the Elwha River. Portions of 12 counties in Washington State are included. There are 133 salmon and steelhead hatchery programs in the project area described in 117 HGMPs. The programs are operated by WDFW and the Puget Sound treaty tribes, including one program that is operated by the U.S. Fish and Wildlife Service. These hatchery programs operate using 49 hatcheries and 34 net pens, and produce over 146 million salmon and steelhead per year. This draft EIS analyzes a no action alternative and three action alternatives. Under the no action alternative, NMFS would not evaluate and make take determinations for the Puget Sound hatchery RMPs and appended HGMPs. Alternative 2, the Proposed Action, consists of hatchery operations as proposed under the co-managers RMPs and appended HGMPs. NMFS would evaluate and make take determinations under the ESA section 4(d) rules, and adaptive management provisions in the RMPs would be applied. Hatchery production would be the same as under existing conditions, program sizes would meet conservation requirements for listed species, harvest benefits would continue, and adaptive management conservation measures would be applied to all programs to reduce risks to listed species. Compared to Alternative 2, Alternative 3 (Reduced Production) would provide greater conservation benefits to salmon and steelhead. Under this alternative, hatchery production for the purpose of harvest would be reduced 50 percent for all Chinook salmon, coho salmon, and steelhead programs in watersheds where watershed management strategies are oriented at protecting and recovering indigenous Chinook salmon populations where they still occur, and where management actions use the most locally adapted stock to re-establish natural production in watersheds in which suitable habitat exists but indigenous Chinook salmon populations no longer occur. Reductions would not occur in watersheds that may not have historically supported self-sustaining natural Chinook salmon populations. NMFS would evaluate and make take determinations under the ESA section 4(d) rules, and adaptive management provisions in the RMPs would be applied. Harvest benefits would be reduced but would continue, and conservation measures would be applied to all programs to reduce risks to listed species. Compared to Alternative 2, Alternative 4 (Increased Production) would provide more harvest benefits. Under this alternative, hatchery production would increase for programs where existing facility and funding capacity exists. No new facilities or water sources would be developed. The additional production would depend on the match of available hatchery capacity with the broodstock collection, spawning, incubation, and rearing needs of the fish species produced. Increases could occur for programs whose purposes include harvest and/or conservation. Increases in production would need to be in compliance with the ESA. NMFS would evaluate and make take determinations under the ESA section 4(d) rules, and adaptive management provisions in the RMPs would be applied. Program size and harvest benefits would increase, and conservation measures would be applied to all programs to reduce risks to listed species. POSITIVE IMPACTS: Amendments to the RMPs would benefit Chinook salmon, summer-run chum salmon, steelhead and bull trout, coco salmon, pink salmon, chum salmon, and sockeye salmon. Annual tribal harvest would be 1,321,156 fish and tribal gross economic values would be $9,148,467. Harvest would contribute to ceremonial and subsistence uses. NEGATIVE IMPACTS: There is potential for slight transfer of pathogens from hatchery-origin fish to wildlife. Hatchery weirs may restrict some wildlife movements. Hatchery program operations (e.g., use of screens and water) may have a negative effect on wildlife presence and mortality.

AN - 1547543154; 24949875 AB - Brevetoxins produced during algal blooms of the dinoflagellate Karenia are metabolized by shellfish into reduction, oxidation, and conjugation products. Brevetoxin metabolites comprising amino acid- and lipid conjugates account for a large proportion of the toxicity associated with the consumption of toxic shellfish. However, the disposition of these brevetoxin metabolites has not been established. Using intravenous exposure to C57BL/6 mice, we investigated the disposition in the body of three radiolabeled brevetoxin metabolites. Amino acid-brevetoxin conjugates represented by S-desoxy-BTX-B2 (cysteine-BTX-B) and lipid-brevetoxin conjugates represented by N-palmitoyl-S-desoxy-BTX-B2 were compared to dihydro-BTX-B. Tissue concentration profiles were unique to each of the brevetoxin metabolites tested, with dihydro-BTX-B being widely distributed to all tissues, S-desoxy-BTX-B2 concentrated in kidney, and N-palmitoyl-S-desoxy-BTX-B2 having the highest concentrations in spleen, liver, and lung. Elimination patterns were also unique: dihydro-BTX-B had a greater fecal versus urinary elimination, whereas urine was a more important elimination route for S-desoxy-BTX-B2, and N-palmitoyl-S-desoxy-BTX-B2 persisted in tissues and was eliminated equally in both urine and feces. The structures particular to each brevetoxin metabolite resulting from the reduction, amino acid conjugation, or fatty acid addition of BTX-B were likely responsible for these tissue-specific distributions and unique elimination patterns. These observed differences provide further insight into the contribution each brevetoxin metabolite class has to the observed potencies.

While many water quality parameters have been proposed to contribute to reef declines, little evidence exists conclusively linking specific water quality parameters with increased disease prevalence in situ. Here we report evidence from in situ coral health surveys confirming that chronic exposure to dredging-associated sediment plumes significantly increase the prevalence of white syndromes, a devastating group of globally important coral diseases. Coral health surveys were conducted along a dredging-associated sediment plume gradient to assess the relationship between sedimentation, turbidity and coral health. Reefs exposed to the highest number of days under the sediment plume (296 to 347 days) had two-fold higher levels of disease, largely driven by a 2.5-fold increase in white syndromes, and a six-fold increase in other signs of compromised coral health relative to reefs with little or no plume exposure (0 to 9 days). Multivariate modeling and ordination incorporating sediment exposure level, coral community composition and cover, predation and multiple thermal stress indices provided further confirmation that sediment plume exposure level was the main driver of elevated disease and other compromised coral health indicators. This study provides the first evidence linking dredging-associated sedimentation and turbidity with elevated coral disease prevalence in situ. Our results may help to explain observed increases in global coral disease prevalence in recent decades and suggest that minimizing sedimentation and turbidity associated with coastal development will provide an important management tool for controlling coral disease epizootics.

These forecasts were generated using output from an analytic-numerical Bayesian forecasting system (BFS) within a Monte-Carlo algorithm. Empirical distributions were estimated from the ensemble forecasts and compared with the analytic distributions output by the BFS. Using the maximum absolute difference as a measure of the quality of fit, it was shown that a single graph described the relationship between the ensemble size and the expected maximum absolute difference. Within the scope of the experiments, the graph was insensitive to forecast point, precipitation event (rain or no rain), and lead time. However, the graph only applied to probabilistic river stage forecast and probabilistic flood forecast, but not to probabilistic stage transition forecast, which is specified by a family of conditional predictive one-step transition distributions. Herein, further mathematical analysis of the estimation algorithm shows that, with a small modification, the single graph can be applied to all three types of forecasts.

Open ocean delta (super 30) Si observations indicate a surprisingly strong influence of the physical circulation on the large-scale marine Si distribution. Here, we present an ocean general circulation model simulation that deconvolves the physical and biogeochemical controls on the delta (super 30) Si distribution in the deep oceanic interior. By parsing dissolved Si into its preformed and regenerated components, we separate the influence of deep water formation and circulation from the effects of biogeochemical cycling related to opal dissolution at depth. We show that the systematic meridional delta (super 30) Si gradient observed in the deep Atlantic Ocean is primarily determined by the preformed component of Si, whose distribution in the interior is controlled solely by the circulation. We also demonstrate that the delta (super 30) Si value of the regenerated component of Si in the global deep ocean is dominantly set by oceanic regions where opal export fluxes to the deep ocean are large, i.e. primarily in the Southern Ocean's opal belt. The global importance of this regionally dynamic Si cycling helps explain the observed strong physical control on the oceanic delta (super 30) Si distribution, since most of the regenerated Si present within the deep Atlantic and Indo-Pacific Oceans is in fact transported into these basins by deep waters flowing northward from the Southern Ocean. Our results thus provide a mechanistic explanation for the observed delta (super 30) Si distribution that emphasizes the dominant importance of the Southern Ocean in the marine Si cycle.

Through a detailed case study, this article models how the field of political ecology can provide rich insight into such problems, and can help managers navigate the complex human dimensions of their work. Protracted disputes over salmon habitat restoration have earned the Skagit Valley of Washington State a reputation for being mired in intractable conflict. Goals of recovering salmon and protecting farmland are seemingly pitted against each other in competition for the same land. Using ethnographic methods and a political ecology framework, I argue that social hierarchies and mistrusts, conflicting senses of place, prevailing cultural narratives, and legal and institutional constraints contribute to the dispute over habitat restoration. Closer attention to sociocultural factors such as these may help managers identify and implement locally supported recovery opportunities, facilitate cooperation among stakeholders, improve agency approaches, and reframe management agendas to better address collective needs. I conclude that ecosystem recovery requires not only the renewal of ecological health, but also the renewal of social trust and cooperation, new cultural narratives, and a richer language that can capture its complex social realities.

This included invertebrates and vertebrates distributed between Maine and Florida, with a few species ranging across all these states and some ranging into the Gulf of Mexico and the Canadian Maritimes. The effects of larval dispersal or mixing of adults in the marine environment were evident. Marine and catadromous spawners were recognized and treated as a unit stock (e.g., northern shrimp Pandalus borealis, American Eel Anguilla rostrata, Atlantic menhaden Brevoortia tyrannus, Bluefish Pomatomus saltatrix, Tautog Tautoga onitis), a metapopulation (American lobster Homarus americanus, Atlantic Herring Clupea harengus), or two stocks, north and south of Cape Hatteras, a major biogeographic boundary, (Black Sea Bass Centropristis striata, Scup Stenotomus chrysops, Red Drum Sciaenops ocellatus, Summer Flounder Paralichthys dentatus). Estuarine and anadromous spawners were structured and managed at a finer spatial scale (horseshoe crab Limulus polyphemus, Atlantic Sturgeon Acipenser oxyrinchus, American Shad Alosa sapidissima and the river herrings Blueback Herring A. aestivalis and Alewife A. pseudoharengus, and Spotted Seatrout Cynoscion nebulosus). A broad suite of stock identification methods have been applied to ASMFC species and reviewed here in five categories: life history traits, other phenotypic traits, genetic traits, natural marks, and applied marks. An interdisciplinary mix of methods has been achieved for a few species (Striped Bass Morone saxatilis, Winter Flounder Pseudopleuronectes americanus), but only a few or no stock identification methods have been applied to others (Spiny Dogfish Squalus acanthias, Hickory Shad A. mediocris, Spot Leiostomus xanthurus, Spanish Mackerel Scomberomorus maculatus). Clinal phenotypic variation has contributed to several long-standing debates about stock structure; some of these have been recently reevaluated as a unit stock (Atlantic Croaker Micropogonias undulatus, Weakfish Cynoscion regalis), and others are still debated. For some ASMFC species, other priorities (e.g., bycatch) dominate the uncertainty of the assessment or management process. Otherwise, stock identification remains a research priority for most of these species. Continued research of this subject should consider (1) research priorities tabulated by ASMFC review panels, (2) strategic use of interdisciplinary stock identification methods, (3) use of experiments or reaction norms to separate phenotypes from genotypes, (4) genetic surveys at a seascape scale, (5) demonstration of contingent (nongenetic) structure and its implications for management, and (6) simulation modeling. Obstacles to adopting finer-scale structure into assessments or management of ASMFC fisheries include: (1) multiple stock units are apparent but boundaries are not clear, (2) monitoring requirements for smaller areas or for mixed-stock catches are not cost effective, or (3) mixing rates within a metapopulation or across biogeographic boundaries are poorly described.

Growth during the first summer is vitally important for juvenile Chinook Salmon, as it influences not only life history decisions (to smolt or not to smolt) but also subsequent river and ocean survival. Using Ecopath with Ecosim, we developed a food web model for a representative stream in the Salmon River basin, Idaho, to evaluate potential species-specific and food web effects of three management strategies: (1) adding salmon carcasses or carcass analogs to promote primary production and detrital availability that were lost due to declining salmon returns; (2) removal of nonnative Brook Trout Salvelinus fontinalis, which are competitors with and predators on juvenile Chinook Salmon; and (3) stocking hatchery Chinook Salmon into streams to supplement wild production. Overall, juvenile Chinook Salmon responded strongly to increases in basal resources. Removal of Brook Trout had little effect on potential production for juvenile Chinook Salmon, but the responses of sculpins Cottus spp. were strong, primarily due to the sculpins' high degree of dietary overlap with and predation by Brook Trout. Supplementation with hatchery-origin juveniles depressed the production of wild juvenile Chinook Salmon, especially at the densities commonly applied to streams in this region. Our results suggest that efforts to enhance basal resources are likely to be the most effective in promoting the production of juvenile Chinook
