TY - JOUR T1 - A fresh look at the geologic evolution of Kingman Reef and Palmyra Atoll, U.S. Line Islands AN - 1707526290; 2015-080279 AB - Extended continental shelf (ECS) interest has provided a vehicle for renewed scientific study of the geologic framework of the U.S. Line Islands. In support of ECS studies, GLORIA sidescan sonar imagery has been refreshed and re-released. New multibeam bathymetry and backscatter data and a compilation of bathymetric tracks of opportunity enhance the credibility of new backscatter interpretations. Two-channel seismic reflection data collected during the GLORIA program in 1991 have been reprocessed and compiled into a digital database and have yielded a new understanding of sediment distribution and basement morphology within the 200 nautical mile exclusive economic zone (EEZ) surrounding Kingman Reef and Palmyra Atoll. Kingman Reef and Palmyra Atoll are small islands today. We infer that they are the last subaerial remnants of what was once a complex volcanic island, made up of no fewer than 8 different volcanic centers and spanning roughly 200 km in total diameter. Edifice heights above the immediately surrounding volcanic basement exceed 3000 m, and in several cases exceed 4000 m. Voluminous sediment accumulations flanking these now-submerged and significantly buried edifices point to their past existence as shallow-water or emergent volcanic systems capable of producing large quantities of volcaniclastic as well as carbonate sediment quite different from the thinner layer of pelagic sediment blanketing the adjacent central Pacific deep sea floor. The sediment pond east of Palmyra Atoll, in a perched basin near the center of this ancient complex, exceeds 1200 m in thickness. The Kingman-Palmyra region today is a showcase of mass transport features, with rugged erosional topography on steep volcanic flanks, a collapsed or eroding carbonate platform covering part of the central complex, and wide, sinuous leveed channels sweeping predominantly toward the north, carrying sediment away from the remnant high and out onto the deep sea floor to the east of the Line Islands platform.

S. Extended Continental Shelf Project AN - 1707525761; 2015-080288 AB - The U.S. Extended Continental Shelf (ECS) Project is a multi-agency collaboration led by the U.S. Department of State whose mission is to establish the full extent of the continental shelf of the United States consistent with international law. Since 2003, the U.S. has been actively collecting bathymetric, seismic, and other geophysical data and geologic samples required to delineate its outer limits in accordance with Article 76 of the UN Convention on the Law of the Sea. In 2007, the U.S. ECS Task Force designated the National Geophysical Data Center (NGDC) to serve as both the Data Management lead and the Data Archive and Integration Center for the U.S. ECS Project. NGDC, one of three National Oceanic and Atmospheric Administration (NOAA) Offices active in the ECS Project, has the primary responsibility to provide a common infrastructure and a means to integrate the data supporting, and products resulting from ECS analysis. One of the key challenges in the ECS project is the requirement to track the provenance of data and derived products. Final ECS analyses may result in hundreds of points that define a new maritime boundary that is our extended continental shelf. These points will be developed in a rigorous process of analysis encompassing potentially thousands of raw datasets and derived products. NGDC has spent the past two years planning, designing, and partially implementing the Information Management System (IMS), a highly functional, interactive software system that serves as the master database for the ECS Project. The purpose of this geospatial database is to archive, access, and manage the primary data, derivative data and products, associated metadata, information and decisions that will form the U.S. submission. The IMS enables team members to manage ECS data in a consistent way while maintaining institutional memory and the rationale behind decisions. The IMS contains two major components: First, a catalog that acts as the interface to the IMS by organizing the data and products and assisting in populating submission document templates. Second, a web map viewer that geospatially displays the data and products. These components enable dispersed team members to manage ECS data consistently, to track the provenance of data and derived products used in the analyses, and to display analyses using a dynamic web map service. This poster illustrates the importance of data management within the ECS project and focuses on the implementation of the IMS and its use supporting the final determination of a new maritime boundary for the U.S. JF - American Geophysical Union Fall Meeting AU - Lim, Elliot AU - Henderson, Jennifer F AU - Warnken, Robin R AU - McLean, Susan J AU - Varner, Jesse D AU - McQuinn, Evan AU - LaRocque, John AU - Anonymous Y1 - 2013/12// PY - 2013 DA - December 2013 SP - Abstract OS13B EP - 1709 PB - American Geophysical Union, Washington, DC VL - 2013 KW - 07:Oceanography UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1707525761?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=Data+management+supporting+the+U.+S.+Extended+Continental+Shelf+Project&rft.au=Lim%2C+Elliot%3BHenderson%2C+Jennifer+F%3BWarnken%2C+Robin+R%3BMcLean%2C+Susan+J%3BVarner%2C+Jesse+D%3BMcQuinn%2C+Evan%3BLaRocque%2C+John%3BAnonymous&rft.aulast=Lim&rft.aufirst=Elliot&rft.date=2013-12-01&rft.volume=2013&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 2013 fall meeting N1 - Copyright - GeoRef, Copyright 2015, American Geosciences Institute.

These backscatter data have been used to identify gas plumes associated with seafloor methane seeps as part of previous investigations in the Gulf of Mexico and at Blake Ridge. Here, we use QPS Fledermaus Midwater software to analyze over 200,000 km2 of multibeam data acquired on the continental slope and outer shelf of the US Atlantic margin in 2011, 2012, and 2013. Preliminary application of this analytical methodology in late 2012 revealed the first deepwater (> 1000 m water depth) cold seeps found on the US Atlantic margin north of Cape Hatteras as well as 47 new upper slope seeps (http://www.noaanews.noaa.gov/stories2012/20121219_gas_seeps.html). In this new analysis, we identify over 500 water column backscatter anomalies (WCA) originating at the seafloor and extending to various heights in the water column between Cape Hatteras and the Nantucket margin. Data set quality control was achieved through secondary independent analysis of all WCA backscatter records by a highly experienced researcher who assigned a quality factor to each anomaly. Additionally, a subset of the data was analyzed using a Matlab code designed to automatically detect WCA in backscatter data. These quality-control and WCA comparison procedures provide confidence that several hundred of the WCA are robust picks. The observed WCA are structurally consistent with previously confirmed gas bubble plumes, being vertically elongate, rooted at the seafloor, and deflected by currents. They are not structurally consistent with other common WCA such as schooling or swarming organisms. Additionally, the bases of selected WCA that were identified in this analysis have recently been visually and acoustically confirmed to be associated with emission of gas bubbles from the seafloor by the NOAA remotely operated vehicle Deep Discoverer. The physical characteristics and location of the WCA suggest that they are likely methane plumes, although this has yet to be confirmed by direct gas sampling. The WCA occur both in isolation and in clusters, and repeated observation of select seep fields indicated intermittent WCA identifications that could not be explained by uncertainties in the spatial resolution of the data. Thus, some of the WCA appear to exhibit ephemerality on time scales of hours to days. This research was undertaken while the lead author was a NOAA Hollings Scholar intern with the NOAA Office of Ocean Exploration and Research.

Acoustic imagery indicates that these vertically elongate methane plumes extend hundreds of meters above the seafloor and are often deflected by ocean currents. Visual and acoustic observation of the base of select plumes by the NOAA remotely operated vehicle (ROV) Deep Discoverer in 2013 confirmed that they are generated by emission of gas bubbles at seafloor seeps. Prior to this discovery, the only observed cold seeps on the central and northern extents of the US Atlantic margin were at shallow water depths in Baltimore Canyon, and no deepwater (>1000 m) seeps were known to exist. The new seeps are observed at depths ranging from 100 m on the Nantucket Shelf to 1400 m in the vicinity of Norfolk, Baltimore, and Veatch Canyons. The seeps occur in isolation as well as in clusters, and particularly high seep concentrations are observed in the upper portions of Hudson Canyon. Along-margin seep distribution is not uniform and higher overall seep concentrations are observed north of Veatch Canyon and south of Wilmington Canyon, with substantially fewer seep occurrences on the intervening part of the Mid-Atlantic Bight. Lithology (e.g., coarse-grained vs. fine-grained sediment), underlying geology, and shelf-slope morphology appear to be correlated with the spatial distribution of cold seeps along the margin. Numerous shallow water ( nearly equal 500 m) seep locations are roughly coincident with seafloor pockmark features identified by D. Brothers (personal communication) and are proximal to the upslope extent of the gas hydrate stability zone (GHSZ). Multiple deepwater seep locations are identified within the GHSZ, but do not yet appear to be associated with salt diapirism or any other geological phenomena with the capacity to drive active methane expulsion at the seafloor. Repeat acoustic and video surveys at an nearly equal 500 m (super 2) seep field south of Nantucket Island demonstrated that some seeps are characterized by continuous gas emission, whereas other proximal seeps exhibit episodic gas emission with a temporal variability on the order of hours to days. While significant ephemerality of methane emission at the scale of individual plumes has been verified, ROV imagery of massive, but isolated, patches of authigenic carbonate and well-developed chemosynthetic communities suggest that emission of methane at the scale of the seep field has been persistent over hundreds to thousands of years.

Responses to large tropical volcanic eruptions are a key focus area. Paleoclimatology offers a unique vehicle to extend the study of these responses over much longer periods than those available from instrumental data. In this work, we present a set of annually-resolved, late-winter temperature responses in temperate western North America over 1500-1980 CE, and evaluate, from a regional perspective, evidence that large tropical eruptions show a tendency towards an initial El Nino (EN) response followed by a delayed La Nina (LN) (c.f. Li et al., 2013, DOI:10.1038/NCLIMATE1936). The proxy information are primarily tree ring widths and some ring density data from the target reconstruction region (30-55 degrees N, 95-130 degrees W) and northern Mexico, which are calibrated and validated against 5x5 degrees gridded instrumental temperature data. Calibration uses an optimized form of principal components spatial regression, and well-validated reconstructions (for both the regional average and spatially) were able to be achieved for the February-March (FM) period. The reconstructions are additionally validated by their capacity to resolve known regional composite EN and LN late-winter temperature patterns. Superposed epoch analysis (SEA, n=13) was used to determine the composite responses for a sequence of post-volcanic-event years. Results do not show an initial EN-like regional response, but do show LN-like patterns in post-event Years 3-5. The correlations of the SEA patterns for Years 3-4 with the LN regional composite are significant based on correlations observed in ensembles of random-event-year SEAs, which account for the strong regional ENSO teleconnection. Relative homogeneity of the SEA response for each post-event year is evaluated as the amplitude (signal) of the SEA composite relative to its variance (noise) across events. Relative to the same metric observed from the random-event-year SEAs, these S/N ratios are significant in the portions of the domain with the strongest anomalies in Years 1-4, especially Year 3, and then tend towards uniformly low/insignificant values indicating lessening entrainment across individual events as time progresses. Post-event 500 mb FM geopotential height composites from the 20th Century Reanalysis (1871-2011 CE, n=5) are generally consistent with the SEA temperature patterns. In particular, the Year 1 pressure composite does not cohere with ENSO-related pressure composites, consistent with the very weak/weak pattern correlations this year shows with the EN/LN temperature composites; and the pressure composite in North America and the adjacent Pacific and Atlantic regions in Year 3 is strongly LN-like, consistent with the relatively strong pattern correlation this year shows with the LN temperature composite and the S/N results. The weakening entrainment across eruptions as post-event time progresses from Year 3 in the S/N results is also consistent with more variable pressure composites noted after that time. The LN-like response in Years 3-5 exhibits a slight shift of its southern warm anomaly to the north and west relative to composite LN conditions, which is isolated as a specifically post-eruption feature.

Current tsunami modeling techniques usually ignore this time-dependent behavior in tsunami sources by assuming an instantaneous initial deformation field. Initial attempts to include time-dependent rupture behavior have motivated scientists to simulate this phenomenon as a series of instantaneous changes in the sea-floor. The present study investigates the effect of dynamic ground motion rupture on tsunami generation by including the time-dependent initial conditions in the derivation of the linear shallow-water wave equations. We then study the sensitivity of initial water surface deformation to time-dependent seafloor rupture by performing a parametric study of varying speed and rupture direction, while assuming a monotonic deformation from an initial pre-rupture state to a post-rupture final state. Numerical results for some selected scenarios are validated by comparing with analytical solutions of the non-homogeneous linear shallow-water equations.

Progressive deepening of these gateways and northward migration of Australia through the Eocene impacted global ocean circulation. We present middle to late Eocene ( nearly equal 36-40 Ma) benthic foraminiferal stable isotope (delta 18O, delta 13C) records from ODP Site 1090 that extend published late Eocene-early Oligocene records (Pusz et al. 2011). Comparisons with published isotope records highlight that the deep ( nearly equal 3000 m) eastern and western South Atlantic (Sites 699 (Mead et al. 1993) and 1090) was warmer than the shallower ( nearly equal 1500-2500 m) Southern Ocean Sites 689 (Diester-Haass and Zahn, 1996; Bohaty et al., 2012). The divergence in the delta 18O records began in the late middle Eocene and continued through the late Eocene, as the Drake and Tasman gateways progressively deepened, and Australia moved northward. We speculate that these paleogeographic changes resulted in the development of circulation analogous to the modern Supergyre, which transported warm Indian and Pacific water westward into the South Atlantic and cooler South Atlantic water eastward into the Pacific Ocean via the Tasman Seaway, and acted as a barrier that prevented subtropical water from flowing to high southern latitudes. At the same time, a significant carbon isotopic (delta 13C) offset developed between Site 1090 (values nearly equal 0.7 ppm lower) and other sites from nearly equal 37.5 to 34 Ma, coinciding with onset of elevated opaline silica (Diekmann et al. 2004), barite, carbonate, and phosphorous (Anderson and Delaney 2005) deposition at Site 1090; these changes are consistent with enhanced primary productivity at the northern edge of the developing polar front, consistent with model predictions for the effects of proto-ACC development (Heinze and Crowley, 1997; Toggweiler and Bjornsson, 2000).

But a rather obvious argument can be made that the upwelling along the ACC is only the first stage of closure. The water upwelled south of the ACC is carried back across the ACC in the surface Ekman layer and combines with thermocline waters from the subtropical gyres to form a series of subantarctic water masses that are emplaced below the thermocline along the northern edge of the ACC. But these water masses are cool and fresh while the precursors of NADW are known to be warm and salty. According to the results from a new paper, the transformation is made in the coastal upwelling zones off Namibia and northwest Africa in the Atlantic and off Costa Rica and Peru in the Pacific. Basically, the upwelling in these areas draws the cool and fresh subantarctic water up to the surface in the tropics where it can then become warm and salty on its way back to the North Atlantic. Unfortunately, this second stage of closure tends not to occur in ocean circulation models because the coastal upwelling regions are barely resolved. In this presentation I will examine how the coastal upwelling alters the ocean's overturning and will speculate about how it changes the sensitivity of the overturning to ocean gateways.

The region of tsunami origin is as important as the expected magnitude and the predicted inundation for understanding tsunami hazard. The NOAA Center for Tsunami Research has developed high-resolution tsunami models capable of predicting tsunami arrival time and amplitude of waves at each location. These models have been used to conduct tsunami hazard assessments to assess maximum impact and tsunami inundation for use by local communities in education and evacuation map development. Hazard assessment studies conducted for Los Angeles, San Francisco, Crescent City, Hilo, and Apra Harbor are combined with results of tsunami forecast model development at each of seventy-five locations. Complete hazard assessment, identifies every possible tsunami variation from a pre-computed propagation database. Study results indicate that the Eastern Aleutian Islands and Alaska are the most likely regions to produce the largest impact on the West Coast of the United States, while the East Philippines and Mariana trench regions impact Apra Harbor, Guam. Hawaii appears to be impacted equally from South America, Alaska and the Kuril Islands.

Extensive destruction, erosion, sediment transport and deposition resculpted coastal landscape within few minutes along hundreds of kilometers of the Central Chile, in 2010, and the Northeast coast of Japan, in 2011. In the central coast of Chile, we performed a post-tsunami survey a week after the tsunami due to access restrictions. Our observations focus on the inundation and geomorphic effects of the 2010 tsunami and included an air reconnaissance flight, analysis of pre- and post-event low fly air-photographs and Google Earth satellite images, together with ground reconnaissance and mapping in the field, including topographic transects, during a period of 13 days. Eyewitness accounts enabled us to confirm our observations on effects produced by the tsunami along approximately 500 km along the coastline landscape in central Chile For the Tohoku case study, we assessed in a day tsunami inundation distances and runup heights using satellite data (very high resolution satellite images from the GeoEye1 satellite and from the DigitalGlobe worldview through the Google crisis response project, SRTM and ASTER GDEM) of the Tohoku region, Northeast Japan. Field survey data by Japanese, other international scientists and us validated our results. The rapid assessment of damage using high-resolution images has proven to be an excellent tool neccessary for efficient postsunami surveys as well as for rapid assessment of areas with access restrictions. All countries, in particular those with less access to technology and infrastructure, can benefit from the use of freely available satellite imagery and DEMs for an initial, pre-field survey, rapid estimate of inundated areas, distances and runup, tsunami effects in the coastal geomorphology and for assisting in hazard management and mitigation after a natural disaster. These data provide unprecedented opportunities for rapid assessment and to describe both damage and how tsunamis impacted the coastal geomorphology.

Wave amplitudes reached almost 10 centimeters in deep water, as recorded at DART buoy 44402 and 20 to 30 centimeters at coastal tide gauges in Rhode Island, Massachusetts, New York and New Jersey. Smaller signatures were seen in tide gauges as far away as Bermuda and Puerto Rico. There seems to be circumstantial evidence indicating a meteorological origin for the June 13 event, however, that explanation is less compelling for the event of April 11. Moreover, travel time contours trace the origin of both perturbations back to an area located in the vicinity of Hudson Canyon. A preliminary bathymetric survey of the walls of the canyon failed to locate any recent landslide evidence, and forward modeling of potential landslides in the canyon indicates that a larger source would have been needed to generate the kind of wavelengths recorded during this event. A model using a source just shoreward of the canyon shows arrival times that agree well with data at both the DART buoy and the tide gauges, but fails to reproduce some large amplitude waves within Delaware Bay that may, indeed, be atmospherically forced. The present study tries to identify possible landslide sources of this non-seismic tsunami, primarily located along the continental break outside of the Hudson Canyon. Failure to identify any such sources will strengthen the hypothesis of a meteotsunami. Positive identification of potential landslide sources may open up additional lines of investigation as to the real source of the event.

AN - 1703686961; 2015-078013 AB - The tragedies of 2004 Sumatra and 2011 Japan tsunamis exposed the limits of our knowledge in preparing for devastating tsunamis. The 1,100-km coastline of the Pacific coast of North America has tectonic and geological settings similar to Sumatra and Japan. The geological records unambiguously show that the Cascadia fault had caused devastating tsunamis in the past and this geological process will cause tsunamis in the future. Hypotheses of the rupture process of Cascadia fault include a long rupture (M9.1) along the entire fault line, short ruptures (M8.8-M9.1) nucleating only a segment of the coastline, or a series of lesser events of M8+. Recent studies also indicate an increasing probability of small rupture occurring at the south end of the Cascadia fault. Some of these hypotheses were implemented in the development of tsunami evacuation maps in Washington and Oregon. However, the developed maps do not reflect the tsunami impact caused by the most recent updates regarding the Cascadia fault rupture process. The most recent study by Wang et al. (2013) suggests a rupture pattern of high-slip patches separated by low-slip areas constrained by estimates of coseismic subsidence based on microfossil analyses. Since this study infers that a Tokohu-type of earthquake could strike in the Cascadia subduction zone, how would such an tsunami affect the tsunami hazard assessment and planning along the Pacific Coast of North America? The rapid development of computing technology allowed us to look into the tsunami impact caused by above hypotheses using high-resolution models with large coverage of Pacific Northwest. With the slab model of MaCrory et al. (2012) (as part of the USGS slab 1.0 model) for the Cascadia earthquake, we tested the above hypotheses to assess the tsunami hazards along the entire U.S. West Coast. The modeled results indicate these hypothetical scenarios may cause runup heights very similar to those observed along Japan's coastline during the 2011 Japan tsunami,. Comparing to a long rupture, the Tohoku-type rupture may cause more serious impact at the adjacent coastline, independent of where it would occur in the Cascadia subduction zone. These findings imply that the Cascadia tsunami hazard may be greater than originally thought.

Within the NTHMP are several subcommittees responsible for complimentary aspects of tsunami assessment, mitigation, education, warning, and response. The Mapping and Modeling Subcommittee (MMS) is comprised of state and federal scientists who specialize in tsunami source characterization, numerical tsunami modeling, inundation map production, and warning forecasting. Until September 2012, much of the work of the MMS was authorized through the Tsunami Warning and Education Act, an Act that has since expired but the spirit of which is being adhered to in parallel with reauthorization efforts. Over the past several years, the MMS has developed guidance and best practices for states and territories to produce accurate and consistent tsunami inundation maps for community level evacuation planning, and has conducted benchmarking of numerical inundation models. Recent tsunami events have highlighted the need for other types of tsunami hazard analyses and products for improving evacuation planning, vertical evacuation, maritime planning, land-use planning, building construction, and warning forecasts. As the program responsible for producing accurate and consistent tsunami products nationally, the NTHMP-MMS is initiating a multi-year plan to accomplish the following: 1) Create and build on existing demonstration projects that explore new tsunami hazard analysis techniques and products, such as maps identifying areas of strong currents and potential damage within harbors as well as probabilistic tsunami hazard analysis for land-use planning. 2) Develop benchmarks for validating new numerical modeling techniques related to current velocities and landslide sources. 3) Generate guidance and protocols for the production and use of new tsunami hazard analysis products. 4) Identify multistate collaborations and funding partners interested in these new products. Application of these new products will improve the overall safety and resilience of coastal communities exposed to tsunami hazards.

The method (called Short-term Inundation Forecast for Tsunamis--SIFT) uses DART real-time data to improve the accuracy of coastal tsunami forecast, when compared with just the seismic data-based assessment. The main goal of the forecast system is to forecast flooding due to tsunami wave at specific coastal locations. Other tsunami parameters are also computed to estimate overall hazard at a given location for a specific tsunami event. Knowing the accuracy of the forecast is extremely important for making right decisions throughout tsunami warnings procedures. During operational testing of the system a comprehensive analysis of accuracy of the system has been performed. The presentation will present the accuracy analysis of the tsunami forecast and implications for future development and improvements of tsunami forecasting.

While most have been generated by local earthquakes, distant generated tsunamis can also affect the region. For example, waves from the 1755 Lisbon earthquake and tsunami were observed in Cuba, Dominican Republic, British Virgin Islands, as well as Antigua, Martinique, Guadalupe and Barbados in the Lesser Antilles. Since 1500, at least 4484 people are reported to have perished in these killer waves. Although the tsunami generated by the 2010 Haiti earthquake claimed only a few lives, in the 1530 El Pilar, Venezuela; 1602 Port Royale, Jamaica; 1918 Puerto Rico; and 1946 Samana, Dominican Republic tsunamis the death tolls ranged to over a thousand. Since then, there has been an explosive increase in residents, visitors, infrastructure, and economic activity along the coastlines, increasing the potential for human and economic loss. It has been estimated that on any day, upwards of more than 500,000 people could be in harm's way just along the beaches, with hundreds of thousands more working and living in the tsunamis hazard zones. Given the relative infrequency of tsunamis, exercises are a valuable tool to test communications, evaluate preparedness and raise awareness. Exercises in the Caribbean are conducted under the framework of the UNESCO IOC Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS) and the US National Tsunami Hazard Mitigation Program. On March 23, 2011, 34 countries and territories participated in the first CARIBE WAVE/LANTEX regional tsunami exercise, while in the second exercise on March 20, 2013 a total of 45 countries and territories participated. 481 organizations (almost 200 more than in 2011) also registered to receive the bulletins issued by the Pacific Tsunami Warning Center (PTWC), West Coast and Alaska Tsunami Warning Center and/or the Puerto Rico Seismic Network. The CARIBE WAVE/LANTEX 13 scenario simulated a tsunami generated by a magnitude 8.5 earthquake originating north of Oranjestad, Aruba in the Caribbean Sea. For the first time earthquake impact was included in addition to expected tsunami impact. The initial message was issued by the warning centers over the established channels, while different mechanisms were then used by participants for further dissemination. The enhanced PTWC tsunami products for the Caribbean were also made available to the participants. To provide feedback on the exercise an online survey tool with 85 questions was used. The survey demonstrated satisfaction with exercise, timely receipt of bulletins and interest in the enhanced PTWC products. It also revealed that while 93% of the countries had an activation and response process, only 59% indicated that they also had an emergency response plan for tsunamis and even fewer had tsunami evacuation plans and inundation maps. Given that 80% of those surveyed indicated that CARIBE WAVE should be conducted annually, CARIBE EWS decided that the next exercise be held on March 26, 2014, instead of waiting until 2015.

One of three primary requirements of the grant was to make improvements to tsunami warning messages of the NWS' two Tsunami Warning Centers- the West Coast/Alaska Tsunami Warning Center (WCATWC) in Palmer, Alaska and the Pacific Tsunami Warning Center (PTWC) in Ewa Beach, Hawaii. We conducted focus group meetings with a purposive sample of local, state and Federal stakeholders and emergency managers in six states (AK, WA, OR, CA, HI and NC) and two US Territories (US Virgin Islands and American Samoa) to qualitatively assess information needs in tsunami warning messages using WCATWC tsunami messages for the March 2011 Tohoku earthquake and tsunami event. We also reviewed research literature on behavioral response to warnings to develop a tsunami warning message metric that could be used to guide revisions to tsunami warning messages of both warning centers. The message metric is divided into categories of Message Content, Style, Order and Formatting and Receiver Characteristics. A message is evaluated by cross-referencing the message with the operational definitions of metric factors. Findings are then used to guide revisions of the message until the characteristics of each factor are met. Using findings from this project and findings from a parallel NWS Warning Tiger Team study led by T. Nicolini, the WCATWC implemented the first of two phases of revisions to their warning messages in November 2012. A second phase of additional changes, which will fully implement the redesign of messages based on the metric, is in progress. The resulting messages will reflect current state-of-the-art knowledge on warning message effectiveness. Here we present the message metric; evidence-based rational for message factors; and examples of previous, existing and proposed messages.

AN - 1700099093; 2015-070512 AB - Some 500 active vent sites, both focused and diffuse, have now been located along spreading centers by either visual confirmation or instrumental detection of the discharging plume. Discovery of the large majority of these sites was made easier by high-volume discharge of particle-laden plumes. These observations led to estimates (as can be derived from the InterRidge Vents Database) of site frequency from approximately E0.5-5/100 km, generally increasing with spreading rate. Over the last decade, however, the increasing use of oxidation-reduction potential (ORP (mV)) (aka Eh) sensors capable of detecting minute concentrations of reduced hydrothermal chemicals (e.g., Fe (super +2) , sulfides, Mn (super +2) , H (sub 2) , and others) suggests that these frequency estimates may be far too conservative. This hypothesis is consistent with earlier results from a few large-scale, high-resolution camera tows on some EPR segments. ORP data provide two important advantages for site identification not available with other commonly used continuously recording sensors: (1) detection of low-temperature, particle-scarce plumes, and (2) detection of reduced chemical species with very short residence times, thus increasing the location specificity of the discharge source. Here, we present high-resolution distributions of ORP anomalies observed in past plume surveys along the Eastern Lau Spreading Center (19.5 degrees -22.5 degrees S) in 2004 and 2008, the Galapagos Spreading Center (94.6 degrees -86 degrees W) in 2005/6 and 2011, as well as new data (2011) from the East Pacific Rise (9 degrees -10 degrees N). Except for the 2011 GSC data (a standard CTD tow-yo), all data were collected during continuous horizontal tows of ORP sensors at various depths < approximately 120 m above the seafloor. We used two approaches to verify that ORP anomalies were authentic hydrothermal signals and not (especially in the case of small anomalies) produced by some other transient chemical anomaly. First, on the 2008 ELSC and 2011 EPR tows we compared temperature (Delta T) and ORP (Delta ORP) data from the two deepest sensors on each tow. Although temperature anomalies (Delta T degrees C) rarely exceeded 0.1 degrees C, all sensors showed a positive correlation between Delta ORP and Delta T (ELSC, 1569 & 1493 mV/ degrees C, r (super 2) approximately 0.4; EPR, 1760 & 986 mV/ degrees C, r (super 2) approximately 0.6). Second, comparison of tows conducted days and years apart regularly detected anomalies at the same locations. While an exact enumeration of all sites is impossible from water column data alone, we estimate approximately 20 sites along 115 km of the EPR (17.5/100 km), approximately 40 sites along 425 km of the ELSC (9.4/100 km), and approximately 50 sites along 900 km of the GSC (5.5/100 km). Anomalies < approximately 1 km apart are considered as from the same source. For the EPR and ELSC surveys, these frequencies are considerably higher than expected for ridges of similar spreading rate. The higher frequencies reported here more closely match results from visual vent-mapping along 128 km of the EPR at 9 degrees -10 degrees N and 17 degrees -18 degrees S. The lower site frequency along the GSC is consistent with plume data on other ridges influenced by hotspot thermal anomalies. The aggregate mass flux of discharges from numerous small sites is unknown, and could be significant; in any case, these sites may be vital oases for hydrothermal biota.

Such outreach and education is critical for coastal populations nearest an earthquake since they may not get an official warning before a tsunami reaches them and will need to know what to do when they feel strong shaking. Those who live far enough away to receive useful official warnings and react to them, however, can also benefit from PTWC's education and outreach efforts. They can better understand a tsunami warning message when they receive one, can better understand the danger facing them, and can better anticipate how events will unfold while the warning is in effect. The same holds true for emergency managers, who have the authority to evacuate the public they serve, and for the news media, critical partners in disseminating tsunami hazard information. PTWC's YouTube channel supplements its formal outreach and education efforts by making its computer animations available 24/7 to anyone with an Internet connection. Though the YouTube channel is only a month old (as of August 2013), it should rapidly develop a large global audience since similar videos on PTWC's Facebook page have reached over 70,000 viewers during organized media events, while PTWC's official web page has received tens of millions of hits during damaging tsunamis. These animations are not mere cartoons but use scientific data and calculations to render graphical depictions of real-world phenomena as accurately as possible. This practice holds true whether the animation is a simple comparison of historic earthquake magnitudes or a complex simulation cycling through thousands of high-resolution data grids to render tsunami waves propagating across an entire ocean basin. PTWC's animations fall into two broad categories. The first group illustrates concepts about seismology and how it is critical to tsunami warning operations, such as those about earthquake magnitudes, how earthquakes are located, where and how often earthquakes occur, and fault rupture length. The second group uses the PTWC-developed tsunami forecast model, RIFT (Wang et al., 2012), to show how various historic tsunamis propagated through the world's oceans. These animations illustrate important concepts about tsunami behavior such as their speed, how they bend around and bounce off of seafloor features, how their wave heights vary from place to place and in time, and how their behavior is strongly influenced by the type of earthquake that generated them. PTWC's YouTube channel also includes an animation that simulates both seismic and tsunami phenomena together as they occurred for the 2011 Japan tsunami including actual sea-level measurements and proper timing for tsunami alert status, thus serving as a video "time line" for that event and showing the time scales involved in tsunami warning operations. Finally, PTWC's scientists can use their YouTube channel to communicate with their colleagues in the research community by supplementing their peer-reviewed papers with video "figures" (e.g., Wang et al., 2012).

In the 1964 tsunami on the west coast of North America, much of the resulting damage was caused by tsunami river bores penetrating miles inland. A HEC-RAS model is used in this study to look at the likely extent of inundation from both distant and near-field tsunamis in Redwood Creek on the north coast of California. The Redwood Creek drainage basin has been analyzed extensively for riverine flooding, levee stability and sediment transport. The unsteady flow model in HEC-RAS uses an implicit finite difference scheme to approximate solutions to the continuity and momentum equations. Two different scenarios are evaluated in this analysis: 1. tsunami propagation up a dry river channel; 2. tsunami propagation up a partially full river channel. Scenario 1 provides the baseline for propagation behavior without river flow influence. Scenario 2 uses the HEC-RAS model to determine steady state conditions in the channel for different flow rates to establish initial boundary conditions. The tsunami magnitude and flow conditions are altered to determine the effect on tsunami surge propagation. This is achieved by altering the downstream boundary conditions to simulate the influence of a tsunami surge propagation event. A sensitivity analysis is conducted on the model parameters. The study will assist in tsunami hazard modeling and mitigation in areas where tsunami surge propagation is a concern to communities located along rivers.

This talk describes Tweb, a web-based tsunami forecast application that is under development at the NOAA Center for Tsunami Research for use by domestic and international partners. While the Tweb tool will centralize forecast technology at a single data center, it will also build on existing distributed tools that allow for localized tsunami inundation product generation. Tweb will be an aggregator for these distributed generated tsunami products and will allow a central access point for tsunami event forecast tools and products. This talk describes the NOAA tsunami forecast methodology on which design of the Tweb application is based, the technologies, system architecture, challenges and implementation details of the application. We also discuss the use of Tweb as a model testbed, the distributed forecast tools and their integration into Tweb.

Since that time, significant events such as the 2009 Samoa and 2011 Tohoku tsunamis have affected the U.S. and reinforced the importance of considering all of the evidence when conducting an assessment. In addition, there has been progress in tsunami research that reduces some of the earlier uncertainties. In 2011, the National Academies released their assessment of the U.S. Tsunami Program recommending that NOAA and its NTHMP partners, in collaboration with researchers in social and physical sciences, should complete an initial national assessment of tsunami risk and should institute a periodic assessment of the sources of tsunamis that threaten the United States. Therefore, the NTHMP is updating the national tsunami hazard assessment. Although the second assessment will not be a national probabilistic tsunami hazard assessment, areas where there is progress in this methodology will be presented. As a result, a national tsunami vulnerability and risk assessment is not possible at this time, but examples of ongoing work will be presented. This paper looks at the data sources in the first report, including an examination of the NGDC historical tsunami database that resulted in a qualitative assessment based on the distribution of runup heights and the frequency of tsunami runups. Although tsunami deaths are a measure of risk rather than hazard, the known tsunami deaths were compared with the qualitative assessments based on frequency and amplitude. The 2009 American Samoa tsunami resulted in a change for the U.S. Pacific island territories qualitative tsunami hazard assessment from "Moderate" to "High". The NGDC tsunami database contains reported tsunamis and is therefore limited to written records existing for an area. Some of the uncertainty in the completeness of the written record has been reduced by investigating the history of tide gauges in the different regions. The first tsunami hazard assessment also used the USGS National Seismic Hazard Map (NSHM) databases to partially extend the time interval. These databases are primarily meant to assess earthquakes affecting U.S. possessions and do not include all possible seismogenic tsunami sources in the Pacific and Atlantic Basins. However, the databases make it possible to estimate the rate of occurrence of larger magnitude earthquakes that could generate a tsunami. The USGS NSHM databases are based on tectonic models, and paleoseismic and paleotsunami data. These databases are periodically updated with new research. Inclusion of updated information can reduce uncertainties in tsunami sources such as the Cascadia subduction zone and others.

Currently, NGDC archives and processes high-resolution data recorded by the Deep-ocean Assessment and Reporting of Tsunami (DART (super R) ) network, the coastal-tide-gauge network from the National Ocean Service (NOS) as well as tide-gauge data recorded by all gauges in the two National Weather Service (NWS) Tsunami Warning Centers' (TWCs) regional networks. The challenge in processing these data is that the observations from the deep-ocean, Pacific Islands, Alaska region, and United States West and East Coasts display commonalities, but, at the same time, differ significantly, especially when extreme events are considered. The focus of this work is on how time integration of raw observations (10-seconds to 1-minute) could mask extreme water levels. Analysis of the statistical and spectral characteristics obtained from records with different time step of integration will be presented. Results show the need to precisely calibrate the despiking procedure against raw data due to the significant differences in the variability of deep-ocean and coastal tide-gauge observations. It is shown that special attention should be drawn to the very strong water level declines associated with the passage of the North Atlantic cyclones. Strong changes for the deep ocean and for the West Coast have implications for data quality but these same features are typical for the East Coast regime.

Presently, alert zones are initially based on travel time for earthquakes greater than magnitude 7.8 with all areas less than three hours away from the source being put into a tsunami warning. The impact of this change is to reduce the length of coastline which is immediately put it into a warning status. Tsunami Warning Centers often delineate initial tsunami alert zones based on pre-set criteria dependent on earthquake magnitude, location, depth, and tsunami travel time. In many cases, this approach can lead to over-warning. Over the last several years, the West Coast/Alaska Tsunami Warning Center (WCATWC) has attempted to refine the amount of coastline immediately placed in a warning status based on maximum expected threat instead of travel time. Tsunami forecast models used to predict impacts during events (for example, Alaska Tsunami Forecast Model (ATFM), Short-term Inundation Forecasting for Tsunamis (SIFT), and Rapid Inundation Forecasting of Tsunamis (RIFT)) can also be used a-priori to delineate zones at-risk for specified source zones. forecast models have proven reasonably accurate during recent events. For the Cascadia Subduction zone, several rupture scenarios ranging from magnitude 7.9 to 9.2, were computed. Forecasted wave heights at various points are then used to set the initial Warning/Watch/Advisory regions. This procedure is more efficient than a blanket warning--or a refined warning based on travel times--as appropriate threat levels are assigned based on expected impact. For example, after a magnitude 8.7 earthquake in the southern Cascadia Subduction zone, southern and most of central California can be left out of the warning zone and placed in an advisory, as none of this region contains expected impacts in the warning threshold (tsunami amplitude over 1 m). Under previous criteria, these zones would have been placed in a warning. Several examples are shown which help refine criteria used by the Tsunami Warning Center during hypothetical Cascadia events.

Archive responsibilities include the NOAA Global Historical Tsunami event and runup database, damage photos, as well as other related hazards data. Beginning in 2008, NGDC was given the responsibility of archiving, processing and distributing all tsunami and hazards-related water level data collected from NOAA observational networks in a coordinated and consistent manner. These data include the Deep-ocean Assessment and Reporting of Tsunami (DART (super R) ) data provided by the National Data Buoy Center (NDBC), coastal-tide-gauge data from the National Ocean Service (NOS) network and tide-gauge data from the two National Weather Service (NWS) Tsunami Warning Centers (TWCs) regional networks. Taken together, this integrated archive supports tsunami forecast, warning, research, mitigation and education efforts of NOAA and the Nation. Due to the variety of the water level data, the automatic ingest system was redesigned, along with upgrading the inventory, archive and delivery capabilities based on modern digital data archiving practices. The data processing system was also upgraded and redesigned focusing on data quality assessment in an operational manner. This poster focuses on data availability highlighting the automation of all steps of data ingest, archive, processing and distribution. Examples are given from recent events such as the October 2012 hurricane Sandy, the Feb 06, 2013 Solomon Islands tsunami, and the June 13, 2013 meteotsunami along the U.S. East Coast.

The low land level and high population density of China's coastal areas place it at high risk for tsunami hazards. Recent research (Komatsubara and Fujiwara, 2007) highlighted concerns of a magnitude 9.0 earthquake on the Nankai trench, which may affect China's coasts not only in South China Sea, but also in the East Sea and Yellow Sea. Here we present our work in progress towards developing a global tsunami propagation database that can be used for hazard assessments by many countries. The propagation scenarios are computed by using NOAA's MOST numerical model. Each scenario represents a typical Mw 7.5 earthquake with predefined earthquake parameters (Gica et al., 2008). The model grid was interpolated from ETOPO1 at 4 arc-min resolution, covering -80 degrees to 72 degrees N and 0 to 360 degrees E. We use this database for preliminary tsunami hazard assessment along China's coastlines.

An affirmative answer is suggested by tiered evidence for overwash 120 km south of the Puerto Rico Trench. The evidence comes from Anegada, British Virgin Islands, 200 km east-northeast of San Juan, Puerto Rico. PREVIOUS FINDINGS* suggested that a medieval overwash event had greater geologic effects at Anegada than did a Lisbon(?) event, and that both events outrank recent storms. The medieval overwash, in AD 1200-1450, dislodged brain corals from a reef, moved them as much as 500 m across a shallow subtidal flat, and scattered them as solitary boulders as much as 1000 m inland. Gentler overwash in 1650-1800, called Lisbon(?) because it may represent the 1755 tsunami, laid down a sheet of sand and island-derived shells as much as 1500 m from the north shore. A recent hurricane of category 4 left no durable geologic record other than sandy fans within 40 m of the south shore. NEW FINDINGS reinforce the ranking medieval > Lisbon(?) > storm: (1) The medieval event washed ashore marine shells that the Lisbon(?) event did not. An articulated marine bivalve (Codakia orbicularis), probably deposited live, is part of an overwash fan 400 m inland from Windlass Bight. The shell dates to the same time window as the medieval coral boulders. Additional articulated Codakia shells and a conch shell adjoin the buried base of one of these coral boulders 1500 m south of the fringing reef from which the coral was probably derived. (2) Lisbon(?) overwash used breaches that the medieval event had cut through beach ridges of the north shore. The re-use is marked by sand: on the muddy floor of a partly filled breach, on an organic soil in another such breach, and on a pre-existing fan south of an area of beach-ridge dissection. The buried organic soil, inset into a old breach, is 500 m inland from an area, near Cow Wreck High Point, where young beach ridges may have been breached for the first time during the Lisbon(?) event. (3) A storm berm of coral rubble lies seaward of a field of coral boulders that marks the medieval overwash. The berm rises as much as 3 m above fair-weather high tides along Anegada's north shore at Soldier Wash, a sand-free stretch of coast 100 m from the fringing reef. The berm consists of imbricated, well-rounded fragments 15-30 cm in diameter on average. This rubble differs in preservation, size, and distribution from the brain-coral heads 1 m in diameter that the medieval overwash scattered hundreds of meters inland from Soldier Wash.

Sources of DEM uncertainty include: uncertainty of source data, gridding interpolation to fill data gaps, and morphologic change after data collection. These uncertainties are propagated into modeling results such that the modeling of coastal inundation cannot be more accurate than the source DEMs they rely upon. We describe some of the major challenges in building coastal DEMs--those that integrate bathymetry and topography at the coast--and how to recognize errors and minimize model uncertainties. We also discuss procedures for building DEMs, and the efforts of NOAA and USGS to develop high-resolution DEMs of coastal areas impacted by Hurricane Sandy in October 2012.

In this context, use of monitored and predictive information on the warm season floods (at point-to-regional scales) has been identified as lead-information for a new 10-year long controlled flooding experiment (termed the High-Flow Experiment Protocol) intended to determine management options for rebuilding and maintaining sandbars in Grand Canyon; an adaptive strategy that can potentially facilitate improved planning and dam operations. In this work, we focus on a key concern identified by the GCDAMP, related to the timing and volume of tributary sand input from the Paria and Little Colorado Rivers (located 26 and 124 km below the dam, respectively) into the Colorado River in Grand Canyon National Park. Episodic and intraseasonal variations (with links to equatorial and sub-tropical Pacific sea surface temperature variability) in the southwest hydroclimatology are investigated to understand the magnitude, timing and spatial scales of warm season floods from this relatively small, but prolific sand producing drainage of the semi-arid Colorado Plateau. The coupled variations of the flood-driven sediment input (magnitude and timing) from these two drainages into the Colorado River are also investigated. The physical processes, including diagnosis of storms and moisture sources, are mapped alongside the planning and decision processes for the ongoing experimental flood releases from the Glen Canyon Dam which are aimed at achieving restoration and maintenance of sandbars and instream ecology. The GCDAMP represents one of the most visible and widely recognized adaptive management efforts in the world to manage resources under growing environmental uncertainty as climate change and global warming continues.

Over the past 500 years, more than 75 tsunamis have been documented in the region by the NOAA National Geophysical Data Center. Just since 1842, 3446 lives have been lost to tsunamis; this is more than in the Northeastern Pacific for the same time period. With a population of almost 160 million, over 40 million visitors a year and a heavy concentration of residents, tourists, businesses and critical infrastructure along its shores (especially in the northern and eastern Caribbean), the risk to lives and livelihoods is greater than ever before. The only way to survive a tsunami is to get out of harm's way before the waves strike. In the Caribbean given the relatively short distances from faults, potential submarine landslides and volcanoes to some of the coastlines, the tsunamis are likely to be short fused, so it is imperative that tsunami warnings be issued extremely quickly and people be educated on how to recognize and respond. Nevertheless, given that tsunamis occur infrequently as compared with hurricanes, it is a challenge for them to receive the priority they require in order to save lives when the next one strikes the region. Close cooperation among countries and territories is required for warning, but also for education and public awareness. Geographical vicinity and spoken languages need to be factored in when developing tsunami preparedness in the Caribbean, to make sure citizens receive a clear, reliable and sound science based message about the hazard and the risk. In 2006, in the wake of the Indian Ocean tsunami and after advocating without success for a Caribbean Tsunami Warning System since the mid 90's, the Intergovernmental Oceanographic Commission of UNESCO established the Intergovernmental Coordination Group for the Tsunami and other Coastal Hazards Warning System for the Caribbean and Adjacent Regions (CARIBE EWS). Its purpose is to advance an end to end tsunami warning system that serves regionally and delivers locally, saving lives and livelihoods, not only from tsunamis, but all coastal hazards. Through this and other platforms, physical and social scientists, emergency managers and elected officials have been working together via different mechanisms. Community based recognition programs, like the TsunamiReadyTM Program, regional tsunami exercises, sub-regional public education activities such as the Tsunami Smart campaigns, internet technologies, social media, meetings and conferences, identification of local and national champions, capitalization of news breaking tsunamis and earthquakes, economic resources for equipment and training have all been key to developing a tsunami safer Caribbean. Given these efforts, according to a 2013 survey, 93% of the countries covered by CARIBE EWS have tsunami response protocols in place, although much more work is required. In 2010 the US National Weather Service established the Caribbean Tsunami Warning Program as the first step towards a Caribbean Tsunami Warning Center in the region. In 2013 the Caribbean Tsunami Information Center was established in Barbados.

When NGS decided to replace the US national vertical datum, the Gravity for the Redefinition of the American Vertical Datum (GRAV-D) project added a new dimension to the NGS gravity program. Airborne gravity collection would complement existing satellite and surface gravity data to allow the creation of a gravimetric geoid sufficiently accurate to form the basis of the new reference surface. To provide absolute gravity ties for the airborne surveys, initially new FG5 absolute measurements were made at existing absolute stations and relative measurements were used to transfer those measurements to excenters near the absolute mark and to the aircraft sensor height at the parking space. In 2011, NGS obtained a field-capable A10 absolute gravimeter from Micro-g LaCoste which became the basis of the support of the airborne surveys. Now A10 measurements are made at the aircraft location and transferred to sensor height. Absolute and relative gravity play other roles in GRAV-D. Comparison of surface data with new airborne collection will highlight surface surveys with bias or tilt errors and can provide enough information to repair or discard the data. We expect that areas of problem surface data may be re-measured. The GRAV-D project also plans to monitor the geoid in regions of rapid change and update the vertical datum when appropriate. Geoid change can result from glacial isostatic adjustment (GIA), tectonic change, and the massive drawdown of large scale aquifers. The NGS plan for monitoring these changes over time is still in its preliminary stages and is expected to rely primarily on the GRACE and GRACE Follow On satellite data in conjunction with models of GIA and tectonic change. We expect to make absolute measurements in areas of rapid change in order to verify model predictions. With the opportunities presented by rapid, highly accurate absolute gravimetry, we expect that GRAV-D may be affected in a number of ways. 1) Areas requiring re-measurement as a result of poor quality data or temporal change could be measured with such a new meter. With a meter capable of field measurement with observation times that are very short, surveys previously conducted only with the relative meters could be performed with the absolute meter with no loss of time and a significant increase in accuracy. 2) Regions of rapid change due to hydrological change associated with aquifers could be measured and re-measured rather quickly. Such accuracy may provide more accurate snapshots of the aquifers over time. 3) NGS conducts absolute gravity comparisons at its Table Mountain facility for validating the performance of absolute meters through their co-located operation at gravity piers. An increase in accuracy of an order of magnitude may change the entire nature of absolute meter performance evaluation.

At seasonal and intra-seasonal time scales, polar motions are dominated by angular momentum fluctuations due to mass redistributions and relative motions in the atmosphere, oceans, and continental water, snow and ice. In this study, we compare the geophysical excitations derived from various global atmospheric, oceanic and hydrological models (NCEP, ECCO, ERA40, ERAinterim and ECMWF operational products), and construct two model sets LDC1 and LDC2 by combining the above models with a least difference method, which selects FFT coefficients of the above data series closest to those of the geodetic excitation at each frequency to build a new series. Comparisons between the geodetic excitation (derived from the polar motion series IERS EOP 08 C04) and the geophysical excitations (based on those meteorological models) imply that the atmospheric models are the most reliable while the hydrological ones suffer from significant uncertainties; that the ERAinterim is, in general, the best model set among the original ones, but the combined models LDC1 and LDC2 are much better than ERAinterim; and that applying the frequency-dependent transfer functions to LDC1 and LDC2 improves their agreements with the geodetic excitation. Thus, we conclude that the combined models LDC1 and LDC2 are reliable, and the complex and frequency-dependent Love numbers and polar motion excitation transfer functions are well modeled.

By 2020, NGS intends that all orthometric heights in the USA will be determined in the field by using a reliable national gravimetric geoid model to transform from geodetic heights obtained from GPS. Towards this end, the newly-collected airborne-gravimety is repeatedly evaluated by using it to support experimental gravitational models and gravimetric geoids, and then comparing these against independent data sets, such as 'satgrav' models (GRACE/GOCE), GPS/Leveling, astronomical vertical defections, and others. Here we show some results from these tests for GRAV-D airborne gravimetry collected over 2012/2013.

These still readings are used to account for instrument drift and to tie the measurement to an absolute gravity mark. The method used to collect still readings varies from one group or operator to another in both the length of time the gravimeter is left to settle and in whether the raw gravity value is recomputed or not. Several long-duration, stationary data sets were collected with NGS's TAGS meter, S-137. This data will be used in conjunction with the routinely collected still readings to investigate the effects of the variations in method. Additionally the routinely collected still readings will be used to examine the long term drift of both of NGS's TAGS systems, S-137 & S-161.

The better space-time data coverage and overall data precision provided by the Oersted and CHAMP satellites recently made it possible to model the secular acceleration on the global scale. Unlike measurements at isolated observatories, secular acceleration spherical harmonic models can be downward continued to the core-mantle boundary, thus providing new information on rapid core dynamics. We calculated secular acceleration models from CHAMP data every 30 days from 2002 to 2009.5 on a three-year sliding window. We found that the secular acceleration underwent two large "pulses" at the core-mantle boundary, one centered in 2006 (and previously pointed out by Chulliat et al., GRL, 2010) and the other centered in 2009. These two pulses are separated by a geomagnetic jerk near 2007, and delimited by two other jerks near 2003 and 2010.5. Their spatial structures at the core-mantle boundary are highly anti-correlated and suggest the existence of a stationary magnetohydrodynamic wave at the core surface, of period 5 to 6 years, in the low-latitude Atlantic sector. Possible interpretations of this wave in terms of core processes will be discussed, as well as relationships with other rapid core field variations observed in geomagnetic data.

Aerogravity from the Gravity for the Redefinition of the American Vertical Datum (GRAV-D) Project was first evaluated with respect to satellite gravity field models developed from both GRACE and GOCE data to establish long wavelength consistency and remove biases in individual survey lines. In turn, the airborne and satellite gravity were then combined to evaluate surface gravity data from around 1400 separate surveys over the conterminous United States (CONUS). These surveys can span anywhere from 10's to 100's of kilometers and comprise the surface gravity database held by the U.S. National Geodetic Survey. These surface data have been used as-is in the development of previous gravimetric geoid models. With the availability of aerogravity, these surveys were examined to detect and mitigate potential biases that can create artifacts in geoid height models. About 5% of these surveys exhibit significant biases of 3-5 mGals, which equate to 10-20 cm errors in subsequent geoid height models. Given the requirement for cm-level accuracy in a future vertical datum based on geoid height models, these errors must be addressed. GSVS 11 demonstrated that it is possible to combine satellite, airborne and surface gravity to achieve cm-level accuracy over a limited locale. This study demonstrates that this can also be achieved over more regional scales. While not all of the CONUS has yet been flown by the GRAV-D Project, significant portions have been flown and those regions have been evaluated here. In the GSVS 11 study, external metrics were collected simultaneously to permit evaluation of the overall error. Such data is generally not available on a national basis, but comparisons are made with the GSVS 11 data, tidal benchmarks in combination with ocean topography models, and astrogeodetic deflection of the vertical data.

An estimated 60,000 m (super 3) of sand and fine gravel were released to a downstream receiving reach that extends approximately 20 river km to Chesapeake Bay. The downstream reach is comprised of a variety of fluvial environments ranging from a comparatively steep, confined valley in lightly developed parkland in the Piedmont section to low gradient, meandering, and tidally-influenced alluvial bottoms bordered by urban development in the Coastal Plain. Less than a kilometer downstream of the Simkins dam removal site is another impoundment that was mostly filled with unconsolidated sediments before the Simkins dam was deconstructed. Bloede Dam is also being considered for removal and partial release of impounded sediment. We are evaluating the physical and biological responses of the lower Patapsco River to these two dam removals and sediment releases by comparing post-removal data with baseline data collected in 2009 and 2010. To investigate the magnitudes and rates of morphologic change in the former impoundments and the downstream receiving reach, we resurvey nearly 30 monumented cross-sections for topography, grain size distribution, and facies maps. We also resurvey detailed digital elevation models in the two impoundments and in three discrete areas of the downstream reach that cover about 2 river kilometers. Nearly 100 repeat photo stations provide qualitative morphologic information in river reaches where we are not collecting quantitative data or they otherwise supplement our physical data. The morphologic data are complemented by continuous suspended-sediment discharge and flow data at three sites: above the project reach, immediately below the Simkins dam removal site, and five kilometers downstream of Bloede Dam. To investigate biological responses to sediment release and increased aquatic connectivity, we are conducting repeat surveys of diadromous and resident fish as well as benthic macroinvertebrates. Here we report the results of nearly three years of physical and biological data collection since the Simkins Dam removal. Our physical monitoring results largely comport with pre-removal modeling estimates and earlier data from a Northeast U.S. dam removal site with many geomorphic similarities. Incision and evacuation of a substantial proportion of the sediments impounded by the Simkins dam happened rapidly during a period of relatively moderate flows, aggrading the reach immediately downstream and the upper portion of the Bloede impoundment by as much as 1.5 meters. Removal of the remaining impounded sediments, and remobilization of the initial aggradation between the Simkins Dam site and the Bloede impoundment, was substantially complete by April, 2012, accomplished by moderate discharges and episodic floods. Tropical Storm Lee, an estimated 10-year event in September, 2011, was particularly important for advancing the sediment pulse downstream of Bloede Dam where a modest, but persistent, veneer of Simkins sediment is found today as far as 7 km downstream. Though diadromous and resident fish response is neither as rapid nor as conclusive as the physical response, we find that benthic fish and macroinvertebrates respond quickly in river reaches affected by dam removal in expected ways.

Those elements exert a large influence on the stability of the West Antarctic Ice Sheet, which flows within the cradle-shaped rift system and is currently grounded well below sea level. This potentially unstable configuration is the motivation for gaining a better understanding of the ice sheet boundary conditions dictated by rift evolution and how they impact the ice flow. In this study we focus on characterizing the distribution of and transition between sedimentary basins and inferred geothermal heat flux from the flanks to the floor of the rift system. We do so through analysis of gravity data both for sources within the deep lithosphere and near surface targets in the crust. A compilation of gravity datasets over West and Central Antarctica and the analysis thereof is presented. In particular we use gravity data collected during several airborne geophysical surveys: CASERTZ (1994-1997), SOAR/WMB (1997-1998), AGASEA (2004-2005), ICEBRIDGE (2008-2011), and GIMBLE (2012-2013). New processing and data reduction methodologies are applied to the older gravity surveys to improve the high frequency signal content and to make these surveys compatible with modern works (i.e. AGASEA, ICEBRIDGE, GIMBLE). The high frequency signal provides better resolution of small-scale features within survey blocks but long-wavelength integrity is retained by registering the airborne free-air disturbance within those blocks to the gravity disturbance derived from the GOCE global satellite gravity field. This allows for consistent long wavelength interpretation across the merged surveys and provides improved gravity analysis of the deep lithosphere while retaining the capacity to study smaller scale features. A crustal model for the area is produced using the Bouguer anomaly and spectral analyses of the Bouguer anomaly and free-air disturbance. Airy isostatic corrections are applied to the Bouguer anomaly where permissible to set the foundation for the identification and discrimination of sedimentary basins and intrusive/extrusive complexes beneath the West Antarctic Ice Sheet. This analysis also provides a framework for interpreting POLENET seismic studies in the region. Successful integration of the gravity and seismic results will ultimately be necessary for understanding the thermal evolution of Marie Byrd Land and its context within the West Antarctic Rift System.

The TFZ comprises a broad right lateral transform zone made up of three major N-S striking extensional basins and three WNW-striking seismic lineaments, the dextral HFF, the Grimsey oblique rift zone (GRZ) and the Dalvik Fault System (DF). The HFF connects the North Iceland rift zone (NIRZ) with the Eyjafjardarall extensional basin (EB), the magma starved southern extension of the Kolbeinsey Ridge (KR) whereas the GRZ constitutes the offshore extension of the NIRZ with the KR. The HFF has an overall trend of N65 degrees W and can be traced 75-80 km from its eastern junction with the NIRZ, across the Skjalfandi Bay and into the Eyjafjardarall Basin. Four pull-apart basins characterize the HFF, the largest at its intersection with the EB. En echelon arrays of conjugate strike-slip faults intersect the main HFF at angles of N20 degrees -30 degrees W and N20 degrees E. Some can be traced onto land where they exhibit complicated flower patterns. Within the Skjalfandi Bay, the HFF is divided into two main branches, separated by a 70 m high N-S aligned push-up ridge and several smaller, sub-parallel WNW-trending faults. Individual fault strands have vertical displacement from 0-15 m. Large earthquakes occurred along the HFF in 1755, 1867, 1872 and 1884, the GRZ in 1884-1885 and 1910 and on the DF in 1838, 1934 and 1963. Some were destructive. A dextral transform offshore N-Iceland was initially based on diffuse earthquake epicenters and the M7, 1963 Skagafjordur earthquake. Data from the analog Iceland seismic network, established in the early 1970s, showed the TFZ microseismicity to be too diffuse to be associated with a simple oceanic transform fault. Recent seismicity within the TFZ consists of frequent earthquake swarms, lasting days or weeks with a maximum earthquake magnitude exceeding 5. Fault mechanisms reveal both normal faulting and strike-slip movements. The seismic data indicate that the HFF is flanked by bookshelf faulting both within the DF and the region between the HFF and GRZ, sometimes referred to as the Tjornes Microplate. Lateral dike propagation during the 1974-1989 Krafla rifting episode, within the NIRZ, activated adjacent transform zones, triggering the M 6.2 strike-slip Kopasker earthquake of January 13, 1976, at the junction of the NIRZ with the GRZ at the initiation and largest of the rifting events. During the propagation of the second largest rifting event, January 1978, the northward propagation along the Krafla fissure swarm was temporarily halted at the junction of the NIRZ with the HFF during which earthquakes began to propagate along the HFF, followed by continued northward propagation. Although transform motion within the TFZ is currently taken up by two parallel systems the Tjornes Microplate will merge with the North American Plate as continued northward propagation of the divergent plate boundary gradually deactivates the HFF.

Here, we follow up on first measurements of the size distribution of refractory black carbon (BC) particulate in snow that showed that BC in snow can lie in a larger size range than is typically observed in the ambient atmosphere. This observation has implications for BC light absorption in the cryosphere, as well as for the processes that govern BC removal from the atmosphere by snow and BC aging on the surface. Snow samples from the American and Canadian Mid-West and Greenland, and ice core samples from the Cascades, were stored as sampled without additional thaw/free cycles until they were analyzed in the laboratory with a single particle soot photometer/Collison nebulizer setup. Although many samples were too clean ( approximately <1 ng-BC/g-H2O) to allow measurement of high-quality BC size distributions, we were able to assess BC size in some snow samples and in presumed forest-fire emission layers captured in ice cores. Our results provide first constraints on the range and variability of the BC mass size distribution in the cryosphere, and on possible implications for the BC mass absorption cross section and role of BC in reduction of snow albedo.

Once incorporated into clouds, dust has been shown to enhance precipitation formation from in situ measurements, such as those during the CalWater field campaign (2009-2011) along the Sierra Nevada Mountains in California. Large discrepancies exists between global aerosol models that simulate the dust in the atmosphere and its impact on climate. Further, about 25% of the global dust burden originates from Asia, thus a better understanding of where and how Asian dust is transported in the atmosphere is needed, particularly with projected increases in dust emissions in mind. Asian dust is typically transported to the U.S. in the spring, but not many long-term studies of this phenomenon exist. Our results show Asian dust transport varies significantly from year-to-year and at various locations along the U.S. west coast. Observations from the National Institute for Environmental Studies (NIES) LIDAR network in Japan and the Interagency Monitoring of Protected Visual Environments (IMPROVE) network along the U.S. West Coast were analyzed in the context of HYSPLIT trajectory analyses to investigate trans-Pacific Asian dust transport from 2002-2011. Similar to previous studies, the ratio of iron to calcium from IMPROVE soil was used to estimate Asian dust concentrations at multiple sites in California, Oregon, and Washington. Asian dust estimated from IMPROVE exhibited maximum concentrations in the spring (Apr-May) on the U.S. west coast, while non-Asian dust peaked late summer (Aug-Sep). Because Asian dust is typically transported in the mid-troposphere (2-4 km), the highest concentrations of Asian dust were typically observed at higher elevation sites, such as in the Cascades and the Sierra Nevada Mountains. California experienced larger influences from Asian dust compared to Oregon or Washington, likely due to large-scale synoptic patterns and higher elevation IMPROVE sites. Dust extinction measured from 7 LIDAR sites on the east coast of Japan, located in the Asian dust outflow region, was compared to seasonal and interannual trends in IMPROVE Asian dust. The highest LIDAR-derived dust extinction coefficients were observed from 2-5 km, although distinct layers were not evident most of the years. Dust extinction peaked in the spring to early summer (Apr-Jun), consistent with the IMPROVE record and previous studies. Good agreement existed between the trends in relative amount of dust from LIDAR and IMPROVE measurements, even though they are located thousands of kilometers apart. Trajectory analyses indicate transport from the Asian outflow region to the U.S. was lowest in the summer/fall, and highest in the winter/spring. Air masses were either transported zonally across the Pacific, or traveled north and then south along the west coast in the large-scale undulating flow. This work presents a 10 year record of dust along the U.S. West Coast in an effort to study Asian dust transport to the western U.S. JF - American Geophysical Union Fall Meeting AU - Creamean, J AU - Spackman, J R AU - Anonymous Y1 - 2013/12// PY - 2013 DA - December 2013 SP - Abstract A52D EP - 03 PB - American Geophysical Union, Washington, DC VL - 2013 KW - 22:Environmental geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1660632435?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=Climatology+of+long-range+transport+of+Asian+dust+on+the+U.S.+West+Coast&rft.au=Creamean%2C+J%3BSpackman%2C+J+R%3BAnonymous&rft.aulast=Creamean&rft.aufirst=J&rft.date=2013-12-01&rft.volume=2013&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 2013 fall meeting N1 - Copyright - GeoRef, Copyright 2015, American Geosciences Institute.

As a result, the US has become the largest producer of natural gas in the world. This growth in natural gas production may result in increased leakage of methane, a potent greenhouse gas, offsetting the climate benefits of natural gas relative to other fossil fuels. Methane emissions from natural gas production are not well quantified because of the large variety of potential sources, the variability in production and operating practices, the uneven distribution of emitters, and a lack of verification of emission inventories with direct atmospheric measurements. Researchers at the NOAA Earth System Research Laboratory (ESRL) have used simple mass balance approaches to estimate emissions of CH (sub 4) from several natural gas and oil plays across the US. We will summarize the results of the available aircraft and ground-based atmospheric emissions estimates to better understand the spatial and temporal distribution of these emissions in the US.

CH (sub 4) produces a relatively high radiative forcing effect upon the Earth's climate, and its atmospheric lifetime of approximately 10 years makes it a more appealing target for the mitigation of climate change over short timescales than long-lived greenhouse gases such as carbon dioxide. However, the spatial and temporal variation of CH (sub 4) emissions are still not well understood, though in recent years a number of top-down and bottom-up studies have attempted to construct improved emission budgets. Some top-down studies may suffer from poor observational coverage in tropical regions, however, especially in the planetary boundary layer, where the atmosphere is highly sensitive to emissions. For example, although satellite observations often take a large volume of measurements in tropical regions, these retrievals are not usually sensitive to concentrations at the planet's surface. Methane emissions from Amazon region, in particular, are often poorly constrained. Since emissions form this region, coming mainly from wetland and biomass burning sources, are thought to be relatively high, additional observations in this region would greatly help to constrain the geographical distribution of the global CH (sub 4) emission budget. In order to provide such measurements, the AMAZONICA project began to take regular flask measurements of CH (sub 4) and other trace gases from aircraft over four Amazonian sites from the year 2010 onwards. We first present a forward modelling study of these observations of Amazonian methane for the year 2010 using the TOMCAT Chemical Transport Model. The model is used to attribute variations at each site to a source type and region, and also to assess the ability of our current CH (sub 4) flux estimates to reproduce these observations. Although there is mostly good agreement between the modelled and observed CH (sub 4) , we find discrepancies between the two at one site in the east of the region, indicating possible errors surrounding the surface fluxes of methane affecting this site. We also present the results of an inverse modelling study of methane emissions for the year 2010, using INVICAT, which is a new variational inverse model based upon TOMCAT. This study represents the first use of the INVICAT scheme to constrain emissions of an atmospheric trace gas. Similarly to many previous inverse model studies, this top-down study assimilates ground-based flask observations of CH (sub 4) from the NOAA ground network. However, in order to provide additional constraints of CH (sub 4) emissions in the Amazon region, flask observations taken as part of the AMAZONICA campaign are also assimilated. The results of this inversion provide improved Amazonian and global CH (sub 4) emission budgets for the year 2010.

AN - 1660631718; 2015-018649 AB - The early Pliocene warm period (dated around 4 million years ago) is an intriguing test case for Global Climate Models (GCMs) as it was the last time today's CO (sub 2) levels are seen in the paleorecord. However, proxy data of the early Pliocene sea surface temperatures (SSTs) suggest that the Earth was substantially warmer at that time than today. Here, we use the GFDL's AM2.1 atmospheric GCM, being forced with a Pliocene SST reconstruction, to study the roles of fast physical processes in sustaining such warming and consider the implications for the model's fitness in simulating anthropogenic global warming (AGW). At the top-of-the-atmosphere (TOA), outgoing longwave radiation (OLR) should be in approximate balance with shortwave absorption (SWABS) for the climate to remain extendedly steady (as in the Pliocene). It is found that with a global mean surface temperature increase of about 4.4K over today's conditions (control run) the Pliocene run shows an increase in both SWABS and OLR (9.7 and 6.1 W/m2, respectively). The 3.6 W/m (super 2) imbalance introduced may indicate a difficulty in the model's ability to simulate the Pliocene steady conditions, most likely due to the model's cloud parameterizations. The Pliocene warming had many different climatic impacts than AGW is predicted to including redistribution of cloud cover and precipitation patterns, with a strong shift in both from ocean to land, as well as opposing changes in oceanic and atmospheric meridional heat transport.

Five of the research flights utilizing the NOAA WP-3D aircraft focused on areas of intensive oil and natural gas production from various shale plays. These areas included the Haynesville shale in eastern Texas and western Louisiana, the Fayetteville shale in northern Arkansas, and the Marcellus shale in western Pennsylvania. According to the U.S. Energy Information Administration's (EIA) Annual Energy Outlook 2013 report, (1) the Haynesville, Fayetteville, and Marcellus shale collectively account for approximately 75% of the dry shale gas produced in the U.S., and (2) shale gas is expected to provide the largest source of growth in the U.S. natural gas supply over the next few decades. Depending on the particular shale formation, raw natural gas can contain significant amounts of non-methane hydrocarbons in the form of natural gas liquids (e.g., ethane, propane, butanes) and natural gas condensate (e.g., pentanes, cycloalkanes, and aromatics). Trace gases including methane, aromatics, formaldehyde, other oxygenated VOCs, carbon monoxide, and nitrogen oxides were measured by multiple instruments aboard the NOAA WP-3D research aircraft. Up to 72 whole air samples (WAS) were collected in flight and analyzed in the field post-flight for a variety of volatile organic compounds (VOCs). Whole air samples provide a detailed chemical snapshot that can be combined with higher time-resolved measurements in order to provide a more comprehensive chemical analysis. In this presentation, we will compare the emissions composition of the Haynesville, Fayetteville, and Marcellus shale plays to investigate the relative importance of primary VOC emissions on the formation of secondary pollutants such as ozone, oxygenated VOCs, and secondary organic aerosol.

Properties of cirrus ice nuclei (IN) have not been well constrained due to a lack of systematic measurements in the upper troposphere. In a recent study of several northern hemisphere regions we report the size and composition of sublimated cirrus particles sampled from a high altitude research aircraft using both in situ and offline techniques. Mineral dust was consistently the most abundant particle type in cirrus residuals, suggesting that heterogeneous nucleation was a dominant cirrus formation mechanism in these study regions. Other proposed heterogeneous IN, including biomass burning particles, elemental carbon, and biological material, were not abundant in cirrus residuals. Clear sky measurements show that mineral dust was ubiquitous in the background upper troposphere at levels from approximately 1 to 100's per liter and typically accounted for 5-40% of the particulate mass. Principal sources of upper tropospheric mineral dust include strong biomass burning events and deep convection, although some evidence suggests that dust aerosol is preferentially scavenged in convective systems. During transport mineral dust accumulates secondary sulfate, nitrate, and organic material that can reduce IN efficiency. Most upper tropospheric dust particles contain secondary material, and coating type and thickness depend on coemissions and the vertical transport mechanism.

Dust concentrations have been observed at Alert (82.39 degrees N, 62.3 degrees W), Canada since 1980. In this study we simulate transport of natural and pollution dust aerosols to the Arctic in the GFDL global chemical transport model, and compare model dust concentrations to the observations. The model predicts peak concentrations in spring caused by dust entrainment in Asian and Saharan deserts. Dust concentrations are low in winter and have a significant contribution from anthropogenic pollution sources, permitting the formation of low-level, optically opaque mixed-phase clouds. Based on the observational and modeling results, we suggest that anthropogenic pollution can cause substantial perturbations to Arctic IFN and clouds in winter.

Because methane is more energy-rich than coal per kg of CO (sub 2) emitted into the atmosphere, it represents an attractive alternative to coal for electricity generation, provided that the fugitive emissions of methane are kept under control. A key step in assessing these emissions in a given region is partitioning the observed methane emissions between natural gas fugitive emissions and other sources of methane, such as from landfills or agricultural activities. One effective method for assessing the contribution of these different sources is stable isotope analysis, using the delta (super 13) CH (sub 4) signature to distinguish between natural gas and landfills or ruminants. We present measurements of mobile field delta (super 13) CH (sub 4) using a spectroscopic stable isotope analyzer based on cavity ringdown spectroscopy, in three intense natural gas producing regions of the United States: the Denver-Julesburg basin in Colorado, the Uintah basin in Utah, and the Barnett Shale in Texas. Mobile isotope measurements of individual sources and in the nocturnal boundary layer have been combined to establish the fraction of the observed methane emissions that can be attributed to natural gas activities. The fraction of total methane emissions in the Denver-Julesburg basin attributed to natural gas emissions is 78 +/- 13%. In the Uinta basin, which has no other significant sources of methane, the fraction is 96% +/- 15%. In addition, results from the Barnett shale are presented, which includes a major urban center (Dallas / Ft. Worth). Methane emissions in this region are spatially highly heterogeneous. Spatially-resolved isotope and concentration measurements are interpreted using a simple emissions model to arrive at an overall isotope ratio for the region.

The three regions are (1) the Haynesville and (2) Fayetteville shale plays, located in eastern Texas/western Louisiana and western Arkansas, respectively, and (3) a part of the Marcellus shale play located in northeastern Pennsylvania. From these measurements, we derive methane emission rate estimates by calculating the methane advection flux in the planetary boundary layer downwind of the region, minus the methane flux upwind of the region. By attributing the methane emissions to natural gas extraction, we place an upper limit on the natural gas emissions from the region. We then compare this emission to the total volume of natural gas extracted from the region to derive an upper limit on the natural gas leak rate from extraction operations.

In this presentation we will focus on the multiple species analysis in discrete air samples collected with the NOAA Mobile Laboratory (ML) and the light aircraft in the Uinta Basin (Utah), Denver Julesburg Basin (Colorado) and Barnett Shale (Texas). Hydrocarbon ratios in samples collected with the ML downwind of specific sources show significantly more variability than the aircraft samples. These surface samples provide some useful information about the composition of various sources in each region. Ratios of the non-methane hydrocarbons on the ground and higher in the boundary layer show some differences between the plays, which could be explained by the different composition of the raw gas being produced or by different mixes of sources contributions. Understanding the speciation of atmospheric emissions is critical to identify emission vectors and to assess their potential air quality and climate impacts. Our measurement results will be compared with data from other studies, including emission inventories.

The region is tectonically complex with back-arc spreading centers, rift zones, and volcanic centers, all of which potentially host active venting and/or active volcanism. To date, 400 km of the three back-arc spreading centers in the NE Lau basin (FRSC, Fonualei Rift and Spreading Center; MTJ, Mangatolu Triple Junction; and NELSC, Northeastern Lau Spreading Center) plus several volcanic centers have been systematically surveyed for hydrothermal plumes using towed CTD or MAPR arrays that include both optical backscatter and oxidation-reduction potential (ORP) sensors. The FRSC, where spreading rates range from 47 mm/a in the south to 85 mm/a in the north, has 5 active sites (plume depths ranging from 1300-2200 m) distributed one every approximately 40 km over its 200 km length. There is evidence for 4 active sites (plume depths range from 1950-2380 m) along the 150 km combined length of the MTJ segments, however plumes were optically weak (dNTU < 0.02) and except for one location along the northeastern limb, no ORP anomalies were detected. Plumes were observed off-axis to the MTJ at a bathymetric high adjacent to the northeastern limb (1700 m) as well as over the summit of a cratered volcanic edifice east of the central junction (1200-1300 m). The southern segment of the NELSC was the site of an active eruption in 2008 which injected event plumes throughout the water column (900-1600 m depth range) in addition to the chronic plume from the Maka massive sulfide vent site (1500 m). There is evidence for at least two additional active areas along the northern segments of the NELSC (1800-1900 m). Several volcanoes in the region are hydrothermally active ranging from the northernmost volcano on the Tonga arc (Niua) with plumes centered at 600-1000 m, to the series of North Mata volcanoes where hydrothermal plumes disperse into the water column at depths ranging from 2000 to 2600 m, and the especially intense plumes over West Mata (1050 - 1200 m) while it was observed actively erupting in 2008 and 2009. The regional picture is not one of a clear "smoking-gun" source for the 1750 m helium plume, but one of widespread hydrothermal and volcanic activity injecting hydrothermal products to the ocean over a broad depth range.

A study of the Sacramento basin gas fields (Poreda et al, 1986) showed that the highest high R/Ra values (1.97 to 2.75) were found in the gas fields associated with buried Plio-Pleistocene igneous intrusives occur. Other fields in the area typically have R/Ra values close to or less than 1.0. Our results are consistent with previous work in that the Los Angeles basin has igneous intrusions in the deep part of the sequence that represents early-mid Miocene extension. Examples of this are the fields sampled along the Newport-Inglewood fault including the Inglewood field and the Long Beach field that have R/Ra values between 1.88 and 3.07 . On the other hand the more central and northern part of the LA basin illustrated by the Santa Fe Springs and Sawtelle fields do not have a strong mantle signature (R/Ra between 0.18 and 0 .32). In the San Joaquin basin, R/Ra values are consistently low (R/Ra 0.015 to 0.64; average 0.21) presumably due to the thick sedimentary section and absence of an igneous connection to the mantle in the lower part of the basin.

Tofua segment of the Tonga Arc AN - 1656036734; 2015-012966 AB - Volcanism along the northernmost Tofua Arc is enigmatic because edifices of the arc's volcanic front are mostly, magmatically relatively anemic, despite the very high convergence rate of the Pacific Plate with this section of Tonga Arc. However, just westward of the arc front, in terrain generally thought of as part of the adjacent NE Lau Backarc Basin, lie a series of very active volcanoes and volcanic features, including the large submarine caldera Niuatahi (aka volcano "O"), a large composite dacite lava flow terrain not obviously associated with any particular volcanic edifice, and the Mata volcano group, a series of 9 small elongate volcanoes in an extensional basin at the extreme NE corner of the Lau Basin. These three volcanic terrains do not sit on arc-perpendicular cross chains. Collectively, these volcanic features appear to be receiving a large proportion of the magma flux from the sub-Tonga/Lau mantle wedge, in effect "stealing" this magma flux from the arc front. A second occurrence of such magma "capture" from the arc front occurs in an area just to the south, on southernmost portion of the Fonualei Spreading Center. Erupted compositions at these "magmatically greedy" volcanoes are consistent with high slab-derived fluid input into the wedge (particularly trace element abundances and volatile contents, e.g., see Lupton abstract this session). It is unclear how long-lived a feature this is, but the very presence of such hyperactive and areally-dispersed volcanism behind the arc front implies these volcanoes are not in fact part of any focused spreading/rifting in the Lau Backarc Basin, and should be thought of as "reararc volcanoes". Possible tectonic factors contributing to this unusually productive reararc environment are the high rate of convergence, the cold slab, the highly disorganized extension in the adjacent backarc, and the tear in the subducting plate just north of the Tofua Arc.

Due to the inaccessibility of much of the Arctic region in situ aircraft measurements are well suited to providing a high spatial resolution map of a changing Arctic. We present here measurements of methane emissions from thermokarst lakes and melting permafrost in the North Slope region of Alaska. These measurements were acquired during the summer 2013 mission of the Flux Observations of Carbon from an Airborne Laboratory (FOCAL) instrument suite using the Aurora Flight Sciences' Centaur aircraft. The FOCAL payload combines the Anderson Group's (Harvard University) Carbon spectrometers for measuring the concentrations of methane, carbon dioxide, nitrous oxide, and water vapor and the carbon isotopologues of methane and carbon dioxide with the NOAA Atmospheric Turbulence and Diffusion Division (ATDD) Best Air Turbulence (BAT) probe for measuring the turbulent winds from a moving aircraft. Together these allow for the measurement of trace gas fluxes. The measurements were obtained by flying low ( approximately 10 m altitude) over the North Slope.

This can be done using Volcanic Ash Transport and Dispersion models (VATD). These models require Eruption Source Parameters (ESP) such as the mass eruption rate (MER), as input. MER can be estimated from volumetric flux assuming gravity current behavior of the atmospheric intrusion. We used a gravity current model for the umbrella cloud and downwind plume in which the predominantly horizontal spreading through the atmosphere is driven by buoyancy forces and wind drag. Ash is advected by these atmospheric motions and settles out relatively slowly under the action of gravity. Given the importance of knowing ESP for VATD, we explored the use of the gravity current model applied to satellite imagery, using the geometric characteristics of ash clouds. To test the gravity current model on the use of satellite imagery, we estimated ESP from five well-studied and well-characterized historical eruptions: Mount St. Helens, 1980; Pinatubo, 1991, Redoubt, 1990; Hekla, 2000 and Eyjafjallajokull, 2010. These tests show that the methodologies yield results comparable to currently accepted methodologies of ESP estimation. We then applied the methodology to umbrella clouds produced by the eruptions of Okmok, 12 July 2008, and Sarychev Peak, 12 June 2009, and to the downwind plume produced by the eruptions of Hekla, 2000; Kliuchevsko'i, 1 October 1994; Kasatochi 7-8 August 2008 and Bezymianny, 1 September 2012; none of which had previous estimates of MER.

One such feedback involves methane emissions from wetlands. Vast stores of carbon in the Arctic may thaw over the next centuries, and it is important to understand how wetlands will evolve over time since large scale drying will likely result in smaller emissions of CH (sub 4) and more respiration of CO (sub 2) . Permafrost thaw can also produce smaller emissions if ponded soils drain. Changes in precipitation and land use in the Tropics and mid-latitudes may also lead to significant changes in emissions, shifting the balance between respiration of CH (sub 4) and CO (sub 2) . Modeling CH (sub 4) emissions from wetlands is a complicated problem since even the distribution of wetlands is subject to much uncertainty and is treated in a variety of ways in current CH (sub 4) emission models. Nutrient cycling and small-scale processes must also be represented at scales that are large enough to be interpreted at global scales. Ultimately, confidence in models that couple greenhouse gas emissions with climate models should be dependent on the ability of the emission models to reproduce the current observed spatial distribution and variability. Global network and campaign data are critical to evaluation of bottom-up emission models, and here we show results using both global and regional modeling approaches. Inverse techniques can also provide details on how simulated emissions must be adjusted in order to obtain optimal agreement with observations, and this can lead to insights into deficiencies in the models. We demonstrate this by showing results from a suite of inversions performed using different wetland models.

In support of an aircraft eddy covariance campaign beginning in 2013, a CH4 and CO2 eddy covariance flux tower was installed in a wet sedge ecosystem along the aircraft measurement transect, south of Prudhoe Bay, AK. The tower-based results indicate that this ecosystem is a strong source of CH4 to the atmosphere, with preliminary fluxes of approximately 100 mg CH4 m-2 day-1 measured in late July. Prior to installation in Alaska, the tower and aircraft flux measurement systems were also compared for one week over a salt marsh on Wallops Is, VA in June, 2013. The flux of CH4 to the atmosphere was significantly smaller than at the sedge site in Alaska, and was measured by the eddy covariance tower to be about 10 mg CH4 m-2 day-1. Results from this study will be presented, with a specific focus on the tower-based CH4 flux measurements and their correlation with soil temperature.

It's a fact that the increase of CO2 is due to human-caused emissions from land use change and fossil fuel use. Yet, an average of 54% of these human emissions was removed from the atmosphere by CO2 sinks in the ocean and the land biosphere. In the IPCC AR5 report, an update of the global carbon budget is provided, together with CH4 sources and sinks, over the last 3 decades. The first finding is the recent acceleration of fossil fuel CO2 emissions during the last decade, and the fact that sinks have increased proportionally with emissions. Future projections of the coupled climate-carbon cycle system using CMIP5 models, translated into compatible emissions for each RCP pathway radiative forcing trajectory will be presented. When the carbon cycle is coupled to simulations of climate change, the sinks weaken, causing a positive feedback on warming, but uncertainties on the magnitude of this feedback and on the role of each regions, remain very high, as shown by the large spread between models. The second finding concerns additional feedbacks, most likely of positive sign, such as CO2 and CH4 emissions from thawed permafrost and nutrient limitations on land carbon storage. These feedbacks were not included in the CMIP5 models and represent a large (but uncertain) source of extra warming for any given economic scenario of anthropogenic emissions JF - American Geophysical Union Fall Meeting AU - Ciais, P AU - Sabine, C L AU - Anonymous Y1 - 2013/12// PY - 2013 DA - December 2013 SP - Abstract U22A EP - 01 PB - American Geophysical Union, Washington, DC VL - 2013 KW - 22:Environmental geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1656034156?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=Carbon+cycle+and+climate+change%2C+a+tale+of+increasing+emissions+and+uncertain+future+sinks&rft.au=Ciais%2C+P%3BSabine%2C+C+L%3BAnonymous&rft.aulast=Ciais&rft.aufirst=P&rft.date=2013-12-01&rft.volume=2013&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 2013 fall meeting N1 - Copyright - GeoRef, Copyright 2015, American Geosciences Institute.

The eruption cloud diminished rapidly on satellite imagery suggesting it was water-vapor dominated (McGimsey et al., 2010). A multibeam survey by R/V Melville was conducted in early February 2013 over the unsurveyed main peak and to enable comparison with the available older surveys (a 2002 Ewing [EW0202] and a 2003 Thompson [TN153] surveys) of the north peak where the eruption was believed to have taken place. The comparison shows negative depth changes of up to approximately 200 m at the summit of the northern peak, coinciding with the development of a crater approximately 360 m in diameter, breached to the west. Downslope and west of the breach in the crater, a zone of positive depth changes of >50 m occurs to approximately 2000 m depth on the volcano's flank. This is interpreted to be the deposit of material from the 2010 eruption together with part of the western flank that failed during the eruption. The volume of the downslope deposit is approximately twice as large as the amount of material lost from the summit. JAMSTEC NT13-12 cruise on the R/V Natsushima with the ROV Hyper-Dolphin 3000, was conducted from June 14 to June 22, 2013. This cruise included two dives (HPD1533 and HPD1534) to observe and sample the summit crater and the western flank of South Sarigan volcano, along with SeaBat bathymetry surveys of the site. HPD1533 explored the 2010 crater to search for hydrothermal activity and to image and sample the northern crater wall (404-238 mbsl). The northern wall of the crater appears to be dominantly well-jointed andesite, with some interlayered basalt. No hydrothermal venting was observed in the crater, except weak shimmering water at the top of the crater wall. HPD1534 set out to investigate the part of the western flank with the maximum positive depth change to image and sample the seafloor and recover material from the 2010 eruption. The western flank covered during HPD1534 (1,538-1,355 mbsl) consisted of boulders strewn across a sediment-covered seafloor. The boulders may have originated from the western flank of South Sarigan, either as a result of slope failures during the 2010 eruption or from earlier events. The deposits consist of altered andesites and moderately fresh basalts, which appeared to be better represented here than in the northern wall of the crater (HPD1533). The sediments recovered range from mud to gravels and include some pumiceous lapilli. The top layer often appeared to be oxidized to an orange color, and a similar colored orange oxidation covered the boulders. Analyses of the core material and the summit samples will hopefully elucidate the relationship of the downslope deposits to the summit eruption.

Underwater explosive eruptions driven by magmatic gases were first witnessed here in 2004 and the volcano has remained persistently active ever since. During a March 2010 expedition to NW Rota-1 with the remotely operated vehicle Jason, we observed intermittent explosive activity at five distinct eruptive vents along a line 100-m long near the summit of the volcano (550-590 m depth). The continuous but variable eruptive activity produced CO2 bubble plumes that rose in the water column over the volcano and could be readily imaged by sonar because they provide excellent acoustic reflectors. This study compares the manifestations of NW Rota's eruptive activity as measured by several independent methods, including: (1) an EM122 multibeam sonar system (12 kHz) on the R/V Kilo Moana that imaged bubble plumes in the water column over the volcano, (2) hydrophone data that recorded the sounds of the variable eruptive activity, and (3) visual observations of the activity at the eruptive vents on the seafloor from Jason. Throughout the 2010 expedition numerous passes were made over the volcano's summit to image the bubble plumes with the EM122 multibeam sonar, in order to capture the variability of the plumes over time and to relate them to the eruptive output of the volcano. The mid-water sonar dataset totals >95 hours of observations over a 12-day period. Analysis of the EM122 dataset shows: (1) bubble plumes were visible in the water column on every pass over the summit, (2) separate plumes were resolvable from up to 4 of the 5 eruptive vents at times, (3) plume heights and intensities were variable with time, (4) the highest observed bubble plume rise height was 415 meters above the seafloor to within 175 m of the ocean surface, while lower amplitude wisps rose to heights <100 m from the surface, (5) most of the bubble plumes were deflected to the WSW in the prevailing current. We will compare these bubble plume results to the time-series of eruptive intensity as measured by the hydrophone recordings, with ground-truth provided by the Jason visual observations at the eruptive vents. This will show to what extent the variability of eruptive output observed on the seafloor is reflected in the plume dynamics. We will also compare ocean current data from the ship's acoustic doppler current profiling (ADCP) sonar to the distance and direction of deflection of the bubble plumes. These data will be used to test whether multibeam-sonar water-column data can be used as a proxy to determine the level of eruptive activity above submarine volcanoes that have robust CO2 output. We also plan to compare these results with independent quantitative CO2 flux estimates made from the hydrophone data.

Gradually, the Initiative was joined by numerous international projects launched in EU, Russia, the United States, Canada, Japan, and China. Throughout its duration, NEESPI served and is serving as an umbrella for more than 160 individual international research projects. Currently, the Initiative is in full swing. The total number of the ongoing NEESPI projects (as on July 2013) is 50 and has changed but slightly compared to its peak (87 in 2008). The past one and one-half years (2012-through mid-2013) were extremely productive in the NEESPI outreach. We organized five Open Science Sessions at the three major Geoscience Unions/Assembly Meetings (AGU, EGU, and JpGU) and four International NEESPI Workshops. The programs of two of these Workshops (in Irkutsk and Petrozavodsk, Russia) included Summer Schools for early career scientists. The list of publications of NEESPI scientists was still incomplete at the time of preparation of this abstract. A large suite of NEESPI articles (59) is currently at different stages of review process for the Forth Special NEESPI Issue of "Environmental Research Letters" (http://iopscience.iop.org/1748-9326/focus/NEESPI4). In the past 12 months, we continued releases of the latest findings in the NEESPI domain in regional monographs with publication of two such monographs devoted to Siberia and Dryland East Asia (Groisman and Gutman eds. 2013 and Chen et al. 2013). Keeping in mind an orderly completion of NEESPI in 2015 and a desire of the NEESPI project leaders and their numerous associates to continue studies of the Northern Eurasia role in the Earth System within the FUTURE EARTH Mega Program, we have begun development of the new set of scientific ideas for regional projects for the post-NEESPI period. The goal is to formulate these ideas (science questions) in such way that they will secure fruitful regional and global research for the next decade (as the NEESPI Science Plan did in 2004) and will use new tools that became available (such as Earth System Models, new remote sensing products and field campaigns). These ideas will be discussed at the Meeting.

If mobilized to the atmosphere, this carbon would have significant impacts on global climate, especially if emitted as CH4, a gas that is about 25 times more potent a greenhouse gas per mass than CO2 over a century timescale. Arctic temperatures have been increasing rapidly over the last several decades, with melting of ice both on sea and land, sometimes at surprisingly fast rates. Human activities in the Arctic are sure to expand as the climate moderates, and one of the challenges confronting our ability to predict the future global climate is understanding the potential evolution of trace gas budgets in the Arctic. Bottom-up estimates from flux towers and chamber studies over the past several decades imply that the Arctic is taking up more CO2 and emitting more CH4. Atmospheric network observations do not currently support long-term increases in CH4 emissions, although inter-annual variability due to year-to-year temperature changes is seen in the atmospheric data. Small changes in CO2 uptake are difficult to detect given the overwhelming dominance of the fossil fuel emissions in the CO2 budget. A commitment to long-term monitoring of greenhouse gases using both regionally representative bottom-up measurements and top-down atmospheric network observations in the Arctic is fundamental to our ability to detect early changes in carbon emissions, as well as to evaluate and test models that predict future carbon cycle climate feedbacks.

CARVE bridges critical gaps in our knowledge and understanding of Arctic ecosystems, linkages between the Arctic hydrologic and terrestrial carbon cycles, and the feedbacks from fires and thawing permafrost. We present CARVE airborne measurements of spatial and temporal patterns in atmospheric CH4 concentrations and estimated surface-atmosphere emissions for Arctic and Boreal Alaska. Continuous in situ CH (sub 4) , CO (sub 2) and CO data are supplemented by periodic whole air flask samples from which (super 13) CH (sub 4) and non-methane hydrocarbons are used to assess the relative contributions of wetlands, fossil fuel combustion, and oil and gas production to the observed CH (sub 4) signals. The CARVE project has also initiated monthly (super 14) CH (sub 4) sampling at Barrow, AK (BRW) and the CARVE Tower in Fox, AK (CRV) to evaluate seasonal changes in the fraction of old carbon being mobilized via methanogenesis.

For example, the loosely bound electrons create large dipoles that lead to long-range interactions between Rydberg atoms that are many orders of magnitude stronger than those between ground-state atoms. Strong interactions between Rydberg atoms can enable energy transport over distances many times the size of the atoms (1). On page 954 of this issue (2), Guenter et al. describe how they have nondestructively and continuously imaged resonant-energy transfer between cold 87Rb Rydberg atoms with controlled coupling to the environment. Their technique may enable the engineering of open quantum systems for quantum simulation (3), which could lend insight to the transition from classical to quantum energy transport in complex systems. The nature of this transition in a dissipative environment remains an open question and may have relevance to the efficiency of dipole-coupled energy transport in molecular systems such as photosynthetic light-harvesting complexes (4).

AN - 1539445451; 15959 AB - PURPOSE: The amendment of the Southern California National Forests Land Management Plan (LMP) to revise land use zone allocations for select inventoried roadless areas (IRAs) within the Angeles, Cleveland, Los Padres, and San Berdardino national forests is proposed. The four forests play an important regional role in maintaining large blocks of wildlife and plant habitat. They also contain areas that are the only remaining habitat for species imperiled by the loss or degradation of habitat off-forest. Revised LMPs approved in 2006 allocated lands within IRAs to various land use zones based on wilderness evaluations that were completed as part of a final EIS. This proposed LMP amendment is a result of the settlement agreement approved January 3, 2011 for California Resources Agency, et al vs. United States Department of Agriculture, and Center for Biological Diversity, et al vs. United States Department of Agriculture. Four alternative land use zone allocations for 35 IRAs, along with three alternative monitoring strategies, are considered in this final supplemental EIS. Under the No Action Alternative (Alternative 1), the current land use zones would be implemented. The proposed action (Alternative 2) would change the land use zone allocation to back country non-motorized (BCNM) on 300,000 acres, and change the land use zone allocation to recommended wilderness on 80,000 acres. The majority of the additional BCNM allocations are located in IRAs on the Los Padres and San Bernardino national forests. Additions to recommended wilderness allocations are within IRAs on the Angeles and Cleveland national forests. On the Angeles National Forest, the Fish Canyon and Salt Creek IRAs were combined to create the proposed 40,000 acre Fish Canyon recommended wilderness area. On the Cleveland National Forest, the proposed 23,000 acre Eagle Peak recommended wilderness area includes portions of the Eagle Peak, Sill Hill, and No Name IRAs, along with portions of the Cedar Creek and Upper San Diego River undeveloped areas. The 11,000-acre Barker Valley and 5,000-acre Caliente recommended wilderness areas are also proposed on the Cleveland National Forest. The preferred alternative (Alternative 2a) includes the design criteria and features of Alternative 2, but with a few modifications to the land use zones. Alternative 3 would rezone the majority of the land use zones allocated within the IRAs to recommended wilderness. With regard to monitoring protocols, the No Action Alternative (Alternative A) would not change the current monitoring requirements. The proposed action (Alternative B) would update monitoring for forest health, riparian condition, and biological resource condition. Clarified indicators would reflect current inventory methodology in several areas, and a new indicator would track unauthorized roads and trails. Alternative C would provide for more intensive inventories and surveys than the current monitoring plan or Alternative B. The preferred land use zone alternative for the Angeles, Los Padres, and San Bernardino forests is Alternative 2. The preferred land use zone alternative for the Cleveland National Forest is Alternative 2, with the exception of the Cedar Creek undeveloped area where the preferred alternative is to expand the recommended wilderness to the east as proposed in Alternative 3. The preferred monitoring alternative for all four forests is Alternative B. POSITIVE IMPACTS: The proposed action would respond to the terms of the settlement agreement. Long-term effects may be beneficial to special status plant species and wildlife habitat. NEGATIVE IMPACTS: Restrictions on future motorized access may limit access for recreation and sites of importance to Native American communities. In addition, the proposed action would generally place further restrictions on commodity development.

AN - 16397045; 15944 AB - PURPOSE: Improvements to Interstate 5 (I-5) from La Jolla Village Drive in the City of San Diego to Harbor Boulevard in the City of Oceanside, California are proposed. Located in San Diego Countys north coastal area, the 27-mile I-5 North Coast Corridor connects the cities of Oceanside, Carlsbad, Encinitas, Solana Beach, Del Mar and San Diego. The corridor is one of the most traveled highways in the nation and there have been minimal improvements to the existing facility since the original construction during the 1960's and 1970's. The draft EIS of June, 2010 assessed four build alternatives that would include one or two high-occupancy vehicle (HOV) managed lanes in each direction, auxiliary lanes where needed, and possibly one general purpose lane in each direction. A locally preferred alternative (LPA) was identified in July, 2011. The LPA is the 8+4 Buffer Alternative, also known as the I-5 Express Lanes, and would consist of two HOV/managed lanes in each direction, separated by a buffer from the existing four general purpose lanes in each direction. The HOV/managed lanes would be available for carpools, vanpools, and buses at no cost, and to single-occupant vehicles for a fee when there is sufficient capacity. Six bridges over lagoons would be redesigned with a minimum width of 194 feet. This draft supplemental EIS summarizes project design features and discusses new information obtained from additional studies conducted at the lagoons and lagoon crossings in the North Coast Corridor. New bridges are now proposed at Agua Hedionda, San Elijo, Batiquitos, and Buena Vista lagoons, with longer bridges proposed at the latter three lagoons. In addition, a number of enhancements have been developed for the project including pedestrian, bicycle, park and ride, gateway, streetscape, and park enhancements. The North Coast Bikeway would complement the Coastal Rail Trail and the El Camino Bicycle Corridor, as well as the California Coastal Trail. The cost for the LPA is estimated at $3.3 billion in 2010 dollars. POSITIVE IMPACTS: Implementation would maintain or improve future traffic levels of service, provide a facility that is compatible with future bus rapid transit and other modal options, provide consistency with the regional transportation plan, and maintain I-5 as an effective link in the national strategic highway network. Longer bridge lengths would enhance lagoon function. NEGATIVE IMPACTS: Construction of the LPA would result in 249 acres of new impervious area and require mitigation for impacts to farmland and federal wetlands. A total of 17.6 acres of wetlands and 62.6 acres of sensitive upland habitat would be impacted. Changes to the existing visual environment along the project corridor would make it noticeably more urban.

PGAA proposes a superior sensitivity and accuracy for elemental quantification under ideal experimental and measurement conditions [1]. One major complication in PGAA is the low signal to noise ratio, due to high background encountered and sensitivity issues, due to sample matrix and shape [2]. One of the newly applied techniques to overcome some of these issues is the use of Multi Prompt Gamma Activation (MPGA) measurement systems [3]. The detection limits for some important elements and energy resolution in gamma spectroscopy are shown to substantially improve by using multi gamma ray spectroscopy systems compared to single detector systems for PGAA applications [4].

This technique has been applied to two challenges of national need - nuclear forensics and rare earth elements (REE). In today's climate, the threat of illicit and clandestine nuclear activities has become a major concern for Homeland Security and has enhanced the necessity for accurate, sensitive, and rapid analytical and forensic techniques to detect and characterize nuclear materials. Rare earth elements are utilized as critical components in a number of industrial applications including automobiles, lasers, solid-oxide fuel cells, and defense technologies.[1] Several REEs, including cerium (Ce), lanthanum (La), and neodymium (Nd), are listed as critical or near-critical with regard to the risk for supply interruption by the U.S. Department of Energy 2011 Critical Materials Strategy Summary.[2] The identification and measurement of these REEs in new domestic sources is an emerging priority.

It can occur in high concentrations in products used for human consumption, for example as arsenate of geological origin in some drinking waters. Regulations have set strict limits on this particular source in many countries; however arsenic is abundant in many human foods and almost daily there is news of "high" mass fractions of the element being found in food items. This ranges from food staples such as rice, meats, and vegetables to infant formula. Arsenic is also widely found in marine organisms, mainly as organic arsenical compounds, since it can be bioaccumulated in marine food chains. As its toxicity depends on the compound, it is desirable to monitor the mass fractions of the individual compounds in risk assessment and control, with such measurements supported by reference materials.

The river has long been overallocated. Climate models project runoff losses of 5-20% from the basin by mid-21st century due to human-induced climate change. Recent work has shown that decreased snow albedo from anthropogenic dust loading to the CO mountains shortens the duration of snow cover by several weeks relative to conditions prior to western expansion of the US in the mid-1800s, and advances peak runoff at Lees Ferry, Arizona, by an average of 3 weeks. Increases in evapotranspiration from earlier exposure of soils and germination of plants have been estimated to decrease annual runoff by more than 1.0 billion cubic meters, or 5% of the annual average. This prior work was based on observed dust loadings during 2005-2008; however, 2009 and 2010 saw unprecedented levels of dust loading on snowpacks in the Upper Colorado River Basin (UCRB), being on the order of 5 times the 2005-2008 loading. Building on our prior work, we developed a new snow albedo decay parameterization based on observations in 2009/10 to mimic the radiative forcing of extreme dust deposition. We convolve low, moderate, and extreme dust/snow albedos with both historic climate forcing and two future climate scenarios via a delta method perturbation of historic records. Compared to moderate dust, extreme dust absorbs 2 to 4 the solar radiation, and shifts peak snowmelt an additional 3 weeks earlier to a total of 6 weeks earlier than pre-disturbance. The extreme dust scenario reduces annual flow volume an additional 1% (6% compared to pre-disturbance), a smaller difference than from low to moderate dust scenarios due to melt season shifting into a season of lower evaporative demand. The sensitivity of flow timing to dust radiative forcing of snow albedo is maintained under future climate scenarios, but the sensitivity of flow volume reductions decreases with increased climate forcing. These results have implications for water management and suggest that dust abatement efforts could be an important component of any climate adaptation strategies in the UCRB.

(1999) Meteoroids 1998:37-54]), although rare in recorded history, give sobering testimony to civilization's inherent vulnerability. A not-so-subtle reminder came on the morning of February 15, 2013, when a large meteoroid hurtled into the Earth's atmosphere, forming a superbolide near the city of Chelyabinsnk, Russia, approximately 1,500 km east of Moscow, Russia [Ivanova MA, et al. (2013) Abstracts of the 76th Annual Meeting of the Meteoritical Society, 5366]. The object exploded in the stratosphere, and the ensuing shock wave blasted the city of Chelyabinsk, damaging structures and injuring hundreds. Details of trajectory are important for determining its specific source, the likelihood of future events, and potential mitigation measures. Earth-viewing environmental satellites can assist in these assessments. Here we examine satellite observations of the Chelyabinsk superbolide debris trail, collected within minutes of its entry. Estimates of trajectory are derived from differential views of the significantly parallax-displaced [e.g., Hasler AF (1981) Bull Am Meteor Soc 52:194-212] debris trail. The 282.7 + or - 2.3 degrees azimuth of trajectory, 18.5 + or - 3.8 degrees slope to the horizontal, and 17.7 + or - 0.5 km/s velocity derived from these satellites agree well with parameters inferred from the wealth of surface-based photographs and amateur videos. More importantly, the results demonstrate the general ability of Earth-viewing satellites to provide valuable insight on trajectory reconstruction in the more likely scenario of sparse or nonexistent surface observations.

Previous studies indicate that when an entire person is visible, we rely strongly on the face for identification, even if the body can be useful. We measured the utility of the face versus body for identification, by using images of unfamiliar people that varied in the quality of identity information in the face. Face quality was varied using similarity scores generated by state-of-the-art face recognition algorithms from an international competition. These algorithms estimated the similarity of faces in a large set (>1000000) of image pairs that showed ‘people’, including the face and the top half of the body. By using these similarity scores, image pairs were stratified into three groups representing good, moderate, and poor performance for the face recognition algorithm. Participants matched identity in image pairs sampled from the three groups, by using versions of the stimuli edited digitally to show only the face or body. Consistent with the algorithm stratifications, performance with the face declined across the three conditions. The face supported more accurate identification than the body in the good and moderate conditions. In the poor condition, performance from the face and body was comparable. Using data from a previous study, we compared the face-only and body-only identity judgments with judgments based on the original image. The original unedited image supported the best overall performance in the good and moderate conditions. Notably, performance in the poor condition was equivalent for the face, body, and original images. The results indicate that in poor viewing conditions, identification decisions from the body may be as accurate as those made from the face or the entire person.

The spatio-temporal distribution of oxygen, nutrient and metal concentrations as well as the organic carbon and nitrogen contents in surficial sediments were determined and diffusive oxygen fluxes were calculated. In order to assess the source of organic carbon (OC) in the two estuaries, the isotopic composition of carbon (delta (super 13) C) was also measured. The temporal variation of organic matter recycling was studied during four seasons in order to understand the driving forces of sediment mineralization and storage in these temperate estuaries. Low spatial variability of vertical profiles of oxygen, nutrient, and metal concentrations and diffusive oxygen fluxes were monitored at the station scale (within meters of the exact location) and cross-section scale. We observed diffusive oxygen fluxes around 15 mmol m (super -2) day (super -1) in the Elorn estuary and 10 mmol m (super -2) day (super -1) in the Aulne estuary. The outer (marine) stations of the two estuaries displayed similar diffusive O (sub 2) fluxes. Suboxic and anoxic mineralization was large in the sediments from the two estuaries as shown by the rapid removal of very high bottom water concentrations of NO (sub x) (super -) (>200 mu M) and the large NH (sub 4) (super +) increase at depth at all stations. OC contents and C/N ratios were high in upstream sediments (11-15% d.w. and 4-6, respectively) and decreased downstream to values around 2% d.w. and C/N < or = 10. delta (super 13) C values show that the organic matter has different origins in the two watersheds as exemplified by lower delta (super 13) C values in the Aulne watershed. A high increase of delta (super 13) C and C/N values was visible in the two estuaries from upstream to downstream indicating a progressive mixing of terrestrial with marine organic matter. The Elorn estuary is influenced by human activities in its watershed (urban area, animal farming) which suggest the input of labile organic matter, whereas the Aulne estuary displays larger river primary production which can be either mineralized in the water column or transferred to the lower estuary, thus leaving a lower mineralization in Aulne than Elorn estuary. This study highlights that (1) meter scale heterogeneity of benthic biogeochemical properties can be low in small and linear macrotidal estuaries, (2) two estuaries that are geographically close can show different pattern of organic matter origin and recycling related to human activities on watersheds, (3) small estuaries can have an important role in recycling and retention of organic matter.

The watershed is heavily urbanized in its downstream portion. Water samples were collected from May 2010 to December 2011, at three localities along the main stem river, 1 location at its Semenyih tributary and from an upstream groundwater source. Concentration and delta (super 13) C data of riverine DIC and DOC indicate the dominance of C3 plant-derived material as the primary source of carbon, with delta (super 13) C (sub DIC) values enriched in (super 13) C relative to that of the C3 source. This enrichment is likely due to CO (sub 2) outgassing, as calculated concentrations of riverine CO (sub 2) are significantly higher than ambient atmospheric values, with methanogenic activity a theoretically possible contributing factor, particularly at the upstream location. The Langat River therefore acts as a net source of CO (sub 2) , with a total sub-basin flux of 19.7 X 10 (super 3) t C year (super -1) . This is comparable to the sum of riverine DOC, DIC and POC loss rates from the sub-basin, calculated as 24.5 X 10 (super 3) t C year (super -1) , and highlights the significance of CO (sub 2) evasion from water bodies to the atmosphere for balancing the budget of the terrestrial carbon cycle. The DIC and DOC concentration and delta (super 13) C data also suggests that in the more urbanized downriver areas, much of the organic carbon input may be anthropogenicaly derived due to ubiquity of sewage treatment plants and landfill sites. Such human-induced perturbations to riverine carbon cycling should be taken into account in future studies of urbanized watersheds.

They thus play an important, yet poorly constrained, role for global biogeochemical cycles and climate. This manuscript reviews recent developments in the modelling of estuarine biogeochemical dynamics. The first part provides an overview of the dominant physical and biogeochemical processes that control the transformations and fluxes of carbon and nutrients along the estuarine gradient. It highlights the tight links between estuarine geometry, hydrodynamics and scalar transport, as well as the role of transient and nonlinear dynamics. The most important biogeochemical processes are then discussed in the context of key biogeochemical indicators such as the net ecosystem metabolism (NEM), air-water CO (sub 2) fluxes, nutrient-filtering capacities and element budgets. In the second part of the paper, we illustrate, on the basis of local estuarine modelling studies, the power of reaction-transport models (RTMs) in understanding and quantifying estuarine biogeochemical dynamics. We show how a combination of RTM and high-resolution data can help disentangle the complex process interplay, which underlies the estuarine NEM, carbon and nutrient fluxes, and how such approaches can provide integrated assessments of the air-water CO (sub 2) fluxes along river-estuary-coastal zone continua. In addition, trends in estuarine biogeochemical dynamics across estuarine geometries and environmental scenario are explored, and the results are discussed in the context of improving the modelling of estuarine carbon and CO (sub 2) dynamics at regional and global scales.

To acquire knowledge concerning the future consequences of ocean acidification (OA), researchers have relied on incubation experiments with organisms exposed to future seawater conditions, numerical models, evidence from the geological record, and recently, observations from aquatic environments exposed to naturally high CO (sub 2) and low pH, e.g., owing to volcanic CO (sub 2) vents, upwelling, and groundwater input. In the present study, we briefly evaluate the distribution of dissolved CO (sub 2) -carbonic acid parameters at (1) two locations in the Pacific and the Atlantic Ocean as a function of depth, (2) a mangrove environment in Bermuda, (3) a seasonally stratified body of water in a semi-enclosed sound in Bermuda, and (4) in temporarily isolated tide pools in Southern California. We demonstrate that current in situ conditions of seawater pCO (sub 2) , pH, and CaCO (sub 3) saturation state (Omega ) in these environments are similar or even exceed the anticipated changes to these parameters in the open ocean over the next century as a result of OA. The observed differences between the Pacific and Atlantic Oceans with respect to seawater CO (sub 2) -carbonic acid chemistry, preservation of CaCO (sub 3) minerals, and the occurrence and distribution of deep-sea marine calcifiers, support the hypothesized negative effects of OA on the production and preservation of CaCO (sub 3) in surface seawater. Clues provided from shallow near-shore environments in Bermuda and Southern California support these predictions, but also highlight that many marine calcifiers already experience relatively high seawater pCO (sub 2) and low pH conditions.

This study, which includes data from June 2008 to December 2011, is part of an integrated effort to understand the factors that influence the dynamics of CO (sub 2) -carbonic acid system parameters in waters surrounding Pacific high-island coral reef ecosystems and subject to differing natural and anthropogenic stresses. The MAPCO (sub 2) buoys are located on the Kaneohe Bay backreef, and fringing reef sites on the south shore of Oahu, Hawaii. The buoys measure CO (sub 2) and O (sub 2) in seawater and in the atmosphere at 3-h intervals, as well as other physical and biogeochemical parameters (conductivity, temperature, depth, chlorophyll-a, and turbidity). The buoy records, combined with data from synoptic spatial sampling, have allowed us to examine the interplay between biological cycles of productivity/respiration and calcification/dissolution and biogeochemical and physical forcings on hourly to inter-annual time scales. Air-sea CO (sub 2) gas exchange was also calculated to determine whether the locations were sources or sinks of CO (sub 2) over seasonal, annual, and interannual time periods. Net annualized fluxes for CRIMP-2, Ala Wai, and Kilo Nalu over the entire study period were 1.15, 0.045, and -0.0056 mol C m (super -2) year (super -1) , respectively, where positive values indicate a source or a CO (sub 2) flux from the water to the atmosphere, and negative values indicate a sink or flux of CO (sub 2) from the atmosphere into the water. These values are of similar magnitude to previous estimates in Kaneohe Bay as well as those reported from other tropical reef environments. Total alkalinity (A (sub T) ) was measured in conjunction with pCO (sub 2) , and the carbonic acid system was calculated to compare with other reef systems and open ocean values around Hawaii. These findings emphasize the need for high-resolution data of multiple parameters when attempting to characterize the carbonic acid system in locations of highly variable physical, chemical, and biological parameters (e.g., coastal systems and reefs).

The annual estuarine DSi mass-balance was established, based on seasonal fluxes estimated using measured DSi concentrations and (fully transient) model simulations of conservative transport. The annual BSi mass-balance was deduced from measured BSi contents in the suspended particulate matter and annual mud fluxes taken from the literature. The Scheldt estuary acted as a net sink not only for the BSi carried by the tidal river as well as that produced by diatoms in the estuary, but also for large amounts of BSi imported from the coastal zone. This results in the retention of dissolved and biogenic silica higher than that of DSi alone, which is in contrast with the classical consideration that rivers act as a source of BSi for the coastal zone. DSi and silica (DSi + BSi) retentions amounted to, respectively, 28 and 64% in the estuary, and 33 and 66% in the entire tidal system. This study highlights thus the predominant role of the estuary in the entire Scheldt tidal system when dealing with silica dynamics, as well as the importance of including BSi when investigating estuarine silica retention.

Analysis of end-members specific to the study site indicates that the bulk OM pool cannot be modeled as a simple mixture of two end-members (terrestrial vs. marine OM), but rather reflects a more complex, multicomponent mixture. Mangrove, coral reef ecosystems, and bacterial biomass contribute OM to tropical coastal marine sediments that is compositionally distinct from traditional marine and terrestrial end-members and thus preclude the application of a classical two end-member mixing model of the sort that has been used traditionally in sediments from temperate environments. A survey of elemental ratios and carbon isotopic values of potential OM end-members reported in the literature, as well as depth profiles before and after whole-core incubation experiments conducted as part of this study, were used to evaluate the strength of OC:TN versus OC:OP ratios as OM source indices. Our study suggests that OC:TN ratios are a weaker indicator of OM source than OC:OP ratios, because: (1) the more restricted dynamic range of OC:TN ratios prevents clear distinction of terrestrial-from marine-derived OM, and (2) post-depositional changes in OC:TN ratios occur during diagenesis, obscuring the source signature of initially deposited OM. The fidelity of OM indices during early diagenesis underscores the importance of quantifying OP in sediments to assess sedimentary OM source.

The model consists of 18 reservoirs in the domains of the atmosphere, land, and ocean. The biotic reservoirs on land and in the ocean (N-fixing plants, non-N-fixing plants, and marine biota) interact with atmospheric N (sub 2) and dissolved inorganic nitrogen (DIN, consisting of N (sub 2) , NO (sub 3) (super -) , and NH (sub 4) (super +) ) in the ocean and soil waters. Marine DIN is taken up by marine biota and transformed from ocean particulate organic matter to dissolved organic nitrogen and the ocean sediment. The atmosphere, the largest nitrogen reservoir, supplies N (sub 2) to the system by N fixation, deposition, and dissolution, and these input fluxes are balanced by denitrification and volatilization back to the atmosphere. The land and ocean domains are linked by river transport, which carries both dissolved and particulate nitrogen to the oceanic coastal zone. The isotope-mass balances of the N reservoirs are calculated from the isotopic composition of the reservoirs and the fractionation factors accompanying the fluxes between the reservoirs based on reported values from different natural conditions. The model sensitivity was tested for different biouptake rates and was run with various human perturbations, including fertilization, nitrous oxide emissions, population-related sewage disposal, land-use changes, and temperature-dependent rate kinetics. The new N mass-isotope cycle model provides the basis for assessment of the impact of artificial fertilization between 1700 and 2050. The perturbation experiments in this study suggest that land-use change is the key factor altering the N mass cycle since industrialization.

Here, we use Kaneohe Bay, Hawaii, a semi-enclosed subtropical embayment partially surrounded by a mountainous watershed and fed by river runoff as an example to explore the potential impact of climate change on the pelagic and benthic cycling of nitrogen. We employ a nine-compartment nitrogen cycle biogeochemical box model and perturb it with a set of four idealized climate scenarios. We find that hydrological changes play a dominant role in determining the ecosystem structure, while temperature changes are more important for the trophic state and stability of the ecosystem. The ecosystem stability against storm events does not significantly change under any scenario. The system remains autotrophic in the future; however, it becomes significantly less autotrophic under drier climate, while it turns slightly more autotrophic under wetter climate. These findings may have implications for other high island watershed and coastal ecosystems in the tropics and subtropics.

The weekly data collected at this site, designated as "Point B" since 1957, represent a long-term time series of hydrological conditions in a coastal environment. Since 2007, the historical measurements of hydrological and biological conditions have been complemented by measurements of the CO (sub 2) -carbonic acid system parameters. In this contribution, CO (sub 2) -carbonic acid system parameters and ancillary data are presented for the period 2007-2011. The data are evaluated in the context of the physical and biogeochemical processes that contribute to variations in CO (sub 2) in the water column and exchange of this gas between the ocean and atmosphere. Seasonal cycles of the partial pressure of CO (sub 2) in seawater (pCO (sub 2) ) are controlled principally by variations in temperature, showing maxima in the summer and minima during the winter. Normalization of pCO (sub 2) to the mean seawater temperature (18.5 degrees C), however, reveals an apparent reversal of the seasonal cycle with maxima observed in the winter and minima in the summer, consistent with a biogeochemical control of pCO (sub 2) by primary production. Calculations of fluxes of CO (sub 2) show this area to be a weak source of CO (sub 2) to the atmosphere during the summer and a weak sink during the winter but near neutral overall (range -0.3 to +0.3 mmol CO (sub 2) m (super -2) h (super -1) , average 0.02 mmol CO (sub 2) m (super -2) h (super -1) ). We also provide an assessment of errors incurred from the estimation of annual fluxes of CO (sub 2) as a function of sampling frequency (3-hourly, daily, weekly), using data obtained at the Hawaii Kilo Nalu coastal time-series station, which shows similar behavior to the Point B location despite significant differences in climate and hydrological conditions and the proximity of a coral reef ecosystem.

Here we describe the revision of the database to an open source content management system and conduct a meta-analysis of the global distribution of known active vent fields. The number of known active vent fields has almost doubled in the past decade (521 as of year 2009), with about half visually confirmed and others inferred active from physical and chemical clues. Although previously known mainly from mid-ocean ridges (MORs), active vent fields at MORs now comprise only half of the total known, with about a quarter each now known at volcanic arcs and back-arc spreading centers. Discoveries in arc and back-arc settings resulted in an increase in known vent fields within exclusive economic zones, consequently reducing the proportion known in high seas to one third. The increase in known vent fields reflects a number of factors, including increased national and commercial interests in seafloor hydrothermal deposits as mineral resources. The purpose of the database now extends beyond academic research and education and into marine policy and management, with at least 18% of known vent fields in areas granted or pending applications for mineral prospecting and 8% in marine protected areas.

As a result, many personal sector customers of these institutions would likely be unable to identify any distinguishing characteristics. Indeed, savings institutions and commercial banks sometimes change their charter types without any substantive change in their operations; credit unions may also undergo such a process, and though rare, banks may even convert to credit unions. Nevertheless, in the case of a charter flip, the measure of the institution's output in the national income and product accounts changes substantially. The method used in this article allocates consumption of borrower and depositor services to sectors in a way that is similar to the method used for commercial banks. Over the period shown, interest rates have increased in booms and decreased in recessions. Adapted from the source document.

In the second quarter of 2013, real GDP increased 2.5%. The acceleration in real GDP growth in the third quarter primarily reflected a deceleration in imports and accelerations in inventory investment and in state and local government spending that were partly offset by decelerations in exports, in nonresidential fixed investment, and in consumer spending. Consumer spending slowed in the third quarter, reflecting a deceleration in services that was partly offset by a pickup in goods. The GDP price index increased 1.9% in the third quarter, 0.1 percentage point more than the increase in the price index for gross domestic purchases. The acceleration in government social benefits primarily reflected an upturn in Medicare payments and an acceleration in Medicaid payments. Adapted from the source document.

Model results were compared to long-term observations of currents and temperature made in 2005 at several locations, mostly in its central basin. In the shallow and mostly unstratified western basin circulation is driven by Detroit River inflow (modified to some extent by wind) and is from west to east. In the central basin (which is of intermediate depth and has a relatively flat bottom), the modeled circulation is anticyclonic (clockwise), driven by anticyclonic vorticity in the surface wind, and the thermocline is bowl-shaped, in line with observations. In the deep part of the eastern basin, the thermocline is dome-shaped and circulation is cyclonic (counter-clockwise), due to density gradients (a configuration typical for other large deep lakes), while shallower areas are occupied by anticyclonic circulation driven by anticyclonic wind vorticity. In the central basin, modeled temperature and circulation patterns are quite sensitive to the specification of the wind field. Anticyclonic wind vorticity leads to thinning of the hypolimnion in the central basin and earlier destratification in the fall. Abstract Copyright (2013), . American Geophysical Union.

That plume is the consequence of the coalescence of 10 or more small, individual plumes from chimneys discharging hot, salt-diminished fluid into the near-bottom ocean. At Dante, the discharge encounters ambient horizontal currents with speeds oscillating from near zero to a maximum of approximately 7 cm s (super -1) , speeds which can bend a plume more than 45 degrees from the vertical. Model results are compatible with field measurements of the plume footprint size and vertical velocity both 20 m above the source when earlier estimates for Dante's heat flux of approximately 50 MW drive the convection. The small-scale short period variability of velocities and properties distributions observed in the field is mimicked in model results. Plumes pool above a source during periods of weak cross flows but stream away from the source, with more diluted concentrations and lower rise heights, at other times. Plume distributions, at identical cross-flow speeds, differ whether the flow is accelerating or decelerating. Small changes in background hydrographic profiles create differences in rise heights comparable to those caused by large changes in source buoyancy flux. If put into an entrainment context, results suggest an entrainment coefficient (alpha (sub EFF) ) that varies from approximately 0.11 to approximately 0.025 with increasing height (2-76 m) above the source.

Observations are consistent with a local balance between wind input and breaking dissipation, as described by Philips (1985). The measurements include direct covariance wind stress estimates and wave breaking dissipation rate estimates during a 3 week research cruise to OWS-P. The analysis is extended to a wider range of conditions using observations of wave energy spectra and wind speed during a 2 year mooring deployment at OWS-P. At moderate wind speeds (5-15 m/s), mooring wave spectra are in agreement, within 5% uncertainty, with the forcing implied by standard drag laws and mooring wind measurements. At high wind speeds (>15 m/s), mooring wave spectra are biased low, by 13%, relative to the forcing implied by standard drag laws and mooring wind measurements. Deviations from equilibrium are associated with directionality and variations at the swell frequencies. A spectral wave hindcast accurately reproduces the mooring observations, and is used to examine the wind input. Abstract Copyright (2013), . American Geophysical Union. All Rights Reserved.

As part of a larger research effort by the U.S. Census Bureau to improve race and Hispanic origin questions for the 2020 Census, we tested experimental versions of race and Hispanic origin questions in Spanish. About half of the versions asked about race and Hispanic origin in separate questions, while the rest asked about these constructs in a combined question format. Cognitive interviews with 33 monolingual Spanish-speaking participants indicated that (a) most participants affirmatively claimed Hispanic origin on the separate and combined formats, but had difficulty selecting or declined to select a race category on the separate question formats and (b) most participants perceived few differences between Hispanic origin and race. In comparison with the separate race and Hispanic origin questions, the combined question facilitated more satisfactory self-identifications.

From 1998 to 2009, data from the Tropical Rainfall Measuring Mission (TRMM) Multi-satellite Precipitation Analysis (TMPA) product 3B42, showed that TCs accounted for 5.5%, 7.5%, 6%, 9.5%, and 8.9% of the annual precipitation for impacted over land areas of the Americas, East Asia, South and West Asia, Oceania, and East Africa respectively, and that TC contribution decreased significantly within the first 150 km from the coast. Locally, TCs contributed on average to more than 25% and up to 61% of the annual precipitation budget over very different climatic areas with arid or tropical characteristics. East Asia represented the higher and most constant TC rain (118 mm yr super(-1) plus or minus 19%) normalized over the area impacted, while East Africa presented the highest variability (108 mm yr super(-1) plus or minus 60%), and the Americas displayed the lowest average TC rain (65 mm yr super(-1) plus or minus 24%) despite a higher TC activity. Furthermore, the maximum monthly TC contribution (8-11%) was found later in the TC season and depended on the peak of TC activity, TC rainfall, and the domain transition between dry and wet regimes if any. Finally, because of their importance in terms of rainfall amount, the contribution of TCs was provided for a selection of 50 urban areas experiencing cyclonic activity. Results showed that for particularly intense years, urban areas prone to cyclonic activity received more than half of their annual rainfall from TCs. Key Points * TCs accounted for 5-10% of the annual rainfall over TC basins around the world * EAS represented the higher TC rain, while NCA had the lowest average TC rain * The maximum monthly TC contribution (8-11%) was found later in the TC season JF - Water Resources Research AU - Prat, Olivier P AU - Nelson, Brian R AD - Cooperative Institute for Climate and Satellites, North Carolina State University and NOAA/National Climatic Data Center, Asheville, North Carolina, USA.

The objectives of this study were two-fold: (1) to determine if Coho Salmon Oncorhynchus kisutch were rearing in estuarine habitats, and (2) to characterize and compare the body length, age, condition, and duration and timing of estuarine occupancy of juvenile Coho Salmon between the two contrasting estuaries. We examined use of estuary habitats with analysis of microchemistry and microstructure of sagittal otoliths in two watersheds of south-central Alaska. Juvenile Coho Salmon were classified as estuary residents or nonresidents (recent estuary immigrants) based on otolith Sr : Ca ratios and counts of daily growth increments on otoliths. The estuaries differed in water source (glacial versus snowmelt hydrographs) and in relative estuarine and watershed area. Juvenile Coho Salmon with evidence of estuary rearing were greater in body length and condition than individuals lacking evidence of estuarine rearing. Coho Salmon captured in the glacial estuary had greater variability in body length and condition, and younger age-classes predominated the catch compared with the nearby snowmelt-fed, smaller estuary. Estuary-rearing fish in the glacial estuary arrived later and remained longer (39 versus 24 d of summer growth) during the summer than did fish using the snowmelt estuary. Finally, we observed definitive patterns of overwintering in estuarine and near shore environments in both estuaries. Evidence of estuary rearing and overwintering with differences in fish traits among contrasting estuary types refute the notion that estuaries function as only staging or transitional habitats in the early life history of Coho Salmon.

Rapid population growth of this invasive predator threatens native fish communities. A bioenergetics model was developed for lionfish (i.e., both species) and then applied to estimate the potential impact of these predators on a reef fish community. We conducted a series of laboratory trials to evaluate consumption and respiration rates between 14 degree C and 32 degree C for lionfish weighing from 20 to 400 g. Water temperature greatly influenced consumption; mean daily consumption rates increased from 14 degree C to 29.7 degree C and declined at 32.5 degree C. Energy density of the prey was the most sensitive parameter in the model and estimates of food consumption corresponded with empirical and laboratory estimates. To realize population-level impacts, we applied the bioenergetics model to a size-structured virtual population of 393 lionfish/ha on a reef in the Bahamas. Model simulations estimated that this population would annually consume 929 kg of prey/ha when feeding at 60% of maximum consumption. This model provides the first comprehensive assessment of lionfish bioenergetics accounting for the effects of size and temperature on prey consumption and improves the capacity to evaluate the trophic impacts of lionfish in the Atlantic Ocean.

The algorithm, which runs operationally at the U.S. National Oceanic and Atmospheric Administration, is applied routinely to a number of sounders from the Polar-Orbiting Operational Environmental Satellites, the Defense Meteorological Satellite Program, and the European Meteorological Operational satellite constellations. The one-dimension variational (1DVAR) methodology, which relies on a forward operator, the Community Radiative Transfer Model, allows for solving the inversion of the radiometric measurements into geophysical parameters which have a direct impact on the brightness temperatures. The parameters that are produced by this Microwave Integrated Retrieval System algorithm include the atmospheric temperature T(p), moisture Q(p), and vertically integrated total precipitable water; and the surface skin temperature and emissivity as well as the hydrometeor products of nonprecipitating cloud liquid water and rain- and ice-water paths. In this algorithm, a simple postprocessing is applied to the 1DVAR-generated emissivity to derive cryospheric products (snow water equivalent and sea-ice concentration) when the data are measured over these surfaces. The postprocessing is also applied to the hydrometeors products to generate a surface rainfall rate. This comprehensive set of sounding, surface, hydrometeor, and cryospheric products generated from SNPP/ATMS is therefore radiometrically consistent, meaning that when input to the forward operator, it will allow the simulation of the actual brightness temperatures measurements within noise levels. The geophysical consistency between the products, also critical, is satisfied due to the physical approach adopted and the geophysical constraints introduced through the correlation matrix used in the variational system. The results shown in this paper confirm that the performances of all products are within the expected accuracy and precision figures and comparable to performances usually obtained with single-parameter-dedicated algorithms, with the added value that the inverted products are both radiometrically and geophysically consistent. Key Points * Performances of ATMS EDRs generated by physical algorithm are good * Assessment in rainy conditions show degraded sounding performances over land * Precipitation, cryospheric, sounding, and surface products inverted consistently JF - Journal of Geophysical Research.

T., Mier, K. L., and Jump, C. M. 2013. Effect of region on the food-related benefits to age-0 walleye pollock (Theragra chalcogramma) in association with midwater habitat characteristics in the Gulf of Alaska - ICES Journal of Marine Science, 70: .In the western Gulf of Alaska (GOA), we compared age-0 juvenile walleye pollock body weight, food habits, and expected growth rates between two regions during 3 years. The benefit to rearing off Kodiak Island vs. in the Semidi Islands vicinity increased among years with body length because larger fish consumed more euphausiids, and euphausiids were apparently more available in the Kodiak region. This explains previously observed regional variation in body size, condition, and growth rates within the GOA population and points to potential importance of the Kodiak region as a walleye pollock nursery. During September 2005, 2007, and 2009, Kodiak midwater was cooler and saltier than Semidi midwater, presumably due to a relatively narrow continental shelf and greater oceanic influence. Zooplankton composition differed between regions with the greater euphausiid population density off Kodiak being most relevant to walleye pollock food habits. As found historically, age-0 walleye pollock abundance was lower in the Kodiak region than in the Semidi region. However, the Kodiak fish were larger in both length and length-specific weight, and had fuller stomachs than Semidi fish, although differences were not significant in all years. Regional differences were most pronounced during the relatively warm year 2005 when fish were particularly large. Fish dietary mass was dominated by euphausiids, especially for Kodiak fish greater than or equal to 55 mm standard length. Bioenergetics model output suggests that the greater euphausiid dietary proportion translates into faster growth of the Kodiak fish. The midwater habitat off Kodiak Island might therefore support above-average production of recruits to the GOA adult population due to better condition and likely survival of walleye pollock juveniles, especially when fish are large and thus able to more fully exploit euphausiids, but confirmation of above-average production of recruits depends on our ability to determine spatial structure in juvenile-adult population connectivity.

Errors in species classification are often evident in such surveys, yet few statistical methods exist to properly account for them. In this paper, we examine biases that result from species misidentification when ignored, and we develop statistical models to provide unbiased estimates of density in the face of such errors. Our approach treats true species identity as a latent variable and requires auxiliary information on the misclassification process (such as informative priors, experiments using known species, or a double-observer protocol). We illustrate our approach with simulated census data and with double-observer survey data for ice-associated seals in the Bering Sea. For the seal analysis, we integrated misclassification into a model-based framework for distance-sampling data. The simulated data analysis demonstrated reliable estimation of animal density when there are experimental data to inform misclassification rates; double-observer protocols provided robust inference when there were "unknown" species observations but no outright misclassification. or when misclassification probabilities were symmetric and a symmetry constraint was imposed during estimation. Under our modeling framework, we obtained reasonable apparent densities of seal species even under considerable imprecision in species identification. We obtained more reliable inferences when modeling variation in density among transects. We argue that ecologists should often use spatially explicit models to account for differences in species distributions when trying to account for species misidentification. Our results support using double-observer sampling protocols that guard against species misclassification (i.e., by recording uncertain observations as "unknown").

Assuming that vertebral band pairs were deposited annually, we estimated ages up to 22 years (228 cm FL) for males and 24 years (244 cm FL) for females. The growth of both sexes was similar until approximately age 8 (185 cm FL), after which male growth slowed. The growth of females slowed at a later age ( similar to age 12) than that of males. Relative goodness of fit for all candidate models supported the separate modeling of sexes. For males, von Bertalanffy growth parameters generated from the vertebral data using a set size at birth (81 cm FL) provided the best fit for the band counts (asymptotic length [L sub( infinity ) ] = 225.4 cm FL; growth coefficient [k] = 0.17). For females, the standard three-parameter von Bertalanffy growth model provided the best fit to the band counts (L sub( infinity ) = 274.5 cm FL; k = 0.09; theoretical age at a length of zero [t sub(0)] = -4.82). These are the first growth parameters generated for Common Thresher Sharks in the WNA and can be used to make informed decisions for the management of this species.

Males ranged in size from 78 to 237 cm FL and females ranged from 62 to 263 cm FL. The onset of maturity in males was best described by an inflection in the relationship of clasper length to FL in combination with the degree of clasper calcification. Males matured between 181 and 198 cm FL, and estimated median size at maturity was 188 cm FL. In females, changes in the relationship between ovary and uterus length and width with FL were used to estimate the size at maturity. Females matured between 208 and 224 cm FL; the estimated median size at maturity was 216 cm FL. Litter sizes averaged 3.7 young. The period of parturition is protracted, spanning late spring to late summer (May-August). As in other Lamniformes, young are nourished through oophagy. The proportion of mature females in the resting, pregnant, and postpartum stages provides evidence that indicates that the Common Thresher Shark does not reproduce annually.

BRI maintains one of the only full scale wind tunnel facilities in the world designed specifically for fire experimentation; the Fire Research Wind Tunnel Facility (FRWTF). The coupling of the NIST Firebrand Generator and BRI's FRWTF is leading to progress in assessing vulnerabilities of structures to a firebrand attack. A brief summary of key results to date using the NIST Dragon installed in the FRWTF are provided in this paper as well as a description of the new and improved NIST Dragon's LAIR (Lofting and Ignition Research) facility. The Dragon's LAIR is the only experimental facility capable of simulating continuous wind driven firebrand showers at bench scale. This paper marks the first occasion that all of these findings have been compiled to provide a complete story.

Increasing technological advances, however, have produced statistical challenges in analysing such highly autocorrelated data. Weighted distribution methods have been proposed for analysing RSFs with telemetry data. However, they can be computationally challenging due to an intractable normalizing constant and cannot be aggregated (i.e. collapsed) over time to make space-only inference. In this study, we take a conceptually different approach to modelling animal telemetry data for making RSF inference. We consider the telemetry data to be a realization of a space-time point process. Under the point process paradigm, the times of the relocations are also considered to be random rather than fixed. We show the point process models we propose are a generalization of the weighted distribution telemetry models. By generalizing the weighted model, we can access several numerical techniques for evaluating point process likelihoods that make use of common statistical software. Thus, the analysis methods can be readily implemented by animal ecologists. In addition to ease of computation, the point process models can be aggregated over time by marginalizing over the temporal component of the model. This allows a full range of models to be constructed for RSF analysis at the individual movement level up to the study area level. To demonstrate the analysis of telemetry data with the point process approach, we analysed a data set of telemetry locations from northern fur seals (Callorhinus ursinus) in the Pribilof Islands, Alaska. Both a space-time and an aggregated space-only model were fitted. At the individual level, the space-time analysis showed little selection relative to the habitat covariates. However, at the study area level, the space-only model showed strong selection relative to the covariates. The authors provide a novel method for analyzing telemetry data for resource selection inference using a space-time point process model. The method extends previous weighted distribution methods for easier implementation. In addition, they provide some corrections to previous space-only point process methods to help mitigate effects of location autocorrelation.

This refreezing signature is observed within the low-level subfreezing air as an enhancement of differential reflectivity ZDR and specific differential phase KDP and a decrease of radar reflectivity factor at horizontal polarization ZH and copolar correlation coefficient hv. It is distinct from the overlying melting-layer brightband signature and suggests that unique microphysical processes are occurring within the layer of hydrometeor refreezing. The signature is analyzed for four ice-pellet cases in central Oklahoma as observed by two polarimetric radars. A statistical analysis is performed on the characteristics of the refreezing signature for a case of particularly long duration. Several hypotheses are presented to explain the appearance of the signature, along with a summary of the pros and cons for each. It is suggested that preferential freezing of small drops and local ice generation are plausible mechanisms for the appearance of the ZDR and KDP enhancements. Polarimetric measurements and scattering calculations are used to retrieve microphysical information to explore the validity of the hypotheses. The persistence and repetitiveness of the signature suggest its potential use in operational settings to diagnose the transition between freezing rain and ice pellets.

Here, we show that people rely on the body but are unaware of doing so. State-of-the-art face-recognition algorithms were used to select images of people with almost no useful identity information in the face. Recognition of the face alone in these cases was near chance level, but recognition of the person was accurate. Accuracy in identifying the person without the face was identical to that in identifying the whole person. Paradoxically, people reported relying heavily on facial features over noninternal face and body features in making their identity decisions.

The simulations generally indicate drier summers in the future over most of Colorado and the border regions of the adjoining states. The decrease in precipitation occurs despite an increase in the surface specific humidity. The domain-averaged decrease in daily summer precipitation occurs in all of the models from the 50th through the 95th percentile, but without a clear agreement on the sign of change for the most extreme (top 1% of) events.

This study examined the effect of an interactive, community-based, media literacy and dissonance wellness program, In Favor of Myself, on the self-image, body image, eating attitudes and behavior of young adolescents. A preliminary cohort study was conducted among 972 program participants who did not take part in the controlled trial. Over 75% of participants said they would recommend the program to their friends. Methods A controlled trial was conducted to evaluate program acceptability, efficacy and effectiveness among 259 participants (210 in the intervention group and 49 in the control group), aged 12-14 years, who completed questionnaires during at least two assessment times. Program materials were provided, along with leaders' training, in order to ensure quality program delivery and creation of a wide network of committed program leaders. Results The program significantly reduced drive for thinness and self-worth contingent upon others' approval, the gap between current body figure and ideal figure, and the impact of mood on girls' self-image. Superiority was found among those participating in the intervention group with respect to recognizing media strategies, the influence of media on desire to change, and the influence of appearance on self-confidence and drive for thinness. Conclusions In Favor of Myself shows promising results for strengthening adolescents' ability to cope with the challenges of their life stage. Suggestions for improving In Favor of Myself are presented.

We here consider resolution improvements obtainable by treating the sonic anemometer as a small tomography array, with application of appropriate inverse algorithms for the reconstruction of temperature and velocity. A particular modification of the sonic anemometer is considered when the number of its transducers is doubled and the time-dependent stochastic inversion algorithm is used for reconstruction. Numerical simulations of the sonic anemometer and its suggested modification are implemented with the temperature and velocity fields modelled as discrete eddies moving through the sonic's volume. The tomographic approach is shown to provide better reconstructions of the temperature and velocity fields, with spatial resolution increased by as much as a factor of ten. The spatial resolution depends on the inverse algorithm and also improves by increasing the number of transducers.

It usually represents the relative abundance of fished species across a spectrum of TLs. The reality, ubiquity, and causes of a general decline in the MTL of fisheries catch through time, and whether fisheries catch tracks ecosystem level changes, have engendered much attention. However, the consequences of such patterns for broader ecosystem structure and function remain virtually unexplored. Along the Pacific U.S. Coast, previous work has documented fluctuations and a slow increase in ecosystem MTL from 1977 to 2004. Here, we document a decline in the ecosystem MTL of groundfishes in the same ecosystem from 2003 to 2011, the proximate cause of which was a decrease in the biomass of higher TL groundfishes. Using a food web model, we illustrate how these shifts in ecosystem structure may have resulted in short term, positive responses by many lower TL species in the broader ecosystem. In the longer term, the model predicts that initial patterns of prey release may be tempered in part by lagged responses of other higher TL species, such as salmon and seabirds. Although ecosystem functions related to specific groups like piscivores (excluding high-TL groundfishes) changed, aggregate ecosystem functions altered little following the initial reorganization of biomass, probably due to functional redundancy within the predator guild. Efforts to manage and conserve marine ecosystems will benefit from a fuller consideration of the information content contained within, and implied by, fisheries-independent TL indicators.

As a first step to study the possibility of future cultivation and harvest of ribbed mussels for nutrient removal from eutrophic urban environments, the feeding behavior of ribbed mussels in situ was studied from July to October 2011. Two locations approximately 80 km apart were used as study sites: Milford Harbor (Connecticut; 41 degree 12'42.46 double prime N, 73 degree 3'7.75 double prime W) and Hunts Point (Bronx, New York; 40 degree 48'5.99 double prime N, 73 degree 52'17.76 double prime W). Total particulate matter was higher at Hunts Point than at Milford Harbor, but the organic content was higher at Milford than at Hunts Point. The relatively low quantity of organic content in Hunts Point seston resulted in a much higher production of pseudofeces by mussels. Mussel clearance and absorption rates were higher at Milford Harbor than at Hunts Point. Nevertheless, mussels at both sites had the same absorption efficiency, suggesting that mussels are able to adapt to conditions at both locations. Ribbed mussels decreased clearance rate when the seston quantity was high at both sites. At Hunts Point, ribbed mussels increased the gut transit time of ingested particles when the amount of inorganic particulates in the water increased. This study does not quantify nutrient removal capacity of G. demissa; however, the environmental tolerance demonstrated here, and current lack of commercial harvest, suggests that this species may be a good candidate for nutrient bioextraction in highly impacted urban environments.

Routine evaluation using near-real-time AIRNow ozone measurements through 2011 showed better performance of the operational ozone predictions. In this work, quality-controlled and -assured Air Quality System (AQS) ozone and nitrogen dioxide (NO sub(2)) observations are used to evaluate the experimental predictions in 2010. It is found that both ozone and NO sub(2) are overestimated over the contiguous US (CONUS), with annual biases of +5.6 and +5.1 ppbv, respectively. The annual root mean square errors (RMSEs) are 15.4 ppbv for ozone and 13.4 ppbv for NO sub(2). For both species the overpredictions are most pronounced in the summer. The locations of the AQS monitoring sites are also utilized to stratify comparisons by the degree of urbanization. Comparisons for six predefined US regions show the highest annual biases for ozone predictions in Southeast (+10.5 ppbv) and for NO sub(2) in the Lower Middle (+8.1 ppbv) and Pacific Coast (+7.1 ppbv) regions. The spatial distributions of the NO sub(2) biases in August show distinctively high values in the Los Angeles, Houston, and New Orleans areas. In addition to the standard statistics metrics, daily maximum eight-hour ozone categorical statistics are calculated using the current US ambient air quality standard (75 ppbv) and another lower threshold (70 ppbv). Using the 75 ppbv standard, the hit rate and proportion of correct over CONUS for the entire year are 0.64 and 0.96, respectively. Summertime biases show distinctive weekly patterns for ozone and NO sub(2). Diurnal comparisons show that ozone overestimation is most severe in the morning, from 07:00 to 10:00 local time. For NO sub(2), the morning predictions agree with the AQS observations reasonably well, but nighttime concentrations are overpredicted by around 100%.

Altering the visual cues associated with fishing gear may reduce sea turtle bycatch. We examined the effectiveness of illuminating gillnets with ultraviolet (UV) light-emitting diodes for reducing green sea turtle (Chelonia mydas) interactions. We found that the mean sea turtle capture rate was reduced by 39.7% in UV-illuminated nets compared with nets without illumination. In collaboration with commercial fishermen, we tested UV net illumination in a bottom-set gillnet fishery in Baja California, Mexico. We did not find any difference in overall target fish catch rate or market value between net types. These findings suggest that UV net illumination may have applications in coastal and pelagic gillnet fisheries to reduce sea turtle bycatch.

Observed dust concentrations at Alert, Canada, are lowest in winter and summer and highest in spring and autumn. In this study, we simulate transport and deposition of dust in a global chemical transport model. The model predicts the spring maximum caused by natural dust from desert sources in Asia and Sahara but underestimates the observations in autumn. Both natural and pollution sources contribute to the wintertime dust burden, as suggested by previous measurements of elemental compositions. Cloud parcel model simulations were carried out to study the impact of dust aerosol on the formation of mixed-phase and ice clouds in the Arctic lower troposphere. The liquid water path of low-level cloud is most sensitive to dust aerosol concentration from winter to early spring when air temperature is at its lowest in the annual cycle. The global and parcel models together suggest that low concentrations and acid coating of dust particles are favorable conditions for occurrence of mixed-phase clouds and that anthropogenic pollution can cause significant perturbations to Arctic IN and clouds in winter.

Surprisingly no study has completed an analogous assessment for the historical period, during which emissions of greenhouse gases increased rapidly and land-use changes (LUC) dramatically altered terrestrial carbon sources and sinks. Using the Geophysical Fluid Dynamics Laboratory comprehensive Earth System Model ESM2G and a reconstruction of the LUC, we estimate that enhanced vegetation growth has lowered the historical atmospheric CO2 concentration by 85 ppm, avoiding an additional 0.31 + or - 0.06 degrees C warming. We demonstrate that without enhanced vegetation growth the total residual terrestrial carbon flux (i.e., the net land flux minus LUC flux) would be a source of 65-82 Gt of carbon (GtC) to atmosphere instead of the historical residual carbon sink of 186-192 GtC, a carbon saving of 251-274 GtC.

The daily and monthly sea ice concentration data are on the National Snow and Ice Data Center (NSIDC) polar stereographic grid with nominal 25 km 25 km grid cells in both the Southern and Northern Hemisphere polar regions from 9 July 1987 to 31 December 2007. The data files are available in the NetCDF data format at http://nsidc.org/data/g02202.html and archived by the National Climatic Data Center (NCDC) of the National Oceanic and Atmospheric Administration (NOAA) under the satellite climate data record program (http://www.ncdc.noaa.gov/cdr/operationalcdrs.html). The description and basic characteristics of the NOAA/NSIDC passive microwave sea ice concentration CDR are presented here. The CDR provides similar spatial and temporal variability as the heritage products to the user communities with the additional documentation, traceability, and reproducibility that meet current standards and guidelines for climate data records.

In particular, for species with overlapping generations, it is easier to estimate the effective number of breeders in one reproductive cycle (Nb) than Ne per generation. We empirically evaluated the relationship between life history and ratios of Ne, Nb and adult census size (N) using a recently developed model (agene) and published vital rates for 63 iteroparous animals and plants. Nb/Ne varied a surprising sixfold across species and, contrary to expectations, Nb was larger than Ne in over half the species. Up to two-thirds of the variance in Nb/Ne and up to half the variance in Ne/N was explained by just two life-history traits (age at maturity and adult lifespan) that have long interested both ecologists and evolutionary biologists. These results provide novel insights into, and demonstrate a close general linkage between, demographic and evolutionary processes across diverse taxa. For the first time, our results also make it possible to interpret rapidly accumulating estimates of Nb in the context of the rich body of evolutionary theory based on Ne per generation.

For the first time, climate models of the Coupled Model Intercomparison Project phase 5 (CMIP5) provided to the Intergovernmental Panel on Climate Change Fifth Assessment Report (IPCC-AR5) in historical simulations have been used for this purpose. The models show the most energetic variability on the multidecadal timescale band both with respect to the AMO and AMOC, but with a large model spread in both amplitude and frequency. The relationship between the AMO and AMOC in most of the models resembles the delayed advective oscillation proposed for the AMOC on multidecadal timescales. A speed up (slow down) of the AMOC is in favor of generating a warm (cold) phase of the AMO by the anomalous northward (southward) heat transport in the upper ocean, which reversely leads to a weakening (strengthening) of the AMOC through changes in the meridional density gradient after a delayed time of ocean adjustment. This suggests that on multidecadal timescales the AMO and AMOC are related and interact with each other. Abstract Copyright (2013), . American Geophysical Union. All Rights Reserved.

Two parallel experiments, the main run and the experimental run, are performed for the period of 2005-2011 with daily atmospheric forcing except that an idealized hourly shortwave radiation diurnal cycle is included in the main run. The results show that the diurnal cycle of solar radiation generally warms the Indian Ocean sea surface temperature (SST) north of 10 degrees S, particularly during the calm phase of the MJO when sea surface wind is weak, mixed layer is thin, and the SST diurnal cycle amplitude (dSST) is large. The diurnal cycle enhances the MJO-forced intraseasonal SST variability by about 20% in key regions like the Seychelles-Chagos Thermocline Ridge (SCTR; 55 degrees -70 degrees E, 12 degrees -4 degrees S) and the central equatorial Indian Ocean (CEIO; 65 degrees -95 degrees E, 3 degrees S-3 degrees N) primarily through nonlinear rectification. The model also well reproduced the upper-ocean variations monitored by the CINDY/DYNAMO field campaign between September-November 2011. During this period, dSST reaches 0.7 degrees C in the CEIO region, and intraseasonal SST variability is significantly amplified. In the SCTR region where mean easterly winds are strong during this period, diurnal SST variation and its impact on intraseasonal ocean variability are much weaker. In both regions, the diurnal cycle also has a large impact on the upward surface turbulent heat flux Q (sub T) and induces diurnal variation of Q (sub T) with a peak-to-peak difference of O(10 W m (super -2) ).

Acidification impairs CaCO (sub 3) shell and skeleton construction by marine organisms. Coral reefs are particularly vulnerable, as they are constructed by the CaCO (sub 3) skeletons of corals and other calcifiers. We understand relatively little about how coral reefs will respond to ocean acidification in combination with other disturbances, such as tropical cyclones. Seawater carbonate chemistry data collected from two reefs in the Florida Keys before, during, and after Tropical Storm Isaac provide the most thorough data to-date on how tropical cyclones affect the seawater CO (sub 2) system of coral reefs. Tropical Storm Isaac caused both an immediate and prolonged decline in seawater pH. Aragonite saturation state was depressed by 1.0 for a full week after the storm impact. Based on current "business-as-usual" CO (sub 2) emissions scenarios, we show that tropical cyclones with high rainfall and runoff can cause periods of undersaturation (Omega < 1.0) for high-Mg calcite and aragonite mineral phases at acidification levels before the end of this century. Week-long periods of undersaturation occur for 18 mol % high-Mg calcite after storms by the end of the century. In a high-CO (sub 2) world, CaCO (sub 3) undersaturation of coral reef seawater will occur as a result of even modest tropical cyclones. The expected increase in the strength, frequency, and rainfall of the most severe tropical cyclones with climate change in combination with ocean acidification will negatively impact the structural persistence of coral reefs.

To improve estimates of HV, DO was subsampled from the output of 3-D model hindcasts at times/locations matching the set of 2004-2005 stations monitored by the Chesapeake Bay Program. The resulting station profiles were interpolated to produce bay-wide estimates of HV in a manner consistent with nonsynoptic, cruise-based estimates. Interpolations of the same stations sampled synoptically, as well as multiple other combinations of station profiles, were examined in order to quantify uncertainties associated with interpolating HV from observed profiles. The potential uncertainty in summer HV estimates resulting from profiles being collected over 2 weeks rather than synoptically averaged approximately 5 km (super 3) . This is larger than that due to sampling at discrete stations and interpolating/extrapolating to the entire Chesapeake Bay (2.4 km (super 3) ). As a result, sampling fewer, selected stations over a shorter time period is likely to reduce uncertainties associated with interpolating HV from observed profiles. A function was derived that when applied to a subset of 13 stations, significantly improved estimates of HV. Finally, multiple metrics for quantifying bay-wide hypoxia were examined, and cumulative hypoxic volume was determined to be particularly useful, as a result of its insensitivity to temporal errors and climate change. A final product of this analysis is a nearly three-decade time series of improved estimates of HV for Chesapeake Bay. Abstract Copyright (2013), . The Authors.

Temporal patterns in resulting background trends cluster into four dominant groups, three of which have increasing trends, the strongest of which extends over the coastal upwelling region from southern Oregon to Point Conception, California, and has a mean of 0.118 mg CHL m (super -3) decade (super -1) . Overall, statistically significant increasing trends are observed over 75% of the study area, 20% of the study area had no trend, and 5% showed decreasing chlorophyll. Location-specific trend estimation shows increases are strongest (> 0.2 mg CHL m (super -3) decade (super -1) ) in upwelling areas along the Washington, Oregon and central California coasts, weaker in regions > 200 km offshore, and that positive trends are statistically significant over most of the California Current north of approximately 27 degrees N. Negative trends are evident south of approximately 31 degrees N off Baja California. These trends remain significant with similar spatial pattern, but lower magnitude, when the 1997-1998 El Nino period is removed from the analysis. State-space models of trends in alongshore wind stress and sea surface temperature over the same period indicate that local mechanisms linked to these chlorophyll trends are not clear. Comparisons of the chlorophyll trends to nonlocal signals, characterized by the North Pacific Gyre Oscillation and the Multivariate El Nino Index, map the spatially varying ecological footprint of these basin-scale signals.

EBIC measurements are performed with a spatial resolution as high as approximately 20 nm both on the top surface and throughout the cross-section of the device, revealing a remarkable degree of electrical inhomogeneity near the p-n junction and enhanced carrier collection in the vicinity of grain boundaries (GB). Simulation results of low energy EBIC suggest that the band bending near a GB is downward, with a magnitude of at least 0.2 eV for the most effective current-collecting GBs. Furthermore, we demonstrate a new approach to investigate local open-circuit voltage by applying an external bias across electrical contact with a point electron-beam injection.

The ambipolar mobility is shown to reduce to zero when the constituent injection-dependent carrier mobilities are taken into account. Modeling of the photoconductivity incorporating the transient, injection-dependent, ambipolar mobility confirms experimental reduction in signal at increasing carrier-generation rates. The onset of the reduction of mobility occurs at approximately 10 times the background carrier density; thus devices that utilize lightly doped materials are susceptible to anomalous injection-based behavior. For photovoltaic applications, high-injection device-performance degradation would result from mobility reduction due to reduced diffusion length.

The separation distance between the primary eyewall and the secondary eyewall can vary from 10 to more than 100 km. The size of the secondary eyewall is a key factor determining the horizontal scale of the destructive winds and heavy rainfall in these TCs. Previous work suggested that the internal dynamic and thermodynamic structure of the TC affects the radial location of secondary eyewall formation. The potential impact of the large-scale environment is examined by using the National Centers for Environmental Prediction-National Center for Atmospheric Research reanalysis and best track data sets in this study. It is found that large secondary eyewalls tend to form in weak storms at relatively high latitudes and in environments with high relative humidity, low sea-level pressure, and high low-level vorticity. The performance of a statistical-dynamical model to predict the size of secondary eyewalls is evaluated, and the physical interpretation of the selected predictors is also provided.

ATMS is a cross-track scanning instrument observing in 22 channels at frequencies ranging from 23 to 183 GHz, permitting the measurements of the atmospheric temperature and moisture under most weather conditions. In this study, the ATMS radiometric calibration algorithm used in the operational system is first evaluated through independent analyses of prelaunch thermal vacuum data. It is found that the ATMS peak nonlinearity for all the channels is less than 0.5 K, which is well within the specification. For the characterization of the ATMS instrument sensitivity or noise equivalent differential temperatures (NEDT), both standard deviation and Allan variance of warm counts are computed and compared. It is shown that NEDT derived from the standard deviation is about three to five times larger than that from the Allan variance. The difference results from a nonstationary component in the standard deviation of warm counts. The Allan variance is better suited than the standard deviation for describing NEDT. In the ATMS sensor brightness temperature data record (SDR) processing algorithm, the antenna gain efficiencies of main beam, cross-polarization beam, and side lobes must be derived accurately from the antenna gain distribution function. However, uncertainties remain in computing the efficiencies at ATMS high frequencies. Thus, ATMS antenna brightness temperature data records (TDR) at channels 1 to 15 are converted to SDR with the actual beam efficiencies whereas those for channels 16 to 22 are only corrected for the near-field sidelobe contributions. The biases of ATMS SDR measurements to the simulations are consistent between GPS RO and NWP data and are generally less than 0.5 K for those temperature-sounding channels where both the forward model and input atmospheric profiles are reliable.

We compared nekton assemblage structure in fall 2009 and spring 2010 among 3 locations and 3 major habitat types (marsh, submerged aquatic vegetation[SAV] dominated by Vallisneria americana, and shallow non-vegetated bottom [SNB]) commonly found throughout the MTD using 1 m super(2) drop samplers. Samplelocations (Tensaw River [TR], Chocolatta Bay [CB], and Below Causeway [BC]) were selected based on their degree of tidal connectivity with the wider estuary (BC > TR > CB). Nekton assemblages varied among locations and habitat types. Recruitment by the young of transient fishery species appeared to drive the nektonassemblage structure at the least hydrologically restricted locations (BC and TR) in the delta, whereas estuarine-resident species dominated the nektonassemblage at CB. Species richness was greater at BC than at CB. Within locations, mean densities of abundant species were concentrated in SAV and marsh.Delta locations directly connected to Mobile Bay, therefore, likely provide an important nursery for fishery species such as white shrimp, blue crab, gulf menhaden,and southern flounder. Additional studies will be needed, however, to determine whether these fishery species represent strong conduits for cross ecosystemtransfer of energy and nutrients between the delta and northern Gulf of Mexico.

Typically, thresholds are subjectively defined as the upper limit of peak rainstorm intensities that do not produce debris flows and landslides, or as the lower limit of peak rainstorm intensities that initiate debris flows and landslides. In addition, peak rainstorm intensities are often used to define thresholds, as data regarding the precise timing of debris flows and associated rainfall intensities are usually not available, and rainfall characteristics are often estimated from distant gauging locations. Here, we attempt to improve the performance of existing threshold-based predictions of post-fire debris-flow occurrence by utilizing data on the precise timing of debris flows relative to rainfall intensity, and develop an objective method to define the threshold intensities. We objectively defined the thresholds by maximizing the number of correct predictions of debris flow occurrence while minimizing the rate of both Type I (false positive) and Type II (false negative) errors. We identified that (1) there were statistically significant differences between peak storm and triggering intensities, (2) the objectively defined threshold model presents a better balance between predictive success, false alarms and failed alarms than previous subjectively defined thresholds, (3) thresholds based on measurements of rainfall intensity over shorter duration (< or =60 min) are better predictors of post-fire debris-flow initiation than longer duration thresholds, and (4) the objectively defined thresholds were exceeded prior to the recorded time of debris flow at frequencies similar to or better than subjective thresholds. Our findings highlight the need to better constrain the timing and processes of initiation of landslides and debris flows for future threshold studies. In addition, the methods used to define rainfall thresholds in this study represent a computationally simple means of deriving critical values for other studies of nonlinear phenomena characterized by thresholds.

Mean April 1 SWE was 0.44 m (56%) above normal averaged over 100 snow sensors. AR occurrence was anomalously high during the period, with 20 AR dates during the season and 14 in the month of December 2010, compared to the mean occurrence of nine dates per season. Fifteen out of the 20 AR dates were associated with the negative phases of the Arctic Oscillation (AO) and the Pacific-North American (PNA) teleconnection pattern. Analysis of all winter ARs in California during water years 1998-2011 indicates more ARs occur during the negative phase of AO and PNA, with the increase between positive and negative phases being approximately 90% for AO, and approximately 50% for PNA. The circulation pattern associated with concurrent negative phases of AO and PNA, characterized by cyclonic anomalies centered northwest of California, provides a favorable dynamical condition for ARs. The analysis suggests that the massive Sierra Nevada snowpack during the 2010/2011 winter season is primarily related to anomalously high frequency of ARs favored by the joint phasing of -AO and -PNA, and that a secondary contribution is from increased snow accumulation during these ARs favored by colder air temperatures associated with -AO, -PNA, and La Nina.

To better understand nutrient cycling in these habitats, we measured the stable isotopic content of carbon and nitrogen in organic and inorganic carbon pools in Middle Island sinkhole, a nearly equal 23 m deep feature influenced by both groundwater and overlying lake water. Two distinct sources of dissolved CO (sub 2) (DIC) were available to primary producers. Lake water DIC (delta (super 13) C = -0.1 ppm) differed by +5.9 ppm from groundwater DIC (delta (super 13) C = -6.0 ppm). Organic carbon fixed by primary producers reflected the two DIC sources. Phytoplankton utilizing lake water DIC were more enriched in (super 13) C (delta (super 13) C = -22.2 to -23.2 ppm) than mat cyanobacteria utilizing groundwater DIC (delta (super 13) C = -26.3 to -30.0 ppm). Sinkhole sediments displayed an isotopic signature (delta (super 13) C = -23.1 ppm) more similar to sedimenting phytoplankton than the cyanobacterial mat. Corroborated by sediment C/N ratios, these data suggest that the carbon deposited in sinkhole sediments originates primarily from planktonic rather than benthic sources. (super 210) Pb/ (super 137) Cs radiodating suggests rapid sediment accumulation and sub-bottom imaging indicated a massive deposit of organic carbon beneath the sediment surface. We conclude that submerged sinkholes may therefore act as nutrient sinks within the larger lake ecosystem.

Three unstructured coastal circulation models (ADCIRC, FVCOM, and SELFE) validated with similar skill on a new common Gulf scale mesh (ULLR) with identical frictional parameterization and forcing for the tidal validation and hurricane hindcasts. Coupled circulation and wave models, SWAN+ADCIRC and WWMII+SELFE, along with FVCOM loosely coupled with SWAN, also validated with similar skill. NOAA's official operational forecast storm surge model (SLOSH) was implemented on local and Gulf scale meshes with the same wind stress and pressure forcing used by the unstructured models for hindcasts of Ike and Rita. SLOSH's local meshes failed to capture regional processes such as Ike's forerunner and the results from the Gulf scale mesh further suggest shortcomings may be due to a combination of poor mesh resolution, missing internal physics such as tides and nonlinear advection, and SLOSH's internal frictional parameterization. In addition, these models were benchmarked to assess and compare execution speed and scalability for a prototypical operational simulation. It was apparent that a higher number of computational cores are needed for the unstructured models to meet similar operational implementation requirements to SLOSH, and that some of them could benefit from improved parallelization and faster execution speed.

Moreover, this species exhibits a number of well-documented effects of polycyclic aromatic hydrocarbon (PAH) exposure. To assess the potential for contaminant exposure during spawning migrations and to track the localized movements of adult English sole in the vicinity of Eagle Harbor, we used acoustic telemetry. In August 2007, we collected 19 English sole from Eagle Harbor, a small embayment of Puget Sound with a long history of PAH contamination and subsequent remediation actions. Fish were surgically implanted with uniquely-coded acoustic transmitters and their movements were tracked via an array of eight submersible receivers inside Eagle Harbor and near its entrance. In addition, we obtained detection data from over 70 other receivers throughout Puget Sound that were maintained by a consortium of regional researchers. All tagged fish were detected immediately after release, and 18 were detected outside of Eagle Harbor at a variety of locations in Puget Sound. Some of these fish made rapid movements across the sound and traveled minimum distances of 32 to 106 km. Half of the fish detected outside Eagle Harbor returned to their capture site in spring 2008, approximately eight months after tagging. This fidelity to summer feeding habitats has important implications for both contaminant studies and flatfish management. In addition, our results illustrate the power of data sharing and the value of pooling resources to maintain large arrays of acoustic receivers.

In the first quarter, real GDP increased 1.1%. The third estimate of real GDP growth for the second quarter is the same as the second estimate released last month and primarily reflects downward revisions to inventory investment and to exports that were offset by an upward revision to state and local government spending. The third estimate of the second-quarter change in real GDP was the same as the second estimate. Downward revisions to inventory investment and to exports were partly offset by an upward revision to state and local government spending.

This approach recognizes the importance of proximity to customers in the delivery of services; many MNCs serve foreign markets, partly or wholly, through their affiliates that are located in, but owned outside of, the markets they serve. In 2012, the cross-border private services surplus increased 8%, to $213.5 billion, after increasing 19% in 2011. In contrast to the persistent US deficit on trade in goods, which was $741.5 billion in 2012, the US has historically recorded a surplus on trade in services. Adapted from the source document.

In 2011, real GDP increased in 277 metropolitan areas. For the US as a whole, real GDP by metropolitan area -- the sum of current-dollar GDP for all metropolitan areas deflated by a national price measure -- increased 2.5% in 2012 after increasing 1.7% in 2011. The new statistics reveal that metropolitan areas of different sizes differed also in terms of economic growth. Much of this can be explained by the industries that are typically concentrated in the areas. Growth in real GDP across US metropolitan areas in 2012 was primarily attributable to growth in durable-goods manufacturing, wholesale and retail trade, and financial activities. Per capita real GDP for metropolitan areas was $45,604 in 2012, 6.6% higher than the national average. Adapted from the source document.

The decrease in the deficit reflected a decrease in the deficit on goods, an increase in the surplus on income, and an increase in the surplus on services. These changes were partly offset by an increase in net outflows of unilateral current transfers. In the financial account, net financial inflows to the US increased to $73.1 billion in the second quarter from $40.4 billion in the first quarter. The statistical discrepancy -- the amount that balances the sum of the recorded credits and debits across all the accounts in the international transactions accounts -- was $25.8 billion in the second quarter, compared with $64.5 billion in the first quarter.

Counterfactual supply is constructed based on the Days-at-Sea system that was recalibrated to meet mandated conservation goals. Due to the decreases in catch that were required to meet those goals, the 2010 policy undoubtedly resulted in worse outcomes for both producers and consumers compared to 2009. However, the conservation-equivalent Days-at-Sea system would have been far worse for both consumers and producers.

Latitudinal variation in size and growth rates of this species greatly exceeded longitudinal variation. Populations of John's Snapper farthest from the equator had the largest body sizes, in line with James's rule, and the fastest growth rates, contrary to the temperature-size rule for ectotherms. A maximum age of 28.6 years, nearly 3 times previous estimates, was recorded and the largest individual was 990 mm in fork length. Females grew to a larger mean asymptotic fork length (L sub( infinity )) than did males, a finding consistent with functional gonochorism. Otolith weight at age and gonad weight at length followed the same latitudinal trends seen in length at age. Length at maturity was 72-87% of L sub( infinity ) and varied by 23% across the full latitudinal gradient, but age at first maturity was consistently in the range of 6-10 years, indicating that basic growth trajectories were similar across vastly different environments. We discuss both the need for complementary reproductive data in age-based studies and the insights gained from experiments where the concept of oxygen- and capacity-limited thermal tolerance is applied to explain the mechanistic causes of James's rule in tropical fish species.

The addition of nuclear RNA as a covariate increased by 4% the classification accuracy of a discriminant analysis model that used cell-cycle, temperature, and standard length to measure larval condition, compared with a model without it. The greatest improvement, a 7% increase in accuracy, was observed for small larvae (<6.00 mm). Nuclear RNA content varied with rearing temperature, increasing as temperature decreased. There was a loss of DNA when larvae were frozen and thawed because the percentage of cells in the DNA synthesis cell-cycle phase decreased, but DNA content was stable during storage of frozen tissue.

We used shark catch data collected during 2006-09 from fishery-independent bottom-longline surveys, as well as biotic and abiotic explanatory data to identify the factors that affect the distribution of coastal sharks at 2 spatial scales in the northern Gulf of Mexico. Centered principal component analyses (PCAs) were used to visualize the patterns that characterize shark distributions at small (Alabama and Mississippi coast) and large (northern Gulf of Mexico) spatial scales. Environmental data on temperature, salinity, dissolved oxygen (DO), depth, fish and crustacean biomass, and chlorophyll-[alpha] (chl-[alpha]) concentration were analyzed with normed PCAs at both spatial scales. The relationships between values of shark catch per unit of effort (CPUE) and environmental factors were then analyzed at each scale with co-inertia analysis (COIA). Results from COIA indicated that the degree of agreement between the structure of the environmental and shark data sets was relatively higher at the small spatial scale than at the large one. CPUE of Blacktip Shark (Carcharhinus limbatus) was related positively with crustacean biomass at both spatial scales. Similarly, CPUE of Atlantic Sharpnose Shark (Rhizoprionodon terraenovae) was related positively with chl-[alpha] concentration and negatively with DO at both spatial scales. Conversely, distribution of Blacknose Shark (C. acronotus) displayed a contrasting relationship with depth at the 2 scales considered. Our results indicate that the factors influencing the distribution of sharks in the northern Gulf of Mexico are species specific but generally transcend the spatial boundaries used in our analyses.

Samples of mature females were collected in the spawning area as part of 2 research surveys conducted in January 2010 and 2011, during the peak of the reproductive season. Batch fecundity (BF) ranged between 40,500 (29 cm total length [TL]) and 2,550,000 (95 cm TL) hydrated oocytes, and was positively correlated with TL, gutted weight, age, hepatosomatic index (HSI), and the relative condition factor (Kn). Relative fecundity ranged between 85 and 1040 hydrated oocytes g super(-1) and showed significant positive relationships with gutted weight, HSI, and Kn; however, coefficients of determination were low for all regressions. Dry weights of samples of 100 hydrated oocytes ranged between 1.8 and 3.95 mg and were positively correlated with all variables analyzed, including batch and relative fecundity. Multiple regression models created with data of the morphophysiological characteristics of females supported maternal influences on fecundity and egg weights. Within the studied size range (29-95 cm TL), larger individuals had better somatic and egg condition, mainly revealed by higher HSI and hydrated oocytes with larger oil droplets (275.71[mu]m [standard error 1.49]). These results were associated with the higher feeding activity of larger females during the spawning season in comparison with the feeding activity of young individuals (<5 years old); the better nutritional state of larger females, assumed to result from more feeding, was conducive to greater production of high-quality eggs.

There can be considerable uncertainty in temperatures of both protected and unprotected steels during fire exposure. This is due to uncertainty in the thermal boundary conditions and thermophysical properties. In this study, uncertainties in both unprotected and protected steel temperatures are estimated with the use of a Monte Carlo method in conjunction with a "Lumped Heat Capacity" approach for estimating steel temperatures. Computed data are compared with experimental measurements obtained during Cardington fire tests (bare steel) and National Institute of Standards and Technology (NIST) World Trade Center (WTC) tests (protected). Reasonable agreement was achieved.

The data derive from the American Community Survey. Using a difference-in-difference design, we compare the target population (ages 19-25) with a control group (ages 26-29). Net private health insurance coverage increased by 4.6 percentage points and overall coverage increased by 4.2 percentage points for people aged 19-25; more for Whites than non-White subgroups. Changes in coverage for states appear driven by demographics rather than the existence of prior dependent expansions by the state. Disparities in health care coverage remain, but the absolute level of coverage is improving. Adapted from the source document.

The "Census moment" for the 2010 Census occurred at 11:59 p.m. on April 1, 2010. This means that, ideally, all persons alive and living in the United States at that moment are included in the Census count, while any person not alive at that moment is excluded. In reality, this goal is challenging to achieve. Since the actual date of data collection often varies widely, it is possible that individuals are included, or excluded, in the count due to this discrepancy between the Census Day and the date of data collection. In this paper, I explore how the Census Bureau addresses this issue specifically when dates of birth after Census Day are encountered. First, I describe the three methods of data collection (Self-administered questionnaires, enumerator-administered questionnaires, and Telephone Questionnaire Assistance/Coverage Follow-Up operator-administered questionnaires), and how dates of birth after Census Day are addressed in each of these methods. Next, I explore related findings from the 2010 Census, including how many dates of birth after Census Day were found in the 2010 Census data, how they were processed according to data collection method, and how this impacted the final Census count. Finally, I discuss the performance of the new procedures related to dates of birth after Census Day that were implemented in the 2010 Census, along with implications for moving forward into future Censuses.

We demonstrate a method for comparing fishery-dependent bycatch to fishery-independent catch to delineate the influence of ecological and social factors on bycatch and provide insights for bycatch management. We used data from commercial fishing vessels in the U.S. west coast trawl groundfish fishery (fishery-dependent data collected by fisheries observers) and scientific data from the U.S. west coast bottom trawl groundfish survey (fishery-independent data) to compare the relative effects of season, time of day, target group, depth, and latitude on the expected catch of 12 bycatch species of management interest. This comparison highlights two important relationships that help identify drivers of bycatch. First, when the effect of season, time of day, depth, or latitude on bycatch in both the commercial and scientific data is positive, ecological processes are likely strong drivers of bycatch, suggesting technical approaches (e.g., temporal or spatial closures, gear modifications) might effectively control bycatch. Alternatively, when the effects of season, time of day, depth, latitude, or target group appear only in the commercial data (but not in survey data), fisher behavior is likely the stronger driver of bycatch, suggesting a need to strengthen incentives for fishers to change behavior to avoid bycatch (e.g., regulatory quotas). Two other patterns emerge that suggest that fishery bycatch is not associated with temporal, target, or spatial variables, implying that either current incentives to avoid bycatch are working (i.e., when survey expected catch is positively correlated with variables, but fishery catch is not) or bycatch is a product of unstudied or stochastic processes (i.e., variables are not correlated with expected catch in either data set) and continued monitoring is recommended. Our analysis provides managers and fishers with a basic analytical framework to assess bycatch reduction alternatives and methods useful for researchers interested in comparing bycatch before and after a management shift.

Part I: Description and Validation via an Observing System Simulation Experiment AN - 1458536250; 18727572 AB - A diabatic Lagrangian analysis (DLA) technique for deriving potential temperature, water vapor and cloud water mixing ratios, and virtual buoyancy from three-dimensional time-dependent Doppler radar wind and reflectivity fields in storms is presented. The DLA method proceeds from heat and water substance conservation along discrete air trajectories via microphysical diabatic heating/cooling and simple damping and surface flux parameterizations in a parcel-following ground-relative reference frame to thermodynamic fields on a regular grid of trajectory endpoints at a common analysis time. Rain and graupel precipitation size distributions are parameterized from observed reflectivity at discrete Lagrangian points to simplify the cloud modelbased microphysically driven heating and cooling rate calculations. The DLA approximates the precipitation size distributions from reflectivity assuming conventional inverse exponential size distributions and prescribed input intercept parameter values based on the output of a mature simulated storm. The DLA is demonstrated via an observing system simulation experiment (OSSE), and its analysis compares favorably with the known output buoyancy and water substance fields in the simulated storm case. The DLA-analyzed thermalsolenoidal horizontal vorticity tendency is of comparable magnitude to the corresponding modeled solenoidal vorticity tendency. A test application of the DLA to a radar-observed storm is presented in a companion paper (Part II).

Inflated reflectivity intensities in the BB often cause positive biases in radar quantitative precipitation estimation (QPE). A vertical profile of reflectivity (VPR) correction is necessary to reduce such biases. However, existing VPR correction methods for ground-based radars often perform poorly for MCSs owing to their coarse resolution and poor coverage in the vertical direction, especially at far ranges. Spaceborne radars such as the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR), on the other hand, can provide high resolution VPRs. The current study explores a new approach of incorporating the TRMM VPRs into the VPR correction for the Weather Surveillance Radar-1988 Doppler (WSR-88D) radar QPE. High-resolution VPRs derived from the Ku-band TRMM PR data are converted into equivalent S-band VPRs using an empirical technique. The equivalent S-band TRMM VPRs are resampled according to the WSR-88D beam resolution, and the resampled (apparent) VPRs are then used to correct for BB effects in the WSR-88D QPE when the ground radar VPR cannot accurately capture the BB bottom. The new scheme was tested on six MCSs from different regions in the United States and it was shown to provide effective mitigation of the radar QPE errors due to BB contamination.

AN - 1448225442; 18713244 AB - Formation and the subsequent evolution of the subtropical mode water (STMW) involve various dynamic and thermodynamic processes. Proper representation of mode water variability and contributions from various processes in climate models is important in order to predict future climate change under changing forcings. The North Atlantic STMW, often referred to as Eighteen Degree Water (EDW), in three coupled models, both with data assimilation [GFDL coupled data assimilation (GFDL CDA)] and without data assimilation [GFDL Climate Model, version 2.1 (GFDL CM2.1), and NCAR Community Climate System Model, version 3 (CCSM3)], is analyzed to evaluate how well EDW processes are simulated in those models and to examine whether data assimilation alters the model response to forcing. In comparison with estimates from observations, the data-assimilating model gives a better representation of the formation rate, the spatial distribution of EDW, and its thickness, with the largest EDW variability along the Gulf Stream (GS) path. The EDW formation rate in GFDL CM2.1 is very weak because of weak heat loss from the ocean in the model. Unlike the observed dominant southward movement of the EDW, the EDW in GFDL CM2.1 and CCSM3 moves eastward after formation in the excessively wide GS in the models. However, the GFDL CDA does not capture the observed thermal response of the overlying atmosphere to the ocean. Observations show a robust anticorrelation between the upper-ocean heat content and airsea heat flux, with upper-ocean heat content leading airsea heat flux by a few months. This anticorrelation is well captured by GFDL CM2.1 and CCSM3 but not by GFDL CDA. Only GFDL CM2.1 captures the observed anticorrelation between the upper-ocean heat content and EDW volume. This suggests that, although data assimilation corrects the readily observed variables, it degrades the model thermodynamic response to forcing.

Potential drivers of sex ratio in projectile biopsy samples from two small delphinids AN - 1448217224; 18723829 AB - Molecular assays were used to determine the sex of 1,294 biopsied common dolphins (658 long-beaked common dolphins, Delphinus capensis, and 636 short-beaked common dolphins, D. delphis) in the Southern California Bight. Sex ratio differed substantially between the two species; females comprised 241 (36.6%) of D. capensis samples and 410 (64.5%) of D. delphis samples. All biopsies were taken either from a large research ship or from a small, rigid-hull inflatable boat (RHIB) launched from the larger ship. When conducting replicate biopsy effort on the same schools from each vessel/platform ("Tandem Biopsy Sampling"), we found evidence that disproportionately more female D. capensis were biopsied from the RHIB than from the ship but the same was not true for D. delphis. We suspect that these results are driven by bowriding-behavior differences between the two species. Biopsy duration, geographic location, school size, and Julian date were considered as potential covariates with sex ratio; geographic location was the only one to show strong evidence of correlation. This study also presents an alternative to the erroneous practice of comparing sex ratios to a theoretical assumption of parity (i.e., 50:50 sex ratio) when researchers avoid sampling animals paired with calves.

Angler noncompliance can severely degrade the ability of fishery managers to avoid overexploitation and to achieve objectives of rebuilding plans. To discern noncompliance in the recreational fishery for Summer Flounder Paralichthys dentatus, we fitted a growth model to 3,474 recapture records from a tagging study conducted by volunteer anglers in Virginia from 2000 to 2011. Most of the tagged fish were small (i.e., sublegal size), and the average time at liberty was 86 d. Based on the growth model, Summer Flounder growth patterns changed at 34.7 cm, possibly representing the length at which the majority of fish reach maturity. The mean size of harvested fish increased in response to increases in the minimum size limit, although harvest of sublegal fish continued. Throughout the 12 years of the study, 33-79% of the tagged fish that were recaptured and harvested were predicted to be sublegal based on the growth model. The percentage of sublegal fish that were harvested increased dramatically when large ( greater than or equal to 5 cm) increases in minimum size limits were implemented. We conclude that Virginia recreational anglers responded to management regulations by adjusting the minimum size of harvested fish but that some anglers continued to harvest sublegal fish.

Data collected during 40,976 km of visual and acoustic shipboard surveys in the tropical Pacific Ocean, including 1,232 detections of 13 species, were examined to determine if changes in dolphin vocal activity could be attributed to the presence of killer whales. Generalized linear models and Random Forest analyses were used to test the hypothesis that dolphin vocal activity was related to the distance and time to the nearest killer whale sighting. Both results show that dolphin vocalizations were inversely correlated with the temporal proximity of killer whales (P <0.05). Despite the relative rarity of killer whales in the tropics, they appear to influence vocal behavior of nearby dolphin schools. This disruption in communication may not significantly impact interactions necessary for survival in tropical waters where killer whale density is low. However, in temperate climates, where increased productivity supports a greater abundance of killer whales, this interruption in communication may have a greater impact. The lower incidence of whistling dolphins in temperate waters may be related to the greater abundance of killer whales in these areas.

AN - 1448211955; 18723834 AB - Molecular phylogenetic analyses conducted over the past 15 yr have consistently had difficulties resolving relationships among the cetacean species in the subfamily Delphininae. In addition, paraphyly of the genera Tursiops and Stenella in these molecular phylogenies has been a recurrent problem since the first appearance of such a phylogeny in 1999, suggesting that these genera do not accurately reflect the evolutionary relationships of the species they contain. Morphological analyses have not resolved the issues. The genera in Delphininae originated in the 19th Century on questionable morphological grounds. The species were nearly all originally described in the genus Delphinus of Linnaeus. Recent molecular phylogenies based on various mitochondrial and nuclear DNA markers have suggested a wide range of possible relationships among these taxa, and several authors have suggested synonymizing all the taxa (Lagenodelphis, Stenella, Sousa, and Tursiops) under Delphinus. Until molecular and/or morphological analyses adequately sort out relationships in this very recently radiated group, one possible solution indeed would be to merge all the delphinine genera with Delphinus. Implications of such a move and alternatives are discussed.Editor's Note: Papers from past Norris Award winners have primarily been a revised or reduced version of the actual presentation given as a plenary talk at the biennial conference. Dr. Perrin requested being allowed to take a topic from his presentation and expand on it to present a set of ideas in the form of an essay that could pass the rigors of the peer-review process. As a result, this Norris Award paper has undergone peer-review and has taken longer than usual for a Norris Award paper to appear in the journal following its presentation at the biennial conference. It also has co-authors, with varying opinions on the issues discussed in the essay, to cover appropriately and more thoroughly those components of the paper that required additional expertise. I believe this approach has produced an excellent, thought-provoking essay and is an approach that should be available to future Norris Award winners if they so choose to take it. Since this essay is meant to elicit dialogue, comments are welcome and will be considered for publication in Letters to the Editor.

Where V (sub S) data are limited, available data are often used to develop and refine map-based proxy models of V (sub S30) for predicting ground-motion intensities. In this paper, we present shallow V (sub S) data from 27 sites in Puerto Rico. These data were acquired using a multimethod acquisition approach consisting of noninvasive, collocated, active-source body-wave (refraction/reflection), active-source surface wave at nine sites, and passive-source surface-wave refraction microtremor (ReMi) techniques. V (sub S) -versus-depth models are constructed and used to calculate spectral response plots for each site. Factors affecting method reliability are analyzed with respect to site-specific differences in bedrock V (sub S) and spectral response. At many but not all sites, body- and surface-wave methods generally determine similar depths to bedrock, and it is the difference in bedrock V (sub S) that influences site amplification. The predicted resonant frequencies for the majority of the sites are observed to be within a relatively narrow bandwidth of 1-3.5 Hz. For a first-order comparison of peak frequency position, predictive spectral response plots from eight sites are plotted along with seismograph instrument spectra derived from the time series of the 16 May 2010 Puerto Rico earthquake. We show how a multimethod acquisition approach using collocated arrays compliments and corroborates V (sub S) results, thus adding confidence that reliable site characterization information has been obtained.

The goal is to explore if the CFSv2 forecasts for the stratosphere would remain skillful beyond the inherent tropospheric predictability time scale of at most 2 weeks. The anomaly correlation between observations and forecasts for temperature field at 50 hPa (T50) in winter seasons remains above 0.3 over the polar stratosphere out to a lead time of 28 days whereas its counterpart in the troposphere at 500 hPa drops more quickly and falls below the 0.3 level after 12 days. We further show that the CFSv2 has a high prediction skill in the stratosphere both in an absolute sense and in terms of gain over persistence except in the equatorial region where the skill would mainly come from persistence of the quasi-biennial oscillation signal. We present evidence showing that the CFSv2 forecasts can capture both timing and amplitude of wave activities in the extratropical stratosphere at a lead time longer than 30 days. Based on the mass circulation theory, we conjecture that as long as the westward tilting of planetary waves in the stratosphere and their overall amplitude can be captured, the CFSv2 forecasts is still very skillful in predicting zonal mean anomalies even though it cannot predict the exact locations of planetary waves and their spatial scales. This explains why the CFSv2 has a high skill for the first EOF mode of T50, the intraseasonal variability of the annular mode while its skill degrades rapidly for higher EOF modes associated with stationary waves. This also explains why the CFSv2's skill closely follows the seasonality and its interannual variability of the meridional mass circulation and stratosphere polar vortex. In particular, the CFSv2 is capable of predicting mid-winter polar stratosphere warming events in the Northern Hemisphere and the timing of the final polar stratosphere warming in spring in both hemispheres 3-4 weeks in advance.

The surface water elevations of the Great Lakes, in particular, are an ideal metric for understanding impacts of climate change on large hydrologic systems, and for assessing adaption measures for absorbing those impacts. In light of the importance of the Great Lakes to the North American and global economies, the Great Lakes and the surrounding region also serve as an important benchmark for hydroclimate research, and offer an example of successful adaptive management under changing climate conditions. Here, we communicate some of the important lessons to be learned from the Great Lakes by examining how the coastline, water level, and water budget dynamics of the Great Lakes relate to other large coastal systems, along with implications for water resource management strategies and climate scenario-derived projections of future conditions. This improved understanding fills a critical gap in freshwater and marine global coastal research.

In this study, benthic invertebrates were collected from 43 streams across four basins and two geographic regions to (1) determine whether invertebrate abundance and community structure are best explained by historic forest harvest, landscape variables or a combination of both, and (2) evaluate associations among harvest, landscape variables, in-stream physical habitat, and invertebrates. Nonmetric multidimensional scaling showed that invertebrate community structure was primarily explained by watershed area and elevation, and basin and region but not by measures of forest harvest. Model selection using an information-theoretic approach and Akaike's information criterion indicated that watershed area was the most important variable explaining clinger and long-lived taxa richness, while basin was the most important variable explaining total abundance, and total, Ephemeroptera, Plecoptera, and Trichoptera taxa richness. Forest harvest ranked lower than landscape variables in relative importance in all models. These results suggest that landscape characteristics were relatively more important in predicting invertebrate community structure than forest harvest, and should therefore be considered when assessing the impacts of both reach and watershed scale forest harvest on benthic communities. Perhaps, the levels of forest harvest examined in this study had only marginal effects on benthic invertebrates because these ecosystems are naturally resilient as a result of frequent disturbance from forest fires.

For calculating forward linkage effects, these studies used the supply-drive(Ghosh in Economica 25(1):58-64, 1958) approach. However, the Ghosh approach has been criticized based on its problematic theoretical interpretation. This study uses an Alaska SAM model to estimate the regional economic impacts of restricting catch of Pacific cod and Atka mackerel in the Aleutian Islands in order to protect Steller sea lions. This study overcomes the problem of calculating forward linkage effects in the previous studies by running the SAM model with (1) changes in output converted to final demand shocks and (2) regional purchase coefficients for all the directly impacted industries (fish harvesting and processing industries) set equal to zero. The impacts of the shift in harvest opportunities in response to the Steller sea lion protection measures are displayed in terms of changes in output, employment, value added, household income, and state and local government revenue.

AN - 1496912084; 15867 AB - PURPOSE: The expansion of military training and testing activities in the Mariana Islands Training and Testing (MITT) study area in the Western Pacific Ocean is proposed. The MITT study area is composed of the established at-sea ranges and land based training areas on Guam and the Commonwealth of the Northern Mariana Islands, operating areas, and special use airspace in the region of the Mariana Islands that are part of the Mariana Islands Range Complex (MIRC) and its surrounding seas. In addition, the study area includes a transit corridor which is outside the geographic boundaries of the MIRC and is a direct route across the high seas for Navy assets in transit between the MIRC and the Hawaii Range Complex (HRC). The proposed action also includes pierside sonar maintenance and testing alongside Navy piers located in Inner Apra Harbor. This overseas EIS updates the analyses contained in the 2010 MIRC EIS and supports reauthorization of incidental takes of marine mammals under the Marine Mammal Protection Act and incidental takes of threatened and endangered marine species under the Endangered Species Act. Three alternatives are analyzed. The No Action Alternative represents continued baseline training and testing activities and force structure requirements as defined by existing Navy environmental planning documents. Alternative 1, which is the preferred alternative, includes the baseline activities plus the expansion of study area boundaries and adjustments to location, type, and tempo of training activities, including the addition of platforms and systems. Boundaries would be expanded to the north of the MIRC within the Exclusive Economic Zone of the Northern Mariana Islands and to the west of the MIRC. The establishment of danger zones for existing shore-based small arms and explosive ordnance disposal ranges and a nearshore small arms training area is also under consideration. Proposed changes to training and testing would accommodate: 1) the relocation of ships, aircraft, and personnel; 2) planned aircraft, vessels, and weapons systems; and 3) ongoing activities not addressed in previous documentation. Net explosive weight for underwater detonations would increase from 10 pounds (lb.) to 20 lb. at Agat Bay Mine Neutralization Site and Outer Apra Harbor Underwater Detonation Site. Alternative 2 consists of all activities that would occur under Alternative 1 plus adjustments to the type and tempo of training and testing activities. This alternative is contingent upon potential budget increases, strategic necessity, and future training and testing requirements. Alternative 2 would include: 1) the addition of three major at-sea training activities (Fleet Strike Group Exercise, Integrated Anti- Submarine Warfare Exercise, and Ship Squadron Anti-Submarine Warfare Exercise) conducted in the study area; and adjustments to Alternative 1 for Naval Air Systems Command and Naval Sea Systems Command testing activities. POSITIVE IMPACTS: Conducting training and testing within the MIRC would ensure that the Navy meets its mission, which is to maintain, train, and equip combat-ready naval forces capable of winning wars, deterring aggression, and maintaining freedom of the seas. NEGATIVE IMPACTS: Changes to sediments, water quality, and air quality would be minor and localized. Most detonations would occur at or near the surface, and those that do occur on the seafloor would be located in primarily soft-bottom habitat. Use of sonar and underwater explosives may result in mortality and harassment of wildlife, but impacts are not expected to decrease the overall fitness of any marine mammal, sea turtle, marine bird, or fish population. Terrestrial species may be injured or killed, but impacts are not expected to decrease the overall fitness of any given population. Under all alternatives, explosive detonations and other activities on Farallon de Medinilla (FDM) have the potential to disturb, injure, or kill the Mariana fruit bat, Micronesian megapode, and seabirds that nest or visit FDM.

In this work, an ensembles of hypothetical imperviousness scenarios created for two small (< 1 ha) watersheds were incorporated into the Gridded Surface Subsurface Hydrologic Analysis (GSSHA) model, which was calibrated against 41 runoff events under natural conditions. Each event was re-simulated for each imperviousness scenario. Variations in the model-projected changes in runoff were characterized and related to temporal rainfall dispersion, ASM, and two metrics: a) proximity of imperviousness from the outlet and b) normalized number of downstream pervious elements. Key findings include the following. First, inter-scenario variations in the simulated runoff were relatively subdued on an event-mean basis but were much wider for individual events. For example, coefficient of variation (CV) was less than 7.8% for runoff peak but was beyond 20% for certain events. Second, the rate of increase in simulated runoff peaks with elevated imperviousness tends to be lower for events with higher temporal rainfall dispersion and ASM, with one of the largest events exhibiting the slowest rate of increase. Third, both metrics were found to be negatively correlated with simulated runoff depth. These findings point to the possibility of refining the model projection by incorporating indicators of overall locations of impervious areas, rainfall dispersion and soil moisture conditions.

The Australian populations are relatively small and their distribution is limited to remote areas in the northern part of the country. Previous global genetic studies of olive ridley populations showed thai the Australian breeding population at the McCluer Group of islands, Northern Territory, is genetically distinct from other olive ridley populations breeding in the Indo-Pacific. Howevei, nothing is known about the genetic stock structure among Australian olive ridley rookeries found across northern Australia. High predation of eggs by feral pigs, dogs and monitor lizards Varanus spp is believed to have severely imparted the number of nesting females at some rookeries. Of particular concern is the small nesting population on the western Cape York Peninsula, and without immediate conservation action this population could face extinction. The results presented here establish that there are at leiist 2 independent management units (stocks) of olive ridley turtles nesting in Australia and emphasise the importance of conserving the genetically distinct small breeding population nesting along the western Cape York Peninsula. In addition, results from 44 turtles caught in ghost nets across the Gulf of Carpentaria revealed that 45% of the haplotypes (32% of all ghost net samples) had not been observed at any rookery in Australia or SE Asia. This research highlights the need for better information on olive ridley population structure in the region and for urgent conservation action for the western Cape York population.

Members of the National Sea Turtle Stranding and Salvage Network responded, documenting the location and physical condition of each turtle. This report describes an ocean physical model-based analysis of the spring and summer 2011 Mississippi stranding events. Included within this group of strandings was 1 satellite-tagged moribund Kemp's ridley turtle, initially alive and tagged by the Institute for Marine Mammal Studies for a site fidelity study. Data from this tracking event provided an accurate time sequence of 58 h, during which the animal was presumed to be drifting, based on observed characteristics that were typical of a floating carcass. Turtle drift data were combined with output from the America SEAS (AMSEAS) hydrodynarnic: model to provide an estimate of leeway. The AMSGAS model was then applied to an additional 247 stranded turtles to produce 5 d Lagrangian backtrack drifts to derive mortality source location probability maps. Based on the model presented in this study, the majority ol mortalities appeared to have occurred in eastern Louisiana state waters.

Isotopic dilution mass spectrometry (IDMS) is becoming the methodology of choice to address these issues because the different isotopes of an element represent near-perfect internal standards. In this work, we investigated the lithium borate fusion of powdered solid samples, including soils, sediments, rock mine waste and a meteorite, as a strategy to homogenously distribute, i.e. equilibrate the elements and the added isotopically enriched standards. A comparison of this methodology using two pulsed laser ablation systems (ArF( upsilon .) excimer and Nd:YAG) with different wavelengths as well as two ICP-MS instruments (quadrupole and double-focusing sector field) was performed. Emphasis was put on using standard equipment to show the potential of the proposed strategy for its application in routine laboratories. Cr, Zn, Ba, Sr and Pb were successfully determined by LA-ICP-IDMS in six Standard Reference Materials (SRMs) representing different matrices of environmental interest. Experimental results showed the SRM fused glasses exhibited a low level of heterogeneity (intra- and inter-sample) for both natural abundance and isotopically enriched samples (RSD <3%, n = 3, 1a). A good agreement between experimental results and the certified values was also observed.

ER - TY - JOUR T1 - Testing systemic fishing responses with ecosystem indicators AN - 1676346767; PQ0001403655 AB - Successful implementation of Ecosystem Based Fisheries Management (EBFM) requires practical methods of translating information on system status into management actions. Threshold values in ecosystem indicators have been demonstrated to provide insight for characterizing change points in marine ecosystems and suggested as reference points for EBFM. We used a guild based multispecies simulation model of the Georges Bank finfish community to quantify tradeoffs and changes among values for proposed ecological indicators given alternative fishing scenarios, and tested the performance of indicator-based approaches for setting system ceilings on annual catches. Values for ecosystem indicators were sensitive to the exploitation rates on guilds, with total biomass of the community being most sensitive to groundfish exploitation rate. Setting ceilings on system-wide annual catches was successful in constraining values for indicators and revealed levels of system catch associated with indicator change. Community composition indicators showed catch thresholds lower than provided by the total biomass indicator. Ceilings based on community composition indicators more frequently resulted in higher yields and fewer species being overfished than when ceilings were set using total biomass or when no ceiling was in place. Simulations demonstrated that threshold values in ecosystem indicators could be used to determine reference points in an EBFM context. The broad ranges for threshold values obtained demonstrates the sensitivity of such methods to exploitation history, underscoring the need to both incorporate expert knowledge and relate reference point determination to management objectives.

At seasonal and intraseasonal time scales, polar motions are dominated by angular momentum fluctuations due to mass redistributions and relative motions in the atmosphere, oceans, and continental water, snow, and ice. In this study, we compare the geophysical excitations derived from various global atmospheric, oceanic, and hydrological models (NCEP, ECCO, ERA40, ERAinterim, and ECMWF operational products), and construct two model sets LDC1 and LDC2 by combining the above models with a least difference method. Comparisons between the geodetic excitation (derived from the polar motion series IERS EOP 08 C04) and the geophysical excitations (based on those meteorological models) imply that the atmospheric models are the most reliable while the hydrological ones are the most inaccurate; that the ERAinterim is, in general, the best model set among the original ones, but the combined models LDC1 and LDC2 are much better than ERAinterim; and that applying the frequency-dependent transfer functions to LDC1 and LDC2 improves their agreements with the geodetic excitation. Thus, we conclude that the combined models LDC1 and LDC2 are reliable, and the frequency-dependent Love numbers and polar motion transfer functions are well modeled. Abstract Copyright (2013), .

First, we present a power law for mantle anelasticity constrained by the Chandler period T (sub CW) and quality factor Q (sub CW) and an empirical quasi-fluid rheology model with a linear dependence on frequency, which is suitable for a period as long as approximately 18.6 years. Then we adopt the diurnal ocean tides from the International Earth Rotation and Reference Systems Service Conventions (2010), the long-period ocean model of Dickman and Gross (2010), and the equilibrium ocean pole tide model of Desai (2002) to calculate the oceanic corrections to the Love numbers. Further, we present discussions on the geophysical and observational aspects of the Chandler period TCW and quality factor Q (sub CW) , and provide preferred values and intervals for T (sub CW) and Q (sub CW) , which allow us to place some constraints on the mantle anelasticity and core-mantle coupling ratio eta (sub CW) . Although eta (sub CW) is affected by uncertainties in T (sub CW) and Q (sub CW) , we find its real part should be around 2%-3% while its imaginary part might be only a few thousandths. Finally, the frequency-dependent polar motion transfer functions T (super L) and T (super NL) are determined based on the models of frequency-dependent Love numbers and core-mantle coupling discussed above. Our transfer functions are related to the values of T (sub CW) and Q (sub CW) , however, our analyses demonstrate that our transfer functions are rather stable and not sensitive to perturbations in T (sub CW) and Q (sub CW) .

In this context, understanding the current state of climate engineering research can help inform policy discussions and guide future research directions. Bibliometric analysis-the quantitative analysis of publications-is particularly applicable to fields with large bodies of literature that are difficult to summarize by traditional review methods. The multidisciplinary nature of the published literature on climate engineering makes it an ideal candidate for bibliometric analysis. Publications on climate engineering are found to be relatively recent (more than half of all articles during 1988-2011 were published since 2008), include a higher than average percentage of nonresearch articles (30% compared with 8-15% in related scientific disciplines), and be predominately produced by countries located in the Northern Hemisphere and speaking English. The majority of this literature focuses on land-based methods of carbon sequestration, ocean iron fertilization, and solar radiation management and is produced with little collaboration among research groups. This study provides a summary of existing publications on climate engineering, a perspective on the scientific underpinnings of the global dialogue on climate engineering, and a baseline for quantitatively monitoring the development of climate engineering research in the future.

The impact of light bias and temperature over a broad excitation frequency range were measured. The observed features of the data, including a photocurrent 'phase-lead' and a 'phase-lag' over different regions of the frequency spectrum, were explored in the context of an equivalent circuit model. Comparisons between the model's predicted performance and the measured data suggest that charge carrier recombination at the cell's back metal/semiconductor contact is the main source of photocurrent loss in these devices.

BEA is now preparing to produce quarterly GDP by state statistics regularly. The quarterly GDP by state statistics are designed to be used in conjunction with other macroeconomic and regional data produced by BEA. This 'BEA Briefing' provides a first look at the most recent experimental quarterly GDP by state statistics, providing an overview of the methodology and discussing the initial results. It also discusses BEA's long-term plans to continue, develop, and improve these statistics. BEA plans to update potential users on the development of these statistics. The aim is to solicit feedback on how the current methodology might be improved before the new statistics become an official product of the Bureau. Adapted from the source document.

If the distribution generating the noise variables has low to moderate variance, then noise-multiplied data have been shown to yield accurate inferences in several typical parametric models under a formal likelihood-based analysis. However, the likelihood-based analysis is generally complicated due to the nonstandard and often complex nature of the distribution of the noise-perturbed sample even when the parent distribution is simple. This complexity places a burden on data users who must either develop the required statistical methods or implement the methods if already available or have access to specialized software perhaps yet to be developed. In this article we propose an alternate analysis of noise-multiplied data based on multiple imputation. Some advantages of this approach are that (1) the data user can analyze the released data as if it were never perturbed, and (2) the distribution of the noise variables does not need to be disclosed to the data user.

Entry costs faced by potential entrants, fixed costs faced by incumbent producers, and the toughness of short-run price competition are important determinants of long-run firm values, firm turnover, and market structure. In the dentist industry entry costs were subsidized in geographic markets designated as Health Professional Shortage Areas (HPSA) and the estimated mean entry cost is 11 percent lower in these markets. Using simulations, we find that entry cost subsidies are less expensive per additional firm than fixed cost subsidies.

In addition, tsunami waves triggered by the earthquake caused at least three fatalities at Petit Paradis due to a complete lack of tsunami awareness. The International Tsunami Survey Team (ITST) was deployed within weeks of the event and covered the greater Bay of Port-au-Prince and more than 100 km of Hispaniola's southern coastline.

Often the consequence of the political principal-agent problem is political catering to special interests. In this paper I provide examples of principal-agent problems regarding public spending. The examples concern construction or extension of concert halls in two German cities. Resistance to public funding for the concert halls was particularly strong in electoral districts with large constituencies on the left. The evidence indicates that political representatives were more bourgeois than their constituencies. In the cases studied asymmetric information did not prevail and voters were able to discipline their representatives through referenda that countered the results of voting by political representatives.

We compare the ESA and SARA, focusing on the roles of science and policy in determining which species warrant legal protection. Our analysis suggests that each act could benefit from mimicking the strengths of the other, and both could be strengthened by greater clarity and transparency of listing determinations. A particular strength of SARA is that all evaluations of species' status are conducted by a single national scientific body. The ESA does not involve a comparable national body but has more stringent legal deadlines for listing actions, and listing decisions cannot by law consider socioeconomic factors (as can occur under SARA). The conservation of biodiversity would be enhanced if both acts were complemented by additional programs focused on broader efforts that protect more species before individual intervention is needed.

Estimation and differentiation of such trends may be important for management, and a driving force for monitoring programs. The ability to estimate spatial differences in population trend may depend on assumptions regarding connectivity among subpopulations (stock structure or spatial overlap in stressors), information that is often poorly known. Linear state-space models using the Kalman filter were developed, tested, and applied for trend estimation of pup production for the western Alaska stock of Steller sea lions (Eumetopias jubatus), given only count data. Models were able to estimate trends and abundance even when data were missing. Models that assumed spatial correlation in trend among rookeries were more robust to stock structure assumptions when the stock structure was potentially mis-specified. High levels of spatial correlation among rookeries estimated from Steller sea lion pup count data are consistent with large-scale covariance of population trend within the Steller sea lion metapopulation.

Scaridae) AN - 1443375329; 18667012 AB - Some major anthropogenic stressors have impacts that occur at infrequent, unpredictable intervals; their effects are difficult to evaluate in a timely manner unless space is substituted for time. In this paper we substitute space for time along an environmental gradient that aliases a predicted temporal response to habitat restoration. We herein describe a 3-year study that combined field experiments and descriptive surveys of a fringing reef at Pelekane Bay, west Hawaii, along a sedimentation gradient from an intermittent stream that episodically discharges from the Kohala Watershed. This degraded watershed is now being restored by grazer exclusion, habitat engineering, and replanting of native flora. Sediment traps, arrays of settling plates, marked branches of endemic finger coral Porites compressa, together with surveys of benthic composition, densities of recruits of economically important parrotfishes, and the relative use of corals by fish recruits, were evaluated during the summers of 2010-2012. As expected, sediment accumulation rate decreased while all coral metrics and the densities, use, and preference of corals by recruit fishes generally increased with distance from the point of sediment discharge. Proportionate abundances of recruit through large adult-sized parrotfishes, overlayed on distributions (mapped by separate study) of sediment impact, allowed us to estimate, as an example, the amount and value of parrotfish rersources that are being unrealized because of sediment impacts on recruit parrotfish. Our Pelekane Bay case study thus illustrates how "space-for-time" substitution can be efficiently applied in an evaluation of potential watershed reclamation of reef resources-at a time considerably prior to likely temporal responses of the reef and its resources to watershed restoration.

AN - 1443369452; 18647786 AB - Although chemical preservation of stable isotope samples has been studied in a variety of species and tissue types, the effects of ethanol preservation on fish fin tissue have not been examined. Using caudal fin samples from juvenile Chinook Salmon Oncorhynchus tshawytscha and Rainbow Trout O. mykiss or steelhead (the anadromous form of Rainbow Trout), we investigated how storage time (2, 4, and 6 months), fin composition (C:N ratio), and fish body size (50-130 mm FL) influence preservation-induced changes in delta super(13)C and delta super(15)N. In both species, we found that treatment fins (frozen and later preserved in ethanol) exhibited higher delta super(13)C than did paired reference fins (frozen). The changes in delta super(15)N, however, were smaller in magnitude and less consistent. Preservation-induced increases in fin delta super(13)C, but not delta super(15)N, were significantly correlated with the change in C:N ratio (treatment-reference) in both species. In addition, these increases in delta super(13)C were more highly correlated with body size in O. mykiss than in Chinook Salmon. Storage time had a significant effect on the shift in treatment fin delta super(13)C and a small, but insignificant, effect on delta super(15)N in O. mykiss. However, storage time was not a significant factor for explaining the isotopic shifts observed in Chinook Salmon fin tissue. This is the first study to document variation in preservation-induced changes in delta super(13)C within a species and to link this variation to C:N ratio. Future studies using species-specific and tissue-specific models to correct for preservation-induced shifts in stable isotope ratios should be aware that these models do not account for intraspecific variation in tissue composition.

In this article, we aimed to verify the consistency of morphological characters in calcarean sponges of the well-known non-monophyletic order Clathrinida using a molecular phylogeny. For this we included 50 species, including six type species, currently assigned to eight different genera. A maximum likelihood topology was generated for the nuclear ITS marker using the General Time Reversible model and the bootstrap reliability test. Our topology indicated 10 clathrinid clades that included species with consistent morphological characters. In the present study, we defined nine of these clades as clathrinid genera, including four newly described and two newly diagnosed genera. Recent studies have indicated that not much phylogenetic information may be found in morphology, but our findings contradict this general assertion. Our study confirms the suitability of skeleton and body anastomosis as valid characters in a phylogenetically sound taxonomy for the order. Interestingly, we have also found that, apart from the Calcinea/Calcaronea split and a few minor details, Haeckel's original proposal is remarkably similar to our own, which was based on a molecular phylogeny 140 years later.

A cladistic analysis of morphology supported the monophyly of Cladorhizidae (including Euchelipluma), Guitarridae (excluding Euchelipluma), Isodictyidae, Latrunculiidae, and Podospongiidae but rejected monophyly for Desmacellidae, Esperiopsidae, Hamacanthidae, and Mycalidae. Analyses of partial 16S and partial 28S rRNA datasets combined, as well as that of a complete 18S rDNA dataset, suggest that Mycalina is not monophyletic; Biemnidae is only distantly related to other poecilosclerids; Merlia and Desmacella branch near the base of a diverse Poecilosclerida clade; Mycalidae is monophyletic (excluding Mycale [Anomomycale] titubans in 18S); and Esperiopsidae and Isodictyidae form a clade. Analyses of the two molecular datasets differed on the monophyly of Podospongiidae and about the relationship of Podospongiidae to Isodictyidae + Esperiopsidae.

Including age- or time-varying M in stock assessments, however, may not produce less biased parameter estimates, despite the increased realism. Two generic fish populations (long- and short-lived) subject to size- and year-varying M were simulated, along with data used to fit statistical catch-at-age (SCAA) models. The SCAA models assumed M was constant, age-varying, or year-varying, and the bias in estimates of spawning stock biomass (SSB), fully selected fishing mortality (F), and recruitment was recorded. The scale and trends among years in the bias of parameter estimates were generally driven by how the true values of M varied among years and how M was treated in the SCAA model. Bias was unaffected by how fishing mortality rates varied among years. The scale and trends among years in the bias of parameter estimates were generally similar when specifying a constant M and an age-varying M in the SCAA model. Using an annually varying M in the SCAA model generally improved the scale, and reduced trends among years in the bias of parameter estimates relative to constant M and age-varying M. Trends among years in bias were generally more pronounced for estimates of SSB than recruitment for long-lived life history simulations, but the opposite was true for short-lived life history simulations. These results suggested that the biases induced by not accounting for age-variation in M are likely secondary to those caused by the misspecification of temporal trends (trend and annual fluctuations in this case) in M. More time should be dedicated to accounting for temporal shifts in M than accounting for age-variation in M. The consequences of misspecification of M may also partially depend on life history.

Unfortunately, objective detection of convective vortices is often hindered by the strength and complexity of the flow in which they are embedded. To address this problem, a variational vortex-fitting algorithm previously developed to detect and characterize vortices observed by Doppler radar has been modified to operate on gridded horizontal wind data. The latter are fit to a simple analytical model of a vortex and its proximate environment, allowing the retrieval of important vortex characteristics. This permits the development of detection criteria tied directly to vortex properties (e.g., maximum tangential wind), rather than to more general kinematical properties that may poorly represent the vortex itself (e.g., vertical vorticity) when the background flow is strongly sheared. Thus, the vortex characteristic estimates provided by the technique may permit more effective detection criteria while providing useful information about vortex size, intensity, and trends therein. In tests with two simulated supercells, the technique proficiently detects and characterizes vortices, even in the presence of complex flow. Sensitivity tests suggest the algorithm would work well for a variety of vortex sizes without additional tuning. Possible applications of the technique include investigating relationships between mesocyclone and tornado characteristics, and detecting tornadoes, mesocyclones, and mesovortices in real-time ensemble forecasts.

The first group of samples inhabited open and cryptic habitats of shallow (15-20 m) Caribbean reefs at Bocas del Toro Archipelago, Panama. The second group inhabited schiophilous (e.g., inner coral framework and crevices) habitats on shallow reefs (0.5-20 m deep) in Moorea Island, French Polynesia. We applied an integrative approach by combining analyses of external morphology, histological observations, 18S rDNA, and mtCOI to determine the identity and the relationships of these unknown taxa within the order Verongida. Molecular analyses revealed that none of the species studied belonged to Hexadella (Ianthellidae, Verongida), the only fibreless genus of the Order Verongida currently recognized. The species from the Caribbean locality of Bocas del Toro (Panama) belong to the family Ianthellidae and is closely related to the Pacific genera Ianthella and Anomoianthella, both with well-developed fiber reticulations. We suggest the erection of a new generic denomination to include this novel eurypylous, fibreless ianthellid. The species collected in Moorea were all diplodal verongid taxa, with high affinities to a clade containing Pseudoceratina, Verongula, and Aiolochroia, a Pacific and two Caribbean genera, respectively. These unknown species represented at least three different taxa distinguished by DNA sequence analysis and morphological characteristics. Two new genera and a new species of Pseudoceratina are here proposed to accommodate these novel biological discoveries. The evolutionary and ecological meaning of having or lacking a fiber skeleton within Verongida is challenged under the evidence of the existence of fibreless genera within various verongid clades. Furthermore, the discovery of a fibreless Peudoceratina suggests that the possession of a spongin-chitin fiber reticulation is an "ecological" plastic trait that might be lost under certain conditions, such us growing within another organism's skeletal framework. These results raise new questions about the ecological and evolutionary significance of the development of a fiber skeleton and of sponges' adaptability to various environmental conditions.

The review addresses the following issues: (i) expected impacts on ecosystem productivity and habitat quantity and quality; (ii) impacts of changes in production and habitat on marine fish and shellfish species including effects on the community species composition, spatial distributions, interactions, and vital rates of fish and shellfish; (iii) impacts on fisheries and their associated communities; (iv) implications for food security and associated changes; and (v) uncertainty and modelling skill assessment. Climate change will impact fish and shellfish, their fisheries, and fishery-dependent communities through a complex suite of linked processes. Integrated interdisciplinary research teams are forming in many regions to project these complex responses. National and international marine research organizations serve a key role in the coordination and integration of research to accelerate the production of projections of the effects of climate change on marine ecosystems and to move towards a future where relative impacts by region could be compared on a hemispheric or global level. Eight research foci were identified that will improve the projections of climate impacts on fish, fisheries, and fishery-dependent communities.

The goal of this study was to determine whether cattle were a source of fecal pollution in a South Carolina watershed. Surface water samples were collected in June 2002 and February through March 2003 in closed shellfish harvesting waters of Toogoodoo Creek in Charleston County, SC. Fecal coliform concentrations in 70 % of the water samples taken for this study exceeded shellfish harvesting water standards. Ribotyping was performed in order to identify animal sources contributing to elevated fecal coliform levels. Escherichia coli isolates (n=253) from surface water samples were ribotyped and compared to a ribotype library developed from known sources of fecal material. Ribotypes from water samples that matched library ribotypes with 90 % maximum similarity or better were assigned to that source. Less than half of the unknown isolates (38 %) matched with library isolates. About half (53 %) of the matched ribotypes were assigned to cattle isolates and 43 % to raccoon. Ribotyping almost exclusively identified animal sources. While these results indicate that runoff from cattle farms was a likely source of fecal pollution in the watershed, wildlife also contributed. Given the small size of the library, ribotyping was moderately useful for determining the impact of adjacent cattle farms on Toogoodoo Creek. Increasing the number and diversity of the wildlife sources from the area would likely increase the usefulness of the method.

AN - 16395525; 15853 AB - PURPOSE: Expanded naval at-sea training and testing activities, including the use of active sonar and explosives, in the air and sea space around the Hawaiian Islands and off the coast of Southern California are proposed. The U.S. Navys Hawaii-Southern California Training and Testing (HSTT) study area consists of established operating and warning areas across the north-central Pacific Ocean, from Southern California west to Hawaii and the International Date Line. The study area combines the at-sea portions of the Hawaii Range Complex, the Southern California Range Complex, the Silver Strand Training Complex, a transit corridor on the high seas where training and sonar testing may occur during transit between the range complexes, and Navy pierside locations in San Diego Bay and Pearl Harbor where sonar maintenance and testing activities occur. This final overseas EIS consolidates three previous environmental analyses: the Hawaii Range Complex EIS, completed in 2008; the Southern California Range Complex EIS, completed in 2008; and the Silver Strand Training Complex EIS, completed in 2011. This reassessment will support reauthorization of permits under the Marine Mammal Protection Act and the Endangered Species Act. Three alternatives for HSTT are evaluated. Under the No Action Alternative, the Navy would continue current training and testing activities as defined by existing environmental planning documents. Alternative 1 would include the baseline activities of the No Action Alternative, plus adjustments to the study area boundaries and the location, type and level of training and testing activities as necessary to support current and planned requirements through 2019. Alternative 2 is the preferred alternative and would include new range capabilities, as well as modifications of existing capabilities, adjustments to type and tempo of training and testing, and the establishment of additional locations to conduct activities between the range complexes. Elements would include: new infrastructure requirements for the testing of autonomous vehicles near San Clemente Island; introduction of surface ships outfitted with railgun capability, and the testing of, and training with this new weapon system; introduction of broad area maritime surveillance unmanned aerial vehicles and their use during maritime patrol aircraft anti-submarine warfare testing and training events; a 10 percent increase in testing events, such as an increased number of unmanned/autonomous vehicle activities; and increased/accelerated delivery of surface ships necessitating increased number of ship trials and other post-delivery test and trial events. POSITIVE IMPACTS: Conducting realistic training and testing activities within the study area would ensure the Navy accomplishes its mission to maintain, train and equip combat-ready military forces capable of winning wars, deterring aggression and maintaining freedom of the seas. Expanded activities would accommodate changes in force structure requirements, the introduction of new weapons and platforms, and the training and testing required for proficiency with these systems. NEGATIVE IMPACTS: The proposed action could result in local changes in sediments and water quality as well as minor local emissions of air pollutants. Active sonar, explosions and other acoustic sources, physical disturbances and vessel strikes are likely to adversely affect individual marine mammals and sea turtles, but are not likely to adversely affect populations. In addition, sonar and other acoustic and energy sources may affect individual California steelhead trout, seabirds, and abalone.

AN - 16394295; 15854 AB - PURPOSE: Military training and testing activities which may include the use of active sonar and explosives, primarily within existing range complexes and testing ranges, along the east coast of the United States and the Gulf of Mexico are proposed. The U.S. Navys Atlantic Fleet Training and Testing (AFTT) study area covers approximately 2.6 million square nautical miles of ocean area, and includes designated operating areas and special use airspace. The following testing ranges and range complexes fall within the study area: Northeast Range Complexes; Naval Undersea Warfare Center Division, Newport Testing Range; Virginia Capes Range Complex; Navy Cherry Point Range Complex; Jacksonville Range Complex; South Florida Ocean Measurement Facility Testing Range; Undersea Warfare Training Range; Key West Range Complex; Naval Surface Warfare Center, Panama City Division Testing Range; and Gulf of Mexico Range Complex. Navy pierside locations and port transit channels where sonar maintenance and testing occur, and bays and civilian ports where training occurs are also included in the study area. This final overseas EIS consolidates previous environmental analyses and assesses three alternatives for AFTT. The assessment will support reauthorization of incidental takes of marine mammals under the Marine Mammal Protection Act and incidental takes of threatened and endangered marine species through consultation under Section 7 of the Endangered Species Act. The No Action Alternative would continue current and historic levels of activity based on previously completed Navy analysis. Alternative 1 reflects the adjustment to the baseline necessary to support all current and proposed Navy at-sea training and testing activities through 2019 and would expand the study area and adjust the types and levels of training and testing activities. Alternative 2 is the preferred alternative and would establish new range capabilities, modify existing capabilities, and further adjust the type and levels of training and testing. Elements would include: additional surface-to-air, surface-to-surface, and anti-submarine warfare activities; increased air combat maneuver events in the Key West Range Complex; training with surface ships outfitted with kinetic energy weapon capability; additional training with unmanned vehicles in support of mine warfare and of civilian port defense missions; new ship construction to include more sea trials for aircraft carriers, joint high speed vessels, and amphibious assault ships; more littoral combat ship mission package test events; increased post-homeporting testing; and more test events on each of the Naval Sea Systems Commands ranges and contingency for increased mine countermeasure testing at South Florida Ocean Measurement Facility Testing Range. POSITIVE IMPACTS: Military readiness training and testing activities would ensure that the Navy meets its mission, which is to maintain, train, and equip combat-ready naval forces capable of winning wars, deterring aggression, and maintaining freedom of the seas. NEGATIVE IMPACTS: The proposed action could impact marine habitats by localized disturbance of the seafloor, cratering of soft bottom sediments, and structural damage to hard bottom habitats. The use of explosives on or near the bottom, military expended materials, and seafloor devices may have an adverse effect on essential fish habitat. Acoustic and explosive stressors would impact individual marine mammals, but marine mammal populations would not be adversely affected. Explosive detonations and vessel strikes could disturb, injure, or kill marine mammals and sea turtles. Submerged prehistoric sites on the continental shelves in the Gulf of Mexico could be adversely affected.

Since 1842, 3446 people are reported to have perished to these killer waves. The tsunami generated by the 2010 Haiti earthquake claimed several lives, but the most recent devastating events were the 1946 tsunamis of the Dominican Republic, with at least 1800 victims (1). Since then, there has been an explosive increase in residents, visitors, infrastructure, and economic activity along Caribbean coastlines, increasing the potential for human and economic loss.

First, the comparison to a decade-long (2001-2010) daily rain gauge dataset reveals that: (1) 3B42V7 generally improves upon 3B42V6's underestimation both for the whole basin (bias from -41.15% to -8.38%) and for a 0.25 degrees X 0.25 degrees grid cell with high-density gauges (bias from -40.25% to 0.04%), though with modest enhancement of correlation coefficients (CC) (from 0.36 to 0.40 for basin-wide and from 0.37 to 0.41 for grid); and (2) 3B42V7 also improves its occurrence frequency across the rain intensity spectrum. Using the CREST model that has been calibrated with rain gauge inputs, the 3B42V6-based simulation shows limited hydrologic prediction NSCE skill (0.23 in daily scale and 0.25 in monthly scale) while 3B42V7 performs fairly well (0.66 in daily scale and 0.77 in monthly scale), a comparable skill score with the gauge rainfall simulations. After recalibrating the model with the respective TMPA data, significant improvements are observed for 3B42V6 across all categories, but not as much enhancement for the already-well-performing 3B42V7 except for a reduction in bias (from -26.98% to -4.81%). In summary, the latest 3B42V7 algorithm reveals a significant upgrade from 3B42V6 both in precipitation accuracy (i.e., correcting the underestimation) thus improving its potential hydrological utility. Forcing the model with 3B42V7 rainfall yields comparable skill scores with in situ gauges even without recalibration of the hydrological model by the satellite precipitation, a compensating approach often used but not favored by the hydrology community, particularly in ungauged basins.

Understanding of the dynamics that influence the spatio-temporal variability of total alkalinity (TA) - one major component of the seawater carbonate system - has been constrained by limited historical data collected across the shelf, and the consensus has been that TA is largely conservative. However, the recently documented undersaturated conditions have the potential to cause substantial non-conservative variability in TA in this region through the dissolution of carbonate minerals. In order to quantify the contribution of carbonate mineral precipitation and dissolution to variability in TA on the southeastern Bering Sea shelf, we examined seasonal observations of TA that were made between 2008 and 2010 as part of the BEST-BSIERP Bering Sea Project. Conservative influences accounted for most of the variability in TA concentrations, with well-constrained mixing dominating in spring and summer of 2008. Bering Shelf Water (BSW) contained a constant ratio of TA to salinity, while river discharge (RW) added TA relative to salinity at a predictable rate. Although substantial organic carbon production and denitrification can cause some non-conservative variation in TA concentrations (a maximum of nearly equal 15 mu molkgSW (super -1) combined), carbonate mineral dissolution and precipitation were shown to be the most important processes responsible for non-conservative TA-salinity relationships. CaCO (sub 3) uptake by the dominant pelagic phytoplankton calcifier (i.e., coccolithophores) was shown to alter TA concentrations by as much as 59 mu molkgSW (super -1) . Evidence for shallow-water CaCO (sub 3) mineral dissolution was also observed, which caused TA concentrations to increase by as much as 36 mu molkgSW (super -1) . Therefore, contrary to our previous understanding, the non-conservative physico-biogeochemical factors observed in this study play an important role in controlling the ocean carbon cycle of the Bering Sea shelf.

A better understanding of the geologic and hydrologic controls on these fluxes is critical for their estimation and management. We examined geologic features, porewater salinity, and SGD rates and patterns at an estuarine study site. Seismic data showed the existence of paleovalleys infilled with estuarine mud and peat that extend hundreds of meters offshore. A low-salinity groundwater plume beneath this low-permeability fill was mapped with continuous resistivity profiling. Extensive direct SGD measurements with seepage meters (n=551) showed fresh groundwater discharge patterns that correlated well with shallow porewater salinity and the hydrogeophysical framework. Small-scale variability in fresh and saline discharge indicates influence of meter-scale geologic heterogeneity, while site-scale discharge patterns are evidence of the influence of the paleovalley feature. Beneath the paleovalley fill, fresh groundwater flows offshore and mixes with saltwater before discharging along paleovalley flanks. On the adjacent drowned interfluve where low-permeability fill is absent, fresh groundwater discharge is focused at the shoreline. Shallow saltwater exchange was greatest across sandy sediments and where fresh SGD was low. The geologic control of groundwater flowpaths and discharge salinity demonstrated in this work are likely to affect geochemical reactions and the chemical loads delivered by SGD to coastal surface waters. Because similar processes are likely to exist in other estuaries where drowned paleovalleys commonly cross modern shorelines, the existence and implications of complex hydrogeology are important considerations for studies of groundwater fluxes and related management decisions.

AN - 16393391; 15838 AB - PURPOSE: The amendment of the Atlantic Mackerel, Squid, and Butterfish (MSB) Fishery Management Plan (FMP) to implement effective monitoring and to reduce incidental catch of river herrings (alewife and blueback herring) and shads (American shad and hickory shad) in ocean intercept fisheries in the New England-Middle Atlantic area is proposed. Stock assessments have identified that many populations of river herring along the Atlantic coast are in decline or are at depressed but stable levels; and blueback herring and alewife are both now considered candidate species under the Endangered Species Act. The 2007 American shad stock assessment found that stocks were at all-time lows and did not appear to be recovering. Key issues for Amendment 14 include the cost of conservation measures, concern about the impacts of large scale trawling on river herring and shad populations, and the lack of firm science about either the coast-wide populations of river herring and shad or about the impact on those populations from at-sea trawling versus other sources of mortality. About 80 alternatives are evaluated in this final EIS. These alternatives are grouped into eight sets, each including a No Action Alternative. The preferred alternatives recommended by the Mid-Atlantic Fishery Management Council would: require weekly vessel trip reports for all MSB permits; require a 48-hour pre-trip notification in order to retain, possess, or transfer more than 20,000 pounds of Atlantic mackerel; require vessel monitoring systems (VMS), as well as daily VMS catch reports, for limited access mackerel and longfin squid/butterfish moratorium permits to facilitate quota monitoring; and require a six-hour pre-landing notification via VMS for mackerel landings greater than 20,000 pounds. The preferred alternatives would also require federal MSB dealers to weigh all landings of mackerel over 20,000 pounds and longfin squid over 2,500 pounds or document why they cannot weight landings. Additional recommended measures would: increase observer coverage on limited access mackerel vessels using midwater and small-mesh bottom trawl, and require industry contributions of $325 per day; expand vessel requirements related to at-sea observer sampling; and establish measures to minimize the discarding of catch before it has been made available for sampling (slippage). The Council recommended 100 percent observer coverage of mid-water trawl mackerel trips as well as tiered coverage levels for small mesh bottom trawl mackerel trips. Coverage levels would be re-evaluated after two years. Since river herring/shad catch is greatest in the mackerel fishery, and current analysis suggested that area-based management could not be determined to be an effective measure, the Council recommended mortality caps for river herring/shad on the mackerel fishery and added future mortality caps and hotspot closures as frameworkable actions. Within six months of the completion of the Sustainable Fisheries Coalition river herring/shad avoidance project (expected late 2013), the Council will meet to formally review the results and consider the appropriateness of developing a framework adjustment to implement any additional catch avoidance strategies that are suggested by the results of the study. POSITIVE IMPACTS: The recommended alternatives are expected to have some incremental managed-resource benefits. To the extent that more frequent reporting and better data lead to more sustainable fisheries, implementation could allow additional landings and revenues. Alternatives that increase observer coverage are expected to have positive impacts for non-target species due to incidental catch and discarding concerns that would be alleviated by higher coverage rates. NEGATIVE IMPACTS: Commercial fishing interests would incur relatively low costs related to most of the alternatives being considered. Costs related to paying for vessel monitoring systems and observer coverage would be higher. Commercial dealers could incur moderate-to-higher additional costs for high volume scales to meet the weigh-all-fish requirements. Slippage restrictions could cause trip terminations resulting in lost revenue or potential safety issues if vessels bring catch aboard in dangerous conditions. Uncertainty about how the productivity of river herrings and shads is impacted by current incidental catch levels makes it difficult to quantity the impact of the recommended measures.

Here, we show that errors in the National Weather Service Colorado Basin River Forecast Center's operational streamflow predictions are correlated with the interannual variability of dust radiative forcing in snow. With data from 2000-2010, we show that errors in snowmelt period streamflow prediction for the southern Colorado Rockies are linearly related to melt period dust radiative forcing in snow as inferred from NASA Moderate Resolution Imaging Spectroradiometer data, which ranged interannually from 20 to 80 W m (super -2) . Each 10 W m (super -2) change of melt period dust forcing resulted in a corresponding change in runoff prediction bias of 10.0% + or - 1.5% and a 1.5 + or - 0.6 day shift in runoff center of mass. Accounting for bias introduced by dust forcing could improve streamflow prediction in regions prone to dust deposition in the snowpack. Abstract Copyright (2013), American Geophysical Union.

The resulting ensemble streamflow forecast provides an estimate of the predictive uncertainty associated with the single-valued forecast to support risk-based decision making by the forecasters and by the users of the forecast products, such as emergency managers. Forced by single-valued quantitative precipitation and temperature forecasts (QPF, QTF), the single-valued streamflow forecasts are produced at a 6-h time step nominally out to 5 days into the future. The single-valued streamflow forecasts reflect various run-time modifications, or "manual data assimilation", applied by the human forecasters in an attempt to reduce error from various sources in the end-to-end forecast process. The proposed procedure generates ensemble traces of streamflow from a parsimonious approximation of the conditional multivariate probability distribution of future streamflow given the single-valued streamflow forecast, QPF, and the most recent streamflow observation. For parameter estimation and evaluation, we used a multiyear archive of the single-valued river stage forecast produced operationally by the NWS Arkansas-Red River Basin River Forecast Center (ABRFC) in Tulsa, Oklahoma. As a by-product of parameter estimation, the procedure provides a categorical assessment of the effective lead time of the operational hydrologic forecasts for different QPF and forecast flow conditions. To evaluate the procedure, we carried out hindcasting experiments in dependent and cross-validation modes. The results indicate that the short-term streamflow ensemble hindcasts generated from the procedure are generally reliable within the effective lead time of the single-valued forecasts and well capture the skill of the single-valued forecasts. For smaller basins, however, the effective lead time is significantly reduced by short basin memory and reduced skill in the single-valued QPF. Abstract Copyright (2013) Elsevier, B.V.

AN - 16388726; 15830 AB - PURPOSE: The improvement of runway safety areas (RSAs) for two runways at the Kodiak Island Airport on Kodiak Island, Alaska is proposed. The Airport is situated along the shoreline of Womens Bay to the southwest and St. Paul Harbor to the northeast. Much of the submerged lands surrounding Kodiak Airport in Chiniak Bay are jointly managed by the U.S. Coast Guard Kodiak Station and the Alaska Maritime National Wildlife Refuge (NWR). The Buskin River and its estuary flow into the ocean directly north of the Airport. The U.S. Coast Guard owns the Kodiak Airport lands and facilities and leases these to the Alaska Department of Transportation and Public Facilities. The RSAs at the ends of runways 18/36 and 07/25 do not meet the Federal Aviation Administration (FAA) design standard for the aircraft commonly using these runways. The relocation or re-alignment of runways, reduction in runway length, and declared distances were determined to not be reasonable alternatives for improving the RSAs due to natural physical barriers and runway length requirements. The proposed project would involve placing fill into submerged lands that are a part of the Alaska Maritime NWR. Key issues include those related to natural resources and recreation near the Buskin River, cultural/traditional issues and subsistence, socioeconomics, and threatened, endangered, and sensitive species. This final EIS considers two action alternatives for runway 07/25 and six action alternatives for runway 18/36, as well as No Action alternatives for comparison. The preferred alternative for runway 07/25 (Alternative 2) would improve the RSA on the primary, east-west runway by placing fill into marine waters east of runway end 25. A 600-foot long RSA would be constructed and would include an engineered materials arresting system (EMAS) bed measuring 340 feet long by 170 feet wide. The preferred alternative for runway 18/36 (Alternative 7) would improve the RSAs on both ends of the north-south runway. At the north (runway end 18), no additional disturbance would occur beyond the current airport boundary, but an EMAS bed measuring about 155 feet long by 170 feet wide would be installed on the existing pavement. At the south (runway end 36), the runway would be shifted 240 feet further south, and a 360-foot RSA would be constructed. A combined 600 linear feet of new fill would extend beyond the existing runway threshold. Construction of the proposed project would occur over approximately two years. POSITIVE IMPACTS: The safety improvements would meet FAA standards to the extent practicable by the statutory deadline of December 31, 2015. The improvements would make Kodiak Airport safer for all passengers and pilots, and reduce the potential for damage to planes in the event of a runoff overshoot, undershoot, or veeroff. NEGATIVE IMPACTS: Construction would result in placement of 719,013 cubic yards of fill material into 24 acres of marine waters. Runway 07/25 Alternative 2 would change the substrate, gradient, and freshwater influence of existing habitats with major impacts to Buskin River salmonids. Fill placed off of runway end 36 into St. Paul Harbor would have an adverse effect on marine waters with concurrent direct loss of aquatic habitat and substrate. Five special-status waterbird species, northern sea otter, and Steller sea lion would be affected. Subsistence resources that are tied to the cultural practices of the local Alaska Native community may be significantly affected in the long-term and the decline in salmonid abundance would reduce the value of the Buskin River State Recreation Site in terms of sport fishing.

The NCSSC utilizes a collaborative business model to bring together stakeholders, including data producers and users, through a Core Management Team and advisory committee. The goal of the Cooperative is to leverage resources across organizations and integrate the multiple efforts within the NCSSC geography to provide better information to help stakeholders address the challenges associated with sea-level rise and coastal inundation. The Cooperative was formed to capitalize on and enhance the individual strengths of stakeholders to collectively address sea-level rise impacts within the coastal zone in a more holistic and efficient manner.

They exhibit high adsorption capacities for methane at 300 K and 35 bar (181-196 cm super(3) (STP) cm super(-3)). Supposing that the deliverable amount of methane is defined as the difference in the amount of methane adsorbed between 5 bar and 35 bar, NOTT-101a, NOTT-102a and NOTT-103a exhibit excellent deliverable capacities of methane (136-140 cm super(3) (STP) cm super(-3)), comparable to the highest of all previously reported MOF materials. The gravimetric methane uptake in this MOF series systematically increases with increasing porosity, while their methane storage pore occupancy decreases with increasing pore size. The fact that gravimetric methane uptakes correlate well with their corresponding pore volumes enables us to derive an empirical equation: C= -126.69 V sub(p) super(2) + 381.62 V sub(p) - 12.57, where Cis the excess gravimetric methane storage capacity at 35 bar and 300 K in cm super(3) (STP) g super(-1), and V sub(p) is the pore volume of a MOF material in cm super(3) g super(-1). This empirical equation can predict the methane storage performance of previously reported microporous MOF materials of V sub(p) less than 1.50 cm super(3) g super(-1) reasonably well, and thus provides a convenient method to screen MOFs for methane storage purposes.

Analysis of the Alabama free-air anomaly gravity data at crossover points at the three altitudes suggests 1-2 mgal accuracy for the dataset. Gravity data at each altitude are then expanded into local 3D Fourier series, to prepare for continuation. This Fourier representation results in continuation errors at few-mgal level in Alabama, even in the extreme case of downward continuation from 11 km to sea level. The result in Alabama inspires an airborne gravity survey over the rough, inaccessible terrain of Tibet. Similar investigations as in Alabama are made in Tibet using EGM08-derived airborne gravity data at flight altitudes of 10, 5, and 0 km. Bouguer anomalies at the 10-km altitude preserve the major tectonic features of Tibet. Downward continuation errors increase with terrain roughness, but the survey can enhance local tectonic features. This study highlights the value of a future Tibetan airborne gravity survey and points out the expected gravity accuracy and spatial resolution from this survey.

The NIPA estimates for 1929 through the first quarter of 2013 have been revised as part of the comprehensive NIPA revision. The acceleration in real GDP in the second quarter of 2013 primarily reflected upturns in nonresidential fixed investment and in exports, a smaller decrease in federal government spending, and an upturn in state and local government spending that were partly offset by an acceleration in imports and by decelerations in private inventory investment and in consumer spending. Prices of goods and services purchased by US residents increased 0.3% in the second quarter after increasing 1.2% in the first quarter. Real disposable personal income increased 3.4% in the second quarter after decreasing 8.2% in the first quarter. Adapted from the source document.

The material properties which control the mass loss, and are required for input to the numerical models, are measured in independent laboratory tests, and presented. The mass loss rate for each polymer is measured in the National Institute of Standards and Technology (NIST) gasification device and predicted using two numerical models for pyrolysis: the NIST Fire Dynamics Simulator (FDS) and the Federal Aviation Administration (FAA) model Thermakin. For three of the polymers, the models often gave results in very close agreement with each other, and in good agreement with those of the experiments for most of the mass loss period. Nonetheless, for PET, the agreement was good only in the initial stages of heating and mass loss, when less than 3% of the mass loss had occurred, and for POM, good agreement required a different value of the heat of reaction (from the one measured for this polymer). Parametric analyses are used to explore the influence of each measured parameter on the mass loss rate and the agreement between modeling and the experiments, and to explain discrepancies between the modeling and experiment when they exist.

Our research focuses on analyzing the changing distribution of employment in metropolitan areas by using tract-to-tract commuting data from Census 2000 to identify high-employment nodes within large metropolitan areas. We propose a new way to delineate clusters of contiguous high-employment tracts based on the job density in these areas. We then compare outlying employment clusters with traditional central business districts and contrast employment clusters of varying job densities. Our method has several advantages over existing methods of identifying employment clusters: it is conceptually simple, can use publicly available data, relies on a standardized geographic unit applicable across the entire United States, and offers the ability to examine data from multiple census years.

AN - 1448770042; 2011-516788 AB - Small Business Administration (SBA) loans have long been one of the most significant policy interventions in the U.S. affecting firm behavior, but little is known about their outcomes. This paper estimates the effects on employment using a list of all SBA loans linked to annual data on all U.S. employers from 1976 to 2010. Our methods combine firm fixed-effect regressions with matching on exact firm age, industry, year, and pre-loan size, and on propensity scores as a function of four years of employment history and other variables. The results imply positive average effects on loan recipient employment of about 25 percent, or 3 jobs at the mean. Including loan amount, we find little or no impact of loan receipt per se, but an increase of about 5.4 jobs for each million dollars of loans. Similar results for high-growth counties and industries suggest the estimates are not driven by differential demand conditions across firms. Exploiting variation in the distance of controls from recipient firms, we find only very small displacement effects. In all these cases, the results pass 'placebo' and "pre-program" specification tests. Other specifications using only matching or only regression imply somewhat higher effects, but they fail these tests. The estimates facilitate calculations of total job creation by the SBA and of the cost per job created. Tables, Figures, References.

Large shifts in the world distribution of Koppen-Geiger climate classifications by the end of this century have been projected. However, only a few studies have analysed the pace of these shifts in climate zones, and none has analysed whether the pace itself changes with increasing global mean temperature. In this study, pace refers to the rate at which climate zones change as a function of amount of global warming. Here we show that present climate projections suggest that the pace of shifting climate zones increases approximately linearly with increasing global temperature. Using the RCP8.5 emissions pathway, the pace nearly doubles by the end of this century and about 20% of all land area undergoes a change in its original climate. This implies that species will have increasingly less time to adapt to Koppen zone changes in the future, which is expected to increase the risk of extinction.

These cruises were conducted over large latitudinal (62 degrees N-60 degrees S) and longitudinal transects (11 degrees W-86 degrees W) in the Atlantic Ocean. Elevated seawater concentrations of CHBr (sub 3) and CH (sub 2) Br (sub 2) were often observed in regions where chlorophyll a concentrations were also elevated, which suggests biogeochemical processes associated with photosynthetic biomass may be related to CHBr (sub 3) and CH (sub 2) Br (sub 2) production. Our results suggest that, at least in the open ocean, several phytoplankton taxa may contribute to the production of these trace gases. While observed correlations between CHBr (sub 3) and CH (sub 2) Br (sub 2) in different regions are usually interpreted as common sources for these compounds, results in this study suggest different biogeochemical processes may contribute separately to the production of these trace gases. Heterotrophic bacterial abundance was significantly correlated with CH (sub 2) Br (sub 2) , but not with CHBr (sub 3) , which suggests the biogeochemical processes associated with heterotrophic bacteria may be related to CH (sub 2) Br (sub 2) in seawater but probably not to CHBr (sub 3) . In general, the Atlantic Ocean is a net source for CHBr (sub 3) and CH (sub 2) Br (sub 2) , except for a few locations where these trace gases were undersaturated in seawater. Assuming fluxes measured in the Atlantic open ocean are globally representative, the resulting extrapolated, global open-ocean annual net sea-to-air fluxes calculated from data from the five cruises was estimated at 0.24-3.80 Gmol Br yr (super -1) for CHBr (sub 3) and 0.11-0.77 Gmol Br yr (super -1) for CH (sub 2) Br (sub 2) .

We first characterize the considerable interannual variability in the size of the high chlorophyll region using SeaWiFS satellite data. We then evaluate the relationship between satellite chlorophyll and sea surface height (SSH), which are anticorrelated in the study region, most likely as a result of the inverse relationship between SSH and nutricline depth. To put these results in a longer temporal context, we study a hindcast simulation of a global ocean model with biogeochemistry (GFDL's MOM4.1 with TOPAZ biogeochemistry), after evaluating the model's skill at simulating chlorophyll and SSH relative to observations. In the simulation, the variability seen during the satellite era appears to be imbedded in a much larger multidecadal modulation. The drivers of such variability are assessed by evaluating all the terms in the nutrient budget of the euphotic zone. Because diffusive processes are not a dominant control on nutrient supply, stratification is not a good indicator of nutrient supply. Rather, vertical advection of nutrients, strongly tied to Ekman pumping, is the leading driver of variability in the size of the high chlorophyll region and the productivity within the study area.

A low-cost, large-area replica molding process is used to produce, on flexible plastic substrates, two-dimensional periodic arrays of cylinders that are subsequently coated with SiO sub(2) and Ag thin films to form dome-shaped structures, with 14 nm spacing between the features, in a precise and reproducible fashion. Three distinct optical resonance modes, a grating diffraction mode and two localized surface plasmon resonance (LSPR) modes, are observed experimentally and confirmed by finite-difference-time-domain (FDTD) modeling which is used to calculate the electromagnetic field distribution of each resonance around the nanodome array structure. Each optical mode is characterized by measuring sensitivity to bulk refractive index changes and to surface effects, which are examined using stacked polyelectrolyte layers. The utility of the plasmonic nanodome array as a functional interface for biosensing applications is demonstrated by performing a bioassay to measure the binding affinity constant between protein A and human immunoglobulin G (IgG) as a model system. The nanoreplica molding process presented in this work allows for simple, inexpensive, high-throughput fabrication of nanoscale plasmonic structures over a large surface area (120 120 mm super(2)) without the requirement for high resolution lithography or additional processes such as etching or liftoff. The availability of multiple resonant modes, each with different optical properties, allows the nanodome array surface to address a wide range of biosensing problems with various target analytes of different sizes and configurations.

However, this approach carries the risk of unwanted changes in the genetic characteristics of the target population and perhaps others that might incidentally be affected. We used genetic monitoring techniques to estimate the amount of introgression that has occurred from nonnative hatchery stocks into native populations and to determine the extent of genetic changes that have occurred in association with supplementation efforts over the past 20-50 years in Snake River Chinook Salmon O. tshawytscha populations from northeastern Oregon. A total of 4,178 fish from 13 populations were genotyped for 12 microsatellite DNA loci. Expected heterozygosity values for each sample ranged from 0.707 to 0.868. Estimates of the effective number of breeders per year in the naturally spawning populations ranged from 20.6 to 459.1, whereas in the hatchery populations they ranged from 33.8 to 1,118.8. We found that introgression from the Rapid River Hatchery stock was particularly noticeable in the early 1990s but that it appears to have had a substantial effect on only two of the native populations (Lookingglass Creek and the upper Grande Ronde River) despite the ample opportunities for introgression to occur. All seven of the native populations sampled have maintained their levels of within-population genetic diversity throughout the sampling period. Overall, this region's supplementation efforts appear to have had a minimal effect on the genetic diversity of its Chinook Salmon populations.

We derive asymptotic expressions for the mean square prediction error (MSPE) of both forecasts as N (cross sections) and T (time periods) grow large. Both the bias and variance of the least squares fitting are manifest in the MSPE. Using these expressions, we consider the effect of model specification on predictor accuracy. When the fitted lag order (q) is equal to or exceeds the true lag order (p), the direct MSPE is larger than the recursive MSPE. On the other hand, when the fitted lag order is underspecified, the direct MSPE is smaller than the recursive MSPE. The recursive MSPE is increasing in q for all q => p. In contrast, the direct MSPE is not monotonic in q within the permissible parameter space. Extensions to bias-corrected least squares estimators are considered.

It will understate changes in these costs when there are non-ad valorem trade costs and quality differences. Newly traded goods enter at higher trade costs than previously traded ones. Lower import costs shift trade to low-quality goods with higher measured trade costs. These effects are quantitatively important. U.S. import costs fall more than twice as fast as trade weighted measures from 1974 to 2004 after the impact of shifting quality and newly traded goods is accounted for. Empirical estimates that use trade weighting will underestimate the welfare impact of trade costs. // ABSTRACT IN FRENCH: Entrée sur le marché et coûts d'importation pondérés par les flux de commerce. La pondération par les flux de commerce est une méthode communément utilisée pour agréger les frictions commerciales. Cela tend à sous-estimer les changements dans ces coûts quand ils ne sont pas ad valorem et qu'il y a différences de qualité. Les biens nouvellement transigés ont des coûts plus élevés que ceux qui l'ont été plus tôt. Des coûts d'importation moins élevés déplacent le commerce vers des biens de moindre qualité mais avec des coûts de commerce mesurés plus élevés. Ces effets sont quantitativement importants. Les coûts d'importation des États-Unis ont chuté plus de deux fois plus vite que les mesures pondérées par les flux de commerce entre 1974 et 2004 une fois qu'on prend en compte l'impact sur la qualité et celui des biens nouvellement transigés. Les évaluations empiriques qui utilisent la pondération par les flux de commerce vont sous-estimer l'impact des coûts de commerce sur le bien-être.

The majority of OA exposure experiments use average atmospheric pCO sub(2) levels as a baseline treatment. We conducted an ecoregion-scale analysis of global carbon chemistry datasets. For many locales, atmospheric pCO sub(2) levels are not an appropriate characterization of marine carbon chemistry. We argue that atmospheric pCO sub(2) should be disregarded when setting baseline treatment conditions and experimental design should rely on measurements of carbon chemistry in a study subject's habitat. As carbon chemistry conditions vary with space and time, we suggest using a range of pCO sub(2) values as a control rather than a single value. We illustrate this issue with data on the habitat of Euphausia pacifica, which currently lives in waters with a pCO sub(2) around 900 mu atm, a concentration much higher than the current global atmospheric mean.

While widespread flooding did occur, its impacts were largely moderated through a combination of sustained cool weather during the melt season and mitigation measures based on forecasts. The potential for more severe flooding persisted from April through the first part of July as record-high snowpacks slowly melted. NOAA's Colorado Basin River Forecast Center (CBRFC) is the primary office responsible for generating river forecasts in support of emergency and water management within the Colorado River basin. This paper describes the 2011 runoff season in the basin and examines the skill of CBRFC forecasts for that season. The primary goal of this paper is to raise awareness of the research and development areas that could, if successfully integrated into the CBRFC river forecasting system, improve forecasts in similar situations in the future. The authors identify three areas of potential forecast improvement: 1) improving week two to seasonal weather and climate predictions, 2) incorporation of remotely sensed snow-covered area, and 3) improving coordination between reservoir operations and forecasts.

Several consistent changes were observed across all four realizations for the seasonal means: robust increase of U sub(10) and Hs in the Southern Ocean for both the austral summer and winter due to the poleward shift of the jet stream; a dipole pattern of the U sub(10) and Hs with increases in the northeast sector and decreases at the midlatitude during boreal winter in the North Atlantic due to the more frequent occurrence of the positive phases of the North Atlantic Oscillation (NAO); and strong decrease of U sub(10) and Hs in the tropical western Pacific Ocean during austral summer, which might be caused by the joint effect of the weakening of the Walker circulation and the large hurricane frequency decrease in the South Pacific. Changes of the 99th percentile U sub(10) and Hs are twice as strong as changes in the seasonal means, and the maximum changes are mainly dominated by the changes in hurricanes. Robust strong decreases of U sub(10) and Hs in the South Pacific are obtained because of the large hurricane frequency decrease, while the results in the Northern Hemisphere basins differ among the models. An additional sensitivity experiment suggests that the qualitative response of U sub(10) and Hs is not affected by using SST anomalies only and maintaining the radiative forcing unchanged (using 1980 values), as in this study.

BBH Ptype grids were compared to those derived by the standard National Weather Service (NWS) temperature threshold method. In this method, a fixed threshold temperature separating rain and snow was applied to hourly 4-km gridded temperature data. The BBH Ptype grids agreed well (>90%) with the temperature threshold-based grids below an elevation of 1524 m. The agreement dropped to below 60% above this elevation, and BBH Ptype produced more rainfall than the temperature-based Ptype. Continuous hourly streamflow simulations were generated using spatially lumped and distributed hydrologic models with and without the BBH Ptype data from 1 October 2005 through 30 September 2006. Simple insertion of BBH Ptype data did not always improve streamflow simulations for the 11 events examined relative to corresponding simulations using temperature threshold-derived precipitation type, possibly because of the use of the models calibrated with the temperature-based Ptype. The simple sensitivity test indicated simulations of both peak flows from midwinter storms and spring snowmelt runoff are affected by errors in precipitation type estimates.

The approach was evaluated over two watersheds in the Mackenzie River Basin in northwestern Canada as a contribution to the Canadian Global Energy and Water Cycle Experiment (GEWEX) study and the Mackenzie GEWEX Study (MAGS). Based on the sensitivity of the emitted microwave signal to soil roughness and vegetation parameters, a two-stage method was applied to calibrate a microwave radiative transfer model. Roughness parameters were determined using observations taken under dry conditions. Vegetation parameters were determined using observations taken under wet conditions. Obtained soil roughness and vegetation parameters were then integrated in the radiative transfer model to retrieve soil moisture. The performances of the proposed approach were evaluated against in situ observations, estimates from the NASA soil moisture product (AMSR-E), model-based soil moisture estimates from the NARR and gauge-based precipitation observations. The lowest RMSE of 0.0254 g/cm (super 3) was obtained between the retrieved soil moisture and in situ soil moisture. But, the RMSE between the NARR estimates and in situ soil moisture was 0.055 g/cm (super 3) and between the NASA AMSR-E product and in situ observation was 0.072 g/cm (super 3) . This implies that the proposed approach led to an improvement of 55% and 72% in the obtained RMSE over NARR and NASA AMSR-E soil moisture, respectively. It is noteworthy that the proposed approach is expandable to larger watersheds and very appropriate for remote regions like the Mackenzie River Basin where information on roughness and vegetation are scarce.

Free-air marine gravity anomalies derived from Geosat and ERS-1 satellite altimetry (Fairhead et al., 2001; Sandwell and Smith, 2009; Andersen et al., 2009) outline most of these major basins with remarkable precision. Moreover, gravity and bathymetry data derived from altimetry are used to identify current and paleo-submarine canyons, faults, and local recent uplifts. These geomorphic features provide clues to where to look for large deposits of sediments. While current altimeter data delineate large offshore basins and major structures, they do not resolve some of the smaller geomorphic features and basins (Yale et al., 1998; Fairhead et al., 2001). Improved accuracy and resolution is desirable: to facilitate comparisons between continental margins; as an exploration tool and to permit extrapolation of known structures from well-surveyed areas; to follow fracture zones out of the deep-ocean basin into antecedent continental structures, to define and compare segmentation of margins along strike and identify the position of the continent-ocean boundary; and to study mass anomalies (e.g., sediment type and distribution) and isostatic compensation at continental margins. In this article, we assess the accuracy of a new global marine gravity model based on a wealth of new radar altimetry data and demonstrate that these gravity data are superior in quality to the majority of publicly available academic and government ship gravity data.

Analyses using multidimensional scaling, and analysis of similarity revealed significant dietary differences among species, and similarity percentages tests helped identify the specific prey taxa responsible for these differences. Six species specialized on copepods (58.3-96.9% by number), but targeted different families. Specifically, the barbel flyingfish Exocoetus monocirrhus (n = 205) focused on euchaetids (51.6%), the banded flyingfish Hirundichthys marginatus (n = 24) fed on pontellids (21.8%), while the tropical two-wing flyingfish Exocoetus volitans (n = 11) and the bigwing halfbeak Oxyporhamphus micropterus (n = 34) ingested calanoids (54.6 and 17.0%). In contrast, the whitetip flyingfish Cheilopogon xenopterus (n = 73) and the mirrorwing flyingfish Hirundichthys speculiger (n = 4) had generalized diets comprising similar proportions of amphipod, copepod, mollusc and larval fish prey. Distinct differences in mean fullness, highly digested material, per cent empty guts and mean numbers of prey per gut were also synthesized, and uncovered a pattern of asynchronous feeding. Altogether, these findings provide valuable descriptive data on the diets of an understudied group of epipelagic teleosts, and, by extension, suggest that prey partitioning (taxa and feeding times) may influence flyingfish feeding ecology by reducing interspecific competition.

Between 2002 and 2004, a research program was initiated using chemical analysis in combination with bioanalytical techniques to assess the extent and variability in contamination at this dump site (DS). The data were compared to a reference area (RS) with similar environmental conditions, which is representative of the western Baltic Sea. Materials and methods: Twelve PAHs were investigated to assess their ecological hazard, as they were identified as major pollutants in the dumped material. In addition to analyzing the actual PAH contamination status in the sediments, PAHs measured in the soft tissue of Arctica islandica were also used as an indicator of contaminant bioaccumulation. A biotest battery was applied to determine the toxic effects of contaminants in the sediment. Results and discussion: Significantly elevated PAH concentrations (sum of 12 PAHs) of 3,000 ng g super(-1) dw and higher bioaccumulation factors (BAFs) were determined in the soft body tissue of A. islandica collected at DS (t test, p=0.025). The results also showed that the sediment PAH contamination was significantly higher at DS (1,952-5,466 ng g super(-1) dw) than at RS (1,384-2,315 ng g super(-1) dw). The results revealed a major heterogeneity in the PAH concentration at DS due to an attempt to cover the toxic material with clean clay. This resulted in a more heterogeneous distribution of the dump material rather than covering it up completely. However, not all relevant contaminants were included in this study, not only because it is too costly to determine them all but also because unidentified contaminants present at concentrations below the limit of detection cannot be measured. Bioassays were used to fill this gap in the hazard assessment in a cost-effective way by investigating the possible effects of sediment contamination on benthic organisms. The results showed a high variability and magnitude of growth and luminescence inhibition. Bacterial contact tests with marine organisms showed a high toxicity response (>80 % inhibition) from DS sediments. In contrast, the luminescent bacteria test (Vibrio fischeri) showed equivalent effects of sediments from both DS and RS. Conclusions: The spatial distribution of toxicity in DS, the bioaccumulation in mussels and the analytical evidence of PAH pollution clearly show that the dumped material still represents a potential risk even after 60 years.

Age-based demographic analyses were conducted at 10 locations in the main Hawaiian Islands and estimates of weight-at-length, size-at-age, and longevity were compared among locations. Each metric differed among locations, although patterns were not consistent across metrics. Length-weight relationships for C. argus differed among locations and individuals weighed less at a given length at Hilo, the southernmost location studied. Longevity differed among and within islands and was greater at locations on Maui and Hawaii compared to the more northern locations on Oahu and Kauai. Within-island growth patterns differed at Kauai, Oahu, and Hawaii. This work provides a case study of fundamental life history information from distant and/or spatially limited locations that are critical for developing robust fishery models. The differences observed both among and within islands indicate that variability may be driven by cross-scale mechanisms that need to be considered in fisheries stock assessments and ecosystem-based management.

AN - 1373442439; 23664766 AB - Spatial gradients of polychlorinated biphenyls (PCBs) and organochlorine pesticides were examined in the young-of-the-year (YOY) bluefish (Pomatomus saltatrix) in the vicinity of a PCB Superfund Site in New Bedford Harbor, Massachusetts, and in the adjacent waters. PCB concentrations in bluefish varied between different locations, and also among fish from a given location. A generally decreasing gradient in PCB concentrations was evident as the bluefish were collected away from the Superfund Site. The average sum of PCB concentrations were highest for bluefish collected in the Upper Harbor between Interstate-195 Bridge and Coggeshall Street Bridge (Upper Harbor), followed by bluefish in Lower Harbor from north of Popes Island Bridge (Lower Harbor), and bluefish from Outer Harbor south of Hurricane Barrier (Outer Harbor). The levels of PCBs in bluefish from Clarks Cove and PCBs in bluefish from Buzzards Bay were similar and lowest among all bluefish specimens analyzed in the present study. Pesticide concentrations were about one order of magnitude or lower than the PCB concentrations, and the gradient of pesticide concentrations generally followed the gradient of PCB concentrations. Some of the commonly detected pesticides in the order of decreasing concentrations included DDTs and metabolites, heptachlor epoxide, endosulfan sulfate, and α-chlordane. Distribution of PCBs and organochlorine pesticides were examined in the tissues of YOY bluefish from Clarks Cove. PCBs and lipids in the brain samples of YOY bluefish were generally numerically greater than PCBs in the liver samples, but these differences were not statistically significant. PCBs and lipids in hypaxial muscle samples were numerically greater than PCBs in epaxial muscle samples, although these two groups of tissues were not statistically different. Despite the higher susceptibility of lighter PCB homologs to geophysical and biogeochemical weathering processes, the relative dominance of lighter homologs in the Upper Harbor and Lower Harbor samples suggested ongoing or recent sources of these lighter PCBs, particularly Aroclor 1242 and Aroclor 1016 in this area. The presence of heavier homologs in the Upper Harbor and Lower Harbor bluefish samples could be attributed to Aroclor 1252 and Aroclor 1254 that were being used in relatively smaller quantities in the manufacture of electrical components in addition to Aroclor 1242 and Aroclor 1016. The concentration of heavier PCB homologs appears to increase in YOY bluefish the further away from the PCB Superfund Site in the Acushnet Estuary the samples were collected. Principal component analyses of PCB 153 normalized concentrations of the individual PCB congeners resulted in two general groupings; a relatively tight group comprised of YOY bluefish from Upper Harbor, Lower Harbor, and Outer Harbor, and a rather loose and more dispersed group comprised of Buzzards Bay bluefish and the tissue samples of bluefish from Clarks Cove. Principal component analyses of major pesticides suggested close groupings of bluefish from Clarks Cove and bluefish from Buzzards Bay. Pesticides in bluefish from Upper Harbor, Lower Harbor, and Outer Harbor formed a loose group, with some bluefish from these locations populating close to Clarks Cove and Buzzards Bay bluefish. Although PCBs have been implicated in various behavioral and health effects in the experimental and field studies, the deleterious effects of chronic exposure to high concentrations of PCBs and the potential for recruitment of New Bedford Harbor YOY bluefish population to the adult stock remains obscure. Adaptive or evolutionary resistance to contaminants have been documented in resident species in some highly contaminated estuaries, however similar responses have not been investigated in the migratory species like bluefish. The results of the present study provide a reference baseline for YOY bluefish for "before-and-after" comparative studies and other toxicological studies for the New Bedford Harbor Superfund Site that is currently being remediated.

Numerous hydrothermal vents in the crater of Kolumbo submarine volcano (Aegean Sea) are discharging virtually pure gaseous CO (sub 2) together with clear fluids at temperatures up to 220 degrees C. Acoustic imaging of the ascending bubbles suggests that the gas is being dissolved into seawater within approximately 10 m above the crater floor (500 m below sea level). Dissolution of the gas likely causes local increases in water density that result in sequestration of CO (sub 2) within the enclosed crater, and the accumulation of acidic seawater. Lack of macrofauna at the Kolumbo hydrothermal vents, occurrence of carbonate-poor sediment in the crater, and pH values as low as 5.0 in recovered water samples point to acidic conditions within the crater. Buildup of CO (sub 2) -rich water in the bowl-shaped crater of Kolumbo may be producing conditions analogous to some African volcanic lakes (Lake Monoun and Lake Nyos, Cameroon) where overturn of gas-rich bottom waters led to abrupt releases of CO (sub 2) at the surface. A minimum estimate of 2.0 X 10 (super 5) m (super 3) (STP) of excess CO (sub 2) may currently exist in the bottom 10 m of the Kolumbo crater.

AN - 1446869328; 15793 AB - PURPOSE: A restoration plan to address damage to natural resources, such as fish, shellfish, sediments, and water quality in the Lower Duwamish River (LDR), King County, Washington is proposed. The Elliott Bay Trustee Council is developing the LDR Natural Resource Damage Assessment (NRDA) to determine the extent of injuries to natural resources caused by releases of hazardous substances. Concurrently, the Trustees are conducting restoration planning to guide decision-making regarding restoration activities. The Duwamish River, once a meandering river with thousands of mudflats and wetlands, was channelized and narrowed through filling projects by the 1940's. The river flows through a highly industrial area and numerous facilities line its banks, including port facilities, manufacturing plants, chemical and solid waste recycling companies, ship repair yards, numerous combined sewer outfalls, and over 200 storm drains. Contaminants vary throughout the waterway, including polychlorinated biphenyls, polycyclic aromatic hydrocarbons, metals, phthalates, and dioxins/furans. Cleanup of the highly industrial LDR is being addressed through programs authorized by the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). Three alternatives, including a No Action Alternative (Alternative 1), are considered in this final programmatic EIS. Species-specific restoration (Alternative 2) would consist of planning and implementing individual NRDA restoration efforts to benefit specific species or small groups of species. Under this alternative, there would be more flexibility in locating restoration projects and the possible variety of projects would be greater. Integrated habitat restoration (Alternative 3) is the preferred alternative and would involve actions primarily to restore certain types of habitats that support a range of species. Typical restoration actions under this alternative would include removal of intertidal fill to restore mudflats, marsh, and/or riparian habitats, creation of off-channel areas, removal of creosote pilings and overwater structures that shade habitats, and softening shorelines. POSITIVE IMPACTS: The restoration of key estuarine and riparian habitats would benefit the range of resources injured by releases of hazardous substances in the LDR. Chinook salmon and Puget Sound steelhead would benefit from additional habitat. An improved ecosystem would support both natural resources and human use. The creation of more natural habitat along the river would enhance kayaking and boating recreation. NEGATIVE IMPACTS: Temporary impacts during construction would include: increased dust, noise and exhaust fumes; disturbance of soils and sediments; removal of vegetation for bank regrading; and increased turbidity. Restoration efforts would have uncertainty risks due to the highly-modified nature of the LDR shoreline and the variety of materials that have been used as fill.

AN - 1735921925; PQ0001785124 AB - Managing water resources generally and managing reservoir operations specifically have been touted as opportunities for applying forecasts to improve decision making. Previous studies have shown that the application of forecasts into water management is not pervasive. This study uses a scenario-based approach to explore whether and how people implement forecast information into reservoir operations decisions in a workshop setting. Although it was found that participants do utilize both forecast and observed information, they generally do not utilize probabilistic forecast information in a manner to appropriately minimize risks associated with the tail end of the forecast distribution. This study found strong tendencies for participants to wait for observed information, as opposed to forecast information, before making decisions. In addition, study participants tended to make decisions based on median forecast values instead of considering forecast probability. These findings support the development of quantitative decision support systems to optimally utilize probabilistic forecasts as well as for forecast agencies such as NOAA/NWS to continue investments in work to better understand contexts and environments where forecasts are used or have the potential for use in supporting water management decisions.

To accelerate research in these areas, we developed a microfluidic cytometer that measures forward light scatter, chlorophyll fluorescence induction and lipophilic stain fluorescence at a rate of 100 cells s super(-1). The chlorophyll fluorescence data is processed in real-time to measure the fluorescence-based maximum quantum yield, reported as F sub(v)/F sub(m), to quantify the photochemical energy conversion of each cell. To demonstrate instrument performance, F sub(v)/F sub(m) measurements are obtained for unstressed (nutrient-replete) and stressed (nutrient-limited) cultures of the marine diatom Phaeodactylum tricornutumand are correlated to values obtained in bulk samples using traditional pulse-amplitude-modulating fluorometry. We then use the cytometer to characterize unstressed and stressed P. tricornutumand show that lipid content (as measured by Nile Red fluorescence) is inversely correlated with F sub(v)/F sub(m). We believe these findings to be the first time that both photosynthetic efficiency and lipid accumulation have been simultaneously evaluated at the single cell level, and that in doing so, the diversity within these populations was revealed.

In the fourth quarter of 2012, real GDP rose 0.4%. The third estimate of real GDP growth was revised down 0.6% point from the second estimate. The revision reflected downward revisions to consumer spending, to exports, and to nonresidential fixed investment that were partly offset by a downward revision to imports. Consumer spending picked up in the first quarter, primarily reflecting a pickup in services. The largest contributor to the pickup in services was an upturn in electricity and gas. The downward revision to consumer spending was more than accounted for by a downward revision to spending for services. In services, the revisions were widespread; the largest contributors were "other" services, health care, and the gross output of nonprofit hospitals. Adapted from the source document.

Tomodachi means friendship in Japanese. This workshop, under the direction of Dr. Samuel L. Manzello of EL-NIST and Dr. Tokiyoshi Yamada of the University of Tokyo, was conducted in partnership with the Japan Association of Fire Science and Engineering (JAFSE). The objective was to: (1) develop scientific knowledge and translate it to building codes and standards that will be of use to both countries to reduce the devastation caused by unwanted fires, (2) provide a forum for next generation researchers to present their work in order to develop new research collaborations, (3) and allow USA participants a chance to visit excellent large-scale research facilities available in Japan that are of use to the research topics of this workshop. This is a formal continuation of the kickoff meeting held at NIST's Engineering Laboratory (EL-NIST) in June 2011. USA presentations were delivered from: NIST, Purdue University, University of Texas-Austin, Michigan State University, University of Michigan, Insurance Institute for Business and Home Safety (IBHS), Worcester Polytechnic Institute (WPI), University of California-Berkeley, California Polytechnic University (CALPOLY), Underwriters Laboratories (UL), and the University of Delaware (organizations are listed based on the order of oral presentation). Japanese presentations were delivered from: The University of Tokyo, Building Research Institute (BRI), Takenaka Corporation, Center for Better Living, Shimizu Corporation, Tokyo University of Science (TUS), National Institute for Land and Infrastructure Management (NILIM), Kyoto University, National Research Institute of Fire and Disaster (NRIFD), Yamagata University, and Kobe University (organizations are listed based on the order of oral presentation). All of the presentations are documented in a recent NIST Special Publication (NIST SP 1137). The present paper provides a detailed summary for the need of this workshop as well as the findings obtained from the event. It is desired that this activity will motivate the next generation of researchers to explore and develop research collaborations related to emerging areas of fire safety science. The authors are hopeful that new and exciting activities specific to other countries may come out of this type of event.

Our network-scale habitat models explained 27, 11, and 19% of the variation in density of juvenile Coho Salmon, age-0 steelhead, and steelhead parr, respectively, but strong levels of spatial autocorrelation were typically present in the residuals. Explanatory power of base habitat models increased and spatial autocorrelation decreased with the sequential inclusion of variables accounting for the effects of stream size, year, stream, reach location, and a tertiary interaction term. Stream-scale models were highly variable. Fish-habitat associations were rarely linear and ranged from negative to positive; the variable accounting for location of the habitat within a stream was often more important than the habitat variables. The limited success of our network-scale models was apparently related to variation in the strength and shape of fish-habitat associations across and within streams and years. These results indicate that there are several potential limitations to extrapolating models to broader areas based only on spatially limited surveys.

Using both actual data and simulations, we explored two approaches to the stock assessment of Georges Bank Atlantic sea scallops (Placopecten magellanicus), where fishery closures were implemented in December 1994. One approach modeled the stock in "aggregate", using domed commercial selectivity functions for the time periods when the MPAs were closed to scallop fishing. In the second "split" approach, separate models were used for the scallops inside (closed areas) and outside (open areas) the MPAs. The aggregate model converged only in 17% of the simulated runs, compared with 93% convergence for the open and closed runs using the split approach. With actual data, and in those simulations where both methods converged, the two approaches gave similar results, although biomass estimates in the most recent years from the aggregate model tended to be biased low. The closed area model, and to a lesser extent the aggregate model, estimated natural mortality M fairly precisely, but open area model estimates of M were poorly defined. Retrospective patterns were reduced using the split approach and when natural mortality was estimated. We conclude that the split assessment approach is better for sea scallops, but it may be best to use both approaches for comparative purposes.

In more recent decades, MPAs have been used by coastal and ocean managers to protect special areas for a wide range of purposes - protecting threatened or rare species, conserving areas for biological diversity and other ecological functions, setting aside areas for recreation - as well as a fisheries management tool. While the role of an MPA in protecting species or biological diversity is fairly well understood, their role as fisheries management tools is more complex and controversial. This paper provides an overview of the use of MPAs as a fisheries management tool in the United States, drawing on the comprehensive MPA Inventory developed and maintained by the National Marine Protected Areas Center (MPA Center).

Because such measurements are not routinely available, we developed predictive models of water-column (0-200 m) nitrate based on temperature for a region of the California Current System (30-47 degrees N) within 50 km from the coast. Prediction was done using generalized additive models based on a compilation of 37,607 observations collected over the period 1959-2004 and validated with a separate set of 6430 observations for the period 2005-2011. A temperature-only model had relatively high explanatory power (explained deviance, D (super 2) =71.6%) but contained important depth, latitudinal, and seasonal biases. A model incorporating salinity in addition to temperature (D (super 2) =91.2%) corrected for the latitudinal and depth biases but not the seasonal bias. The best model included oxygen, temperature, and salinity (D (super 2) =96.6%) and adequately predicted nitrate temporal behavior at two widely separated locations (44 degrees 39.1'N and 32 degrees 54.6'N) with slight or no bias [root-mean-square error (RMSE)=2.39 and 0.40 mu M, respectively). For situations when only temperature is available, a model including depth, month, and latitude as proxy covariates corrects some of the biases, but it had lower predictive skill (RMSE=2.50 and 5.22 mu M, respectively). The results of this study have applications for the proxy derivation of nitrate availability for primary producers (phytoplankton, macroalgae) in upwelling regions and for biogeochemical and ecosystem modeling studies.

However, analyses from photo-identification records often pose additional challenges. For example, it is often unclear how to link left- and right-side photos to the same individual, and previous studies have primarily used data from just one side for statistical inference. Here we describe how a recently developed statistical method can be adapted for integrated mark-recapture analyses using bilateral photo-identification records. The approach works by assuming that the true encounter history for each animal is a latent (unobserved) realization from a multinomial distribution. Based on the type of photo encounter (e.g., right, left, or both sides), the recorded (observed) encounter histories can only arise from certain combinations of these latent histories. In this manner, the approach properly accounts for uncertainty about the true number of distinct animals observed in the study. Using a Markov chain Monte Carlo sampling procedure, we conduct a small simulation study to show that this approach has reasonable properties and outperforms other methods. We further illustrate our approach by estimating population size from bobcat photo-identification records. Although motivated by bilateral photo-identification records, we note that the proposed methodology can be used to combine and jointly analyze other types of mark-recapture data (e.g., photo and DNA records).

When fish accumulate in a gear, the rate at which the gear catches fish can decline, and, as a result, catch asymptotes and q declines with longer fishing times. We used data from long-term trap surveys (1990-2011) in the southeastern U.S. Atlantic to determine whether traps saturated for 8 reef fish species because of the amount of time traps soaked or the level of fish accumulation (the total number of individuals of all fish species caught in a trap). We used a delta-generalized-additive model to relate the catch of each species to a variety of predictor variables to determine how catch was influenced by soak time and fish accumulation after accounting for variability in catch due to the other predictor variables in the model. We found evidence of trap saturation for all 8 reef fish species examined. Traps became saturated for most species across the range of soak times examined, but trap saturation occurred for 3 fish species because of fish accumulation levels in the trap. Our results indicate that, to infer relative abundance levels from catch data, future studies should standardize catch or catch rates with nonlinear regression models that incorporate soak time, fish accumulation, and any other predictor variable that may ultimately influence catch. Determination of the exact mechanisms that cause trap saturation is a critical need for accurate stock assessment, and our results indicate that these mechanisms may vary considerably among species.

PBR (Potential Biological Removal), developed under the U.S. Marine Mammal Protection Act (MMPA), is a limit for direct mortality for marine mammals, but it does not account for indirect effects of fishing due to prey depletion. I propose a generalization of PBR (called PBR*) to account for plausible changes in marine mammal carrying capacity ( Delta K) from prey biomass decline relative to two example benchmarks: SSBMSY (maximum sustainable yield biomass for all known prey species) or SSBK (unfished prey biomass). PBR* can help identify when indirect fishing effects (alone, or combination with direct mortality estimates) may stymie MMPA objectives, and could inform catch limit estimates for target species that are also important as marine mammal prey. As a case study, I applied PBR* estimates to evaluate the possible combined direct + indirect effects of fishing on cetaceans in northeastern U.S. waters. Estimated distributions for Delta K were based on fish stock assessments and meta-analysis of predator-prey relationships from the mammalian literature. Based on this analysis, increased risk of marine mammal depletion due to indirect fishing effects was not evident, although this result must be interpreted cautiously given our limited understanding of cetacean diets and marine trophic dynamics. This study is intended to illustrate a possible practical approach for incorporating indirect fisheries impacts on marine mammals into a comprehensive management framework, and it raises several scientific and policy issues that merit further investigation.

The success of this opportunity rests with the weather community's technical understanding and eventual adoption of these unique datasets and their level of participation in connected vehicle initiatives within the transportation community. All sectors of the weather enterprise (e.g., public, private, and academic) must become involved to help define, shape, and support the effort to realize a distinct and positive outcome on the weather and transportation communities. For this reason, the American Meteorological Society (AMS) Board on Enterprise Planning (BEP), under the Commission on the Weather and Climate Enterprise (CWCE), established an Annual Partnership Topic (APT) Committee in 2009 focused on mobile observations and their potential for use by the weather and transportation communities. The primary finding of the committee is that high-quality weather information about the roadway environment, including both current observations and forecasts, communicated in a timely and effective manner will help drivers make better and safer decisions regarding travel plans and react properly when faced with potentially compromised conditions; however, there are several technical, financial, societal, and institutional barriers that must be overcome before the full potential of mobile observations can be realized. This paper discusses several key issues important in advancing this concept, including potential benefits, barriers to acceptance, research needs, data quality and metadata, and business models.

Here the authors use observational and numerical modeling approaches to examine the influence of orography on the GSL-effect snowstorm of 27 October 2010, which generated 6-10 mm of precipitation (snow-water equivalent) in the Salt Lake Valley and up to 30 cm of snow in the Wasatch Mountains. The authors find that the primary orographic influences on the event are 1) foehnlike flow over the upstream orography that warms and dries the incipient low-level air mass and reduces precipitation coverage and intensity; 2) orographically forced convergence that extends downstream from the upstream orography, is enhanced by blocking windward of the Promontory Mountains, and affects the structure and evolution of the lake-effect precipitation band; and 3) blocking by the Wasatch and Oquirrh Mountains, which funnels the flow into the Salt Lake Valley, reinforces the thermally driven convergence generated by the GSL, and strongly enhances precipitation. The latter represents a synergistic interaction between lake and downstream orographic processes that is crucial for precipitation development, with a dramatic decrease in precipitation intensity and coverage evident in simulations in which either the lake or the orography are removed. These results help elucidate the spectrum of lake-orographic processes that contribute to lake-effect events and may be broadly applicable to other regions where lake effect precipitation occurs in proximity to complex terrain.

The simulations reproduce the well-known effects of updraft invigoration and delay of precipitation formation as increasing CCN from low to intermediate concentrations causes droplet sizes to decrease. Peak updrafts increased from 16 m s super(-1) at the lowest CCN to a maximum of 21-22 m s super(-1) at moderate CCN, where condensation latent heating is maximized. The transition from low to high CCN first maximizes warm-rain production before switching over to the ice process as the dominant precipitation mechanism. Average graupel density stays fairly high and constant at lower CCN, but then drops monotonically at higher CCN concentration, although high CCN also foster the appearance of small regions of larger, high-density graupel with high simulated radar reflectivity. Graupel production increases monotonically as CCN concentration rises from 50 to about 2000 cm super(-3). The lightning response is relatively weak until the Hallett-Mossop rime-splintering ice multiplication becomes more active at CCN > 700 cm super(-3). At very high CCN concentrations (>2000 cm super(-3)), graupel production decreases slowly, but lightning activity drops dramatically when the parameterization of Hallett-Mossop rime-splintering ice multiplication is based on the number of large cloud droplets collected by graupel. Conversely, lightning activity remains steady at extremely high CCN concentration when the Hallett-Mossop parameterization is based simply on the rate of rime mass accumulation. The results lend support to the aerosol hypothesis as applied to lightning production, whereby greater CCN concentration tends to lead to greater lightning activity, but with a large sensitivity to ice multiplication.

Previous studies have shown that African dust, transported westward from the Sahara and Sahel regions, can accumulate on mooring SWR sensors in the high-dust region of the North Atlantic (8 degree -25 degree N, 20 degree -50 degree W), potentially leading to significant negative SWR biases. Here dust-accumulation biases are quantified for each PIRATA mooring using direct measurements from the moorings, combined with satellite and reanalysis datasets and statistical models. The SWR records from five locations in the high-dust region (8 degree , 12 degree , and 15 degree N along 38 degree W; 12 degree and 21 degree N along 23 degree W) are found to contain monthly-mean accumulation biases as large as -200 W m super(-2) and record-length mean biases on the order of -10 W m super(-2). The other 12 moorings, located mainly between 10 degree S and 4 degree N, are in regions of lower atmospheric dust concentration and do not show statistically significant biases. Seasonal-to-interannual variability of the accumulation bias is found at all locations in the high-dust region. The moorings along 38 degree W also show decreasing trends in the bias magnitude since 1998 that are possibly related to a corresponding negative trend in atmospheric dust concentration. The dust-accumulation biases described here will be useful for interpreting SWR data from PIRATA moorings in the high-dust region. The biases are also potentially useful for quantifying dust deposition rates in the tropical North Atlantic, which at present are poorly constrained by satellite data and numerical models.

Acoustic recordings were collected from August 2008 to August 2010 at two locations and a single year (2008-2009) at a third location, in the western Beaufort Sea. Three recorders in 2008-2009 had a 30 % duty cycle and a bandwidth of 10-4,096 Hz. One recorder in 2009-2010 had a 45 % duty cycle and a bandwidth of 10-4,096 Hz and the second had a 20 % duty cycle and bandwidth of 10-8,192 Hz. Spectrograms of acoustic data were examined for characteristic patterns of bearded seal vocalizations. For each recorder, the number of hours per day with vocalizations was compared with in situ water temperature and satellite-derived daily sea ice concentrations. At all sites, bearded seals were vocally active year-round. Call activity escalated with the formation of pack ice in the winter and the peak occurred in the spring, coinciding with mating season and preceding breakup of the sea ice. There was a change in the timing of seasonal sea ice formation and retreat between the two consecutive years that was reflected in the timing of peak bearded seal call activity. This study provides new information on fall and winter bearded seal vocal behavior and the relationship between year-round vocal activity and changes in annual sea ice coverage and in situ water temperature.
