TY - RPRT T1 - EFFECTS OF OIL AND GAS ACTIVITIES IN THE ARCTIC OCEAN, BEAUFORT AND CHUKCHI SEAS, ALASKA. [Part 2 of 3] T2 - EFFECTS OF OIL AND GAS ACTIVITIES IN THE ARCTIC OCEAN, BEAUFORT AND CHUKCHI SEAS, ALASKA. AN - 963637274; 15192-6_0002 AB - PURPOSE: Management alternatives for the authorization of oil and gas exploration activities in the Beaufort and Chukchi seas within the five year period of 2012 through 2017 are proposed. The project area covers 200,331 square miles within the Alaskan portion of the Beaufort and Chukchi seas and includes State of Alaska and outer continental shelf waters adjacent to the North Slope of Alaska, and transit areas of the Chukchi Sea north of the Bering Straits. The statutory responsibilities include the issuance of permits and authorizations by the Bureau of Ocean Energy Management (BOEM) for seismic surveys and the issuance of incidental take authorizations (ITAs) by the National Marine Fisheries Service (NMFS). NMFS issues ITAs for oil and gas exploration activities because it is likely that seismic and exploratory drilling activities result in the disturbance of marine mammals. Key issues include: impacts to marine mammals and habitats; risks of oil spills; climate change; protection of subsistence resources and the Inupiat culture; availability of research and monitoring data for decision-making; monitoring requirements; and mitigation measures. Five alternatives, including a No Action Alternative (Alternative 1), are evaluated in this draft EIS. The reasonable range and level of activities for which permits and authorizations may be requested are based upon past lease sales, geological and geophysical permits, ancillary activity notices, exploration drilling exploration activities, and requests for ITAs. The activities that are evaluated in this EIS are grouped into three categories: deep penetration geophysical surveys including seismic surveys, gravity and gradiometry surveys, and controlled source electromagnetic (CSEM) surveys; shallow hazards surveys using acoustic imagery of the sub-seafloor or using sediment sampling devices; and exploratory drilling. Alternative 2 would authorize Level 1 activity to include: up to four seismic or CSEM surveys in the Beaufort Sea and up to three seismic or CSEM surveys in the Chukchi Sea per year, with up to one of that total number of surveys in each sea including ice breaking if necessary; up to three site clearance and high resolution shallow hazards survey programs in each sea per year; one on-ice seismic survey in the Beaufort Sea per year; and one exploratory drilling program in each sea per year. Alternative 3 would authorize Level 2 exploration activity to include: up to six seismic or CSEM surveys in the Beaufort Sea and up to five seismic or CSEM surveys in the Chukchi Sea per year, with up to one of that total number in each sea including ice breaking; up to five site clearance and high resolution shallow hazards survey programs in each sea per year; one on-ice seismic survey in the Beaufort Sea per year; and up to two exploratory drilling programs in each sea per year. Alternatives 4 and 5 would also authorize Level 2 exploration activity, but with additional required time/area closures and use of alternative technologies, respectively. POSITIVE IMPACTS: Implementation would facilitate NMFS decision-making through proactive analysis of the effects of multiple exploration activities and the effectiveness of mitigation measures. The collection of high-resolution shallow hazards data would help the BOEM ensure safe operations, support environmental impact analyses, protect resources through avoidance measures, and perform other statutory responsibilities. NEGATIVE IMPACTS: Seismic and exploratory drilling activities may result in the disturbance of marine mammals through sound, discharge of pollutants, and the physical presence of vessels. Drill sites would impact visual resources. A very large oil spill scenario would cause: sustained degradation of water quality and ecosystems; contamination of essential fish habitat; toxic exposure of marine and terrestrial species; contamination of the shoreline with major disruption of subsistence practices; displacement of recreationists and reduction in tourism; acute disturbance of visual resources; and impacts to public health.

[Part 2 of 2] T2 - HURRICANE AND STORM DAMAGE REDUCTION PROJECT, MID-REACH SEGMENT, BREVARD COUNTY, FLORIDA. AN - 963637272; 15188-2_0002 AB - PURPOSE: The restoration of a protective and recreational beach along 7.8 miles of shoreline known as the Mid-Reach in Brevard County, Florida is proposed. The project area is located on the east coast of Florida just south of Cape Canaveral and contains the municipalities of Satellite Beach, Indian Harbour Beach, and Melbourne and portions of unincorporated Brevard County. Beaches are in a state of severe erosion and shoreline recession. The Mid-Reach was previously studied as part of the Brevard County Shore Protection Project, but was removed from the recommended plan in the final EIS of 1996 due to concerns about impact to the nearshore hardbottom. The locally preferred plan (Local Option 6) is also the recommended plan in this final supplemental EIS. Local Option 6 would implement a small-scale dune and beach fill using beach-compatible sand from offshore borrow sources. The plan consists of a 10-foot extension of the mean high water line plus advanced nourishment to maintain that design fill volume in Reach 1, a 20-foot extension of the mean high water line plus advanced nourishment to maintain that design fill volume in Reaches 2 and 3, a 10-foot extension of the mean high water line plus advanced nourishment to maintain that design fill volume in Reaches 4 and 5, and a dune fill with no added advanced nourishment in Reach 6. The approximate volume of sand that would be placed includes an initial design fill of 445,000 cubic yards plus an advanced nourishment fill of 210,000 cubic yards for a total fill of 655,000 cubic yards at initial construction. Fill would be accomplished by rehabilitating the Poseidon dredged material management area (DMMA) at Port Canaveral, dredging material from Canaveral Shoals with placement into the Poseidon DMMA every six years, and hauling by dumptruck to the Mid-Reach for placement on the beach at three year intervals. Total cost of implementing the recommended plan over 50 years is estimated at $164.9 million. POSITIVE IMPACTS: The project would reduce damages caused by erosion and coastal storms, benefit recreational resources, and protect shoreline property. Erosion protection would vary along the length of the Mid-Reach from a 5-year storm level to a 75-year storm level. The project would yield an estimated $12.9 million annually through prevention of storm damage and incidental recreation benefits with a benefit-cost ratio of 3.1. NEGATIVE IMPACTS: Implementation would disturb biotic habitats in the sand borrow areas and along the littoral zone in the immediate area of beach renourishment. It is anticipated that placement of sand would impact 3.0 acres of nearshore rock hardbottom resulting in the loss of a biologically significant marine ecosystem.

POSITIVE IMPACTS: Implementation would facilitate NMFS decision-making through proactive analysis of the effects of multiple exploration activities and the effectiveness of mitigation measures. The collection of high-resolution shallow hazards data would help the BOEM ensure safe operations, support environmental impact analyses, protect resources through avoidance measures, and perform other statutory responsibilities. NEGATIVE IMPACTS: Seismic and exploratory drilling activities may result in the disturbance of marine mammals through sound, discharge of pollutants, and the physical presence of vessels. Drill sites would impact visual resources. A very large oil spill scenario would cause: sustained degradation of water quality and ecosystems; contamination of essential fish habitat; toxic exposure of marine and terrestrial species; contamination of the shoreline with major disruption of subsistence practices; displacement of recreationists and reduction in tourism; acute disturbance of visual resources; and impacts to public health.

AN - 16373662; 15188 AB - PURPOSE: The restoration of a protective and recreational beach along 7.8 miles of shoreline known as the Mid-Reach in Brevard County, Florida is proposed. The project area is located on the east coast of Florida just south of Cape Canaveral and contains the municipalities of Satellite Beach, Indian Harbour Beach, and Melbourne and portions of unincorporated Brevard County. Beaches are in a state of severe erosion and shoreline recession. The Mid-Reach was previously studied as part of the Brevard County Shore Protection Project, but was removed from the recommended plan in the final EIS of 1996 due to concerns about impact to the nearshore hardbottom. The locally preferred plan (Local Option 6) is also the recommended plan in this final supplemental EIS. Local Option 6 would implement a small-scale dune and beach fill using beach-compatible sand from offshore borrow sources. The plan consists of a 10-foot extension of the mean high water line plus advanced nourishment to maintain that design fill volume in Reach 1, a 20-foot extension of the mean high water line plus advanced nourishment to maintain that design fill volume in Reaches 2 and 3, a 10-foot extension of the mean high water line plus advanced nourishment to maintain that design fill volume in Reaches 4 and 5, and a dune fill with no added advanced nourishment in Reach 6. The approximate volume of sand that would be placed includes an initial design fill of 445,000 cubic yards plus an advanced nourishment fill of 210,000 cubic yards for a total fill of 655,000 cubic yards at initial construction. Fill would be accomplished by rehabilitating the Poseidon dredged material management area (DMMA) at Port Canaveral, dredging material from Canaveral Shoals with placement into the Poseidon DMMA every six years, and hauling by dumptruck to the Mid-Reach for placement on the beach at three year intervals. Total cost of implementing the recommended plan over 50 years is estimated at $164.9 million. POSITIVE IMPACTS: The project would reduce damages caused by erosion and coastal storms, benefit recreational resources, and protect shoreline property. Erosion protection would vary along the length of the Mid-Reach from a 5-year storm level to a 75-year storm level. The project would yield an estimated $12.9 million annually through prevention of storm damage and incidental recreation benefits with a benefit-cost ratio of 3.1. NEGATIVE IMPACTS: Implementation would disturb biotic habitats in the sand borrow areas and along the littoral zone in the immediate area of beach renourishment. It is anticipated that placement of sand would impact 3.0 acres of nearshore rock hardbottom resulting in the loss of a biologically significant marine ecosystem.

[Part 1 of 1] T2 - ILLINOIS COASTAL MANAGEMENT PROGRAM, COOK AND LAKE COUNTIES, ILLINOIS. AN - 963635625; 15180-4_0001 AB - PURPOSE: The approval of the Illinois Coastal Management Program (ICMP), which describes current state coastal legislation and management policies, is proposed. The ICMP is based on a framework and process for linking existing state programs, agencies, and laws into a system that will meet federal requirements under the Coastal Zone Management Act (CZMA) for an effective state coastal management program. It provides for the management of all land and water uses having a direct and significant impact on coastal waters. Policies are articulated for: public waters, navigation and the public interest; erosion and flooding; water quality and supply; habitats, wetlands, and wildlife; historic, archaeological and cultural resources; recreation and public access; economic development; and energy facilities and air quality. The ICMP would require the Illinois Department of Natural Resources to monitor all state actions which could affect coastal resources, resolve conflicts between state agency decisions and the provisions of the ICMP, and enhance implementation of core programs such as addressing erosion hazards, economically depressed waterfront areas, and planning for and creating public access. Examples of tasks that would be performed include program administration, federal consistency review, ICMP review and evaluation, networking with state and local agencies, outreach and education, and grant administration. Illinois uses a two-component inland boundary: the Lakeshore Boundary defines the landward limit of the coastal zone inland, and is generally parallel to the Lake Michigan shoreline; the Inland Waterway Boundary consists of a corridor that extends along the near-lake segments of the river systems that historically flowed to Lake Michigan but are now engineered to flow away from the lake. The inland waterway corridors consist of both the waterway, and designated land area to either side of the waterway, and include select segments of the Chicago River system and the Little and Grand Calumet Rivers. Three alternatives are considered in this final EIS. Under Alternative 1, the National Oceanic and Atmospheric Administrations Office of Ocean and Coastal Resource Management (OCRM) would approve the ICMP. Alternative 2 is the No Action Alternative and would deny approval of the ICMP. Under Alternative 3, OCRM could delay approval if any element of the ICMP does not meet requirements and requires some modification. The preliminary determination is that the proposed ICMP is consistent with the objectives and policies of the CZMA and that the award of federal funds will help meet those objectives. POSITIVE IMPACTS: Approval of the ICMP would qualify Illinois for federal matching of funds for use in administering the program. Implementation would enhance governance of coastal land and water uses and would strengthen local stakeholder capacity to initiate and continue effective coastal management consistent with identified state standards and criteria. NEGATIVE IMPACTS: With or without the ICMP, the intensely developed and populated Illinois coastal region would likely continue to be affected by additional development. Approval of the ICMP would commit funds and personnel to a program which must weigh diverse, often conflicting values, between resource protection and development. The denial or delay of approval of the ICMP would result in the loss of approximately $2 million in federal funds annually to administer the program and of the opportunity to ensure consistency of federal activities in or affecting its coastal areas.

[Part 15 of 18] T2 - SUISUN MARSH HABITAT MANAGEMENT, PRESERVATION, AND RESTORATION PLAN, SOLANO COUNTY, CALIFORNIA. AN - 928982152; 15175-9_0015 AB - PURPOSE: A comprehensive plan to address conflicts regarding use of resources within Suisun Marsh, Solano County, California is proposed. The Suisun Habitat Management, Preservation, and Restoration Plan is intended to balance the benefits of tidal wetland restoration with other habitat uses by evaluating alternatives that provide an acceptable change in land uses, such as salt marsh harvest mouse habitat, managed wetlands, public use, and upland habitat. Suisun Marsh is the largest contiguous brackish water marsh remaining on the west coast of North America and is a critical part of the San Francisco Bay/Sacramento-San Joaquin River Delta estuary ecosystem. It is home to public waterfowl hunting areas and 158 private duck clubs. The Marsh encompasses more than 10 percent of Californias remaining natural wetlands and provides important habitat for more than 221 bird species, 45 mammalian species, 16 different reptile and amphibian species, and more than 40 fish species. Approximately 200 miles of levees in the Marsh contribute to managing salinity in the Sacramento-San Joaquin River Delta. Large open spaces and proximity to urban areas make the Marsh ideally suited for wildlife viewing, hiking, canoeing, and other recreation opportunities. A group of local, state, and federal agencies with primary responsibility for management are pursuing the Suisun Marsh Plan (SMP), and this final EIS describes three alternative 30-year plans, as well as a No Action Plan. The total amount of existing managed wetlands and uplands that could be affected by SMP activities is 52,112 acres. Under Alternative A, which is the proposed project and preferred alternative, 5,000 to 7,000 acres would be restored to self-sustaining tidal wetland and the remaining 44,000 to 46,000 acres of managed wetlands would be enhanced for levee stability and flood and drain capabilities. Alternative B and Alternative C would restore 2,000 to 4,000 acres and 7,000 to 9,000 acres of tidal wetland, respectively. Land suitable for restoration would be acquired only from willing sellers. Activities would include: breaching or lowering existing levees; upgrading or constructing new levees; grading pond bottoms; installing or replacing pipe, drain pumps, and platforms; replacing riprap and water control structures; installing alternate bank protection; constructing cofferdams; installing new fish screens; repairing or replacing salinity monitoring stations; and dredging from tidal sloughs. Over the 30-year SMP implementation period, it is expected that the exact habitat amount provided by restored areas will depend on the existing elevation of the site, sedimentation rates and accretion, and sea level rise. The amount of subtidal aquatic habitat is expected to decrease gradually as sediment accretes and emergent tidal vegetation is established at each restoration site. As this happens, the site will be restored to a tidal wetland. POSITIVE IMPACTS: Development of a regional plan would balance implementation of the CALFED Program, the Suisun Marsh Preservation Agreement, and other management and restoration programs in a manner responsive to the concerns of stakeholders and based upon voluntary participation by private landowners. Under the preferred plan, 5,000 to 7,000 acres would be restored as tidal wetlands and tidal aquatic habitat would increase by 250 to 1,050 acres. Fish habitat would be improved due to increased oxygen concentrations in tidal channels and shorebird and waterfowl populations would benefit from improved nesting and winter habitat. The potential for catastrophic flooding would be reduced. NEGATIVE IMPACTS: Construction-related emissions would exceed draft local standards for restoration and management activities; and noise-sensitive land uses would be exposed to noise from portable pump operations. Construction and dredging could damage pipelines and disrupt electrical, gas, or other energy supplies.

AN - 928982133; 15175-9_0013 AB - PURPOSE: A comprehensive plan to address conflicts regarding use of resources within Suisun Marsh, Solano County, California is proposed. The Suisun Habitat Management, Preservation, and Restoration Plan is intended to balance the benefits of tidal wetland restoration with other habitat uses by evaluating alternatives that provide an acceptable change in land uses, such as salt marsh harvest mouse habitat, managed wetlands, public use, and upland habitat. Suisun Marsh is the largest contiguous brackish water marsh remaining on the west coast of North America and is a critical part of the San Francisco Bay/Sacramento-San Joaquin River Delta estuary ecosystem. It is home to public waterfowl hunting areas and 158 private duck clubs. The Marsh encompasses more than 10 percent of Californias remaining natural wetlands and provides important habitat for more than 221 bird species, 45 mammalian species, 16 different reptile and amphibian species, and more than 40 fish species. Approximately 200 miles of levees in the Marsh contribute to managing salinity in the Sacramento-San Joaquin River Delta. Large open spaces and proximity to urban areas make the Marsh ideally suited for wildlife viewing, hiking, canoeing, and other recreation opportunities. A group of local, state, and federal agencies with primary responsibility for management are pursuing the Suisun Marsh Plan (SMP), and this final EIS describes three alternative 30-year plans, as well as a No Action Plan. The total amount of existing managed wetlands and uplands that could be affected by SMP activities is 52,112 acres. Under Alternative A, which is the proposed project and preferred alternative, 5,000 to 7,000 acres would be restored to self-sustaining tidal wetland and the remaining 44,000 to 46,000 acres of managed wetlands would be enhanced for levee stability and flood and drain capabilities. Alternative B and Alternative C would restore 2,000 to 4,000 acres and 7,000 to 9,000 acres of tidal wetland, respectively. Land suitable for restoration would be acquired only from willing sellers. Activities would include: breaching or lowering existing levees; upgrading or constructing new levees; grading pond bottoms; installing or replacing pipe, drain pumps, and platforms; replacing riprap and water control structures; installing alternate bank protection; constructing cofferdams; installing new fish screens; repairing or replacing salinity monitoring stations; and dredging from tidal sloughs. Over the 30-year SMP implementation period, it is expected that the exact habitat amount provided by restored areas will depend on the existing elevation of the site, sedimentation rates and accretion, and sea level rise. The amount of subtidal aquatic habitat is expected to decrease gradually as sediment accretes and emergent tidal vegetation is established at each restoration site. As this happens, the site will be restored to a tidal wetland. POSITIVE IMPACTS: Development of a regional plan would balance implementation of the CALFED Program, the Suisun Marsh Preservation Agreement, and other management and restoration programs in a manner responsive to the concerns of stakeholders and based upon voluntary participation by private landowners. Under the preferred plan, 5,000 to 7,000 acres would be restored as tidal wetlands and tidal aquatic habitat would increase by 250 to 1,050 acres. Fish habitat would be improved due to increased oxygen concentrations in tidal channels and shorebird and waterfowl populations would benefit from improved nesting and winter habitat. The potential for catastrophic flooding would be reduced. NEGATIVE IMPACTS: Construction-related emissions would exceed draft local standards for restoration and management activities; and noise-sensitive land uses would be exposed to noise from portable pump operations. Construction and dredging could damage pipelines and disrupt electrical, gas, or other energy supplies.

Under the preferred plan, 5,000 to 7,000 acres would be restored as tidal wetlands and tidal aquatic habitat would increase by 250 to 1,050 acres. Fish habitat would be improved due to increased oxygen concentrations in tidal channels and shorebird and waterfowl populations would benefit from improved nesting and winter habitat. The potential for catastrophic flooding would be reduced. NEGATIVE IMPACTS: Construction-related emissions would exceed draft local standards for restoration and management activities; and noise-sensitive land uses would be exposed to noise from portable pump operations. Construction and dredging could damage pipelines and disrupt electrical, gas, or other energy supplies.

AN - 928982094; 15175-9_0008 AB - PURPOSE: A comprehensive plan to address conflicts regarding use of resources within Suisun Marsh, Solano County, California is proposed. The Suisun Habitat Management, Preservation, and Restoration Plan is intended to balance the benefits of tidal wetland restoration with other habitat uses by evaluating alternatives that provide an acceptable change in land uses, such as salt marsh harvest mouse habitat, managed wetlands, public use, and upland habitat. Suisun Marsh is the largest contiguous brackish water marsh remaining on the west coast of North America and is a critical part of the San Francisco Bay/Sacramento-San Joaquin River Delta estuary ecosystem. It is home to public waterfowl hunting areas and 158 private duck clubs. The Marsh encompasses more than 10 percent of Californias remaining natural wetlands and provides important habitat for more than 221 bird species, 45 mammalian species, 16 different reptile and amphibian species, and more than 40 fish species. Approximately 200 miles of levees in the Marsh contribute to managing salinity in the Sacramento-San Joaquin River Delta. Large open spaces and proximity to urban areas make the Marsh ideally suited for wildlife viewing, hiking, canoeing, and other recreation opportunities. A group of local, state, and federal agencies with primary responsibility for management are pursuing the Suisun Marsh Plan (SMP), and this final EIS describes three alternative 30-year plans, as well as a No Action Plan. The total amount of existing managed wetlands and uplands that could be affected by SMP activities is 52,112 acres. Under Alternative A, which is the proposed project and preferred alternative, 5,000 to 7,000 acres would be restored to self-sustaining tidal wetland and the remaining 44,000 to 46,000 acres of managed wetlands would be enhanced for levee stability and flood and drain capabilities. Alternative B and Alternative C would restore 2,000 to 4,000 acres and 7,000 to 9,000 acres of tidal wetland, respectively. Land suitable for restoration would be acquired only from willing sellers. Activities would include: breaching or lowering existing levees; upgrading or constructing new levees; grading pond bottoms; installing or replacing pipe, drain pumps, and platforms; replacing riprap and water control structures; installing alternate bank protection; constructing cofferdams; installing new fish screens; repairing or replacing salinity monitoring stations; and dredging from tidal sloughs. Over the 30-year SMP implementation period, it is expected that the exact habitat amount provided by restored areas will depend on the existing elevation of the site, sedimentation rates and accretion, and sea level rise. The amount of subtidal aquatic habitat is expected to decrease gradually as sediment accretes and emergent tidal vegetation is established at each restoration site. As this happens, the site will be restored to a tidal wetland. POSITIVE IMPACTS: Development of a regional plan would balance implementation of the CALFED Program, the Suisun Marsh Preservation Agreement, and other management and restoration programs in a manner responsive to the concerns of stakeholders and based upon voluntary participation by private landowners.

Under Alternative A, which is the proposed project and preferred alternative, 5,000 to 7,000 acres would be restored to self-sustaining tidal wetland and the remaining 44,000 to 46,000 acres of managed wetlands would be enhanced for levee stability and flood and drain capabilities. Alternative B and Alternative C would restore 2,000 to 4,000 acres and 7,000 to 9,000 acres of tidal wetland, respectively. Land suitable for restoration would be acquired only from willing sellers. Activities would include: breaching or lowering existing levees; upgrading or constructing new levees; grading pond bottoms; installing or replacing pipe, drain pumps, and platforms; replacing riprap and water control structures; installing alternate bank protection; constructing cofferdams; installing new fish screens; repairing or replacing salinity monitoring stations; and dredging from tidal sloughs. Over the 30-year SMP implementation period, it is expected that the exact habitat amount provided by restored areas will depend on the existing elevation of the site, sedimentation rates and accretion, and sea level rise. The amount of subtidal aquatic habitat is expected to decrease gradually as sediment accretes and emergent tidal vegetation is established at each restoration site. As this happens, the site will be restored to a tidal wetland. POSITIVE IMPACTS: Development of a regional plan would balance implementation of the CALFED Program, the Suisun Marsh Preservation Agreement, and other management and restoration programs in a manner responsive to the concerns of stakeholders and based upon voluntary participation by private landowners. Under the preferred plan, 5,000 to 7,000 acres would be restored as tidal wetlands and tidal aquatic habitat would increase by 250 to 1,050 acres. Fish habitat would be improved due to increased oxygen concentrations in tidal channels and shorebird and waterfowl populations would benefit from improved nesting and winter habitat. The potential for catastrophic flooding would be reduced. NEGATIVE IMPACTS: Construction-related emissions would exceed draft local standards for restoration and management activities; and noise-sensitive land uses would be exposed to noise from portable pump operations. Construction and dredging could damage pipelines and disrupt electrical, gas, or other energy supplies.

AN - 928982001; 15175-9_0006 AB - PURPOSE: A comprehensive plan to address conflicts regarding use of resources within Suisun Marsh, Solano County, California is proposed. The Suisun Habitat Management, Preservation, and Restoration Plan is intended to balance the benefits of tidal wetland restoration with other habitat uses by evaluating alternatives that provide an acceptable change in land uses, such as salt marsh harvest mouse habitat, managed wetlands, public use, and upland habitat. Suisun Marsh is the largest contiguous brackish water marsh remaining on the west coast of North America and is a critical part of the San Francisco Bay/Sacramento-San Joaquin River Delta estuary ecosystem. It is home to public waterfowl hunting areas and 158 private duck clubs. The Marsh encompasses more than 10 percent of Californias remaining natural wetlands and provides important habitat for more than 221 bird species, 45 mammalian species, 16 different reptile and amphibian species, and more than 40 fish species. Approximately 200 miles of levees in the Marsh contribute to managing salinity in the Sacramento-San Joaquin River Delta. Large open spaces and proximity to urban areas make the Marsh ideally suited for wildlife viewing, hiking, canoeing, and other recreation opportunities.

The Suisun Habitat Management, Preservation, and Restoration Plan is intended to balance the benefits of tidal wetland restoration with other habitat uses by evaluating alternatives that provide an acceptable change in land uses, such as salt marsh harvest mouse habitat, managed wetlands, public use, and upland habitat. Suisun Marsh is the largest contiguous brackish water marsh remaining on the west coast of North America and is a critical part of the San Francisco Bay/Sacramento-San Joaquin River Delta estuary ecosystem. It is home to public waterfowl hunting areas and 158 private duck clubs. The Marsh encompasses more than 10 percent of Californias remaining natural wetlands and provides important habitat for more than 221 bird species, 45 mammalian species, 16 different reptile and amphibian species, and more than 40 fish species. Approximately 200 miles of levees in the Marsh contribute to managing salinity in the Sacramento-San Joaquin River Delta. Large open spaces and proximity to urban areas make the Marsh ideally suited for wildlife viewing, hiking, canoeing, and other recreation opportunities. A group of local, state, and federal agencies with primary responsibility for management are pursuing the Suisun Marsh Plan (SMP), and this final EIS describes three alternative 30-year plans, as well as a No Action Plan. The total amount of existing managed wetlands and uplands that could be affected by SMP activities is 52,112 acres. Under Alternative A, which is the proposed project and preferred alternative, 5,000 to 7,000 acres would be restored to self-sustaining tidal wetland and the remaining 44,000 to 46,000 acres of managed wetlands would be enhanced for levee stability and flood and drain capabilities. Alternative B and Alternative C would restore 2,000 to 4,000 acres and 7,000 to 9,000 acres of tidal wetland, respectively. Land suitable for restoration would be acquired only from willing sellers. Activities would include: breaching or lowering existing levees; upgrading or constructing new levees; grading pond bottoms; installing or replacing pipe, drain pumps, and platforms; replacing riprap and water control structures; installing alternate bank protection; constructing cofferdams; installing new fish screens; repairing or replacing salinity monitoring stations; and dredging from tidal sloughs. Over the 30-year SMP implementation period, it is expected that the exact habitat amount provided by restored areas will depend on the existing elevation of the site, sedimentation rates and accretion, and sea level rise. The amount of subtidal aquatic habitat is expected to decrease gradually as sediment accretes and emergent tidal vegetation is established at each restoration site. As this happens, the site will be restored to a tidal wetland. POSITIVE IMPACTS: Development of a regional plan would balance implementation of the CALFED Program, the Suisun Marsh Preservation Agreement, and other management and restoration programs in a manner responsive to the concerns of stakeholders and based upon voluntary participation by private landowners. Under the preferred plan, 5,000 to 7,000 acres would be restored as tidal wetlands and tidal aquatic habitat would increase by 250 to 1,050 acres. Fish habitat would be improved due to increased oxygen concentrations in tidal channels and shorebird and waterfowl populations would benefit from improved nesting and winter habitat. The potential for catastrophic flooding would be reduced. NEGATIVE IMPACTS: Construction-related emissions would exceed draft local standards for restoration and management activities; and noise-sensitive land uses would be exposed to noise from portable pump operations. Construction and dredging could damage pipelines and disrupt electrical, gas, or other energy supplies.

Nitrogen (N) stable isotope ratios (15N:14N) in dated sediments from 25 remote Northern Hemisphere lakes show a coherent signal of an isotopically distinct source of N to ecosystems beginning in 1895 plus or minus 10 years ( plus or minus 1 standard deviation). Initial shifts in N isotope composition recorded in lake sediments coincide with anthropogenic CO2 emissions but accelerate with widespread industrial Nr production during the past half century. Although current atmospheric Nr deposition rates in remote regions are relatively low, anthropogenic N has probably influenced watershed N budgets across the Northern Hemisphere for over a century.

The goal of the study was to select the algorithm which provides the highest and the most uniform SST accuracy within the area observed by the geostationary sensor. The previously established algorithms, such as Non-Linear Regression (NLR) and Optimal Estimation (OE) were implemented along with two new algorithms, Incremental Regression (IncR) and Corrected Non-Linear Regression (CNLR), developed within preparations for the GOES-R ABI mission. OE, IncR and CNLR adopt the first guesses for SST and brightness temperatures (BT) and retrieve deviations of SST from the first guess (increments). OE retrieves SST increments with inversion of the radiative transfer model, whereas CNLR and IncR use regression equations. The difference between CNLR and IncR is that CNLR uses NLR coefficients, whereas IncR implies optimization of coefficients specifically for incremental formulation. Accuracy and precision of SST retrievals were evaluated by comparison with drifting buoys. The major observations from this study are as follows: 1) all algorithms adopting first guesses for SST and BTs are capable of improving SST accuracy and precision over NLR; and 2) IncR delivers the highest overall SST precision and the most uniform distributions of regional SST accuracy and precision. This paper also addresses implementation and validation issues such as bias correction in simulated BTs; preserving sensitivity of incremental SST retrievals to true SST variations; and selection of criteria for optimization and validation of incremental algorithms.

We developed and applied a multi-species, individual-based model to examine the long-term effects of increasing number of reefs on fish weight, abundance, and biomass. The model simulated the population dynamics of three fish species for 50 years on a 2-dimensional spatial grid. Growth, mortality, and movement were computed each hour for individuals of red snapper (Lutjanus campechanus), a croaker-like species (Micropogonias chromis), and a pinfish-like species (Lagodon rhomboides). We also included individuals of two other species (bluefish -Pomatomus saltatrix and a generic jack-like species), but only simulated their hourly movement and their effects on prey and predation of the focal species. The densities of five prey groups were simulated independently in each cell. Our results showed that increasing the number of reefs generally produced higher biomass, but at the cost of slower growth, and smaller individuals. Abundance was higher under fixed-AR recruitment and maximum refuge treatments. In all treatments there were diminishing returns on abundance and biomass with increasing number of artificial reefs. Experiment 2 showed that model results based on regularly spaced reefs were consistent with a real layout of reefs currently being sampled in the northern Gulf of Mexico. Management strategies for determining the habitat-value of reefs in the Gulf of Mexico should consider the number of reefs and the local spatial layout of the reefs to ensure they are optimally arranged.

[Part 1 of 1] T2 - AMENDMENT 18A TO THE FISHERY MANAGEMENT PLAN FOR THE SNAPPER GROUPER FISHERY OF THE SOUTH ATLANTIC REGION. AN - 928982003; 15170-4_0001 AB - PURPOSE: Amendment 18A to the Snapper Grouper Fishery Management Plan (FMP) for the South Atlantic Exclusive Economic Zone is proposed to limit participation and effort in the black sea bass fishery. Recent amendments to the Snapper Grouper FMP have imposed more restrictive harvest limitations on snapper grouper fishermen and a greater number of fishermen may be targeting black sea bass. A combination of a rebuilding stock and effort shifts into the fishery for black sea bass have caused the commercial quota to be met earlier and earlier each fishing season. Amendment 17B to the FMP established strict accountability measures (AMs) for black sea bass that close the fishery when the commercial and recreational annual catch limits are met or projected to be met. To prevent AMs from being triggered early each fishing season, and associated negative social and economic impacts, the South Atlantic Fishery Management Council has determined action should be taken to modify the current rebuilding strategy, reduce participation and effort in the black sea bass pot component of the snapper grouper fishery, and adjust the current system of accountability in the recreational sector. Proposed measures include: the establishment of an endorsement program and other modifications to the commercial black sea bass pot fishery; increasing minimum size limits for both commercial and recreational fisheries; and the establishment of measures to improve data reporting in the commercial and for-hire sectors of the snapper grouper fishery. Preferred alternatives would: define a rebuilding strategy for black sea bass that maintains a constant fishing mortality rate throughout the remaining years of the rebuilding timeframe; limit endorsement to entities with a valid unlimited snapper grouper permit whose average annual landings over a 12-year period using black sea bass pot gear were at least 2,500 pounds; establish a 90-day period to accept appeals to the black sea bass endorsement program; require that each black sea bass pot have an attached valid identification tag; limit the black sea bass pot tags to 35 per vessel each permit year; require that black sea bass pots be brought back to shore at the conclusion of each trip; increase the recreational size limit from 12 inches to 13 inches total length and the commercial size limit from 10 inches to 11 inches total length; establish a 1,000 pounds gross weight commercial trip limit; and provide the option for fishermen to submit their logbook entries electronically. POSITIVE IMPACTS: The proposed amendment would address issues that have arisen as a result of a more stringent regulatory regime in the South Atlantic region. Measures to limit participation in black sea bass component of the of the snapper grouper fishery and slow the rate of harvest would prevent the progressive shortening of the commercial and recreational fishing seasons. NEGATIVE IMPACTS: Fishermen who do not qualify to receive a black sea bass pot endorsement would be limited to black sea bass using hook-and-line gear only and would incur a reduction in net revenue. Profits may also be lost as a result of the implementation of a commercial trip limit, a reduced bag limit, and increased size limits due to likely decreases in per-trip yield and trip quality. The requirement to return black sea bass pots to shore may force vessels to stay longer at sea. A significant amount of administrative time and resources would be spent on developing the endorsement, processing initial endorsement issuances, and maintaining the program throughout its duration.

In these cases, the vapor and liquid must be physically separated (without change to either), before the individual phases can be collected and analyzed. It is not possible to analyze two-phase flows otherwise. Although the two phases are at equilibrium, it is imperative that no liquid contaminate the vapor, and no vapor be entrained in the liquid at a given temperature and pressure. In this paper, we describe a simple on-line device that can individually separate and collect the vapor and liquid phases of a two-phase flow. The apparatus, which we call P super(2SC, uses an adaptation of the branch point separator, with vapor collection done downstream in a metal bellows. The liquid collection is done in a length of Teflon tube. The separated vapor and liquid phases are then easily transferred into any desired analytical instrument with a syringe, although any sample introduction method, such as a valve, could be used as well. We discuss the application of this device with a stream of thermally stressed rocket kerosene.)

AN - 959102072; 2012-036019 AB - If we reduce fossil fuel emissions and slow the Arctic warming rate, can we delay or even avoid the permafrost carbon tipping point? Permafrost currently contains about 1466 Gt of carbon frozen during or since the last ice age. The permafrost carbon tipping point occurs when the release of carbon from thawing permafrost overpowers enhanced uptake due to warmer temperatures. The tipping point indicates when the Arctic irreversibly changes from a carbon sink to a source relative to the atmosphere and marks the start of the Permafrost Carbon Feedback. The tipping point is irreversible because once the carbon thaws and decays into the atmosphere, there is no way to put the carbon back into the permafrost. Projections based on the A1B IPCC scenario indicate that the PCF tipping point will occur between 2020 and 2030, with a total of 190+ or -64 Gt of carbon released into the atmosphere by 2300. We ran a series of model projections out to 2300 based on the A1B scenario, but capped emissions at various levels, each representing a different overall Arctic warming. We present the area of permafrost lost, the permafrost carbon tipping point, and total permafrost carbon flux as a function of Arctic temperature increase. We show the maximum allowed Arctic temperature increase before initiating the permafrost carbon feedback.

The accuracy of the global marine gravity field is limited by the availability of non-repeat altimeter data. Current models, having accuracies of 3-5 milligals (e.g., S&S V18 and DNSC08), are based on the non-repeat data collected by Geosat (18 mo.) and ERS-1 (12 mo.) which use altimeter technology from the 70's and 80's, respectively. Over the next 3 to 5 years, a wealth of new marine gravity data will be provided by three currently operating satellite altimeters CryoSat, Jason-1, and Envisat. With careful processing of the data, in combination with data from past Geosat and ERS-1/GM altimeter missions, we expect to improve the accuracy of the global marine gravity field by at least a factor of two and in some areas a factor of four. In addition to track coverage, the accuracy of the recovered gravity field depends on the accuracy of the arrival time parameter. We have developed an optimized retracking algorithm for CryoSat in the LRM mode and show that the arrival time estimated from CryoSat is 1.4 times better than Geosat and ERS-1. This is consistent with a 2 times higher pulse repetition frequency for CryoSat. We are currently developing a retracking algorithm for CryoSat in the SAR mode and expect a factor of 2 or more improvement in the accuracy of the arrival time. CryoSat has been collecting ocean data for 1.5 years and the ground track density is now adequate to make significant improvements in the marine gravity field. We will construct an improved global gravity model based on these data and provide an evaluation at the meeting.

The number of Santa Ana days per winter season is approximately 20% fewer in the mid 21st century compared to the late 20th century. Since the only systematic and sustained difference between these two periods is the level of anthropogenic forcing, this effect is anthropogenic in origin. In both time periods, Santa Ana winds are partly katabatically-driven by a temperature difference between the cold wintertime air pooling in the desert against coastal mountains and the adjacent warm air over the ocean. However, this katabatic mechanism is significantly weaker during the mid 21st century time period. This occurs because of the well-documented differential warming associated with transient climate change, with more warming in the desert interior than over the ocean. Thus the mechanism responsible for the decrease in Santa Ana frequency originates from a well-known aspect of the climate response to increasing greenhouse gases, but cannot be understood or simulated without mesoscale atmospheric dynamics. In addition to the change in Santa Ana frequency, we investigate changes during Santa Anas in two other meteorological variables known to be relevant to fire weather conditions-relative humidity and temperature. We find a decrease in the relative humidity and an increase in temperature. Both these changes would favor fire. A fire behavior model accounting for changes in wind, temperature, and relative humidity simultaneously is necessary to draw firm conclusions about future fire risk and growth associated with Santa Ana events. While our results are somewhat limited by a relatively small sample size, they illustrate an observed and explainable regional change in climate due to plausible mesoscale processes.

Effects of a Vibrio sp. Probiotic Candidate Upon Survival of Oyster Larvae (Crassostrea virginica) in Pilot-Scale Trials AN - 954644692; 16386728 AB - Environmentally-friendly methods for controlling microbial pathogenesis in aquaculture with probiotic bacteria are becoming increasingly preferred over the use of chemical means, such as disinfectants or antibiotics. Previous research at the Milford Laboratory has shown that naturally-occurring bacteria isolated from the digestive glands of adult oysters (Crassostrea virginica) show promise as potential probiotic additives in oyster larviculture, based on bench-scale experiments. The previous, bench-scale challenge studies reported in the accompanying article (Lim et al. this volume) indicated that 48-h survival of 2-dayold oyster larvae supplemented with Vibrio sp. strain OY15 improved after challenge with pathogenic Vibrio sp. strain B183 compared with the pathogen alone. This study investigated further the effectiveness of probiotic candidate OY15 to improve survival of oyster larvae to metamorphosis under pilot-scale culture conditions, both with and without pathogen B183 challenge. The effective dosage of probiotic candidate OY15 that significantly improved larval survival was determined to be 103 cfu/mL. The LD50 calculated for pathogen B183 was 9.6 104 cfu/mL. Results from these bioassays indicated that addition of probiotic candidate OY15 significantly improved survival of oyster larvae to metamorphosis when challenged with pathogen B183 in pilot-scale trials. These studies can provide the basis for the development of functional foods for use in shellfish larviculture that incorporate a naturally-occurring, probiotic bacterial strain.

Isolation and Screening for Bioactivity AN - 954644689; 16386727 AB - Hatchery production of shellfish seed is necessary to supplement natural recruitment, which is constrained by various stresses, including habitat loss, pollutant contamination, overfishing, and climate change. Bacterial diseases are considered to be a major cause of mortality in hatchery shellfish larviculture; however, overuse of antimicrobials can result in development of resistant strains of bacterial pathogens. The use of probiotics for disease prevention and improved nutrition in aquaculture is becoming increasingly popular as the demand for environmentally-friendly aquaculture grows. The objective of this study was to isolate and evaluate the efficacy of new probiotic bacteria that, incorporated into functional foods for use in shellfish hatcheries, may significantly improve larval survival. First, 26 probiotic-candidate bacteria were isolated from oysters, scallops, and a mass culture of green algae. Fifteen of these isolates (8 oyster strains and 7 bay scallop strains) inhibited known scallop-pathogen bacterial strains B183 and B122 in disk-diffusion assays. Similar to control (unchallenged) oyster larvae, survival of oyster larvae exposed to these 15 probiotic candidates for 48 h was more than 90%. The probiotic candidates were then reisolated from challenged larvae and characterized by Gram stain, colony morphology on solid agar, and the Biolog Bacterial Identification System, finding only 7 distinct strains. Using 12-well microplate assays, 5-day challenges were performed to confirm positive effects of these 7 probiotic candidates on larval survival when challenged with pathogen B183. Oyster larvae exposed to probiotic candidate OY15 had the highest survival; furthermore, survival of pathogen-challenged larvae was significantly improved by the presence of OY15 compared with pathogen alone. In addition, probiotic candidate OY15 exhibited no toxic effects on the microalgal feed strain Isochrysis sp. (T-ISO) in the range of 102-104 cfu/mL. Future studies will confirm optimal dosage and positive effects of probiotic candidate OY15 on survival during long-term rearing of oyster larvae.

Here, we disperse gold, silver, cerium oxide, and positively-charged polystyrene nanoparticles in cell culture media, using the timing between mixing steps to control agglomerate size in otherwise identical media. These protein-stabilized dispersions are generally stable for at least two days, with mean agglomerate sizes of similar to 23 nm silver nanoparticles ranging from 43-1400 nm and average relative standard deviations of less than 10%. Mixing rate, timing between mixing steps and nanoparticle concentration are shown to be critical for achieving reproducible dispersions. We characterize the size distributions of agglomerated nanoparticles by further developing dynamic light scattering theory and diffusion limited colloidal aggregation theory. These theories frequently affect the estimated size by a factor of two or more. Finally, we demonstrate the importance of controlling agglomeration by showing that large agglomerates of silver nanoparticles cause significantly less hemolytic toxicity than small agglomerates.

The stock and fishery range from Massachusetts to North Carolina. The assessment and management of the summer flounder fishery has been very contentious since implementation of the joint Atlantic States Marine Fisheries Commission/Mid-Atlantic Fishery Management Council Fishery Management Plan (FMP) in 1989, when the poor status of the summer flounder stock was evident to scientists, managers, and fishermen. Management efforts to control fishing mortality in the face of increasing stock abundance and competing demand for fish from both the commercial and recreational sectors continue to evoke the question of "How much fish is enough?" to provide for long-term sustainability. In spite of the numerous controversies, however, by 2010 the fishing mortality on summer flounder had declined to its lowest level in at least 30 years, and summer flounder stock biomass was the highest since the stock assessments began in the 1960s. From a scientific perspective, future assessments need to: (a) better account for the uncertainty resulting from "internal model" retrospective error, (b) better integrate environmental, ecological, and other non-traditional calibration indices into the modeling framework, and (c) better discern summer flounder stock-recruitment dynamics by considering covariates such as environmental factors and predator/prey abundance. Initiatives are underway to acquire improved fishery and biological data to allow the assessments to better reflect the true "state of nature."

We used manual acoustic telemetry coupled with global positioning technology to track the detailed spatially explicit daily movements (24 h) of multiple individuals of two common Caribbean fish species, Haemulon sciurus (bluestriped grunt) and Lutjanus apodus (schoolmaster snapper). Movement pathways and day and night activity spaces were mapped and quantified in a Geographic Information System (GIS). Directional sun-synchronous migrations occurred close to astronomical sunset and sunrise. Site fidelity within day and night activity spaces was high. Nine of twelve individuals exhibited overlap of day and night activity spaces and three fish (L. apodus) exhibited complete spatial segregation. Night activity spaces (H. sciurus: 11,309 plus or minus 3,548 m super(2); L. apodus: 9,950 plus or minus 3,120 m super(2)) were significantly larger than day activity spaces (H. sciurus: 2,778 plus or minus 1,979 m super(2); L. apodus: 1,291 plus or minus 636 m super(2)). The distance between sequential position fixes (step lengths) was significantly greater at night than day, indicative of nocturnal foraging and day resting behavior. Integrating acoustic telemetry, GIS techniques and spatial statistics to study fish movement behavior revealed both individual variability and some broader generality in movement paths and activity spaces suggestive of complex underlying behavioral mechanisms influencing diel movements.

Acoustic telemetry revealed variation in movement among individuals that was related to body size. Larger lingcod tended to leave the release reef sooner than smaller lingcod. Four lingcod left the reefs less than 10 days after release, while three lingcod left between one and 4 months after release. Seven lingcod remained at the release reefs for the entire 5-month study, though they did make apparent short-term (< 24 h duration) excursions away from the reefs. Data suggest that the frequency and duration of excursions increase with age and size in both wild and hatchery lingcod. Movement data from these hatchery lingcod and previously published studies on wild lingcod are compared.

In this study, we compare the CFSR tropospheric analyses to two ensembles of analyses. The first ensemble consists of 12 h analyses from various operational analyses for the year 2007. This ensemble shows how well the CFSR analyses can capture the daily variability. The second ensemble consists of monthly means from the available reanalyses from the years 1979 to 2009 which is used to examine the trends. With the 2007 ensemble, we find that the CFSR captures the daily variability in 2007 better than the older reanalyses and is comparable to the operational analyses. With the ensemble of monthly means, the CFSR is often the outlier. The CFSR shows a strong warming trend in the tropics which is not seen in the observations or other reanalyses.

The oceanic component of CFSR includes many advances: (a) the MOM4 ocean model with an interactive sea-ice, (b) the 6 h coupled model forecast as the first guess, (c) inclusion of the mean climatological river runoff, and (d) high spatial (0.5 degree 0.5 degree ) and temporal (hourly) model outputs. Since the CFSR will be used by many in initializing/validating ocean models and climate research, the primary motivation of the paper is to inform the user community about the saline features in the CFSR ocean component, and how the ocean reanalysis compares with in situ observations and previous reanalysis. The net ocean surface heat flux of the CFSR has smaller biases compared to the sum of the latent and sensible heat fluxes from the objectively analyzed air-sea fluxes (OAFlux) and the shortwave and longwave radiation fluxes from the International Satellite Cloud Climatology Project (ISCCP-FD) than the NCEP/NCAR reanalysis (R1) and NCEP/DOE reanalysis (R2) in both the tropics and extratropics. The ocean surface wind stress of the CFSR has smaller biases and higher correlation with the ERA40 produced by the European Centre for Medium-Range Weather Forecasts than the R1 and R2, particularly in the tropical Indian and Pacific Ocean. The CFSR also has smaller errors compared to the QuickSCAT climatology for September 1999 to October 2009 than the R1 and R2. However, the trade winds of the CFSR in the central equatorial Pacific are too strong prior to 1999, and become close to observations once the ATOVS radiance data are assimilated in late 1998. A sudden reduction of easterly wind bias is related to the sudden onset of a warm bias in the eastern equatorial Pacific temperature around 1998/1999. The sea surface height and top 300 m heat content (HC300) of the CFSR compare with observations better than the GODAS in the tropical Indian Ocean and extratropics, but much worse in the tropical Atlantic, probably due to discontinuity in the deep ocean temperature and salinity caused by the six data streams of the CFSR. In terms of climate variability, the CFSR provides a good simulation of tropical instability waves and oceanic Kelvin waves in the tropical Pacific, and the dominant modes of HC300 that are associated with El Nino and Southern Oscillation, Indian Ocean Dipole, Pacific Decadal Oscillation and Atlantic Meridional Overturning Circulation.

Understanding the rates of uptake and elimination for microcystins as well as the transfer efficiency into tissues of consumers are important for determining the potential for microcystins to be transferred up the food web and for predicting potential human health impacts. The main objective of this work was to conduct laboratory experiments to investigate the kinetics of toxin accumulation in fish tissue. An oral route of exposure was employed in this study, in which juvenile yellow perch (Perca flavescens) were given a single oral dose of 5 or 20 mu g of microcystin-LR (MC-LR) via food and accumulation in the muscle, liver, and tank water were measured over 24 h. Peak concentrations of the water soluble fraction of microcystin were generally observed 8-10 h after dosing in the liver and after 12-16 h in the muscle, with a rapid decline in both tissues by 24 h. Up to 99% of the total recoverable (i.e., unbound) microcystin was measured in the tank water by 16 h after exposure. The relatively rapid uptake and elimination of the unbound fraction of microcystin in the liver and muscle of juvenile yellow perch within 24 h of exposure indicates that fish consumption may not be a major route of human exposure to microcystin, particularly in the Great Lakes.

The deployments were a component of a joint NOAA-U.S. Geological Survey (USGS) research effort to improve definition of the rainfall conditions that trigger debris flows from steep topography within recent wildfire burn areas. A procedure was implemented to blend various dual-polarized estimators of precipitation (for radar observations taken below the freezing level) using threshold values for differential reflectivity and specific differential phase shift that improves the accuracy of the rainfall estimates over a specific burn area sited with terrestrial tipping-bucket rain gauges. The portable radar outperformed local Weather Surveillance Radar-1988 Doppler (WSR-88D) National Weather Service network radars in detecting rainfall capable of initiating post-fire runoff-generated debris flows. The network radars underestimated hourly precipitation totals by about 50%. Consistent with intensity-duration threshold curves determined from past debris-flow events in burned areas in Southern California, the portable radar-derived rainfall rates exceeded the empirical thresholds over a wider range of storm durations with a higher spatial resolution than local National Weather Service operational radars. Moreover, the truck-mounted C-band radar dual-polarimetric-derived estimates of rainfall intensity provided a better guide to the expected severity of debris-flow events, based on criteria derived from previous events using rain gauge data, than traditional radar-derived rainfall approaches using reflectivity-rainfall relationships for either the portable or operational network WSR-88D radars. Part of the reason for the improvement was due to siting the radar closer to the burn zone than the WSR-88Ds, but use of the dual-polarimetric variables improved the rainfall estimation by ~12% over the use of traditional Z-R relationships.

With the new algorithm, the precipitation analysis at a grid box of 8 8 km super(2) is defined in three steps. First, PMW estimates of instantaneous rain rates closest to the target analysis time in both the forward and backward directions are propagated from their observation times to the analysis time using the cloud system advection vectors (CSAVs) computed from the GEO-IR images. The "prediction" of the precipitation analysis is then defined by averaging the forward- and backward-propagated PMW estimates with weights inversely proportional to their error variance. The IR-based precipitation estimates are incorporated if the gap between the two PMW observations is longer than 90 min. Validation tests showed substantial improvements of the KF-based CMORPH against the original version in both the pattern correlation and fidelity of probability density function (PDF) of the precipitation intensity. In general, performance of the original CMORPH degrades sharply with poor pattern correlation and substantially elevated (damped) frequency for light (heavy) precipitation events when PMW precipitation estimates are available from fewer LEO satellites. The KF-based CMORPH is capable of producing high-resolution precipitation analysis with much more stable performance with various levels of availability for the PMW observations.

These methods include the National Mosaic and QPE algorithm package (NMQ), under development at the National Severe Storms Laboratory (NSSL), and the Multisensor Precipitation Estimator (MPE) and High-Resolution Precipitation Estimator (HPE) suites currently operational at National Weather Service (NWS) field offices. The goal of the study is to determine which combination of algorithm features offers the greatest benefit toward operational hydrologic forecasting. These features include automated radar quality control, automated Z-R selection, brightband identification, bias correction, multiple radar data compositing, and gauge-radar merging, which all differ between NMQ and MPE-HPE. To examine the spatial and temporal characteristics of the precipitation fields produced by each of the QPE methodologies, high-resolution (4 km and hourly) gridded precipitation estimates were derived by each algorithm suite for three major precipitation events between 2003 and 2006 over subcatchments within the Tar-Pamlico River basin of North Carolina. The results indicate that the NMQ radar-only algorithm suite consistently yielded closer agreement with reference rain gauge reports than the corresponding HPE radar-only estimates did. Similarly, the NMQ radar-only QPE input generally yielded hydrologic simulations that were closer to observations at multiple stream gauging points. These findings indicate that the combination of Z-R selection and freezing-level identification algorithms within NMQ, but not incorporated within MPE and HPE, would have an appreciable positive impact on hydrologic simulations. There were relatively small differences between NMQ and HPE gauge-radar estimates in terms of accuracy and impacts on hydrologic simulations, most likely due to the large influence of the input rain gauge information.

Two are located in the Olympic Mountains and the other two in the western Cascades; and each has uniquely different topographic characteristics. The flood analysis is based on the maximum daily flow observed during each water year (WY) at each site [i.e., the annual peak daily flow (APDF)], with an initial emphasis on the 12 most recent water years between WY1998 and 2009, and then focusing on a 30-year interval between WY1980 and 2009. The shorter time period coincides with relatively complete passive microwave satellite coverage of integrated water vapor (IWV) over the Pacific basin. The combination of IWV imagery and streamflow data highlights a close link between landfalling atmospheric rivers (ARs) and APDFs (i.e., 46 of the 48 APDFs occurred with landfalling ARs). To complement this approach, the three-decade time series of APDFs, which correspond to the availability of the North American Regional Reanalysis (NARR) dataset, are examined. The APDFs occur most often, and are typically largest in magnitude, from November to January. The NARR is used to assess the composite meteorological conditions associated with the 10 largest APDFs at each site during this 30-year period. Heavy precipitation fell during the top 10 APDFs, and anomalously high composite NARR melting levels averaged ~1.9 km MSL, which is primarily above the four basins of interest. Hence, on average, mostly rain rather than snow fell within these basins, leading to enhanced runoff. The flooding on the four watersheds shared common meteorological attributes, including the presence of landfalling ARs with anomalous warmth, strong low-level water vapor fluxes, and weak static stability. There were also key differences that modulated the orographic control of precipitation. Notably, two watersheds experienced their top 10 APDFs when the low-level flow was southwesterly, while the other two basins had their largest APDFs with west-southwesterly flow. These differences arose because of the region's complex topography, basin orientations, and related rain shadowing.

The Z sub(DR) data were calibrated and corrected for differential attenuation. The results revealed greater variability in D sub(m) for larger spatial scales. Mean values of delta D sub(m) were respectively around 0.32-0.34, 0.28-0.30, and 0.24-0.26 mm at scales of 20, 10, and 4.5 km, which are representative of footprints of various spaceborne sensors. For a given spatial scale, delta D sub(m) decreases when the mean value of D sub(m) increases. At the 20-km scale the decreasing trend exhibits a factor-of-1.7 decrease of delta D sub(m) when the average D sub(m) changes from 1 to 2 mm. Estimation data suggest that this trend diminishes as the spatial scale decreases. Measurement noise and other uncertainties preclude accurate estimations of D sub(m) variability at smaller spatial scales because for many data points estimated variability values are equal to or less than the expected retrieval errors. Even though they are important for retrievals of absolute values of D sub(m), the details of the drop shape-size relation did not significantly affect estimates of size spatial variability. The polarization cross coupling in simultaneous transmission-simultaneous receiving measurement mode presents another limiting factor for accurate estimations of D sub(m). This factor, however, was not too severe in estimations of the size variability. There are indications that tuning the differential attenuation correction scheme might balance off some possible cross-coupling Z sub(DR) bias if differential phase accumulation is less than approximately 40 degree .

Design: Longitudinal data are from waves 1 and 2 of the National Epidemiological Survey on Alcoholism and Related Conditions (NESARC). Setting: The NESARC is a nation-wide, household-based survey. Participants: A total of 34 653 US resident participants who completed both NESARC waves were included in analyses. Measurements: Primary measures were history of NUPM and Axis I psychopathology at wave 1. Wave 1 personality disorder diagnosis and sociodemographic characteristics were used as control variables. Findings: Design-based logistic regression analyses indicated that life-time and past year NUPM at wave 1 increased risk for onset of psychopathology among those with no history of psychopathology at baseline, with particular risk for non-NUPM substance use and bipolar disorders. Life-time and past year NUPM were associated with recurrence of alcohol and non-NUPM substance use disorders among those with these diagnoses at baseline. In contrast, life-time and past year NUPM was associated with the onset of all examined disorders among those with a different diagnosis at baseline. Conclusions: Non-medical use of prescription medications is a consistent risk factor for the onset and recurrence of psychopathology.

The model was evaluated for its applicability to simulate spatial and temporal variability of runoff generation areas observed on a pasture hillslope in the Sand Mountain region of North Alabama, United States. Three rainfall events of varying intensity and duration were simulated for a highly instrumented pasture hillslope to study the dynamics of runoff generation and runon areas. Calibration and cross validation were performed on all three rainfall events. Performance of the Hortonian Infiltration and Runoff/On-simulated hydrographs was evaluated using root mean squared error, coefficient of determination and Nash-Sutcliffe coefficient of efficiency. The calibrated model for the first event resulted in a root mean squared error of 1.18 m (super 3) (41.7 ft (super 3) ) for runoff volume; the next two events resulted in root mean squared errors of less than 1 m (super 3) (35.3 ft (super 3) ). Similarly, the coefficient of determination and Nash-Sutcliffe coefficient of efficiency values for all three events were greater than 0.70 for the calibrated model. Results from cross validation showed that the Hortonian Infiltration and Runoff/On model-simulated runoffs were in agreement with the observed data. In addition, the model simulated spatial and temporal variations in runoff generation, and runon areas were in agreement with observed variations. Model results helped explain the interactions among hydrologic and climatic characteristics, such as topography, soil parameters, and rainfall variations, and their connections to surface runoff-generation processes. Although the model does not simulate subsurface lateral flow, it shows promise for identifying runoff generation and runon areas for controlling nonpoint source pollution from pasture hillslopes in this and similar regions.

The environment of preservation was the overwhelming determinant of taphonomic state at SSETI sites. Species mix played a subsidiary role. A few consistent trends were observed: for example, Arctica islandica, Strombus luhuanus, Mytilus edulis, and Mercenaria mercenaria tended to be more highly dissolved than others. Mytilus edulis consistently was fragmented more than other species. Otherwise, most species behaved uniquely over a range of EOPs: significant species by EOP interactions were the norm. A taphofacies model is developed to examine further the role of species on the degradational state of the assemblage. Two metrics are described: a taphonomic degradation score describes the overall degradational state of the assemblage from pristine to highly degraded; and a taphonomic signature describes the relative importance of a suite of taphonomic processes. Model simulations show that the impact of species on degradational state is low initially because all shells are in relatively pristine condition shortly after death. The impact is high at intermediate degradational states because factors inherent to the species modulate the time course of taphonomic decay. The impact is low again at highly degraded assemblages, as the taphonomic process brings shell condition to a common denominator of relatively intense degradation regardless of species. Fossil assemblages almost certainly express this continuum in some degree. The consequence is that better preserved assemblages are ones in which species can affect taphofacies character and so similar EOPs may be judged distinctive due to differential dominance by one species or another. Teasing out characteristics that might forewarn the observer in this instance is an important goal. Simulations show that low evenness is an important warning sign.

SSETI retrieved shells from these EOPs after 2, 8, and 13 years. The degree of shell degradation was significantly influenced by species, elapsed time-since-deployment, and EOP. A suite of 'physical' taphonomic processes, such as dissolution, abrasion, discoloration, and edge alteration, increased in severity over the 13 years; fragmentation occurred in some species. Dissolution proceeded apace; however the incidence of chalkiness declined from high levels observed after a few years while the more extreme levels of dissolution, such as the development of a soft or deeply-dissolved surface, rose significantly in frequency. The incidence of original color declined, while fading of original color increased. Brown-to-red and green discoloration rose rapidly in the first eight years and then declined, leaving a faded shell surface. Between-habitat differences in degradation rate were significant for most taphonomic attributes. Between-species differences were minor in comparison. Thus, taphofacies, the product of the independent actions of a suite of taphonomic processes, originate from and provide information on environmental conditions. Species composition has a lesser inherent influence on the outcome. Not uncommonly, the rates of change in shell condition differed significantly between EOPs although the direction of change was coincident. This was particularly true of the summary indices such as maximum discoloration or the average degree of dissolution. The taphonomic process is nonlinear in time. Nonlinearity is EOP-dependent, becoming a defining attribute leading to disparate taphofacies types. Some taphonomic processes cannot proceed expeditiously without prior alteration of the shell through other taphonomic means. Some taphonomic conditions such as chalkiness can be intermediate states. The presumption that similar taphonomic characteristics between EOPs indicate similar environmental processes operating at similar rates is falsified by SSETI sites in which similar taphonomic indices at Year 13 accrued from different time-varying degradational rates during the preceding years.

Transitions in the US household income distribution AN - 911912408; 4255989 AB - In the five decades since Kuznets (1955) published his hypothesis on income inequality, a large and significant portion of the work on income distribution and inequality has involved using cross-sectional data for developmental comparisons at the intra- and international levels. Using cross-sectional data, these studies have tracked inequality trends that were deemed the consequence of growth and technical progress due to fiscal manipulations, such as levying taxes and granting subsidies to satisfy some welfare target. While this prior work provided valuable insight at the macroeconomic level on the interrelationship of development, economic growth, and income inequality, only over the last few decades has the research emphasis shifted from an understanding of the implications of income inequality at the aggregate level to that at the individual level. Using cross-sectional data it is possible to track income groups over time, but not the composition nor the characteristics of these groups, which are likely to change over time and affect their position in the income distribution. On the other hand, with the availability of longitudinal, micro-level data it has become possible to investigate in more detail underlying facets of income distribution, such as income mobility, and the lack of it, among households. Using three panels of the Survey of Income and Program Participation (SIPP) (1993, 1996, and 2001) and building upon the methodological suggestions of Jarvis and Jenkins (1998) and Jenkins (2000), this paper looks at a household's economic and demographic characteristics relative to their position in the income distribution. For example, results indicate that between 1996-1999, 13 million households experienced changes in their annual income that resulted in their moving up or down two or more quintiles in the income distribution. On the other hand, 39 percent of households (38.5 million) remained in the same quintile between 1996-1999 with the majority of these households experiencing intra-quintile movements. Of notable interest is that of those households remaining in the fourth and top quintiles between 1996-1999; 70 percent and 65 percent, respectively, experienced positive intra-quintile gains in income ranging, on average, from $3,550 to $10,812 annually.

We used an analytical approach termed productivity-susceptibility analysis (PSA) to analyze the vulnerability of federally managed Alaska groundfish stocks to overfishing. The focus of the effort was non-target stocks that have limited data available for determining stock status and vulnerability. The PSA approach was originally created to assess risks to bycatch in Australian trawl fisheries and compares productivity attributes (e.g. life-history traits) to factors that determine a stock's susceptibility to fishing impacts, producing a combined score indicative of a stock's relative vulnerability to overfishing. We used a form of the PSA developed by a working group from the U.S. National Marine Fisheries Service specifically for use in assessing vulnerability in federally managed fisheries. Alaska groundfish displayed a wide range of vulnerability scores, and this result was mainly due to variability in productivity scores. Susceptibility scores varied less than productivity scores and were centered on an intermediate value. The inclusion of target stocks in the PSA was valuable for assessing the relative vulnerability of the non-target stocks. Sensitivity analyses indicated that PSAs respond differently to changes in attribute scores depending on their initial conditions, and managers should be careful in interpreting changes in PSA results when stocks are re-evaluated.

Scientists have already paid much attention to the first three objectives and to the development of their indicators. Although there have been some efforts to develop socioeconomic indicators, relatively less attention has been paid to socioeconomic status and the development of its indicators. In addition, the socioeconomic indicators developed to date are not firmly based on economic theory. We (i) discuss the problems with previous approaches to developing socioeconomic indicators; (ii) present theoretical foundations of a multi-attribute utility function (MAUF) approach in developing socioeconomic indicators; (iii) discuss the issues associated with implementing the MAUF approach for fisheries in Alaska; (iv) present, as an example, several socioeconomic indicators developed using the MAUF approach for a fishery off Alaska; and (v) present results from some sensitivity analyses for the form of utility functions and weights. Future directions are also discussed.

The model is forced by large-scale vertical velocity, zonal wind, horizontal advection, and sea surface temperature observed and derived from TOGA COARE. In cloud budget, rainfall is associated with cloud microphysical processes denoted by the net condensation and dynamical processes denoted by hydrometeor change/convergence. Thus, three rainfall types are separated in this scheme. Time-mean analysis shows that the rainfall type associated with hydrometeor loss/convergence only accounts for 27% of total rainfall, which corresponds to downward motions and downward water vapor and hydrometeor mass flux in the mid and lower troposphere. The two other rainfall types associated with the net condensation contribute equally to total rainfall (36%), which are generally related to upward motions and upward water vapor and hydrometeor mass flux throughout the troposphere.

We assessed relationships between human use patterns and debris type. Wave effects on marine debris density were examined using a GIS-based forecasting tool. We assessed the influence of site wave exposure, period, and height on debris quantity. Presence and abundance of debris were related to wave exposure, vegetation type and proximity of the strata to human population and human use patterns. Plastic pieces accounted for the majority of all debris. Small debris (0-5cm) was primarily composed of foam pieces and was frequently affiliated with natural wrack. Large debris (>100cm) was encountered in all marsh habitat types surveyed and was primarily composed of anthropogenic wood and derelict fishing gear. Marsh cleanup efforts should be targeted to specific habitat types or debris types to minimize further damage to sensitive habitats.

Climatologies for free tropospheric aerosol radiative properties in cloud-free air, including light scattering, light absorption, light extinction, single scattering albedo, Aangstrom exponent, hemispheric backscatter fraction and radiative forcing efficiency, from twelve high altitude (2.2-5.1km) measurement platforms are presented at low relative humidity and at standard temperature and pressure. These climatologies utilize data from ten mountaintop observatories in the 20-50 super(o)N latitude band: Mauna Loa, USA; Lulin Mountain, Taiwan; Nepal Climate Observatory - Pyramid; Izana, Spain; Mount Waliguan, China; Beo Moussala, Bulgaria; Mount Bachelor, USA; Monte Cimone, Italy; Jungfraujoch, Switzerland; Whistler Mountain, Canada. Results are also included from two multi-year, in-situ aerosol vertical profiling programs: Southern Great Plains, USA and Bondville, USA. The amount of light absorption and scattering observed at these high altitude sites either peaks in the spring or it has a broad spring to summer enhancement. The seasonal variation of the aerosol single scattering albedo, backscatter fraction and Aangstrom exponent changes from site to site but the timing can be related to aerosol sources and transport processes known to impact the individual sites. The seasonal variation of in-situ aerosol light extinction from these high altitude measurements is in excellent agreement with extinction values derived from CALIPSO lidar measurements. Analysis of the systematic variability among in-situ aerosol properties shows that these relationships can be used to infer aerosol types. In particular, the relationship between single scattering albedo and Aangstrom exponent can indicate the presence of dust aerosol. Radiative forcing efficiency (RFE=aerosol forcing/aerosol optical depth) is used to assess the importance of single scattering albedo and backscatter fraction on aerosol forcing by eliminating aerosol amount (i.e., aerosol optical depth) from the calculation. Variability in monthly cycles of RFE corresponds with changes in single scattering albedo and hemispheric backscatter fraction. Utilizing site-specific, climatological values of single scattering albedo and backscatter fraction to calculate RFE results in departures from the monthly median values of RFE typically in the range 10-30%. The greatest discrepancy occurs for months with low aerosol loading where the observed variability of single scattering albedo and backscatter fraction is the greatest. At most sites the radiative forcing efficiency at low aerosol loading (light scattering<10Mm-1) is slightly less negative (more warming) than at higher aerosol loading.

The model used is the gridded Sacramento (SAC) and kinematic-wave routing models of the National Weather Service (NWS) Hydrology Laboratory's Research Distributed Hydrologic Model (HL-RDHM) operating at an hourly time step. The data assimilation (DA) technique used is variational assimilation (VAR). Assimilating streamflow and soil moisture data into distributed hydrologic models is new and particularly challenging due to the large degrees of freedom associated with the inverse problem. This paper reports findings from the first phase of the research in which we assume, among others, perfectly known hydrometeorological forcing. The motivation for the simplification is to reduce the complexity of the problem in favour of improved understanding and easier interpretation even if it may compromise the goodness of the results. To assess the potential, two types of experiments, synthetic and real-world, were carried out for Eldon (ELDO2), a 795-km2 headwater catchment located near the Oklahoma (OK) and Arkansas (AR) border in the U.S. The synthetic experiment assesses the upper bound of the performance of the assimilation procedure under the idealized conditions of no structural or parametric errors in the models, a full dynamic range and no microscale variability in the in situ observations of soil moisture, and perfectly known univariate statistics of the observational errors. The results show that assimilating in situ soil moisture data in addition to streamflow data significantly improves analysis and prediction of soil moisture and streamflow, and that assimilating streamflow observations at interior locations in addition to those at the outlet improves analysis and prediction of soil moisture within the drainage areas of the interior stream gauges and of streamflow at downstream cells along the channel network. To assess performance under more realistic conditions, but still under the assumption of perfectly known hydrometeorological forcing to allow comparisons with the synthetic experiment, an exploratory real-world experiment was carried out in which all other assumptions were lifted. The results show that, expectedly, assimilating interior flows in addition to outlet flow improves analysis as well as prediction of streamflow at stream gauge locations, but that assimilating in situ soil moisture data in addition to streamflow data provides little improvement in streamflow analysis and prediction though it reduces systematic biases in soil moisture simulation.

Injuries sustained by S. alterniflora and subsequent recovery, varied considerably between debris types. Differences were likely due to dissimilarities in the structure and composition of debris. Tires caused an immediate (within 3weeks) and long-term impact to S. alterniflora; tire footprints remained devoid of vegetation 14months post-removal. Conversely, crab pot impacts were not as abrupt and recovery was short-term (<10months). We suggest that removal programs specifically target habitats that are susceptible to negative impacts (e.g., salt marsh) and prone to debris accumulation. Management would benefit from the inclusion of habitat information in removal databases.

The first algorithm is based on the co-polar correlation coefficient, rho , and the scattering matrix decomposition parameters, Cloud entropy (H), mean scattering angle ( alpha ) and anisotropy (A). While each of these parameters has oil spill signature in it, we find that combining these parameters into a new parameter, F, is a more effective way for oil slick detection. The second algorithm uses the total power of four polarimetric channels image (SPAN) to find the optimal representation of the oil spill signature. Otsu image segmentation method can then be applied to the F and SPAN images to extract the oil slick features. Using the L-band fully polarimetric Uninhabited Aerial Vehicle - synthetic aperture radar (UAVSAR) data acquired during the 2010 Deepwater Horizon oil spill disaster event in the Gulf of Mexico, we are able to successfully extract the oil slick information in the contaminated ocean area.

Alteration of the shoreline, either through the replacement of marshes with anthropogenic structures, such as riprap and bulkheads, or through the replacement of the native marsh grass Spartina sp. (Spartina) with the invasive Phragmites australis (Phragmites), may affect the value of this habitat as a nursery. In this study, we compared the effects of four common shoreline types, bulkheads, riprap, Phragmites marshes, and Spartina marshes, on food availability, feeding, growth, and survival of juvenile blue crabs in adjacent subtidal areas, as well as on the abundance and size of predators in the South River, Maryland. Sites with each shoreline type were randomly selected. We used benthic cores to sample macrobenthic prey and performed gut content analysis on caged crabs to examine food availability and feeding. Growth was estimated using caged crabs. Survival was assayed with a tethering experiment and predators were sampled with a seine net. Riprap had a lower abundance of macrofaunal prey, and the macrofaunal community differed from both marsh types in that it had it had smaller an more opportunistic species such as nematodes and small polychaetes compared to more bivalves and larger polychaetes at the marsh sites; however, gut contents and growth did not vary among shoreline types. Predation pressure on juvenile blue crabs was highest at bulkhead sites and lowest at riprap. Predator abundance did not vary among the shoreline types, though piscine predators were smaller in size near Spartina marshes compared to the other shorelines. We conclude that shoreline hardening substantially reduced the value of shoreline habitats for juvenile blue crabs, but that Spartina and Phragmites are functionally equivalent.

We tested whether juvenile Greenland cod (Gadus ogac Richardson), Atlantic cod (G. morhua L.), and white hake (Urophycis tenuis Mitchill) have higher feeding and growth rates in structurally complex eelgrass habitat compared to barren seafloor or the water column. We conducted five single species field experiments from September 2002-October 2003, to test whether juvenile Greenland cod, Atlantic cod, and white hake had higher feeding and growth rates in structurally complex eelgrass habitat compared to barren seafloor or the water column. In two experiments with G. ogac, growth rates did not differ among habitats in autumn 2002, but in autumn 2003 fish grew fastest in the water column (0.449+/-0.055%.d-1) compared to barren (0.372+/-0.028%.d-1) or eelgrass habitats (0.254+/-0.013%.d-1). In two experiments with G. morhua, growth rates over the winter (2002-2003) did not differ among habitats, but in spring of 2003 growth was significantly greater in eelgrass (0.366+/-0.026%.d-1) compared to barren (0.327+/-0.035%.d-1) or water column habitats (0.065+/-0.013%.d-1). In one experiment with U. tenuis, growth was faster in eelgrass (0.713+/-0.062%.d-1) than barren (0.483+/-0.055%.d-1) or water column habitats (0.271+/-0.040%.d-1). Zooplankton abundance was consistently highest among seafloor habitats (i.e., eelgrass and barren substrate) and lowest in the water column. More food (by weight) was consumed by U. tenuis and G. ogac in eelgrass than other habitats, while G. morhua consumed the most food over barren substrate. Results are generally consistent with predictions of higher growth rates and food rations among seafloor habitats for white hake and Atlantic cod. Greenland cod did not grow as predicted indicating that potential trade-offs in habitat selection may vary with season and the response to habitat is not uniform among species.

AN - 907030821; 21988187 AB - Carbon nanotubes (CNTs) are currently incorporated into various consumer products, and numerous new applications and products containing CNTs are expected in the future. The potential for negative effects caused by CNT release into the environment is a prominent concern and numerous research projects have investigated possible environmental release pathways, fate, and toxicity. However, this expanding body of literature has not yet been systematically reviewed. Our objective is to critically review this literature to identify emerging trends as well as persistent knowledge gaps on these topics. Specifically, we examine the release of CNTs from polymeric products, removal in wastewater treatment systems, transport through surface and subsurface media, aggregation behaviors, interactions with soil and sediment particles, potential transformations and degradation, and their potential ecotoxicity in soil, sediment, and aquatic ecosystems. One major limitation in the current literature is quantifying CNT masses in relevant media (polymers, tissues, soils, and sediments). Important new directions include developing mechanistic models for CNT release from composites and understanding CNT transport in more complex and environmentally realistic systems such as heteroaggregation with natural colloids and transport of nanoparticles in a range of soils.

AN - 905676867; 21964300 AB - Petroleum-derived compounds, including polycyclic aromatic hydrocarbons (PAHs), commonly occur as complex mixtures in the environment. Recent studies using the zebrafish experimental model have shown that PAHs are toxic to the embryonic cardiovascular system, and that the severity and nature of this developmental cardiotoxicity varies by individual PAH. In the present study we characterize the toxicity of the relatively higher molecular weight 5-ring PAHs benzo[a]pyrene (BaP), benzo[e]pyrene (BeP), and benzo[k]fluoranthene (BkF). While all three compounds target the cardiovascular system, the underlying role of the ligand-activated aryl hydrocarbon receptor (AHR2) and the tissue-specific induction of the cytochrome p450 metabolic pathway (CYP1A) were distinct for each. BaP exposure (40μM) produced AHR2-dependent bradycardia, pericardial edema, and myocardial CYP1A immunofluorescence. By contrast, BkF exposure (4-40μM) caused more severe pericardial edema, looping defects, and erythrocyte regurgitation through the atrioventricular valve that were AHR2-independent (i.e., absent myocardial or endocardial CYP1A induction). Lastly, exposure to BeP (40μM) yielded a low level of CYP1A+ signal in the vascular endothelium of the head and trunk, without evident toxic effects on cardiac function or morphogenesis. Combined with earlier work on 3- and 4-ring PAHs, our findings provide a more complete picture of how individual PAHs may drive the cardiotoxicity of mixtures in which they predominate. This will improve toxic injury assessments and risk assessments for wild fish populations that spawn in habitats altered by overlapping petroleum-related human impacts such as oil spills, urban stormwater runoff, or sediments contaminated by legacy industrial activities.

Microarray screening revealed that each type of scaffold structure induced a unique gene expression signature in primary human bone marrow stromal cells (hBMSCs). Hierarchical cluster analysis showed that treatments sorted by scaffold structure and not by polymer chemistry suggesting that scaffold structure was more influential than scaffold composition. Further, the effects of scaffold structure on hBMSC function were mediated by cell shape. Of all the scaffolds tested, only scaffolds with a nanofibrous morphology were able to drive the hBMSCs down an osteogenic lineage in the absence of osteogenic supplements. Nanofiber scaffolds forced the hBMSCs to assume an elongated, highly branched morphology. This same morphology was seen in osteogenic controls where hBMSCs were cultured on flat polymer films in the presence of osteogenic supplements (OS). In contrast, hBMSCs cultured on flat polymer films in the absence of OS assumed a more rounded and less-branched morphology. These results indicate that cells are more sensitive to scaffold structure than previously appreciated and suggest that scaffold efficacy can be optimized by tailoring the scaffold structure to force cells into morphologies that direct them to differentiate down the desired lineage.

AN - 902331778; 21073401 AB - Studies designed to investigate the environmental or biological interactions of nanoscale materials frequently rely on the use of ultrasound (sonication) to prepare test suspensions. However, the inconsistent application of ultrasonic treatment across laboratories, and the lack of process standardization can lead to significant variability in suspension characteristics. At present, there is widespread recognition that sonication must be applied judiciously and reported in a consistent manner that is quantifiable and reproducible; current reporting practices generally lack these attributes. The objectives of the present work were to: (i) Survey potential sonication effects that can alter the physicochemical or biological properties of dispersed nanomaterials (within the context of toxicity testing) and discuss methods to mitigate these effects, (ii) propose a method for standardizing the measurement of sonication power, and (iii) offer a set of reporting guidelines to facilitate the reproducibility of studies involving engineered nanoparticle suspensions obtained via sonication.

The strongest signal reached delta (super 3H) e = 43% at approximately 1750 m depth at station TEW-39 (15 degrees S, 173.1 degrees W). By examining additional profiles, Lupton et al. [2003] found that this is a regional plume which extends for over 1000 km to the northwest but is absent at 170 degrees W only 300 km to the east. The magnitude and depth of the plume implies that it is not the distal plume from the East Pacific Rise, which is weaker (delta (super 3) He = 28%) and lies at 2500 m depth in this area of the south Pacific. During the past decade, we have used ships of opportunity to collect additional helium profiles in an attempt to define the extent of this plume and identify its source. We re-occupied the 1987 TEW-39 station location in 2004 and 2008, and found the plume to still be present with a similar delta (super 3) He signal (38% and 36% respectively) at the same 1750 m depth. Other recent profiles showed that the plume is present all along the northern margin of the Lau Basin over the Tonga Trench between 173 degrees W and 175.5 degrees W with little variation in signal strength. This plume has no detectable signal in temperature, suspended particles, or other hydrothermal properties other than helium. The plume overlies a location so deep (>4000 m) and so distant from active volcanoes that it must be the "far-field" plume from a strong and persistent source. Possible sources include hydrothermal activity in the northern Lau Basin, Machias Seamount, or activity on the flanks of one of the Samoan Islands. While its source remains elusive, it is clear that this helium plume is a major oceanographic feature of the south Pacific which merits further study.

Tarawera in the rhyolitic Okataina Volcanic Centre of the central North Island, New Zealand, erupted in spectacular fashion. Basaltic eruptions at Tarawera produced tall eruption columns, while hydrothermal and phreatomagmatic eruptions at Rotomahana excavated the pre-1886 Lake Rotomahana site, which later filled to form a new lake up to 125 m deep and approximately 5 X larger than its predecessor. The Pink and White Terraces, which were the world's largest silica aprons and buttresses, had formed as a result of discharging thermal waters and deposition of silica on the margins of the pre-1886 lake, and were believed destroyed during the 1886 eruption. The post-eruption landscape was scarred by eruption craters with the largest marking the foci of the phreatomagmatic eruption, which blanketed the area with 10s of m of mud. A combined approximately 250 line km survey of Lake Rotomahana was conducted using two REMUS 100 AUVs simultaneously mapping with multibeam and sidescan sonar. Also fitted were a magnetometer, minature plume recorders (LSS, Eh, temperature, depth) and pH sensors. Surface vessels conducted magnetic surveys (110 line km), CO (sub 2) flux measurements (420 sites), deployed a CTD and Niksin bottles for water properties and sampling (14 stations), and a camera over sites (12) of known venting and/or where the sidescan showed evidence for the terraces. New bathymetric data clearly shows the en-echelon rift of 1886 in the center of the lake and identifies some pre-1886 shoreline. When combined with sidescan sonar images, several of the basal layers of the Pink Terraces were found very near their original, pre-eruption locations. Underwater photographs reveal buttresses of several tiers. Magnetic data show a pronounced positive anomaly in the southern part of the lake, associated with older lavas, and a distinct negative anomaly associated with the Pink Terraces, marking the boundaries of the pre-1886 geothermal field. Bubble plumes recorded during the magnetic survey and also seen on sidescan sonar images show modern hydrothermal activity occurs within the Pink Terraces area, to a lesser degree the White Terraces area, and in two new (post-1886) locations, namely; along the southern boundary of the newly formed rift and an area further eastwards. CTD casts and water column measurements made by the AUVs confirm these areas as primary discharge zones, establishing continuation of hydrothermal activity in the Terraces area and corroborating the existence of a new geothermal system in the southern part of the lake. Maximum helium concentrations show the main discharge source is at a depth of approximately 40 m and when combined with CO (sub 2) flux for the lake, suggests degassing of a sub-lake floor magmatic system.

This is necessary in order to rapidly warn coastal residents in the near field of the rupture and sea floor deformation. Mwp has been used to issue Tsunami Warnings within 5 to 10 minutes of origin time, by both US Tsunami Warning Centers since about 2000. Because Mwp [Tsuboi et. al., 1995] is based on the far-field approximation to the P-wave displacement due to a double couple point source, we should very carefully apply Mwp to data obtained at distances of only about a fault length from the source. However, in the case of a huge earthquake, which occurs just offshore of populated area, like the 2011 Tohoku earthquake, it was reported that seismographs located at close epicentral distances were clipped by large surface waves arrivals. This causes problems when determining earthquake magnitude based on the amplitude of surface waves. Mwp could be useful even for these station located close to the epicenter, because we do not expect the P-waves will clip. We examine broadband STS-1 seismograms around the Japanese Islands, to determine if Mwp can usefully estimate magnitude of great earthquakes using the unclipped portion of broadband seismograms obtained close to the epicenter. Specifically in case of Tohoku, since the duration is less than 200 sec, if the time window to estimate Mwp is around 120-150 sec, there should be a good chance to get reliable Mwp value for epicentral distance 9 to 10 degree stations. Our observations indicate that Mwp gives reliable results as close as 8.3 degrees from the source. At 8.3-9.5 degrees, Mwp gives reliable results of Mw 8.9-9.1 for the Mw9.1 Off East Coat of Tohuku event of March 11, 2011, 4-5 minutes after origin time. We also have examined for the Mw8.8 Chile earthquake of February 27, 2010, and obtained Mwp8.8 at 8.9 degrees from the source, at 4 minutes after origin time. These results demonstrate that Mwp should be applicable to estimate earthquake magnitude promptly using seismographs located close to the epicenter even for magnitude 9 class events. We use broadband seismograms recorded by F-net broadband network operated by NIED in Tsukuba, Japan.

Arctic permafrost currently contains 1466 Gt of carbon frozen since the last ice age, roughly double the amount of carbon in the atmosphere. We estimate 190+ or -64 Gt of this carbon will thaw out, decay, and end up in the atmosphere by 2300, potentially increasing atmospheric CO (sub 2) concentrations by 87+ or -29 ppm. A carbon release of this magnitude is equal to 15% of the total allowed emissions to hit a target CO (sub 2) concentration of 700 ppm. Global targets for fossil fuel emissions must be reduced an additional 15% to account for the release of carbon from thawing permafrost. Current treaty negotiations do not include a 15% allocation for permafrost carbon emissions. We present the scientific basis for our results and summarize our successes and failures in trying to influence international treaty negotiations to reduce fossil fuel emissions.

By 2018, NGS intends that all orthometric heights in the USA will be determined in the field by using a reliable national geoid model to transform geodetic heights obtained from GPS. Towards this end, NGS is updating its terrestrial gravimetry holdings by flying new airborne gravity surveys over a large fraction of the USA and it territories. Such data has already been collected for several areas, including Alaska, the Gulf of Mexico, and elsewhere. Also important are the latest satellite-based models from the GRACE and GOCE missions, which are expected to provide much of the long-wavelength structure of the geoid model. In this study, we contrast and compare the latest airborne- and satellite-derived gravity products where sufficient data is available, thereby seeking to determine the extent to which each can currently be expected to contribute to an improved geoid model. Results of validation through independent geodetic data sets and other gravity-based products are also presented and considered.

However, systems employing erbium-doped fiber lasers operating at 1550 nm are becoming increasingly prevalent. An advantage of this wavelength is enhanced eye safety, as greater water absorption in the ocular components at wavelengths above approximately 1400 nm prevents radiation from reaching the retina. However, for related reasons, 1550 nm lidar systems may be subject to a greater decrease in signal-to-noise ratio (SNR) when the ground surface is wet. When operating near the upper limits of the system's operational altitude range--as is often done in order to maximize acquisition efficiency and minimize costs--this reduced SNR can lead to drop-outs and data gaps. The U.S. National Geodetic Survey (NGS), a program office of the National Oceanic and Atmospheric Administration (NOAA), uses lidar for coastal mapping applications. One of the primary goals is to extract tide-datum based shoreline, which is used in updating nautical charts, defining legal boundaries, and in a variety of coastal science and geomorphology studies. Mapping a tidally-referenced shoreline from topographic lidar data typically involves acquiring the data over exposed areas of the intertidal zone at low tide. Even when not submerged, these areas are frequently wet from the receding tide, wave runup, etc. If not compensated for through appropriate flight planning, the additional decrease in SNR with 1550 nm systems, due to the surface being wet, can lead to sparse, noisy data or even data voids, affecting the ability to extract a tidally-referenced shoreline. This study focuses on a theoretical and empirical investigation of 1550 nm lidar systems for coastal mapping. Lidar data were acquired over Assateague Island, Maryland with a new, dual Riegl LMS-Q680i system at a variety of flying heights. Additionally, reflectance spectra were acquired with a field spectrometer for various East Coast shorelines under differing moisture conditions, including dry, wet, and snow or ice covered. These data were used to quantify the effects on received signal strength and output data, and in determining how to best compensate for reduced SNR through proper selection of flying height and other mission parameters. We conclude with recommendations for effective and efficient operational use of 1550 nm systems for coastal applications.

Enormous progress made in North America over the last 5 decades provides a template for other megacities of the world, especially in developing countries, attempting to achieve rapid economic growth without compromising air quality. While the progress to date has been impressive, many challenges remain including the need to improve air quality while simultaneously mitigating climate change. The impact of pollutant emissions from megacities is felt long distances away from the local sources but no policy mechanisms currently exist to mitigate air quality impacts resulting from such pollution transport.

Recent studies are used that directly compared online and offline simulations to discuss possible shortcomings for both air quality and weather forecasting. The disadvantages of offline approaches are easy to show for air quality forecasting. On the other hand, a positive impact on short to medium range weather forecasts that is significant enough to justify an implementation at operational weather forecasting centers is more difficult to prove, and may initially only come through an improvement of the meteorological data assimilation. Eventually though, a migration to an integrated modeling system will provide new opportunities for weather prediction modelers as well. The simulation of chemical species will allow identification of shortcomings in currently used forecast models as well as lead to better use of meteorological data assimilation.

The ocean biogeochemical component of ESM2M includes representations of pelagic calcite cycling as a function of supersaturation and small phytoplankton grazing, pelagic aragonite cycling as a function of supersaturation and large phytoplankton grazing, and sediment calcite cycling based on a box model representation of bottom water saturation state and the incoming fluxes of calcitic, organic and lithogenic material. The model was forced with historical and future projections of Representative Concentration Pathways (RCPs) of radiatively active gases as part of the fifth Coupled Model Intercomparison Project. Consistent with observations, the ESM2M ocean takes up 2.1 PgC a (super -1) at the end of the 20th century. Under the highest emissions scenario of an 8.5 W m (super -2) targeted radiative forcing with CO2 concentrations of 936 ppm by 2100 (RCP8.5), ESM2M takes up 6.1 PgC a (super -1) at the end of the 21st century. We describe the geographical and vertical extent of ocean acidification and depression of aragonite and calcite saturation states that result in this model. In global comparison with preindustrial conditions, ESM2M suggests severe ecological consequences of acidification under the RCP8.5 scenario with aragonite production being depressed by 17% at the end of the 20th century and 72% at the end of the 21st Century and calcite production being depressed by 16% at the end of the 20th century and 67% at the end of the 21st Century. These results are consistent with previous studies that have similarly assumed linear dependence of aragonite and calcite production with the degree of supersaturation. In terms of acidification mitigation feedbacks, these responses combine to provide additional acid neutralizing capacity in the surface ocean of 0.23 PgC a (super -1) at the end of the 20th century and 0.98 PgC a (super -1) at the end of the 21st Century. However, through changes in the mineral ballasting of sinking organic material, this reduction in aragonite and calcite cycling is also projected to reduce ballasting and shoal the remineralization of organic material with consequences for both dissolved organic carbon and alkalinity cycling. Finally, we also explore the nature of the sediment calcite mitigation feedback on ocean acidification. Our model of sediment calcite cycling gives an estimate of the role of acidification on the exchange of alkalinity with the sediments wherein acidification supplies an additional acid neutralizing capacity of 0.11 PgC a (super -1) at the end of the 20th century, and 0.76 PgC a (super -1) at the end of the 21st Century, 0.14 PgC a (super -1) of which is due to direct reduction in calcite supply to the sea floor. While this flux has been ignored in most ESM efforts to date, this sediment feedback is of similar magnitude to the surface production feedback over the first centuries of acidification and is expected to become increasingly critical to long term mitigation of ocean acidification as the acidification reaches ever deeper into the ocean over time.

Most surveyed areas released CO (sub 2) to the atmosphere. The mean CO (sub 2) flux of surveyed waters was 1.6 mmol m (super -2) d (super -1) . In contrast, the Mississippi River plume in the GOM and the Merrimack River plume in the Gulf of Maine (GoME) were strong biologically-driven CO (sub 2) sinks. The mean aragonite saturation state (Omega A) decreased latitudinally more than two fold (4.1 to 1.8) from northern GOM shelf waters to waters in the GoME. This change was accompanied by a 0.4-unit decrease in mean shelf-water pH (at 25 degrees C). The influence of biologically mediated processes on dissolved inorganic carbon (DIC), nutrients, and O (sub 2) in Gulf Stream Water (GSW) varied substantially with location. In the GOM, the GSW receives approximately 1.4-1.6X10 (super 11) gC d (super -1) of DIC exported from the shelf. Biologically induced chemical changes in GSW along the southeastern U.S. coast were dominated by physical mixing from North Atlantic sub-tropical recirculation. Southward, along-shore transport of the Labrador Coastal Current in the Mid-Atlantic Bight creates a mid-salinity end-member on the shelf. Mixing of the slope and shelf waters with this coastal current accounts for 47% of the total north-south gradient in the mean salinity-normalized DIC, while biological processes account for about 14%. Northeastern U.S. coastal water is vulnerable to ocean acidification due to its low Omega A and low buffer capacity.

The National Geophysical Data Center (NGDC) maintains and archives a comprehensive collection of natural hazards data. The NGDC global historic event database includes all tsunami events, regardless of intensity, as well as earthquakes and volcanic eruptions that caused fatalities, moderate damage, or generated a tsunami. Examining the past record provides clues to what might happen in the future. NGDC also archives tide gauge data from stations operated by the NOAA/NOS Center for Operational Oceanographic Products and Services and the NOAA Tsunami Warning Centers. In addition to the tide gauge data, NGDC preserves deep-ocean water-level, 15-second sampled data as collected by the Deep-ocean Assessment and Reporting of Tsunami (DART) buoys. Water-level data provide evidence of sea-level fluctuation and possible inundation events. NGDC houses an extensive collection of geologic hazards photographs available online as digital images. Visual media provide invaluable pre- and post-event data for natural hazards. Images can be used to illustrate inundation and possible damage or effects. These images are organized by event or hazard type (earthquake, volcano, tsunami, landslide, etc.), along with description and location. They may be viewed via interactive online maps and are integrated with historic event details. The planning required to achieve collection and dissemination of hazard event data is extensive. After a damaging or fatal event, NGDC begins to collect and integrate data and information from many people and organizations into the hazards databases. Sources of data include the U.S. NOAA Tsunami Warning Centers, the U.S. Geological Survey, the U.S. NOAA National Data Buoy Center, the UNESCO Intergovernmental Oceanographic Commission (IOC), Smithsonian Institution's Global Volcanism Program, news organizations, etc.. NGDC then works to promptly distribute data and information for the appropriate audience. For example, when a major tsunami occurs, all of the related tsunami data are combined into one timely resource. NGDC posts a publicly accessible online report which includes: 1) event summary; 2) eyewitness and instrumental recordings from preliminary field surveys; 3) regional historical observations including similar past events and effects; 4) observed water heights and calculated tsunami travel times; and 5) near-field effects. This report is regularly updated to incorporate the most recent news and observations. Providing timely access to authoritative data and information ultimately benefits researchers, state officials, the media and the public.

Conceived in the dawn of the digital age by representatives from U.S. academic and government marine core repositories and the NOAA National Geophysical Data Center (NGDC) at a 1977 meeting convened by the National Science Foundation (NSF), the Index is based on core concepts of community oversight, common vocabularies, consistent metadata and a shared interface. Form and content of underlying vocabularies and metadata continue to evolve according to the needs of the community, as do supporting technologies and access methodologies. The Curators Consortium, now international in scope, meets at partner institutions biennially to share ideas and discuss best practices. NGDC serves the group by providing database access and maintenance, a list server, digitizing support and long-term archival of sample metadata, data and imagery. Over three decades, participating curators have performed the herculean task of creating and contributing metadata for over 195,000 sea floor and lakebed cores, grabs, and dredges archived in their collections. Some partners use the Index for primary web access to their collections while others use it to increase exposure of more in-depth institutional systems. The Index is currently a geospatially-enabled relational database, publicly accessible via Web Feature and Web Map Services, and text- and ArcGIS map-based web interfaces. To provide as much knowledge as possible about each sample, the Index includes curatorial contact information and links to related data, information and images; 1) at participating institutions, 2) in the NGDC archive, and 3) at sites such as the Rolling Deck to Repository (R2R) and the System for Earth Sample Registration (SESAR). Over 34,000 International GeoSample Numbers (IGSNs) linking to SESAR are included in anticipation of opportunities for interconnectivity with Integrated Earth Data Applications (IEDA) systems. To promote interoperability and broaden exposure via the semantic web, NGDC is publishing lithologic classification schemes and terminology used in the Index as Simple Knowledge Organization System (SKOS) vocabularies, coordinating with R2R and the Consortium for Ocean Leadership for consistency. Availability in SKOS form will also facilitate use of the vocabularies in International Standards Organization (ISO) 19115-2 compliant metadata records. NGDC provides stewardship for the Index on behalf of U.S. repositories as the NSF designated "appropriate National Data Center" for data and metadata pertaining to sea floor samples as specified in the 2011 Division of Ocean Sciences Sample and Data Policy, and on behalf of international partners via a collocated World Data Center. NGDC operates on the Open Archival Information System (OAIS) reference model.

The availability of data (for example, that at some locations one knows only that the mass fraction of titanium is below a particular threshold) also influences the uncertainty of the results. Statistical methods are illustrated that can be used to assess and propagate these two sources of uncertainty, with applications to an aerial survey of greenhouse gases, and to geochemical mapping.

In theory, the increased magma supply to the rift should create an abundance of active hydrothermal vent sites, and yet previous surveys found that high-temperature vents were more scarce than predicted. The mission goals of GALREX 2011 were to explore the diverse habitats and geological settings of the deep Galapagos region primarily to search for hydrothermal venting, but also to explore other areas of interest. In June 2011, the first multibeam bathymetric map of the Galapagos Rift axis from 101 degrees 18' W to 98 degrees W was made with the EM302 sonar, and an along-axis "tow-yo" CTD-LSS-ORP hydrocast was conducted for hydrothermal plume signals along with additional EM302 mapping from 89 degrees 18' W to 85 degrees 21' W. In July 2011, the ROV Lil' Hercules explored new sites of hydrothermal venting along the eastern arm of the Rift, the Rosebud hydrothermal vent field, hydrothermal mounds 20 km south of the Rift, one of the Paramount Seamounts for a macrofaunal survey, and a volcano on the Ecuador Rift. Data and ROV video feeds were transmitted by broad-band satellite in real time from the ship to a team of scientists in Seattle, WA; Newport, OR; and Woods Hole, MA. The team evaluated the transmitted data and helped direct seafloor ROV operations in real-time. In total, nearly 4,000 km of seafloor were mapped by EM302, 11 CTD tows covered the entire eastern arm of the Rift, and 12 ROV dives collected > 5 TB of high-definition digital video of the seafloor. The hydrocast survey along the eastern Rift identified two regions with abundant optical and ORP signals directly over the spreading axis. The largest of these was nearly 50 km long between 88 degrees 5' W and 88 degrees 33' W. Five ROV dives near 88 degrees 18' W found recently erupted lobate lava flows and several regions of active diffuse hydrothermal venting. The site had the appearance of a relatively recent eruption as the diffuse venting at the site led to extensive white particles of putative sulfur, presumably of bacterial origin, on the rocks and suspended in the lower water column (hence the high optical signal) and there were only mobile rather than sessile fauna at these vents. Extinct hydrothermal sulfide chimneys over 30 m tall were found within 2 km of the active vents suggesting that the region had previously experienced a period of intense heat loss. Three ROV dives at another plume site near 86 degrees W showed reinvigorated diffuse venting in a once massive clam bed now actively colonized by tubeworms, mussels, and microbial mats and ringed with abundant dandelions. The lack of biota and vitreous, unsedimented lobate flows at the Rosebud diffuse vent field (86 degrees 12' W) suggests that it was paved over by an eruption since 2005. The eastern Galapagos Rift appears to have experienced a series of recent dike injections producing new lava flows and extensive diffuse venting, possibly within the past 5 years. Active, focused high-temperature hydrothermal flow has yet to be found on the eastern Rift, though extinct sulfide chimneys attest that it has occurred.

Light backscattering (Delta NTU) and oxidation-reduction potential (ORP) sensors measured the relative concentration of suspended particles and reduced hydrothermal chemicals, respectively. GALREX was designed to complement a similar survey in 2005/2006 that surveyed the central Galapagos Rift from 94.9 degrees to 89.6 degrees W. That survey found only two active high-temperature vent fields, plus robust plume evidence for at least six smaller fields. The spatial density of hydrothermal plumes (p (sub h) ) along the rift was only 0.11 (based on Delta NTU anomalies), significantly less than expected for intermediate-rate (50-60 mm/yr) spreading but similar to other hotspot-affected ridges (e.g., near the Iceland, Ascension, and St. Paul-Amsterdam hotspots). This low p (sub h) value was hypothesized to be an expression of (1) reduced hydrothermal discharge on ridge sections with hotspot-thickened crust, (2), widespread low-temperature discharge undetectable by large-scale surveys, or (3) episodic venting. GALREX found a distinctly different hydrothermal environment on the eastern third of the rift. Overall, p (sub h) = 0.19, about twice that of the central Galapagos Rift. Strong venting was concentrated in two areas. Most remarkable was a 50-km-long section (88.56 degrees -88.09 degrees W) where continuous plumes with high (>0.2) Delta NTU values rose as high as 250 m above the seafloor. This area is low amplitude valley and ridge topography, centered on a relatively recent lava flow at 88.33 degrees W. The second area included the historical vent fields Rose Garden and Rosebud, and ranged from 86.25 degrees to 85.87 degrees W. In this area Delta NTU was lower ( approximately 0.1) and plumes were patchy. ORP anomalies occasionally occurred in the absence of Delta NTU anomalies, suggesting low-temperature, particle-poor vent sources. No anomalies were detected over the Rose Garden/Rosebud sites. The entire GALREX survey detected approximately 20 discrete ORP anomalies, with along-axis separations ranging from 2 to 110 km (median=14 km). Because ORP anomalies are very short lived, and thus do not advect far from their seafloor source, at least approximately 20 distinct vent "fields" must be active, a higher spatial frequency than found along the central Galapagos Rift. The eastern rift section is also notable for supporting two areas of extensive venting, each >40 km along axis, and each paved by apparently young ( approximately 10 yr) lavas. Each of these areas is approximately 3x longer than the longest hydrothermal area on the central rift section.

Here, we compare the fluxes and the plume dispersal at three high temperature sites located in very diverse settings at comparable depths ( approximately 3000m): The recently discovered sites Turtle Pits, and Nibelungen on the southern MAR, and the Logatchev field in the North Atlantic. Plume mapping for these sites on cruises between 2004 and 2009 consisted of CTD Towyo-, Yoyo,- and station work, including velocity profiling, as well as water sampling for analysis of trace gases (CH (sub 4) , H (sub 2) , (super 3) He/ (super 4) He) and metals; temperature measurements and fluid sampling at the vent sites were carried out with an ROV. The aim of this work is to gain a better understanding of how the setting of a vent site affects the dispersal of the particle plume, and what means can be used to infer possible locations of vent sites based on the hydrographic properties and plume observations, using high resolution bathymetric mapping and hydrographic information. The ultramafic-hosted Nibelungen site (8 degrees 18'S) consists of a single active smoking crater, along with several extinct smokers, which is located off-axis south of a non-transform offset. The setting is characterized by rugged topography, favorable for the generation of internal tides, internal wave breaking, and vertical mixing. Elevated mixing with turbulent diffusivities K (sub rho ) up to 0.1 m (super 2) s (super -1) , 3 to 4 orders of magnitude higher than open ocean values, was observed close to the vent site. The mixing as well as the flow field exhibited a strong tidal cycle; the plume dispersal is thus dominated by the fast and intermittent vertical exchange and characterized by small scale spatial and temporal variability. The Turtle Pits vent fields (4 degrees 48'S) are located on a sill in a north-south orientated rift valley. The site consists of three (known) high temperature fields: Turtle Pits, Comfortless Cove, and Red Lion. The particle plume is confined to the rift valley since the depth of the valley exceeds the rise height of the plume. Velocities observed with a Lowered Acoustic Doppler Current Profiler (LADCP), and the gradient of the stratification across the sill show a hydraulic control of the background flow over the sill, resulting in a northward advection of plume material. Downstream, the particle plume is modified by a dominant across-valley tide, and strong vertical mixing in the wake of the hydraulic jump. The Logatchev hydrothermal field (14 degrees 45'N) consists of seven vent sites, mostly smoking craters, located up on the eastern flank of the axial graben. The current field as observed with LADCP is irregular, but follows to some extent the topography in the range of the particle plume. This plume is sheared in the vertical, indicating the influence of the local tides.

The August swarm lasted for approximately 4 days. Seventy-five earthquakes were reported by the Canadian National Seismograph Nework (CNSN), with the largest having a magnitude of 5.9. The U.S. Navy's Sound Surveillance System (SOSUS) hydrophones reported 148 earthquakes. Over 250 earthquakes were recorded on the Central Oregon Locked Zone Array (COLZA), a temporary array of 15 ocean bottom seismometers (OBS) and hydrophones. The October swarm lasted about 2 days with only one reported CNSN magnitude 4.4 earthquake. This event was also observed with the COLZA network. SOSUS reported 119 earthquakes over the course of two days. In this poster, we use the COLZA T-phase data to better understand the tectonic significance of these swarms. T-phases are generated by earthquakes and converted to acoustic energy at the seafloor. We used the ANSS magnitudes to calibrate an empirical magnitude scale for maximum amplitudes handpicked from the COLZA T-phase observations. This enabled us to lower the magnitude threshold to 2.8. A b-value of 0.78 was obtained for the August swarm suggesting that it may be a tectonic event rather then a magmatic one. Focal mechanisms reported by the Harvard CMT catalog for 3 of the largest events also support strike-slip motion. The reported SOSUS hypocenter locations indicate a linear NE/SW trend west of and parallel to the Explorer Ridge while the ANSS locations are very scattered but suggest a northwest/southeast trend in line with but east of the Dellwood-Revere transform fault. To obtain better-constrained locations, we plan to relocate the events and COLZA T-phase data using cross-correlation techniques developed to locate seismic tremor. We expect the COLZA data will allow us to determine whether activity was primarily focused along the Explorer Ridge axis, along the Dellwood-Revere transform, or within the plate. This investigation could provide us with new insight into the evolution and possible fragmentation of the Explorer Plate.

Baylis. These surveys were conducted between Ft. Bragg, CA and Shelter Cove, CA in an effort to study the offshore section of the Northern San Andreas Fault (NSAF). We have combined multibeam data collected during this cruise with data collected by the California Seafloor Mapping Program to compile high resolution imagery of the entire offshore section of the NSAF. Seismic profiles were collected perpendicular to the fault at 1 km intervals. Two full length profiles were collected parallel to the NSAF. These data have allowed us to map, with high precision, the upper crustal features of the NSAF, and other features in the area. We have also used recently released industry collected multi-channel seismic reflection profiles, contributed by WesternGeco, available through the USGS. These profiles were collected at 10 km spacing and reach subsurface depths of approximately 5km, allowing for investigation of deep structural features. We observed, using bathymetric and seismic data, that the NSAF moves offshore at approximately 340 degrees at Point Arena. At the head of Noyo Canyon, near Ft. Bragg, the NSAF takes a approximately 6 degrees bend to the east, creating an extensional basin. The NSAF passes through Noyo Canyon which has been offset and captured by the main trace of the fault. As the NSAF bends at Noyo Canyon and moves north it is observed bending back approximately 10 degrees to the west near Tolo Bank. Tolo Bank is likely an uplifted block due to the left bend in the right lateral fault. North of Tolo Bank the NSAF comes ashore at Shelter Cove with no other major strike slip features observed to the west. Other interesting features observed are compressional folding and thrust faults striking northwest from, and terminating at, the NSAF. It appears that these are active structures but the amount of slip that is partitioned to these smaller faults is yet unclear. The principal stress axis of the folding/faulting west of the NSAF is consistent with deformation and uplift observed southwest of the Mendocino triple junction Geophysical data collection, 20 days of multibeam and seismic survey, were conducted using the R/V Baylis, a 65' sailing research vessel owned by Sealife Conservation Society, Santa Cruz, CA. In addition, the R/V Pacific Storm, an 86' converted fishing vessel, was used for Autonomous Underwater Vehicle (AUV) dives to gather video imagery of the NSAF. It was not only our goal to study the offshore portion of the NSAF but it was an opportunity to conduct research in an efficient manner. During the entire cruise, mobilization, data collection and demobilization, fuel consumption was recorded. The Baylis averaged 1.6 gallons of fuel per hour (g/hr) while the Pacific Storm consumed 12.9 g/hr. Total fuel consumption for the entire cruise was approximately 4900 gallons (Baylis, 681 gal, Pacific Storm, 3096 gal). For comparison, a similar cruise conducted on an intermediate class ship, i.e. OSU's Wecoma, would consume 30,000-40,000 gallons of fuel.

So you ask yourself, what would you be doing in all of these places? What you would be doing is what hundreds of educators from around the world have done for over 20 years, participating in field-based Teacher Research Experience (TRE) programs. Teacher Research Experiences involve educators from varying grade levels and backgrounds in hands-on research as a member of a scientific research team. The teacher works side by side with actual research scientists, often on tasks similar to a field assistant or graduate student. As an important member of the research team teachers learn more about science content and the process of science. Subsequently, the educators play a key role in digesting and communicating the science to their students and the general public. TRE programs vary in many ways. Programs take place in a variety of settings--from laboratories to field camps, and from university campuses to aircraft or ships. The primary commonality of the TRE programs in this presentation--PolarTREC (Teachers and Researchers Exploring and Collaborating), ANDRILL (ANtarctic geological DRILLing) Research Immersion for Science Educators (ARISE); Integrated Ocean Drilling Program (IODP) School of Rock (SOR); and the National Oceanic and Atmospheric Administration Teacher at Sea (TAS) program--is that these programs provide an authentic field-based research experience for teachers outside of a laboratory setting, frequently in harsh, remote, or unusual settings. In addition, each of these programs is federally funded, possess dedicated program management staff, leverage existing scientific and programmatic resources, and are usually national, and sometimes international, in scope. Sharing their unique lessons learned and program results, authors will describe how TRE's improve and enrich interdisciplinary science education by connecting teachers, researchers, students, and the public around the globe for involvement in scientific research and global issues.

With the January 1998 eruption and the April 2011 eruption discovered during Jason ROV operations in late July this year, that goal has now been accomplished. Based on observations and fluid temperature/chemistry measurements before and after both eruptions, there are common features leading up to and following the eruptions. Both eruptions at Axial originated in the SE corner of the caldera associated with the S Rift Zone. Isolated snowblower vents were found on new lava following both eruptions. Centimeter-thick orange hydrothermal mats formed rapidly on the new lava flows. There is some evidence that the fluids from ASHES vent field, located near the SW caldera wall, were hottest before the 1998 eruption. A second high-temperature vent field is located in the SE caldera just east of the recent lava flows. Lava flows came close to both high-temperature fields in 2011, but did not flow over any known chimneys. Recorded time series for several high-temperature vents show increasing temperatures from 2001 through 2010. Vent fluid chlorinity decreased at ASHES for 0.5 to 2 years following the 1998 eruption. As of 3.5 months after the 2011 eruption, ASHES fluid chlorinity did not change significantly. High gas contents reflect magma degassing throughout the entire history of fluid sampling at Axial. Spatial and temporal patterns of vent fluid chemistry will be presented.

Following retreat of the continental ice sheet ( approximately 14,000 ybp), the Skagit River incised several hundred meters into valley-filling glacial sediments, creating a series of terraces bounding a wide floodplain with a rich diversity of salmon habitats. By contrast, much of the Columbia River basin was not glaciated, and glacial outburst floods from Lake Missoula scoured the Columbia plateau and left deep silt deposits in several tributary basins, creating wide floodplains and groundwater-fed salmon habitats. These glacial histories constrain riverine habitat potential and genetic diversity of salmon in both basins, and also predispose each landscape to specific patterns of resource use. Since the mid-1800s, diking and ditching of floodplain and delta streams of the Skagit basin has obliterated more than 50% of salmon rearing habitat, but the arid Columbia basin has been most altered by construction of 18 large dams that produce hydropower and irrigate more than 2700 km (super 2) of former sagebrush steppe. We illustrate how intensive river management in both basins has shifted the riverscape away from diverse habitats maintained by natural disturbance regimes to simplified habitats and dampened disturbance regimes.

We present an integrated hydrologic-economic model that optimizes agricultural groundwater use next to streams with flow standards. Policies to meet instream flow standards should aim to minimize the welfare losses to irrigated agriculture due to reduced pumping. Previous economic studies have proposed spatially targeted water allocations between groundwater irrigators and instream demands. However, these studies focused on meeting aggregate instream flow goals on a seasonal or yearly basis rather than meeting them on a continuous basis. Temporally aggregated goals ignore important intra-seasonal hydrologic effects and may not provide sufficient habitat quality for species of concern. We present an optimization model that solves for groundwater pumping allocations across space in a stream-aquifer system with instream flow goals that must be met on a daily basis. We combine an analytical model of stream depletion with a farm profit maximization model that includes cumulative crop yield damages from water stress. The objective is the minimization of agricultural losses from reduced groundwater use while minimum instream flow requirements for ecological needs are met on a daily basis. As a case study, we apply our model to the Scott River basin in northern California. This is a region where stream depletion resulting from extensive irrigation has degraded habitat for Coho salmon, a species protected under the U.S. Endangered Species Act. Our results indicate the importance of considering the lag between the time at which pumping occurs and the time at which stream depletion related to that pumping occurs. In general, we find that wells located farther from the stream should be allocated more water in most hydrologic scenarios. However, we also find that the spatial and temporal distribution of optimal groundwater pumping can differ dramatically depending on the level of streamflow and instream flow targets. In particular, we find that in drought years wells located closer to the stream might be allocated more water than wells farther from the stream. This counterintuitive result is driven by spatial variability in the time lag associated with the stream depletion externality following pumping. Any period of time during the year with extreme water scarcity requires a cessation of pumping in advance of that period so that stream depletion impacts can adequately dissipate before the start of the period. Wells that are farther away from the stream cause higher stream depletion impacts following the cessation of pumping, so they may need to cease pumping earlier in advance of the period of extreme water scarcity. The analysis also suggests that in our case study area, the Scott River basin, policies that are spatially and temporally targeted may lead to welfare costs that are 30 percent less than welfare losses under uniform pumping restrictions. The relative welfare gains of the targeted policy over the uniform reduction policy increase as the scarcity of the instream water supply increases.

Daon is a small reararc seamount 25 km SW of Pagan (17 degrees 58'N). We visited the submarine portions of the two volcanoes in 2010 (NT10-12), using ROV Hyper-Dolphin and RV Natsushima. Rocks were collected from the northeastern and southwestern flanks of the Pagan volcano at 1,500-2,000 m b.s.l. (dive HPD1147) and at 2,020-2,330 m b.s.l. (HPD1148), respectively, and from the southern flank of Daon at 2,360-2,580 m b.s.l. (HPD1149). Fresh pillow lavas dominate in all three dives, but the rocks recovered from HPD1147 seem to be the youngest based on very light sediment cover and no Mn coating. Sediment cover is considerably more extensive at HPD1148, and all rocks from Daon (HPD1149) had 0-10 mm thick Mn coating. Submarine Pagan lavas show major element compositions typical of subaerial Pagan basalts (Marske et al., 2011; Elliott et al., 1997; Woodhead, 1989), although the least fractionated compositions recovered from HPD1147 extend to much higher MgO (7-11 wt%) and Mg# (60-70), than the subaerial lavas. We recognize two types of primitive basalts from Pagan and Daon. Daon has plagioclase-olivine basalt (POB) and clinopyroxene-olivine basalt (COB), petrographic types that are similar to those reported from NW Rota-1 volcano (Tamura et al., 2011). Pagan has two types of COB, both having 10-11 wt% MgO; COB-1 has higher Ba/Zr and Sr/Zr and lower Zr/Y than COB-2 at the same MgO content, indicating that COB-1 has a greater subduction component and formed from higher degrees of mantle melting than COB-2. Similar distinct primitive magmas like those recognized from NW Rota-1 also coexist at Pagan and Daon. References: Bloomer, S. H. et al. (1989). Bull Volcanol 51, 210-224. Elliott, T. et al. (1997).

The hypothesized cause of this event is the drainage of freshwater from proglacial Lake Agassiz through the Hudson Bay into the Labrador Sea, which may have slowed the Atlantic Meridional Overturning Circulation (AMOC) and affected climate. The climate system before the 8.2 ka event was generally similar to that of today with a few exceptions, including lower greenhouse gas concentrations, increased seasonality of insolation due to orbital forcing, a remnant of the Laurentide Ice Sheet near Hudson Bay and enhanced ice melt runoff down the St. Lawrence River. The catastrophic release of Lake Agassiz was followed by the melting and disintegration of the Laurentide Ice Sheet, adding a continued flux of freshwater to the North Atlantic over decadal to century time scale. Using realistic 8.5 ka boundary conditions in the Community Climate System Model version 3 (CCSM3), we have performed several freshwater forcing (FWF) experiments to simulate the 8.2 ka event. Freshwater was added over one year across the Labrador Sea and North Atlantic to simulate the lake drainage. Following the forcing, the system was allowed to recover uninterrupted. Experiments were also performed using estimates of the total freshwater flux (lake drainage plus ice melt) around 8.2 ka into the Labrador Sea to simulate the drainage of Lake Agassiz and subsequent collapse and disintegration of the Laurentide Ice Sheet. Results indicate a model response from the Lake Agassiz flood only that is shorter-lived and weaker than previously indicated by proxy records. The lake plus ice melt experiments show a response more consistent with proxy records. We, therefore, conclude that freshwater forcing in the form of meltwater from the Laurentide Ice Sheet following the drainage of Lake Agassiz is more important than the Lake Agassiz flood itself in causing a response in the CCSM3 that is comparable to paleo-proxy records of the 8.2 ka event in magnitude and duration.

In general, experiments show a consistently negative impact of acidification on coral calcification, leading to predictions of mass coral reef extinctions by dissolution as natural rates of carbonate erosion exceed the rates at which corals and other reef calcifiers can replace it. The tropical oceans provide a natural laboratory within which to test hypotheses about the longer term impact and adaptive potential of corals to acidification of the reef environment. Here we report results of a study in which 3-D CT scan and imaging techniques were used to quantify annual rates of calcification by conspecifics at 12 reefs sites spanning a natural gradient in ocean acidification. In situ Omega ar calculated from alkalinity and DIC measurements of reef seawater ranged from less than 2.7 on an eastern Pacific Reef to greater than 4.0 in the central Red Sea. No correlation between Omega ar and calcification was observed across this range. Corals living on low Omega ar reefs appear to be calcifying as fast, sometimes faster than conspecifics living on high Omega ar reefs. We used total lipid and tissue thickness to index the energetic status of colonies collected at each of our study sites. Our results support the hypothesis that energetics plays a key role in the coral calcification response to ocean acidification. Indeed, the true impact of acidification on coral reefs will likely be felt as temperatures rise and the ocean becomes more stratified, depleting coral energetic reserves through bleaching and reduced nutrient delivery to oceanic reefs.

The surface water temperature, partial pressure of carbon dioxide (pCO (sub 2sw) ), and aragonite saturation state (Omega (sub arag) ) of barrier reef waters were similar to those in the southern bay lagoon on seasonal and annual time scales. The pCO (sub 2sw) in Kaneohe Bay was higher in the summer than winter because temperature was also higher in summer. However, temperature and pCO (sub 2sw) have opposing effects on Omega (sub arag) which resulted in a lack of seasonality in Omega (sub arag) . Deeper southern bay lagoon waters had attenuated diel cycles compared to the shallow and biogeochemically active barrier reef. Photosynthesis and respiration controlled the diel cycles of Omega (sub arag) and pCO (sub 2sw) and resulted in large changes in both parameters on hourly time scales. The Omega (sub arag) levels in Kaneohe Bay were depressed, and pCO (sub 2sw) levels elevated, compared to levels in the open ocean and in other coral reef systems because of high net ecosystem calcification (NEC) rates. NEC produced enough CO (sub 2) to maintain high pCO (sub 2sw) levels while daily net photosynthesis consumed some CO (sub 2) . As demonstrated for Kaneohe Bay, the biogeochemical cycles occurring in coral reef ecosystems strongly alter the Omega (sub arag) and pCO (sub 2sw) of their open-ocean source waters. Taking into account the CO (sub 2) cycling within coral reef ecosystems may help determine which reefs will be negatively affected by ocean acidification in the near future.

The Tohoku, Japan tsunami of March 11, 2011 was an extreme event that continued to disturb the Pacific Ocean for many days following its initiation. Historically Japan was considered a source of low tsunami wave energy for the US West Coast. However, damage in California from the last great Japan tsunami was second to that suffered during the 1964 Alaska earthquake. Computer animations of the catastrophic Japan tsunami and other recent significant tsunamis combined with seismological techniques help to identify multiple paths of tsunami waves refracted and reflected by complex bathymetry across the Pacific Ocean basin. Using recent large tsunamigenic earthquakes we demonstrate that the long duration and damage noticed during the last great Japan tsunami in the farfield is a result of several factors. Waveguides acting as tsunami lenses and mirrors, including continental margins, direct the tsunami wave energy to diverse locations around the ocean basin; directionality affected by islands and seamounts, large reflections off of South America, bathymetric features far and near the area of impact and shelf geometry may delay and further amplify the main tsunami energy. This has direct implications on the prediction of tsunami impacts since the US West Coast appears to receive maximum waves much later than first wave arrivals.

This real-time estimation allowed NOAA Center for Tsunami Research (NCTR) to accurately provide experimental forecast of the tsunami impact for U.S. coastline in real time during the Japanese tsunami. It also led to quick, yet accurate, modeling of the tsunami inundation in Japanese coastline within hours after the event. The flooding limits computed with 11 inundation models that cover the entire east coastline of Japan agree well with observations. The computed tsunami runup height is up to 40 m, and the tsunami-height distribution along Japanese coastline is consistent with post-tsunami survey. These computational results will be compared with tsunami measurements and post-tsunami measurements, in light of a real-time tsunami source determined directly from deep-ocean tsunami measurements independent of any seismic data. Use of the forecast source scenario as input for tsunami inundation models for local coastlines shows promise for improved local tsunami forecast and warnings. The examples of the 2011 Japanese, as well as the 2010 Chilean, tsunamis will be used to illustrate the approaches to reducing the latency period for near-field tsunami forecasting. The catastrophic Japanese tsunami raised deep concerns about the tsunami impact in the U.S. Pacific Northwest (PNW), where a giant earthquake has been estimated to strike in the Cascadia within the next 50 years with a possibility of 10% to 15%. The similarity of tectonic settings and coastal environments between PNW and Sanriku, Japan may potentially result in comparable, or worse, disasters at PNW with what happened in Japan. To illustrate the similarity, we study the tsunami inundation impact along the coastline of PNW caused by a 500-year scenario on the Cascadia Subduction Zone (CSZ).

Comprehensive post-tsunami surveys and the availability of hundreds of videos within harbors and marinas allow for detailed documentation of these two events by the State of California Tsunami Program. Although neither event caused significant inundation of dry land in California because peak arrival occurred during low tide, damage to docks, harbor infrastructure, and boats was noteworthy. The 2010 Chile tsunami caused approximately $3-million in damage to a dozen harbors, primarily in central and southern California locations like Santa Cruz Harbor, Ventura Harbor and San Diego Bay. The 2011 Japan tsunami caused over $50-million in damage to more than two dozen harbors along the entire coast of California, most extensively to harbors/marinas in Crescent City, Noyo River, and Santa Cruz. During both events, strong tsunami currents, with some observed estimates greater than 15 knots, were generated at harbor entrances and along inside bends and narrows within harbors. Preliminary evaluations of harbor infrastructure and the interaction of boats indicate that drag along the base of large ships exacerbated the damage to docks to which the ships were tied. Evaluation of tsunami currents and damage will help in the validation/calibration of numerical tsunami model currents with the ultimate goal of developing tsunami current hazard maps for harbors statewide. These hazard maps will improve emergency response and infrastructure planning within harbors.

The revised Guide addresses the developments in the tsunami field since 1998, the need to accommodate vastly increased amounts of data, and to incorporate disciplines that were not covered in the original guide. The Guide also advocates a systems-approach to assessing tsunami impacts that examines the full range of physical, environmental, and socio-economic effects and their interrelationship, bringing tsunami research efforts into a closer alignment with the UN International Strategy for Disaster Reduction (UNISDR). This Field Guide is intended to provide a flexible framework to facilitate the acquisition of critical data in the immediate aftermath of significant tsunamis and to balance the needs of international researchers with those of communities and agencies involved with response and recovery. It will be of use to a variety of people and organizations who may either participate in, assist in coordination, or host post-tsunami field surveys. It is hoped that this Guide will promote pre-event planning in countries at risk of tsunamis to reduce the stresses of developing organizational logistics in the post-emergency response phase and make the process of conducting an ITST easier and more productive for both participating researchers and host country organizations. A complete draft of the Guide will be presented at the meeting and members of the tsunami community invited to comment.

These data sets were optimally combined through a truncated Stokes's kernel function (Li and Wang 2011). The final geoid model was obtained by harmonic downward continuation (Wang et al 2011). Overall, this leads to an 11.9 cm (rms) accuracy improvement over EGM2008 (Pavlis et al. 2008) at the local GPS-Leveling benchmarks (GPSBMs). For the next U.S. gravimetric geoid, USGG2012, the Alaskan geoid will also incorporate the new marine gravity model (DTU10, Andersen et al.) and gravity models from GOCE (GOCO02S, GOCO consortium). Residual terrain models (Forsberg 1984) for the high-frequency (5' to 3") geoid component, will also be included, both in Alaska and elsewhere.

Information critical to these decisions is needed for recently burned areas in the San Gabriel Mountains of southern California. A compilation of information on the hydrologic response to winter storms from recently burned areas in southern California steeplands is used to develop a system for classifying magnitudes of hydrologic response in this setting. The four-class system describes combinations of reported volumes of individual debris flows, consequences of debris flows and floods in an urban setting, and spatial extents of the hydrologic response. Magnitude 0 events show a negligible response, while Magnitude I events are characterized by small (10,000 m3) event. Several culverts or storm drains may be blocked or fail, several streets may be flooded or completely blocked by water and debris, and buildings, streets, and bridges may be damaged or destroyed. Magnitude III events consist of widespread and abundant debris flows of volumes >10,000 m3 and high discharge flooding causing significant impact to the built environment. Many streets, storm drains, and streets may be completely blocked by debris, making many streets unsafe for travel. Several large buildings, sections of infrastructure corridors and bridges may be damaged or destroyed. The range of rainfall conditions associated with different magnitude classes are defined by correlating local rainfall data with the response magnitude information. Magnitude 0 events can be expected when within-storm rainfall accumulations (A) of given durations (D) fall below the threshold A=0.4D0.5. Magnitude I events can be expected when storm rainfall conditions are above the threshold A=0.4D0.5 and below A=0.5D0.6 for durations greater than 1 hour. Magnitude II events will be generated in response to rainfall accumulations and durations between A=0.4D0.5 and A=0.9D0.5 for durations less than one hour, and between A=0.5D0.6 and A=0.9D0.5 for durations greater than one hour. Magnitude III events can be expected in response to rainfall conditions above the threshold A=0.9D 0.5. Rainfall threshold-magnitude relations are linked with potential emergency-response actions as an emergency-response decision chart, which leads a user through steps to determine potential event magnitudes and identify possible evacuation and resource-deployment levels. Use of this information in the planning and response decision-making process could result in increased safety for both the public and emergency responders.

The database includes all tsunami events, regardless of intensity, as well as earthquakes and volcanic eruptions that caused fatalities, moderate damage, or generated a tsunami. Event date, time, location, magnitude of the phenomenon, and socio-economic information are included in the database. Analysis of the NGDC event database reveals that the 21st century began with earthquakes in Gujarat, India (magnitude 7.7, 2001) and Bam, Iran (magnitude 6.6, 2003) that killed over 20,000 and 31,000 people, respectively. These numbers were dwarfed by the numbers of earthquake deaths in Pakistan (magnitude 7.6, 2005--86,000 deaths), Wenchuan, China (magnitude 7.9, 2008--87,652 deaths), and Haiti (magnitude 7.0, 2010--222,000 deaths). The Haiti event also ranks among the top ten most fatal earthquakes. The 21st century has observed the most fatal tsunami in recorded history--the 2004 magnitude 9.1 Sumatra earthquake and tsunami that caused over 227,000 deaths and $10 billion damage in 14 countries. Six years later, the 2011 Tohoku, Japan earthquake and tsunami, although not the most fatal (15,000 deaths and 5,000 missing), could cost Japan's government in excess of $300 billion--the most expensive tsunami in history. Volcanic eruptions can cause disruptions and economic impact to the airline industry, but due to their remote locations, fatalities and direct economic effects are uncommon. Despite this fact, the second most expensive eruption in recorded history occurred in the 21st century--the 2010 Merapi, Indonesia volcanic eruption that resulted in 324 deaths, 427 injuries, and $600 million in damage. NGDC integrates all natural hazard event datasets into one search interface. Users can find fatal tsunamis generated by earthquakes or volcanic eruptions. The user can then link to information about the related runup observations (e.g. maximum wave height) and the source earthquake or volcano. If available, damage photographs and plots of water level data can also be viewed. The data are accessible online via tables, reports, and a new state-of-the-art interactive map viewer. These data and access capabilities help coastal communities assess their risks, identify hazards, and promote public awareness of tsunamis and earthquakes.

After a destructive tsunami, international, national, and local tsunami scientists need to gather information, much of which is perishable or degrades significantly with time. An influx of researchers can put stress on countries already overwhelmed by humanitarian response to the disaster and by the demands of emergency management and other support agencies. In the United States, in addition to university research scientists, government agencies such as the National Oceanic and Atmospheric Administration (NOAA), the U.S. Geologic Survey (USGS), and state/territorial emergency management agencies and geological surveys endeavor to collect physical and social science data to better understand the physics of tsunamis and the impact they have on coastal communities and ecosystems. After a Presidential Major Disaster Declaration, the Federal Emergency Management Agency (FEMA) Joint Field Office works with state/territory emergency management agencies to coordinate response to disasters. In the short-term, the collection and immediate sharing of data enable decision-making that better organizes and deploys often-limited resources to the areas most critically in need of response; and in the long-term, improves recovery planning that will mitigate the losses from the next tsunami. Recent tsunamis have emphasized the need for improved coordination of data collection among scientists and federal, state, and local emergency managers. Improved coordination will ensure data collection efforts are carried out in a safe, secure, efficient, and timely manner. To improve coordination of activities that will better integrate the scientific investigations with government response, the US National Tsunami Hazard Mitigation Program and Pacific Risk Management 'Ohana (PRiMO) are working together to develop a consistent framework for a tsunami technical clearinghouse (TTC). The goals of the TTC, which would include at a minimum an electronic information server but could also include a physical location, are to: 1) assist in the response to, damage assessment of, and early recovery from the natural disaster; 2) facilitate researcher access to the affected areas; and 3) contribute to the capture of valuable and perishable data. The Working Group, composed of representatives from NOAA, USGS, FEMA, and state and local emergency managers and geoscientists, will engage with other stakeholders and the science community to review existing national standard operating procedures for post-tsunami scientific field surveys and data collection, as well as make recommendations for domestic application. The outcomes are intended to propose a national structure that can be consistently implemented within each state and territory.

The system relies on a numerical simulating code, MOST ("Method of Splitting Tsunami"), which is based on the theory of non-dispersive shallow water waves (SW). Studies indicate that due to the numerical dispersion inherent in its finite difference scheme, MOST may also be applied to the propagation of tsunamis with considerable frequency dispersive effects. In this study, we conduct a case study on the 2009 Samoa Tsunami to investigate the dispersive effects on tsunami oceanic propagation, and the application of MOST in simulating dispersive waves. Besides MOST, this event is also simulated with a weakly dispersive Boussinesq model, and an SW-type model solved through high-order finite difference scheme. This study shows significant dispersive effects in this event. The Boussinesq model has a good agreement with field measurements, while the high-order SW-type model predicts higher wave heights and earlier arrival times in most areas. By employing an optimized grid resolution, MOST provides accurate prediction at far less computational expense.

One of three NOAA data centers, NGDC hosts the long-term archive and management of tsunami data for research and mitigation of tsunami hazards under collaborative development between the National Weather Service, the Pacific Marine Environmental Laboratory, and the National Data Buoy Center. Archive responsibilities include the global historic tsunami event and run-up database, the Deep-ocean Assessment and Reporting of Tsunami (DART(Registered)) event and native bottom pressure and temperature observations, coastal tide-gauge data from US/NOAA operated stations, historic marigrams, and other hazards-related data and information. In terms of tsunami observations, NGDC currently process and archives all recovered native or 15 seconds high-resolution DART(Registered) bottom pressure observation time series. Tsunami signal-to-noise ratios in the deep-ocean are such that de-tiding based on a combination of tidal harmonic predictions and carefully constructed filters are necessary to obtain clean tsunami records. The processing includes removing tides using a customized version of the IOS tidal package of Mike Foreman. Additional processing is applied for parts of the records with registered tsunami events where the noise from the intra-gravity waves and components representing larger scale oceanic processes are removed by band-pass Kaiser-Bessel filters. The NGDC tsunami archive contains processed full record high-resolution observations for the period 2002-2010. An event-specific archive of real-time and native high-resolution observations recorded during recent significant tsunamis, including the March 2011 Japan Tohoku event are now available through new event pages that have been integrated with the NOAA Global Historical Tsunami Event Database. Event pages are developed to deliver comprehensive summaries of each tsunami event, including socio-economic impacts, tsunami travel time maps, raw observations, de-tided residuals, spectra of the tsunami signal compared to the energy of the background noise, and wavelets. These data are invaluable to tsunami researchers and educators as they are essential to providing a more thorough understanding of tsunamis and their propagation in the open ocean and subsequent inundation of coastal communities. All tsunami data are accessible at http://ngdc.noaa.gov/hazard/recenttsunamis.shtml. Details of filtering and tide removal techniques applied during the processing of all tsunami time series are discussed and spatial distribution and density of the observations along with general statistics are presented. Results obtained from analysis of all recently recovered 15-second high-resolution DART observations for the 11 March 2011 Japan Tohoku tsunami after application of the described processing techniques are presented and show the historic nature of this event; the largest deep-ocean tsunami amplitude in recorded history.

The OFCM working group for volcanic ash (WG/VA) has produced a national framework document entitled National Volcanic Ash Operations Plan for Aviation (NVOPA) in support of the International Airways Volcano Watch, August 2007. This document provides a high level look at the federal agency roles and responsibilities, products and services pertaining to volcanic ash. There are several regional plans that sit under the "national" plan framework specifically, Alaska Interagency Operating Plan for Volcanic Ash Episodes, July 2011; Interagency Operating Plan for Volcanic Ash Hazards to Aviation in the Pacific Region of the Northern Marianas Islands (draft framework), June 2009; Pacific Northwest (Washington/Oregon) Interagency Operating Plan for Volcanic Ash Events, May 2011. In addition to the plans listed above, there is a Hawaii volcano hazards and a California volcanic ash plan under development. Work on a Puerto Rico/Eastern Caribbean plan will commence in 2011. The purpose of these regional plans is to dovetail off of the NVOPA and provide more granularity with respect to agency roles and responsibilities. These regional plans often times will include agency call down lists and volcano specific information for the area of concern. The intent of these plans is not to act as an agency/office SOP but rather provide a more regional perspective. A side benefit to these plans is that they act as a focus around the development of table top exercises between the agencies. Areas in the continental U.S. that have relatively low frequency of volcanic events must practice through table top and communications exercises to remain proficient and ensure the messaging is communicated and appropriate action is taken in a timely fashion.

This area is susceptible to both near- and far-field tsunamis and has a historic record of damaging events. Crescent City Harbor, located about 100km north of Humboldt Bay, suffered $20 million in damages from strong currents produced by the 2006 Kuril Islands tsunami and an additional $16 million from the 2011 Tohoku-oki (Japan) tsunami. We deployed a Nortek Aquadopp 600kHz 2D Acoustic Doppler Current Profiler (ADCP) with a one-minute sampling interval in Humboldt Bay, near the NOAA tide gauge site. The instrument recorded the tsunami produced by the Mw 8.8 Chilean earthquake on February 27, 2010 as well as the Mw 9.0 Japanese earthquake on March 11, 2011. Currents from the 2010 tsunami persisted in Humboldt Bay for at least 30 hrs with a peak current amplitude of 0.3m/s. The 2011 tsunami signal lasted for over 86 hrs with a peak amplitude of 1.2m/s. Strongest currents corresponded to the maximum change in water level as recorded on the NOAA tide gauge, about 90 min after the initial wave arrival. Tsunami currents associated with ebb tides (tidal currents flowing out of the bay) were about 25% larger than currents associated with flood tides. No damage was observed in Humboldt Bay for either event; the 2011 tsunami pulled one boat away from its moorings at the marina about six kilometers away from the instrument site. Although we have no instrument in Crescent City, we were able to estimate currents for the first three and a half hours of the Japan tsunami using security camera video footage from the Harbor Master building across from the entrance to the boat basin, about 70m away from the NOAA tide gauge site. Most of the damage occurred within this time window. The strongest currents reached 4.5m/s and six cycles exceeded 4m/s in the three and a half hours of data. We used the MOST (Method of Splitting Tsunamis) model to compare measured currents to numerical predictions. MOST does a reasonably good job of predicting peak amplitudes for the 2010 and 2011 events in Humboldt Bay and the 2011 tsunami in Crescent City. For Humboldt Bay, the model does a good job of replicating the first four hours of the signal although the ebb currents are slightly underestimated. The model predictions break down for the later part of the signal. This project shows that ADCPs can effectively record tsunami currents for small to moderate events. Data from this project will be used to validate and/or calibrate MOST so that realistic tsunami current hazard maps can be generated for California for use by harbor managers.

Such a model would provide a common vertical reference system of orthometric heights accessed using GNSS technology. Canada and the U.S.A. already have plans to implement this for new national datums in 2013 (Canada) and 2022 (U.S.A.). The resulting geopotential values would also serve as the basis for determining dynamic heights as a part of the International Great Lakes Datum due to be updated around 2015. A critical aspect of this process then is the determining the most optimal geopotential value (W (sub 0) ) for these datum definitions. A number of different data sets were compared in this analysis including various geoid height models, GNSS-determined ellipsoidal coordinates on tidal bench marks (TBM's), models of mean ocean dynamic topography (MODT) determined from physical oceanography, and altimeter-derived mean sea surface heights (MSSH). The expectation of this analysis is that the geoid and MODT heights should equal the heights observed either at TBM's or in the MSSH models. The requirement that the MODT models be based on physical oceanography reduces potential correlation with the MSSH in the results. The aim of this study then was to evaluate independent data sets to determine uncorrelated and unambiguous results. Any biases would potentially indicate an incorrect choice of W (sub 0) . Current models of the U.S.A. and Canada use a W (sub 0) value of 62636856.88 m (super 2) /s (super 2) . The result of the comparisons show that this number is near optimal though some small change may be required depending pending refinement of the results along the eastern coast of the U.S.A., where the effects of the Gulf Stream complicate this analysis.

A Tsunami Warning is issued if the earthquake's magnitude exceeds a specific threshold level, and the epicenter is located within a region that could potentially generate a tsunami. Once a Warning has been disseminated, scientists at the West Coast/Alaska Tsunami Warning Center (WCATWC) begin to monitor tide gauges and DART buoys. This sea level information is then used to calibrate forecast models that compute the probable tsunami wave amplitudes at various locations along the coast. The observed sea level data, along with arrival time and coastal amplitude forecasts, are distributed to the appropriate government agencies. During a major event, the WCATWC will issue Warning or Advisory messages at frequency of 1 to 2 per hour. In addition, conference calls are conducted with State Emergency Managers every 1-2 hours to provide emergency managers more detailed information and an estimate of the time that the Warning or Advisory will remain in effect Estimating the length of time the Warning and Advisory would stay in effect proved difficult during the 2011 Japan Tsunami Warning. To address the problem, WCATWC developed a technique to estimate the time when the tsunami levels will fall below the Warning or Advisory thresholds. In many harbors along Alaska and the West Coast of North America the tsunami envelope will decay exponentially after the arrival of the maximum value. To estimate the time it will take before wave heights drop below Advisory levels the real time data is first filtered to remove the effects of tidal variations. A series of peaks occurring past the tsunami envelope peak are used to obtain a least squares fit to an exponential function. This method yields a decay constant which may be used to calculate the time that the wave height will fall below the advisory threshold of 0.3 meters. For example when this technique was applied to the Tohoku tsunami at Adak, Alaska, an accurate estimate of the time to the cancellation could be made 9.0 hours before the actual cancellation. Unfortunately, not all harbors demonstrate a uniform exponential decay. For these cases a series of exponential decay curves beginning at the envelope peak are superimposed on the real time tide data. An analyst can then monitor the sea level data and, with aid of the decay curves, obtain an estimated cancellation time for the event. This information may then be given to emergency managers during subsequent conference calls to assist with long range planning.

To date, tsunami risk reduction activities have been almost exclusively hazard mapping and evacuation planning. Reducing deaths in locations where evacuation to high ground is impossible in the short time between ground shaking and arrival of tsunamis requires measures such as vertical evacuation facilities or engineered pathways to safe ground. Yet, very few, if any, such tsunami mitigation projects have been done. In contrast, many tornado safe room and earthquake mitigation projects driven entirely or in largely by life safety have been done with costs in the billions of dollars. The absence of tsunami mitigation measures results from the belief that tsunamis are too infrequent and the costs too high to justify life safety mitigation measures. A simple analysis based on return periods, death rates, and the geographic distribution of high risk areas for these hazards demonstrates that this belief is incorrect: well-engineered tsunami mitigation projects are more cost-effective with higher benefit-cost ratios than almost all tornado or earthquake mitigation projects. Goldfinger's paleoseismic studies of CSZ turbidites indicate return periods for major CSZ tsunamis of about 250-500 years (USGS Prof. Paper 1661-F in press). Tsunami return periods are comparable to those for major earthquakes at a given location in high seismic areas and are much shorter than those for tornados at any location which range from >4,000 to >16,000 years for >EF2 and >EF4 tornadoes, respectively. The average earthquake death rate in the US over the past 100 years is about 1/year, or about 30/year including the 1906 San Francisco earthquake. The average death rate for tornadoes is about 90/year. For CSZ tsunamis, the estimated average death rate ranges from about 20/year (10,000 every 500 years) to 80/year (20,000 every 250 years). Thus, the long term deaths rates from tsunamis, earthquakes and tornadoes are comparable. High hazard areas for tornadoes and earthquakes cover approximately 40% and approximately 15% of the contiguous US, approximately 1,250,000 and approximately 500,000 square miles, respectively. In marked contrast, tsunami life safety risk is concentrated in communities with significant populations in areas where evacuation to high ground is impossible: probably <4,000 square miles or <0.1% of the US. The geographic distribution of life safety risk profoundly affects the economics of tsunami life safety mitigation projects. Consider a tsunami life safety project which saves an average of one life per year (500 lives per 500 years). Using FEMA's value of human life ($5.8 million), 7% discount rate and a 50-year project useful lifetime, the net present value of avoided deaths is $80 million. Thus, the benefit-cost ratio would be about 16 or about 80 for tsunami mitigation projects which cost $5 million or $1 million, respectively. These rough calculations indicate that tsunami mitigation projects in high risk locations are economically justified. More importantly, these results indicate that national and local priorities for natural hazard mitigation should be reconsidered, with tsunami mitigation given a very high priority.

At Axial Seamount, an active deep-sea volcano located on the Juan de Fuca Ridge, sulfide concentrations have been measured as high as 5770 mu M, and sulfide oxidation is quantitatively the most important chemical energy source for microbial metabolism. In addition, studies of microbial population structure indicate that diffuse fluids at Axial are dominated by putative sulfur- and sulfide-oxidizing bacteria belonging to the Epsilonproteobacteria. To further study this important microbial process, we surveyed diffuse vent samples from Axial over a range of temperature, pH, and sulfide concentrations for the presence and expression of sulfide-oxidizing bacteria using a functional gene approach. Dissolved oxygen concentrations decrease exponentially above 40 degrees C and lower the potential for sulfide oxidation, so we identified six sites of different temperatures, two each in the low (< 30 degrees C), medium ( approximately 30 degrees C), and high temperature (30-50 degrees C) range. The low temperature sites had sulfide-to-temperature ratios of 1-26, the medium from 15-29, and the high from 26-36. PCR primers were designed to target the sulfur oxidation gene soxB specifically from Epsilonproteobacteria and five of the six sites were positive for soxB in the DNA fraction. Bulk RNA was also extracted from the same sites to examine in situ expression of soxB. Data from these analyses, along with quantification of the soxB gene abundance and expression using quantitative PCR, are currently being carried out. Together, this data set of soxB gene diversity, expression, and abundance along with geochemical data will allow us to quantitatively determine the functional dynamics of sulfide oxidation in the subseafloor at Axial Seamount. The molecular techniques developed in this project are also being applied to fluid samples collected from many of the same sites at Axial following the recent 2011 eruption, as well as fluid samples collected from new snowblower vents believed to be rich in sulfide-oxidizing bacteria.

In SIFT, tsunami simulations for about 1600 individual earthquake sources, each 100 X 50 km, define shallow subduction worldwide. These simulations are stored in a database and combined linearly to make up the tsunami from any great earthquake. Precomputation is necessary because the nonlinear shallow-water wave equations are too time consuming to compute during an event. While such scenario-based models are valuable, they tacitly assume all energy in a tsunami comes from thrust at the decollement. The thrust assumption is often violated (e.g., 1933 Sanriku, 2007 Kurils, 2009 Samoa), while a significant number of tsunamigenic earthquakes are completely unrelated to subduction (e.g., 1812 Santa Barbara, 1939 Accra, 1975 Kalapana). Finally, parts of some subduction zones are so poorly defined that precomputations may be of little value (e.g., 1762 Arakan, 1755 Lisbon). For all such sources, a fast means of estimating tsunami size is essential. At the Pacific Tsunami Warning Center, we have been using our model RIFT (Real-time Inundation Forecasting of Tsunamis) experimentally for two years. RIFT is fast by design: it solves only the linearized form of the equations. At 4 arc-minutes resolution calculations for the entire Pacific take just a few minutes on an 8-processor Linux box. Part of the rationale for developing RIFT was earthquakes of M 7.8 or smaller, which approach the lower limit of the more complex SIFT's abilities. For such events we currently issue a fixed warning to areas within 1,000 km of the source, which typically means a lot of over-warning. With sources defined by W-phase CMTs, exhaustive comparison with runup data shows that we can reduce the warning area significantly. Even before CMTs are available, we routinely run models based on the local tectonics, which provide a useful first estimate of the tsunami. Our runup comparisons show that Green's Law (i.e., 1-D runup estimates) works very well indeed, especially if computations are run at 2 arc-minutes. We are developing an experimental RIFT-based product showing expected runups on open coasts. While these will necessarily be rather crude they will be a great help to emergency managers trying to assess the hazard. RIFT is typically run using a single source, but it can already handle multiple sources. In particular, it can handle multiple sources of different orientations such as 1993 Okushiri, or the decollement-splay combinations to be expected during major earthquakes in accretionary margins such as Nankai, Cascadia, and Middle America. As computers get faster and the number-crunching burden is off-loaded to GPUs, we are convinced there will still be a use for a fast, linearized, modeling capability. Rather than applying scaling laws to a CMT, or distributing slip over 100 X 50 km sub-faults, for example, it would be preferable to model tsunamis using the output from a finite-fault analysis. To accomplish such a compute-bound task fast enough for warning purposes will demand a rapid, approximate technique like RIFT.

Forty day time series of vertical velocity and temperature fluctuations were obtained across the rising plume at 20 m above the Dante edifice in an environment where the flow is dominated by strong (5 cm s (super -1) ) semi-diurnal tidal currents and a northerly mean residual flow (3 cm s (super -1) ). These measurements provide a window on deep-sea hydrothermal plume dynamics in strong oscillatory cross flows. Plume models that take into account ambient stratification and time-dependent background flows, in conjunction with these measurements, yield insights into entrainment, plume bending, rise height, and, inferentially, mound heat flux. In particular, an integral plume model with an entrainment velocity that is a function of both the plume axial velocity and the ambient tidal flow perpendicular to the plume axis indicates that increased entrainment occurs during strong cross flows causing the plume to cool, rise more slowly and bend. Results from a separate three-dimensional numerical model show the plume bending with the tidal cycle and having rise heights that vary from approximately 75 to approximately 250 m for an estimated mound heat flux of 40MW and a discharge salinity anomaly of -5 psu. The model attributes the observed inverse relationship of plume vertical and background horizontal velocities to the plume's bending by tidal currents as well.

This speed difference allows TWC scientists to determine the tsunami-generating potential of an earthquake, or even analyze the tsunami itself, before the tsunami reaches threatened coastlines. Given that we know where tsunami-generating earthquakes are likely to occur, how fast both seismic and tsunami waves propagate, and the distribution of both seismic and sea-level sensors installed around the world, we can predict how rapidly a TWC should be able to respond to any tsunami-generating earthquake and thus which coastlines will receive a tsunami warning in time to react and which coastlines will get little or no warning (Becker et al., EOS Trans. AGU, 2010). TWCs can forecast a tsunami and issue a warning based on earthquake characteristics alone, but near real-time sea-level measurements are necessary for the TWC to refine its forecast and expand, narrow, or cancel tsunami warnings, to not only protect more lives and property when a tsunami is more severe than initially forecast, but to also prevent unnecessary and costly evacuations when a tsunami is less intense and/or more focused than initially forecast. To determine how soon a TWC will have useful sea-level data after an earthquake, we calculated tsunami travel times (TTTs) from likely tsunami sources, i.e., thrust faults at subduction zones, to both coastal and deep-ocean sea level sensors monitored by the Pacific Tsunami Warning Center (PTWC). For this purpose we geographically sampled the axes of deep-sea trenches with a geodesic grid to ensure equal spacing of simulated sources. We then calculated global TTT grids for each of these sources and sampled each grid at the locations of coastal and deep-ocean sea-level gauges currently monitored by the Pacific Tsunami Warning Center (PTWC). We then added each gauge's transmission interval to the TTT values sampled at the gauges to determine the maximum time required for one, two, and three gauges to detect and transmit information about a tsunami generated by these sources. We also analyzed the network available to PTWC in 2005, showing how detection times have improved since then, and a hypothetical network in which all coastlines and oceans are saturated with sensors, showing that further improvements are still possible. We also used these data to quantify how the network can be compromised by sensor outages, identify those tsunami sources most in need of additional sea-level sensors for tsunami detection, and determine where future sensors should be located. As installing one deep-ocean sensor costs about 10 times as much as installing a coastal gauge, we also determine which sensor is more cost-effective for filling these network gaps. These analyses show that for global tsunami hazard mitigation the installation of about 100 additional carefully-selected coastal sea-level gauges could greatly improve the speed of tsunami detection and characterization.

Continuous monitoring of CO (sub 2) flux has been achieved in only a few instances at subaerial volcanoes, but never for submarine volcanoes. Here we use the first sustained (year-long) hydroacoustic monitoring of an erupting submarine volcano (NW Rota-1, Mariana island arc) to make the first calculations of total gas flux from a volcano into the ocean. Bursts of Strombolian explosive degassing at the volcano summit (520 m deep) occurred at 1-2 minute intervals during the entire 12-month hydrophone record and commonly exhibited cyclic step-function changes between high and low intensity. The explosion bursts are comprised of hundreds of individual (100-200 ms duration) explosion pulses totaling approximately 12.7M discrete pulses recorded during the year. The acoustic explosion packets are broadband: 1-80 Hz with a peak at 30 Hz. The loudest explosions occurred during February-August 2008 with a typical sound level of 192 dB (sub rms) re mu Pa (super 2) /Hz [at] 1m, equal to approximately 100 W of acoustic power. Total gas flux calculated from the hydroacoustic record, 5.4 + or - 0.6 Tg a (super -1) , combined with melt inclusion information, yields an annual CO (sub 2) eruption flux of 0.4 + or - 0.1 Tg a (super -1) . This result is consistent with measured CO (sub 2) fluxes at continuously erupting subaerial volcanoes ( approximately 0.5 Tg a (super -1) ), and represents approximately 0.2-0.6% of the annual estimated output of CO (sub 2) from all subaerial arc volcanoes. The multi-year eruptive history of NW Rota-1 demonstrates that submarine volcanoes can be significant and sustained sources of CO (sub 2) to the shallow ocean.

The NE portion of this basin is characterized by numerous recently active volcanic centers that have erupted a diverse range of magma types over a relatively small spatial domain (see Embley et al., 2009, abstract V51D-1719). Roughly 20% of the sea floor in an area of 40 X 70km in the northeasternmost portion of the basin is floored by high backscatter seafloor characterized by little to no sediment cover, as documented by near-bottom photographs, and recovery of relatively fresh lavas during dredging operations aboard the R/V Kilo Moana in 2010. Visual observations are consistent with ages of 100 to 1000 yrs for most of these lavas. This region includes two recently active volcanoes discovered in 2008 as well as numerous others, such as a series of 9 small, very closely spaced, hydrothermally-active, elongate volcanic edifices (the "Matas") near the east-west portion of the Tonga Trench with an average spacing of just 4 km between the summits. Dredging reveals that all the Matas are composed of fresh boninite or picrite. A large, approximately 140 km (super 2) lava sheet composed of one or more lava flows emanates from ridges and scarps between Volcano "O" and West Mata. These predominantly lobate and pillowed flows are fresh, very glassy and nearly aphyric; given lava thicknesses in excess of 30m seen in collapsed lava ponds, total erupted volumes probably represent >4 km (super 3) of erupted magma. Other features in the area, some of which are currently hydrothermally active, have erupted compositions ranging from basalt to dacite. The voluminous, geologically recent volcanic activity from a wide range of primarily extensional volcanic centers suggests that this portion of the highly dynamic NE Lau Basin is experiencing chaotic and perhaps transient patterns of localized mantle upwelling capable of sampling and preserving a diverse range of mantle compositions and magma-forming conditions. The defocused nature of the volcanism is likely aided by neotectonic activity producing tears in the thin lithosphere of the basin. Lava whole rock compositions and preliminary U-series disequilibria data suggest that magmas are forming here at rates comparable to the fast-spreading East Pacific Rise and with limited residence time in crustal magma bodies. Collectively, these observations suggest rapid melting and melt transport over a wide area of shallow back arc mantle with highly localized zones of upwelling and melt focusing to multiple simultaneously active volcanic centers, and that significant back arc magmatism occurs at non-spreading center volcanoes.

The number of eruptions detected and responded to remain very few, however, so our knowledge of the magnitude and rate of crust-ocean interaction at the instant of an eruption is almost entirely circumstantial. The discovery of uniquely different plumes over a 2008 eruption on the NE Lau spreading center greatly broadened the known range of eruption-initiated transfer of heat, chemicals, and perhaps biota from the crust to the ocean. Serendipitous observations and rapid response cruises have now documented that the "event (mega-) plumes" accompanying eruptions range over a factor of 100 in volume (1-150 km (super 3) ), yet maintain a distinctive and consistent chemical signature (much lower (super 3) He/heat and Mn/heat and higher H (sub 2) /heat than typical black smokers). Confirmed event plumes have formed at spreading rates from 55- approximately 90 mm/yr, with some incompletely sampled but "event-like" plumes observed at even slower rates (11-30 mm/yr; Gakkel and Carlsberg Ridges). Presently, only four event plumes can be associated with specific eruptions. Large event plumes in the NE Pacific were found over thick (up to approximately 75 m), voluminous, and slowly extruded pillow mounds. The 2008 eruption on the fast-spreading NE Lau spreading center demonstrated that thin (a few meters), small, and rapidly emplaced sheet flows can generate smaller event plumes. Available evidence suggests that massive fluid discharge occurs virtually simultaneously with an eruption. At Gorda Ridge in 1996, eruption-indicative seismicity began on the same day and location an event plume was found. At Axial Volcano in 1998, moorings 2 km apart both recorded the appearance of a >100-m-thick plume within minutes of the start of a 72-min-long sheet flow eruption. These observations support inferences from plume modeling and chemistry that event plume generation time is hours, not days. Candidates for the source of event plume fluids include the release of high-temperature, pre-formed hydrothermal fluid from the crust or magma chamber; the heating of crustal fluid by a cooling dike; or the conversion of seawater to hydrothermal fluid by cooling lava. The requirements of very high crustal permeabilities and/or a large volume of stored fluids hinder the first two hypotheses. The slow rate of lava cooling relative to event plume formation hinders the third hypothesis. Whatever the process, the uniform and unique chemistry of event plumes requires a consistent formation process during all types and sizes of eruptions. High concentrations of H (sub 2) and abundant basalt shards in the 2008 event plumes necessitate interaction between source fluids and molten lava. The 2008 observations also preclude source fluid salinities < approximately 15 psu, much higher than the values as low as approximately 2 psu measured in post-eruption vent fluids at some sites. Source fluids with salinities fresher than approximately 15 psu would have produced unreasonably high or negative temperature anomaly values in the event plumes. The immediate generation of copious hydrothermal fluids now seems a common consequence of any midocean ridge eruption at any depth. The difficulty of formulating a convincing theory to explain this conclusion implies that we remain ignorant about some of the most fundamental processes that occur during events of ocean crust accretion.

The VAA contains information about which volcano is erupting, the volcanoes location, as well as the time and duration of the eruption. If ash is observed in satellite imagery, a 6, 12 and 18 hour forecast are provided to specify the possible location of ash. The goal of the VAA is to help airlines create accurate flight guidance for their aircraft. The priority of each VAAC is to prevent aircraft from flying through ash with a secondary priority of minimizing unnecessary diversions. Remote sensing platforms provide a unique perspective for volcanic ash detection especially in the cases of remote and unmonitored volcanoes. This includes monitoring of multispectral satellite imagery (Visible, Infrared) from both geostationary and polar orbiting platforms as well as derived products such as SO (sub 2) , Volcanic Ash Masks/Loading and LIDAR data. To generate the VAA, satellite analysts use the satellite imagery in combination with observations from local Meteorological Watch Offices (MWO), Volcano Observatories, Pilot Reports (PIREP), seismic stations, web cameras and meteorological forecast grids. Challenges arise in regard to availability of data for each individual volcano, reliability of model wind fields over data sparse regions, as well as timeliness and availability of satellite imagery and products. These challenges become further exacerbated when volcanic ash crosses VAAC and MWO boundaries and interagency communication becomes essential. While working through multi-lingual communications and operational variation (e.g. data availability, standard operation procedures), VAACs face the challenge of maintaining coordination and avoiding the pitfalls of break downs in communication and guidance confusion. This talk will discuss these issues and pose potential communication and coordination efforts from the Washington VAAC perspective.

The NE Lau basin has the highest subduction rates on Earth [Bevis et al., 1995] and is Earth's fastest-opening back-arc basin [Zellmer and Taylor, 2001]. The NE Lau Basin contains abundant recent submarine volcanism with magma production likely driven by water released from the subducting slab and decompression associated with crustal extension. One manifestation of this abundant volcanism is Volcano O, one of the largest discrete active-submarine volcanoes on Earth. It is hard to classify this volcano is either arc or back arc because its location behind the magmatic arc is inconsistent with the eruption of dacitic lavas and highly acidic hydrothermal activity reported here. Volcano O has exhibited ongoing hydrothermal activity as documented in 2004 (Lupton pers. Comm.), 2006 [Kim et al., 2009], and in both 2008 and 2010 as presented here. In 2008 and 2010, we documented intense hydrothermal plumes in several locations in the caldera. The most intense hydrothermal plume was observed in 2010 directly above a small cone on the eastern side of the caldera. A camera tow across the cone revealed fresh blocky lavas with a hint of sulfur-rich waters surrounding the cone. Here we present data on the chemistry of hydrothermal plumes at Volcano O. Of particular interest is a hydrocast conducted directly above the cone. During this hydrocast we collected fluids rich in Fe (< or =13,000nM), Mn (< or =665nM), particulate Al (< or =1500nM), particulate sulfur (< or =18000nM), and with large decreases in pH (< or =0.9 pH units). These anomalies are extraordinarily large and are much greater than the Fe and Mn levels observed by Kim et al. These chemical enrichments and depletions strongly suggest that Volcano O is actively degassing SO (sub 2) which, in turn, suggests that the magma chamber must be fairly shallow. This may indicate an active state of cone building at Volcano O. In addition to the above data, we will also present data on CO (sub 2) and (super 3) He in the plumes to better constrain the source of the magmatic volatiles feeding the volcano.

Because groundwater often has elevated nutrient levels with respect to surface water, submarine groundwater discharge (SGD) may be an important source of nutrients to coastal bays. To understand the pathways of SGD and how bayfloor geology and hydrology affect them, we examined the geology, porewater salinity, and SGD rates and patterns at Indian River Bay, DE. Marine geophysical tools were used to identify the hydrogeologic framework and geometry of a shore-perpendicular freshwater plume beneath the bay. Shallow chirp seismic data outlined a low-permeability paleochannel infill, which is 150 m across and 2-3m thick at the center, thinning towards the channel flanks. Offshore continuous resistivity profiling (CRP) data show a low-salinity plume generally co-located with, but extending beyond the edges of, this low-permeability cap. Salinity data from 12 offshore wells with multi-level sampling ports verify the general extent of the plume indicated by CRP data. Using Lee-type seepage meters, 565 direct measurements of SGD were made between July 2010 and June 2011. These data show that the paleochannel feature generally controls nearby fresh SGD (FSGD), preventing discharge at the shoreline and causing diffuse freshened or brackish discharge at the channel flanks. In the adjoining interfluve, where the low-K cap is absent, fresh discharge appears focused and decreases monotonically from the shoreline, as predicted by theory. Saline SGD did not follow this trend and comprised the majority of the discharge. The measured maximum FSGD was 33 cm/d compared to 198 cm/d for recirculated baywater. SGD salinity ranged from 0-33 ppt, with an average of 26.9 ppt; the average surface baywater salinity was 28.4 ppt. Seepage salinity patterns correlate spatially with CRP survey results. To assess the potential for saline SGD driven by interactions of surface water flowing over deployed seepage meters, bay surface current velocities were measured with an acoustic Doppler current profiler. Currents ranged from 0-20 cm/s with an average of 3-6 cm/s, which would produce an estimated discharge of <6 cm/d, less than the average measured saline flux (9.2 cm/d). This indicates that other factors are driving the large saline SGD component at this site. During spring tides, both fresh and saline SGD rates at low tide are twice those at high tide, indicating a strong tidal influence on SGD. Though SGD is difficult to measure due to inherent geologic heterogeneity, temporal forcing factors and current/bathymetry interactions, extensive direct seepage data and correlated geophysical and well data show that the low-permeability paleochannel cap confines and controls fresh and saline groundwater flowpaths to the bay. By quantifying the effects of this cap we can develop better estimates of water and chemical fluxes into the bay.

A danger, however, is that the processes observed at a particular research watershed are too specific to the watershed and not representative even of the larger scale watershed that contains that particular research watershed. Thus, models developed based on those partial observations may not be suitable for general hydrologic use. Therefore demonstrating the upscaling of hydrologic process from research watersheds to larger watersheds is essential to validate concepts and test model structure. The Hydrograph model has been developed as a general-purpose process-based hydrologic distributed system. In its applications and further development we evaluate the scaling of model concepts and parameters in a wide range of hydrologic landscapes. All models, either lumped or distributed, are based on a discretization concept. It is common practice that watersheds are discretized into so called hydrologic units or hydrologic landscapes possessing assumed homogeneous hydrologic functioning. If a model structure is fixed, the difference in hydrologic functioning (difference in hydrologic landscapes) should be reflected by a specific set of model parameters. Research watersheds provide the possibility for reasonable detailed combining of processes into some typical hydrologic concept such as hydrologic units, hydrologic forms, and runoff formation complexes in the Hydrograph model. And here by upscaling we imply not the upscaling of a single process but upscaling of such unified hydrologic functioning. The simulation of runoff processes for the Dry Creek research watershed, Idaho, USA (27 km2) was undertaken using the Hydrograph model. The information on the watershed was provided by Boise State University and included a GIS database of watershed characteristics and a detailed hydrometeorological observational dataset. The model provided good simulation results in terms of runoff and variable states of soil and snow over a simulation period 2000 - 2009. The parameters of the model were hand-adjusted based on rational sense, observational data and available understanding of underlying processes. For the first run some processes as riparian vegetation impact on runoff and streamflow/groundwater interaction were handled in a conceptual way. It was shown that the use of Hydrograph model which requires modest amount of parameter calibration may serve also as a quality control for observations. Based on the obtained parameters values and process understanding at the research watershed the model was applied to the larger scale watersheds located in similar environment - the Boise River at South Fork (1660 km2) and Twin Springs (2155 km2). The evaluation of the results of such upscaling will be presented.

Increases in evapotranspiration from earlier exposure of vegetation and soils decreases annual runoff by more than 1.0 billion cubic meters or approximately 5% of the annual average. This prior work was based on observed dust loadings during 2003-2008, however 2009 and 2010 saw unprecedented levels of dust loading on snowpacks in the Upper Colorado River basin on the order of 5 times the 2003-2008 loading. We present new results examining the hydrologic impact of extreme dust years such as 2009/2010, and interactions with projected regional warming.

These high-precision observations offer key constraints on CH (sub 4) 's budget including the global burden, the rate of increase, and the spatial distribution of CH (sub 4) at the surface. These observations allow estimates of total global CH (sub 4) emissions without using a chemical transport model. A surprising result of this analysis is that, if the CH (sub 4) lifetime has been constant, then total global emissions have been approximately constant since the mid-1980s. This result is difficult to reconcile with bottom-up inventories that report increasing anthropogenic emissions, unless natural emissions have decreased considerably. Analysis of anomalies in CH (sub 4) growth rate also allow us to test our understanding of the processes that affect the atmospheric CH (sub 4) burden. Large anomalies have been attributed to decreased CH (sub 4) sink after the eruption of Mt. Pinatubo in 1992, decreased emissions from wetlands because of cooler than normal temperatures in 1992, and increased emissions from biomass burning and wetlands in 1997/98. The most recent anomaly, starting in 2007 and continuing into early-2011 with an average rate of increase of nearly equal 6 ppb yr (super -1) , is more persistent than previous ones and may indicate a permanent change to the global CH (sub 4) budget. Dlugokencky et al. [Geophys. Res. Lett., 36, 2009] attributed the increases in 2007 and 2008 to anomalously high temperatures in the Arctic (2007) and greater than average precipitation in the tropics (2007 and 2008). Continuing increases in 2009 and 2010 may be related to a very strong La Nina starting in 2010, the same climate pattern responsible for large positive precipitation anomalies in tropical wetland regions in 2007 and 2008. Indeed, strong precipitation anomalies were observed in SE Asia during 2010. This is a likely cause of continued CH (sub 4) increase, and it is consistent with the observation that the largest growth rates in 2010 were in the southern tropics. For 2009, when we were in a weak El Nino, no clear cause has emerged. The observations indicate the largest growth rates were observed in mid-latitudes of the northern hemisphere, a departure from 2007, 2008, and 2010 when signals were clearly dominated by the tropics. A recent model study by Bousquet et al. (Atmos. Chem. Phys., 11, 3689-3700, 2011) is consistent with our earlier study on the role of tropical and high northern latitude wetlands in increased CH (sub 4) growth during 2007, but unclear as to the causes of increase in 2008. Little additional information about the causes of the recent anomaly has been determined from satellite retrievals of CH (sub 4) column abundance (Frankenberg et al., J. Geophys. Res., 116, 2011).

A new global inventory of dust sources is derived from Aqua MODIS Deep Blue Level 2 spectral aerosol data, after evaluation with ground based AERONET sunphotometers data. The natural or anthropogenic origin of the sources is attributed from land use, land cover and hydrological datasets. Comparison with data from other instruments (e.g. TOMS, OMI, SEAWiFS, MODIS on Terra) show remarkable similarities over most natural sources. The regional differences are essentially related to the combination of drought and land use. Simulations of natural and anthropogenic dust with the NOAA-GFDL AM3 climate model allow to quantify their respective contribution to aerosol optical depth, absorption optical depth and radiative forcing.

On the other hand, the additional of billions of tons of greenhouse gases in the atmosphere due to permafrost thawing will intensify the global warming. We investigate the interaction of permafrost thawing and global warming and estimate the surface warming due to permafrost carbon release during period of 1960-2200. We use SiBCASA (land surface model) projections based on A1B scenario to obtain the cumulative permafrost carbon flux to atmosphere, calculate the corresponding increase in atmospheric CO2 concentration and add it to the CO2 concentration of A1B scenario. We will use the PLASIM (General Climate Model) to estimate the additional increase in surface air temperature due to permafrost thawing in 21st and 22nd Century. Our SibCASA projections indicated a cumulative permafrost carbon release of 190+ or -64 Gt by 2200, which is equivalent to an increase in atmospheric CO2 concentration of 87+ or -29 ppm. Based on the Vostok record, an increase of nearly equal 80 ppm is associated with 8-10 degrees C increase in global temperature after glacial termination, so strong surface warming due to permafrost thawing is expected.

Emissions from carbon stored in Arctic soil are projected to increase as the region warms and the permafrost thaws, creating a potent feedback mechanism for climate change. This year, NASA's Carbon in Arctic Reservoirs Vulnerability Experiment (CARVE) began multi-year aircraft measurements in Alaska, which, coupled with regional modeling of methane fluxes, will evaluate and quantify the effect of regional climate change on ecosystem CO2 and CH4 fluxes. A crucial component of such regional modeling is the choice of background mixing ratio for a given atmospheric sample. A recent addition to the NOAA/GMD aircraft program provides valuable information on background mixing ratios for the Alaskan interior and provides insight into the seasonal cycle and inter-annual variability as well as spatial and temporal context for the measurements being made during the CARVE campaigns. The NOAA/GMD aircraft program began new, ongoing greenhouse gas measurements in Alaska in 2009 (complementing existing ground stations at Barrow and Cold Bay, and a flask-only aircraft site outside of Fairbanks), through a collaboration with the U.S. Coast Guard. Bi-weekly Arctic Domain Awareness flights on C-130 aircraft generally begin in Kodiak, continue to Barrow, and return back to Kodiak after altitude profiles over Kivalina and Galena. On-board measurements include continuous CO2, CH4, CO, and ozone, as well as 24 flask samples analyzed at NOAA for CO2, CH4, CO, and 50 additional gases. In addition to spanning a large geographic region, the measurements also span the entire growing season, from late March to late November each year. We will present data from 2009 - 2011, with a focus on Arctic CH4. The measurements provide us with additional understanding of the various influences on the seasonal cycles of CH4 and CO2: stratospheric mixing, transport from lower latitudes, and boundary layer processes. They also provide an assessment of potential regional sources of CH4, such as those that may exist in the Arctic Ocean. Our measurements are a valuable tool for regional Arctic modeling efforts seeking to validate boundary conditions from global models, such as CarbonTracker-CH4, and contribute to scientific knowledge of CH4 emissions in the high northern latitudes.

G. Roble advanced an ambitious program of developing an atmospheric general circulation model (GCM) extending from the surface to the exosphere. He outlined several areas of research and application to potentially benefit from what is now commonly called whole atmosphere modeling. The purpose of this article is to introduce this new field to a broader geophysical community and document its progress over the last decade. Vertically extended models are commonly built from existing weather and climate GCM codes incorporating a number of approximations, which may no longer be valid. Promising directions of further model development, potential applications, and challenges are outlined. One application is space weather or day-to-day and seasonal variability in the ionosphere and thermosphere driven by meteorological processes from below. Various modes of connection between the lower and upper atmosphere had been known before, but new and sometimes unexpected observational evidence has emerged over the last decade. Persistent "nonmigrating" wavy structures in plasma and neutral densities and a dramatic response of the equatorial ionosphere to sudden warmings in the polar winter stratosphere are just two examples. Because large-scale meteorological processes are predictable several days in advance, whole atmosphere weather prediction models open an opportunity for developing a real forecast capability for space weather. Key Points * Progress in a new actively developing area of research is documented * Whole atmosphere models promise a forecast capability for space weather * Whole atmosphere models may be beneficial for conventional weather prediction JF - Reviews of Geophysics AU - Akmaev, R A AD - NOAA Space Weather Prediction Center, Boulder, Colorado, USA.

Scientific use of data from the Swarm mission will also benefit significantly from derived products, the so-called Level-2 products, that take into account the features of the constellation. For this reason ESA has established a "Satellite Constellation Application and Research Facility" (SCARF), in the form of a consortium of several research institutions. A number of Level-2 data products will be offered by this consortium, including various models of the core and lithospheric field, as well as of the ionospheric and magnetospheric field. In addition, derived parameters like mantle conductivity, thermospheric mass density and winds, field-aligned currents, an ionospheric plasma bubble index, the ionospheric total electron content and the dayside equatorial zonal electrical field will be calculated.

The paleo index is compiled from 117 temperature-sensitive proxy records including corals, ice cores, lake and ocean sediments, and historical documents. The individual series are globally-distributed with inter-annual to sub-annual resolution. Each series was normalized to produce index values of change relative to a 1901-2000 base period; the index values were then averaged. From 1880 to 1995, the index trends significantly upward, similar to the GST. Small-scale aspects of the GST including two warming trends and a warm interval during the 1940s are also observed in the paleo index. The paleo index continuously extends back to 1730 with 45 records and reveals that the upward trend observed in the GST began in the early 19th century. The paleo index supports the fidelity of the GST and confirms the global extent of the warming trend of the past century.

Current hypotheses used to explain these lake level changes include the thermodynamic hypothesis, in which decreased tropospheric water vapor coupled with patterns of convergence and divergence caused dry areas to become more wet and vice versa, the dynamic hypothesis, in which shifts in the jet stream and Inter-Tropical Convergence Zone (ITCZ) altered precipitation patterns, and the evaporation hypothesis, in which lake expansions are attributed to reduced evaporation in a colder climate. This modeling study uses the output of four climate models participating in phase 2 of the Paleoclimate Modeling Intercomparison Project (PMIP2) as input into a lake energy-balance model, in order to test the accuracy of the models and understand the causes of lake level changes. We model five lakes which include the Great Basin lakes, USA; Lake Peten Itza, Guatemala; Lake Caco, northern Brazil; Lake Tauca (Titicaca), Bolivia and Peru; and Lake Cari-Laufquen, Argentina. These lakes create a transect through the drylands of North America through the tropics and to the drylands of South America. The models accurately recreate LGM conditions in 14 out of 20 simulations, with the Great Basin lakes being the most robust and Lake Caco being the least robust, due to model biases in portraying the ITCZ over South America. An analysis of the atmospheric moisture budget from one of the climate models shows that thermodynamic processes contribute most significantly to precipitation changes over the Great Basin, while dynamic processes are most significant for the other lakes. Lake Cari-Laufquen shows a lake expansion that is most likely attributed to reduced evaporation rather than changes in regional precipitation, suggesting that lake levels alone may not be the best indicator of how much precipitation this region receives. Our results indicate that the causes of hydrologic fluctuations are spatially diverse and that future projections will need to consider more than just thermodynamic changes for accurate regional predictions.

A relatively warm Medieval period ( nearly equal 1100-1500) and cool Little Ice Age ( nearly equal 1500-1900, coolest during the early 19th century) are reconstructed using a generalized linear model employing Bayesian inference. Plausible modern circulation analogs are considered, showing pressure composites that may have been more prevalent during the earlier compared to the later period. These analog patterns are consistent with independent reconstructions of positive NAO/AMO-like conditions during Medieval times, both of which are similar to circulation patterns simulated by GCMs using generalized sea surface temperatures consistent with La Nina-like conditions in the tropical Indo-Pacific region. The climatic patterns that generally lead to warmer summers in the study region are additionally associated with anomalous high-pressure ridging and large-scale drought, which is also consistent with drought reconstructions for North America during Medieval times. New tree ring-based reconstructions of the surface temperature field over the past 500 years in western North America and the adjacent Pacific Ocean are also presented. A key feature of these reconstructions occurs in the early 19th century, which is the coldest period across the region during this time, similar to the center-continent pollen-based record. The spatially-explicit field reconstructions are used to drive analysis of regional responses to volcanic forcing, providing a basis for examining agreement between the reconstructed response patterns and the corresponding responses in GCM simulations. The ultimate goal of comparison is to identify regionally best-performing GCM output to use as forcing input in regional impacts models. Initial application of the regional post-volcanic fingerprint to parallel analyses done with members of the NCAR CCSM suite of models suggests that significant improvement in regional fidelity has resulted from continued model development. Additional examination using a new millennium-length CCSM integration and adding European post-volcanic field reconstructions yields a more mixed picture. Finally, a rigorous experimental evaluation of the efficacy of climate field reconstruction (CFR) methods is presented, derived from the western North American temperature reconstructions. This evaluation compares the fidelity of CFRs based on real proxy predictors to those obtained by using non-informative predictors. The non-informative proxies are designed to have the same autocorrelation structure as the real proxy data, but contain no climatic information. Large ensembles of reconstructions are generated in both cases, providing estimated Monte Carlo distributions of reconstruction skill. The skill metric distributions of the real proxy-based CFRs indicate good reconstruction quality and clearly (and almost entirely) separate from the poor skill distributions generated using the non-informative proxies, in contrast to a recent similar study that suggests proxy-based reconstructions have little efficacy, but which did not evaluate CFR methods.

Globally continuous measurements of sediment fluxes are scarce and numerical models are often limited, providing small or point scale predictions only. WBMsed is a spatially and temporally explicit global riverine model predicting suspended and bedload sediment fluxes based on the WBMplus water balance and transport model (part of the FrAMES biogeochemical modeling framework). The model incorporates climate input forcings to calculate surface and subsurface runoff for each grid cell. The prediction of fluvial sediment fluxes is highly dependent on how well its transport medium, riverine water, is simulated. Analyses indicate that average water discharges are well predicted by the WBMplus model. However, daily freshwater predictions are often over or under predicted by up to an order of magnitude, significantly affecting the accuracy of sediment flux simulation capabilities of WBMsed. Therefore, WBMsed v.2.0 incorporates a floodplain reservoir component that improves high temporal resolution water discharge simulations. Here we will present the model, discuss its prediction capabilities and limitations and highlight potential applications for the broader earth-sciences community including coupling with other models.

The ACC began to develop in the middle Eocene through a shallow Drake Passage, with deepwater flow likely established by 29 Ma (Livermore et al. 2004). Rapid deepening of the Tasman gateway occurred in the late Eocene to early Oligocene). The timing of the earliest impact of the (proto-) ACC on global circulation and climate has been debated for decades. Here, we present new middle to late Eocene ( nearly equal 36-40 Ma) benthic foraminiferal stable isotopic (delta 18O, delta 13C) records and %CaCO3 data from ODP Site 1090 that extend published late Eocene-early Oligocene records (Pusz et al. 2011). Comparisons with published isotopic records (Cramer et al. 2009) highlight the development of a significant carbon isotopic (delta 13C) offset between Site 1090 (values nearly equal 0.7ppm lower) and other sites from nearly equal 37.5 to 34 Ma, reminiscent of similar low delta 13C values in this region during the Plio-Pleistocene (Hodell & Venz-Curtis, 2006). The low delta 13C interval coincides with elevated opaline silica deposition at Site 1090 (Diekmann et al. 2004), and with the development of small, but significant, meridional delta 18O gradients within the deep Atlantic basin. We interpret these observations as indicative of enhanced primary production at the northern edge of the polar front accompanied by increased thermal differentiation of northern- and sourthern-sourced deepwaters. These records are consistent with model predictions for the effects of proto-ACC development in the late Eocene (Heinze and Crowley, 1997; Toggweiler and Bjornsson, 2000).

Using frozen network experiments and pseudoproxy validation, the reconstruction is found skillful back to 1150 C.E., with inevitable amplitude reduction before 1500 C.E. due to the paucity of proxy predictors. Despite this caveat, wavelet coherency analysis reveals a marked anticorrelation between solar forcing (as estimated from cosmogenic isotope concentrations; Bard et al., 2007; Steinhilber et al., 2009) and the reconstructed NINO3.4 in the nearly equal sim205-year spectral range (DeVries cycle). The phase angle between both signals is $156 per mil 33 (super ) in this range, indicating that periods of high solar irradiance coincide with cool conditions in the NINO3.4 region, with time lag of $14 per mil 19 years. We find this result robust to the reconstruction method, estimate of solar forcing, or analysis method used to estimate the phasing. We then discuss the implication of this result for the response of tropical Pacific climate to radiative forcing. While the anti-phasing seems to favor the 'ocean dynamical thermostat' hypothesis of Clement et al [1996], this feedback appears subdued in most IPCC-class coupled general circulation models (CGCMs), where it is almost completely compensated by changes in the Pacific trade winds, linked to changes in the vertical structures of atmospheric moisture and temperature (Knutson & Manabe 1995; Held & Soden 2006; Vecchi et al. 2006). If the reconstruction is correct that past NINO3.4 SSTs have varied out of phase with solar irradiance on bicentennial scales, this would pose a new challenge both for CGCM simulations and for our understanding of the equatorial Pacific response to radiative forcing References: Clement, A.

A proto-ACC began to develop in the late middle Eocene ( nearly equal 40Ma) with shallow flow through the Drake Passage. Rapid deepening of the Tasman gateway (late Eocene to early Oligocene), and more gradual deepening of the Drake Passage through the Oligocene allowed the ACC to deepen and strengthen. The impact of the ACC on ocean circulation at its early stages of development has been debated for decades. New benthic foraminiferal delta 18O and delta 13C records from Atlantic DSDP/ODP Sites 366, 1053, and 1090, with comparisons to ASP-5 (Katz et al. 2011) and isotope compilations (Cramer et al. 2009), show that increased thermal differentiation of northern- and sourthern-sourced deepwaters began following the Middle Eocene Climate Optimum (MECO) and increased through the late Eocene. Published assemblage data from multiple microfossil groups show that major biotic changes in the surface and deep ocean began at this time. In the late Eocene, delta 13C records and published opaline silica data indicate enhanced primary productivity at the northern edge of the polar front, consistent with model predictions for the effects of proto-ACC development in the late Eocene. In the early Oligocene, a large delta 13C offset developed between mid-depth ( nearly equal 600m) and deep (>1000m) western North Atlantic waters, indicating development of intermediate-depth delta 13C and O2 minima linked in the modern ocean to northward incursion of Antarctic Intermediate Water. At the same time, the ocean's coldest waters became increasingly restricted to south of the ACC, likely forming a bottom-ocean layer, as in the modern ocean. This indicates that the modern four-layer ocean structure (surface, intermediate, deep, bottom) developed by the early Oligocene as a consequence of the ACC. We conclude that the (proto-)ACC impacted global ocean circulation by the beginning of the late Eocene, with increasing influence through the Oligocene. The timing of the oceanographic changes implies that the development of the ACC likely influenced the climate transition to continent-scale Antarctic glaciation.

The tropical atmospheric overturning circulation strengthens in all models in a manner that is dictated by the response of the hydrological cycle to tropical cooling. This response arises from the same mechanism that has been found to explain the weakening of the tropical circulation in response to anthropogenic global warming, but with opposite sign. Analysis of the model differences shows that the ascending branch of the Walker circulation strengthens via this mechanism, but vertical motion also weakens over areas of the Maritime Continent exposed due to lower sea level. Each model exhibits a different balance between these two mechanisms, and the result is a Pacific Walker circulation response that is not robust. Further, even those models that simulate a stronger Walker circulation during the LGM do not simulate clear patterns of surface cooling, such as La Nina-like cooling or enhanced equatorial cooling, as proposed by previous studies. In contrast, the changes in the Walker circulation have a robust and distinctive signature on the tilt of the equatorial thermocline, as expected from zonal momentum balance. The changes in the Walker circulation also have a clear signature on the spatial pattern of the precipitation changes. A reduction of the east-west salinity contrast in the Indian Ocean is related to the precipitation changes resulting from a weakening of the Indian Walker circulation. These results indicate that proxies of thermocline depth and sea surface salinity can be used to detect actual LGM changes in the Pacific and Indian Walker circulations, respectively and help constrain the sensitivity of the Walker circulation to tropical cooling.

The Juneau Icefield (4261 km (super 2) ) lost about 340 km (super 2) of glacier surface area between 1948 and 2009. We investigate the effect of future climate change on glacier melt and runoff of four basins in the Juneau Icefield. Glacierized areas within these basins range from 6 to 122 km (super 2) , and together comprise 5% of the total Juneau Icefield surface area. Meteorological and discharge data for all four outlet streams are available since 1965, with some records extending back to 1951. A temperature-index model including potential direct solar radiation is calibrated for each glacier based on recent mass balance and discharge data. Discharge is modeled using a linear-reservoir approach. Future scenarios RCP6.0 CCSM4 simulations are downscaled to 5-10 km resolution over the study area with the Weather Research and Forecasting (WRF) model. Results are analyzed with respect to changes in glacier runoff seasonality, peak flow and annual runoff.

Knowing which segments of the population are predisposed to mail back a form is essential to develop methods to maximize census participation and to plan for and monitor areas of nonresponse. In this article, we describe a geographic segmentation of survey and census response focused on the underlying constructs behind census tracts with historically low mail response rates. We perform a cluster analysis based on twelve demographic, housing, and socioeconomic variables used to calculate a "hard-to-count" score. This yielded eight mutually exclusive geographic clusters of the population that varied across the spectrum of mailback propensities. Each segment is distinguished by unique demographic, housing, and socioeconomic characteristics and several segments are closely aligned to three different hard-to-count profiles. To gauge how the segments performed in terms of recent mail response behavior, we examine several outcome measures with data from the 2010 Census and the American Community Survey collected in 2009 and 2010. To conclude, we discuss the usefulness of extending this geographic segmentation model beyond the census to targeted experiments and other applications in demographic surveys.

Notwithstanding the difficulty in modeling frozen soil moisture interactions in discontinuous permafrost basins and simulating the inputs of moisture into the soil profile via snow melt; hydro-climatologic data sets in the high latitudes are often short, discontinuous, and require rigorous validation to ensure data quality prior to their use in forcing models. This work presents results from the first phase of a broader modeling project in the Chena River basin, a 6500 km (super 2) watershed located in interior Alaska near the town of Fairbanks. This basin has been the stage of several costly and damaging flood events that led to development of flood control structures by the US Army Corps of Engineers. The focus of the initial examination is on the relationships between basin aspect, permafrost, vegetation and climate (temperature, precipitation and snow pack) observed in historical records and satellite imagery. The goal of the work is to improve permafrost processing and snow cover observations within the River Forecast Center's hydrologic modeling framework (CHPS; SAC-SMA and SNOW17). The improved models will eventually be used to investigate changes in historical and future patterns of extreme hydro-climate events. North and south facing aspects are a distinct control on snow melt in this watershed, which is related to the regional hydro-climate via physiographic and vegetation controls. Identifying these relationships in the historical record provides important context for modeling future changes as projected by regional climate models, as future temperature and precipitation regimes and possible threshold responses in permafrost could shift these relationships and result in changes in extremes. These findings and the exploration intended for the broader project are anticipated to be valuable for both engineers and forecasters who are interested in extreme hydro-climate impacts in this region of the north.

Reconstructions are collaborative, built on the research of hundreds of scientists who apply their diverse scientific expertise and field and laboratory skill to create the individual proxy reconstructions that underlie the multi-proxy, global average temperature time series. Web 2.0 features have enabled collaborative efforts that improve the characterization of uncertainty. Raw data shared via a repository (the World Data Center for Paleoclimatology) enable new reconstructions from the collection of user-generated data. Standards propagated by expert communities facilitate quality control and interoperability. Open access to data and computer code promote transparency and make the science accessible to a broader audience. Blogs, wikis, and listservs share background information and highlight contentious as well as unique aspects of paleo science. A novel approach now underway, titled the Paleoclimate Reconstruction Challenge, and based on the sharing of simulated data (pseudo-proxies) and reconstruction results, seeks to facilitate method development, further reducing uncertainty. Broadly-useful aspects of the Challenge may find application in other fields.

The measurements were modelled using a constrained box-model based upon the Master Chemical Mechanism (MCM). The agreement between modelled and measured HO sub(2)+RO sub(2) was typically within 40% and, in the unpolluted regions, within 30%. The analysis of the model results suggests that the MCM might underestimate the concentrations of some acyl peroxy radicals and other small peroxy radicals. The model underestimated the measurements of NO sub(3) by 60-70%, possibly because of rapid heterogeneous uptake of N sub(2)O sub(5). The MCM model results were used to estimate the composition of the peroxy radical pool and to quantify the role of DMS, isoprene and alkenes in the formation of RO sub(2) in the different regions. The measurements of HO sub(2)+RO sub(2) and NO sub(3) were also used to calculate the gas-phase budget of NO sub(3) and quantify the importance of organic peroxy radicals as NO sub(3) sinks. RO sub(2) accounted, on average, for 12-28% of the total gas-phase NO sub(3) losses in the unpolluted regions and for 1-2% of the total gas-phase NO sub(3) losses in the polluted regions.

Aerosols have important consequences for global climate, ecosystem processes and human health due to their various sizes and chemical compositions. In this paper, nearly 23 years of aerosol optical thickness (AOT) data from operational satellite AVHRR observations over the global ocean have been used to study the latitudinal variations of the linear long-term trends (LLT) of zonal mean AOT. For the LLT of zonally averaged AOT over the global ocean, their significance generally falls below the 95% confidence level. However, the LLT of zonal mean AOT for the individual oceans, such as the Atlantic Ocean (AO), Indian Ocean (IO), and West Pacific Ocean (WPO), can easily pass 95% confidence level in some latitude belts (e.g. 5-25?N for IO, 33-40?N for WPO, 30-50?N for AO) and may produce zonally averaged solar dimming/brightening accordingly in cloudless conditions. The results will help us to understand the latitudinal features of the decadal changes in aerosol loadings, as well as surface solar radiation, better. Published in 2011 by John Wiley & Sons, Ltd.

Geologic mapping of the 1998 lava flows has been carried out with a combination of visual observations from multiple submersible dives since 1998, and with high-resolution bathymetry, most recently collected with the MBARI mapping AUV (the D. Allan B.) since 2007. The new mapping results revise and update the previous preliminary flow outlines, areas, and volumes. The high-resolution bathymetry (1-m grid cell size) allows eruptive fissures fine-scale morphologic features to be resolved with new and remarkable clarity. The morphology of both lava flows can be interpreted as a consequence of a specific sequence of events during their emplacement. The northern sheet flow is long (4.6 km) and narrow (500 m), and erupted in the SE part of Axial caldera, where it temporarily ponded and inflated on relatively flat terrain before draining out southward toward steeper slopes. The inflation and drain-out of this sheet flow by approximately 3.5 m over 2.5 hours was previously documented by a monitoring instrument that was caught in the lava flow. Our geologic mapping shows that the morphology of the northern sheet flow varies along its length primarily due to gradients in the underlying slope and processes active during flow emplacement. The original morphology of the sheet flow where it ponded is lobate, with pillows near the margins, whereas the central axis of drain-out and collapse is floored with lineated, ropy, and jumbled lava morphologies. The southern lava flow, in contrast, is mostly pillow lava where it cascaded down the steep slope on the east flank of the south rift zone, but also has a major area of collapse where lava ponded temporarily near the rift axis. These results show that submarine lava flows have more subsurface hydraulic connectivity than has previously been supposed. For example, a common morphologic feature at the downslope ends of the 1998 lava flows (and on many older flows at Axial) is large lobes covered with pillows that are 200-500-m in diameter, 10-20-m thick, and are capped with centered, dendritic collapse areas 5-10 m deep. These large lobes show clear evidence of inflation and drain-out, and are often arranged in a shingle-like fashion, implying progressive emplacement at decreasing distance from the eruptive vent with time. Such features are impossible to discern from visual observations alone and are only revealed by high-resolution bathymetry.

This activity reflects widening of the S. Mariana Trough. Stretching formed 3 southeast-facing, broad rifts extending from the trench to an extinct arc volcano chain ( approximately 80km from the trench axis) that is mostly composed of outcrops and fragments of pillow lavas partially covered by sediments. The 3 rifts comprise the S.E. Mariana Forearc Rift (SEMFR) and are 50-56km long and 3600 to 8200m deep, with axial valleys that narrow near the extinct arc. We studied the SEMFR using one Shinkai 6500 dive in 2008 and two Shinkai 6500 dives and 7 deep-tows in 2010. Near the trench, the SEMFR flanks are very steep and dominated by talus slopes of lava, fine-grained gabbro, diabase and peridotite, sometimes covered by thin volcaniclastic sediments. Few outcrops of pillow lavas, lava flows and volcaniclastics are observed, strongly suggesting that SEMFR morphology is dominated by faulting and landsliding. Lava outcrops are smoother and better preserved towards the extinct arc, suggesting that magmatic activity dominates that part of the rift. (super 40) Ar- (super 39) Ar ages of 3 SEMFR lavas are 3.0-3.7 Ma, so post-magmatic rifting is younger than approximately 3Ma. SEMFR pillow lavas are vesicular and microporphyritic with crystallite-rich glassy rinds, indicating they erupted underwater at near-liquidus conditions. In contrast, the lava flows are more crystallized and less vesicular. SEMFR lavas exhibit similar ranges in mineral composition with 2 kinds of plagioclase (An>80% and An or =80% and Mg#90 and Fo<90), suggesting magma mixing. Gabbroic rocks are slightly altered and have olivine and clinopyroxene compositions similar to those of the lavas, but contain less anorthitic plagioclase with a wider range in composition (An20-70) than the lavas. One sample of the extinct arc lava is vesicular and aphyric, consistent with near-liquidus eruption conditions. SEMFR lavas are low-K calk-alkaline basalts to andesites, whereas lava from the extinct arc is tholeiitic basaltic andesite similar to those erupted from the Malaguana-Gadao Ridge. These lavas are enriched in LILE and depleted in HFSE, consistent with subduction zone settings. Their similar Yb-normalized trace element patterns (Pearce et al., 2005), with different enrichment in LILE, suggest that SEMFR lavas were produced from a relatively homogenous mantle source that interacted with different proportions of subduction-derived components. Only SEMFR lavas sampled near the extinct arc exhibit different petrographic and geochemical features (higher abundances in olivine and clinopyroxene, lower HREE patterns, lower Nb/Yb and higher Ba/Th), indicating that a more depleted mantle source interacted with a greater subduction input.

The site was chosen for detailed study after a water column survey using a towed CTD package identified intense particle plumes rising up to 250m above seafloor along the entire segment (see abstracts by Baker et al. and Holden et al., this meeting). The segment is characterized by ridge-and-valley terrain with the most recent neovolcanic ridge extending, respectively, 25 km west and 20 km east of a central low-relief area that is quasi-circular, approximately 2 km radius, less than 30 m high. The neovolcanic ridge, revealed by the EM302 bathymetry to be a generally hummocky edifice less than 1 km wide and under approximately 40 m high, is cut by a very small axial graben barely resolved in the EM302 bathymetry. Two areas were surveyed during five ROV dives, four on the central area near 88 deg 18.5'W and one dive at 14 km east at 88 deg 10.8'W. A third high intensity plume target near the western extremity of the segment at 88 deg 27.2'W was not investigated using the ROV. The recent lobate and pillow lava flows were emplaced in narrow grabens along and adjacent to the neovolcanic ridge. In several places, the flow was observed to fill the axial graben. It is likely that the flow thickness ranges from meters to 10's of meters, depending upon the pre-eruption graben size and local effusion variations. However, no long, channel-fed lava flows were found. Flow boundaries based on preliminary ROV navigation average less than 100 meters across-axis. The lobate lavas all had a very similar glassy appearance and negligible sediment cover, making them easy to recognize amid the surrounding, older flows. The age of these lavas appeared visually younger than the youngest lavas observed near Rosebud vent field, which were erupted between 1990 and 2002. Diffuse venting characterized by high microbial productivity and mobile vent fauna on the young lavas were found at both sites and indicate a youthful hydrothermal system associated with a diking event similar to those characterized on the East Pacific Rise and Juan de Fuca Ridge during the past two decades (also see abstract by Shank et al., this meeting). Thus, the known extent of this eruption is at least 14 km along axis. If the third site to the west is also shown to be characterized by young lavas the diking event would be approximately 30 km in total length making it the longest submarine diking event documented to date and showing that single diking events can relieve stress over entire an segment on the GSC. This latest serendipitous discovery of a probable major seafloor spreading event emphasizes the need for a better monitoring system along eastern Pacific spreading centers to "catch" these events in real-time and provide context for follow-up in situ studies.

Such operations, relying upon real-time video, data and telemetry-links between the surface support ship and the ROV at the seabed, provide a subset of the opportunities available from HOV-based science to a much wider pool of scientific expertise, in real-time, than any (practically) imaginable deep-diving HOV could support. Now, the vision of the NOAA Ocean Exploration program presents the opportunity to take a further step by transmitting live, via satellite, from the ocean floor to shore-based expedition command centers (ECC) that interested scientists can populate without even having to go to sea. In this cruise we will report on the latest results from an Ocean Exploration cruise to the Mid-Cayman Rise (MCR) conducted in August 2010 using a combination of multibeam mapping, CTD-rosette hydrocasts equipped with in situ sensors, shipboard dissolved methane analyses and detailed seafloor investigation using the Little Herc ROV. Our prime objective is to explore off-axis away from the previously-investigated rift-valley floor and focus, instead, on the oceanic core complexes that appear to dominate construction of the rift valley walls along much of the MCR. As well as our geologic exploration we also plan to investigate the benthic biology of the areas we visit including, importantly, any novel hydrothermal systems that the shallow off-axis portions of the MCR may host.

The affected species include: 73 species in the snapper grouper complex, dolphin, wahoo, golden crab, and two species of Sargassum, a free-floating seaweed that provides essential habitat to numerous fish species and protected resources. The amendment would establish ACLs to prevent overfishing and AMs such as specification of an annual catch target (ACT), in-season regulations changes, post-season regulation changes, and specification of other management measures (e.g., bag limits). This final EIS analyzes 31 actions, including: changes to the species managed by the snapper-grouper FMP; specification of an acceptable biological catch (ABC) for species in FMPs for snapper-grouper, dolphin-wahoo, golden crab, and Sargassum; ACTs to account for management uncertainty, such as compliance rates; jurisdictional allocations between the South Atlantic and the Gulf of Mexico for black grouper, mutton snapper and yellowtail snapper, and sector allocations (between commercial and recreational sectors) for dolphin-wahoo and snapper-grouper species; and management measures for wreckfish, dolphin, and wahoo. The preferred alternatives include: removal of 13 species from the snapper-grouper FMP; development of species groups for remaining species in the snapper-grouper FMP based on life history, catch statistics, and fishery-independent data; establishment of ABCs for dolphin and wahoo at 14.6 million pounds and 1.5 million pounds, respectively; and establishment of an ABC for golden crab at two million pounds. An ACL is in place for Sargassum in the form of a 5,000-pound commercial quota and it is likely that there are no vessels harvesting Sargassum. Additional management measures would set a recreational bag limit of one wreckfish per vessel per day; set the closed season for the recreational sector from January 1 through June 30, and September 1 through December 31 each year; prohibit recreational bag limit sales of dolphin from for hire vessels; and establish a minimum size limit for dolphin of 20 inches for South Carolina. POSITIVE IMPACTS: Implementation would ensure mortality is at or below the annual limits and targets for the respective species. Reducing the number of species in the snapper grouper FMP would reduce the administrative impacts of establishing, monitoring, and implementing limits and targets. NEGATIVE IMPACTS: ACLs may lead to short-run reductions in gross revenue for the commercial sector, but may also generate higher long-run gross revenue as annual allowable harvest levels are raised due to recovery of overfished stocks. Once the ACL is specified, the administrative burden associated with monitoring, enforcement, and implementing management measures would increase. Future AMs are expected to generate adverse indirect economic effects on fishery participants. LEGAL MANDATES: Magnuson Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

Hydrocarbons are detected using flame ionization detection, and inert species can be detected by thermal conductivity. The present apparatus has been utilized to measure diffusion coefficients at substantially higher temperatures than previous RF-GC work. Characterization of the new apparatus was accomplished by comparing measured binary diffusion coefficients of dilute argon in helium to established reference values. Further diffusion coefficient measurements for dilute helium in argon and dilute nitrogen in helium (using thermal conductivity detection) and dilute methane in helium (using flame ionization detection) were performed and found to be in excellent agreement with literature values. The measurement of these well-established diffusion coefficients has shown that specific experimental conditions are required for accurate diffusion measurements using this technique, particularly at higher temperatures. Numerical simulations of the diffusion experiments are presented to demonstrate that artifacts of the analysis procedure must be specifically identified to ensure accuracy, particularly at higher temperatures.

[Part 11 of 11] T2 - OUTER CONTINENTAL SHELF OIL AND GAS LEASING PROGRAM: 2012-2017, WESTERN, CENTRAL AND EASTERN GULF OF MEXICO AND BEAUFORT SEA, CHUKCHI SEA, AND COOK INLET, ALASKA. AN - 917565476; 15139-2_0011 AB - PURPOSE: Fifteen oil and gas lease sales in six Outer Continental Shelf (OCS) planning areas in the Gulf of Mexico (GOM) and offshore Alaska during the period 2012-2017 are proposed. Five area-wide lease sales each would be held in the Central and Western GOM Planning Areas, with one to two lease sales in the extreme western portion of the Eastern GOM Planning Area. Scheduled in the Alaska Region would be one sale with two whaling deferrals in the Beaufort Sea Planning Area, one sale with a 25-mile buffer in the Chukchi Sea Planning Area, and one special interest sale in the Cook Inlet Planning Area. An updated oil and gas strategy for the OCS continued a moratorium for areas in the Eastern GOM and eliminated the Mid-Atlantic and South Atlantic planning areas from consideration for potential sales and development through the 2017 planning horizon. Oil and gas activities may occur on OCS leases after a lease sale pursuant to the proposed action, and these activities may extend over a period of 40 to 50 years. These activities may include seismic surveys; drilling oil and natural gas exploration and production wells; installation and operation of offshore platforms and pipelines, onshore pipelines, and support facilities; and transporting oil using ships or pipelines. Eight alternatives, including a No Action Alternative (Alternative 8) are considered in this programmatic draft EIS. Under the proposed action (Alternative 1), a schedule would be established and used as a basis for considering where and when leasing might be appropriate in the six planning areas over the five-year period. Alternatives 2 through 7 each exclude one of the six planning areas included in the proposed action from the program. In addition to evaluating the impacts of routine operations and accidental oil spills, this programmatic draft EIS also considers how climate change may affect baseline conditions of resources over the 40 to 50 year period during which oil and gas production could occur following lease sales under the program. POSITIVE IMPACTS: A schedule of lease sales would best meet national energy needs for the five-year period following its approval by balancing the potential for adverse environmental and societal impacts with the beneficial impacts of the discovery and development of oil and gas. NEGATIVE IMPACTS: Disturbance of the seafloor would result in moderate impacts to benthic habitats and invertebrates. Routine operations could result in minor to moderate, localized, short-term impacts to water quality, air quality, and the acoustic environment. Coastal and estuarine habitats could incur minor to moderate impacts from pipeline landfall and construction, maintenance dredging of inlets and channels, and vessel traffic. Potential impacts to marine mammals include noise disturbance from seismic surveys, vessels, helicopters, construction and operation of platforms, and removal of platforms with explosives; potential collision with vessels; and exposures to discharges and wastes. Five species of sea turtles that occur in the three GOM planning areas could be impacted. Accidental oil spills could affect benthic, pelagic, coastal, and estuarine habitat and pose the greatest threat to marine and coastal birds. American crocodile could be affected in the event there is a very large oil spill that reaches the southern Florida coast. Operations could have minor impacts on subsistence, commercial, and recreational fisheries.

[Part 4 of 11] T2 - OUTER CONTINENTAL SHELF OIL AND GAS LEASING PROGRAM: 2012-2017, WESTERN, CENTRAL AND EASTERN GULF OF MEXICO AND BEAUFORT SEA, CHUKCHI SEA, AND COOK INLET, ALASKA. AN - 917565198; 15139-2_0004 AB - PURPOSE: Fifteen oil and gas lease sales in six Outer Continental Shelf (OCS) planning areas in the Gulf of Mexico (GOM) and offshore Alaska during the period 2012-2017 are proposed. Five area-wide lease sales each would be held in the Central and Western GOM Planning Areas, with one to two lease sales in the extreme western portion of the Eastern GOM Planning Area. Scheduled in the Alaska Region would be one sale with two whaling deferrals in the Beaufort Sea Planning Area, one sale with a 25-mile buffer in the Chukchi Sea Planning Area, and one special interest sale in the Cook Inlet Planning Area. An updated oil and gas strategy for the OCS continued a moratorium for areas in the Eastern GOM and eliminated the Mid-Atlantic and South Atlantic planning areas from consideration for potential sales and development through the 2017 planning horizon. Oil and gas activities may occur on OCS leases after a lease sale pursuant to the proposed action, and these activities may extend over a period of 40 to 50 years. These activities may include seismic surveys; drilling oil and natural gas exploration and production wells; installation and operation of offshore platforms and pipelines, onshore pipelines, and support facilities; and transporting oil using ships or pipelines. Eight alternatives, including a No Action Alternative (Alternative 8) are considered in this programmatic draft EIS. Under the proposed action (Alternative 1), a schedule would be established and used as a basis for considering where and when leasing might be appropriate in the six planning areas over the five-year period. Alternatives 2 through 7 each exclude one of the six planning areas included in the proposed action from the program. In addition to evaluating the impacts of routine operations and accidental oil spills, this programmatic draft EIS also considers how climate change may affect baseline conditions of resources over the 40 to 50 year period during which oil and gas production could occur following lease sales under the program. POSITIVE IMPACTS: A schedule of lease sales would best meet national energy needs for the five-year period following its approval by balancing the potential for adverse environmental and societal impacts with the beneficial impacts of the discovery and development of oil and gas. NEGATIVE IMPACTS: Disturbance of the seafloor would result in moderate impacts to benthic habitats and invertebrates. Routine operations could result in minor to moderate, localized, short-term impacts to water quality, air quality, and the acoustic environment. Coastal and estuarine habitats could incur minor to moderate impacts from pipeline landfall and construction, maintenance dredging of inlets and channels, and vessel traffic. Potential impacts to marine mammals include noise disturbance from seismic surveys, vessels, helicopters, construction and operation of platforms, and removal of platforms with explosives; potential collision with vessels; and exposures to discharges and wastes. Five species of sea turtles that occur in the three GOM planning areas could be impacted. Accidental oil spills could affect benthic, pelagic, coastal, and estuarine habitat and pose the greatest threat to marine and coastal birds. American crocodile could be affected in the event there is a very large oil spill that reaches the southern Florida coast. Operations could have minor impacts on subsistence, commercial, and recreational fisheries. Any adverse impacts on fish and mammal subsistence resources could have disproportionate impacts on Alaska Native populations.

[Part 1 of 1] T2 - REEF FISH AMENDMENT 32: GAG REBUILDING PLAN, ANNUAL CATCH LIMITS, MANAGEMENT MEASURES; RED GROUPER ANNUAL CATCH LIMITS, MANAGEMENT MEASURES; GROUPER ACCOUNTABILITY MEASURES, GULF OF MEXICO. AN - 917565150; 15134-7_0001 AB - PURPOSE: Amendment 32 to the Reef Fish Fishery Management Plan to set new annual catch limits (ACLs) and accountability measures (AMs) for managing gag grouper, red grouper, and shallow-water grouper stocks in the Gulf of Mexico is proposed. Gag and red grouper are the two most abundant grouper species in the Gulf of Mexico and account for the bulk of the recreational and commercial grouper landings. Currently, commercial harvest of grouper is managed under an individual fishing quota (IFQ) system. Management of the recreational sector has used traditional measures such as minimum size limits, aggregate and species-specific bag limits, and a closed season. Both sectors are subject to area closures. Amendment 32 establishes annual catch limits and annual catch targets for 2012 to 2015 for gag and for 2012 for red grouper. Additional actions include: rebuilding plans for the gag stock; establishing or modifying recreational bag limits, size limits, and closed seasons for gag and red grouper in 2012; applying commercial gag and shallow-water grouper quota adjustments to account for dead discards; adjusting multi-use shares (allocation) in the grouper IFQ program; reducing the commercial gag size limit; establishing time and area closures; and modifying current gag, red grouper, and shallow-water grouper AMs. Several alternatives, including a No Action Alternative, are considered for each of the seven actions addressed in this final EIS. The preferred alternatives would: establish a plan to rebuild the gag stock to a level consistent with producing maximum sustainable yield in 10 years or less; set the recreational gag season for July 1 through October 31 with a two fish bag limit, a four fish aggregate bag limit, and a 22 inch minimum size limit; increase the red grouper bag limit to four fish per person; reduce the commercial gag quota to 86 percent of the annual catch target; reduce the commercial gag minimum size limit from 24 inches to 22 inches; use the IFQ program already in place as the AM for the commercial sector; and add an overage adjustment to be applied when gag or red grouper are considered overfished and AMs to close a season early if needed. POSITIVE IMPACTS: Implementation would decrease or end overfishing of gag and would allow the optimum yield of red grouper to continue to be caught as the stock recovers from a 2005 episodic mortality event, most likely associated with red tide. The rebuilding plan for gag and constraints on red grouper harvests would ultimately restore and maintain the stocks at a level that will allow the maximum benefits in yield and recreational fishing opportunities to be achieved. NEGATIVE IMPACTS: Short-term negative socioeconomic impacts could occur due to the need to limit directed harvest and reduce bycatch mortality. Between 2012 and 2015, the present value of losses expected to result from commercial quota reductions for gag grouper are estimated at $472,167.

[Part 10 of 11] T2 - OUTER CONTINENTAL SHELF OIL AND GAS LEASING PROGRAM: 2012-2017, WESTERN, CENTRAL AND EASTERN GULF OF MEXICO AND BEAUFORT SEA, CHUKCHI SEA, AND COOK INLET, ALASKA. AN - 917564668; 15139-2_0010 AB - PURPOSE: Fifteen oil and gas lease sales in six Outer Continental Shelf (OCS) planning areas in the Gulf of Mexico (GOM) and offshore Alaska during the period 2012-2017 are proposed. Five area-wide lease sales each would be held in the Central and Western GOM Planning Areas, with one to two lease sales in the extreme western portion of the Eastern GOM Planning Area. Scheduled in the Alaska Region would be one sale with two whaling deferrals in the Beaufort Sea Planning Area, one sale with a 25-mile buffer in the Chukchi Sea Planning Area, and one special interest sale in the Cook Inlet Planning Area. An updated oil and gas strategy for the OCS continued a moratorium for areas in the Eastern GOM and eliminated the Mid-Atlantic and South Atlantic planning areas from consideration for potential sales and development through the 2017 planning horizon. Oil and gas activities may occur on OCS leases after a lease sale pursuant to the proposed action, and these activities may extend over a period of 40 to 50 years. These activities may include seismic surveys; drilling oil and natural gas exploration and production wells; installation and operation of offshore platforms and pipelines, onshore pipelines, and support facilities; and transporting oil using ships or pipelines. Eight alternatives, including a No Action Alternative (Alternative 8) are considered in this programmatic draft EIS. Under the proposed action (Alternative 1), a schedule would be established and used as a basis for considering where and when leasing might be appropriate in the six planning areas over the five-year period. Alternatives 2 through 7 each exclude one of the six planning areas included in the proposed action from the program. In addition to evaluating the impacts of routine operations and accidental oil spills, this programmatic draft EIS also considers how climate change may affect baseline conditions of resources over the 40 to 50 year period during which oil and gas production could occur following lease sales under the program. POSITIVE IMPACTS: A schedule of lease sales would best meet national energy needs for the five-year period following its approval by balancing the potential for adverse environmental and societal impacts with the beneficial impacts of the discovery and development of oil and gas. NEGATIVE IMPACTS: Disturbance of the seafloor would result in moderate impacts to benthic habitats and invertebrates. Routine operations could result in minor to moderate, localized, short-term impacts to water quality, air quality, and the acoustic environment. Coastal and estuarine habitats could incur minor to moderate impacts from pipeline landfall and construction, maintenance dredging of inlets and channels, and vessel traffic. Potential impacts to marine mammals include noise disturbance from seismic surveys, vessels, helicopters, construction and operation of platforms, and removal of platforms with explosives; potential collision with vessels; and exposures to discharges and wastes. Five species of sea turtles that occur in the three GOM planning areas could be impacted. Accidental oil spills could affect benthic, pelagic, coastal, and estuarine habitat and pose the greatest threat to marine and coastal birds. American crocodile could be affected in the event there is a very large oil spill that reaches the southern Florida coast. Operations could have minor impacts on subsistence, commercial, and recreational fisheries. Any adverse impacts on fish and mammal subsistence resources could have disproportionate impacts on Alaska Native populations.

[Part 5 of 11] T2 - OUTER CONTINENTAL SHELF OIL AND GAS LEASING PROGRAM: 2012-2017, WESTERN, CENTRAL AND EASTERN GULF OF MEXICO AND BEAUFORT SEA, CHUKCHI SEA, AND COOK INLET, ALASKA. AN - 917564663; 15139-2_0005 AB - PURPOSE: Fifteen oil and gas lease sales in six Outer Continental Shelf (OCS) planning areas in the Gulf of Mexico (GOM) and offshore Alaska during the period 2012-2017 are proposed. Five area-wide lease sales each would be held in the Central and Western GOM Planning Areas, with one to two lease sales in the extreme western portion of the Eastern GOM Planning Area. Scheduled in the Alaska Region would be one sale with two whaling deferrals in the Beaufort Sea Planning Area, one sale with a 25-mile buffer in the Chukchi Sea Planning Area, and one special interest sale in the Cook Inlet Planning Area. An updated oil and gas strategy for the OCS continued a moratorium for areas in the Eastern GOM and eliminated the Mid-Atlantic and South Atlantic planning areas from consideration for potential sales and development through the 2017 planning horizon. Oil and gas activities may occur on OCS leases after a lease sale pursuant to the proposed action, and these activities may extend over a period of 40 to 50 years. These activities may include seismic surveys; drilling oil and natural gas exploration and production wells; installation and operation of offshore platforms and pipelines, onshore pipelines, and support facilities; and transporting oil using ships or pipelines. Eight alternatives, including a No Action Alternative (Alternative 8) are considered in this programmatic draft EIS. Under the proposed action (Alternative 1), a schedule would be established and used as a basis for considering where and when leasing might be appropriate in the six planning areas over the five-year period. Alternatives 2 through 7 each exclude one of the six planning areas included in the proposed action from the program. In addition to evaluating the impacts of routine operations and accidental oil spills, this programmatic draft EIS also considers how climate change may affect baseline conditions of resources over the 40 to 50 year period during which oil and gas production could occur following lease sales under the program. POSITIVE IMPACTS: A schedule of lease sales would best meet national energy needs for the five-year period following its approval by balancing the potential for adverse environmental and societal impacts with the beneficial impacts of the discovery and development of oil and gas. NEGATIVE IMPACTS: Disturbance of the seafloor would result in moderate impacts to benthic habitats and invertebrates. Routine operations could result in minor to moderate, localized, short-term impacts to water quality, air quality, and the acoustic environment. Coastal and estuarine habitats could incur minor to moderate impacts from pipeline landfall and construction, maintenance dredging of inlets and channels, and vessel traffic. Potential impacts to marine mammals include noise disturbance from seismic surveys, vessels, helicopters, construction and operation of platforms, and removal of platforms with explosives; potential collision with vessels; and exposures to discharges and wastes. Five species of sea turtles that occur in the three GOM planning areas could be impacted. Accidental oil spills could affect benthic, pelagic, coastal, and estuarine habitat and pose the greatest threat to marine and coastal birds. American crocodile could be affected in the event there is a very large oil spill that reaches the southern Florida coast. Operations could have minor impacts on subsistence, commercial, and recreational fisheries. Any adverse impacts on fish and mammal subsistence resources could have disproportionate impacts on Alaska Native populations.

Preparation date: November 11, 2011 N1 - Last updated - 2012-01-16 ER - TY - RPRT T1 - REEF FISH AMENDMENT 32: GAG REBUILDING PLAN, ANNUAL CATCH LIMITS, MANAGEMENT MEASURES; RED GROUPER ANNUAL CATCH LIMITS, MANAGEMENT MEASURES; GROUPER ACCOUNTABILITY MEASURES, GULF OF MEXICO. AN - 916143371; 15134 AB - PURPOSE: Amendment 32 to the Reef Fish Fishery Management Plan to set new annual catch limits (ACLs) and accountability measures (AMs) for managing gag grouper, red grouper, and shallow-water grouper stocks in the Gulf of Mexico is proposed. Gag and red grouper are the two most abundant grouper species in the Gulf of Mexico and account for the bulk of the recreational and commercial grouper landings. Currently, commercial harvest of grouper is managed under an individual fishing quota (IFQ) system. Management of the recreational sector has used traditional measures such as minimum size limits, aggregate and species-specific bag limits, and a closed season. Both sectors are subject to area closures. Amendment 32 establishes annual catch limits and annual catch targets for 2012 to 2015 for gag and for 2012 for red grouper. Additional actions include: rebuilding plans for the gag stock; establishing or modifying recreational bag limits, size limits, and closed seasons for gag and red grouper in 2012; applying commercial gag and shallow-water grouper quota adjustments to account for dead discards; adjusting multi-use shares (allocation) in the grouper IFQ program; reducing the commercial gag size limit; establishing time and area closures; and modifying current gag, red grouper, and shallow-water grouper AMs. Several alternatives, including a No Action Alternative, are considered for each of the seven actions addressed in this final EIS. The preferred alternatives would: establish a plan to rebuild the gag stock to a level consistent with producing maximum sustainable yield in 10 years or less; set the recreational gag season for July 1 through October 31 with a two fish bag limit, a four fish aggregate bag limit, and a 22 inch minimum size limit; increase the red grouper bag limit to four fish per person; reduce the commercial gag quota to 86 percent of the annual catch target; reduce the commercial gag minimum size limit from 24 inches to 22 inches; use the IFQ program already in place as the AM for the commercial sector; and add an overage adjustment to be applied when gag or red grouper are considered overfished and AMs to close a season early if needed. POSITIVE IMPACTS: Implementation would decrease or end overfishing of gag and would allow the optimum yield of red grouper to continue to be caught as the stock recovers from a 2005 episodic mortality event, most likely associated with red tide. The rebuilding plan for gag and constraints on red grouper harvests would ultimately restore and maintain the stocks at a level that will allow the maximum benefits in yield and recreational fishing opportunities to be achieved. NEGATIVE IMPACTS: Short-term negative socioeconomic impacts could occur due to the need to limit directed harvest and reduce bycatch mortality. Between 2012 and 2015, the present value of losses expected to result from commercial quota reductions for gag grouper are estimated at $472,167. Losses would affect primarily Florida Gulf Coast communities. More restrictive management measures may require increased enforcement and administrative burden.

AN - 917563304; 15127-0_0001 AB - PURPOSE: The 2011 Comprehensive Annual Catch Limit (ACL) Amendment to the Fishery Management Plans (FMPs) for the Reef Fish, Spiny Lobster, Queen Conch resources, and Corals and Reef Associated Plants and Invertebrates in the U.S. Caribbean, Puerto Rico and the U.S. Virgin Islands (USVI) is proposed. Specifically, Amendment 6 to the Reef Fish FMP, Amendment 5 to the FMP for the spiny lobster fishery, Amendment 3 to the FMP for the queen conch resources, and Amendment 3 to the FMP for corals and reef associated plants and invertebrates would bring those fisheries into compliance with the 2007 revisions to the Magnuson-Stevens Fishery Conservation and Management Act (MSA). The alternatives analyzed in this final EIS would: establish ACLs for species where the rate of removal is not too high, and put AMs into place to protect the fish stocks in both the commercial and recreational sectors; initiate the transfer of all aquarium trade species included in the Coral and Reef Associated Plants and Invertebrates and the Reef Fish FMPs into a new FMP dedicated to aquarium trade species; with the exception of queen conch, remove from federal management all species previously included in the Queen Conch Resources FMP; and establish boundaries for purposes of applying AMs in federal waters. Recreational fishing bag limits would be established as follows: for the reef fish species mentioned above, a bag limit of five fish per person per day, with no more than one surgeonfish per person per day within the aggregate; a vessel limit of fifteen fish per day, including no more than four surgeonfish per vessel per day; and for spiny lobster, a bag limit of three spiny lobsters per person per day with a vessel limit of ten spiny lobsters per day. The amendment establishes separate ACLs for each of the commercial and recreational sectors in the federal waters of Puerto Rico, establishes framework provisions for the Spiny Lobster FMP, and modifies framework provisions for the Coral and Reef Associated Invertebrates FMP. Additionally, guidelines for triggering accountability measures and for applying those measures are provided. POSITIVE IMPACTS: The Comprehensive ACL Amendment would promote the sustainability of the U.S. Caribbean fisheries resources by improving targets and thresholds of reef fish, spiny lobster, conch resources, and coral and plants and associated invertebrates. NEGATIVE IMPACTS: Potential adverse impacts due to a shortened federal fishing season and lower landings would create additional stresses for relatively small commercial fishing operations and the fishing communities of Puerto Rico and the USVI. With the least amount of fishable habitat in territorial waters, it is expected that St. Thomas/St. John fishers would be least able to mitigate for lost landings. More conservative ACL values would trigger management review and action more frequently and thus is more administratively burdensome.

Rate coefficients for the OH + CH sub(3)COCHO (k sub(1)) reaction were measured under pseudo-first-order conditions in OH as a function of temperature (211-373 K) and pressure (100-220 Torr, He and N sub(2) bath gases) using pulsed laser photolysis to produce OH radicals and laser induced fluorescence to measure its temporal profile. k sub(1) was found to be independent of the bath gas pressure with k sub(1)(295 K) = (1.29 +/- 0.13) 10 super(-11) cm super(3) molecule super(-1) s super(-1) and a temperature dependence that is well represented by the Arrhenius expression k sub(1)(T) = (1.74 +/- 0.20) 10 super(-12) exp[(590 +/- 40)/T] cm super(3) molecule super(-1) s super(-1) where the uncertainties are 2 sigma and include estimated systematic errors. Rate coefficients for the NO sub(3) + (CHO) sub(2) (k sub(3)) and NO sub(3) + CH sub(3)COCHO (k sub(4)) reactions were measured using a relative rate technique to be k sub(3)(296 K) = (4.0 +/- 1.0) 10 super(-16) cm super(3) molecule super(-1) s super(-1) and k sub(4)(296 K) = (5.1 +/- 2.1) 10 super(-16) cm super(3) molecule super(-1) s super(-1). k sub(3)(T) was also measured using an absolute rate coefficient method under pseudo-first-order conditions at 296 and 353 K to be (4.2 +/- 0.8) 10 super(-16) and (7.9 +/- 3.6) 10 super(-16) cm super(3) molecule super(-1) s super(-1), respectively, in agreement with the relative rate result obtained at room temperature. The atmospheric implications of the OH and NO sub(3) reaction rate coefficients measured in this work are discussed.

The SAIPE program produces poverty estimates for the total population and median household income estimates annually for all counties and states. SAIPE data also produces single-year poverty estimates for the school-age population (age 5-17) for all school districts in the U.S. The main objective of the SAIPE program is to provide timely, reliable estimates of income and poverty statistics for the administration of federal programs and the allocation of federal funds to local jurisdictions. Some state and local programs also use SAIPE income and poverty estimates to distribute funds and manage programs. Due to the comprehensive geographic coverage and one-year focus, SAIPE data can be used to analyze geographic variation in poverty and income, as well as changes over time. The purpose of this document is to highlight several key aspects of such analysis. Appended are: (1) Census Regions and Divisions in the United States; (2) Counties by Metro/Micro Area Status; (3) Supplemental Information for School Districts; and (4) Counties Published in the 2009 ACS 1-Year Estimates.

Offshore fish of the Beaufort Sea have not been surveyed since 1977 and no synchronous measures of fish distribution and the oceanographic characteristics of their habitat have been made previously. A survey was conducted during August 2008 in the western Beaufort Sea, Alaska. The distribution and abundance of benthic fish and invertebrates were assessed with standard bottom trawl survey methods. Oceanographic data were collected at each trawl station and at several locations between stations. The dominant benthic taxa, Polar cod (Boreogadus saida), eelpouts (Lycodes sp.), and snow crab (Chionoecetes opilio) were associated with cold (33) water found offshore of the shelf break, derived from the Chukchi Sea. These waters are expected to be high in secondary productivity, such that we hypothesize that the distribution of fish and crab was driven by conditions favorable for successful foraging. Predictions of the impacts of climate change require an understanding of the mechanisms linking the distribution and abundance of marine organisms to their oceanographic habitat. Our study documents the association of dominant benthic fish and invertebrates of the Beaufort Sea with specific water mass types and is thus a step toward this understanding.

Three shipboard surveys were conducted (February 2005-2007), and an echosounder was used to measure the distribution and abundance of krill while simultaneously conducting visual surveys to map seabird and marine mammals. Using a multispecies approach, we test the hypothesis that spatial organization of krill and top predators co-vary according to fine-scale changes in bathymetry in the nearshore marine environment. GAMs are used to examine the effect of sea depth, slope and distance to isobaths on the spatial distribution and abundance of krill and predators. Spatial distribution patterns of krill and predators relate to fine-scale (1-10 km) changes in bathymetry and exhibit cross-shelf gradients in abundance. Krill were concentrated along the shelf-break and abundant within both submarine canyons. Predators exhibited different preferences for locations within the submarine canyon system that relates to their foraging behavior. Penguins concentrated closer to shore and within the head of the east submarine canyon immediately adjacent to a breeding colony. Whales were also concentrated over the head of the east canyon (overlapping with penguins), whereas albatrosses and fur seals were concentrated in the west canyon. Fur seals also showed preference for steep slopes and were concentrated along the shelf-break. Petrels exhibited peaks in abundance throughout both submarine canyons. Owing to their orientation, size and proximity to the coastline, submarine canyons provide important habitat heterogeneity for krill and a variety of predators. This study highlights the multispecies approach for studying spatial ecology of top predators and krill and has implications for marine spatial management of the Scotia Sea.

Coral-poor and coral-rich areas were surveyed at sites with both low (Hawaii Island) and high (Midway Atoll) predator densities, facilitating examination of relations among predator and recruit densities, habitat, and group metrics. Predator and recruit densities varied spatially and temporally, with a sixfold range in total recruit densities among years. Group ( greater than or equal to 2 recruits) metrics varied with time and tracked predator and recruit densities and the proportion of schooling species. Groups often included heterospecifics whose proportion increased with group size. A non-saturating relationship between group size and recruit density suggests that the anti-predator benefits of aggregation exceeded competitive costs.

This paper describes the retrofits and the results of the pre- and post-retrofit assessment of building airtightness, ventilation, and energy use. Building envelope and air distribution systems airtightness were measured using fan pressurization. Air change rates were measured continuously using the tracer gas decay technique. Energy consumption associated with heating and cooling was monitored through measurement of gas consumption by the forced-air furnace for heating and electricity use by the air-conditioning system for cooling. The results of the study show that the retrofits reduced building envelope leakage by about 18% and duct leakage by about 80%. The reduction in the house infiltration rates depended on weather conditions and the manner in which the heating and cooling system was controlled, but in general these rates were reduced by about one third. The energy consumption of the house for heating and cooling was reduced by only about 10%, which is relatively small but not totally unexpected given that infiltration only accounts for a portion of the heating and cooling load.

In the US Atlantic, the smalltooth sawfish (Pristis pectinata) has declined to 1-5% of its abundance in the 1900s, and its core distribution has contracted to southwest Florida. We used 8 polymorphic microsatellite markers to show that this remnant population still exhibits high genetic diversity in terms of average allelic richness (18.23), average alleles per locus (18.75, standard deviation [SD] 6.6) and observed heterozygosity (0.43-0.98). Inbreeding is rare (mean individual internal relatedness = -0.02, SD 0.14; F sub(IS) = -0.011, 95% confidence interval [CI] = -0.039 to 0.011), even though the estimated effective population size (N sub(e)) is modest (250-350, 95% CI = 142-955). Simulations suggest that the remnant smalltooth sawfish population will probably retain >90% of its current genetic diversity over the next century even at the lower estimate of N sub(e). There is no evidence of a genetic bottleneck accompanying last century's demographic bottleneck, and we discuss hypotheses that could explain this. We also discuss features of elasmobranch life history and population biology that could make them less vulnerable than other large marine vertebrates to genetic change associated with reduced population size.

After years of continuous low-level eruptive activity, a major landslide occurred at NW Rota-1 in August 2009, triggered by an unusually large eruption that produced 10 times the acoustic energy of the background level of activity. An anomalous earthquake swarm preceded the eruption, suggesting that the sequence started with a magmatic intrusion and associated faulting beneath the volcano. We quantify the size and extent of the landslide using bathymetric resurveys and interpret the timing of events using data from an in situ hydrophone. This is the first instrumental documentation of an earthquake-eruption-landslide sequence at a submarine volcano, and illustrates the close interaction between magmatic activity and mass wasting events in the growth of undersea arc volcanoes.

However, little is known about whether an advance supplemental brochure will have a similar effect. The research documented in this article serves two purposes: First, this exploratory study uses qualitative data from cognitive interviews conducted with five language groups to understand why a multilingual brochure inserted with an English advance letter might or might not enhance survey participation among non-English-speaking respondents.

The fate of these organic phosphorus compounds in the environment is not well studied. This study presents the first investigation on the sorption of phosphorus (P) in the presence of two model phosphonate compounds, 2-aminothylphosphonoic acid (2-AEP) and phosphonoformic acid (PFA), on marine carbonate sediments. In contrast to other organic P compounds, no significant inorganic phosphate exchange was observed in seawater. P was found to adsorb on the sediment only in the presence of PFA, not 2-AEP. This indicated that sorption of P from phosphonate on marine sediment was compound specific. Compared with inorganic phosphate sorption on the same sediments, P sorption from organic phosphorus is much less in the marine environment. Further study is needed to understand the potential role of the organophosphonate compounds in biogeochemical cycle of phosphorus in the environment.

Part I: Theory and integral formulae AN - 902373050; 15883432 AB - The non-uniqueness of solution and compatibility between the coupled boundary conditions in computing velocity potential and streamfunction from horizontal velocity in a limited domain of arbitrary shape are revisited theoretically with rigorous mathematic treatments. Classic integral formulas and their variants are used to formulate solutions for the coupled problems. In the absence of data holes, the total solution is the sum of two integral solutions. One is the internally induced solution produced purely and uniquely by the domain internal divergence and vorticity, and its two components (velocity potential and streamfunction) can be constructed by applying Green's function for Poisson equation in unbounded domain to the divergence and vorticity inside the domain. The other is the externally induced solution produced purely but non-uniquely by the domain external divergence and vorticity, and the non-uniqueness is caused by the harmonic nature of the solution and the unknown divergence and vorticity distributions outside the domain. By setting either the velocity potential (or streamfunction) component to zero, the other component of the externally induced solution can be expressed by the imaginary (or real) part of the Cauchy integral constructed using the coupled boundary conditions and solvability conditions that exclude the internally induced solution. The streamfunction (or velocity potential) for the externally induced solution can also be expressed by the boundary integral of a double-layer (or single-layer) density function. In the presence of data holes, the total solution includes a data-hole-induced solution in addition to the above internally and externally induced solutions.

The coupling of two facilities has begun to unravel this difficult problem. The NIST Firebrand Generator (NIST Dragon) is an experimental device that can generate a firebrand shower in a safe and repeatable fashion. Since wind plays a critical role in the spread of WUI fires in the USA and urban fires in Japan, NIST has established collaboration with the Building Research Institute (BRI) in Japan. 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 present investigation is aimed at extensively quantifying firebrand penetration through building vents using full scale tests. A structure was placed inside the FRWTF and firebrand showers were directed at the structure using the NIST Dragon. The structure was fitted with a generic building vent, consisting of only a frame fitted with a metal mesh. Six different mesh sizes openings were used for testing. Behind the mesh, four different materials were placed to ascertain whether the firebrands that were able to penetrate the building mesh assembly could ignite these materials. Reduced scale test methods afford the capability to test new vent technologies and may serve as the basis for new standard testing methodologies. As a result, a new experimental facility developed at NIST is presented and is known as the NIST Dragon's LAIR (Lofting and Ignition Research). The NIST Dragon's LAIR has been developed to simulate a wind driven firebrand attack at reduced scale. The facility consists of a reduced scale Firebrand Generator (Baby Dragon) coupled to a bench scale wind tunnel. Finally, a series of full scale experiments were conducted to visualize the flow of firebrands around obstacles placed downstream of the NIST Dragon. Firebrands were observed to accumulate in front of these obstacles at a stagnation plane, as was observed when the structure was used for firebrand penetration through building vent experiments, due to flow recirculation. The accumulation of firebrands at a stagnation plane presents a severe threat to ignitable materials placed near structures.

A concern for fisheries management agencies is the recovery of these benthic invertebrates from removal or mortality from bottom trawling and other commercial fisheries activities. Using a logistic model, observations of available substrate and data from bottom trawl surveys of the Aleutian Islands, Alaska, we estimated recovery rates of sponges and corals following removal. The model predicted the observed sponge and coral catch in bottom trawl surveys relatively accurately (R2=0.38 and 0.46). For sponges, the results show that intrinsic growth rates were slow (r=0.107yr-1). Results show that intrinsic growth rates of corals were also slow (r=0.062yr-1). The best models for corals and sponges were models that did not include the impacts of commercial fishing removals. Subsequent recovery times for both taxa were also predicted to be slow. Mortality of 67% of the initial sponge biomass would recover to 80% of the original biomass after 20 years, while mortality of 67% of the coral biomass would recover to 80% of the original biomass after 34 years. The modeled recovery times were consistent with previous studies in estimating that recovery times were of the order of decades, however improved data from directed studies would no doubt improve parameter estimates and reduce the uncertainty in the model results. Given their role as a major ecosystem component and potential habitat for marine fish, damage and removal of sponges and corals must be considered when estimating the impacts of commercial bottom trawling on the seafloor.

Over the past three decades, numerous monk seal translocations have been conducted with a variety of objectives, including mitigating shark predation and conspecific male aggression, reducing human-seal interactions, and taking advantage of favorable foraging habitats to improve survival. Here, we analyze our cumulative experience with translocation of Hawaiian monk seals. We found a strong correlation between the time seals remained in the vicinity of the release site and their age. Recently weaned pups (with little or no at-sea foraging experience) exhibited high fidelity to release sites commensurate with that shown by untranslocated pups to their birth location. In contrast, juvenile and adult seals tended to stray from their release locations farther and sooner. Nevertheless, when 21 adult male seals were moved more than 1000km from Laysan Island in the Northwestern Hawaiian Islands (NWHI), to the main Hawaiian Islands (MHI), they subsequently dispersed among the MHI; however, only one was observed to return to the NWHI. Translocated seals appeared to survive at rates comparable to seals native to the release site. Outcomes suggest that in most cases the intended objectives of translocations were achieved. Except for one notable case, translocations within the MHI to arrest human-seal interactions were mostly unsuccessful.

The first one assumes that emissions could occur from any land-use grid cell defined in the model as desert. The second emission approach uses an empirically derived algorithm based on satellite observations. To investigate the dust storm features and verify the model performance, a global dataset of Integrated Surface Hourly (ISH) observations has been analyzed to map the spatial distribution and seasonal variation of sand and dust storms. Furthermore, the PM10 concentration data at four stations in Northern China and two stations in Southern Spain, and the AOD data from a station located at the center of the Sahara Desert have been compared with the model results. The spatial distribution of observed dust storm frequency from ISH shows the known high frequency areas located in North Africa, the Middle East, Mongolia and Northwestern China. Some sand and dust storms have also been observed in Australia, Mexico, Argentina, and other sites in South America. Most of the dust events in East Asia occur in the spring, however this seasonal feature is not so evident in other dust source regions. In general, the model reproduces the dust storm frequency for most of the regions for the two emission approaches. Also, a good quantitative performance is achieved at the ground stations in Southern Spain and Western China when using the desert land-use based emissions, although HYSPLIT overestimates the dust concentration at downwind areas of East Asia and underestimates the column in the center of the Saharan Desert. On the other hand, the satellite based emission approach improves the dust forecast performance in the Sahara, but underestimates the dust concentrations in East Asia.

We report on a study of the realities facing a highly female-dominated job, that of waiter in low-end chain restaurants. Through interviews with managers at 16 sites of two international restaurant chains located in Seattle, Washington and Chicago, Illinois, we examined how the gender and family caregiver compositions of waiter workforces intersect with private employers' practices related to waiter wages, fringe benefits, and staffing and scheduling and preferred job qualifications, on the one hand; and with mandated minimum wage regulations, on the other. Male waiters were most heavily concentrated in the chain with more generous benefits and input into scheduling, while the largest proportions of women were found in the chain offering few or no benefits and little scheduling control. Sites with the most waiter-caregivers came from both chains but were mostly in Seattle, aligning with a US state policy context assuring a higher minimum wage. Paralleling those findings, we observed that managers in especially male-heavy settings stressed intellectual and experience qualifications for waiter positions, while within more female and dependent caregiver employing sites they prioritized factors such as personality and 'good hygiene.'

We analyzed daytrips only. Our estimates from the models ranged from $32 to $142/trip/household or about $131 to $582/season/household (2008$). The variation was due to differences in the value of time. The average household size was 1.66. We found that the valuation results were sensitive to the inclusion of covariates in the model. Our results are useful for damage assessments and benefit-cost analyses where birdwatching is affected. Adapted from the source document.

Efforts to establish tsunami warning systems to protect life and property began in the Pacific after the 1946 Aleutian Islands tsunami caused casualties in Hawaii. Seismic and sea level data were used by a central control center to evaluate tsunamigenic potential and then issue alerts and warnings. The ensuing events of 1952, 1957, and 1960 tested the new system, which continued to expand and evolve from a United States system to an international system in 1965. The Tsunami Warning System in the Pacific (ITSU) steadily improved through the decades as more stations became available in real and near-real time through better communications technology and greater bandwidth. New analysis techniques, coupled with more data of higher quality, resulted in better detection, greater solution accuracy, and more reliable warnings, but limitations still exist in constraining the source and in accurately predicting propagation of the wave from source to shore. Tsunami event data collected over the last two decades through international tsunami science surveys have led to more realistic models for source generation and inundation, and within the warning centers, real-time tsunami wave forecasting will become a reality in the near future. The tsunami warning system is an international cooperative effort amongst countries supported by global and national monitoring networks and dedicated tsunami warning centers; the research community has contributed to the system by advancing and improving its analysis tools. Lessons learned from the earliest tsunamis provided the backbone for the present system, but despite 45 years of experience, the 2004 Indian Ocean tsunami reminded us that tsunamis strike and kill everywhere, not just in the Pacific. Today, a global intergovernmental tsunami warning system is coordinated under the United Nations. This paper reviews historical tsunamis, their warning activities, and their sea level records to highlight lessons learned with the focus on how these insights have helped to drive further development of tsunami warning systems and their tsunami warning centers. While the international systems do well for teletsunamis, faster detection, more accurate evaluations, and widespread timely alerts are still the goals, and challenges still remain to achieving early warning against the more frequent and destructive local tsunamis.

ComMIT is designed for ease of use, and allows dissemination of results to the community while addressing concerns associated with proprietary issues of bathymetry and topography. It uses initial conditions from a precomputed propagation database, has an easy-to-interpret graphical interface, and requires only portable hardware. ComMIT was initially developed for Indian Ocean countries with support from the United Nations Educational, Scientific, and Cultural Organization (UNESCO), the United States Agency for International Development (USAID), and the National Oceanic and Atmospheric Administration (NOAA). To date, more than 60 scientists from 17 countries in the Indian Ocean have been trained and are using it in operational inundation mapping.

Sounds included echolocation clicks and burst pulses. Echolocation clicks were grouped into three categories, a 15 kHz click (n=106), a 25 kHz click (n=136), and a 25 kHz pulse with a frequency-modulated upsweep (n=70). The 15 and 25 kHz clicks were relatively short (181 and 144 ms, respectively); the longer 25 kHz upswept pulse was 288 ms. Burst pulses were long (0.5 s) click trains with approximately 240 clicks/s.

The influence of various material properties (thickness, thermal conductivity, specific heat, absorption of infrared radiation, heat of reaction) on mass loss history is assessed, via their effect on the ignition time, average MLR, peak MLR, and time to peak. The two codes predict the influence of material parameters on the MLR in the order of decreasing importance: heat of reaction, thickness, specific heat, absorption coefficient, thermal conductivity, and activation energy of the polymer decomposition. Changes in the material properties also influence the MLR curves by switching the sample from thermally thick to thermally thin. The two numerical codes are generally in very good agreement for their predictions of the MLR vs time curves, except when in-depth absorption of radiation was important.

The earthquake generated a tsunami that propagated across the Tasman Sea and was detected in New Zealand, Australia and as far away as the US West coast. Small boats close to the epicenter were placed in jeopardy, but no significant damage was observed despite a measured run-up height of 2.3 m in one of the Sounds in close proximity to the source (Wilson in GNS Science Report 46:62 2009). Peak-to-trough tsunami heights of 55 cm were measured at Southport, Tasmania and a height of 1 m was measured in Jackson Bay, New Zealand. The International Tsunami Symposium provided an ideal venue for illustration of the value of immediate real-time assessment and provided an opportunity to further validate the real time forecasting capabilities with the scientific community in attendance. A number of agencies with responsibility for tsunami forecast and/or warning, such as the NOAA Center for Tsunami Research, the Pacific Tsunami Warning Center, GNS Science in New Zealand, the Australian Bureau of Meteorology and the European Commission Joint Research Centre were all represented at the meeting and were able to demonstrate the use of state of the art numerical models to assess the tsunami potential and provide warning as appropriate.

These maps represent an improvement over previous efforts, as they are based on the most recent descriptions of potential tsunami sources, apply recently updated numerical modeling techniques, and cover previously unmapped regions of the State. Since the maps are based on deterministic rather than probabilistic modeling, they are only intended for emergency preparedness and evacuation planning and are not to be used in engineering siting studies. The California maps cover a greater coastal area than any other US State. To be helpful, the maps need to be integrated into a consistent statewide hazard-planning framework. Indeed, tsunami preparedness in California was tested on several occasions over the past 5 years, i.e., during the 14 June 2005 event, about 90 miles SW of Crescent City, the 15 November 2006 Kuril Islands, and the 27 February 2010 Chile earthquake. We discuss briefly the State's response as these events unfolded.

We propose that observations of such cracking can be used as a diagnostic tool for predicting bite force and inferring tooth function in living and fossil mammals. Laboratory tests on model tooth structures and extracted human teeth in simulated biting identify the principal fracture modes in enamel. Examination of museum specimens reveals the presence of similar fractures in a wide range of vertebrates, suggesting that cracks extended during ingestion or mastication. The use of "fracture mechanics" from materials engineering provides elegant relations for quantifying critical bite forces in terms of characteristic tooth size and enamel thickness. The role of enamel microstructure in determining how cracks initiate and propagate within the enamel (and beyond) is discussed. The picture emerges of teeth as damage-tolerant structures, full of internal weaknesses and defects and yet able to contain the expansion of seemingly precarious cracks and fissures within the enamel shell. How the findings impact on dietary pressures forms an undercurrent of the study.

[Part 1 of 1] T2 - GENERIC ANNUAL CATCH LIMITS/ACCOUNTABILITY MEASURES AMENDMENT FOR THE GULF OF MEXICO FISHERY MANAGEMENT COUNCILS RED DRUM, REEF FISH, SHRIMP, CORAL AND CORAL REEFS, FISHERY MANAGEMENT PLANS. AN - 916687935; 15119-2_0001 AB - PURPOSE: The specification of mechanisms to set acceptable biological catch (ABC), annual catch limits (ACLs), annual catch targets (ACTs), and accountability measures (AMs) for four fisheries in the Gulf of Mexico is proposed. Specifically, this generic EIS would amend the Reef Fish Resources, Red Drum, Shrimp, and Coral and Coral Reefs Fishery Management Plans (FMPs). There are fifty stocks in the Gulf of Mexico FMPs that are subject to action in this amendment. Four stocks are currently listed as overfished and undergoing overfishing: gag, gray triggerfish, greater amberjack, and red snapper. Ten stocks are classified as not undergoing overfishing, but overfished status is unknown or undefined (red drum, goliath grouper, Nassau grouper, royal red shrimp, stone crabs, and five classifications of corals). Five stocks are also classified as neither undergoing overfishing nor overfished (black grouper, mutton snapper, red grouper, vermilion snapper, and yellowtail snapper). In addition, a recently completed assessment on yellowedge grouper concluded that this stock is neither overfished not undergoing overfishing. For the remaining 30 stocks, classifications have not been determined, either because there is no stock assessment, or because the assessment was inconclusive. Long-term measures proposed in this final EIS include: 1) transfer management of selected species to state or federal agencies; 2) remove selected stocks from the Reef Fish FMP; 3) develop species groupings to reduce the risk of exceeding catch limits; 4) describe the process by which ABC will be specified to account for scientific uncertainty; 5) develop initial specification of ACLs procedures to address for management uncertainty; 6) develop standardized framework procedures for implementing management changes pursuant to the provisions of the FMP; 7) establish ACLs and/or annual catch targets (ACTs) for species that do not currently have harvest quotas; and 8) establish AMs for each of the catch frameworks. Preferred alternatives include: transfer of responsibility for Nassau grouper to the South Atlantic Fishery Management Council (FMC); removal of species that have average annual landings of 15,000 pounds or less with certain exceptions; transfer of responsibility for octocorals to the South Atlantic FMC; and species groupings for stocks that share common habitat and are caught with the same gear, in the same area, and at the same time. POSITIVE IMPACTS: The specification of overfishing limits, ACLs, and AMs would comply with the reauthorized Magnuson-Stevens Act requirements. Implementation is expected to prevent overfishing and achieve optimum yield while minimizing to the extent practicable adverse social and economic effects. NEGATIVE IMPACTS: The proposed actions could reduce the harvest of species in the Reef Fish Resources, Shrimp, and Coral and Coral Reefs FMPs resulting in adverse socioeconomic effects to vulnerable fishing communities along the coasts of Florida, Louisiana, and Texas. Management measures could increase administrative burden. LEGAL MANDATES: Magnuson Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

[Part 1 of 1] T2 - AMENDMENT 2 TO THE FISHERY MANAGEMENT PLAN FOR THE QUEEN CONCH FISHERY AND AMENDMENT 5 TO THE FISHERY MANAGEMENT PLAN FOR THE REEF FISH FISHERY, PUERTO RICO AND THE U.S. VIRGIN ISLANDS. AN - 916687156; 15120-3_0001 AB - PURPOSE: The amendment of the fishery management plans (FMPs) for reef fish and queen conch in the U.S. Caribbean to bring those fisheries into compliance with the 2007 revisions to the Magnuson-Stevens Fishery Conservation and Management Act (MSA) is proposed. Caribbean queen conch, parrotfish, and several species within the Caribbean snapper and grouper families are currently classified as subject to overfishing. Six actions included in the amendment are analyzed in this final EIS. Action 1 would amend the grouper and snapper stock complexes in the reef fish fishery management unit (FMU). Action 2 would revise management reference points to transition U.S. Caribbean reef fish and queen conch management from that established in the Comprehensive Sustainable Fisheries Amendment (SFA) of 2005 to that mandated by the MSA. Action 3 would work in concert with Action 2 and would provide the specific details regarding the distribution and numerical value of annual catch limits (ACLs) for the various island groups, including Puerto Rico, St. Croix in the United States Virgin Islands (USVI), and the island group of St. Thomas and St. John in the USVI. Action 4 would implement management measures with specific emphasis on harvest prohibitions for three parrotfish species (midnight, blue, and rainbow) and would impose recreational bag limits for reef fish. Action 5 would implement guidelines for triggering accountability measures (AMs) and for applying those AMs. Finally, Action 6 would establish framework provisions separately for reef fish and queen conch. Sub-actions included in Action 1 would address the grouper complex with regard to misty, yellowedge, and black grouper, and creole fish, and the snapper complex with regard to the cardinal snapper and wenchman species. For Actions 2 and 3, the preferred alternative would redefine management reference points or proxies for the snapper, grouper, and parrotfish complexes based on the longest time series of pre-Comprehensive SFA catch data that is considered to be reliable across all islands and define geographic boundaries between each island group. Division and management of ACLs by island group would be based on the preferred reference point time series using an equidistant method for dividing the U.S. Exclusive Economic Zone (EEZ) among islands. Preferred alternatives for Action 4 would establish an overall aggregate bag limit that allows a fisher a total of 10 fish per day including not more than two parrotfish and a vessel limit of not more than 30 fish per day of which no more than six can be parrotfish. Fishing for or possessing midnight parrotfish, blue parrotfish, and rainbow parrotfish would be prohibited in the EEZ. For Action 5, preferred alternatives would provide for AMs to be triggered if the ACL is exceeded based on a single year of landings, the average of the two most recent years of landings, or an average of the three most recent years of landings. Alternatives for amending the framework procedures for the reef fish and queen conch FMPs would provide a mechanism to expeditiously adjust the reference points and management measures. POSITIVE IMPACTS: In concert, the proposed actions would provide a basic foundation for place-based reef fish and queen conch fisheries management in the U.S. Caribbean. Allocation management is expected to result in better distribution of harvest among island groups and decreased likelihood of area-specific overharvest. NEGATIVE IMPACTS: Available USVI landings data do not allow for effective management of snapper at the unit level in USVI. Race for quota could still occur within the commercial and recreational sectors and could lead to overcapitalization of fishing assets. More restrictive catch levels would result in greater administrative burden due to more frequent incidents of overharvest necessitating increased frequency of management actions.

Preparation date: October 28, 2011 N1 - Last updated - 2012-01-19 ER - TY - RPRT T1 - AMENDMENT 2 TO THE FISHERY MANAGEMENT PLAN FOR THE QUEEN CONCH FISHERY AND AMENDMENT 5 TO THE FISHERY MANAGEMENT PLAN FOR THE REEF FISH FISHERY, PUERTO RICO AND THE U.S. VIRGIN ISLANDS. AN - 913430205; 15120 AB - PURPOSE: The amendment of the fishery management plans (FMPs) for reef fish and queen conch in the U.S. Caribbean to bring those fisheries into compliance with the 2007 revisions to the Magnuson-Stevens Fishery Conservation and Management Act (MSA) is proposed. Caribbean queen conch, parrotfish, and several species within the Caribbean snapper and grouper families are currently classified as subject to overfishing. Six actions included in the amendment are analyzed in this final EIS. Action 1 would amend the grouper and snapper stock complexes in the reef fish fishery management unit (FMU). Action 2 would revise management reference points to transition U.S. Caribbean reef fish and queen conch management from that established in the Comprehensive Sustainable Fisheries Amendment (SFA) of 2005 to that mandated by the MSA. Action 3 would work in concert with Action 2 and would provide the specific details regarding the distribution and numerical value of annual catch limits (ACLs) for the various island groups, including Puerto Rico, St. Croix in the United States Virgin Islands (USVI), and the island group of St. Thomas and St. John in the USVI. Action 4 would implement management measures with specific emphasis on harvest prohibitions for three parrotfish species (midnight, blue, and rainbow) and would impose recreational bag limits for reef fish. Action 5 would implement guidelines for triggering accountability measures (AMs) and for applying those AMs. Finally, Action 6 would establish framework provisions separately for reef fish and queen conch. Sub-actions included in Action 1 would address the grouper complex with regard to misty, yellowedge, and black grouper, and creole fish, and the snapper complex with regard to the cardinal snapper and wenchman species. For Actions 2 and 3, the preferred alternative would redefine management reference points or proxies for the snapper, grouper, and parrotfish complexes based on the longest time series of pre-Comprehensive SFA catch data that is considered to be reliable across all islands and define geographic boundaries between each island group. Division and management of ACLs by island group would be based on the preferred reference point time series using an equidistant method for dividing the U.S. Exclusive Economic Zone (EEZ) among islands. Preferred alternatives for Action 4 would establish an overall aggregate bag limit that allows a fisher a total of 10 fish per day including not more than two parrotfish and a vessel limit of not more than 30 fish per day of which no more than six can be parrotfish. Fishing for or possessing midnight parrotfish, blue parrotfish, and rainbow parrotfish would be prohibited in the EEZ. For Action 5, preferred alternatives would provide for AMs to be triggered if the ACL is exceeded based on a single year of landings, the average of the two most recent years of landings, or an average of the three most recent years of landings. Alternatives for amending the framework procedures for the reef fish and queen conch FMPs would provide a mechanism to expeditiously adjust the reference points and management measures. POSITIVE IMPACTS: In concert, the proposed actions would provide a basic foundation for place-based reef fish and queen conch fisheries management in the U.S. Caribbean. Allocation management is expected to result in better distribution of harvest among island groups and decreased likelihood of area-specific overharvest. NEGATIVE IMPACTS: Available USVI landings data do not allow for effective management of snapper at the unit level in USVI. Race for quota could still occur within the commercial and recreational sectors and could lead to overcapitalization of fishing assets. More restrictive catch levels would result in greater administrative burden due to more frequent incidents of overharvest necessitating increased frequency of management actions. The aggregate bag limit for snapper, grouper, and parrotfish would have adverse socioeconomic effects for recreational and subsistence fishermen.

AN - 913430204; 15119 AB - PURPOSE: The specification of mechanisms to set acceptable biological catch (ABC), annual catch limits (ACLs), annual catch targets (ACTs), and accountability measures (AMs) for four fisheries in the Gulf of Mexico is proposed. Specifically, this generic EIS would amend the Reef Fish Resources, Red Drum, Shrimp, and Coral and Coral Reefs Fishery Management Plans (FMPs). There are fifty stocks in the Gulf of Mexico FMPs that are subject to action in this amendment. Four stocks are currently listed as overfished and undergoing overfishing: gag, gray triggerfish, greater amberjack, and red snapper. Ten stocks are classified as not undergoing overfishing, but overfished status is unknown or undefined (red drum, goliath grouper, Nassau grouper, royal red shrimp, stone crabs, and five classifications of corals). Five stocks are also classified as neither undergoing overfishing nor overfished (black grouper, mutton snapper, red grouper, vermilion snapper, and yellowtail snapper). In addition, a recently completed assessment on yellowedge grouper concluded that this stock is neither overfished not undergoing overfishing. For the remaining 30 stocks, classifications have not been determined, either because there is no stock assessment, or because the assessment was inconclusive. Long-term measures proposed in this final EIS include: 1) transfer management of selected species to state or federal agencies; 2) remove selected stocks from the Reef Fish FMP; 3) develop species groupings to reduce the risk of exceeding catch limits; 4) describe the process by which ABC will be specified to account for scientific uncertainty; 5) develop initial specification of ACLs procedures to address for management uncertainty; 6) develop standardized framework procedures for implementing management changes pursuant to the provisions of the FMP; 7) establish ACLs and/or annual catch targets (ACTs) for species that do not currently have harvest quotas; and 8) establish AMs for each of the catch frameworks. Preferred alternatives include: transfer of responsibility for Nassau grouper to the South Atlantic Fishery Management Council (FMC); removal of species that have average annual landings of 15,000 pounds or less with certain exceptions; transfer of responsibility for octocorals to the South Atlantic FMC; and species groupings for stocks that share common habitat and are caught with the same gear, in the same area, and at the same time. POSITIVE IMPACTS: The specification of overfishing limits, ACLs, and AMs would comply with the reauthorized Magnuson-Stevens Act requirements. Implementation is expected to prevent overfishing and achieve optimum yield while minimizing to the extent practicable adverse social and economic effects. NEGATIVE IMPACTS: The proposed actions could reduce the harvest of species in the Reef Fish Resources, Shrimp, and Coral and Coral Reefs FMPs resulting in adverse socioeconomic effects to vulnerable fishing communities along the coasts of Florida, Louisiana, and Texas. Management measures could increase administrative burden. LEGAL MANDATES: Magnuson Fishery Conservation and Management Act of 1976 (16 U.S.C. 1801 et seq.).

In the absence of cross section data, assumed or parameterized cross section shapes are often used. The effects of parameterized cross sections are evaluated in this study by developing a modeling framework that externally couples a spatially distributed hydrologic model, HL-RDHM, with a one-dimensional unsteady hydraulic model, HEC-RAS. The evaluation emphasizes the effects of parameterized cross sections on simulated flows by focusing the analysis on the portion of the basin's main stream reach where detailed cross section data and observed streamflows (at both ends of the reach) are available, and by developing and testing three cross section scenarios. The scenarios are designed to increase sequentially, in a stepwise fashion, the complexity of the parameterized cross section, starting with a single roughness parameter and channel power law cross section shape and then including additional power law or roughness parameters. This is done stepwise to help distinguish the effects associated with each parameterization, and decide the required level of cross section detail. The scenario simulations are evaluated using split sampling, changes in measures of performance and hydrograph agreement, hypothesis tests on Nash-Sutcliffe values, and overall predictive uncertainty. The coupling framework is applied to the Blue and Illinois River basins, in Oklahoma, US. Overall, we found that in these basins the coupling tends to improve predictions when dynamic wave routing and floodplain cross section geometry are considered concurrently. For this scenario, we found that on average typical measures of model performance may be improved and, based on a quantitative and qualitative assessment, uncertainty may be reduced. We also found that dynamic wave routing does not tend to perform better than kinematic wave routing for the most basic scenarios with a single power law cross section shape. Further, results indicate that the distributed hydrologic model performance at the main outlet and at the upstream boundary of the hydraulic model, and the relative contribution of lateral inflows, are key factors that need to be considered when deciding the applicability of the coupled framework to other basins. In the future, to effectively use resources, it will be beneficial to automate the coupling and accompany its application with a priori criteria for selecting those basins where benefits are most likely.

[Part 1 of 1] T2 - FAGATELE BAY NATIONAL MARINE SANCTUARY MANAGEMENT PLAN, AMERICAN SAMOA. AN - 912099719; 15111-4_0001 AB - PURPOSE: A new management plan for Fagatele Bay National Marine Sanctuary (FBNMS) in American Samoa is proposed. The sanctuary was designated in 1986 to protect and preserve an example of a pristine tropical marine habitat and coral reef terrace ecosystem of exceptional biological productivity. The American Samoa territory is composed of five volcanic islands and two small remote coral atolls. Fagatele Bay is located along the southwestern coast of Tutuila Island and is the smallest and most remote of the national marine sanctuaries as well as the only one in the Southern Hemisphere. FBNMS encompasses 0.25 square miles of reef flat, shallow reef, and steep slopes plunging down to 600 feet within a naturally protected bay surrounded by steep cliffs. Fagatele Bays coral reefs provide habitat for at least 271 species of fishes, 168 species of coral and at least 1,400 species of algae and invertebrates. Marine mammals and sea turtles may also be found in or near the sanctuary and surrounding environs. This draft EIS analyzes a No Action Alternative and four action alternatives. The No Action Alternative would continue current management under the original 1984 plan. Under Alternative 1, an updated management plan would include new goals and the addition of a management permit. Alternative 2 would expand FBNMS to two sanctuary units, while Alternatives 3A, 3B, 4A and 4B would expand the sanctuary to five or six sanctuary units with a suite of habitat protection, fishery, and other regulations. The preferred alternative (Alternative 3B) would incorporate five additional units including the Larsen Bay unit located along the southern coast of Tutuila, Aunuu Island located just off the southeastern shore of Tutuila, and Tau Island, Rose Atoll, and Swains Island. The Samoan name for Rose Atoll is Muliava and is the proposed name for this unit. The Muliava unit consists solely of federal waters, but would not include the land or the 1,600 acres of reef habitat of the Rose Atoll National Wildlife Refuge. All of the other units would occur completely within territorial waters, encompassing both shallow reef and deep waters, and extend to the mean high water line of the coast. The proposed action would increase the overall size of the sanctuary from 0.25 square miles to 13,568.5 square miles, with the majority of this expansion (99 percent) from the designation of the marine areas of the Rose Atoll Marine National Monument. The name of the FBNMS would be changed to the American Samoa National Marine Sanctuary. POSITIVE IMPACTS: The plan would chart the course for FBNMS over the next five to 10 years. Alternatives 2, 3, and 4 would provide more protection for marine resources, additional protection for cultural resources, and new opportunities for research through both increasing the total size of the sanctuary and proposing additional regulations. NEGATIVE IMPACTS: Some adverse impacts to fisheries would result from use restrictions within the sanctuary units. Land-based operations including agricultural activities, piggery operations, utility discharge, and construction may experience impacts if they cause pollutants to enter sanctuary waters that violate the discharge prohibition. Adverse economic impacts, specifically the loss of revenue due to fishery restrictions, are expected to be small due to the diminishing level of nearshore fisheries and the small size of reef area that is closed to all fishing.

Alternative 2 would expand FBNMS to two sanctuary units, while Alternatives 3A, 3B, 4A and 4B would expand the sanctuary to five or six sanctuary units with a suite of habitat protection, fishery, and other regulations. The preferred alternative (Alternative 3B) would incorporate five additional units including the Larsen Bay unit located along the southern coast of Tutuila, Aunuu Island located just off the southeastern shore of Tutuila, and Tau Island, Rose Atoll, and Swains Island. The Samoan name for Rose Atoll is Muliava and is the proposed name for this unit. The Muliava unit consists solely of federal waters, but would not include the land or the 1,600 acres of reef habitat of the Rose Atoll National Wildlife Refuge. All of the other units would occur completely within territorial waters, encompassing both shallow reef and deep waters, and extend to the mean high water line of the coast. The proposed action would increase the overall size of the sanctuary from 0.25 square miles to 13,568.5 square miles, with the majority of this expansion (99 percent) from the designation of the marine areas of the Rose Atoll Marine National Monument. The name of the FBNMS would be changed to the American Samoa National Marine Sanctuary. POSITIVE IMPACTS: The plan would chart the course for FBNMS over the next five to 10 years. Alternatives 2, 3, and 4 would provide more protection for marine resources, additional protection for cultural resources, and new opportunities for research through both increasing the total size of the sanctuary and proposing additional regulations. NEGATIVE IMPACTS: Some adverse impacts to fisheries would result from use restrictions within the sanctuary units. Land-based operations including agricultural activities, piggery operations, utility discharge, and construction may experience impacts if they cause pollutants to enter sanctuary waters that violate the discharge prohibition. Adverse economic impacts, specifically the loss of revenue due to fishery restrictions, are expected to be small due to the diminishing level of nearshore fisheries and the small size of reef area that is closed to all fishing.

Several flights of NOAA and NCAR research aircraft were dedicated to characterizing anthropogenic emissions over Houston. We present results from an inverse modeling technique that uses three atmospheric transport models and these aircraft observations to assess and improve existing emission inventories. We used inverse modeling techniques to improve the spatial and temporal emissions' distribution of CO, NOy, and SO2 predicted by the 4 km resolution U.S. Environmental Protection Agency (EPA) National Emission Inventory (NEI) for 2005. Differences between the prior and posterior inventories are discussed in detail. In September 2006, we found that the prior daytime CO emissions in the Houston urban area have to be reduced by 41% +/- 8%. Over the Houston Ship Channel, where industrial emissions are predominant, the prior emissions have to be decreased by 43% +/- 5% for CO and 51% +/- 5% for NOy. Prior NOy emissions from other major ports around Houston also have to be reduced, probably owing to uncertain nearshore ship emissions in the EPA NEI inventory. Using the measurements from the two field campaigns, we assessed the emissions' variability between August 2000 and September 2006. Daytime CO emissions from the Houston urban area have decreased by 8% +/- 3%, while the NOy emissions have increased by 20% +/- 6%. In the Houston Ship Channel, daytime NOy emissions have increased by 13% +/- 7%. Our results show qualitative consistencies with known changes in Houston emissions' sources.

16000951 AB - The bivalve Pacific geoduck (Panopea generosa) has been used in the eastern North Pacific Ocean to create proxies for environmental factors such as temperature and oceanographic conditions. This type of research depends upon accurate age determination of Pacific geoducks, which historically was based on shell growth-increment counts. A recent study comparing age estimates generated by the dendrochronology (tree-ring science) procedure of crossdating to those estimated from growth-increment counts found a significant difference between the methods for geoduck older than 30years. Compared to the traditional age determination method of counting growth increments, the crossdating method estimates a greater longevity in this species, with some individuals living in excess of 150years. In the present study, the accuracy of each method was independently assessed using bomb-produced radiocarbon (14C) techniques. Specimens whose birth years were estimated to be within the era of the bomb-produced marine 14C increase and where the differences between ages estimated by the two methods were greatest were selected for 14C analysis. The difference between age estimates from traditional growth-increment counts and those from crossdating was evaluated using their respective 14C chronologies in comparisons to a reference chronology as a standard. The comparisons relied on Bayesian nonlinear models using Markov Chain Monte Carlo simulation. This method of analysis showed that with a 50% probability geoducks were aged correctly when using the crossdating method, compared to the growth increment counts which had a 50% probability of underestimating the age by 4years. Therefore, the crossdated age estimates were found to be more accurate than increment counts. Furthermore, these results provide new confidence in using Pacific geoduck biochronologies for paleoclimate and paleoenvironmental reconstruction.

Establishment-level data from three Censuses of Manufactures are used to estimate 3-factor Cobb-Douglas production functions that include a measure of the stringency of environmental regulation faced by manufacturing plants. In contrast to previous studies, this paper examines effects on plants in all manufacturing industries, not just those in 'dirty' industries. Further, this paper employs spatial-temporal variation in environmental compliance costs to identify effects, using a time-varying county-level index that is based on multiple years of establishment-level data from the Pollution Abatement Costs and Expenditures survey and the Annual Survey of Manufactures. Results suggest that, for the average manufacturing plant, there is no statistically significant effect on productivity of being in a county with higher environmental compliance costs. For the average plant, the main effect of environmental regulation may not be in the spatial and temporal dimensions.

Using the proposed method, two sets of UNIFAC group-group interaction parameters for 52 main groups are produced based on published vapor-liquid equilibrium (VLE), excess enthalpies, and activity coefficients at infinite dilution critically evaluated on-demand with the NIST ThermoData Engine (TDE) software. The new regression analysis method includes the use of evaluated uncertainties in assessment of quality factors evaluated on the basis of consistency tests for VLE data. Validity and effectiveness of the proposed method are discussed.

Here we use observations from 1970-2010 (also extending back to 1950) and numerical model experiments to show that the Atlantic warm pool (AWP) - a large body of warm water comprised of the Gulf of Mexico, the Caribbean Sea and the western tropical North Atlantic - plays an important role in the hurricane track. An eastward expansion of the AWP shifts the hurricane genesis location eastward, decreasing the possibility for a hurricane to make landfall. A large AWP also induces barotropic stationary wave patterns that weaken the North Atlantic subtropical high and produce the eastward steering flow anomalies along the eastern seaboard of the United States. Due to these two mechanisms, hurricanes are steered toward the northeast without making landfall in the United States. Although the La Nina event in the Pacific may be associated with the increased number of Atlantic hurricanes, its relationship with landfalling activity has been offset in 2010 by the effect of the extremely large AWP.

[Part 3 of 3] T2 - TRIDENT SUPPORT FACILITIES EXPLOSIVES HANDLING WHARF (EHW-2), NAVAL BASE KITSAP BANGOR, SILVERDALE, KITSAP COUNTY, WASHINGTON (DRAFT SUPPLEMENT TO THE DRAFT ENVIRONMENTAL IMPACT STATEMENT OF MARCH 2011). AN - 910376280; 15097-9_0003 AB - PURPOSE: The construction and operation of a second explosives handling wharf (EHW-2) at Naval Base Kitsap Bangor (NBK Bangor) in Silverdale, Kitsap County, Washington are proposed. NBK Bangor is located on the Hood Canal approximately 20 miles west of Seattle and provides berthing and support services to TRIDENT submarines. The entirety of NBK Bangor, including the land areas and adjacent waters in Hood Canal, is restricted from general public use. The EHW-2 would be adjacent to but separate from the existing EHW and would consist of the wharf proper and access trestles. The draft EIS of March 2011 evaluated a No Action Alternative and five action alternatives consisting of combinations of two access trestle layouts (separate and combined) and three wharf configurations (conventional pile-supported, large pile, and floating). The Combined Trestle, Large Pile Wharf Alternative (Alternative 1), was identified as the preferred alternative. This draft supplement addresses the methodology used to assess the potential for injurious impacts to the marbled murrelet from impact pile driving; the construction and operation of four new facilities proposed to be built to replace the functions of five buildings to be demolished and the associated infrastructure; and compensatory mitigation options under consideration to offset unavoidable impacts to aquatic resources. The project would also include construction of an upland road, an abutment where the trestles connect to the shore, and an upland construction staging area. Approximately 20 existing facilities and/or structures in proximity to the proposed structure would be modified or demolished to comply with safety and security activity requirements. The marine and terrestrial construction would occur over approximately four years. In-water work would be subject to timing and seasonal restrictions to avoid and minimize impacts. Construction would typically occur six days per week, but could occur seven days per week. POSITIVE IMPACTS: A new wharf would support future program requirements for the eight submarines homeported at NBK Bangor and for the TRIDENT II strategic weapons system. Implementation would provide a substantial economic benefit to the local and regional economy through the creation of 4,370 direct jobs and 1,970 indirect and induced jobs. Total economic output to the region would be in excess of $722 million. NEGATIVE IMPACTS: Upland construction would result in disturbance of 6.6 vegetated acres and loss of 0.18 acre of wetland. Construction would generate noise, turbidity, and air pollutant emissions. Long term impacts would include loss and shading of marine habitat including eelgrass, macroalgae and benthic community, and interference with migration of juvenile salmon. All action alternatives would have the potential to adversely affect fish (including tribal treaty-reserved resources), birds, and marine mammals. Species that may be adversely affected include Hood Canal summer-run chum salmon, Puget Sound Chinook salmon, Puget Sound steelhead, bull trout, bocaccio, yelloweye rockfish, canary rockfish, Steller sea lion, and marbled murrelet. Construction would alter the setting of the existing EHW, which is eligible for listing on the National Register of Historic Places.

Preparation date: October 7, 2011 N1 - Last updated - 2011-12-06 ER - TY - JOUR T1 - Oceanic Diet and Distribution of Haplotypes for the Green Turtle, Chelonia mydas, in the Central North Pacific AN - 954659806; 16387528 AB - A diet analysis was conducted on the gastrointestinal contents of 10 oceanic green turtles, Chelonia mydas, collected as bycatch mortalities in pelagic fisheries. Size distribution of the green turtles ranged from 30 to 70 cm curved carapace length (CCL). Prey items found indicated pelagic green turtles to be carnivorous with some omnivorous tendencies, foraging within the first 100 m of the water column. Most frequent identifiable prey items were Zooplankton, pelagic crustaceans, and mollusks (listed in order of frequency of occurrence, which ranged from 80% to 40% frequency): Pyrosoma spp., Lepas spp. (goose barnacles), amphipods, Carinaria spp. (sea snails), and Cavolinia spp. (sea butterflies). Other coelenterates such as salps, ctenophores, and cnidarians (jellyfish) were also identified. Plastics and anthropogenic debris were commonly found (70% frequency, mean = 4% of gastrointestinal content by volume). The turtles examined consisted of two distinct morphotypes corresponding to the central Pacific and the eastern Pacific green turtle populations. Genetic analysis confirmed turtles of the central Pacific morphotype to be of Hawaiian origin and at least one of the eastern Pacific morphotype turtles to have a mtDNA haplotype found in the population nesting in the Revillagigedo archipelago off Mexico. Other eastern Pacific morphotypical turtles had a different common Mexican haplotype found among the nesting populations throughout Mexico and the Galapagos. Turtles of the central Pacific morphotype were distributed north of the Hawaiian Islands, and turtles of the eastern Pacific morphotype were all encountered south of Hawai'i, suggesting a dichotomy in the oceanic distribution of these two populations. Our records of green turtles as large as 70 cm CCL in pelagic waters suggest that some green turtles, mainly those with eastern Pacific green turtle morphology and mtDNA haplotype, delay their recruitment to nearshore (neritic) habitats or move back and forth between neritic and open ocean waters as adults.

The CFSR represents a new generation of reanalysis effort with first guess from a coupled atmosphere-ocean-sea ice-land forecast system. This study focuses on the analysis of climate variability for a set of surface variables including precipitation, surface air 2-m temperature (T2m), and surface heat fluxes. None of these quantities are assimilated directly and thus an assessment of their variability provides an independent measure of the accuracy. The CFSR is compared with observational estimates and three previous reanalyses (the NCEP/NCAR reanalysis or R1, the NCEP/DOE reanalysis or R2, and the ERA40 produced by the European Centre for Medium-Range Weather Forecasts). The CFSR has improved time-mean precipitation distribution over various regions compared to the three previous reanalyses, leading to a better representation of freshwater flux (evaporation minus precipitation). For interannual variability, the CFSR shows improved precipitation correlation with observations over the Indian Ocean, Maritime Continent, and western Pacific. The T2m of the CFSR is superior to R1 and R2 with more realistic interannual variability and long-term trend. On the other hand, the CFSR overestimates downward solar radiation flux over the tropical Western Hemisphere warm pool, consistent with a negative cloudiness bias and a positive sea surface temperature bias. Meanwhile, the evaporative latent heat flux in CFSR appears to be larger than other observational estimates over most of the globe. A few deficiencies in the long-term variations are identified in the CFSR. Firstly, dramatic changes are found around 1998-2001 in the global average of a number of variables, possibly related to the changes in the assimilated satellite observations. Secondly, the use of multiple streams for the CFSR induces spurious jumps in soil moisture between adjacent streams. Thirdly, there is an inconsistency in long-term sea ice extent variations over the Arctic regions between the CFSR and other observations with the CFSR showing smaller sea ice extent before 1997 and larger extent starting in 1997. These deficiencies may have impacts on the application of the CFSR for climate diagnoses and predictions. Relationships between surface heat fluxes and SST tendency and between SST and precipitation are analyzed and compared with observational estimates and other reanalyses. Global mean fields of surface heat and water fluxes together with radiation fluxes at the top of the atmosphere are documented and presented over the entire globe, and for the ocean and land separately.
