AFSC/RACE/GAP/McConnaughey: Fishpac Projects-2008-Sonardyne

The broad scope of the Essential Fish Habitat (EFH) mandate requires an efficient process for describing and mapping the habitat needs of federally managed species.  For example, research indicates surficial sediments affect the distribution and abundance of many groundfish species, yet traditional sampling with grabs and cores is impractical over areas as large as the Bering Sea shelf.  Acoustic tools are suitable for large-scale surveying and show great promise as a substitute for direct-sampling methods, but they have not been proven useful for EFH purposes.

AFSC/RACE/SAP/Pathobiology: 2016 Bitter crab disease prevalence in immature Chionoecetes spp. at 6 index sites in eastern Bering Sea

This dataset contains crab data from a field survey of Chionoecetes bairdi and C. opilio collected at six designated index sites in the Bering Sea during the 2016 NOAA/NMFS/AFSC/RACE crab-groundfish bottom trawl surveys of the eastern Bering Sea. Each of the six index sites were made up of approximately 10 survey stations and chosen based on historical incidences of the parasite Hematodinium sp., the causative agent of Bitter Crab Syndrome (BCS). Blood samples were taken from collected crab using non-lethal methods and were preserved in 100% ethanol. Samples were tested in a laboratory with a DNA test to detect the presence of the parasite Hematodinium sp., the causative agent of Bitter Crab Syndrome (BCS), to evaluate any changes in intensity of disease within the index sites that may provide information as to how the disease is moving or changing within EBS crab populations. The data includes sampling year, index site, species, crab morphometrics, Hematodinium sp. parasite presence/absence based on PCR assay results.

AFSC/RACE/GAP/Prescott: Norton Sound Bathymetry

We assembled approximately 230,000 National Ocean Service (NOS) bathymetric soundings from 39 lead-line and single-beam echosounder hydrographic surveys conducted from 1896 to 2005 in Norton Sound, Alaska. These bathymetry data are available from the National Geophysical Data Center (NGDC: http://www.ngdc.noaa.gov), which archives and distributes data that were originally collected by the NOS and others. While various bathymetry data have been downloaded previously from NGDC, compiled, and used for a variety of projects, our effort differed in that we compared and corrected the digital bathymetry by studying the original analog source documents - digital versions of the original survey maps, called smooth sheets. Our editing included deleting erroneous and superseded values, digitizing missing values, and properly aligning all data sets to a common, modern datum. We incorporated 3 multibeam surveys, and added an additional 6,992 single-beam soundings from the 2010 Northern Bering Sea bottom trawl survey to fill in where smooth sheet data was lacking. We proofed and digitized 312 cartographic features, comprised mostly of rocks and islets and also digitized 4,305 verbal sediment descriptors, and digitized or adapted 2,142 km of mainland and 837 km of island shoreline.

Steller sea lion haulout and rookery locations in the United States

Steller sea lions (Eumetopias jubatus) use terrestrial sites for reproduction, resting, molting, and other activities. Sites used during the breeding season (May-August) where pupping occurs are rookeries; haulouts are sites used outside of the breeding season, and by primarily non-breeding adults and other ages throughout the year. The NOAA Alaska Fisheries Science Center National Marine Mammal Laboratory (NMML) Alaska Ecosystem Program (AEP) maintains a list of known Steller sea lion terrestrial sites in the United States portion of the sea lion range. This dataset contains site names with corresponding geographic coordinates of 472 consistently-used and known Steller sea lion haul sites. The site names are consistent throughout NMML data products and can be used to provide geospatial referencing for other NMML dataset products and publications. For legal descriptions of sites listed as Critical Habitat under the Endangered Species Act, refer to 50 CFR 226.202.

AFSC/REFM: Inshore research surveys in the eastern and central Gulf of Alaska, 2010-2013, conducted by the middle trophic level component of the GOA Integrated Ecosystem Research Project

This dataset contains the results of a series of inshore research surveys that took place during 2010-2013 as part of the Gulf of Alaska Integrated Ecosystem Research Program (GOAIERP), a multidisciplinary study of the GOA ecosystem funded by the North Pacific Research Board. The project is comprised of four groups of investigators, organized as upper, middle, and lower trophic levels plus a modeling group.  Investigators from the middle trophic level component conducted the research covered by this dataset. The study area consists of two main spatial regions (eastern: the outer coast of Southeast Alaska, western: the east side of Kodiak Island and the southern coast of the Kenai Peninsula). Within each main region the surveys covered 5-6 inshore bays or systems of bays (east: Whale Bay, St. Lazaria Island, Salisbury Sound, Islas Bay, Graves Harbor, Torch Bay; west: Kiliuda Bay, Izhut Bay, Barren Islands, Port Dick, Aialik Bay).

 At each of the inshore sites a number of research activities were conducted: 1) acoustic transects using 38- and 120-kHz split-beam transducers were conducted throughout the site to a depth of 20m; 2) sporadic nearshore acoustics were conducted from a skiff between depths of 5-20 m; 3) 10 m and 15 m beach seines were deployed along the shoreline; 4) a 50 m purse seine was deployed in depths from 3-7 m; 5) a 3-m beam trawl was deployed sporadically; 6) a 6 m X 3 m single-warp otter trawl was sporadically used for surface tows; 7) acoustic backscatter was groundtruthed using the otter trawl, jigging, and an underwater video camera;  8) oceanography stations were conducted using a Seabird 19+ CTD, a vertical zooplankton tow using a 1 m ring net, and collection of chlorophyll and nutrients samples at depths of 1 and 20 m at each station. Fish samples were taken for analyses of diet, nutritional condition, and energy content.

In 2010, pilot studies were conducted in the eastern region during July and in the western region during October. These studies did not employ all of the gears listed above, and little oceanography work was performed. In 2011, full 15-day seasonal surveys were conducted in each region (east: April, July, September; west: May, August, October). No fieldwork was conducted during 2012. In 2013 the full seasonal surveys once again took place, however due to the shutdown of the federal government the fall east survey was curtailed and the fall west survey was delayed until early November.

AFSC/RACE/GAP/McConnaughey: Trawlex BACI-2001-2002 -Klein 5410

The Resource Assessment and Conservation Engineering (RACE) Division of the Alaska Fisheries Science Center (AFSC) conducted a survey in the eastern Bering Sea (EBS) to evaluate short-term impacts of bottom trawls on soft-bottom benthic habitats and to describe the recovery process.  This was a multi-year project which follows earlier studies of long-term bottom trawling impacts in the same general region.  The study area was within the Crab and Halibut Protection Zone 1 in Bristol Bay (management area 512; approximately latitude 58 degrees north and longitude 160 degrees west.  In general, at-sea work was divided into three phases: (1) integrated biological and geological sampling before experimental trawling, (2) experimental trawling and (3) integrated biological and geological sampling after experimental trawling.  Survey activities were conducted aboard the 47.2 meter (155 ft) chartered vessel Ocean Explorer.  This was a commercial fishing vessel modified to support the research activities.  Activity during phase 1 consisted of side scan assessments of seafloor morphology with an interferometric Klein 5410 side scan sonar towfish during night wheel watches, and epifauna trawls and collection of infauna and sediment grabs during daylight hours.  All samples from a particular gear were collected in succession, so as to minimize time spent installing and configuring gear during phases (1) and (3).  Assessment activities after the impact phase were a repeat of activities prior to experimental trawling.

AFSC/RACE/GAP/McConnaughey:Trawlex chronic effects-1996-Mbt & Scanmar

The eastern Bering Sea has experienced rapid and intensive development of commercial trawl fisheries. Because of good record keeping and the relatively brief history of fishing it is possible to reconstruct the spatial and temporal patterns of exploitation. Previously unfished (UF) areas can be identified and directly compared with heavily fished (HF) areas to investigate long-term consequences for the benthos. Using this approach, macrofauna populations in a shallow (48 m average) soft-bottom area were studied during 1996. Catch data were extracted from the AFSC NORPAC database for years 1973-2001 to provide a summary of trawl catch effort, specific focus was placed on the area within Fisheries Management Area 512. The total number of hauls and tonnage for each data point are provided. Foreign, domestic, and Joint Venture fishing vessels are also described.

AFSC/RACE/GAP/McConnaughey:USBL Proof of Concept-1998-Navy Tracks

The trials were conducted in Dabob Bay, Washington, in May 1998. The main objective of these trials was to determine an accurate and reliable system to track a fishing trawl. Three USBL vendors were invited and agreed to participate in the trials. Nautronix Ltd. (Nautronix) provided their ATS II system, Simrad Subsea A/S (Simrad) provided their ITI system, and Ocean Research Equipment, Inc. (ORE) submitted their Trackpoint II Plus system. A local ORE distributor, MECCO, Inc. (MECCO), provided and operated the Trackpoint II Plus system. The U.S. Navy?s fixed, underwater tracking range in Dabob Bay, operated by the Naval Undersea Warfare Center (NUWC) Division ? Keyport, Washington, was also used in these trials. The range was used to provide simultaneous sub-sea positioning of the fishing trawl and to serve as a benchmark for system evaluations. The U.S. Navy also provided surface navigation support for the fishing vessel during these trials. The vessel selected by AFSC to conduct these trawls was the F/V Vesteraalen. It is 124 feet long, has a beam of 32 feet, and a draft of 18 feet. The F/V VESTERAALEN has a single, fixed-pitch propeller with a nozzle. By design, the vessel is like most in-shore trawlers and has, in fact, operated in Alaska in the past. The tests were conducted using NMFS otter trawls, typically used in Alaskan waters. A trial schedule was developed that would provide each vendor with three days to mobilize and test their systems. Each vendor?s equipment was attached to the fishing trawl, along with the U.S. Navy tracking gear. Both the U.S. Navy and the USBL vendor collected simultaneous trawl position data as determined by their respective equipment, with the trawl being dragged on the bottom along a predetermined track. The main objective of these trials was to assess the accuracy of each vendor?s equipment. This was accomplished using a statistical comparison between each vendor?s data and the U.S. Navy?s data that were observed simultaneously. This report details the results of these trials and summarizes the comparison results. It also contains details of the equipment and the methodologies used to collect and analyze the data. As a result of the data analysis, conclusions were drawn and recommendations have been included in this report.

AFSC/REFM: Alaska regional economic data collected through surveys 2004, 2005, 2009, Seung

Commercially available regional economic data for Alaska fisheries [such as IMpact analysis for PLANning (IMPLAN)] are unreliable.  Therefore, these data need to be either collected or estimated based on more reliable information.  These data have been collected or estimated for important economic variables such as cost, employment, and factor income (labor income and capital) for Alaska fisheries.  The data thus collected or estimated have been used to develop regional economic models for Alaska fisheries in order to estimate the economic impacts of Alaska fisheries.
