AFSC/RACE/GAP/McConnaughey: Fishpac Projects-2006-Klein 7180-EcoTriplet

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/MML: Acoustics long-term passive monitoring using moored autonomous recorders in the Bering, Chukchi, and Western Beaufort Seas, 2007-2023

The Marine Mammal Laboratory (MML) has deployed long-term passive acoustic recorders in various locations in Alaskan waters and in the High Arctic to determine spatio-temporal distribution of marine mammals as well as environmental and anthropogenic noise. Following the timing of peak calling among the various long-term recorders may provide some insight into finer-scale movements of cetaceans throughout the Bering, Chukchi, and Beaufort Seas as well as in the Gulf of Alaska. Changes in ambient noise levels can also be tracked. Recordings are available since 2007 in the Bering and Beaufort Seas, since 2010 in the Chukchi, since 2019 in the Gulf of Alaska, and from 2008-2012 in Fram Strait. The majority of these recorders were deployed on MML subsurface moorings, although several have been deployed on the oceanographic moorings of other researchers. Several different types of autonomous passive acoustic recorders have been deployed, most for one year. Recording parameters varied among instrument types and have evolved among projects. The majority of these recorders and deployments were funded by the Bureau of Ocean Energy Management (BOEM); however, funding in recent years has come from the Office of Naval Research (Marine Mammals and Biology Program), NMFS Office of Protected Resources, and the NMFS Office of Science and Technology (including the Ocean Acoustic Program).

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

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/RACE/GAP/Conrath: Delayed discard mortality of the North Pacific giant octopus

The majority of octopus bycatch occurs in Pacific cod pot fisheries and recent data collected by North Pacific Groundfish Observers indicate that immediate mortality of octopus caught in these fisheries is very small. The objectives of the proposed research were to examine the delayed mortality of E. dofleini captured in Pacific cod pot fisheries. These data are necessary to make sound management decisions for octopus based on appropriate scientific information.  This data set contains observations and measurements on the condition, weight, and survivorship of North Pacific giant octopus that were caught as bycatch in commercial fishing operations utilizing pot gear to target Pacific cod. These octopus were captured during commercial fishing operations that occurred during three fishing seasons from January 2014 through February 2015. These commercial fishing operations occurred in the central Gulf of Alaska in either Shelikof Strait or Marmot Bay. Data collected included information on octopus condition, size, sex, and injury presence. Other data collected included the location of capture, water depth, octopus air exposure time, water temperature, and gear soak time. These octopus were transported to the Kodiak sea water facility and held for a period of several months. During this period data were collected on condition, injury presence, and survivorship at 21 days. After this period octopus were held for an additional five to six weeks to assess growth within the laboratory. Octopus were fed to satiation every 72 hours during this period. Food was weighed prior to feeding and remaining food was weighed after a four hour period. The final food weight was corrected for water soaking time. Octopus were weighed once per week during this period of time. Several metrics of octopus feeding and growth were measured after this period including specific growth rate, absolute growth rate, absolute feeding rate, specific feeding rate, feeding efficiency, and daily growth rate.

AFSC/MML: Eastern Bering Sea Beluga Whale Aerial Surveys, 1992-1995, 1999-2000

In 1992-95 and 1999-2000, the U.S. Government provided funds for the Alaska Beluga Whale Committee (ABWC) to conduct studies of belugas in Alaska. Part of the ABWC research program consisted of aerial surveys of western Alaska beluga stocks, including the Eastern Bering Sea (EBS) stock. In 1992, several aerial surveys were conducted during three periods: 27-29 May, 17-21 June, and 18-22 September to assess the distribution of belugas during those periods. The surveys found relatively few belugas in May and September, but a large number of belugas in June. Based on those results, surveys in subsequent years were conducted only in June: 14-18 June 1993, 11-16 June 1994, 5-8 and 20-22 June 1995, 15-17 June 1999, and 17-20 June 2000. This dataset contains aerial survey data from the surveys described above.

AFSC/RACE/GAP/Zimmermann: Aleutians Bathymetry Grid

We assembled 2.1 million National Ocean Service (NOS) bathymetric soundings extending 1,900 km along the Aleutian Islands from Unimak Island in the east to the Russian border in the west, and ranging approximately 500 km north of the central Aleutians to Petrel and Bowers Banks, and also the surrounding deep waters of the southeastern Bering Sea. 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 also digitized 25,000 verbal surficial sediment descriptions from the smooth sheets, providing the largest single source of sediment information for the Aleutians.

AFSC/NMML: Killer whale surveys in the Aleutian Islands, Bering Sea, and western and central Gulf of Alaska, 2001 - 2010

This dataset is a compilation of line-transect data collected on surveys in the Aleutian Islands, Bering Sea, and western and central Gulf of Alaska, 2001 - 2010.  All the surveys were conducted with similar methods using line-transect protocols, allowing effort to be quantified, but there were differences in transect design in some years (some surveys were systematic, some were not).  Sighting information for all cetacean and at-sea pinniped species was collected.  The database was compiled with the intent of including all surveys with sighting data on killer whales, in order to assess killer whale population biology in this region.  Surveys included in this database are 2001 - 2007, 2009 and 2010 NMML killer whale surveys.

AFSC/NMML: Cetacean line-transect survey in the Gulf of Alaska, 2003

Three marine mammal observers participated on a cetacean survey from 26 June to 15 July 2003, aboard the NOAA ship Miller Freeman as a piggyback project during a RACE acoustic-trawl survey for pollock (see RACE.s Midwater Assessment and Conservation Engineering report here: http://www.afsc.noaa.gov/Quarterly/jas2003/divrptsRACE2.htm). A total of 2,242 km of trackline were surveyed with 364 cetacean sightings (1,079 individuals). An additional 28 cetacean sightings were made (175 individuals) during off effort periods. Species included harbor porpoise, Dalls porpoise, Pacific white-sided dolphins, killer whales, minke whales, fin whales, humpback whales, sperm whales, Baird.s beaked whales, and Cuviers beaked whales. See link for details:  http://www.afsc.noaa.gov/Quarterly/jas2003/divrptsNMML2.htm.

AFSC/RACE/GAP/Prescott: Central Gulf of Alaska Multibeam Survey H11354

We assembled 1.75 million National Ocean Service (NOS) bathymetric soundings from 225 lead-line and single-beam echosounder hydrographic surveys conducted from 1901 to 1999 in the central Gulf of 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. There were several areas where these older surveys were superseded by more recent, higher quality multibeam surveys, mostly from the NOS (n=106). Three of these were unprocessed NOS multibeam surveys in the Sitka area, which we edited and processed into final bathymetric surfaces. We reduced the resolution of these multibeam surveys to 100 m, since some may have sub-meter resolution and many exceed a million soundings, and added them to our bathymetry compilation. 
Survey H11354 was missing in the entrance to Sitka Sound. Processing and adding its bathymetric data to our compilation filled in a substantial gap in Sitka area.

AFSC/RACE/GAP/McConnaughey:Trawlex chronic effects-1997-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: South Arctic Reconnaissance-2012-Sonardyne

A custom designed Klein 7180 towed sonar was deployed from the NOAA Ship FAIRWEATHER to determine its value of acoustic backscatter as a habitat defining character. A Sonardyne Fusion USBL system was used to estimate underwater positioning of the towfish using an omnidirectional Wideband submini beacon operating in external trigger mode. Navigation data were logged in QINSy and exported into a text file. The towfish positions were then smoothed in Matlab using a custom script that implemented a weighted Hamming filter, using a window of 11 data points. These points represent the smoothed USBL navigation data for the Klein 7180 towfish during the Arctic reconnaissance transit from Dutch Harbor to Kotzebue. These smoothed towfish navigation data, however, will NOT ultimately be reinserted back into the sonar files for mosaicking and analysis. Rather, another navigation smoothing routine will be used for the final product.

We proofed, edited or digitized 96,000 cartographic features (mostly from the smooth sheets, some from the multibeam surveys), such as rocky reefs, kelp beds, rocks and islets, creating the most thorough source of these typically shallow, inshore features. The depth surface and inshore features, available at the Alaska Fisheries Science Center (AFSC: http://www.afsc.noaa.gov), were mostly produced at a map scale of 1:20,000.
