AFSC/REFM: Digitized 2005 GOA Trawl Logbooks merged with Fish Ticket and Observer data

The data include a full year of logbook forms for vessels 60-124 feet in length (the partial coverage fleet) that had participated in the trawl flatfish fishery of 2005 in the Gulf of Alaska. The digitized hauls were not restricted exclusively to the population of trips to the Gulf of Alaska (GOA), since some vessels also participated in BSAI trawl fisheries. A total of 55 unique vessels daily fishing logbooks (9 catcher-processors and 46 catcher vessels) were digitized into the Vessel Log System database. The daily production section for catcher-processors was not digitized, therefore they were excluded from the data entry procedure and we focus on the remaining catcher vessels. These logbook records are then combined with observer and fish ticket data for the same vessels to create a more complete accounting of each vessels activity in 2005.  In order to examine the utility, uniqueness, and the congruence of data contained in the logbooks with other sources, we collated vessel records from logbook data with Alaska Commercial Fisheries Entry Commission (CFEC) fish tickets (retrieved from the Alaska Fisheries Information Network (AKFIN)) and the North Pacific Groundfish Observer Program  observer records. Merging of datasets was a multiple-step process. The first merge of data was between the quality-controlled observer and fish ticket data. Prior to 2007, the observer program did not track trip-level information such as the date of departure and return to/from port, or landing date. Consequently, to combine the 2005 haul-level observer data with the trip-level data from the fish tickets for a given vessel, each observer haul was merged with a fish ticket record if the haul retrieval date from the observer data was contained within in the modified start and end date derived from the fish ticket data (see above). Since the starting date on the fish ticket record represents the date fishing began, rather than the date a vessel left port, all observer haul records should be within the time frame of the fish ticket start and end dates. The observer hauls were therefore given the same trip number as determined by the fish tickets trip numbering algorithm. The same process was then repeated to merge each logbook haul onto the combined fish ticket and observer data. Trip targets were then assigned from the North Pacific Fishery Management Council comprehensive observer database (Council.Comprehensive_obs) for observed trips, and statistical areas denoted on the fish tickets were mapped to Fishery Management Plan (FMP) areas. After quality control, the dataset was considered complete, and is referred to as the combined dataset.

AFSC/RACE/GAP/Rooper: Response of fish to drop camera systems

Assessing rockfish abundance in untrawlable habitats is a key area of study for the Alaska Fisheries Science Center. In order to accurately estimate abundance knowledge of rockfish response to the observation platform must be known. In 2013, we performed a series of experiments to examine rockfish response to a stereo drop camera. These data area stored as image files, .Rdata files, .sql3 files and as .xlsx files.

AFSC/RACE/GAP/McConnaughey: Trawlex BACI-2001-2002 -Grabs

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.

Photogrammetry Measurements of Seals from UAS Imagery

We used an uncrewed aerial system (UAS) to collect imagery of bearded, ringed, and spotted seals at captive care facilities, and used photogrammetry of the UAS images to develop a model to estimate body mass to use as an indicator of body condition. We collected measurements from the UAS images, which were taken with the UAS directly over the seals with the camera at nadir. We also tested the UAS's ability to successfully collect imagery of ice seals in the Bering Sea during two research cruises. We demonstrated that a UAS can operate and collect images of ice-associated seals in arctic conditions, and that photogrammetry of the imagery can be used to estimate body mass, potentially increasing the number of seals of these populations that can be assessed for body condition.

Satellite Telemetry Dataset (Raw): Juvenile Bearded and Spotted Seals, 2004-2006, Kotzebue, Alaska

Bearded seals (Erignathus barbatus) are one of the most important subsistence resources for the indigenous people of coastal northern and western Alaska, as well as key components of Arctic marine ecosystems, yet relatively little about their abundance, seasonal distribution, migrations, or foraging behaviors has been documented scientifically. Ice-associated seal populations may be negatively impacted by offshore oil and gas development as well as by climate change. During a cooperative effort between scientists and subsistence hunters in October 2004, 2005, and 2006, 13 female and 13 male juvenile (i.e., age <2) bearded seals (Erignathus barbatus) were tagged with satellite-linked dive recorders (SDRs) in Kotzebue Sound, Alaska. While the focus of this study was on young bearded seals, an additional three female spotted seal (Phoca largha) pups and two adult spotted seal males were captured and deployed with satellite telemetry devices.

The data files within this dataset represent the 'raw' data obtained from the Wildlife Computers data portal. Each deployment (unique tag id + animal id combination) is provided as a zipped archive. The root folder also includes additional documentation. The various files and detailed column descriptions are described in the 'Spreadsheet-File-Descriptions.pdf' which was downloaded from Wildlife Computers (https://wildlifecomputers.com/support/downloads/). The '00_kotzeb04_get_data.Rmd' file is an RMarkdown file that provides code and documentation of the data retrieval process. The corresponding '00_kotzeb04_get_data.hml' file is generated from the RMarkdown file.

AFSC/REFM: Movement of Alaska skates (Bathyraja parmifera) in the Bering Sea , determined through conventional tagging

This dataset contains the results of a tagging study being conducted on the Alaska skate (Bathyraja parmifera) in the eastern Bering Sea. The purpose of the study is to gain a basic understanding of the timing and spatial pattern of movements of Alaska skates in the Bering Sea. The tags used are conventional (i.e. non-electronic) tags that are generally recovered through commercial fishery catches of skates. Skates were tagged aboard the AFSC eastern Bering Sea shelf surveys in 2008, 2009, and 2010. Skates greater than 60 cm total length received a Floy dart tag; skates smaller than 60 cm total length received a Floy T-bar tag. A reward system was implemented to encourage recovery of tags, but as there are no directed fisheries for skates the number of tags recovered is expected to be relatively low. As of December 2015, 41 tags have been recovered out of approximately 3,000 tagged skates. This dataset will be updated on a regular basis as more tags are recovered.

AFSC/RACE/GAP/Prescott: Norton Sound Features

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.

AFSC/NMML/CCEP: Diet of Pacific harbor seals at Umpqua River, Oregon and Columbia River, Oregon/Washington during 1994 through 2005

From 1994 to 2005, The National Marine Mammal Laboratories' California Current Ecosystem Program (AFSC/NOAA) collected fecal samples at the Umpqua River, Oregon and Columbia River, Oregon/Washington to examine the diet of Pacific harbor seals (Phoca vitulina). Scats were collected at various sites on the Umpqua River and at Desdemona sand spit on the Columbia River. Apart from describing the diet of Pacific harbor seals in these regions, of special interest was to determine the level of predation by these seals on endangered or threatened salmonids (e.g. cutthroat trout; Oncorhyncus clarkii).

AFSC/ABL: Little Port Walter Marine Research Station Supply Run Oceanographic Observations

In November, 2006, Oceanographic observations were initiated during the resupply cruises to the Little Port Walter Research Station on lower Baranof Island, Southeast Alaska. Six sampling stations were selected starting at mid channel, Stephans Passage near Snettisham Inlet then, near the intersection of Stephans Passage and Fredrick Sound by Brothers Islands, then, near the intersection of Fredrick Sound and Chatham Strait off of Kingsmill Point and then three stations across lower Chatham Strait just north of the latitude of Little Port Walter. An SBE19plus conductivity, temperature and depth recorder was used to take water samples at a speed of approximately one meter per second from the surface to a depth of 250 meters. These observations are intended to be part of the Southeast Alaska Ocean Observing System (SEAOOS). Data are stored as CNV files, HEX files and jpg files on Frank Throwers computer.

AFSC/RACE/GAP/McConnaughey: Trawlex Chronic Effects: UAF Infauna

Benthic communities are structured by dynamically interacting factors that determine habitat quality. Since benthic macrofauna demonstrate strong and often narrowly defined affinities, forces altering (or disturbing) the environment will be of considerable importance to their distribution and abundance. Commercial fishing with mobile gear, such as bottom trawls and dredges, and the physical disturbance that results, is widespread in continental shelf areas. Because of its prevalence and the potential for adverse effects, there have been numerous attempts to quantify sea-floor exposure at various spatial scales. The well documented development of commerical fisheries in the eastern Bering Sea (EBS) since 1954 presents a unique opportunity for studying trawling impacts. The Crab and Halibut Protection Zone 1 (CHPZ1; also known as management area 512), located north of the Alaska Peninsula in Bristol Bay, has a long and complex history of trawl prohibitions that extend from 1959 to the present. Using detailed accounts of closures and fishing activity, it is possible to reconstruct historical effort and identify essentially pristine areas immediately adjacent to areas that have been heavily fished with bottom trawls. This physical arrangement permits an examination of chronic disturbance by bottom trawls, without confounding environmental effects that result from geographic separation. Sampling locations were preselected on the basis of historical fish effort. Starting positions for commercial bottom trawls (n=392 743 through July 1996) were spatially joined with a 1 nm2 grid to calculate total number of trawls per nm2, and thus identify heavily fished (HF) and unfished (UF) areas along the boundary of the CHPZ1 (NORPAC fishery observer database maintained at the NMFS Alaska Fisheries ScienceCenter, Seattle, Washington). HF and UF cells on opposite sides of the boundary line were paired a priori on the basis of spatial proximity and were generally separated by 1 nm to allow for prior navigational discrepancies. A total of 42 pairs was identified at the northeastern corner of the CHPZ1. In 1997, 54 grab samples were obtained using a 0.05 m^2 Sutar van Veen (SvV) sampler deployed from the FV Golden Dawn at many, but not all, of the paired sites in the sandy, high-current northeast corner of management area 512. An additional 28 grabs were acquired in the central region of management area 512 as part of a completely different BACI project while sampling protocols were being ironed out in the early stages of the effort. This point file contains the weights (g) of various infauna obtained from 83 grab samples.

AFSC/RACE/GAP/Nichol: Archival tag depth and temperature data from northern rock sole

Depth data from archival tags on northern rock sole (Lepidopsetta polyxystra) were examined to assess whether fish used tidal currents to aid horizontal migration. Two northern rock sole, out of 115 released with archival tags in the eastern Bering Sea, were recovered 314 and 667 days after release. Both fish made periodic excursions away from the bottom during mostly nighttime hours, but also during particular phases of the tide cycle. One fish that was captured and released in an area of rotary cur rents made vertical excursions that were correlated with tidal current direction. To test the hypothesis that the fish made vertical excursions to use tidal currents to aid migration, a hypothetical migratory path was calculated using a tide model to predict the current direction and speed during periods when the fish was off the bottom. This migration included limited movements from July through December, followed by a 200-km southern migration from January through February, then a return northward in March and April. The successful application of tidal current information to predict a horizontal migratory path not only provides evidence of selective tidal stream transport but indicates that vertical excursions were conducted primarily to assist horizontal migration.

AFSC/NMML: Small cetacean aerial survey in Alaskan waters, 1997-1999

Aerial surveys were conducted to produce abundance estimates for the three Alaska stocks of harbor porpoise. Surveys occurred from May to July 1997 for the Southeast Alaska stock, May to July 1998 for the Gulf of Alaska stock, and June to July 1999 for the Bering Sea stock. Two primary observers observed from bubble windows on the left and right side of the plane. A belly window observer with a view directly down along the trackline collected sightings that were matched to the side observers and used to estimate a correction factor for perception bias that was specific to harbor porpoise in Alaskan waters.
