Region(s) of distribution of Pacific Cod (Gadus macrocephalus) Tilesius, 1810 in the Arctic as digitized for U.S. Geological Survey Scientific Investigations Report 2016-5038. For details on the project and purpose, see the report at https://doi.org/10.3133/sir20165038. Complete metadata for the collection of species datasets is in the metadata document "Dataset_for_Alaska_Marine_Fish_Ecology_Catalog.xml" at https://doi.org/10.5066/F7M61HD7. Source(s) for this digitized data layer are listed in the metadata Process Steps section. Note that the original source may show an extended area; some datasets were limited to the published map boundary. Distributions of marine fishes are shown in adjacent Arctic seas where reliable data are available. The data were clipped to show only the marine distribution areas although some species also may have an inland presence.

This dataset is from a study examining the use of demersal and pelagic habitats in the southeast Bering Sea by age-0 Pacific cod, based on 4 years of demersal trawl surveys and 1 year of pelagic trawl surveys on the shelf, and 1 year of spatially intensive beam trawl sampling in a nearshore focal area along the central Alaska Peninsula.

Continue acquisition of long-term biological and physical time series. Recover and deploy moorings at FOCI site 2 and site 3. Deploy satellite-tracked drifting buoys.

To recover and deploy surface and subsurface oceanographic instrumentation moorings. To complete conductivity, temperature and depth (CTD) profiler casts. To complete bongo and CalVET tows.

We conducted an ichthyoplankton survey in the waters contiguous to Kodiak Island, Alaska. This work was needed to describe larval fish assemblages on the shelf and slope in late summer/early fall and to study the transport and early life history of larval forage fishes (ex: capelin). Zooplankton data and data on physical characteristics of the water column were also collected.

As part of the Bering Sea Integrated Ecosystem Research Program (BSIERP) funded by the North Pacific Research Board (http://www.nprb.org/bering-sea-project), cetacean surveys were conducted to describe distribution and estimate abundance on the eastern Bering Sea shelf. Three marine mammal observers conducted visual surveys along transect lines sampled during the Alaska Fisheries Science Center walleye pollock assessment survey in June and July of 2008 and 2010. We collected sighting data for all cetaceans, and produced abundance estimates for the following species: humpback whale (Megaptera novaeangliae) and fin whale (Balaenoptera physalus), minke whale (B. acutorostrata), Dalls (Phocoenoides dalli) and harbor porpoise (Phocoena phocoena).

Four time-series data sets are from instruments on biophysical moorings at the established NOAA/PMEL data-collection site "M5" on the eastern Bering Sea Shelf. Mooring were deployed at the M5 site in the Fall of each year; in September in 2015, 2016 and 2017, and October in 2018. Contract Fishing Vessel Aquila was used for deployments in 2015, 2016 and 2018 (cruises AQ1501, AQ1601 and AQ1801, respectively). NOAA Ship Oscar Dyson was used for deployments in 2017 (cruise DY1708). Moorings and instruments were left over winter and recovered the following Fall. Biophysical subsurface mooring filenames, e.g. 15bs-5a, indicate year (15) area (bs) and defined location ("5" for M5). Instrumentation included SeaBird SBE-37 (Microcat), SBE-39, SBE 56 (temperature sensor) profilers and WetLabs EcoFluorometers. Data include temperature, conductivity, salinity, pressure, water depth, raw chlorophyll fluorescence and chlorophyll a. The cruise was funded by NOAA, Pacific Marine Environmental Laboratory EcoFOCI program and NOAA Arctic Research Program with additional support from AOOS, the NOAA-regional ocean data partnership. The Ecosystem and Fisheries-Oceanography Coordinated Investigations (EcoFOCI) program is a partnership with NOAA PMEL and NOAA Alaska Fisheries Science center (AFSC). Scientists from PMEL and the University of Washington cooperative institute (CICOES) collaborated in this data collection and related data processing and analysis. Deployment and recovery operations on this cruise were managed by EcoFOCI personnel from NOAA/PMEL, NOAA/AFSC and UW/CICOES. Mooring time series data were processed at NOAA/PMEL/EcoFOCI using standard techniques. Time is recorded as UTC. Data contacts: Phyllis Stabeno, Shaun Bell, Ryan McCabe, Peggy Sullivan. Data are in NetCDF. Longitudes are in degW.

This data set describes the holding temperatures and developmental stages of larvae of red and blue king crab (Paralithodes camtschaticus and P. platypus) reared to the first crab stage at the Kodiak Laboratory.

The primary objective of this cruise was to conduct bottom trawl sampling in the head of Bering Canyon to collect ripe adult arrowtooth flounder (ATF) and conduct deep 60 cm bongo plankton tows to collect their eggs and establish their appearance so they can be identified in the future with confidence in plankton samples. The secondary objective was to collect CTD data and 20 cm bongo, chlorophyll, and nutrient samples on line "D" of the "Unimak Box".
