This dataset includes fish/shellfish survey data from NOAA Ship MILLER FREEMAN in the Bering Sea from 1975-08-11 to 1975-10-26. These data were submitted by Robert J. Wolotira, NATIONAL MARINE FISHERIES SERVICE - SEATTLE. Data has been processed to the NODC standard Fish/Shellfish Surveys (F123) format. The F123 format is used for data from field sampling of marine fish and shellfish. The data derive from analysis of midwater or bottom tow catches and provide information on population density and distribution. Cruise information, position, date, time, gear type, fishing distance and duration, and number of hauls are reported for each survey. Environmental data may include meteorological conditions, surface and bottom temperature and salinity, and current direction and speed. Bottom trawl or other gear dimensions and characteristics are also reported. Catch statistics (e.g., weight, volume, number of fish per unit volume) may be reported for both total haul and for individual species. Biological characteristics of selected specimens, predator/ prey information (from stomach contents analysis), and growth data may also be included. A text record is available for comment.

Individual Animal and other data were collected using visual observation and other instruments from AIRCRAFT in the Bering Sea, Chukchi Sea, and Arctic Ocean. Data were collected from 02 September 1990 to 07 November 1991 by US DOI; Minerals Management Service in Anchorage (MMS). Data has been processed by NODC to the NODC standard Marine Mammal Sighting and Census (F127) format. The F127 format is used for data from field observations of marine animals. Data may be reported either for individual, random sightings or for sightings made as part of systematic ship or aircraft surveys along specified tracks. These data provide information on animal population densities and distributions, activities, migratory routes and breeding locales. Cruise or survey information, start and end positions, start and end times, and platform speed, direction, and altitude are reported for each observation or series of observations. Position, date and time are reported for each sighting location, along with a code indicating presence or absence of animals and, if present, their distance to the observer, shoreline, and ice edge and heading direction. For each sighting location, animal sighting data are reported by species for all observed species. Species identification, total number of individuals, and counts by age group (adults, subadults, juveniles, unknown) may be reported in summary for all animals sighted or by subgroups distinguished by sex, behavior, markings, or other characteristics. A text record is available for comments.

This data type contains data from field sampling of marine fish and shellfish. The data derive from analyses of midwater or bottom tow catches and provide information on population density and distribution. Cruise information, position, date, time, gear type, fishing distance and duration, and number of hauls are reported for each survey. Environmental data may include: meteorological conditions; surface temperature and salinity; bottom temperature and salinity; trawl depth temperature and salinity; current direction and speed. Bottom trawl or other gear dimensions and characteristics are also reported. Catch statistics (e.g., weight, volume, number of fish per unit volume) may be reported for both total haul and for individual species. Biological characteristics of selected specimens, predator/prey information (from stomach contents analysis) and growth data may also be included. Specimens are identified by an NODC Taxonomic Code. Data are very sparse prior to 1975.

This dataset contains water temperature, salinity, zooplankton, and fish survey (salmonids and other pelagic fishes) data taken by CTD, nets, and trawls from research vessel Hokko Maru in the Bering Sea. This cruise is U.S. State Department MSR U2021-002 as part of the World Data Service for Oceanography. Data are in XLSX format.

Physical, current, and other data from CTD and current meters from FIXED PLATFORMS in the Bering Sea from 25 February 1998 to 10 October 2001. Data were collected by the Pacific Marine Environmental Laboratory (PMEL) in support of the Fisheries-Oceanography Coordinated Investigations (FOCI) project. CTD parameters include temperature, conductivity, salinity, and fluorescence. Current meter parameters include East/West velocity components (U), North/South velocity component (V), current speed, current direction, turbidity, pressure, and temperature. Data are not in standard formats but are self documenting.

CTD and other data were collected from the Bering Sea from the ALPHA HELIX from 15 September 1985 to 22 September 1985. Data were collected by the University of Alaska - Fairbanks / Institute of Marine Science (UAK/IMS) as part of the Inner Shelf Transport and Recycling (ISHTAR) project. Data include temperature and salinity profiles.

Physical, current meter, biological, and optical oceanographic data were collected in the Bering Strait from August 16, 2004 to September 3, 2007. These data were collected by the University of Washington Applied Physics Laboratory personnel from moored buoys as part of the Russian-American Long-term Census of the Arctic project (RUSALCA). All data files are ASCII text with supplemental information in PDF format.

This dataset contains physical oceanography and fish abundance data collected by CTD, surface trawl, and tagged fish from the research vessel Hokko Maru in the Central Bering Sea. This dataset is U.S. State Department MSR RATS U2024-001 as part of the World Data Service for Oceanography. Data are in XLSX format, cruise report is in DOC.
