| Summary: | Marine Fish and Shellfish Survey data were collected from otter trawls in the Chukchi Sea from the OCEAN HOPE. Data were collected by the University of Alaska from 16 August 1990 to 31 July 1992. Data were processed by NODC to the NODC standard F123 Fish/Shellfish Surveys format. Full format description is available from NODC at www.nodc.noaa.gov/General/NODC-Archive/f123.html. This data type contains 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 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.
