Data has been processed by NODC to the NODC standard Fish/Shell-fish 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.

This data type contains data from sampling and analysis of marine zooplankton. Information on zooplankton abundance, distribution and productivity derived from these data support studies of marine populations and ecosystems. Data reported may include: cruise information, position, date and time of sampling, bottom and sampling depths, water temperature and salinity, and total haul data. Data on zooplankton catch by species may include subsample size, zooplankton concentration, life history code and numbers of adults, juveniles, larvae, and eggs. Estimated density of holoplankton and meroplankton and data on ichthyoplankton may also be reported. Specimens are identified by NODC Taxonomic Codes.

This data type contains data from field sampling or surveys of bottom dwelling marine organisms. The data provide information on species abundance, distribution and biomass; they may have been collected by point sampling (grab or core), by tow (dredge, trawl or net), by photographic surveys, or by other methods. Cruise information such as vessel, start and end dates, investigator and institution/agency; station numbers, positions and times; and equipment and methods are reported for each survey. Environmental data reported at each sampling site may include meteorological and sea surface conditions; surface and bottom temperature, salinity and dissolved oxygen; and sediment characteristics. Number of individual organisms and total weight of organisms is reported for each species. Species are indicated by an NODC Taxonomic Code. Data are very sparse prior to 1971.

The Fish Pathology (F013) data set contains data from examinations of diseased fishes. Although these data may be from field observations, they derive primarily from laboratory analyses. Data include: location, and fishing duration, distance, and gear; catch statistics (e.g., total weight, number of individuals, age group, identity of diseases, and number of diseased individuals) by species for any number of species; and biological condition of selected specimens. The size, affected organ, location, and frequency of lesions may be reported for individual specimens. Specimens are identified with the NODC Taxonomic Code. These data may be characteristics of individual lesions or average lesion statistics.

This data type contains data from field sampling of marine organisms in intertidal or subtidal habitats. The data were collected to provide information about species abundance and distribution. Data from each observation may include: cruise and station information such as vessel name, senior scientist, position, date and time; environmental conditions such as surface temperature and salinity, wind speed and direction, and sea state; sediment and habitat descriptors; and species identification and organism counts and measurements. Data may be reported for either individual or composite samples. Specimens are identified by NODC Taxonomic Codes. A text record is available for reporting comments.

Marine Invertebrate Pathology (F063) contains data from examinations of diseased marine invertebrates. Although these data maybe from field observations, they derive primarily from laboratory analysis. Data include: catch statistics (e.g., total weight, number of individual, identity of disease and number of diseased individuals) by species for any number of species; and biological condition of selected specimens. The size location, and frequency of lesions may be reported for individual specimens. Specimens are identified by an NODC Taxonomic Code. A text record is available for comments.

The data type contains data from aircraft surveys of herring schools. These data were collected to provide information on herring population density and distribution. Start date and time, start and end positions, and aircraft type, altitude and airspeed were reported for each survey. Surveys were conducted for preassigned areas; mid-point positions of census areas were reported. Environmental information may include meteorological conditions, sea state, air roughness and water clarity. Census data include species identification, school position and activity, school size index and number of schools sighted. Predominant beach type, biota type and escarpment type may also be indicated.

This dataset contains fish/shellfish survey data collected in the Bering Sea from June 14, 1985, to August 8, 1986, by Douglas Martin, Envirosphere Co.
