Benthic Organisms (F132)

This file 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. A text record is available for comments.

File Structure:

Seven 80-character records: (1) Header Record, (2) Station Header Record (Tows), (3) Station Header Record (Point Sampling), (4) Environ- mental Record, (5) Bottom Characteristics Record, (6) Taxonomic Data Record, and (7) Text Record.
