Benthic organisms data were collected using sediment sampler, net casts BELLOWS and other platforms in the Gulf of Mexico from 16 May 1974 to 20 February 1978. Data were collected and submitted by Dr. William Sackett of Texas University with support from the Outer Continental Shelf project. The data are from field sampling or surveys of bottom dwelling marine organisms in F132 format (described at http://www.nodc.noaa.gov/General/NODC-Archive/f132.htmland). The data provide information on species counts and species wet weight from samples collected by point sampling (grab or core) or by tow (dredge or trawl). Three operational kinds of data include: Epifauna, Infauna, and Meiofauna benthic organisms data that roughly correspond to the different sampling methods and collecting institutions that were part of this study. 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. Number of individual organisms or total weight of all organisms in the sample is reported for each taxonomic category identified by the researchers (often to Genus and Species taxonomic resolution).
