Chemical, benthic organisms, and other data were collected using moored current meter casts and other instruments in the Gulf of Mexico from November 11, 1983 to November 13, 1984. Data were submitted by Alaska Research Associates, Inc., as part of the Gulf of Mexico North Continental Slope Study (MNCSS) project. Data has been processed by NODC to the NODC standard F004 Water Physics and Chemistry, F123 Fish Shellfish Resource, and F132 Benthic Organisms formats. The F004 format is used for data from measurements and analyses of physical and chemical characteristics of the water column. Among chemical parameters that may be recorded are salinity, pH, and concentration of oxygen, ammonia, nitrate, phosphate, chlorophyll, and suspended solids. Physical parameters that may be recorded include temperature, density (sigma-t), transmissivity, and current velocity (east-west and north-south components). Cruise and station information, including environmental conditions of the study site at the time of observations, is also included. 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 comments. The F132 format 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.

Benthic organism were collected using sediment sampler, BT, and bottle casts from the EASTWARD and other platforms in the Georges' Bank from 10 July 1981 to 08 June 1984. Data were submitted by the Battelle Marine Research Laboratory in New England with support from Ocean Continental Shelf - Georges' Bank project. The F132 format 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.

Benthic organisms data were collected using sediment sampler and 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. 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).

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.

Measurements of hydrocarbons in sediments and tissues, trace metals in tissues of benthic fauna, as part of the Georges Bank Monitoring Program (Year 1) funded by the Minerals Management Service of the Dept. of the Interior. Data has been processed by NODC to the NODC standard Marine Toxic Substances and Pollutants (F144) format. The F144 format contains data on ambient concentrations of toxic substances and other pollutants in the marine environment. The data derive from laboratory analyses of samples of water, sediment, or marine organisms. Samples may have been collected near marine discharge sites or during ocean monitoring surveys of large areas. Field observations of tar deposits on beaches may also be reported. Survey information includes platform type, start and end dates, and investigator and institution. If data are collected near a discharge site, discharge location, depth, distance to shore, average volume, and other characteristics are reported. Position, date, time and environmental conditions are reported for each sample station. Environmental data may include meteorological and sea surface conditions, tide stage and height, depth of the thermocline or mixed layer surface temperature and salinity, and wave height and periods. Sample characteristics, collection methods, and laboratory techniques are reported for each sample collected and analyzed. The data record comprises concentration values (or a code to indicate trace amounts) for each chemical substance analyzed. Chemical substances are identified by codes based on the registry numbers assigned by the Chemical Abstracts Service (CAS) of the American Chemical Society. Marine organisms from which samples have been taken are identified using the 12-digit NODC Taxonomic Code. A text record is available for optional comments.

These data were collected to evaluate the best measures of the effect of contaminants on the biota to be used as part of the National Status and Trends Program. Sediment and benthic samples were collected in coastal waters around San Francisco Bay, specifically from the Russian River to Santa Cruz. The samples were collected from November 1, 1986 to February 27, 1987. Each sample was tested for trace metal and organic compound concentrations, organic carbon and texture. The originator's data are in Microsoft Excel spreadsheet submitted by Dr. Edward Long from NOS/CEAB. They are documented in the NOAA technical memorandum nos OMA 45 (1989) titled "An Evaluation of Candidate Measures of Biological Effects for the National Status and Trends Program".
