Current direction, marine toxic substances, and wind wave spectra data from moored current meter casts and other instruments in the Gulf of Mexico as part of the Brine Disposal project, 1977-12-22 to 1979-09-30 (NODC Accession 7900336)

Metadata Updated: February 7, 2018

Current direction, marine toxic substances, and wind wave spectra data were collected using moored current meter casts and other instruments in the Gulf of Mexico from December 22, 1977 to September 30, 1979. Data were submitted by National Data Buoy Center (NDBC) as part of the Brine Disposal project. Data has been been processed by NODC to the standard NODC F005- Current Meter Data, F144- Marine Toxic Substances, and F191- Wind Wave Spectra formats. Full format descriptions are available from NODC homepage at http://www.noaa.nodc.gov.

The F005 format is used for time series measurements of ocean currents obtained using moored current-measuring instruments, principally Aanderaa current meters (manufactured by Aanderaa Instruments Inc.). These data represent the Eulerian method of current measurement, i.e., the meters are deployed at a fixed mooring point and measure flow past the sensor. Position, water depth, and sensor depth are reported for each station. The data record comprises values of current direction and speed at specified date and time. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Other environmental parameters may also be reported. These include: water temperature, salinity, conductivity, and transmissivity; wind direction and speed; and dominant wave direction, height, and period. A text field is available for optional comments.

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.

The F191 format is used to report meteorological data and ocean wave spectra data from NDBC. The format contains seven data record types to: 1) Identify the buoy for position, duration, rate of sampling and heading. 2) Identify the meteorological parameters (temperature, pressure, weather, solar radiation, and surface waves). 3) Report time series frequency, density and resolution of waves. Each record is 120 characters in length, sorted by station and record type. The first nine columns for all records are to be used for file type (columns 1-3) and file identifier (column 4-9). The file identifier, to be assigned by the originator, is an unique originator id for each data submission. After submission, the NODC reassigns to this field an unique NODC identifier for internal use.
