Current direction, chemical, benthic organisms, and other data from moored current meter casts and other instruments in the Gulf of Mexico during the Brine Disposal project, 1981-01-21 to 1982-07-27 (NODC Accession 8200207)

current direction chemical benthic organisms and other data were collected using moored current meter casts and other instruments in the gulf of mexico from january 21 1981 to july 27 1982 data were submitted by texas a m university as part of the brine disposal project data has been been processed by nodc to the nodc standard f005 current meter data f004 water physics and chemistry and f132 benthic organisms formats full format and format code descriptions are available at http www nodc noaa gov general nodc datafmts html 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 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 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
