The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

| Title: | Chemical and bathythermograph data from moored current meter casts and other instruments in the Gulf of Mexico during the Brine Disposal project, 19 May 1981 - 12 April 1983 (NODC Accession - 8300152) |
| Abstract: | Chemical and bathythermograph data were collected using moored current meter casts and other instruments in the Gulf of Mexico from May 19, 1981 to April 12, 1983. Data were submitted by RAYTHEON CO. as part of the Brine Disposal project. Data has been been processed by NODC to the NODC standard F004- Water Physics and Chemistry and C116- Bathythermograph (XBT) formats. Full format descriptions are available from NODC homepage at http://www.noaa.nodc.gov.
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 C116 format contains temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Cruise information, position, date and time were reported for each observation. The data record was comprised of pairs of temperature-depth values. Unlike the MBT Data File, in which temperature values were recorded at uniform 5 m intervals, the XBT data files contained temperature values at non-uniform depths. These depths were recorded at the minimum number of points (''''inflection points'''') required to accurately define the temperature curve. Standard XBTs can obtain profiles to depths of either 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Prior to July 1994, XBT data were routinely processed to one of these standard types. XBT data are now processed and loaded directly in to the NODC Ocean Profile Data Base (OPDB). Historic data from these two data types were loaded into the OPDB. |

| Supplementary information: | Note: Metadata for this accession were extracted from a legacy database
maintained by the U.S. National Oceanographic Data Center (NODC). The design of the database did not exactly reflect the FGDC Content Standard for Digital Geospatial Metadata (CSDGM). Principal Investigator (PI) and organization contact information accurately represents all available information from the legacy database at the time that this description was created. However, proper attribution of a PI to a specific institution or the role (submitting or collecting) taken by an institution may not be correct due to inexact mapping between fields in the legacy database and the CSDGM. Due to this uncertainty, the contact information was initially recorded in the Supplemental Information element of the CSDGM description. To develop more accurate metadata, the NODC reviews metadata for all accessions on an ongoing basis. Points of contact for this data set include: Contact info: Agency: RAYTHEON CO.
