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: | Current direction and bathythermograph (xbt) data from moored current meter casts and other instruments in the Gulf of Mexico, Northwest Atlantic Ocean, and North American Coastline-South as part the North Carolina Frontal Eddy Dynamics Experiment (FRED) project, 23 January 1985 - 31 January 1987 (NODC Accession - 8900214) |
| Abstract: | Current direction and bathythermograph (xbt) data were collected using moored current meter casts and other instruments in the Gulf of Mexico, Northwest Atlantic Ocean, and North American Coastline-South from January 23, 1985 to January 31, 1987. Data were submitted by Science Applications, INC - Raleigh NC as part of the North Carolina Frontal Eddy Dynamics Experiment (FRED) project. Data has been been processed by NODC to the NODC standard F015- Current Meter Data and C116- Bathythermograph XBT formats. Full format descriptions are available from NODC homepage at http://www.noaa.nodc.gov.
The F015 format is used for time series measurements of ocean currents. These data are obtained from current meter moorings and represent Eulerian method of current measurement, i.e., the meters are deployed at a fixed point and measure flow past a sensor. Position, bottom depth, sensor depth, and meter characteristics are reported for each station. The data record comprises values of east-west (u) and north-south (v) current vector components at specified date and time. Current direction is defined as the direction toward which the water is flowing with positive directions east and north and negative directions west and south. Data values may be subject to averaging or filtering and are typically reported at 10-15 minute time intervals. Water temperature, pressure, and conductivity or salinity may also be reported. A text record is available for optional comments. 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: | Original Abstract: This accession contains temperature data collected during the North
Carolina Frontal Eddy Dynamics Experiment (FRED) by Evans-Hamilton Inc. in May 1987. This project was funded by MMS contracts Nos: 14-12-0001-29158 and 14-12-0001-303449. The data was submitted by Dr. Evans Waddell of Science Applications International Corp. (SAIC). Five moorings (C-1, C-3, D-3, E-2, G) were deployed in the Gulf of Mexico from January 1985 to February 1986 as part of the MMS Gulf of Mexico Physical Oceanography Program (year 4). These data were merged with the current meter data (Reference number: TV4191-3633). This data set can be found under reference numbers L00409-L00417. It should be noted that the temperature data is not an exact match to the current meter data. The data are in F015 format. Other data included are in the C116 Bathythermograph XBT format of NODC. 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.
