The water depth and temperature data were collected in he water depth and temperature data were collected in Gulf of Mexico as part of Louisiana-Texas (LATEX part C) Gulf of Mexico Eddy Circulation Study from aircraft between May 18, 1994 and August 14, 1994. The originator's bathythermograph aerial (AXBT) data containing 108 drops were submitted by Dr. Thomas Berger, Science Applications, Inc. Raleigh NC in F022 file format of NODC. The study was supported by grant no MMS 14-35-0001-30633. LATEX is a three-part, $16.2 million federal initiative funded by the U.S. Minerals Management Service (MMS) of the Department of the Interior. The study was conducted to aid MMS in reducing risks associated with oil and gas operations on the continental shelf along the Texas and Louisiana coasts from the mouth of the Mississippi River to the Rio Grande. Begun in September 1991, it was the largest physical oceanography program ever undertaken in the Gulf. The program consists of three major parts: LATEX A, B, and C, conducted by the Texas A&M University System (TAMUS), Louisiana State University (LSU), and Science Applications International Corp. (SAIC), respectively. LATEX C was carried out by researchers at SAIC and the University of Colorado. Loop Current eddies, slope eddies, and squirts and jets within the Gulf of Mexico were located and tracked by air-deployed temperature profiling instruments and drifting buoys. Using these data, scientists assessed the impact of these Gulf-wide, circulation features on shelf circulation and identified the processes that interact with the shelf.

Data has been processed by NODC to the NODC standard Bathythermograph (XBT Aircraft) (C118) format. The C116/C118 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.

The accession contains several data sets collected during cruise P921 of the R/V Pelican as part of the Mississippi River Plume Hydrographic Study. Data submitted to NODC in delimited ASCII. One data set contains CTD (Depth, Conductivity, and Temperature data); file(s) also include salinity, dissolved oxygen, backscatter, transmissometer (turbidity), and pressure. This data does not include header information and was not able to be processed in a standard NODC format. Another data set contains Oxygen and Hypoxia data. Data was exported for NODC in delimited ASCII and is in spread sheet format. Third data set contains ADCP (Acoustic Doppler Current Profiler) data collected as part of LATEX (Louisiana-Texas) project. Data was exported for NODC in delimited ASCII. Fourth data set contains Chlorophyll (CHL), Phaeophytin, Salinity, Temperature, and Secchi Disc data. Data was exported for NODC in delimited ASCII and is in spread sheet format. Fifth data set contains Zooplankton data. All the data in this accession is considered INTERIM data; the originator's documentation and file record do not fully correlate with the actual number of files and data types submitted. Final data report was expected to be available by 08/31/93.

The originator's bathythermograph aerial (AXBT) data containing 34 drops were submitted by Dr. Thomas Berger, Science Applications, Inc. Raleigh NC.
