The Conductivity, Temperature and Depth (CTD); and bathythermograph (XBT) data were collected as part of Distribution/Abundance of Marine Mammals in Gulf of Mexico (GULFCET I) funded by grant no MMS 14-35-0001-30619. The data was collected over two year period spanning from April 15, 1992 to December 12, 1993. Data from 239 casts of CTD and 566 XBT drops was submitted via internet by Dr. Giulietta Fargion of Texas A&M University, Galveston, TX.

This dataset contains the final (and complete) submission of Latex-B data. Data were collected in Gulf of Mexico as part of Louisiana-Texas (LATEX part B) Gulf of Mexico Eddy Circulation Study. LATEX B was carried out by researchers at Louisiana State University (LSU). 98 files-1.929775060 gigabytes of data was submitted by Nathan Mascaro, LSU, Coastal Studies Institute, Center for Coastal, Energy & Environmental Resources. No documentation accompanies the data. 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.

The Conductivity, Temperature and Depth (CTD) and Water Depth and Temperature Bathythermograph (XBT) data were collected in Gulf of Mexico as part of Texas Institutions Gulf Ecosystem Research (TIGER) project funded by grant no MMS # 14-35-0001-30501. Data was collected from Ship GYRE cruises 92G09, 92G10 and 92G13. The data was collected over a period spanning from September 26, 1992 to October 31, 1992. Data was submitted in two diskettes by Dr. Douglas C. Biggs, Texas A&M University, College Station, TX. The originator's data containing 32 CTD observations; 52 stations and 12,860 records has been processed. CTD data is available in F022-CTD-Hi Resolution file format of NODC. The originator's bathythermograph (XBT) data has been converted and are now available on line in C116 (XBT) file format of NODC. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments. 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.

Current components, physical, and other data were collected by moored current meters and CTD casts from the J. W. POWELL and other platforms from the Gulf of Mexico from 17 March 1993 to 28 May 1993. Data were collected by Texas A&M University (TAMU) as part of the Texas-Louisiana Shelf Circulation and Transport Processes Study (LATEX PART A). Data has been processed by NODC to the standard NODC F015-Current Meter Data (Components) and the F022-CTD High Resolutions formats. This 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 F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.

The Conductivity, Temperature and Depth (CTD) and bathythermograph (XBT) data were collected in Gulf of Mexico as part of Texas Institutions Gulf Ecosystem Research (TIGER) and LATEX project funded by grant no MMS # 14-35-0001-30501.
