Conductivity, Temperature and Depth (CTD) and bathythermograph (XBT) data were collected in the Gulf of Mexico as part of Texas Institutions Gulf Ecosystem Research (TIGER) project funded by grant No. MMS 14-35-0001-30501. Data were collected from Ship GYRE cruises 94G02, 94G03 and 94G05. The data were collected from May 11, 1994 to July 20, 1994. Data from 11 CTD stations and 29 XBT drops were submitted on three diskettes by Dr. Douglas C. Biggs, Texas A&M University, College Station, TX.

Temperature profile and water depth data were collected using BT and XBT casts from the USCGC FORWARD in the Gulf of Mexico. Data were collected from 11 March 1992 to 01 April 1992 by the US Coast Guard. Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) 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 water depth and temperature data was collected in Gulf of Mexico from ships GYRE and J. W. POWELL as part of Ship Of Opportunity Programme (SOOP) and Texas Institutions Gulf Ecosystem Research Program. The data was collected from October 9, 1994 to December 6, 1994. The originator's bathythermograph (XBT) data was submitted on two diskettes by Dr. Edward Webb of Texas A&M University, College Station, TX.

Temperature profile and water depth data were collected using BT and XBT casts from the EDGAR M. QUEENY in the Gulf of Mexico. Data were collected from 13 December 1985 to 22 December 1985 by National Marine Fisheries Service in Narragansett Bay Laboratory (NMFS) with support from the Ships Of Opportunity Program (SOOP). Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) format.

Temperature profile data were collected using XBT and BT casts from NOAA Ship RESEARCHER and other platforms in the Gulf of Mexico and other locations from 11 November 1983 to 20 January 1985. Data were collected by the Pacific Marine Environmental Laboratory (PMEL). Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. The UBT file format is used for temperature-depth profile data obtained using expendable bathythermograph (XBT) instruments. Standard XBTs can obtain profiles at depths of about 450 or 760 m. With special instruments, measurements can be obtained to 1830 m. Cruise information, position, date, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Unlike the MBT data file, in which temperature values are recorded at uniform 5m intervals, the XBT Data File contains temperature values at non-uniform depths. These depths are at a minimum number of points ("inflection points") required to record the temperature curve to an acceptable degree of accuracy. On output, however, the user may request temperature values either at inflection points or interpolated to uniform depth increments.

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) project funded by grant no MMS # 14-35-0001-30501. Data was collected from Ship GYRE cruise 92G08. The data was collected over a period spanning from October 19, 1994 and October 25, 1994. Data from 15 XBT drops and 54 CTD drops was submitted in one diskette by Dr. Edward Webb of Texas A&M University, College Station, TX.

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) project. Data was collected from Ship GYRE. The data was collected over a one year period spanning from January 1, 1993 to December 31, 1993. Data was submitted in one diskette by Dr. Edward Webb, Texas A&M University, College Station, TX.

Data was collected from Ship GYRE cruise 94G05. The data was collected over a period spanning from July 18, 1994 and July 20, 1994. Data was submitted in two diskettes by Dr. Douglas C. Biggs, Texas A&M University, College Station, TX via Eddie Webb. Data from 9 CTD stations containing 18,570 records has been processed and is available in F022-CTD-Hi Resolution file format of NODC. F022 High-resolution CTD data is collected from high resolution (conductivity-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 1 m. 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.
