The data in this accession were collected in 26 cruises conducted using multiple ships over a decade between August 1980 to July 1991. The real time data of water temperature at varying depth bathythermograph (XBT) was recorded in stripcharts by the US Navy. One box of analog stripcharts and radio logs were submitted to NODC by Mr. Paul Stevens of Fleet Numerical Oceanography Center, Monterey CA. The XBT data from these stripcharts have been digitized and are present in the current NODC data storage system in C116 file format.

The bathythermograph data in this accession were collected using six different ships between November 2, 1990 and December 2, 1991. The real time data of water temperature at varying depth bathythermograph (XBT) was recorded by the US Navy. The data was submitted to NODC by Fleet Numerical Oceanography Center, Monterey CA. The XBT data has been digitized and is present in the current NODC data storage system in C116 file format.

The data in this accession was collected from US Coast Guard Cutter Sherman between February 16, 1990 and March 2, 1990. The real time data of water temperature at varying depth bathythermograph (XBT) was recorded in stripcharts by the US Navy. These eleven stripcharts and radio logs were submitted to NODC. The XBT data from these stripcharts have been digitized and is present in the current NODC data storage system in C116 file format.

The data in this accession were collected from ship HAMILTON between June 27, 1991 to July 25, 1991. The real time data of water temperature at varying depth bathythermograph (XBT) was recorded in stripcharts by the US Coast Guard. Sixty three stripcharts and radio logs were submitted to NODC. The XBT data from these stripcharts have been digitized and are present in the current NODC data storage system in C116 file format.

The data in this accession were collected from ship HAMILTON between August 25, 1990 to October 21, 1990. The real time data of water temperature at varying depth bathythermograph (XBT) was recorded in stripcharts by the US Coast Guard. Fifty four stripcharts and radio logs were submitted to NODC. The XBT data from these stripcharts have been digitized and are present in the current NODC data storage system in C116 file format.

The data in this accession was collected during 46 cruises from 26 different ships over a period of 14 years spanning from November, 1976 and September, 1990. The real time data of water temperature at varying depth bathythermograph (XBT) was recorded in stripcharts by the Fleet Numerical Oceanography Center, Monterey, CA. One box of these stripcharts and radio logs were submitted to NODC by Mr. Paul Stevens. The XBT data from these stripcharts have been digitized and is present in the current NODC data storage system in C116 file format.

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 from multiple ships by the Australian Navy. The data was collected from 1978-1991. The originator's analog bathythermograph (XBT) data was submitted in a box along with eight cassette tapes by Mr. Ben J. Searle. The data has been converted and is now available on line in C116 file format of NODC.
