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.

This dataset contain data from Nine Seas III cruises conducted using many different ships. The bathythermograph (XBT) data was collected between March 28 and August 31, 1989. The data were sent from the cruise ships to the National Ocean Service, Rockville, MD via telecommunication. This data was submitted by Mr. Woodward E. William and is currently available in the C116 file format of NODC.

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.

This dataset contains datasets collected over a period of one year. The cruises were conducted using many different ships as part of Shipboard Environmental data Acquisition System (SEAS) III program. The bathythermograph (XBT) data was collected between April 4, 1990 and April 16, 1991. The data were sent from the cruise ships to the National Ocean Service, Rockville, MD via telecommunication. This data containing 934 observations is currently available in the C116 file format of NODC.

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.

This dataset contains 14 sets of data collected as part of Shipboard Environmental data Acquisition System (SEAS) III program. The cruises were conducted using 10 different ships. The bathythermograph (XBT) data was collected between September 1, 1987 and April 10, 1992. The data was sent from the cruise ships to the National Ocean Service, Rockville, MD via telecommunication. This data is currently available in the C116 file format of NODC.

The water temperature and depth data in this accession was collected by Hydro Department of Birkenhead, Merseyside, UK. Three different ships were used to collect the 371 bathythermograph (XBT) observations spanning from May 19, 1983 to May 31, 1988. The data was submitted by Mr. P.F. Wainwright. The data has been processed by NODC and is available in C116 Bathythermograph (XBT) file format.
