Bathythermograph (XBT) data from ASIAN PROGRESS, CHEVRON MISSISSIPPI, and others in the Bering Sea, Caribbean Sea, and others from 1990-06-08 to 1991-01-14 (NCEI Accession 9100063)

Water depth and temperature data was collected from multiple ships such as MICRONESIAN INDEPENDENCE, MICRONESIAN COMMERCE, LARS MAERSK, MCKINNEY MAERSK, MOANA PACIFIC, CHEVRON MISSISSIPPI, SEA-LAND TRADER, SEA-LAND ENTERPRISE, SHIN KASHU MARU, POLYNESIA, and ASIAN PROGRESS. The data was collected from June 8, 1990 to January 14, 1991. The originator's bathythermograph (XBT) data was submitted in a diskette by Dr. Norman Hall of Scripps Institution of Oceanography (SIO), La Jolla, CA. The data containing 585 observations has been converted and is now available on line in C116 file format of NODC. 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.
