Temperature profile and water depth data collected from OCEANUS in the NW Atlantic (limit-40 W) from 1984-03-16 to 1984-03-19 (NCEI Accession 8700162)

Temperature profile and water depth data were collected using BT and XBT from the OCEANUS in the Northwest Atlantic Ocean. Data were collected from 16 March 1984 to 19 March 1984 by the US Geological Survey (USGS) at Woods Hole Oceanographic Institution (WHOI). 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.
