The Hi resolution conductivity, temperature and depth (CTD); Ocean Station data (OSD); Zooplankton; Bacteria; and Assorted Radiochemical data in this accession was collected as part of Bering & Pacific Russian/US Cooperative (BERPAC) Research Program between January 1 to December 31, 1993. Oceanographic Station Data contain physical and chemical oceanographic data recorded at discrete depth levels. The Oceanographic Station Data observations were made using multi-bottle Nansen casts or other types of water samplers. The data was submitted to NODC by Dr. Clifford P. Rice, United States Department of Agriculture.

The water depth and temperature data was collected from multiple ships by the Argentinian Marine Secretariat, Naval Hydrographic Service. The data was collected from 1974-1987. The originator's bathythermograph (BT and XBT) data was submitted in a tape by Dr. Adolfo J. G. Villanueva. The data has been converted and is now available on line in C116 file format of NODC.

Temperature, salinity, and other data were collected from bottle and CTD casts from the Nathaniel B. Palmer from 09 November 1994 to 08 December 1994. Data were collected from the Ross Sea in support of the Ross Sea Polynya Project. Data include profiles of temperature, potential temperature, salinity, and density anomalies. Data were collected by researchers from the Lamont-Doherty Earth Observatory of Columbia University. Project was funded by the National Science Foundation Office of Polar Programs. All data files are written in ASCII format.

Temperature, salinity, and nutrients data were collected from CTD and bottle casts in the Pacific Ocean from the Nathaniel B. Palmer from 08 October 1996 to 05 November 1996. Data were collected as part of the US JGOFS Antarctic Environments Southern Ocean Process Study (AESOPS). CTD data include temperature and salinity profiles. Bottle data include concentration profiles of nitrate, nitrite, silicate, phosphate, ammonia, phaeopigment, and chlorophyll a.

This dataset contains data from cruises that were conducted using many different ships. The bathythermograph (XBT) data was collected between January 5 and November 12, 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.
