Temperature and salinity profiles were collected from CTD and XBT casts from multiple ships from 15 August 1996 to 09 April 1997. Data were collected in the Antarctic Ocean, Pacific Ocean, and other locations as part of the Master Oceanographic Observation Data Set (MOODS).

Temperature, salinity, and other data were collected from CTD casts from the Akademik Kurchatov and other platforms from 14 June 1987 to 30 October 1987. CTD data include temperature and salinity profiles. Data were submitted by the P.Shirshov Institute of Oceanology.

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.

Conductivity, Temperature and Depth (CTD) datasets were obtained from the tropical Pacific (equator, 156E) at 3 or 6 hours intervals over period spanning from November 29, 1992 to December 26, 1992. The data was collected from R/V Hakuho Maru cruise kh925 as part of the Tropical Ocean Global Atmosphere and Coupled Ocean-Atmosphere Response Experiment project. The dataset consists of temperature, salinity, dissolved oxygen and potential density data. The data are at one meter intervals between 0 m depth and 1000 m depth. The salinity data was calibrated by comparison with rosette data. 101 CTD casts data was submitted by Kensuke Takeuchi from Institute of Low Temperature Science, Hokkaido University, Sapporo, Japan.

This data set consists of Bathythermograph data extracted from a tape of physical oceanographic data submitted by the National Research Institute of Oceanography (South Africa). The data were collected on the MEIRING NAUDE from February 1968 to March 1979 (L00897), the FRAAY from June 1966 to September 1967 (L00898) and the FRANK HARVEY on january 1966 (L00899). The Nansen bottle data was processed by NODC. Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116), Bathythermograph XBT Selected Depths (SBT) (C125), and Ocean Station (C100) formats. The Oceanographic Station Data (C100) format contains physical-chemical oceanographic data recorded at discrete depth levels. Most of the observations were made using multi-bottle Nansen casts or other types of water samplers. A small amount (about 5 percent) were obtained using electronic CTD (conductivity-temperature-depth) or STD (salinity-temperature-depth) recorders. The CTD/STD data were reported to NODC at depth levels equivalent to Nansen cast data, however, and have been processed and stored the same as the Nansen data. Cruise information (e.g., ship, country, institution), position, date, and time, and reported for each station. The principal measured parameters and temperature and salinity, but dissolved oxygen, phosphate, total phosphorus, silicate, nitrate, nitrite, and pH may be reported. Meteorological conditions at the time of the cast (e.g., air temperature and pressure, wind, waves) may also be reported, as well as auxiliary data such as water color (Forel-Ule scale), water transparency (Secchi disk depth), and depth to bottom. Values of density (sigma-t) sound velocity, and dynamic depth anomaly are computed from measured parameters. Each station contains the measurements taken at the observed depth levels, but also includes data values interpolated to a set of standard depth levels. 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 UBT (C125) 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 records are comprised of pairs of temperature-depth values. Depths are selected by the originator - usually at standard horizons or some fixed interval. Standard XBTs can obtain profiles to depths of either 450 or 760 m. Special instruments permitted measurements to be obtained to 1830 m.

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 CTD from R/V SHIJIAN cruise EC-2, Nov. 18-23, 1981. These data were released by Dr. Bob Beardsley, Woods Hole Oceanographic Institution, and are the result of a joint U.S. / China research effort. Data has been processed by NODC to the NODC standard High-Resolution CTD/STD (F022) format. The F022 format contains high-resolution data collected using CTD (conductivity-temperature-depth) and STD (salinity-temperature-depth) instruments. As they are lowered and raised in the oceans, these electronic devices provide nearly continuous profiles of temperature, salinity, and other parameters. Data values may be subject to averaging or filtering or obtained by interpolation and may be reported at depth intervals as fine as 1m. Cruise and instrument information, position, date, time and sampling interval are reported for each station. Environmental data at the time of the cast (meteorological and sea surface conditions) may also be reported. The data record comprises values of temperature, salinity or conductivity, density (computed sigma-t), and possibly dissolved oxygen or transmissivity at specified depth or pressure levels. Data may be reported at either equally or unequally spaced depth or pressure intervals. A text record is available for comments.
