Oceanographic Station Data, temperature, and other data were collected using CTD and bottle casts from PARRAMATTA and other platforms in a world-wide distribution from October 4, 1903 to December 19, 1963. Data were submitted by Australia Navy as part of the California Cooperative Fisheries Investigation (CALCOFI) project. Data were processed by NODC to the NODC standard Oceanographic Station Data (SD2) and the Universal Bathythermograph Output (UBT) formats. The Oceanographic Station Data 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 are 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. Data has been processed by NODC to the NODC standard Bathythermograph (MBT) (C128) format. The C128 format is used for temperature-depth profile data obtained using the mechanical bathythermograph (MBT) instrument. The maximum depth of MBT observations is approximately 285 m. Therefore, MBT data are useful only in studying the thermal structure of the upper layers of the ocean. Cruise information, date, position, and time are reported for each observation. The data record comprises pairs of temperature-depth values. Temperature data in this file are recorded at uniform 5 m depth intervals.

Oceanographic Station Data, temperature, and other data were collected using CTD and bottle casts from CAPITAN CANEPA and other platforms in a world-wide distribution from March 21, 1921 to December 29, 1962.

Oceanographic Station Data, temperature, and other data were collected using CTD and bottle casts from A. AGASSIZ and other platforms in the Pacific ocean from July 25, 1954 to December 19, 1966. Data were submitted by Scripps Institution of Oceanography as part of the California Cooperative Fisheries Investigation (CALCOFI) project.

Temperature and salinity were collected using SDT/CDTs casts from NOAA Ship DISCOVERER and other platforms in the Coastal Waters of California from February 15, 1938 to March 27, 1985. Data were submitted by National Marine Fisheries Service - LA JOLLA as part of the California Cooperative Fisheries Investigation (CALCOFI) project. Data were processed by NODC to the NODC standard High-Resolution STD/CTD Data (F022) format. The F022 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.

CTD and bottle data were collected from AEGIR and other platforms in the North Atlantic Ocean from 10 August 1934 to 30 November 1998. CTD parameters include profiles of temperature, salinity, and sigma-t. Bottle parameters include concentrations of nitrate, total CO2, partial CO2, and silicate. Data are in the International Council for the Exploration of the Sea (ICES) ICES Oceanographic Format.

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.

Pressure, salinity, and temperature data were collected from CTD casts from the NOAA Survey Vessel BAY HYDROGRAPHER. Data were collected in the Chesapeake Bay from 05 January 2006 to 28 August 2006. Data were submitted by the National Ocean Service (NOS) and are in the old WHOI CTD Exchange Format.

Temperature, depth, and other data were collected using bathythermograph (BT/XBT) casts from NOAA Ship McARTHUR and other platforms in the Coastal Waters of California from February 19, 1985 to March 16, 1985. Data were submitted by Pacific Marine Environmental Laboratory (PMEL) as part of the California Cooperative Fisheries Investigation (CALCOFI) project. Data were processed by NODC to the NODC standard Universal Bathythermograph Output (UBT) format. The UBT 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.

Oceanographic profiles of temperature, salinity, oxygen, and other variables were acquired during numerous cruises near the Barents, Norwegian, North, and Baltic Seas from 2013 to 2016. The data were submitted to the International Council for the Exploration of the Sea (ICES) and then submitted to NCEI by ICES. The measurements were made by CTD and bottle instruments.
