The Conductivity, Temperature and Depth (CTD) and other data were collected in NE Pacific (limit-180). Data was collected from Ship POINT SUR and sent to shore via telecommunication. The data was collected over a period spanning from February 14, 1991 and November 3, 1991. Data was submitted in four files by Mr. Paul Jessen, Naval Postgraduate School, Monterey, CA. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC. F022 High-resolution CTD data is collected from high resolution (conductivity-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 1 m. 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.

The Conductivity, Temperature and Depth (CTD) and other data were collected in NE Pacific (limit-180) as part of Fieberling Seamount project. Data was collected from Ship NEW HORIZON. The data was collected over a period spanning from August 19, 1989 and September 1, 1989. Data was submitted in three diskettes by Dr. Gunnar Roden, University of Washington, Seattle, WA. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC. F022 High-resolution CTD data is collected from high resolution (conductivity-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 1 m.

Data may be reported at either equally or unequally spaced depth or pressure intervals.

Data has been processed by NODC to the NODC standard Bathythermograph (XBT) (C116) and High-Resolution CTD/STD (F022) formats. 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 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.

Conductivity, Temperature, Depth (CTD) and other data from multiple ships and other platforms were collected from NE Pacific (limit-180) from February 26, 1982 to April 5, 1983. The data was collected as part of Coastal Ocean Dynamics Experiment and submitted by Oregon State University. The bathythermograph XBT data is in C116 format of NODC while the CTD hi resolution data is in F022 format.

The Conductivity, Temperature and Depth (CTD) and other data was collected from TOGA Area - Pacific (30 N to 30 S) R/V MOANA WAVE. The data was collected over a period spanning from February 9, 1989 to May 10, 1989. Data was submitted by Harry Bryden of Woods Hole Oceanographic Institution, Woods Hole, MA. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC.

Data has been processed by NODC to the NODC standard 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 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.

The water depth and temperature data was collected in NE Pacific (limit-180) from ship SEA-LAND PACIFIC. The data was collected from September 19, 1990 to October 21, 1990. The originator's bathythermograph (XBT) data was collected as part of Shipboard Environmental data Acquisition System (SEAS) III program and was submitted in a 3.5 inch diskette by Mr. Paul Stevens of U.S. Navy, Fleet Numerical Oceanography Center, Monterey, CA. The data has been converted and is now available on line in C116 file format of NODC.
