The Conductivity, Temperature and Depth (CTD) and other data were collected in NW Atlantic (limit-40 W) as part of Ocean Margins Program. Data was collected from Ship CAPE HATTERAS. The data was collected over a period spanning from July 14-18, 1993. Two files of CTD data was submitted by Nelson D. Sherry, Biology Department, University of Oregon, Eugene, OR via FTP.

The Ocean Station Data (OSD) and Bottle data were collected over two years period spanning from January 14, 1993 to December 20, 1994 from ships R/V CAPE HATTERAS and WEATHERBIRD II cruises #735-757. 23 OSD casts for 1993 and 26 casts for 1994 from Station-S was collected by Bermuda Biological Station for Research, Inc., Ferry Reach, Bermuda. Data was received in NODC via George Heimerdinger from Woods Hole Oceanographic Institution, Woods Hole, MA.

The Ocean Station Data; and Conductivity, Temperature and Depth (CTD) Bottle data from 25 casts were collected using ship R/V Weatherbird II during cruises # 791-813. The data was collected from January 1, 1995 to December 31, 1995 in Bremuda, NW Atlantic (limit-40 W) by Bermuda Biological Station for Research, Inc. and Woods Hole Oceanographic Institution, Woods Hole, MA. The Station S data was received by NODC via internet from George Heimerdinger.

The Conductivity, Temperature and Depth (CTD) data from HYDROSTATION 'S' were collected in NW Atlantic (limit-40 W). Data was collected from Ship WEATHERBIRD. The data was collected over a period spanning from October 26, 1988 and December 28, 1988. Data from 9 casts and 6,331 records with descriptive headers was submitted in a diskette by Dr. Rodney Johnson of Bermuda Biological Station for Research (BBSR). 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 Bottle biochemistry data from 16 casts containing Depth/ Temperature/ Salinity/ Oxygen/ phosphate/ nitrate/ nitrite/ chlorophyll/ phaeophytin/ pressure/ bacteria measurements in this accession was collected as part of Joint Global Ocean Flux Study between October 1, 1988 and September 30, 1991 using ship CAPE HATTERAS. The data was submitted by Dr. Anthony H. Knapp, Woods Hole Oceanographic Institution, Woods Hole, MA.

The Ocean Station Data from 17 stations; and Conductivity, Temperature and Depth (CTD) data from 49 casts were collected using ship Stark during cruises # 688-711. The data was collected from January 1, 1991 to December 31, 1991 in NW Atlantic (limit-40 W) by Bermuda Biological Station for Research, Inc. and Woods Hole Oceanographic Institution, Woods Hole, MA. The Station S data was received by NODC via internet from George Heimerdinger.

The Conductivity, Temperature and Depth (CTD) and Bathythermograph (XBT) data were collected as part of Texas Institutions Gulf Ecosystem Research (TIGER) project. Data was collected from Ship GYRE cruises 95G02 & 95G03 and R/V ANTARES cruise 95A03. The data was collected over a period spanning from April 1, 1995 and June 18, 1995. Data was submitted on two diskettes by Dr. Douglas C. Biggs, Texas A&M University, College Station, TX.

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.
