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.

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 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 Conductivity, Temperature and Depth (CTD) and other 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 #735-786. Data from 34 CTD casts for 1993 and 38 casts for 1994 from Station-S was collected by Bermuda Biological Station for Research, Inc., Ferry Reach, Bermuda. Data was received via George Heimerdinger from Woods Hole Oceanographic Institution, Woods Hole, MA.

The Nansen bottle/ primary productivity/ pigment, sediment trap; and Conductivity, Temperature and Depth (CTD) data were collected in North Atlantic Ocean, NW Atlantic (limit-40 W) as part of Joint Global Ocean Flux Study (JGOFS) project. Data was collected from Ships CAPE HATTERAS and WEATHERBIRD. The data was collected over a period spanning from October 20, 1988 and September 13, 1991. 13 files containing Sediment trap data (368 records); Primary Productivity Data (268 records); Bottle data (from 16 stations and 1,364 records); CTD data (95 stations and 52,635 records); and Pigment data (693 records) was submitted by Dr. Anthony H. Knapp, Woods Hole Oceanographic Institution, Woods Hole, MA. Data has been processed and is available in F022-CTD-Hi Resolution file format of NODC. The Joint Global Ocean Flux Study (JGOFS) is an international and multi- disciplinary study with a primary objective of understanding global oceanic carbon and nutrient cycles. The National Science Foundation has funded two time-series stations as part of JGOFS, one in Hawaii (HOTS) and a second in Bermuda, the Bermuda Atlantic Time-series study (BATS). BATS was funded under NSF Grant # OCE-8801089. This data set is comprised of BATS data primarily from Year 3, with additional data included from BATS years 1 and 2: 1) pigment data (chlorophylls a and b, peridinin, fucoxanthin, lutein, carotene, and others) collected during BATS Year 2 (These are the same data filed under NCEI Accession number 9200088.) 2) Nutrient data (total carbon dioxide, nitrate+nitrite, silicate, and phosphate in μmol/kg) collected as part of BATS Year 3 (Cruises 25 - 36, October 1990 - September 1991). CTD and particulate organic carbon and nitrogen (in μg/kg) and bacteria counts were also provided with these data. 3) Primary productivity data for BATS Years 1-3, Cruises 1-36. The trap array had MULTITRAPS at 150, 200, 300 and 400 meters. The array was allowed to drift for a 72-hour period (drift was considerable, up to 100 km). Total percentages of nitrogen, total organic carbon, and total carbon were utilized to calculate particulate flux in mg/m2/d. Data were collected in the immediate area of the nominal station location at 31 degrees 50'N, 64 degrees 10'W.

The chlorophyll data from Booth Bay Harbor in Gulf of Maine were submitted by Dr. Charles Yentsch from Bigelow Laboratory for Ocean Sciences. The data was collected aboard several vessels (Atlantis, Crawford, Bear, Chain, Knorr, Tioga, and Oceanographer) and in different sites over a period spanning from September 1956 to June 1982. Reference numbers L00843 thru L00862 represent the different cruises. Only date, latitude/longitude, depth, cruise, and chlorophyll (in mg/m3) are reported.
