This dataset contains contains chlorophyll data collected from 1958-1988 using multiple ships. Marine pigments, productivity, and associated chemistry data were collected in NE Atlantic (limit-40 W) and NW Atlantic (limit-40 W) as part of the Joint Global Ocean Flux Study (JGOFS). This data base has approx. 12,000 stations in JGOFS format. Any particulars on the station data can be found in JGR-Oceans, 97:2279-2293; titled The Remote Sensing of Ocean Primary Productivity. Data was submitted by William Balch, Rosenstiel School of Marine and Atmospheric Science (RSMAS), University of Miami. Also, these data have been copied onto CD-Rom at Goddard for distribution with the CZCS.

Depth, temperature, and other data were collected from NOAA Ship CHAPMAN, NOAA Ship DELAWARE II, NOAA Ship ALBATROSS IV, and the GLORIA MICHELE from March 30, 1991 to August 9, 1996. Data were collected by the US DOC; NOAA; NATIONAL MARINE FISHERIES SERVICE - WOODS HOLE. These data were collected using XBT casts in the Northwest Atlantic Ocean.

The data in this accession were collected in NW Atlantic (limit-40 W) from USS STOUT between October 18, 1995 and March 10, 1996. The real time data of water temperature at varying depth bathythermograph (XBT) was recorded in stripcharts by the US Navy. One line per strip chart. Some strip charts have time /date /ship id /latitude /longitude annotated on the strip chart. 85 XBT stripcharts, no log sheets were submitted to NODC.

The water temperature data was collected by International Ice Patrol from April 1986 to June 1988 in the NW Atlantic. Ships Evergreen, Hornbeam, Tamaroa and Bittersweet were used to collect the data. The C116 Bathythermograph data was submitted by the US Coast Guard, Groton, CT.

Temperature profile and water depth data were collected using BT and XBT from the OCEANUS in the Northwest Atlantic Ocean. Data were collected from 16 March 1984 to 19 March 1984 by the US Geological Survey (USGS) at Woods Hole Oceanographic Institution (WHOI). 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.

Depth, temperature, and other data were collected from the OCEANUS from June 21, 1991 to July 4, 1991. Data were submitted by Dr. Robert Weller of the Woods Hole Oceanographic Institution. These data were collected using XBT casts in the Northeast Atlantic Ocean.

The water depth and temperature data were collected in SW Atlantic (limit-20 W) as part of World Ocean Circulation Experiment cruise A23 from ship JAMES CLARK ROSS between March 23, 1995 and May 5, 1995. The originator's bathythermograph (XBT) data were submitted by Dr. Karen J. Heywood, School of Environmental Science, University of East Anglia; Norwich, UK.

Water physics and chemistry data were collected using moored current meter and bottle casts in the Northwest Atlantic Ocean from June 3, 1981 to June 9, 1981. Data were submitted by National Ocean Service (NOS) as part of the North East Monitoring Program (NEMP) project. Data were processed by NODC to the NODC standard Water Physics and Chemistry Data (F004) format. The F004 format is used for data from measurements and analyses of physical and chemical characteristics of the water column. Among chemical parameters that may be recorded are salinity, pH, and concentration of oxygen, ammonia, nitrate, phosphate, chlorophyll, and suspended solids. Physical parameters that may be recorded include temperature, density (sigma-t), transmissivity, and current velocity (east-west and north-south components). Cruise and station information, including environmental conditions of the study site at the time of observations, is also included.
