This data file consists of chlorophyll and other parameter built from existing NODC files F004, water physics/ chemistry, F029, primary productivity, as well as other sources. This data file is used for the in situ data of the CZCS (Coastal Zone Color Scanner) browse system. The data were collected from November 1978 to May 1980 in the Northwest Pacific, Northwest Atlantic and the Gulf of Mexico. The data were assembled by Dr. Elaine Collins and Peter Pytlowany.

The accession contains chlorophyll-A and phaeophytin data collected by Florida State University in the North American coastline for three time periods in 1986. First data set was collected in February, second was collected in April and the last data set was collected in September of the same year. The principal investigator in this study was Dr. Richard Iverson. The data are in Lotus 1-2-3 format. Approximate study location was Atlantic coast; 26-39 degrees N and 71-80 degrees W. Parameters include: position, chlorophyll A (in milligrams per cubic meter) and phaeophytin (in milligrams per cubic meter). Samples were taken every two hours. Additional data associated with this study is filed under NODC reference numbers L00358-L00360.

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.

Temperature profile and phytoplankton data were collected using XBT and CTD casts in the Northwest Atlantic Ocean from R/V ENDEAVOR from 01 October 2001 to 15 October 2001. Data were submitted by Dr. Robert J. Olson of Woods Hole Oceanographic Institution (WHOI) with support from the Active fluorescence assays of phytoplankton physiological state: Population and individual cell measurements project.

A set of phytoplankton pigment measurements collected on eight quarterly transects from France to New Caledonia is analyzed in order to identify the main assemblages of phytoplankton and to relate their occurrence to oceanic conditions.
