PHYTOPLANKTON - WET WEIGHT and Other Data from WEATHERBIRD and Other Platforms From NW Atlantic (limit-40 W) and Others from 19881020 to 19910913 (NCEI Accession 9300165)

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 NODC Accession number 9200088.) 2) Nutrient data (total carbon dioxide, nitrate+nitrite, silicate, and phosphate in umole/kg) collected as part of BATS Year 3 (Cruises 25 - 36, October 1990 - September 1991). CTD and particulate organic carbon and nitrogen (in ug/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.
