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.

Phytoplankton, chemical, nutrients, salinity, and other data from August 4, 1989 to September 7, 1989. Data were collected using bottle and CTD casts in the North Atlantic Ocean.

Physical and phytoplankton data were collected using fluorometer and CTD casts in the Northwest Atlantic Ocean from R/V OCEANUS from 18 March 2002 to 31 March 2002. Data were submitted by Dr. Robert J. Olson of Woods Hole Oceanographic Institution (WHOI) to assess the diversity and growth rates of phytoplankton in the northwest Atlantic.

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.

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.

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.

This dataset reports plankton species abundance from 5 sites off the Florida Panhandle at the head of DeSoto Canyon, Gulf of Mexico aboard the R/V Bellows cruise BE-1415 on 2014-05-31. The R/V Bellows cruise BE-1415 extended from 2014-05-29 to 2014-06-01. Quantitative phytoplankton profiles were collected at 5 sites (P1, P3, P5, P7, P9) along the Pensacola transect (Longitude -87.25 degrees N). For this, one-liter samples were collected from the surface and at different depths using Niskin bottles. Samples were filtered onto a 0.45-micrometer nitrocellulose filter and air-dried. A portion of each filter was mounted on an aluminum stub, sputter-coated, and examined with a JEOL JSM-6480 LV scanning electron microscope. Diatoms, coccolithophores, and armored dinoflagellates were identified to the lowest possible taxonomic category. The number of cells of each taxon in a field of view at a magnification of 1000x was recorded, with up to 700 fields-of-view examined, depending on the density of phytoplankton in the sample. The dataset includes the depth, the volume filtered, the number of cells of each taxon counted, and the calculated abundance of each taxon in cells per liter. Micrographs taken during the analysis are included.
