Arctic Ocean net primary productivity (NPP) was assembled for 1959-2011 from existing databases and recent polar research cruises. At each NPP station, if available, other data such as Chl-a, nitrate, and nitrite concentrations, mixed layer depth (MLD), SST, and euphotic layer depth were included. The data were obtained between 65 and 89°N mainly from late spring to early fall. At each station, NPP was measured at various depths using 13C- or 14C-labeled compounds. Surface fluorometric Chl-a concentration and SST were estimated from measurements between 0 and 5 m depth. MLD was estimated from CTD profiles using 0a threshold criterion. Nitrate and nitrite concentrations were measured only in the upper 100 m. Sponsored by the NASA through the Primary Productivity Algorithm Round Robin activity (PPARR) program. Data were provided in xlsx format and converted by NCEI to csv format.

Arctic Ocean primary production data were assembled from original input data archived in various international databases, provided by individual investigators or in publications. The data were collected by various methods and resulted from the efforts of many individual, national and international research efforts conducted between 1954 and 2007. Station data (cruise, station, latitude, longitude, depth), discrete data for productivity and chlorophyll a (value, method, phase, incubation type and length), photosynthetically available radiation (PAR) (incoming, integrated over incubation period), some integrated parameters, and some hydrographic parameters (nutrient concentration, mixed layer depth) as well as source (investigator, data base, publication, etc.), if available, were included.

This dataset contains data from measurements of photosynthetic capacity and phytoplankton productivity. In addition to cruise information, position, date, time, sampling depths, bottom depth, and general environmental information, this dataset may contain measured parameters including: concentrations of chlorophylls a, b, c, plant carotenoids, and phaeopigments; concentrations of oxygen, particulate organic carbon, ammonia, nitrite, nitrate, silicate, and urea; temperature, salinity, and total alkalinity; and light penetration and light intensity. Values of photosynthetic capacity and primary productivity may be reported as total values or partial values for phytoplankton, net plankton, nanoplankton, and dissolved organic matter.

These data include monthly composite satellite images obtained by the research programme.

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 dataset consists of monthly net primary productivity (NPP) estimates for 1998-2009 derived from the Vertically Generalized Production Model (VGPM) for the 26 Outer Continental Shelf planning areas in the United States, produced by CSA International, Inc. (CSA) under contract to the U.S. Department of the Interior, Bureau of Ocean Energy Management, Regulation and Enforcement. The NPP data are provided as GeoTIFF files depicting global gridded monthly NPP estimates. Summary NPP statistics for each of the 26 planning areas are also provided as separate ASCII text files. Input datasets used in the VGPM were also provided by CSA and present in this accession. These input datasets include global monthly sea surface temperature from the AVHRR Pathfinder Version 5.0 data set, global photosynthetically available radiation (par) and chlorophyll-a concentration data from the SeaWiFS and MODIS instruments, and global climatological monthly mean photoperiod data. These input datasets are provided in HDF4, with the exception of the photoperiod data which is provided in binary format.

This dataset is derived from NOAA Coral Reef Watch CoralTemp sea surface temperature and chlorophyll-a concentration from the European Space Agency Ocean Colour Climate Change Initiative dataset using algorithm from Barns et al., (2011). This is a monthly data with a spatial resolution of 0.05 degree. The spatial coverage is 20S to 55N, 120E to 100W, from 1998-01 to 2024-12. Reference: Barnes, C., Irigoien, X., De Oliveira, J.

Net primary productivity determined from 13C-labeled in situ incubations. Water collected via Niskin bottle was incubated with labeled bicarbonate for 24 hours at the original collection depth, and 13C-incorporation into suspended particulate organic carbon determined via mass spectrometry. Measurements made in the Gulf of California in the summers of 2004, 2005, and 2008, as well as from the Eastern Tropical North Pacific in 2008.

Zooplankton biomass data were collected from net tows from the South Pacific Ocean. Data were collected by the Bedford Institute of Oceanography (BIO) from 27 January 1967 to 26 November 1967. Zooplankton samples were obtained from oblique tows and parameters include maximum tow depth, total water volume passed through net, small plankton volume, total plankton volume, and standard haul factor.

Phytoplankton data were collected using net casts from the USCGC POLAR SEA in the Arctic Ocean. Data were collected from 26 July 1994 to 26 August 1994. Data were submitted by Oregon State University (OSU) with support from the Arctic Ocean Section (Canada/U.S. joint expedition) project.
