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.

NODC Standard Format Primary Productivity 1 (F029) Data (1958-1983) (NCEI Accession 0014152)
공공데이터포털
This dataset contains data from measurements of primary productivity. The data are collected to provide information on nutrient levels and nutrient flow in offshore areas. In addition to cruise information, position, date, time, sampling depths, bottom depth, and environmental information, this file may contain measured parameters including: concentrations of nutrients such as phosphate, nitrate, silicate, and ammonia; temperature and salinity; and carbon assimilation. Measurements of chlorophyll a, phaeopigment, and carbon assimilation may be reported as integrated values. A free-text record is available for comments.
Primary productivity derived from ocean color remote sensing
공공데이터포털
Ocean color remote sensing provide routine, synoptic observations of the ocean surface at spatial and temporal resolutions not attainable by moored or ship-based platforms. Ocean color sensors measure the spectral distribution of reflected sunlight, which can be used to infer the contents of the water, including chlorophyll a concentrations, a proxy for phytoplankton biomass. Phytoplankton are the base of the marine food web and are critical regulators of key biogeochemical processes. Primary productivity esimates are modeled using chlorophyll a, photosynthetic available radiation, and sea surface temperature.
NODC Standard Format Primary Productivity 2 (F049) Data, 1973-1982 (NCEI Accession 0014161)
공공데이터포털
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.
Mapset: Primary productivity in northern Australian waters by northern season

Water temperature, primary productivity-phytoplankton, chlorophyll-a concentration, and other data collected by CTD, scintillation counter, fluorometer, and other instruments from Arctic Ocean from 1959-08-03 to 2011-10-21 (NCEI Accession 0161176)
공공데이터포털
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.

MODIS Derived Primary Productivity: Overall Hotspots
공공데이터포털
The dataset indicates the long-term overall primary productivity hotspots of ocean surface waters. They are derived from MODIS (aqua) images using NASA's SeaDAS image processing software. The monthly chlorophyll a images between July 2002 and August 2014 are used to identify the overall primary productivity hotspots. The extent of the dataset covers the entire Australian EEZ and surrounding waters (including the southern ocean). The value (between 0 and 1.0) of the dataset represents the likelihood of the location being a primary productivity hotspot. This research is supported by the National Environmental Science Program (NESP) Marine Biodiversity Hub through Project D1.
Phytoplankton primary productivity calculations using model and satellite data in the Nordic Seas from 2003-03-06 to 2018-10-06 (NCEI Accession 0208234)
공공데이터포털
The dataset contains daily primary production (PP) estimates in mgC/m^2/day (milligrams carbon per meter squared per day) for the subarctic Atlantic area (Nordic Seas) between 2003 and 2018, obtained with a wavelength-resolved model applied to ocean-observing satellite data (Bélanger et al., 2013; also described in the supplementary material of Mayot et al., submitted). The dataset has a spatiotemporal resolution of 8-day and ~30 km. The dataset corresponds to 16 tables (one for each year between 2003 and 2018) that contains annual time series of PP (between March 6 and October 15) for each pixel of the satellite image. The first two columns provide the longitude and latitude of each pixel were a time series of PP is available. The following twenty-seven columns correspond to estimated daily PP averaged over twenty-seven 8 days time period, from March 6 to October 7. The date in the column name is the first date of each 8 days time period.
