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.

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.

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.

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.

This dataset is a compilation of published data on primary production, herbivory, and nutrient content of primary producers in pristine communities of microphytobenthos, macroalgae and seagrasses in estuarine systems.

Primary productivity data were collected in middle loch of Pearl Harbor, Hawaii, from 20 November 1975 to 27 November 1996. Data were collected by Leeward Community College and include results obtained employing the Winkler titration method with initial bottles, light bottles, and dark bottles. Data include rates of net productivity, gross productivity, and respiration. Time-series investigations were conducted at two hour intervals, although reduced to four sessions between 0830 to 1630 hours by inclement weather, yielded patterns resembling those observed previously in fall of 1975 and 1980 and spring of 1977. Data from all years is provided within this set.

Chlorophyll, temperature, depth, and irradiance data were collated by the Ocean Primary Productivity Working Group (OPPWG) from multiple sources in a world-wide distribution from 29 May 1958 to 02 April 1994.

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.

Technical data reports with tabulated sets of physical, biogeochemical, and fisheries data were obtained from Dr. David Ziemann of Oceanic Institute on Oahu, Hawaii. The reports are from the Association of Primary Production and Recruitment in Subarctic Ecosystems (APPRISE) project, a five-year (1985-1989) program of multidisciplinary data collection in Auke Bay, Alaska.

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.
