In the surface ocean, net primary productivity (NPP) is the amount of organic carbon generated by photosynthesis in planktonic organisms minus the amount of organic carbon used by these organisms in respiration. Primary producers form the base of the food chain and generate the biomass that sustains all life in the ocean. NOAA CoastWatch provides a measurement of primary productivity based on a number of satellite measurements. These data represent seasonal 'max' values of ocean NPP generated utilizing data available from NOAA CoastWatch. Data were processed to monthly rasters, then computed into composites representing seasonal maximum values. The seasons are as follows: Winter- December, January, February; Spring- March, April, May; Summer- June, July, August. Fall- September, October, November.

Notes: NOAA CoastWatch Primary Productivity is an EXPERIMENTAL dataset, distributed for scientific evaluation NOAA CoastWatch accepts no liability for use of these data products. It is recommended that these products NOT be used for navigation. The source dataset utilized satellite measurements of photosynthetically available radiation (PAR), chlorophyll-a concentration, and sea surface temperature (SST). The method used to calculate the dataset follows the primary productivity model developed by Behrenfeld and Falkowski, 1997. This model uses these three variables to visualize the rate of primary productivity by determining how well light penetrates the water column. When there is a higher density of primary producers in the water column, the light penetration will decrease and vice versa.

The composite of vertically integrated primary productivity one day files that use the Behrenfield - Falkowski method and satellite-based measurements of Chlorophyll a, incident visible surface irradiance, and sea surface temperature. see (Behrenfield and Falkowski, L&O 1997). <br><br>
Units are in milligrams of carbon per square meter per day. <br><br>
Seasonal averages calculated from monthly averages from NOAA Coastwatch ERDDAP server at https://coastwatch.pfeg.noaa.gov/erddap/wms/erdMH1ppmday/index.html |
