Description:
Chlorophyll-A concentration describes the concentration of chlorophyll-a at the ocean surface in units of mg / m3 for Spring, Summer, Fall, and Winter.

Chlorophyll-A concentration can be an indicator of ocean productivity as Chlorophyll-A is the main pigment used by phytoplankton to capture light energy and convert that energy into biomass. Because Chlorophyll-A is unique to plants and easy to quantify, it is a convenient biomass proxy for phytoplankton. Therefore, Chlorophyll-A concentration is one of the most frequently measured variables in plankton ecology and environmental monitoring programs. Numerous ecosystem analyses, including food web calculations and time series of ecosystem responses, are based on Chlorophyll-A concentrations

These data were derived from the NASA OceanColor Aqua and Terra MODIS and VIIRS (1997-2017) data products.
