Item Identification
| Title: | Chlorophyll a time series |
|---|---|
| Short Name: | Chlorophyll |
| Status: | Completed |
| Abstract: |
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. |
