Description

This level 3 product includes ocean color and satellite ocean biology data produced or collected under EOSDIS.

This dataset may be used for studying the biology and hydrology of coastal zones, changes in the diversity and geographical distribution of coastal marine habitats, biogeochemical fluxes and their influence in Earth's oceans and climate over time, and finally the impact of climate and environmental variability and change on ocean ecosystems and the biodiversity they support.

Scale factor and offset are already applied.

Documentation:

Newer datasets have scaled POC values while older ones don't. This scaling gets rid of negative values but older datasets still retain them hence the -2147.48 estimated minimum value. For more information, visit the Ocean Color Forum.
