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.

  • There are number of missing data dates in this dataset. For example, most dates are missing between 2009-04-29 and 2009-12-01.
  • The estimated values for POC might be a result of the data being generated without a scale. For more information, visit the Ocean Color Forum.
