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.

Regular server back-ups, local copies, raw data stored offsite and can be used to recreate files from backed-up programs
Level 1 ocean color data are retrieved from NASA's OceanColor Web supported by the Ocean Biology Processing Group. The NASA software SeaDAS is used to generate Level 2 and daily binned files. Statisical data and mapped netcdf files are created using code developed locally in IDL.

Daily files are used to generate weekly and monthly statistics using code developed in IDL. Monthly statistical data are used to generate annual statistics using code developed in IDL .Statistical binned data are mapped to equidistant grids for the U.S. East Coast using code developed in IDL. Netcdf files with CF compliant metadata are generated using code developed in IDL.
