In the coastal ocean, distributions of colored dissolved organic matter (CDOM), dissolved (DOC) and particulate organic carbon (POC) vary seasonally and inter-annually due to multiple source inputs and removal processes. Algorithms developed to retrieve CDOM, DOC, and POC from NASA’s MODIS-Aqua and SeaWiFS satellite sensors are applied to study the processes that produce and remove organic matter in the coastal ocean. The CDOM absorption coefficient was correlated with in situ radiometry (reflectance band ratios) followed by correlation of DOC to reflectance ratios through the CDOM to DOC relationships. A POC algorithm for the northeastern U.S. continental margin was developed using in situ radiometry (reflectance band ratios) and measurements of POC. The relationships between DOC and CDOM vary seasonally and between regions requiring variable coefficients for each region (southern Middle Atlantic Bight, Hudson estuarine plume and western Gulf of Maine, USA). SeaWiFS and MODIS imagery reveal the importance of riverine/estuarine outflow from Chesapeake Bay, Delaware Bay, Hudson-Raritan Estuary, and the western Gulf of Maine to the export of CDOM and DOC to the coastal ocean and net community production of DOC on the shelf between spring and summer.
