Following the Chesapeake Bay Remote Sensing Symposium in January 2006, NASA's Ocean Biology Processing Group evaluated the performance of several chlorophyll-a algorithms for the Chesapeake Bay. Details of the algorithms and their performance can be found at: http://seabass.gsfc.nasa.gov/eval/cbp_eval.cgi. As a result, the OC4v5 algorithm was recommended for experimental daily processing of SeaWiFS data at the East Coast Node. SeaWiFS Level 1A data are processed using SeaDAS 5.0 software. Mapped chlorophyll -a images are available below, however, the Level 2 data are password protected. For data access, please send requests to Paul DiGiacomo, CoastWatch Program Manager.
