Note the increase in sediments during the February time period. Images above represent weekly composites of SeaWiFS data, using the Morel K490 to chl relationship and the OC2v2 algorithm. Data represent the difference between the two algorithms. In uncontaminated, Case I waters, the algorithms perform equally well. This plume is apparent in January, maximal in February, and decreases through May in conjunction with the decrease in coastal runoff.
Blue regions are relatively uncontaminated.
