Note the broad region of apparently elevated pigments in February, extending to approximately 400 km offshore, and the extremely high chl concentrations in both images.
Brighter colors represent increased sediment load.
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.
