Mississippi Bight, Northern Gulf of Mexico (image) Dauphin Island Sea Lab Share Print E-Mail Caption Mississippi Bight region with the CONCORDE 2016 summer survey transects (labelled thick red lines) with the associated dissolved oxygen (DO) conditions. Coloration is 7-d average of chlorophyll-a derived from MODIS sensor (1 km resolution) for the week of July 20-26, 2016. Due to the optical complexity of coastal waters, the chlorophyll-a concentration represents relative values but effectively illustrates an intrusion of fresher water (yellow filament) on the shelf in contrast to clear Gulf of Mexico water (blue).
