Plankton fluorescence and light attenuation

[ Back to article ]

Under normal summer conditions plankton are most abundant in a layer about 25 meters below the surface. Light is significantly attenuated in this layer and near the seafloor where currents resuspend sediments from the bottom. Light attenuation is lowest, making visibility greatest, beneath the layer of abundant plankton. Hurricane Edouard mixed the water column and resuspended sediment high above the seafloor. Just days after the hurricane, however, sediments settled back down.
