Ocean color satellite imagery has been used to detect blooms of phytoplankton for decades. A bloom in this sense is defined as a rapid increase in chlorophyll-a concentration from newly synthesized sources (primary production) within the photic zone. Chlorophyll also has the potential to enter the water column from benthic sources as a result of resuspension events. Currently available bio-optical...
Blooms of the toxic dinoflagellate, Karenia brevis, have had detrimental impacts on the coastal Gulf of Mexico for decades. Detection of Karenia brevis blooms uses an ecological approach based on anomalies derived from ocean color imagery. The same anomaly product used in Florida produces frequent false positives on the Texas coast. These failures occurred during wind-driven resuspension events. During...
