SeaWiFS sensor charts progression of red tide bloom in the Gulf of Mexico |
|
|
Since the onset of the event, SeaWiFS data have been acquired and processed by the UT Center for Space Research (CSR) and the Naval Research Laboratory at Stennis Space Center to support TPWD in mapping the location and extent of the red tide and target areas for aircraft overflights. The three groups are currently participating in a collaborative research effort to develop predictors for the occurrence of these events. Selected images show the evolution of the bloom since early August. On August 6, high levels of chlorophyll (shown in red) associated with organic laden sediment were observed by SeaWiFS at the outflow of the Atchafalaya River of Louisiana. Concentrations on the Texas coast (shown in green) were normal. The patches of red tide observed by fisherman produced red threads in the imagery near Sabine Pass in the August 17 image, and by August 31, the major outbreak is shown clearly in red in SeaWiFS imagery. The continuing bloom is shown in the September 5 and September 28 images.
