Abstract

Hurricanes Emily, Stan and Wilma made landfall along the Yucatan Peninsula (YP) in 2005 impacting regional coastal environments. The effects of these hurricanes on the coastal and oceanic waters around the YP were examined using multiple satellite sensor data such as winds from QuikSCAT, sea surface temperature (SST) from MODIS, and biooptical properties from the SeaWiFS ocean color sensor. QuikSCAT wind data revealed the hurricane paths along with typical changes in wind speed and direction and improved interpretation of the SST and ocean color data. SST imagery before and after hurricanes landfalling indicated variable extent of upper ocean cooling that varied with the hurricane track and its intensity. An examination of SeaWiFS-derived backscattering coefficient at 443 nm, an optical indicator of suspended particulate matter concentrations showed elevated levels of surface suspended material following the hurricane passages in both nearshore and offshore waters, likely due to resuspension and offshore transport. The use of multi-satellite data provided a greater understanding of the response and changes in sea surface properties to hurricanes in the YP.
