Paper Abstract
The coastal region comprising the states of Louisiana, Mississippi, and Texas is frequently impacted by
meteorological events such as frontal passages and hurricanes. The region is also influenced by the
Mississippi river, which is seventh largest in terms of water and sediment discharge among the major rivers
of the world that strongly influences the physical and biogeochemical properties in the northern Gulf of
Mexico. NASA remote sensing data such as winds from QuikSCAT, sea surface height anomaly (SSHA)
from Jason-1, ocean color and sea surface temperature (SST) from MODIS satellite sensors were assessed
during the period that Hurricane Rita made landfall on 24 September 2005 along the Louisiana-Texas
border in the western Gulf of Mexico. QuikSCAT winds revealed the northwestward movement of the
hurricane and gradients in the distribution of wind speed around the hurricane center. Altimeter data
indicated changes in pattern of the SSH anomaly field and a displacement of the warm and cold core eddies
following the hurricane. Although limited by cloud cover, the MODIS 8-day average chlorophyll imagery
obtained before and after the hurricane indicated an offshore displacement of higher chlorophyll
concentrations while the MODIS 250 m resolution true color imagery showed high levels of suspended
particulate matter in the impacted coastal region. MODIS SST indicated a cooling of the surface waters
around and east of the track following Hurricane Rita. The use of multiple remote sensing products
provided better insights of the oceanographic response to Hurricane Rita.
