Remotely sensed data from Landsat, MODIS, and SeaWiFS satellites were collected for time intervals corresponding to pre- and post-landfall of tropical cyclones between 2000 and 2009 in the north-central Gulf of Mexico. Satellite images were enhanced to highlight suspended sediment using a combination of cluster busting, enhancement, and classification techniques applied to color and infrared data. Results from the enhancements exhibit patterns associated with sediment transport and deposition related to coastal processes, storm-related sediment transport, post-storm pollutant transport, and sediment-current interaction. Collaboration between the Information Technology and Systems Center (ITSC) at Huntsville and the Geological Survey of Alabama and funding through the NASA Applied Sciences Program have made this project and the distribution of its data possible. Original satellite data and final enhanced imagery will be made publicly available for viewing and download via an online ITSC web service. The enhanced images and satellite data are anticipated to be beneficial to academic, government, and geospatial organizations involved in coastal decision-making activities in the Gulf of Mexico area.
