| Preliminary view of particle-associated optical backscatter in Chesapeake Bay before and after Hurricane Isabel, September 2003. "Warm" colors (reds and oranges) are indicative of sediment suspended in the water column, while "cool" colors (purples and blues) indicate lower concentrations of suspended sediment. The body of water in the center of the images is Chesapeake Bay; the estuary to the north is Delaware Bay. Atlantic Ocean waters can be seen in the lower right corner. Land is shown in gray. (A) Chesapeake Bay two days before Hurricane Isabel landfall on the Outer Banks of North Carolina. (B) Chesapeake Bay one day after landfall. Both Chesapeake Bay and adjacent continental shelf waters (lower right corner) now contain significantly higher levels of particulates than before. Original SeaWiFS (satellite ocean color) data provided courtesy of the NASA SeaWiFS Project and ORBIMAGE. Images processed by University of South Florida Institute for Marine Remote Sensing, a USGS co-op partner. |
