Submerged Aquatic Vegetation - Gulf Islands - Mississippi

The Mississippi barrier islands, Cat, West Ship, East Ship, Horn and Petit Bois, were impacted dramatically by Hurricane Katrina on August 29, 2005. To determine potential impacts of the storm on island seagrass populations, seagrass maps were developed from digitized aerial true-color photography acquired on Oct. 15, 2003 (0.3 m resolution), and digital multispectral imagery acquired on Oct. 29, 2006 (1 m resolution). Seagrass areal coverage and distribution were quantified via digital image processing and visual image interpretation. Results were compared between the two dates to determine post-Katrina change.
