  ABSTRACT: Loss of marshlands in the Mississippi Delta plain of Louisiana threatens the future of the region’s economy, one which is heavily reliant on coastal wetland resources. This study builds on previous remote sensing investigations over the Barataria and Breton Sound Basins to make increasingly detailed assessments of changes occurring in coastal wetlands of southern Louisiana from both human extractive activities and repeated hurricanes. We set out to answer two scientific questions: 1) What are the bio-geophysical nature and the areal extent of changes in coastal shorelines and wetlands of the Barataria and Breton Sound basins over the past four years of intensive hurricane activity? 2) How have marshland/water boundaries in the probable impact areas of the Mid-Barataria and Mid-Breton sediment diversions recently changed in the landscape of water and wetland-covered patches?
