Sea-level and Storm Impacts on Estuarine Environments and Shorelines (SSIEES)

Research - Chronological geospatial assessment and quantification of episodic impacts
in wetland environments

Geospatial comparison over time.
A simple comparison between the 1848 U.S. Coastal and Geodetic Survey T-Sheet #243 map (left) and the 2006 U.S. Department of Agriculture (USDA) National Agriculture Imagery Product (right) for the Grand Bay region located at the border of Mississippi and Alabama. A digitized surface/shoreline from the 1848 survey is presented in red and overlain onto the National Agriculture Imagery Program (NAIP) image to highlight the extensive estuarine marsh-wetland area loss.

The goal of this task is to map, characterize, and quantify cumulative episodic event-driven loss in northern Gulf of Mexico coastal wetlands over the past century using available remotely sensed data. Achievement of this goal will provide spatially explicit estimates of wetland loss/gain caused by episodic large-scale drivers versus changes from persistent drivers such as sea-level rise and cumulative cold-front passages (Barras, 2003; Barras, 2006; Barras, 2009).
