Content Description
Abstract: Erosion of marsh shoreline in the Grand Bay National Estuarine Research Reserve (NERR) has been occurring steadily throughout the past several hundred to thousands of years, since the pirating of the Escatawpa River by the Pascagoula River (Otvos, 1985). The Grand Bay NERR is located in the southeast corner of Mississippi and borders Alabama. This natural process is driven by relative sea-level rise (combination of sea-level rise and land subsidence) and wave attack, and is offset somewhat by the conversion of upland areas to wetlands. Today, however, the process of upland conversion is limited, and in many cases reversed, by development, making marsh erosion more problematic. This update on shoreline position, high erosion areas, and area loss in the Grand Bay NERR marsh system is meant to highlight recent trends associated with coastal erosion.
Purpose: The report largely represents analysis of field data collected by the Mississippi Office of Geology on the Mississippi coast. Analysis of data and subsequent conclusions conform to accepted geologic practices.
