Beach Nourishment in the Gulf of Mexico Attempts to stabilize the shore can greatly influence rates of shoreline change. Beach nourishment in particular will bias rates of observed shoreline change toward accretion or stability, even though the natural beach, in the absence of nourishment, would be eroding. Trembanis and Pilkey (1998) prepared a summary of identifiable beach nourishment projects in the Gulf Coast region that had been conducted before 1996. Those records were used to identify shoreline segments that had been influenced by beach nourishment. Supplemental information regarding beach nourishment was collected from agencies familiar with nourishment projects in the State. All records were compiled to create a GIS layer depicting the spatial...

To meet these needs, the USGS has produced a comprehensive database of digital vector shorelines by compiling shoreline positions from pre-existing historical shoreline databases and by generating historical and modern shoreline data. Shorelines are compiled by state and generally correspond to one of four time periods: 1800s, 1920s-1930s, 1970s, and 1998-2002. Each shoreline may represent a compilation of data from one or more sources for one or more dates provided by one or more agencies. Details regarding source are provided in the ‘Data Quality Information’ section of this metadata report. Shoreline vectors derived from historic...

The extension is designed to efficiently lead a user through the major steps of shoreline change analysis. This extension to ArcView contains three main components that define a baseline, generate orthogonal transects at a user-defined separation along the coast, and calculate rates of change (linear regression, endpoint rate, average of rates, average of endpoints, jackknife).

In the Gulf, this species occurs throughout estuaries, shallow nearshore waters, and on reefs located near river mouths. Habitat: Large populations of this benthic invertebrate are found in the large estuarine bays and sounds of the Gulf (with most concentrations found within 10-meter depths). Sedentary in character, this invertebrate attaches in clusters to shell reefs, firm mud/shell bottoms and other hard substrates. Feeding and Behavior: The American oyster...
