Topographic Assessment of the Oculina Banks, Florida:
A GIS is being developed to characterize the habitats of the Oculina Banks. Using multi-media including side scan sonar, video, multibeam bathymetry and historical fish surveys, a habitat analysis is being performed to determine the health of the area. Results are being disseminated via cd-rom and Internet GIS. See www.uncw.edu/oculina for a complete description as well as GIS tools. Preliminary results can be found in:

Modeling Change in Back Barrier Marshes :
A GIS has been developed for Topsail and Masonboro Islands, in Southeastern North Carolina, to quantify change in the marsh habitats. Seven dates of high spatial resolution aerial photography, dating back to 1938, have been rectified, interpreted, and digitized to provide a series of temporal maps of the islands. GIS spatial analysis techniques have been utilized to quantify habitat change, develop spatial indices to model the potential for future change, and to investigate the geomorphological and topographical variability in the marsh habitats.
