Sidescan Sonar and Surface Sediment Samples off Sarasota

Sidescan Sonar and Surface Sediment Samples off Sarasota The surficial geology of an 11 by 15 km section of the inner continental shelf off Sarasota, Florida has been mapped. The map area extends from Sarasota Point to Buttonwood Harbor and offshore between approximately 3-m and 13 m water depths. The study is part of a larger program initiated by the U.S. Geological Survey to map the geologic framework and monitor modern processes that affect the western Florida coastal zone. This survey, and a second one off Indian Rocks Beach (Harrison, 1996), provide insights into the local variability of the surficial geology that cannot be obtained from the regional studies. The U.S. Geological Survey, in cooperation with the University of South Florida and Eckerd College, completed a bathymetric, sidescan sonar, high-resolution seismic-reflection, and surface sediment sampling survey of this inner shelf environment during May, 1995.
