The survey area extends 15km from Sarasota Point to Buttonwood Harbor. This study is part of a larger program initiated by the U.S. Geological Survey to map the geologic framework and monitor the modern processes that affect the western Florida coastal zone. This portion of the project included a reconnaissance high-resolution seismic and side-scan sonar surveys of the entire study area, detailed mapping to identify patterns of hard grounds and sediment cover, and coring of sediments to document historical development of the inner shelf and coastal system. Purpose: This GIS overlay is a component of the Sarasota, Florida ArcView GIS database and contains the analyses of 149 surface samples. Sediment samples were collected during May 2-8, 1995 aboard the R/V BELLOWS (operated by the University of South Florida). Supplemental_Information: Surficial sediment samples were attempted at 152 locations using an underway pipe sampler. Samples were recovered at 149 of these stations.
