USGS - West Central Florida Coastal Studies Project Coastal Transect #5: Treasure Island, Long Key 343

Content Description

Abstract: A major goal of the West-Central Florida Coastal Studies Project was to investigate linkages between the barrier-island system along the west coast of Florida and offshore sedimentary sequences. Uninterpreted high-resolution "boomer" seismic data show limited penetration and a change from more continuous sediment cover nearshore to a more discontinuous distribution of sand waves offshore. Poor acoustic contrast between the Holocene sediment cover and the underlying pre-Quaternary bedrock is attributed, in part, to the weathered nature of the Neocene limestone. Some deformation of the pre-Quaternary bedrock is attributed to karst processes at depth. The modern sediment cover is typically less than 2 m thick, corresponding with the higher-relief portions of the sand waves and ridges seen here.
