Composite digital sidescan sonar mosaic of Sarasota, FL
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 the inner shelf environment along the western Florida coast. 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

Subbottom and Sidescan Sonar Data Acquired in 2015 From Grand Bay, Mississippi and Alabama
공공데이터포털
From May 28 to June 3, 2015, the U.S. Geological Survey (USGS) conducted a geophysical survey to investigate the geologic evolution and estuarine sediment thickness in Grand Bay, Alabama and Mississippi. Specific objectives were to document the age and accumulation patterns of estuarine sediment to advance our understanding of sediment exchange with the adjacent marsh and sources of sediment to the coastal ocean. This investigation is part of the USGS Sea-level and Storm Impacts on Estuarine Environments and Shorelines (SSIEES) project. SSIEES seeks to better understand material exchange between marshes and adjacent estuarine water bodies along the northern Gulf of Mexico and the Atlantic coast, and determine the role extreme events (hurricanes, floods, and strong frontal systems) and sea-level change have on coastal change. This publication serves as an archive of unprocessed, digital chirp subbottom and sidescan sonar data, geographic information system (GIS) data and formal Federal Geographic Data Committee (FGDC) metadata, as well as processed sidescan sonar mosaics. Processed subbottom profile images are also provided in the "images" folder of 2015-315-FA_arc.zip. The archived subbottom trace data are in standard Society of Exploration Geophysicists (SEG) SEG Y revision 0 format (Barry and others, 1975) and may be downloaded and processed with commercial or public domain software such as Seismic Unix (SU). The raw sidescan sonar backscatter data are in standard eXtensible Triton Framework (XTF)format. These data are available for viewing using GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean (http://www.virtualocean.org/) multi-platform open source software. In addition, these data files can be downloaded from the USGS Coastal and Marine Geoscience Data System (https://cmgds.marine.usgs.gov).
