| Description |
From February through July of 1997, the U.S. Geological Survey conducted geophysical surveys of Lakes Dosson, Halfmoon and Round, Sebastian Inlet, and Indian River Lagoon, within west-central and offshore of the eastern Florida coast. Field activity 97LCA01 was conducted in cooperation with the Southwest Florida Water Management District (SWFWMD), and field activities 97LCA02 and 97LCA03 were conducted in cooperation with the St. Johns River Water Management District (SJRWMD). This report serves as an archive of unprocessed digital boomer sub-bottom data, trackline maps, navigation files, GIS information, cruise log, and formal FGDC metadata. Filtered and gained digital images of the seismic profiles are also provided. The archived trace data are in standard Society of Exploration Geophysicists (SEG) SEG-Y format (Barry and others, 1975) and may be downloaded and processed with commercial or public domain software such as Seismic Unix (SU). Example SU processing scripts and USGS software for viewing the SEG-Y files (Zihlman, 1992) are also provided. For detailed information about the hydrologic setting of Lakes Dosson, Halfmoon and Round and the interpretation of some of these sub-bottom data, see Metz and Sacks (2002) at http://fl.water.usgs.gov/PDF_files/wri02_4032_metz.pdf.
