| Description |
In June and July of 2004, the U.S. Geological Survey, in cooperation with the University of New Orleans, conducted geophysical surveys in Terrebonne Bay, Timbalier Bay, Lake Pelto, and Barataria Bay, Louisiana, and nearby waterbodies. This report serves as an archive of unprocessed digital boomer and chirp seismic reflection data, trackline maps, navigation files, GIS information, Field Activity Collection System (FACS) logs, observer's logbook, 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 more information on the seismic surveys see http://walrus.wr.usgs.gov/infobank/g/g104la/html/g-1-04-la.meta.html These data are also available via GeoMapApp (http://www.geomapapp.org/) and Virtual Ocean ( http://www.virtualocean.org/) earth science exploration and visualization applications.
