The U.S. Geological Survey (USGS) Coastal and Marine Geology Program has actively collected geophysical and sedimentological data in the northern Gulf of Mexico for several decades, including shallow subsurface data in the form of high-resolution seismic reflection profiles (HRSP). Prior to the mid-1990s most HRSP data were collected in analog format as paper rolls of continuous profiles up to 25 meters long. As part of the National Geological and Geophysical Data Preservation Program, scientists at the USGS St. Petersburg Coastal and Marine Science Center are converting the analog paper records to digital format using a large-format continuous scanner.
This data release serves as an archive of seismic profiles with headers, converted Society of Exploration Geophysicists (SEG-Y) files, navigation data, and trackline shapefiles for digitized boomer seismic data collected from the Research Vessel (R/V) Acadiana. The Acadiana 87-2 geophysical cruise included seismic data collected in the northern Gulf of Mexico, Chandeleur Sound, and Mississippi Sound from June 15-26, 1987. Data collection and processing methods are described in USGS Data Series 1047.
