Abstract

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. A large portion of this data resides in a single repository with minimal metadata. 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 report, along with the accompanying USGS data release (Bosse and others, 2017), serves as an archive of seismic profiles with headers, converted Society of Exploration Geophysicists Y format (SEG-Y) files, navigation data, and geographic information system data files for digitized boomer seismic-reflection data collected from the Research Vessel (R/V) Erda during two cruises in 1990 and 1991. The Erda 90-1 geophysical cruise was conducted in two legs. The first leg included seismic data collected from the Hancock County region of the Mississippi Sound (Erda 90-1_HC) from June 4 to June 6, 1990. The second leg included seismic data collected from the Petit Bois Pass area of Mississippi Sound (Erda 90-1_PBP) from June 8 to June 9, 1990. The Erda 91-3 cruise occurred between September 12 and September 23, 1991, and surveyed the Mississippi Sound region just west of Horn Island, Mississippi.

Acknowledgments

Funding for this project was provided by the National Geological and Geophysical Data Preservation Program (NGGDPP), to help support the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center’s data rescue efforts to digitize analog paper seismic records contained within its local archives. Jolene Gittens (U.S. Geological Survey) assisted with the report layout and Web design. We also thank Noreen Buster, Julie Bernier (U.S. Geological Survey) and Ginger Range (Cherokee Nation Technology Solutions) for conducting scientific, editorial, and metadata reviews that improved the content and presentation of the report.

A special thanks go to Betsy Boynton, Kyle Kelso, and Heather Schreppel for technological help, as well as Jack Kindinger for being Chief Scientist on these cruises and preserving the collected data in a well-organized fashion.
