High-Resolution Seismic Reflection Profiles collected August 4 to 28, 1979, between Cape Hatteras and Cape Fear, North Carolina and off Georgia and Northern Florida (Cruise GS-7903-6).

摘要

The U.S. Geological Survey in cooperation with the U. S. Bureau of Land Management collected single-channel high-resolution, seismic-reflection data for 3290 km of traverse off the southeastern United States between Aug. 4-28, 1979. These data were collected from the Research Vessel JAMES M GILLISS (Cruise GS-7903-6) as part of a program to assess environmental aspects of offshore petroleum and hard minerals development. The three areas of operation (fig. 1) and the purposes of data acquisition were as follows: Area 1: Continental Shelf, Slope, and Rise from Cape Hatteras to Cape Fear, North Carolina. Purpose: Regional geologic hazards and shallow stratigraphic study surrounding the Lease Sale 56 area. Area 2: Continental Shelf (Florida-Hatteras Shelf) 30°N to 32°N, offshore northern Florida and Georgia, Purpose: To assess possible geologic constraints to offshore development related to Oil and Gas Lease Sale 43. Area 3: Red Snapper Sink and northern Florida Shelf. Purpose: To study buried karst in the subsurface of the shelf and specifically to investigate karstification at Red Snapper Sink, Single-channel, high-resolution, seismic-reflection and echo-sounder records were taken for all areas. In the Southeast Georgia Embayment, Uniboom records (1,352 km of traverse) were also collected.
