Seismic-reflection data on the eastern U.S. continental shelf acquired by M. V. L'OLONNOIS as part of the Atlantic Margin Coring Project (AMCOR) of the U.S. Geological Survey, July-September 1976
In 1976 the U.S. Geological Survey undertook a program to sample the eastern United States Shelf for stratigraphic information by drilling a set of core holes. Results of this Atlantic Margin Coring Program (AMCOR) have been reported by Hathaway and others. Sites were chosen from seismic-reflection data and were reviewed by a safety panel to minimize the risk of penetrating any hydrocarbon accumulation which might lead to environmental contamination.
The M-V-L'OLONNOIS, the service ship for the drilling operation, was fitted with seismic-reflection profiling equipment (listed below), to run seismic-reflection profiles before drilling began on each hole. This provided additional assurance that no closed structures would be penetrated and allowed minor adjustment with the site selection. A total of 491 km of high-resolution seismic profiles was collected on 22 sites.
Equipment used (specifics for each site noted on records):
Bolt Air Guns 1-40 cubic inch chambers
EPC Recorder
Teledyne Minisparker (last two sites)
Navigation used two Internav 101 Loran-C receivers.
