1990 EDGE Experiment off of Virginia Coast

Abstract: The EDGE seismic experiment shot on the M/V GECO Searcher in September
1990 recorded seismic reflection profiles to 16 sec. in a 560 km grid
off the coast of Virginia. Shots of a 10,000 cu. inch, 2,000 psi
airgun array were recorded on 12 ocean bottom seismometers across the
continental margin, while 15 PASSCAL recorders formed a 110 km profile
across the Coastal plain. The experiment was conducted to analyze the
deep crustal structure in this area in relation to the Salisbury
magnetic anomaly, the East Coast magnetic anomaly, and magnetic
anomalies along the hinge line of the Baltimore Canyon Trough.
This dataset contains three component data from 16 different stations
operated on-shore.
