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.
