Seismology. Number 9. Crustal Structure Beneath the Gulf of Maine.

Abstract

Seismic refraction profiles obtained by ship-to-shore recording in the Gulf of Maine, and the velocity distribution in the upper part of the earth's crust, inferred from these profiles, are described. The surface layer has a velocity of 5.34 km/sec, and extends down to a depth of 5.1 km at Falmouth, Maine. Beneath, a layer with a velocity of 6.25 km/sec is found to slope upward to the east at 3 degrees over a distance of at least 80 km. A layer with a velocity of 7.5 km/sec appears at a depth of 16.7 km at Falmouth, Maine. The unusual submarine topography beneath the course of the shot boat is illustrated. (Author)
