Magnetometer traverse on Plum Island near Newburyport, Massachusetts
Several large faults of regional tectonic significance circle around Boston and disappear offshore at Plum Island south of Newburyport, Massachusetts (Castle and others, 1976; Barosh and others, 1977). The traces of these faults are, in places, well defined by aeromagnetic anomalies (Harwood and Zietz, 1977), The purpose of this traverse was to get a close look at the magnetic signatures of these faults on the ground before attempting to trace them offshore using ship-towed magnetometer.
