摘要:
Shots of 1000, 2000, and 3000 lb of TNT, detonated on the bottom of the 150‐f (fathom) Northeast Trough of the Gulf of Maine, were monitored at deep hydrophone locations on the continental slope off the United States of America, Bermuda, and the Antilles. Four types of arrivals were received from these shots: (1) ground arrivals, which were received at distances up to 250 miles from the shot; (2) direct arrivals that traveled along great circle, all‐water paths to receivers up to 1800 miles away; (3) indirect arrivals that traveled down the Northeast Trough and thence to the receivers; and (4) reflections from seamounts that lie off the mouth of the Northeast Trough.
