| Purpose | 1. Collect high-resolution seismic profiles at the Navy test site to map the shallow stratigraphy and velocity structure. 2. Measure the signature of three seismic sources (40-in3 airgun, 80-in3 watergun, 15-in3 watergun) frequently used with the multichannel seismic system. 3. Expand the multichannel seismic grid of the Long Island Platform in order to map basement and sub-basement structures. 4. Trace the northern and southern extents of the New York Bight fault and determine the youngest reflector which is offset. | ||||||||
| Location | Long Island Sound, Long Island Platform, New York, Connecticut, United States, North America, North Atlantic; | ||||||||
| Summary | Cruise was successful in completion of the objectives initially laid out. This was a "cruise of opportunity" in that NUSC provided the ship time. I heartily recommend future joint efforts based on the success of this effort. 12-channel multichannel: 1098 km; Minisparker: 411 km; 3.5 kHz: 1509 km; Magnetometer: 37 km. | ||||||||
