Summary for Field Activity Number 1976-023-FA

Alternate Leg ID: FAY 018

Area of Operations: southeast Georgia Embayment, Georgia, United States, North America, North Atlantic

Dates: July 02, 1976 to July 15, 1976

Objectives: Geophysical reconnaissance of the southeast Georgia Embayment for regional environmental analyses.

Type of Activity: Seismic profiling

Information to be derived: Morphology

Summary: 13 lines were run normal to the coastline between 33 N and 29 30 N. Two lines comprised one long tie-line parallel to the shelf break. In addition, four short lines were run in the area between latitude 30 40 N to 31 10 N and longitudes 80 30 W to 80 W. The lines and numbering system was continued from FAY Cruise 017 to the north at 18. Lines on 018 were numbered from 18 to 32 and the dogleg following each line was considered part of the preceeding line. 12 sonobuoy refraction profiles were completed along lines 31 and 32, all on the Blake Plateau. Sonobuoy stations were numbered from 2 to 13 with #2 on the north and #13 on the south. 3.5 kHz: 2515 km; Sparker: 2808 km; Airgun: 3019 km; Sonobuoy: 12 stations, 268 km; Magnetics: 3019 km; Gravity: 2848 km.
