Description
United States Geological Survey, Menlo Park, California. Chief Scientist: Parke Snavely. Geophysical data (airgun, uniboom, radar) of field activity M-1-78-WO in Southern Strait of Georgia, Washington from 01/17/1978 to 01/23/1978
Location
Washington
Summary
Approximately 48 km of high-resolution seismic reflection profiles were obtained in the Strait of Georgia, Washington, from January 22 to 23, 1978. Tracklines were located by ships radar with variable range marker. The source of seismic energy used was a 400-600 Joule double-back Uniboom system with a recorder sweep rate of 1/4-second and a 1/4- or 1/2-second firing rate. Filter settings for the lines generally were 2900 Hz (high) and 850 Hz (low). Ships average speed was about 5 knots.
