Purpose
|
To provide information on the thickness and distribution of
Quaternary deposits, to identify folds and faults that deform them, and
to provide a basis for assessing geoenvironmental hazards.
|
|
|
Information to be Derived
|
Seismic reflection profiles.
|
|
|
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 ship's 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). Ship's average speed was about 5 knots.
