Summary for Field Activity Number 1989-002-FA

Alternate Leg ID: F2-89-NC

Area of Operations: Gulf of the Farallones, California, United States, North America, North Pacific

Dates: January 12, 1989 to January 28, 1989

Objectives: The objectives of cruises 89001 and 89002 were to obtain a baseline data set of high-resolution sidescan sonar imagery, single-channel geophysical profiles (high- resolution) of the shallow sub-bottom, intermediate-penetration 40 cubic inch airgun profiles, and surface sediment samples. The baseline data set was designed to allow us to characterize and understand this shallow segment of the continental margin off San Francisco, and to serve as a preliminary database for subsequent, more detailed and site specific studies.
