Abstract

In April 1976, the U.S. Geological Survey, Office of Marine Geology conducted a geophysical and sediment sampling cruise in the northern Gulf of Alaska between Seward and Kayak Island (Fig. 1) to obtain data on seafloor hazards pertinent to the OCS oil and gas lease sales. Stormy weather interrupted the planned data collection, during which time supplemental profiles and samples were collected in Prince William Sound including Montague Strait, Valdez Arm, Port Valdez, and Columbia Bay (Fig. 1). High resolution seismic profile records were made using a 600 Joule Del Norte Minisparker along 1151 km of track lines as shown on maps 1 and 2. Sediment samples collected with grab samplers (58) and gravity core (3) and bottom camera stations (14) are also shown on the track line maps and on figures 2 and 3.

This report indicates the seismic reflection records and shipboard logs that are publicly available and includes track line maps and a text that; (1) shows examples of characteristic seismic profiles, (2) describes geologic hazards observed on specific profiles, and (3) includes summary descriptions of sediment samples and bottom photographs.
