Abstract
Shelikof Strait, situated between the Kodiak Island group and the Alaska Peninsula (Fig. 1), is included in OCS oil and gas lease area 60. Environmental geologic studies are being conducted by the U.S. Geological Survey prior to the scheduled September 1981 sale date. Seismic-reflection records, collected with 40- to 95-cm3 airgun, 800-joule minisparker, 800-joule boomer, and 3.5-and 12-kilohertz systems and covering over 6,400 km of trackline have been examined to identify geologic conditions at or below the seafloor that might affect petroleum operations. Of the total trackline distance, 865 km were collected in June 1980 aboard the Geological Survey's ship R/V S.P. LEE. The remainder were collected by Nekton Inc. in 1979, under contract to the USGS (Fig. 2). Sediment samples were collected at 42 stations on the June 1980 cruise for geological and geotechnical analysis (Fig. 2).
The purpose of this report is to present physical and chemical measurements that have been made on sediment samples and to give a preliminary geo-environmental assessment of Shelikof Strait, based on presently completed analyses of the geophysical records and sediment samples.
