University of Alaska,United States Geological Survey, Menlo Park, California. Chief Scientist: Roland Von Huene. Geological and Geophysical data (sidescansonar, samples) of field activity A-1-67-WG in Yakutat Bay to Nuka Bay, Gulf of Alaska from 01/01/1967 to 01/01/1967
Location
Gulf of Alaska
Summary
130 samples were taken on the shelf and in Yakutat Bay, and 2,000 km of continuous seismic profiles have been analyzed in 1967. Submerged glacial morraines were identified on the profiles in several areas, and one of them appears to form one all of Yakutat Sea Valley, in part controlling the course of this feature. The gross tectonic nature of the Continental Shelf was found to change near Yakutat Bay. Southeast of the bay the outer margin of the shelf is a northwest-trending anticlinal structure paralleling the coast, and the potential for petroleum is good is source rocks exist. West of Yakutat Bay, northeast-trending structures interrupt the coastal trend; their age and nature are important factors in evaluating the petroleum potential west of this area.
