Abstract
Results of five seismic refraction lines shot by the U.S. Geological Survey in the Gulf of Alaska between Icy Bay and Kayak Island indicate the following: (1) The Continental Shelf is underlain by as much as 11 km of sedimentary rock of probable Tertiary age where refraction velocities range from 1.2 to 5.5 kilometers per second; (2) a section approximately 5 km thick, which has velocities of 4.1-5.5 km/s and which could represent the Orca Group (lower Tertiary), is present in the western part of the study area but not in the eastern part; and (3) consistent basement velocities of approximately 7.0 km/s could indicate oceanic crust underlying the continental margin.
