Abstract : The results of six sonobuoy wide angle reflection profiles in the Southern Chukchi Sea show that from 200 to 700 meters of unconsolidated sediments with acoustic velocities less than 2 km/sec overlay 1-1 1/2 kilometers of sandstones and shales with velocities in the range of 2.1 to 2.8 km/sec. A higher velocity formation of approximately 4 km/sec was found at two of the six stations. These results show that extensive deposition, as well as marine erosion, has played an important role in making the Chukchi Sea floor the flat feature that it is today. (Author)
