East-West seismic profile of McMurdo Sound, Antarctica
Includes bibliographical references. Includes illustrations. Seismic refraction and reflection data have been used to develop geophysical and geologic profiles across McMurdo Sound, from Cone Hill on Hut Point Peninsula, Ross Island in the east to the Strand Moraines in the west. Reflection stations...
