Abstract:

Seismic, gravimetric, altimetric, and magnetic observations made along oversnow traverses in Marie Byrd Land and vicinity in 1959 and 1960 have provided a reconnaissance picture of this part of West Antarctica. The ice sheet surface slopes gently from a high in the region of the Executive Committee Range southwestward to the Ross ice shelf, but elsewhere exhibits a more complicated topography affected by the rugged subglacial relief. Before the formation of the ice sheet, a large island probably extended unbroken from the volcanic Executive Committee Range or Crary Mountains in the east to Edward VII Peninsula in the west, bounded on the north by open ocean and on the south by the Byrd subglacial basin.
