Page 87 - Geological Observatory at Columbia University, using a new sea gravimeter developed by Anton Graf, of Munich. The instrument was mounted on a gyro-stabilized platform installed aboard the USS Compass Island. Gravity values for ocean areas have, in the past, had to be measured in submarines submerged to quiet depths. Difficulties in obtaining and fitting submarines for this purpose greatly restricted the accumulation of gravity data for the 70 percent of the earth's surface that is covered by water....

Page 51 - November 19, 1957, to February 20, 1958 (see fig. 9). It found that from the boundary of the Ross Ice Shelf to the Sentinel Mountains the underlying topography is alpine, with ice thickness varying between 2,000 and 9,000 feet. All but a few peaks of the rock floor are at present below sea level ; the major portions are far enough below sea level to be under water even if the ice were removed and the land were allowed to rise, as it would without its great burden of ice. The second leg of the Byrd...
Page 64 - ... bring hot material up toward the bottom of the crust in regions of uplift and return this material, which has cooled in the meantime, back down toward the core of the earth in regions of downwarp. In fact, the convection currents themselves may be the cause of the uplifted (plateau) regions and down warped (trench) regions.
