RICHARD L. HALEY, Nimbus Program Manager, Space Applications, NASA, wrote of this picture taken September 9, 1964, from high over Antarctica: "In addition to the use of Nimbus data for meteorological purposes, the data have been utilized in such scientific disciplines as glaciology, geology, and oceanography.

"For example, here is a Nimbus I Advanced Video Camera System (AVCS) picture taken as the satellite passed 950 kilometers above the ice-covered Antarctic Continent. The picture covers an area 530 by 530 kilometers approximately in the Marie Byrd Land and Ellsworth Highland region.

"Just to the left of center is the Getz Ice Shelf. The dark areas delineating the coast are probably due to pressure ripples and faults in the ice which attenuate the reflectivity of the surface. Cirrus cloud bands and their associated shadows produce the .striations at the top of the picture.

"The Nimbus pictures have been extremely valuable in the mapping of the little-known Antarctic Continent. This and other pictures aided cartographers to relocate Mount Siple correctly 2° farther west on their maps. Mount Siple is visible as a gray-white spot just above the Getz Ice Shelf. Other mountain ranges in Antarctica were correctly relocated, and the configuration of the ice fronts in the Filchner Ice Shelf, Weddell Sea, and Princess Martha Coast areas were determined more accurately and completely than ever before."
