Navy Electronics Laboratory events—the submerged voyage of USS "Nautilus" from the Pacific to the Atlantic, via the North Pole, in 1958, with NEL’s Dr. Waldo Lyon aboard as chief scientist and ice pilot. That same summer, the USS "Skate" cruised from the Atlantic to the North Pole and the central Arctic Ocean, surfacing 9 times through small holes in the ice cap. Dr. Eugene C. La Fond, head of NEL's Oceanography Branch, was chief scientist In March 1959, the "Skate" returned to the Arctic, under winter conditions, with Dr. Waldo Lyon as chief scientist, and for the first time, the nuclear submarine was
Ice cap climate Mountains, the Caucasus, and the Alps. Mars, like Earth, has ice caps at its poles. In addition to frozen water, Mars ice caps also have frozen carbon dioxide, commonly known as dry ice. In addition, Mars has seasons similar to Earth. The North Pole of Mars has a permanent water ice cap and a winter-only dry ice cap. On the south pole, both the water and carbon dioxide are permanently frozen. Europa, a moon of Jupiter, is covered with a permanent sheet of water ice, similar to Antarctica. Scientists theorize that it may have sub-glacial lakes similar to those seen
