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 an ice cap climate. However, this theory is disputed, and even proponents suggest there was an area of periodic melting near the equator. The two major areas with ice cap climates are Antarctica and Greenland. Some of the most northern islands of Canada and Russia also have ice cap climates. In addition, a large portion of the Arctic Ocean near the North Pole remains frozen year round, effectively making it an icecap climate. The Arctic Ocean is located in the Arctic region. As a result, the northern polar ice cap is the frozen part of that ocean's surface. The only
