Byrd Antarctic expedition (1933-1935); chief geographer and navigator

climatology and the problems of sub-freezing environments. In six
expeditions to Antarctica, Siple spent over four years in South Polar
Regions, more time than any other person. Siple brought back the first

the difficulty of adapting to a warm climate. One went on view at the
American Museum of Natural History in New York City.
