Operation Deep Freeze is the general codename for a series of United States missions to Antarctica that began with Operation Deep Freeze I, launched in 1955–56 in preparation for scientific work planned as part of the International Geophysical Year (1957-58). Regular missions followed over the following decades, primarily to provide logistical support to researchers. This collection shows the men and operations of the United States Coast Guard Cutter Burton Island, which participated in eight Deep Freeze operations between 1967 and 1978. During these missions, “Burton Island was responsible for creating and maintaining aids to navigation, clearing channels through the ice for supply vessels, laying cables, delivering and dispatching the U.S. Mail at remote stations and vessels, search and rescue, fisheries patrol, law enforcement, and giving dental and medical treatment at remote Native Alaskan communities” (wiki). he mission shown here occurred between November 1972 and April 1973. The collection includes 25 black and white photographs, all approximately 8 x 10 inches, some with brief captions in pencil on the back. All in very good condition. There are images of the Burton Island breaking and stopped on the ice, supplies being inventoried near Campbell Island (sub-Antarctic New Zealand), an airlift, launching of a mini-submarine, crew members (some identified), penguins (emperor, Adelie, and chinstrap), walruses, a leopard seal on the flight deck, and men engaged in fantail jumping – a popular if somewhat dangerous form of amusement on rough seas. There are four additional photos of maps showing the route of the cruise, which arrived at McMurdo Station on January 30, 1973.
