This website provides an interface to browse, label, and download nearly 1000 rolls of digitized optical film containing data from the earliest large-scale ice-penetrating radar survey of Antarctica. The data available here was gathered in the late 1960s and 1970s as part of an Antarctic airborne geophysical survey. Conducted by an international consortium of American, British and Danish geoscientists, the airborne surveys used a converted American military C-130 long-range aircraft. The decade-long effort involved crisscrossing Antarctica repeatedly, covering a total of about a quarter million line-miles, and using ice-penetrating radar to peer beneath the surface down to a depth of about 3 miles.
