The Martin Sponholz Papers, dated 1965-1968, are photographic slides of pictures Martin Sponholz took while he was a member of Operation Deepfreeze-66 Expedition and the Japanese Antarctic Research Expedition. Sponholz numbered and wrote captions beneath the slides. Those numbers and captions are used in the inventory list as titles. The slides marked DF relate to the United States Antarctic Research Program’s Deepfreeze-66 Expedition at Plateau Station, dating 1965-1966. The photographs Sponholz took on this expedition feature the building of the Plateau Station and its facilities, tools and instruments used to measure wind and temperature, and Antarctica’s landscape. The slides marked J relate to the photographs Sponholz took on Japanese Antarctic Research Expedition, dating 1967-1968. The photographs Sponholz took on this expedition feature meteorology equipment, Antarctica’s landscape and animals, and Syowa Base.

The Urbain J. Kinet Slides and Photographs Primarily of Landscapes and Wildlife in Antarctica and New Zealand, dated 1965-1969, contain color slides and photographs taken by Urbain J. Kinet. Kinet mostly shot the slides and photographs while assisting with entomological and geological research in Antarctica. The images mainly show landscapes and physical features of different locations in Antarctica, as well as images of Antarctic wildlife. Also included are color slides and photographs taken by Kinet in New Zealand and possibly other places. Many of the slides have captions written on them. The folder titles and dates are based on these captions and any additional information available from the Polar Rock Repository inventory of digitized slides. The photographs are dated from 1968-1969, which is when the prints were developed, but they were likely taken in Antarctica or New Zealand from 1965-1966.
