Abstract: The camera being tested is a Heavy Duty Econo Geo VISION™ Borehole Camera System used for inspection of water wells, oil wells, mines, caves, tanks, pipes, shafts, caissons, and large and small voids. The camera will be used to inspect ice crevasses that are located in the active ice zone on the snow route from McMurdo Station to the South Pole Station. The ice crevasses are covered by snow bridges, and the air temperature in the ice crevasses can be as cold as -40°C. This camera will be passed down through a 2-inch-diameter hole made through the snow using a hot water drill. The current method of inspecting crevasses is to dynamite an opening in the snow and return a few days later (allowing time for the air to clear from the blast) and then lower a person through the opening and have that person do the inspection. The use of the camera should be safer and faster, eliminating the need to blast large holes in the snow bridges and have a person enter the crevasse on a rope.
