DOM being lowered into Antarctic ice
A digital optical module, or DOM, is lowered into the Antarctic ice, where it will collect data for the National Science Foundation's IceCube South Pole Neutrino Observatory. DOMs are attached to vertical "strings," frozen into 86 boreholes and arrayed over a cubic kilometer from 1,450 meters to 2,450 meters in depth.
