RICE
Radio Ice Cerenkov Experiment (RICE) is an experiment designed to detect the Cherenkov emission in the radio regime of the electromagnetic spectrum from the interaction of high energy neutrinos (greater than 1 PeV) with the Antarctic ice cap. The goals of this experiment are to determine the potential of the radio-detection technique for measuring the high energy cosmic neutrino flux, determining the sources of this flux, and measuring neutrino-nucleon cross sections at energies above those accessible with existing accelerators. Such an experiment also has sensitivity to neutrinos from gamma ray bursts, as well as highly-ionizing charged particles (monopoles, e.g.) traversing the Antarctic icecap. http://en.wikipedia.org/wiki/Radio_Ice_Cerenkov_Experiment
