Up to 86 strings of 60 optical sensors each Depth between 1450 m and 2450 m in clear ice If a high-energy cosmic neutrino interacts, measure Čerenkov light from showering secondary particles Monitors all directions of sky 24 hours per day Could it detect SETI neutrinos? arXiv:0803.0409v1 [physics.pop-ph] 4 Mar 2008arXiv:0805.2429v3 [physics.pop-ph]
