IceCube is a cubic-kilometer ice-Cherenkov neutrino detector located at the South Pole. It is uniquely able to measure atmospheric neutrinos up to very high energies. Because of a matter effect in the earth, this makes it an exceptional detector to search for eV-scale sterile neutrinos. Sterile neutrinos are motivated by several anomalies in neutrino oscillation experiments. A high-statistics sterile search in IceCube is forthcoming, necessitating a careful treatment of the atmospheric neutrino flux uncertainties.
