  The search for high energy neutrinos of astrophysical origin is being
conducted today with two water/ice Cherenkov experiments. New instruments of
higher performance are now in construction and more are in the R&D phase. No
sources have been found to date. Upper limits on neutrino fluxes are
approaching model predictions. Results are reported on the search for point
sources, diffuse fluxes, gamma ray bursts, dark matter and other sources.
