Description
We review the present status of the search for ultra-high energy cosmic neutrinos with the conventional methods. The IceCube neutrino observatory has currently realised the best sensitivity on detection of neutrinos in the energy range around EeV, by the standard neutrino detection technique measuring ultra-violet Cherenkov light emissions. The most updated results from the data obtained by the increased instrumentation volume of the IceCube optical sensor array are reported, followed by discussions on its implication to origin of ultra-high energy cosmic rays. The another conventional technique using deeply penetrating airshowers also provides a capability to search for ultra-high energy neutrinos by a giant cosmic ray airshower detector. We briefly mention the published results obtained by the Pierre Auger observatory and the future outlook by the planned JEM-EUSO mission.
