Observations of diffuse fluxes of cosmic neutrinos
  In this contribution the current observational results for the diffuse flux of high-energy astrophysical neutrinos are reviewed. In order to understand the science implications, the measurements in different detection channels are discussed and results are compared. The discussion focuses is the energy spectrum, the flavor ratio and large scale anisotropy.
