Title: High Energy Neutrino Astronomy from the Deep Sea

Abstract:
Messengers of the infinitely small, neutrinos provide us with valuable
insights into the fundamental laws of physics. Messengers of the
infinitely large, traveling on cosmological distances, they are
privileged probes of cataclysmic astrophysical phenomena.

 Neutrino Telescopes, buried deep in the sea/lake/ice are trying to meet
this double challenge. These detectors consist of a 3D matrix of
photomultipliers that detect the Cherenkov light inferred by the
displacement of charged particles produced when neutrinos interact
inside or around the detector.

 After a brief historical introduction, I will review the latest results
from the first generation deep-sea neutrino telescope ANTARES and the
expectations and status of the next generation detector KM3NeT, both
immersed in the Mediterranean Sea. In this context, synergies with Earth
and Sea sciences will be mentioned.

 Some emphasis will be placed on the potential of neutrino telescopes
for the determination of the neutrino mass ordering through oscillation
studies of atmospheric neutrinos in the GeV range (KM3NeT/ORCA) in the
Mediterranean Sea.
