“…For this reason the experimental community is undertaking a relevant effort to construct giant Neutrino Telescopes (NT's). From this point of view, after the first generation of telescopes has proved the viability of the Cerenkov detection tech- nique under deep water (Balkanov et al, 1999) and ice (Ahrens et al, 2002) by detecting atmospheric neutrinos, one is probably on the verge of the first detections at the IceCube (Ahrens et al, 2004) telescope, being completed at the South Pole, and possibly at the smaller ANTARES (Spurio, 2006) telescope under construction in the Mediterranean. Additionally, ANTARES as well as NESTOR (Aggouras et al, 2006) and NEMO (Migneco et al, 2008) are involved in R&D projects aimed at the construction of a km 3 NT in the deep water of the Mediterranean sea, coordinated in the European network KM3NeT (Katz, 2006).…”
