Query: Status of the NEMO Project   The NEMO project aims at the search, development and validation of key
technologies for the construction, deployment and mantainance of an underwater
Cherenkov km3 neutrino telescope in the Mediterranean Sea. Moreover, the NEMO
Collaboration carried out a long term exploration of a 3500 m deep sea site
close to the Sicilian coast; the study has shown that it is optimal for the
installation of the detector. A Phase-1 project, which is under way, will
validate the proposed technologies for the km3 detector on a Test Site at 2000
m depth. The realization of a new infrastructure on the candidate site (Phase-2
project) will provide the possibility to test detector components at 3500 m
depth and will allow also a continuous monitoring of the site.
