Via an electro-optical network of cables and subsea junction boxes the optical modules are connected to control stations on shore for electrical power, for detector control and for data transmission. Since the strings with optical modules move with the currents in the deep sea,

4818-544: The very different methods employed, its expected sensitivity is complementary to the direct dark matter searches performed by various experiments such as DAMA , CDMS and at the LHC . Detection of neutralino signals would also confirm supersymmetry , but is not generally considered very likely at the ANTARES sensitivity level. Other possible "exotic" phenomena that could conceivably be measured by ANTARES include nuclearites or magnetic monopoles . The first neutrino detections were reported in Feb 2007.
