15 Oct 2013: The spokespersons of the ANTARES, Baikal, IceCube and KM3NeT Collaborations established the Global Neutrino Network (GNN) by signing a memorandum of understanding “for a closer collaboration and a more coherent strategy among the four neutrino telescope communities, resulting in significant synergistic effects and benefits for each individual project to pursue its science goals”. The GNN is the first step toward a truely Global Neutrino Observatory.
