The Pacific Ocean Neutrino Experiment (P-ONE) is a new initiative towards constructing a multi-cubic-kilometre neutrino telescope to expand our observable window of the Universe. The high energy telescope will be installed within the deep Pacific Ocean underwater infrastructure of . If funded, the P-ONE telescope for TeV鈥揚eV neutrinos stands to be a major scientific endeavour and a platform for major scientific collaboration in British Columbia.

Background
The Universe is opaque to very high-energy photons, limiting the horizon of 纬-ray astronomy above 100 TeV primarily to our Galaxy. Neutrinos allow for the exploration of the cosmos up to the highest energy frontier. Following the 鈥檚 discovery of an astrophysical flux of neutrinos in 2013 [; ], and the subsequent link between these neutrinos and a 纬-ray emitting blazar in 2017 [], a global effort has mobilized to establish dramatic improvements in the exposure to astrophysical neutrinos.

Ocean Networks Canada offers a new opportunity for the construction of a large-volume neutrino telescope. Among the various Ocean Networks Canada-powered nodes, the Cascadia Basin at a depth of 2,660 metres has been selected to host the Pacific Ocean Neutrino Experiment (P-ONE). P-ONE as a new telescope for TeV鈥揚eV neutrinos will build on a highly modular deployment and maintenance approach.
