Recently, an opportunity for a pathfinder mission towards a new neutrino telescope appeared in the Pacific Ocean. An existing deep-sea electrooptical infrastructure maintained by Ocean Networks Canada could pose as the base towards a potential new large-volume neutrino telescope. Two groups from Technical University Munich and the University of Alberta pursued the optical characterization of the 2.6 km deep site calledCascada Basinwithin the scope of the “Strings for Absorption length in Water” (STRAW) project. We present a summary of the 1-year construction timeline, impressions of the detector performance and first results.

AbstractThe STRings for Absorption length in Water (STRAW) are the first in a series of pathfinders for the Pacific Ocean Neutrino Experiment (P-ONE), a future large-scale neutrino telescope in the north-eastern Pacific Ocean. STRAW consists of two $$150\,\mathrm {m}$$ 150 m long mooring lines instrumented with optical emitters and detectors. The pathfinder is designed to measure the attenuation length of the water and perform a long-term assessment of the optical background at the future P-ONE site. After 2 years of continuous operation, measurements from STRAW show an optical attenuation length of about 28 m at $$450\,\mathrm {nm}$$ 450 nm . Additionally, the data allow a study of the ambient undersea background. The overall optical environment reported here is comparable to other deep-water neutrino telescopes and qualifies the site for the deployment of P-ONE.
