Studying optical water properties with atmospheric muon events in KM3NeT/ORCA — •Martin Schneider for the ANTARES-KM3NET-ERLANGEN collaboration — ECAP, Friedrich-Alexander-Universität Erlangen-Nürnberg

KM3NeT-ORCA is an underwater neutrino detector featuring a dense configuration of optical modules, designed for the detection of atmospheric neutrinos down to the low-GeV energy regime. Located in a deep-sea environment, the detector performance depends on the optical water properties. In this talk, a study of the optical properties of the sea water surrounding the ORCA detector is presented. For this, a sample of atmospheric muons is compared to sets of Monte Carlo simulations obtained by varying the light attenuation length.
