Title: A technique for measuring the sea water optical parameters with a dedicated laser beam and a multi-PMT optical module

The KM3NeT research infrastructure will be a deep sea multidisciplinary observatory in the Mediterranean Sea housing a neutrino telescope. Accurate knowledge of the optical properties of the sea water is important for the performance evaluation of the telescope. In this work we describe a technique for the evaluation of the parameters describing the scattering characteristics of the sea water using one multi-PMT optical module that detects scattered optical photons which are emitted from a laser. Our results show that we are able to determine these parameters with satisfying precision and are able to resolve the scattering length values with less than half a meter accuracy.
