EMSO-Western Ligurian Site (European Multidisciplinary See floor Observatory and water column, Western Ligurian Site) is a second generation permanent submarine observatory deployed offshore of Toulon, France, as a follow up of the pioneering ANTARES neutrino telescope located nearby.
This submarine network is part of KM3NeT (https://www.km3net.org/) which has a modular topology designed to connect up to 120 neutrino detection units, i.e. ten times more than ANTARES. The Earth and Sea Science (ESS) instrumentation connected to KM3NeT is based on two complementary components: an Instrumented Interface Module (MII) and an autonomous mooring line (ALBATROSS).
The Module Interface Instrumented "MII" was deployed in May 2019 and cabled to the MEUST Node#1. Node#1 is cabled to the shore via the KM3NeT cable.
The MII provides data for temperature, conductivity/salinity, pressure, particles proxy (deduced from beam attenuation measured with a CSTAR transmissiometer). The MII collects data through an acoustic link from the instrumented mooring line ALBATROSS (https://doi.org/10.17882/74513) deployed at a distance of 2-3 kilometers. These data are being transferred daily for near real time visualisation.
