Exciting deployment on the ARCA site!

15 April 2021 – During the last few weeks – despite the pandemic – the KM3NeT Collaboration worked hard to make five new detection units for ARCA ready for deployment. Spooled on their launching vehicles they arrived at the harbour of Malta where a team of KM3NeT technicians, engineers, and scientists inspected thoroughly the units for the last time before they were loaded onto the Miss Marilene Tide of the FUGRO company. In the early morning of 8th April the ship sailed out toward the IDMAR site of ARCA near Sicily for an amazing sea operation. After installing several new components for the seafloor network, on Monday 12 April the deployment of the five new detection units began.
