Abstract

The objective of this cruise was to conduct the final and complete field test of the LIGHTHOUSE situational awareness system for remotely operated vehicles, developed in the HVF 0068 Project LIGHTHOUSE. This included three divesof the ROV PHOCAin the Norwegian Sognefjord, during which the optical and acoustic sensors were validated. Moreover, as part of the EU H2020 project iAtlantic (grant agreement 818123), we investigated the response of pelagic deep-sea fauna to warmingand suspended sediment (which will be introduced to pelagic ecosystems by deep-sea mining activities). To this end, we captured the jellyfish Periphylla periphyllaand conducted shipboard experiments.
