Developing an Underwater Network of Ocean Observation Systems With Digital Twin Prototypes—A Field Report From the Baltic Sea

During the research cruise AL547 with RV ALKOR (October 20-31, 2020), a collaborative underwater network of ocean observation systems was deployed in Boknis Eck (SW Baltic Sea, German exclusive economic zone (EEZ)) context project ARCHES (Autonomous Robotic Networks to Help Modern Societies). This realized via Digital Twin Prototype approach. that period different scenarios were executed demonstrate feasibility Twins an extreme environment such as underwater. One showed collaboration stage IV their physical counterparts on seafloor. way, we address question, whether represent feasible approach operate mobile ad hoc networks for and coastal observation.
