Cables as part of Arctic Ocean Observing System (AOOS)

TrackPlenary
DescriptionSustained ocean in situ observations are sorely lacking in the Arctic. This limits the possibility to advance the research of climate, weather, ice-ocean processes, and geophysical hazards. SMART (Scientific Monitoring And Reliable Telecommunications) Cables with integrated sensors are in progress in the Arctic e.g., Far North Fiber, Borealis. To facilitate the sustained observation of the full water column the cables will need to support branching points connecting advanced underwater installations that extend up into the water column with instrumentation. The cabled super-sites will be cornerstones in a future Arctic Ocean Observing System (AOOS). Such cabled (and uncabled) super-sites equipped with acoustic sources and receivers will enable basin scale tomography (for temperature) and form an underwater acoustic navigation system (a la GNSS) for floats, gliders, and powered autonomous undersea vehicles, the latter electric vehicles benefiting from cabled docking stations for power and communication.
