The Norwegian government just committed ~$4,000,000 to explore ecosystems in the Arctic Ocean. This new study includes ocean surveys of the Barents Sea in 2017 to the north of Norway and Russia using the new research icebreaker “Kronprins Haakon” that is being built now. The announcement was made today by Havforskningsinstituttet, Institute of Marine Research.
I have been excited about this new (light) icebreaker for almost a year, because it fills a global need to enhance observational scientific capabilities in the many coastal regions of the Arctic Ocean. A news clipping in the Barents’ Observer back in June 2013 caught my attention, because at the time I began to think, talk, write, and hope to work with German and Norwegian researchers to perhaps work together near Nioghalvfjerdsfjorden Gletscher (often called 79N Glacier) off North-East Greenland. This planing turned into a funded project 2 weeks ago.
More specifically, the German R/V Polarstern will deploy five University of Delaware acoustic Doppler current profiler moorings for 2-3 years across a submarine canyon off Greenland that cuts across the continental shelf from the deep Fram Strait towards the glaciers. We believe that the flow provides ocean heat that contributes to the melting their ice-shelves from below. Similar canyons exist in the Barents Sea where, I suspect, they also enhance exchange of deep with coastal waters to produce areas of much enhanced biological productivity, I blogged about biological ocean paintings off northern Norway (coccolithophores blooms) that eventually lead to fish. Lots of fishing in Norway … as well as oil and a Russian neighbor:
“… Norwegian marine scientists will also have an extensive coöperation with foreign counterparts in connection with the exploration of the Arctic Ocean. “Among other things, we want to build on the extensive coöperation we have had with Russian colleagues,” says Ingvaldsen. Norway and Russia have formally worked together in the Barents Sea for 55 years (since 1958) and the first joint survey was conducted as early as 1965 …” [From today’s public announcement]
Now back to the new Norwegian icebreaker: The helicopter deck is forward and thus separate from the aft-deck from where moorings and trawls and larger remotely operated vehicles are going to be deployed (and retrieved). Less visible from the above sketches is that the design includes a moon pool, that connects the deck through the hull into the water. Very few vessels have these as the engineering challenges to keep such a pool open in ice-covered sea are not trivial. I took these details from an online presentation that I found at the European Center for Information on Marine Science and Technology.
Equally challenging is the mount electronic equipment under the hull to project sound into the water and then listen to their echos to measure bottom depth, ocean current profiles, and structures within the sediment. All of these are sensitive and delicate sensors that process signals returned from stuff floating in the ocean (zooplankton), the bottom itself, and from stuff below the bottom.
Ocean currents are dear to my heart ever since starting my career in coastal oceanography off Delaware and Maryland. The new Norwegian ship has all the modern instrumentation with which to show the many mysteries and puzzles that the oceans still hold. Norway here supports ocean-going research that, I sometimes feel, is a vanishing venture as modeling, virtual realities, robotics, and social media dominate.
So, I applaud Norway to provide real and new observational capabilities to an increasingly aging and shrinking global research fleet. Norway has roughly 5 million people and builds one new ice-capable research vessel. For comparison, the US has 315 million people and builds one new ice-capable research vessel also. If you were a sea-going polar oceanographer with an interest in how climate change works, where would you prefer to work? The answer is not as simple as one may think.
