German Ship Completes Historic Arctic Expedition (bbc.com) 23

The German Research Vessel Polarstern has sailed back into its home port after completing a remarkable expedition to the Arctic Ocean. The ship spent a year in the polar north, much of it with its engines turned off so it could simply drift in the sea-ice. From a report The point was to study the Arctic climate and how it is changing. And expedition leader, Prof Markus Rex, returned with a warning. "The sea-ice is dying," he said. "The region is at risk. We were able to witness how the ice disappears and in areas where there should have been ice that was many metres thick, and even at the North Pole -- that ice was gone," the Alfred Wegener Institute scientist told a media conference in Bremerhaven on Monday.

RV Polarstern was on station to document this summer's floes shrink to their second lowest ever extent in the modern era. The floating ice withdrew to just under 3.74 million sq km (1.44 million sq miles). The only time this minimum has been beaten in the age of satellites was 2012, when the pack ice was reduced to 3.41 million sq km. The downward trend is about 13% per decade, averaged across the month of September. "This reflects the warming of the Arctic," said Prof Rex. "The ice is disappearing and if in a few decades we have an ice-free Arctic -- this will have a major impact on the climate around the world."

    They travel under the arctic ice quite a bit. Do they contribute data to science or do they keep this information to themselves?
    • They probably contribute some data. But not a lot. I am sure the Russians and the Americans especially don't necessarily want to give up where they are or where they have been.

      Other Navy vessels may be a bit more open. As it is tough to hide where an aircraft carrier is, so they may be more apt to share some findings.

  • At least we were warned.
  • So far the text books I read said that ice was just the solid state of water. And historic remnants of bio-mass, being an indicator of living organisms, have been found in much more abundance where/when ice was absent than where/when ice covered the planet. When has ice been re-classified as an organism that can "die"?
  • ... mention volume or average thickness, which is just as, or even more, significant?
  • Why isn't Canada doing this research? Canada has infinitely more Arctic coastline than Germany has, and is proportionally more affected by Arctic weather than Germany is, so why isn't Canada doing this research? Where are all those Arctic research vessels that Canada should have built? The Arctic coastline research stations? The trans-polar atmospheric research flights? The under-sea data-collection pods? Where is Canada in all of this?

      If you're interested in the project, I would suggest skipping the news article and just reading the project site instead: https://mosaic-expedition.org/ [mosaic-expedition.org]

      For starters, it's not "just" Germany, there are 17 participating countries, Germany simply put up the majority of the funding and is leading the expedition. German interest in the Arctic is nothing new: https://en.wikipedia.org/wiki/... [wikipedia.org], but in this case is also driven by political and economic interests - namely, the opening up of new shipping routes, oil

      • Whenever I point out a thawing arctic will open up new opportunities for oil and gas exploration someone always seems to get upset.

    • Well, Germany is a much biger exporter.

    • Where is Canada in all of this?

      The University of Calgary, the University of Manitoba, the University of Victoria and the University of Waterloo are participating in this project.

      Actually, if too much of that ice melts, it could stop ocean currents that currently prevent Northern Europe from turning into a frozen wasteland. So Germany definitely has a stake in this.

  • Or a disc, 2182km (1354mi) in diameter.

    Much easier to imagine.

    That's not a lot

  • Imagine if Russia's northern coast no longer freezes in winter, they could become a significant naval power.

    More, if Arctic sea routes become feasible, then cargo ships going between the Atlantic and Pacific can choose the Arctic route instead of Suez Canal or Panama Canal, then Russia's navy will have more influence on global trade.

    Oil ships from Middle East can go west from Mediterranean Sea, out to Atlantic, turn north, around Norwegian Sea and go east along Russia, then south through Bering Sea and all

    • Imagine if Russia's northern coast no longer freezes in winter, they could become a significant naval power.
