Impassable Northwest Passage Open For First Time In History 528

An anonymous reader writes "The Northwest Passage, a normally ice-locked shortcut between Europe and Asia, is now passable for the first time in recorded history reports the European Space Agency. Leif Toudal Pedersen from the Danish National Space Centre said in the article: 'We have seen the ice-covered area drop to just around 3 million sq km which is about 1 million sq km less than the previous minima of 2005 and 2006. There has been a reduction of the ice cover over the last 10 years of about 100 000 sq km per year on average, so a drop of 1 million sq km in just one year is extreme.'"

        Not in any great hurry ; in theory, the opening of the Arctic Ocean could make development and/ or extraction of minerals somewhat cheaper in the immediate coastal regions. But once you're more than a few tens of miles from the coast, then you're going to find that the costs of building rail lines or pipelines (depending on if you're talking about minerals or oil) gets up to the level where it's just as cheap in the long run to go overland with rail. And that's not going to be a quick option. Then again, building port facilities isn't quick either, particularly if you've got no port to bring the building materials for building your port.

        Explorers looked for northwest passage from 1400s to 1900, mapping the artic area. in 1906 Roald Amunsen navigated the passage in an ice-fortified ship. Been done with other such ships since then.
      • Are you referring to the 1530s and Hernán Cortés? You're jumping the gun a little — it wasn't until 1576 that Martin Frobisher first tried to find the Northwest Passage. Of course, you could be referring to the 1630s as several attempts were made after this to find this passage that did not exist. Perhaps (but surely not) you're conflating the (prior lack of) existence of the Northwest Passage with the satellite record — which only stretches back about 30 years or so. Still, we know that the Northwest Passage has not been passable for well over 400 years.

        Now, sarcasm aside, I'm going to go out on a limb and guess that you don't agree with the scientific consensus on global warming. You no doubt extol the virtues of having an open mind and being skeptical. Has it occurred to you that the scientists are just as likely to have underestimated our impact as to overestimated it? In fact, evidence suggests that, being the conservative people that scientists are (not in the political sense, mind you), scientists have repeatedly underestimated our impacts. That doesn't mean that certain non-scientists aren't greatly exaggerating things, but I'm guessing (again) that it's the mainstream science [wikipedia.org] view that you're taking umbrage with.

              Well, Ben, there's nothing that rises to the level of courtroom proof in the way of evidence excavated yet no, but the concept is not exactly new.

              Basically, the Haida band, who are the indigenous First Nation of Haida Gwaii (the archipelago which you non-PC foreigners are probably more familar with as "the Queen Charlotte Islands") display such a number of cultural similarities to the Norsemen that many reasonable people find it less of a stretch to presume that there was contact between them than to assume a remarkable cascade of coincidences. Let us take an example, boat design.

              ""Yakutat," or "Northern-style" canoes include a variety of design forms, including a characteristic curve and swelling near the bow. The prow of the canoe gracefully curves up from the water and can be adorned by elaborate carvings."
              http://www.amnh.org/exhibitions/expeditions/treasure_fossil/Treasures/Haida_Canoe/canoe.gif [amnh.org]

              Now, contrary to the learned discourse above, these are not actually characteristic of Haida design. There is one other culture that designed its ocean-going vessels with those same "characteristic" traits. Care to guess what that culture was?
              http://www.geocities.com/dragar.geo/WSP/Pix/longship.gif [geocities.com]

              Those are just the first two images Google search came up with for each; if you look into it further, you'll find that the similarities are more striking than those two make apparent. Striking enough that when Haida/Tlingit take their canoes on cultural exchanges to Europe, they constantly get questions along the lines of "why did you make a longship out of a single tree trunk and paint it funny?", as Europeans just assume that the design is a conscious imitation of the Norse, not their own.

              Also, the Haida are physiologically distinct, rather dramatically so in fact, from every other American aboriginal culture; they are taller, whiter, grow facial hair, and produce significant quantities of brunettes and redheads.

              "Marchand also described the Haidas of Queen Charlotte Islands whom he visited in 1791. He found them not differing materially in stature from Europeans, better proportioned and better formed than the Sitkans and without the gloomy and wild look of the latter. Their color he found did not differ from that of Frenchmen, and several were less swarthy "than the inhabitants of our country places' (Edward L. Keithahn, MONUMENTS IN CEDAR: The Authentic Story of the Totem Pole, Bonanza books, New York 1971:19-23, emphases supplied)."

              This is not consistent with Haida mixing with Asian genetic pools, or any other Western North American genetic pool, or hell any other race bordering the entire Pacific for that matter. On the other hand, this is remarkably suggestive of significant admixture with a Scandinavian genetic pool, yes?

              Anyhoo, if you'd like to look further into the theory that the "Vinland" of the sagas is actually British Columbia, specifically the Cowichan Valley of Vancouver Island, here's a page for you:

              Actually living in British Columbia, I can attest to the plausibility of all the little details. The one that really struck me was his identification of the Oregon grape with the always-problematic 'grapes' of the sagas. As pointed out on this page, the presentation in the sagas does seem facially invalid:

              "As for the grapes in the Sagas, James Robert Enterline wrote in VIKING AMERICA (1972):
              In the Saga of Eirik the Red, after Thorhall the Hunter went off by himself, some writers have inferred that he found grapes and ate of them, becoming intoxicated, for he was discovered on a steep crag where:" he lay gazing up into the air with wide-open mouth and nostrils, scratching and pincing himself and muttering something ."

        Nobody claimed that Amundsen has not done it back then. The claim is that the passage now is practicable in one go, because the whole passage is open. Amundsen needed several years to make it all the way through in bits and pieces. And he couldn't have done it in any larger ship than the one he used, due to the water water being as shallow as 3 feet. Not exactly an economically viable solution.

We don't know anything about the entire passage prior to 400 years ago, but people have been interested in trying to find a way through continuously since then. If the passage in the last 400 years was ever as wide as it is now, it would have been easily spotted. Have you seen [bbc.co.uk] the satellite pictures?

        Smoothness. Just take a look at the curves, and you'll see lots of cycles, big and small but these are changes that happen over thousands (and in some cases, millions) of years. What we see today is much bigger than "the little ice age" and the yearly variations, it goes straight up and coincides with our industrialization and CO2 emissions. Just because our ability to accurately predict say a storm center months in advance is poor, we know what normal variation is and this isn't it.

      It has the potential to be incredibly lucrative, yes.

      Most of the passage indisputably passes between islands all internationally recognized as Canadian. Territorial waters [wikipedia.org] is defined as 12 nautical miles (22 km) from the land, and a quick check using Google Earth shows most of these islands are less than 44 km apart at their closest points. Once you're in the Beaufort Sea, then yeah you're in international waters.

      Unfortunately the US and European countries don't have many comparably close-lying islands for comparison, but it would be like claiming the Shelikof Strait between Alaska and Kodiak Island were international waters.

      The US and Europe want the passage "international" for the convenience and cost savings, which is understandable. But their wanting to make it international also means they want to strip Canada of its obligation to protect its environment--witness the callous disregard of the effects of dumping bilge oil/water [elements.nb.ca] just last year.

      Obviously, Canada currently is in no position to enforce its sovereignty in the north due to its underfunded military, but that is a separate issue. The Arctic and Antarctic areas are one of the last areas on earth relatively unspoiled by human contamination, and it disgusts me that those largely responsible for screwing up the rest of the world, now want to finish the job.
