Arctic Ocean Survey May Reveal Lost World 194

Posted by Hemos from the and-nessie-will-be-there dept.
core plexus writes " A new survey of the depths of the ice-capped Arctic Ocean as reported at Reuters, BBC, and others, could reveal a lost world of living fossils and exotic new species from jellyfish to giant squid, scientists said on Thursday. They speculated that Arctic waters might hide creatures known only from fossils, such as trilobites that flourished 300 million years ago. The international scheme will include probing a 12,470-foot abyss off Canada described by project leaders as the "world's oldest sea water -- a vast, still pool unstirred for millennia, walled by steep ridges and lidded with ice." Bring on the "Jurassic Park" references."

    as an ocean engineer I feel compelled to point out that exploring the depths of the ocean is an assload harder than exploring space. Accordingly we've explored far less of it than space. Technologies are advancing but most of them are directed towards making existing technologies more efficient. We really don't have any improvments for reaching really deep areas and are still using technology pioneered in the 70s.

        You could use a different approach. Consider a geometrical inversion of the world at the surface of the earth, thus the center of the earth gets mapped to infinity, by setting the radius of the earth to 1 and mapping every vector of the length d to a certain point A to the vector in the same direction, but of 1/d length, thus pointing to A'.

        For instance the moon is about 50 times the radius of the earth away, so his image would be projected somewhere at 1/50 of the earth's radius, or just 85mls from the center of the earth. You can use other scaling functions but you will always end with a similar discrepancy. If you use 1/sqrt(d), A' will be somewhere at about 700mls from the center of the earth... still far away from everything we reached until now.

        There have been men on the moon, but no one deeper than 8mls from the earth's surface. Basicly we barely have scratched the surface of the earth yet, with even the deepest holes ever drilled lurking somewhere at the 7mls point (don't have the current number right here).

        Actually, the degree to which we have probed space with light and radio telescopes FAR exceeds that of the world's oceans. A vaccuum allows most forms of energy to travel through it, while water does a great job of attenuating most EM radiation, leaving sound to be the primary method of remote imaging.
        Of course we could never have those beautiful global shaded relief seafloor images if it wasn't for satellite alimetry, so i guess its all related.

    More like this year's straight-to-video shark movie Megalodon [imdb.com]:


    Oil...the quest for it is unrelenting. The search for new reserves of the 'black gold' never-ends and leading the search is Nexecon Petroleum and its flagship-the largest drilling and refining platform ever constructed-'Colossus" located in the freezing North Atlantic waters off the coast of Greenland.

    'Colossus' will drill deeper than any rig ever has, a fact that gratifies Nexecon CEO, Peter Brazier, but that has geologists the world over up in arms, concerned that delicate ocean floor fault lines could be disturbed with catastrophic effects. Skeptical news reporter Christen Giddings and her cameraman Jake Thompson are invited by Braziera to document the safety of 'Colossus.'

    The powerful drill tears through the seabed, striking a rich oil deposit. As the drill penetrates further, it ruptures a fissure that reveals a second 'mirror' ocean that has existed beneath ours for millions of years. An ocean teeming with prehistoric life. As the choking oil posions the water, the frenzied creatures swarm for the surface.

    Colossus buckles under the onslaught. Brazier, Christen, and a team of engineers descend in Colossus' glass elevator to assess the damage and come face to face with the most powerful oceanic predator that ever lived. Carcharodon Megalodon. The giant ancestor of the Great White Shark. This eleven-ton 'killing machine' quickly stakes its territory in the waters surrounding Colossus with disasterous and horrific consequences, destroying and devouring anything in its path.

    Now fate will pull them together as they wager their changes of survival against the most fearsome creature that ever dominated the ocean, and pit the technology and machinery of man against beast. Megalodon...sixty feet of prehistoric terror.

    by dankelley ( 573611 ) on Saturday June 26, 2004 @09:53AM (#9537017)
    One of the big worries about the Arctic is climate change. Much of the ecosystem relies on the presence of ice, and this ice seems to be disappearing. See fig 16.3 of the IPCC report [grida.no] for a timeseries going back 100 years. In the past few decades we have had adequate measurements of wate temperature in the Actic, and it appears to be rising; see the diagrams in a recent essay [noaa.gov] at the NOAA site, for example.

    As ice changes, so does the ecosystem. Polar bears cannot walk on water, for example.

    There are also global consequence of Arctic change that worry climate scientists. For one thing, there is a nonlinear feedback loop since ice has a high albedo. Thus, ice reflects solar radiation back to space, which keeps the system cool. But water has a much lower albedo than ice. This yields a nonlinear feedback loop. Melting ice creates open water, which absorbs more heat, which melts more ice. There was a time when USSR scientists suggested we could open up a northwest passage through the Arctic simply by painting the ice black, setting this feedback loop into action. Of course, if the ice melts, navigation will be easier through the Arctic. Traffic may avoid Panama and go through a more direct route. Part of this traffic could be oil tankers, which can run aground, causing great damage to a system already damaged by the climate change.

    • As ice changes, so does the ecosystem. Polar bears cannot walk on water, for example.
