Images of Ocean Floor Show Effects of Tsunami 357

Posted by Zonk from the chaos-theory-in-action dept.
Iphtashu Fitz writes "This week the UK's Royal Navy presented images taken by the survey ship HMS Scott of the damage to the floor of the Indian Ocean that triggered the tsunami two months ago. The Scott has a high-resolution multi-beam sonar that let it generate highly detailed images of the sea floor, some 200m to 5000m below sea level. An image showing the scale of the damage, and the full presentation made by the Commanding Officer of HMS Scott (38MB PowerPoint) are available. The presentation contains a number of images that have more detail than those available on the websites."

    BZZZT! The surface of the earth cannot be damaged. Changed, yes, but not damaged. Unless you're suggesting that we need to get back to Pangaea somehow.

    Look, there are natural tectonic processes that have been going on for as long as the earth existed. Volcanoes and earthquakes are CONSTANTLY reshaping the surface of the earth. THIS IS NOT DAMAGE. This is normal behavior for the ecosystem.

    Next we'll be hearing that the predator/prey relationship needs to be banned because it damages animal populations, or that animals need to poop more because the coprophilic bacterial populations are abnormally low.
    • Just because it's damaged doesn't mean it's bad. I damage a golf ball every time I strike it with a club. Eventually that ball must be replaced. It's perfectly normal, but it's damage. I didn't see anywhere in the article (And not just because it was slashdotted before I got there) where they were talking about banning earthquakes.

      Earthquakes cause damage. That's all there is to it.
    • Correct- the surface of the Earth has not been damaged. However, a small subsection of the surface of the Earth has been damaged. If, somehow, the tectonic plates carrying North America and Siberia were induced to move towards each other, the pacific ocean would be completely obliterated (and the surface of the earth still wouldn't be damaged).
      • BZZZT! Wrong answer. It is ALTERED, but not DAMAGED. "Damage" implies some sort of breakage, or loss of function, or abnormal behavior. Plate tectonics are none of that.

        When an iceberg calves, the glacier is not damaged. If the glacier melts, the glacier isn't damaged. Gone, yes, but not damaged. When an avalanch occurs, the snowfield is not damaged. When it rains, the clouds are not damaged. When a river floods and changes course, its floodplain is not damaged. All of these are nature's normal behavior. O

      Dude, calm down. Maybe the choice of words wasn't the most scientific, but if you see the effects of a big earthquake or volcano, it's kind of hard not to see it as damage, whether it is a normal occurance or not. I remember as a kid when Mt. St. Helens blew and completely devastated the surroundings. Sure, over time it will be just a little bump in history, but for the people affected, it's damage. Is this a reason to start jumping up and down and calling people ignorant?
      • Sorry. You had me until your last sentence. "Damage to the floor of the Indian Ocean" is a COMPLETELY different concept from "damage to human beings." I would argue that earthquakes CAN NOT cause the former, but they DO cause the latter quite frequently.

        Bravo, sir! You have amused me, as well as intelligently disagreeing with me. Truly is it said, "If I can't have a good friend, at least let me have a worthy opponent."

        Now, to refute your refutation.

        The car is a human artifact. It exists solely because human beings created it. It has a purpose to its existence. When any circumstance makes it less fit for its purpose, we call the result "damage." I don't think you can disagree that this is the generally accepted view of things.

        On the other hand, if I take my dented car to an auto-body shop, an old-school one where they still fix things instead of ordering replacement panels, I will find that they dent the car further, and drill holes in it, and scrape it with abrasives. Are these damage? I would suggest not, since these, in the end, make the car more fit for its intended purpose.

        (I think I have here the beginnings of a Theory of Intelligent Design for cars.)

        "Damage to an ecosystem" must not be semantically entwined with "changes to the ecosystem." Human ecological catastrophes must not be confused with natural ecological changes. Otherwise you will get anti-environmentalists excusing human damage to ecosystems as one more example of nature red in claw and fang, humans as the ultimate predator and shaper of their environments. Beaver dams changing the course of a stream? Normal. Humans building a hydroelectric dam that floods hundreds of square miles? Hey, why not? Beavers do it, right?

        Anyway - that's my point (one of them, at least). Start calling natural events damaging...and you've handed the anti-environmentalists a get-out-of-jail-free card. "Sure, we've eradicated 43 species this year - but giant meteors from space have historically done 1,000 times more damage! So it's OK!"

      Come on now, you're not even attempting to understand what they are talking about. I don't know how this was modded insightful, but it is damage my friend. Animals died, habitats were destroyed, plant life uprooted/moved/destroyed, rare/endangered species killed (not that I know for a fact, can't see the webpage). This is damage. It doesn't matter that these animals would die eventually anyway, it doesn't matter that in 200,000 years that piece of ocean floor won't exist anymore.

      Your cocky presumptiousness does not bely intelligence, it belies a refusal to understand something. Damaged, changed, modified, whatever it all means the same thing. And gee, the two "ridiculous" examples you list probably already happen somewhere in the world! People hunt to keep animal populations down (those bastard deer come to mind); I'm sure somewhere in the world predators are being kept away from herbavors to "protect" the herbavors from being "damaged". Hmm, maybe we should just ban the word "damaged", because obviously every thing that happens in the universe is due to nature. Therefore everything that happens would have happened eventually anyway, and it can not possibly be considered damage because it is "all in the natural order of things."

      Why don't you use your self-proclaimed knowledge for something useful, like understanding that words can mean multiple things and not everything people write about is a semantic argument?

      • Your first logical error occurs in the first word of your third sentenct. "The floor of the Indian Ocean" is not "Animals, habitats, and plants."

    A 40 MB file on the front page. Way to go douchebags, thanks for taking our server out. Here's the text of the article:

    The Royal Navy's survey ship HMS Scott has collected unique images of the Indian Ocean seabed in the vicinity of the devastating tsunami earthquake epicentre.

    The work, announced last month by the Ministry of Defence, is being carried out in order to further the understanding of earthquakes and assist prediction of such events in the future. It will be of considerable benefit to the Asia region as a whole and potentially give a global perspective.

    HMS Scott's tasking is a non-military role that will provide bathymetric ( measuring the depth of water ) and geological assessment of the Asian earthquake epicentre and extended fracture zone. To assist with this, scientists from the Southampton Oceanography Centre and the British Geological Survey have embarked in the ship.

    The depth of water in the vicinity of the epicentre varies between 200m to 5000m which is well within HMS Scott's capability using her high-resolution multi-beam sonar.

    The epicentre lies within the Indonesian Exclusive Economic Zone, and the survey itself follows discussions with the Indonesian Government about HMS Scott's potential value in furthering the understanding of the earthquake and future risk prediction. The survey falls under the definition of Marine Scientific Research under United Nations Convention on Law of the Sea (UNCLOS).

    Survey imagesHMS Scott's survey will provide the 'base map' for future extensive research into the process of how earthquakes work; this is a crucial moment to conduct such research.

    While HMS Scott is not directly involved in the humanitarian relief effort, her survey work in the vicinity of the epicentre is of significance to the scientific community in furthering the understanding of the tsunami.

    HMS Scott deployed from the UK in November 2004 in order to undertake a programme of work in the North Atlantic, Arabian Sea and Indian Ocean and is scheduled to return to the UK in June 2005.
