Expedition To Explore an Alaska-Sized Plastic "Island" 325

Posted by kdawson
from the one-hundred-megatons dept.
Peace Corps Online writes "An expedition called Project Kaisei has departed bound for the Great Pacific Garbage Patch — a huge 'island' of plastic debris in the Pacific Ocean estimated to be the size of Alaska (some estimates place it at ten times that size). The expedition will study the impact of the waste on marine life, and research methods to clean up the vast human-created mess in the Pacific. The BBC quotes Ryan Yerkey, the project's chief of operations: 'Every piece of trash that is left on a beach or ends up in our rivers or estuaries and washes out to the sea is an addition to the problem, so we need people to be the solution.' The garbage patch occupies a large and relatively stationary region of the North Pacific Ocean bound by the North Pacific Gyre, a remote area commonly referred to as the horse latitudes. The rotational pattern created by the North Pacific Gyre draws in waste material from across the North Pacific Ocean, including the coastal waters off North America and Japan. As material is captured in the currents, wind-driven surface currents gradually move floating debris toward the center, trapping it in the region. 'You are talking about quite a bit of marine debris but it's not a solid mass,' says Yerkey. 'Twenty years from now we can't be harvesting the ocean for trash. We need to get it out but we need to also have people make those changes in their lives to stop the problem from growing and hopefully reverse the course.'"

    They should collect this in barges and burn it for fuel.

      If you wanted to do that, pretty much any municipal solid waste dump would be a better bet. This is more like a gigantic patch of watery plastic soup(plus, it's in the middle of the pacific, transport costs would be irksome), dense enough to cause all kinds of trouble for aquatic fauna, tenuous enough to make collection a serious hassle.

        If it costs less than the prevailing price of crude, then it's a go - hassles be damned!

        Just look at the hassles and cost ($40/barrel) to get oil out of the oil sands in Canada. It says something about our oil supplies when paying $40/barrel to get it out of the ground is considered reasonable.

        We (humans) caused that huge mass of plastic to form in the sea by dumping our garbage in the beach or sea and in my opinion we should also try to get it out, or at least stop in from increasing in size. The problem with modern Western society is that we are not ready to start a long term project like that unless it is profitable for us in short term. And that is something that it isn't. It would be a long term money sink with no real market value, and thats why not many seems to care. In a way it feels like we are crapping our own pants because we have more important things to do than go to the toilet.

          To quote George Carlin, "...and if it's true that plastic is not degradable, well, the planet will simply incorporate plastic into a new paradigm: the earth plus plastic. The earth doesn't share our prejudice towards plastic. Plastic came out of the earth. The earth probably sees plastic as just another one of its children. Could be the only reason the earth allowed us to be spawned from it in the first place. It wanted plastic for itself. Didn't know how to make it. Needed us. Could be the answer to our age-old egocentric philosophical question, "Why are we here?" Plastic...asshole. So, the plastic is here, our job is done, we can be phased out now."
    • the images one conjures up reading the title is this big area filled with recognizable objects, however reading the wiki article states that the particles that comprise the bulk of the suspected pollution are too small and disperse to be imaged by satellite or aircraft.

      So don't let the title fool you. While there may be occasional large pollutants its not like something your bound to spot on the horizon and just sail to it. Think about it, if it were we would have seen pictures all over the news by now.

        I was also wondering about the "island" suggestion. I listened to a recent Science Friday podcast where it was explained that the average density is a thumbnail-sized piece of plastic per cubic meter. That's pretty much invisible to the eye, yet still a high density.

      What is the actual density and particle size, and how near the surface is it concentrated? Although the Pacific is enormous, it might actually be possible to do something with some kind of filter system, given long enough. After all, the East Anglian fens were drained by pumps running for over 100 years, so long term projects are not exactly unheard of. Something that stops plastic and allows through fish - there's a challenge.

        http://en.wikipedia.org/wiki/Great_Pacific_Garbage_Patch [wikipedia.org]

        Density of neustonic plastics
        In a 2001 study, researchers (including Moore) found that in certain areas of the patch, concentrations of plastic reached one million particles per square mile.[12] The study found concentrations of plastics at 3.34 pieces with a mean mass of 5.1 milligrams per square meter. In many areas of the affected region, the overall concentration of plastics was greater than the concentration of zooplankton by a factor of seven.

        he floating plastic particles resemble zooplankton, which can be inadvertently consumed by jellyfish. Many of these long-lasting plastics end up in the stomachs of marine birds and animals,[13] including sea turtles, and the Black-footed Albatross.

    • When you burn that kind of plastic, you'll get lots of dioxins produced.

      Ten times the size of Alaska???

      okay, let's run the numbers.

      Alaska's area is 663,268 sq mi.
      10x Alaska's area would be 6,632,680 sq mi.

      the USA's TOTAL area is 3,794,066 sq mi.
      Russia's TOTAL area is 6,592,800 sq mi.

      You're telling me that some people think there is a mass of garbage in the Pacific Ocean SLIGHTLY LARGER than Russia???

      I'm not saying it's not as bad as it sounds but I really doubt the numbers are right.
