Huge Pumice Rock 'Island' Seen Floating In South Pacific 104

    If it's like previous pumice rafts [wikipedia.org], it's more like a large area of debris than a big island. Here's a random photo [visualphotos.com] showing a boat plowing a path through one made up of smaller pieces. Not really the kind of thing you can walk around on, though the description of this one having an edge like an ice-shelf makes it sound like it may have larger rocks in it. Here [nasa.gov] is a NASA satellite photo of a 2006 occurrence with a more obvious origin (it's adjacent to an erupting volcano).

      If you click through to TFA's TFA [theaustralian.com.au], you'll see they properly used the term "raft" unlike MSN. They also mentioned that their vessel plowed right through it, even though "The rock appeared to be sitting above the surface of the waves and when lit up looked like the edge of an ice shelf."

      For further terminology bending, the Daily Mail calls it a rock ice-shelf [dailymail.co.uk]. They also have a pic of it that looks more frothy than island or ice-shelf like.

        I like the part where they include a bunch of gratuitous photos of actual ice shelves.

      • Ah bummer. The article made it sound like this was a giant piece of rock that you could walk on. That would be nifty.
        • With a pair of large skis - water skis perhaps - it's not entirely impossible.

        They then go on to blame it on illegal immigrants and ask if it is likely to affect house prices.

        However, they haven't yet determined whether pumice is the latest miracle food or whether it's this week's innocuous substance that has been found to cause cancer in those gullible enough to believe scaremongering journalism.

    • A quote from the dailymail article:

      'The rock looked to be sitting two foot (half a metre) above the surface of the waves and lit up a brilliant while colour in the spotlight. It looked exactly like the edge of an ice shelf.'

      Sooo, maybe something big!

    • No, not an island. It's a flotation device.

    • Why yes, I have seen a satellite photo of Late.

    • Maybe for small boats it's OK to plow through it, but with larger boats and ships I would think it is not a good idea. They have a tonne of water inlets from below the water line for things like engine cooling/heat exchangers, and flushing out sewage, bilge pumps, etc. That pumice can thoroughly fuck up a pump. Or clog a heat exchanger. That could shut down one of those massive diesel engines right quick. It could also mean having to reapply antifouling paint on some vessels depending on how far they had to
    • Aww crap! And I've already booked the cruise... The travel agent said I could walk on the island first in the morning, and then the ship's crew would turn it over and I could walk on the other side in the evening.

  • The pumice in these islands was created by underwater volcanos. How much heat are these conspirators against humanity putting into our oceans? Maybe THEY are to blame for the melting ice caps?

    • Not a chance. The heat receive from the Sun and retained by the Earth is several orders of magnitude greater than all volcanoes put together. Volcanoes are insignificant in that regard.

        Not sure where you got that price from.

        USGS Minerals Industry Summary - Pumice [usgs.gov]. That's the bulk price.

        There are "Trash Hunter [aquarius-systems.com] boats that could pick up pumice, but they're not intended for remote open-ocean operations. To collect this stuff, it would take booms and ocean-going tugs or fishing boats to concentrate the floating pumice, a collection vessel to pull it out of the water and screen it, and a bulk freighter to haul it to some customer. It's like cleaning up an oil spill, except that it's a solid. It might be desirable to do this if the mess drifts to a populated area.

        Over time, wave action breaks the stuff up, opens the gas pockets that make it float, and it sinks. This takes about a year [unsw.edu.au], so it's not a long term problem. It happens now and then. Known events off Tonga in 1964 and 2002 have been studied. Long-term impact is low; it's hard to tell, a few years later, that it ever happened.

    I have many years ago seen beaches in New Zealand composed entirely of pumice. I saw them north of Gisborne on the North Island and pumice was quite literally the only thing you could see on the beach and it went at least as deep as my hand. On another small beach nearby the surface was covered entirely by pieces of abalone shell - an ancient Maori midden beach I assume but those beaches are all deserted and there's no-one around to ask.

  • Quick - something from the earth is oozing out and polluting the ocean - we must find a big corporation to blame. We must mobilize the media to identify the culprit and immediately begin aid operations to the millions of people and fish that will be affected by this disaster
