Came from an underwater volcano.
The New Zealand Navy announced today that they have found a patch of floating volcanic pumice from an underwater volcano floating about 600 miles off the shore of New Zealand.

“The rock looked to be sitting two foot (half a meter) 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,” said Lieutenant Tim Oscar aboard the ship the HMNZS Canterbury.

Scientists aboard the ship said the white pumice – which covers 10,000 square miles ( 26,000 sq km) – probably came from an underwater volcano called Monowai, which has been active recently, but that it was unrelated to other increased volcanic activity in New Zealand this week.

I wonder what is heating our seas? And I wonder how many fish will dies as a result of this eruption?

    10,000 square miles of white pummice, not just looking like an ice sheet, but also reflecting sunlight just like ice and snow does ? What effect is that 10,000 square miles of floating pummice going to have on the climate ? I am not qualified to give definitive mathematical answers to the questions. But as a rough guess I suspect that 10,000 square miles of such reflective material is certainly going to effect the climate.

      Neil, 10,000 square miles is 100 miles squared, only a tiny dot on the surface of our planet. We get a lot more cooling effect from the volcanic ash and dust thrown up by a land based volcano.

    • If this mass gets into shallow waters, it could form a new land mass! Think about that!

    Isn’t it amazing how a group of different volcanoes, all in the same area, seem to become active at about the same time but we are assured that the activities are “unrelated.” Must be that the activity, somehow, doesn’t fit their preferred computer simulation.

    And has anyone else noticed how many scientific dilemmas lately have been “solved” by computer simulations? Very similar, I suspect to the climate computer simulations? You can approximate something by computer simulation, but unless you actually know ALL of the factors that affect the process you are attempting to “simulate,” you are, in fact at best, only approximating the process, not duplicating it. How far science has wandered from what it is – an approximation of the universe as we understand it, to the precise model that has been determined by “simulation” and mathematical manipulation.

  3. TomO says:

    By the way, if that entire 10,000 sq miles were actually 2 feet deep in the stuff, that is a very large volume of pumice. Not sure how many cubic yards of real magma it would be, but that figures to be quite a bit more than a cubic mile of pumice.

    • Marcus says:

      309,760,000 cubic yards of pumice.
      Of course, if the pumice was only the size of a pea (1/4 inch) then, it would be about 645,333 cubic yards. That’s still abunch of pumice! How much ice could that melt?

  4. Jbird says:

    10,000 square miles? I doubt this came from a single vent. More likely a number of vents or a large fissure on the ocean bottom. It needs to be studied.

  5. I wonder how thick a layer is under the water…We should stick a flag in it and claim it !!

  6. Caroline in West Virginia says:

    Just consider that the melting point of pumice is around 1700 F and that this stuff WAS molten when released. 10,000 square miles of the stuff? That is an absolutely ENORMOUS amount of heat. Now think about the effect of a volcano underneath the Arctic or Antarctic ice. Basalt lava is capable of melting about ten times its own volume of ice. Impressive, hey!

  7. Frank says:

    did anyone here the figure 10,000 square miles… my god… that has to have an extreme affect on our already fragile climate on the verge of an ice age. I have said we are waiting for triggers to fire us into the next ice age. This could be one of them.

  8. Steven Rowlandson says:

    Would ground up pumice be usefull for containment of nuclear fuel pellets and corium? Pumice has alot of silica which could melt and encapsulate hot radioactive material and seal it into a rock matrix
    for easier storage and maybe handling.

    • AndrewS says:

      so does sand(have a lot of silica) but it wouldn’t shield from radiation…
      I’ve mused that subduction zones would
      be a good disposal site for nuclear and toxic materials, but secure delivery to said zones might be a problem. And the recycle rate is so slowwww.

      • Steven Rowlandson says:

        Another thought that occurred to me is that if nuclear fuel and waste could be transported to the Erta Alle volcano in the danikil depression it could be put into a pool of magma for permanent disposal.
        The radioactive materials would be part of basaltic magma and ultimatelt diluted and incorperated in an igneous rock matrix.

    10,000 square miles is bigger than the state of new jersey.
    http://www.enchantedlearning.com/usa/states/newjersey/
    That is pretty darn big.

  10. twawki says:

    Scientists have said?

    The Monowai seamount, which lies at the intersection of the Pacific and Indo-Australian tectonic plates at the Tonga-Kermadec subduction zone, underwent one of the fastest episodes of volcano growth documented on Earth.

    It added about 8.75 million cubic metres of rock to its summit – a volume equal to 3500 Olympic-size swimming pools – in just five days.

  11. BobbyR says:

    To put it in perspective the 10,000 square miles is 6,400,000 acres.

    The island of Sicily in the Mediterranean Sea is only 6,352,576 acres.

    • Postman1 says:

      The Earth’s surface is 57.3 Million Square miles. This is big in human perspective, but small to the planet.

  12. blair mckerley says:

    Why has no one made mention about the fact they say it was FLOATING about half a meter above the waves?????????FUCKING FLOATING.!!!!!!!!!

  13. laurel says:

    lookinmg at USGS last week or so theres been some largeish quakes mid ocean down sth. this could have come from anywhere, Goog earth may be the best way to be spotting the sudden appearance if anyone knows how?
    wouldnt be stressing, its normal natural and it will break up with wind/wave actions and end up on beaches all over the place.
    it wouldnt have to be a huge vent either, its underpressure and the bubbles form as it rises and expands. like that sprayfoam filler:-) little can=big mass of goop.

  14. George says:

    From a New Zealand report……’Cornel de Ronde, principal scientist of New Zealand’s Institute of Geological and Nuclear Sciences, told Radio New Zealand the source of the pumice had been identified in cooperation with French researchers in Tahiti who monitor earthquakes in the southwest Pacific. “When they looked at their physical records they saw that on July 17th and 18th, there were some 157 earthquakes of magnitudes between 3.0 and 4.8,” he said. De Ronde said they occurred near the time of the first sighting of the pumice ‘raft.’ When the institute looked at its database, it found the Havre volcano, which it had previously surveyed. It was a caldera volcano, like White Island off the west coast of New Zealand’s North Island, which erupted last week, but the Havre was not thought to have erupted before.’

  15. Craig Read says:

    That co2 sure is one potent chemical/toxin. Now it causes sea level volcanic eruptions of enormous heat and size…..of course such events in the 4 billion year history of the goddess Gaia have NEVER occurred before….only with man and his immoral carbon spewing civilization do we witness such natural destruction….blah blah duh duh….leftardology is one sad sorry mindless bunch of puerile crap.
