Volcanic eruptions reshape Arctic ocean floor: study

Wed Jun 25

PARIS (AFP) - Recent massive volcanoes have risen from the ocean floor deep under the Arctic ice cap, spewing plumes of fragmented magma into the sea, scientists who filmed the aftermath reported Wednesday.

The eruptions — as big as the one that buried Pompei — took place in 1999 along the Gakkel Ridge, an underwater mountain chain snaking 1,800 kilometres (1,100 miles) from the northern tip of Greenland to Siberia.

Scientists suspected even at the time that a simultaneous series of earthquakes were linked to these volcanic spasms.

But when a team led of scientists led by Robert Sohn of the Woods Hole Oceanographic Institution in Massachusetts finally got a first-ever glimpse of the ocean floor 4,000 meters (13,000 feet) beneath the Arctic pack ice, they were astonished.

What they saw was unmistakable evidence of explosive eruptions rather than the gradual secretion of lava bubbling up from Earth’s mantle onto the ocean floor

The mid-ocean ridge runs 84,000 kilometres (52,000 miles) beneath all the world’s major seas except the Southern Ocean, and marks the boundary between many of the tectonic plates that make up the surface of the Earth.

When continental plates collide into each other, they can thrust up mountain ranges such as the Himalayas.

But along most of the mid-ocean ridge — including the Gakkal Ridge — the plates are pulling apart, allowing molten magna and gases trapped beneath the crust to escape

Both sonar and visual images showed an ocean valley filled with flat-topped volcanos up to two kilometres (1.2 miles) wide and several hundred metres high.

Er, is it not possible that these volcanic eruptions — going back to at least 1999 — may have played a part in whatever melting there has been of the Greenland and Arctic ice sheets?

If there has even been any.

For according to the global warming cultists scientists at NOAA’s Geophysical Fluid Dynamics Laboratory, the amount in ice began to decline precipitously in around 1999, which is when these volcanoes began their eruption.

But isn’t it funny how not one word about the purported simultaneous decline in arctic ice was ever mentioned in the original article?

Why do you suppose that is?

    SG, this is preposterous and I demand you take this anti-global warming/cooling/methane gas spewing news off the site (cakcle cackle).

  2. Lurkin_no_mo

    If this is caused by active volcanos then it is still global warming! Or at least far north warming. But I’m pretty sure, although I’m certain the left will disagree, that man is not causing this.
    Could be that all the pollution we dump in the ocean floated up north and drifted down into the volcanos, and this clogged them up, and the only way the volcanos could clear themselves out was to erupt.
    I know, don’t give the left ideas. But then, my theory is as based in fact as theirs is about global warming.

  3. Diane

    If I remember correctly, volcanoes also release significant amounts of carbon into the environment. Does this mean we have to fine God for violating the Kyoto accords?

  4. notsoyoungjim

    Possible lefty explanations:

    1) Global warming has melted the arctic ice enough so that the seeping magma has become a torrential river of carbonated death due to the lifting of the ice (which was acting like a bottle cap on the volcanic ridge).

    2) Excess carbon has dropped from the atmosphere into the arctic seas which feeds the magma on the ridge like an enormous alka-seltzer making the magma hotter, melting the ice cap in concert with global warming.

    3) Drilling all that is left of peak oil is causing the ridge to widen as the earth’s crust shrinks like a prune without the fluid oil beneath it.

    4) Gaia is hacked off (cuz of all of the above, natch) and is releasing the dogs of magma which will grow like a giant earthy zit on the bottom of the ocean.

    You heard it here first.

  5. Cincinnatus

    All of the ocean basin floors have a volcanic origin and have been active for at least the last few hundred million years. Subaqueous volcanoes do not generate enough heat to melt the massive volumes of ice that make up Earth’s polar caps. If the permanent caps are shrinking (and the evidence for this is uncertain), it’s probably NOT caused by ocean floor volcanic eruptions. And only the north pole is over an ocean basin; Antarctica is a continental land mass.

    There’s more on this story at Science Daily:

    Fire Under Arctic Ice: Volcanoes Have Been Blowing Their Tops In The Deep Ocean

    … “These are the first pyroclastic deposits we’ve ever found in such deep water, at oppressive pressures that inhibit the formation of steam, and many people thought this was not possible,” said WHOI geophysicist Rob Reves-Sohn, lead author and chief scientist for the Arctic Gakkel Vents Expedition (AGAVE) of July 2007. “This means that a tremendous blast of CO2 was released into the water column during the explosive eruption.” …

    To date, there have been scattered signs of pyroclastic volcanism in the sea, mostly in shallower water depths. Samples of sediment and rock collected on other expeditions have hinted at the possibilities at depths down to 3,000 meters, but the likelihood of explosive eruptions at greater depths seemed slim.

    One reason is the tremendous pressure exerted by the weight of seawater, known as hydrostatic pressure. More importantly, it is very difficult to build up the amount of steam and carbon dioxide gas in the magma that would be required to explode a mass of rock up into the water column. (Far less energy is needed to do so in air.) In fact, the buildup of CO2 in magma in the sea crust would have to be ten times higher than anyone has ever observed in seafloor samples.

    The findings from the Gakkel Ridge expedition appear to show that deep-sea pyroclastic eruptions can and do happen. “The circulation and plumbing of the Gakkel Ridge might be different,” said Reves-Sohn. “There must be a lot more volatiles in the system than we thought.” The research team hypothesizes that excess gas may be building up like foam or froth near the ceiling of the magma chambers beneath the crust, waiting to pop like champagne beneath a cork.

    “Are pyroclastic eruptions more common than we thought, or is there something special about the conditions along the Gakkel Ridge?” said Reves-Sohn. “That is our next question.”

    “These are the first pyroclastic deposits we’ve ever found in such deep water, at oppressive pressures that inhibit the formation of steam, and many people thought this was not possible,”

    Thank you, SG. Fascinating. But I thought we already knew everything there was to know about geology and climatology. I mean, how could we be absolutely certain that the climate is changing and people are responsible if we couldn’t eliminate or discount every other possible cause? I am so confused now…

  8. Helena

    “And only the north pole is over an ocean basin; Antarctica is a continental land mass.”

    Which would argue that while the Arctic ice might be affected by volcanos, the Antarctic ice would not. In fact I read - somewhere - that the Antarctic ice was increasing. It was mentioned as a potential tragedy for penguins, as I recall, which would now have to travel longer distances to open water and might be enough of a distance to impact the parents switching off egg/chick tending. Maybe the amount of ice worldwide is maintaining a constant level.

    Of course, Diane, I also read that the Van Allen belts were reversing their polarity - which apparently they do now and then - and that this might affect all sorts of things. Too little information, too many theories.

    “Does it really bother you?”

    On a scale of 1 to 10, where 10 is nuclear holocaust — it’s only about a 7.

    My head, sir, is both bloody and bowed. I should’a known better.
    I’ll just drag my sorry ass off to the Conservative Canadians’ Graveyard (located on the Otaskwin-Attiwaspikat River) and let the VRWC -Canadian Chapter (located under the Wal-mart in Flin Flon, Manitoba) select a new token Canadian for this site.
    You’ll probably get someone dour and humourless the next time around, but, hey, at least his question marks won’t have a space in front of them.
    He probably won’t understand the subtle nuances of dealing with Americans the way I do (never mention who really won the War of 1812, never mention who invented the Garand rifle and never mention who holds the world record for sniping) but his paragraph spacing will be bang-on.
    I’ll just lie there and rot. Probably get eaten by scavengers and big bugs while you adjust to your new Canuck and wish I was still around (unless, of course, you get a hot chick -I heard there’s one in Calgary).
    But that’s OK (sniffle). I understand…

    Damn, I wonder if SG could survive the abysmal grammar and punctuation used by todays untaught and uneducated but chock full of self esteem kids ?

    DW,

    Being that you are a Canadian(or is that Canadien? :P), you should be used to it, right? I mean, with that whole ‘almost-parity-of-the-dollar’ thing, your self-esteem has got to suffer. And, I’ve been to Calgary - all the hot chicks left for Wyoming… Edmonton, on the otherhand…

    (Not to attempt to steer the conversation back to the topic, but…) Since Canada has laid claim to the ocean floor in the Arctic, I fully expect Canada to own up to the problem and find some fix this global-warming-causing event.

    Exclusive: No ice at the North Pole

    Polar scientists reveal dramatic new evidence of climate change

    By Steve Connor, Science Editor
    Friday, 27 June 2008

    It seems unthinkable, but for the first time in human history, ice is on course to disappear entirely from the North Pole this year.

    The disappearance of the Arctic sea ice, making it possible to reach the Pole sailing in a boat through open water, would be one of the most dramatic – and worrying – examples of the impact of global warming on the planet. Scientists say the ice at 90 degrees north may well have melted away by the summer. . . .

    They have a nifty graph showing how the ice melts all the way thru July (which is only a few days away) so I’m guessing that we’ll know if they’re right in a month or so. I find their claim of the “first time in human history” suspect–so the rest of the claims (50/50 chance) sound rather bunko also.

    Call me a pyroclast if you want but I’m going with the underwater volcanoes as the culprit–these mopes (and Drudge) still haven’t got the memo.

    Meanwhile here is a pic of the ice yesterday as opposed to 10 years ago yesterday:

    I mean, with that whole ‘almost-parity-of-the-dollar’ thing,

    And, I’ve been to Calgary - all the hot chicks left for Wyoming… Edmonton, on the otherhand…
    Edmonton is known as Redmonton by proper Calgarians. With good reason. All the good looking chicks there are probably guys in drag.
    Can you sponsor me for immigration to Wyoming?

    I fully expect Canada to own up to the problem and find some fix this global-warming-causing event.
    We are currently working on our submarine. Bear with us…

    Notsoyoungjim: Quite often you will find the press yipping and yapping about the ice in the North-west Passage being gone for the first time in history. It’s a load of crap. Vessels have been transiting that passage since Peary did it in 1903-1906 (yes, it took him a couple of years, but bear in mind that he didn’t have a chart -so he made the first one).

    I have a hunting trip planned to North Dakota in Oct. I’ll make sure that I walk up to the border marker, gun in hand, and hurl demands in the general direction of Canada requiring the cap of millions of tons of greenhouse gases venting from Canadian lands into pristine seawater.

    If I weren’t shooting pheasant, I am sure I could get Greenpeace to join me in this protest. I wonder if Kofi is available…

  30. Alan Sullivan

    This post got linked at Icecap, which is how I found my way over here. I have commented on this topic twice at my own site. I’ll copy over two paragraphs:

    “Icecap has succumbed to nonsense about undersea volcanoes in the Arctic. Scientific illiteracy knows no ideological bounds. Icecap has foolishly cited Thomas Lifson, off the reservation at American Thinker. Lifson thinks that global warming disclaimers should have accompanied the publication of a discovery about a 1999 eruption.

    “You may remember the Antarctic volcano recently studied for possible “lubrication” of an ice sheet. This is something that could actually happen, because the heat plume is in direct contact with rigid, insulating ice, and the effect is essentially local. But an ocean is fluid, not solid, and its thermal inertia is absolutely immense. The notion that one or several eruptions could affect the temperature of the whole ocean is ludicrous.”

    I write about climate often. I am a skeptic, especially about AGW, which is unproven and probably unprovable. But I have been dismayed by how many skeptics have betrayed their own ignorance over this undersea volcano story.

  31. notsoyoungjim

    In response to Mr. Sullivan above:

    The IBD has published the following with regard to the notion of volcanic activities causing artic polar melt:

    “Is it possible that it these eruptions, part of an “ongoing process,” have played a part in whatever melting there has been of the Greenland and Arctic ice sheets?

    Scientists at NOAA’s Geophysical Fluid Dynamics Laboratory have put together a chart showing Arctic ice relatively stable until a precipitous decline began in 1999 — the very year the Arctic eruptions started.

    Icebergs breaking away and polar bears supposedly drowning are good theater, but they do not reflect reality. In April, the World Wildlife Fund (WWF) published a study, based on last September’s data, showing Arctic ice has shrunk from 13 million square kilometers to just 3 million.

    What the WWF didn’t mention was that by March of this year the Arctic ice had recovered to 14 million square kilometers and that ice-cover around the Bering Strait and Alaska was at its highest level ever recorded. Ice freezes. Ice melts. That’s what ice does.”

    http://tinyurl.com/6zw6bp

    Assuming your point that the volcanic activity causing the warming is nonsense, what have you to say to the WWF’s playing fast and loose with the facts in ignoring the expansion of the polar ice sheet this year while promoting the claim that that same ice sheet will likely disappear this summer? (A condition the greenies contend is happening for the first time this year.)

    Quoting from that same IBD editorial “In August 2000 the New York Times ran a piece claiming the pole was free of ice for the first time in 50 million years, long before SUVs roamed Earth. As earth scientist Patrick Michaels noted, “It was retracted three weeks later as a barrage of scientists protested that open water is common at or near the pole at the end of summer.”"

    Oddly you label this pyroclastic activity notion as nonsense, while completely ignoring the straw man provided by greenies that prompted this theory in the first place.

    Furthermore who’s to say it’s the thermal activity that’s melting the sheet and not the CO2 released from the volcanic eruptions? Again it’s the greenies who wail that humans are causing the increased carbon, yet to my memory they’ve never acknowleged the possible natural causes of CO2 increase due to volcanic activity. From the editorial: “Robert Sohn, WHOI geophysicist, lead author and chief scientist of the July 27, 2007, Arctic Gakkel Vents Expedition, estimates that exploding mixtures of lava and gas were expelled at speeds of more than 500 meters a second.

    Sohn says the large volumes of CO2 gas that belched out of the undersea volcanoes likely contributed to rising concentrations of greenhouse gases in the atmosphere.”

    You claim to be an AGW skeptic which is “probably unprovable.” More likely, you are an AGW apologist having accepted the dogma while acting in concert with the greenies to label the skeptical critics as ignorant.
