Underwater volcanic range discovered off coast of Norway

Underwater volcanic range discovered off coast of Norway

2,200 F (1200° C) magma pouring into the seas from hundreds of submarine volcanoes – and we wonder why the seas are warming.


Researchers at the University of Bergen (UiB) have found a 932-mile (1,500-km) volcanic mountain chain hidden off the coast of Svalbard, which could soon break the surface to form a new island chain.

The range extends from Jan Mayen island in the Greenland Sea to the Fram Strait between Svalbard and Greenland.

“We have discovered five new vent fields in Norwegian national waters between Jan Mayen island and Loki’s Castle,” Rolf Birger Pedersen, the professor leading the research, told The Local. “The vent fields were discovered during a cruise with RV GO Sars in July this summer.

The last volcano was found a few weeks ago and is just 20 meters below sea level,  said Pedersen, professor at the Centre for Geobiology (UiB).

“We have found volcanoes at such a shallow level and they could break the surface at any time and form a new island group,” said Pedersen.

“We have long known that Iceland has both volcanic activity and hot springs, but we thought that we did not have anything like that in Norway. But we do, it was only under water,” he added.

Pedersen made his name in 2008 when he discovered the underwater volcanic range Loki’s Castle. The new discovery comprises hundreds more volcanoes, some just 20m below the surface.

Just for the record, I’ve been talking about underwater volcanoes for years. In fact, there’s an entire chapter in “Not by Fire but by Ice” (entitled “Fish Stew”) that discusses the importance of underwater volcanoes, and how they’re heating the seas.

“The Norwegian version of this text speaks about the activity of those volcanoes and 1200° C magma,” says Chris. “I don’t know why that information isn’t included in the English version.”

“Just as you discussed in your book,” says David. “This article neglects, of course, the possibilities that volcanoes (rather than human heating) may be “melting the Arctic.”

“Definitely a reason for altered currents and some warm seas,” says Laurel.

“So the global warming in the arctic is so severe that it is even causing the ocean floor to boil up and ready to boil over the surface at any time!” says Ed MacAulay.

“Imagine how much heat is being put into the Arctic ice from prevailing currents,” says Peter. “How much might this be causing ocean warming in the area?”

    Good Question!, I saw this article too, and got no indication of whether any or how many of these underwater volcanoes were active.

    • This is very important and could be a significant factor besides solar radiations and the usual ocean oscillations (PDO, AMO and ENSO).
      Of course, there is no “CO2” or “humans” involved in any of this.

  2. Underwater volcanoes could be the only cause of positive temperature anomaly in the northern seas. This discovery confirms a theory of mine.

  3. As the article states ‘hundreds’ and in such a small area, which suggests a gross underestimate of the guesstimate of submarine volcanoes in the rest of the world’s oceans: perhaps many more than two million.

  4. Guess WE all notice that this doesnt rate a whisper by Msm Shills.
    sure makes it hard to say the “missing surface heat” is surface heat miraculously transferred by some arcane means to the -200 feet level of the oceans..roflmao!

  5. It would be interesting to see if there are Argo Buoys submerging near this range and if so, are they being affected.

  6. Are the oceans really warming? Further, are these newly discovered volcanos throughout the world’s oceans new volcanos? Hasn’t this volcanic activity gone on for millions, tens of millions, hundreds of millions of years?

    If the volcanos in the oceans were really warming the ocean, after a few tens of millions of years one would think that they would have boiled all the water out and we would have a thick, wet, cloud covering all around the globe.

    Water is very dense and there is an incredible amount of cubic miles of it in the oceans. And still the oceans are very cold in the deepest parts. The incredible amount of water in the oceans would take a mind boggling amount of heat to warm them up. More, I say, than the natural, ongoing volcanic activity on the ocean floor we now know of but which has had to have been going on since the oceans were first formed.

    • Yes. So dense at extreme depths that it can be below freezing and remain liquid!
      Mind boggling indeed!

    • The big question is, how many of these volcanoes are active and at what VEI level?
      A little smoking here and there would make no difference.

  7. Interesting…
    That could explain why some seas are warming. But I wonder if they will start to cool again? And I wonder if this explains the “record” warming of the North Pole?

  8. I have a problem with the report of volcanic peaks being found as close to the surface as 20 meters unless they are talking about the surface of the ocean floor between 1 to 2 kilometers below the surface of the ocean. Google earth indicates that all geophysical features are in very deep water.
    What might be of interest is the possible developement of a subduction zone off shore from Lisbon Portugul. If and when that gets going good and proper things will really get interesting in western europe and the mid atlantic ridge. With a working subduction zone the spreading action at the mid atlantic ridge will eventually increase. It will allow europe to either slide westwards and or allow the eastern atlantic to move and allow more volcanic activity at the mid atlantic ridge. Warmer fish stew anyone? If europe starts to slide westwards that will allow spreading action elsewhere like the Rio Grand rift fault, death valley, the New Madrid fracture zone and the San Andeas Fault system. Also the mid atlantic ridge comes ashore in eastern Russia and extends south to the Fossa Magna rift valley in Japan south of Tokyo. If that starts to spread does that mean a repeat of the Siberian traps event? The lack of an active subduction zone either side of the atlantic more or less stabilizes the world as we know it. When that changes interesting times are indeed possible.
