91 volcanoes discovered beneath Antarctic ice

Scientists have uncovered what is now believed to be the largest volcanic region on the planet.
The discovery, which emphasizes just how much there is still to learn about Antarctica, was made following a remote survey of the region by researchers from the University of Edinburgh.

Found within an area known as the West Antarctic Rift System, the volcanoes range in height from 100m to 3,850m and bear similarities to those found in east Africa's volcanic ridge.

The survey, which involved measuring the shape of the land using ice-penetrating radar, was carried out following a suggestion by third-year university student Max Van Wyk de Vries.

"Antarctica remains among the least studied areas of the globe, and as a young scientist I was excited to learn about something new and not well understood," he said.

"After examining existing data on West Antarctica, I began discovering traces of volcanism. Naturally I looked into it further, which led to this discovery of almost 100 volcanoes under the ice sheet."

It is currently unclear whether or not the newly discovered volcanoes are still active.

Climatic warming has nothing to do with volcanic action.

I don't think that is a true statement. How much it affects global warming or global cooling is debatable, but when a volcano spews 200 million tons of carbon dioxide into the atmosphere, it is more than "nothing". Still not close to what humans are doing.

I don't think I made myself clear, my fault, what I mean is global warming does not affect volcanic action, yes volcanic eruptionscan affect climate but not vice versa as Ashetopseemed to imply.

Gotcha. I took your statement wrong. I agree with you on this. I do wonder, can a 1 mile think layer of ice "seal" a volcano from erupting?

Yes and no. If the ice overburden melts, an eruption becomes more likely because of the reduced pressure on the magma. An eruption discharges ash and CO2 into the air. In the short run, the ash restricts incoming radiation, cooling the planet, but in the long run, the ash settles out leaving CO2 which warms the planet. The Little Ice Age was caused by a combination of reduced solar input and four volcanic eruptions, ash from which cooled the planet, setting off an Arctic ice feedback loop which further cooled the planet. This was reversed when solar radiation increasedafterthe Dalton Mi... [More]

I don't think so, it would either be a massive explosive eruption, because of the built up pressure, or the magma would just flow out under the ice, melting ice until it cooled....IMHO

Got an example of that?

Weather disturbances caused by Krakatoa (1883) produced the worst winter storm in American history in 1886. Heavy snowfall in late January was added to an already-heavy snow load. In early February there followed four days of balmy weather that melted the snow into slush. Then the bottom fell out of the thermometer. Wichita (Wichita Eagle) reported 42 degrees below zero. The Hopkinsville Gazette (Kentucky) reported 40 degrees below. Washington DC reported 40 degrees below and the Portsmouth (New Hampshire) harbor froze over for the only time in its history. In Wyoming, a stage-coach mad... [More]

I think that was a meteorite that crashed into the Yucatan Peninsula.
