Antarctic ice sheet "past the point on no return"

What articles mention UNDERWATER VOLCANOES in conjunction with Antarctic ice? Links please.

Geothermal heat doesn't require volcanoes.

 

I can surmise that from observing the situation.Because I think outside the box.
I link only to myself.
Obviously you have never had an original thought.
But thats been apparent for quite a while.

 

I love you too.

 

Active Volcano Found Under Antarctic Ice: Eruption Could Raise Sea Levels

Subglacial volcanoes melting West Antarctic Ice sheet, say scientists - CSMonitor.com

 

Weak (magnitude 0.8-2.1) Deep Long Period earthquakes recorded under a (buried under a glacier) mound of earth that suggests previous volcanic activity. Not currently erupting. That is not what most of us think of when someone says 'active volcano'.

When it erupts, "global sea levels could rise by a small amount."

"This volcanic complex has been operating for millions of years ... There have been past eruptions of this system and the ice has survived for millions of years, [so] future eruptions alone will not cause the ice sheet to fail."

Mostly a repeat of the previous geothermal heat report, where some underground heat is adding the to the "hemorrhaging ice due to climate change," but some nice additional detail too.

And it points to good links too, such as another story about the DLP quakes mentioned in the first linked story above:

"It would take a super-eruption in the style of Yellowstone's ancient blowouts to completely melt the ice above the active volcano, Lough and her co-authors calculated. And if the volcano under the ice is similar to ones close by, such as Mount Sidley, there's no risk of a super-eruption."

""People hear the word 'volcano' and get caught up in the idea that it will change the way the ice sheet works, but this stuff has been going on underneath the ice [for millions of years], and the ice sheet is in balance with it," Lough said. "Everyday magmatism isn't enough to cause major problems.""

Following another link from this story, see in particular Myth #2 here:
5 Myths About Antarctic Melt
Here, Live Science explains the reality behind some common misconceptions about big changes in Antarctica.
1. Antarctic ice is getting bigger, not shrinking!
2. It must be all those volcanoes.
3. It's all a global warming conspiracy
4. The Earth will cycle itself into another ice age anyway
...

Thanks for the story links. They were far more useful and informative that the musing of mojo.

 

There is a strong drink called Apple Jack that starts with fermented apple juice. It is then partially frozen and the ice slush removed. The remaining liquid has a higher alcohol concentration than the original hard cider.

So I'm wondering if freezing sea water leads to a separation of floating, frozen, less salty water from a more concentrated brime? In effect, sea water purification by freezing that separates frozen water ice with less salt from the remaining, denser brime that sinks. I'm seeing references in Wiki to "brime rejection" "halocline" and "halothermal circulation."

Separating snow fall from the seawater formed ice would be a challenge. However, if lower ocean brine flows changed as a function of seawater freezing, we would have a metric, a measure of ice formation that should be seasonal.

Not just outside the box, but off the deep end too.

At least Spidey linked a useful article that does point to another interesting article, "Giant Undersea Volcanoes Found Off Antarctica". But that cluster is quite a ways off Antarctica, much closer to the South Sandwich Islands, at latitude S 56.09 degrees.

I'm finding the coordinates as being very roughly 100 miles SE of the South Georgia, more than 900 miles northeast of the tip of the Antarctic Peninsula, and more than 1200 miles off of the main body of Antarctica.

Not much warm water from that reaching the ice, nothing like Fire & Ice in Iceland.
