And course this is hypothetical, but let’s say in a few years due to global warming that Antarctica becomes a temperate zone do you think it would be “good” place to live? Given the whole dark for months and then light for months thing, poor soil ECT.. And I guess it comes down to who owns it. Could I just move there and set up shop?

I would say no, because all humans occuping the "weather stations" out there are 100% dependent on the outside for supplies.

Again this is just hypothetical day dreaming, lets say with a warm climate kind of like what Eric the red found on the shores of Greenland. I think the South Pole has some areas like Iceland with geothermal fields why not set up an outpost there.

Probably not a nice place to live, but a little more "drillable".

Not that they'd ever do such a thing.....

What's wrong with it the way it is? I've seen the Thing (John Carpenter film), looks positively cushy. Ever read about those people who lived in Tierra Del Fuego - and ran around in the buff? Magellan or someone reported it.

Do people really believe Antarctica will become warm enough to be habitable in our lifetime (or even our children's)? I don't.

Ever heard of Lake Vostok?
It could be a bomb!
Yes a bomb ... down below ... Antarctica ...
8O

In clathrate structures, gases are enclosed in an icy cage and look like packed snow. These structures form at the high-pressure depths of Lake Vostok and would become unstable if brought to the surface.

Due to this high-pressure extreme environment, if water were to be released from Lake Vostok (from drilling, for example), it could gush like a popped carbonated drink can and, if not contained, open the lake to possible contamination and pose a potential hazard to scientists.

We are soooo smart....
Well we were .... 8000+ years ago ...

I am very curious as to what else is below all that ice.
Only a fool would deny the possibility of EASILY finding PROOF of former civilizations in a continent larger than the USA and in GREENLAND too...both.

When that ice melts .... 8O
All will be revealed.

Yeah man I watched the nature channel or someshit show about lake vostok and thats some scary naturally occurring poopee cockah right there 8)

Oh wait I see what you are saying.
In that case I hope the idiots flock to the place and find 100 billion barrels and then kaboom! :)
Yes muhahahah yes!
No wait! there could be some mega (size of people from texas who originally came from CT egos) deposits, smaller deposits could go and it could trigger a massive explosion causing an earth axis and of course magnetic shift along with crustal displacement which would bring about a new world void of Elitist order for a very long time hmmmm 8)

You there! boy with your "other" handle, your normal looking but still squishy inside head and your pseudo intellectually blinded faith in the current paradigm and what the teachers tit allows you to believe...What is your purpose here but to recite things we are already blungeoned with in k-12?
Lemme guess - yer religiously scientific?
Sorry that happened to ya but I am sure if you keep looking you will find the cure.

Notorious Ocean Current Is Far Stronger Than Previously Thought

The Antarctic Circumpolar Current is the only ocean current to circle the planet and the largest wind-driven current on Earth. It's also 30% more powerful than scientists realized.


173 Sverdrups!! Holy cow!

"[One sverdrup is equivalent to 1 million cubic metres per second (264,000,000 USgal/s).

The entire global input of fresh water from rivers to the ocean is equal to about 1.2 sverdrup " !!

Huge Antarctic iceberg poised to break away

Image

An iceberg expected to be one of the 10 largest ever recorded is ready to break away from Antarctica, scientists say.

A long-running rift in the Larson C ice shelf grew suddenly in December and now just 20km of ice is keeping the 5,000 sq km piece from floating away.

Larsen C is the most northern major ice shelf in Antarctica. Larsen C is about 350m thick and floats on the seas at the edge of West Antarctica, holding back the flow of glaciers that feed into it.

Researchers based in Swansea say the loss of a piece a quarter of the size of Wales will leave the whole shelf vulnerable to future break-up.

Last year, researchers from the UK's Project Midas reported that the Larsen C rift was growing fast.

But in December the speed of the rift went into overdrive, growing by a further 18km in just a couple of weeks. What will become a massive iceberg now hangs on to the shelf by a thread just 20km long.

However, they are concerned about how any break-off will impact the rest of the ice shelf, given that its neighbour, Larsen B, disintegrated spectacularly in 2002 following a similar large calving event.

Larsen ice crack continues to open up

Image

A chunk of ice half the size of Jamaica which is breaking away from West Antarctica is now attached to its parent ice shelf just by a thread, scientists reported Friday.

The rift in the Larsen C Ice Shelf has grown a further 10km since 1 January.

If the fissure propagates just 20km (12 miles) more, it will free a tabular berg one-quarter the size of Wales.

That would make it one of the biggest icebergs ever recorded, according to researchers at Swansea and Aberystwyth universities, and the British Antarctic Survey.

News of the lengthening crack in the 350m (1600 ft)-thick floating ice shelf on the eastern side of the Antarctic Peninsula comes from the EU’s Sentinel-1 satellite system.

When the berg splits away, interest will centre on how the breakage will affect the remaining shelf structure.

The Larsen B Ice Shelf further to the north famously shattered following a similar large calving event in 2002.

The issue is important because floating ice shelves ordinarily act as a buttress to the glaciers flowing off the land behind them.

In the case of Larsen B, those glaciers subsequently sped up in the absence of the shelf. And it is the land ice - not the floating ice in a shelf - that adds to sea level rise.

If Larsen C were to go the same way it would continue a trend across the Antarctic Peninsula.

In recent decades, a dozen major ice shelves have disintegrated, significantly retreated or lost substantial volume - including Prince Gustav Channel, Larsen Inlet, Larsen A, Larsen B, Wordie, Muller, Jones Channel, and Wilkins.

Ice all around the continent seems to be breaking up or melting in the case of sea ice:

http://www.bbc.com/news/science-environment-38643420

The British Antarctic Survey is to pull all staff out of its space-age Halley base in March for safety reasons.

The highly unusual move is necessary because the Brunt Ice Shelf on which the research station sits has developed a big new crack.
BAS officials say neither staff nor the base are in any immediate danger but believe it would be prudent to withdraw while the situation is assessed.
The plan would be to go back once the Antarctic winter is over, in November.
Halley station comprises a series of hi-tech pods that are mounted on hydraulic legs and skis so that they can be moved periodically further inland, to get away from the shelf edge where icebergs are calved into the ocean.

Unpredictable situation

BAS is in the process of conducting such a move right now. The relocation is all but complete, with the last pod currently in the final stage of being shifted 23km to the new site.
The move was necessitated by a chasm that had opened up in the shelf and which threatened to cut off Halley. But this huge fissure to the west of the station is not the cause of the temporary closure.
Rather, it is another break in the ice some 17km to the north and east of the new base position. It has been dubbed the "Halloween Crack" because it was discovered on 31 October.

Iceberg Size of Delaware Poised to Break Off From Antarctica

An iceberg the size of Delaware is poised to break away from Antarctica, an event which may lead to the collapse of a massive ice shelf on the continent, according to researchers.
Scientists say that a 1,900 square-mile section of the "Larsen C" ice shelf is now only connected to the main body by a 12-mile section of ice. Researchers monitoring a huge crack in the ice discovered that it had grown rapidly during the second half of 2016 — increasing in size by 11 miles in December alone.


Scientists have been monitoring the rift on the ice shelf for decades. Researchers told NBC News that the calving event was "part of the natural evolution of the ice shelf," but added there could be a link to changing climate, though they had no direct evidence of it.


In response to expressions of concern on social media, MIDAS scientists responded that there was no need for alarm. "This is a fairly normal event, although it is spectacular and quite rare


and perhaps one of the natural mechanisms at work here is described by this article (albeit not a journal published one)

Antarctica’s Larsen Ice Shelf Break-Up driven by Geological Heat Flow Not Climate Change

http://climatechangedispatch.com/antarc ... te-change/

The Larsen Ice Shelf lies in and among: twenty-six semi-active (non-erupting but heat-flowing) land volcanoes, four actively erupting land volcanoes, two proven semi-active seafloor volcano (seamounts), and a proven actively heat flowing major fault system named the West Antarctic Rift.
Not shown on this map are known seafloor hydro-thermal vents (hot seafloor geysers), likely heat emitting fractures, and prominent cone-shaped seafloor mountains that are most likely seamounts (ocean volcanoes).


This geological information paints a very clear and compelling picture that the Larsen Ice Shelf is positioned in an extremely active geological setting. In fact a strong case can be made that the Larsen Ice Shelf owes its very existence to a down-faulted low valley that has acted as a glacial ice container

If I understand the reporting methods used as long as the ice is stuck in place it doesn't get counted as floating sea ice, but as soon as it breaks free it becomes Antarctic Sea Ice. Because of the way the currents flow some of these huge icebergs bump a beach and get stuck where they slowly melt in place but others get carried north in just ba few months and melt in less than a year. I hope they track this one online so I can watch what happens.

The Larsen C rift was first noticed by MIDAS researchers in 2014, and has been monitored by satellites and other instruments ever since. In November 2016, NASA's IceBridge mission observed the immense crack, which then measured 70 miles (112 km) long, 300 feet (91 meters) wide and about one-third of a mile (0.5 km) deep.

Given the rate at which the rift is growing, the iceberg could break away early this year, MIDAS researcher Adrian Luckman, a professor of glaciology at Swansea University in the United Kingdom, told BBC News.

"Although you might expect any extension to hasten the point of calving, it actually remains impossible to predict when it will break because the fracture process is so complex," Luckman told BBC News. "My feeling is that this new development suggests something will happen within weeks to months, but there is an outside chance that further growth will be slow for longer than that."
