Just to clarify, this isn’t Orin’s first season – He worked with me (and played in a band with me) at Pole two years ago.
I did my best to go back far enough to figure out if they were repeaters, but I’m not surprised that I missed a few things. Thanks for the catch! 🙂November 14, 2011 at 3:31 pm #6570
Since it’s summer at Pole, I’ve added some new blogs (and cleaned out most of the old dead links 🙁 )November 17, 2011 at 1:44 pm #6571
Not really a blog but saw this story on MSNBC this morning….

This graphic provides a three-dimensional perspective of the Gamburtsev Subglacial Mountains, including a view of the deep root imaged beneath the range and of the thinner crust of the East Antarctic Rift System that surrounds the mountains.
LONDON — The mystery of how a subglacial mountain range the size of the Alps formed up to 250 million years ago has finally been solved, and that could help scientists map the effects of climate change.
The Gamburtsev subglacial mountains are buried 2 miles (3 kilometers) below the East Antarctic Ice Sheet, the largest remaining body of ice on the planet.
Experts are trying to learn more about the frozen continent, as even a small thaw could swamp low-lying coastal areas and cities. Antarctica contains enough ice to raise world sea levels by about 187 feet (57 meters) if all of it ever melted.
Discovered in 1958, the mountains’ origin has largely been an enigma until now.
Around 34 million years ago, there was an abrupt decline in levels of carbon dioxide in the atmosphere, which prompted the glaciation of Antarctica. The process began over the Gamburtsev Mountains, said Fausto Ferraccioli, lead author of the report and geophysicist at the British Antarctic Survey.

On top of the mountain range, there is a strong possibility of finding the oldest ice on the planet, which could be 1.2 million years old or more, he said. Until now, scientists have been able to study ice going back only 800,000 years.
Based on radar, gravity and magnetic data, scientists from seven countries found a tectonic process called rifting was the trigger that lifted up the Gamburtsev mountains.
The findings, published in the journal Nature, showed that several continents collided around 1 billion years ago, crushing the mountain’s rocks together. This formed a huge root which extended deep beneath the mountain range. Although the mountains eroded over time, the root was left behind.
When rifting occurred up to 250 million years ago, the root warmed up, which forced land upwards to re-form the mountains.
The East Antarctic Ice Sheet, which covers 10 million square kilometers, protected the mountains from erosion.

“In particular, the fluvial and glacial valleys were responsible for uplifting the peaks and making the mountains look like the Alps. Their present-day aspect is strongly influenced by climate and ice sheet evolution,” said Ferraccioli. “Understanding long-term ice sheet evolution is critical in order to develop more realistic models of variations of the ice sheet to climate change.”
The mountains could also contribute to the long-term stability of the ice sheet.
“The ice sheet and climate models would suggest you can still maintain an ice sheet in the interior of East Antartica over the mountains even if the temperature rise were 10 degrees (Celsius) above the present day — perhaps even as much as 15 degrees,” Ferraccioli said.

Great News, I have a phone interview coming up with Gana A’Yoo. Ms. Massey contacted me to inform me that someone will e-mail with the details. She mentioned that it might be a while as I applied earlier then most folks do but that that’s good. Now they need to catch up. I applied for five positions, both at McMurdo and the Pole and they have only considered me for one so far. A couple of positions are not available as folks are returning. But, I’ll take what I can get. I’ve done my interview homework and feel somewhat prepared but if those of you who have gone through this process (phone interview) have any advice I would sure appreciate it. What else can I do to be at the top of my game.

Hi all. Due to head out to Halley in December with the Britisg Antarctic Survey.
been lurking and reading for while before getting the job (in the hope of getting any info for my interview-and it worked!).
I’d like to post up a link to my blog- it’s slow going at the moment, crevasses and auroras to come I hope. the blog is written to be read by kids and is fairly simply written- though I may wax a bit more lyrical when I’m out there!
