The scale of the IceCube neutrino detector is amazing…a cubic kilometer telescope 1.5 miles deep into the ice caps of Antarctica. (via pruned, which has more thoughts on the architecture of particle physics)
Antarctic glaciers are losing ice, but not because of melting. “In Greenland we know there is melting associated with the ice loss, but in Antarctica we don’t really know why it’s happening.”
English, as She is Spoke at McMurdo and Pole, AKA slang from Antarctica. (via his purpleness)
Scientists have extracted ice cores from Antarctica that date back 650,000 years (the previous high was 400,000 years). The cores show that modern levels of carbon dioxide, methane, and nitrous oxide levels are the highest they have ever been.
Ben Saunders is a little bit crazy. He does stuff like ski solo from Russia to Canada via the North Pole just for the heck of it. When I was last in London, I called him up to make dinner plans and he apologized if he seemed a “little” tired because he’d been out for a “bit” of a run this morning. That short run turned out to be 20 miles. (At dinner that evening, Ben and his training partner, Tony, ate everything on the table short of the cutlery.)
Ben’s latest endeavor is his upcoming expedition across Antarctica to the South Pole, dubbed SOUTH:
Here’s the plan. The first return journey to the South Pole on foot and the longest unsupported polar journey in history. In October next year, Tony Haile and I will set out from Scott’s hut, on the shores of McMurdo Sound on a 1,800-mile, four-month round trip, from the coast of Antarctica to the South Pole and back. No dogs, no vehicles, no kites, no resupplies. We’re calling it SOUTH.
The great Norwegian explorer Roald Amundsen made the only return journey, using dogs, 93 years ago. His rival Captain Scott died on his return from the Pole just 11 miles from the relative safety of his largest depot. Since then every expedition has either been flown out from the Pole or used dogs, kites or vehicles. Many people have blamed Scott’s failure on his reliance on human power, and many experts still believe an entirely human-powered journey of this magnitude to be impossible. We think otherwise.
Expeditions of this sort are generally funded by large corporations who give money in exchange for advertising and sponsorship opportunities. On his last expedition to the North Pole, Ben blogged (and photoblogged) daily using a PDA & satellite phone and was cheered along by the thousands who read and commented on the journey. So for SOUTH, Ben and Tony are doing something a little different…they are seeking financial support from private individuals (and companies/groups/etc.). For a donation of $100, you can “own a mile” of the expedition, which means you get a listing on the site, a listing on the front page when your mile of the expedition is completed, your name enscribed on one of the expedition sleds, and your name on a flag planted at the South Pole. Ben and Tony are great guys and I would love to see them succeed, so give them a hand if you can.
Antarctic base will be built on skis. The movable station “will prevent the possibility of the base drifting out into the ocean on the back of an iceberg that has ‘calved’ off the shelf”.
How to turn a block of Antarctic ice into a giant neutrino detector. “To turn the ice into a telescope, all you have to do is drill an array of 80 holes half a meter across by 2.5km deep using a very powerfull jet of hot water. Then lower a string of 60 optical detectors into each hole before they refreeze, conect them up to some powerful computer analysers and you are good to go.”
