Color photographs of Ernest Shackleton's 1914 Antarctic expedition by Frank Hurley.
Early in 1915, their ship 'Endurance' became inexorably trapped in the Antarctic ice. Hurley managed to salvage the photographic plates by diving into mushy ice-water inside the sinking ship in October 1915.
There are two ATM machines in Antarctica. They are located at McMurdo Station and operated by Wells Fargo. Here's an interview with a Wells Fargo VP about the unique challenges of operating those machines.
You know, the other thing too that you may find interesting -- I don't know how much you know about folks that need to go down to Antarctica -- it's a huge process to do it. So when we're preparing for the vendor visit, it's like a ten-month process. The reason being is, they obviously go in the off-season when it's obviously warmer because no planes fly onto the ice in their winter months. And so anybody that goes to Antarctica has to be cleared with a physical, a dental, and a psychological evaluation, because if for some reason the plane can't get out, you're trapped down there until the next season.
Maciej Ceglowski tells the story of how the cure for scurvy was discovered, lost, and finally redsicovered, but not before it disrupted Robert Falcon Scott's 1911 expedition to reach the South Pole.
This is a good example of how the very ubiquity of vitamin C made it hard to identify. Though scurvy was always associated with a lack of greens, fresh meat contains adequate amounts of vitamin C, with particularly high concentrations in the organ meats that explorers considered a delicacy. Eat a bear liver every few weeks and scurvy will be the least of your problems.
But unless you already understand and believe in the vitamin model of nutrition, the notion of a trace substance that exists both in fresh limes and bear kidneys, but is absent from a cask of lime juice because you happened to prepare it in a copper vessel, begins to sound pretty contrived.
Antarctic ice isn't melting as much as predicted because the overall global warming trend and the Antarctic hole in the ozone are at cross purposes with each other. Temporarily.
As the ozone hole heals in the coming decades, the winds will weaken, the continent will become much warmer in summer -- and melting will increase.
In 1961, surgeon Leonid Rogozov was the only physician stationed on an isolated 12-man Soviet base in Antarctica when he developed appendicitis. He had to remove his appendix himself.
"I didn't permit myself to think about anything other than the task at hand. It was necessary to steel myself, steel myself firmly and grit my teeth. In the event that I lost consciousness, I'd given Sasha Artemev a syringe and shown him how to give me an injection. I chose a position half sitting. I explained to Zinovy Teplinsky how to hold the mirror. My poor assistants! At the last minute I looked over at them: they stood there in their surgical whites, whiter than white themselves. I was scared too. But when I picked up the needle with the novocaine and gave myself the first injection, somehow I automatically switched into operating mode, and from that point on I didn't notice anything else.
Anticipating cries of "photos or it didn't happen", his assistants documented the scene: here's Rogozov operating on himself (and another).
Down 50 pounds, running on 15% lung capacity, and unable to remember coordinates properly, Todd Carmichael works his way toward the South Pole, still attempting to set a speed record.
"I just don't know what to do," Carmichael says to the camera. "No way of communicating with anyone. No way of making water." His voice rises with resentment. "I have no water! That's it. I have no water. If you don't have water, you don't have life."
The two comments following the story are also interesting. One is from a member of a Canadian team who broke the speed record a few days after Carmichael's attempt ended.
The abandoned supply shacks of Antarctic explorers Robert Falcon Scott and Ernest Shackleton are still intact and have been preserved by the cold.
While the preservation of food in the freezing temperatures and dry climate has been noted, bacterial decay still occurs. Besides, the World Monuments Watch describes it as one of the hundred most endangered sites in the world, and New Zealand's Antarctic Heritage Trust (AHT) has been working in the last years to preserve it from corrosion.
These structures and the supplies contained within are almost 100 years old.
Let's talk Antarctica blogs.
Antarctic Journal is one of the best; it's written by a grad student studying penguin ecology. Big Dead Place is also great (but not strictly a blog); check out the stories and interviews section. Also of note but of varying quality and timeliness are a blog by the British Antarctic Survey, John Bean's Antarctica blog, a U of Delaware blog, Antarctic Blog, and Antarctica Blog.
I'm still looking forward to the SOUTH expedition blog whenever that happens.
Update: One more: 75 Degrees South. Very nice photos, as in this post. (thx, pete)
Update: More Antarctica blogs and such: UAB in Antarctica, Blog Rogers (which includes info about the book, Antarctica: Life on the Ice), Nathan Duke, elisfanclub, Concordia Base, Base Dumont d'Urville, Mr Rose Géophy CZT45, and Andrill. (thx, everyone)
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."
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."
