Nearly thereFeb 05 2014

Ben Saunders and Tarka L'Herpiniere are reaching the end of their 105-day, 1800-mile solo (nearly) unsupported journey to the South Pole and back again. Towing sledges across unchanging icy terrain for 100 days doesn't exactly make for compelling reading, but it's been a highlight of each morning during the past three months to read what the boys have been up to. I hope offering my congratulations on a job well done isn't premature.

The forests of AntarcticaJan 28 2014

There is fossil evidence that Antarctica may have been covered by forests.

The discovery has come in the form of fossilized impressions of wood and leaves in the region of Antarctica's Mount Achernar. Even the stumps of ancient tree trunks have been uncovered, believed to date back to prehistoric times.

It is commonly accepted that during the late Permian and early Triassic periods, as much as 250 million years ago, the whole world would have been far hotter than it is today.

Sarah Feakins, a biogeochemist from the University of Southern California, posits that the Antarctic coast was once lined with beeches and conifers; based on evidence taken from leaf waxes found in sediment cores extracted from the Ross Ice Shelf.

A period of warmer climate around 15 million years ago, known as the Miocene period, could have had areas of the Antarctic resembling the kind of forested tundra seen today in New Zealand or parts of Chile. Chemical study of the leaf wax samples indicates that during the summer months, the coast of Antarctica could have been as warm as 15°F.

Fear and loathing near the South PoleJan 02 2014

70 days ago, Ben Saunders and Tarka L'Herpiniere set out from the edge of Antarctica, bound south. Their goal was to ski, alone and unsupported, to the South Pole and back along the route Captain Robert Falcon Scott travelled in 1912. I've been following their blog every day since then, and they were making the whole thing -- skiing 19 miles/day in -30° white-outs hauling 300 lbs. and blogging about it the whole way -- seem easy somehow. They reached the Pole the day after Christmas were hauling ass (and sled) back toward the coast.

But their seemingly steady progress hid a potentially life-threatening truth: they needed to be skiing more miles a day in order to travel quickly enough to not exhaust their food supply. They'd been missing their mileage goals and in an attempt to catch up, weren't sleeping and eating as much as they should have been. Things could have gone very wrong at this point, but luckily Ben and Tarka came out ok.

Our depot was still 74km away and we had barely more than half a day's food to reach it; eight energy bars each, half a breakfast and half an evening meal. 16km into the following day Tarka started to slow again as he led, before stopping entirely and waving me forward to talk. "I feel really weak in the legs again", he said. "OK. What do you want to do?" I answered snappily, before realising this was on me. I came here to be challenged and tested, to give my all to the hardest task I have ever set myself and to the biggest dream I have ever had. And here was the crux. This was the moment that mattered, not standing by the Pole having my photograph taken, but standing next to my friend, in a howling gale, miles away from anyone or anything. "Let's put the tent up", I said, "I've got an idea".

Adventure is never about battling the environment or elements or whatever. It's always a struggle with the self. And as this battle reached a fevered pitch, Ben and Tarka were not found wanting. Calling for resupply, and thereby giving up on one of the major goals of this expedition 10 years in the making, was probably the hardest thing Ben has ever had to do in his entire life. But he did it, for his family, his loved ones, and his teammate. Ben, Tarka, I'm proud of you. Thank you for letting us follow along on your journey, for showing us what is humanly possible, and for the reminder that pushing the boundaries is never about how far you can tow a sled but about what you do when confronted with the no-win scenario: beating yourself.

There and back again, South Pole editionOct 28 2013

Scott Expedition

Right now, two men on skis pulling 440 lb sleds are inching their way across the Antartic continent, bound for the South Pole and then back again. Ben Saunders and Tarka L'Herpiniere are attempting to complete, solo and unsupported, the same journey that claimed the lives of Robert Falcon Scott and his party in 1912. They're calling it The Scott Expedition.

Saunders has been working towards this goal for more than 10 years with many false starts. His former partner in exploration, Tony Haile, explains the journey before the journey:

In short, a South Pole expedition is pretty much the worst way to spend four months you could possibly imagine, but if you were to ask Ben I don't think he would say that's the tough part. The tough part is getting to the start line in the first place. Antarctica is far away from everywhere and doing anything in Antarctica is ridiculously expensive. Imagine if you kept a car in New York but the only way to fuel that car was to charter a private jet and fly fuel in from England. That's the logistics of an Antarctic expedition and between us we had no cash and no clue how to get any.

We didn't go to the South Pole in 2003. Or 2004. Or 2005. Living month to month on whatever I could scrounge together, putting together small expeditions or managing other people's just so I wouldn't lose my connection to the cold places, I grew to fear and then hate my parent's yearly Christmas letter to their friends which would explain 'Anthony has decided to postpone his South Pole expedition for another year to raise more funds'. For Ben and I, we had proclaimed a grand goal. We had told people year after year this was the year we were finally going to go south. And every year we had to look at the nervous smiles as we publicly failed. Again and again.

The journey is just underway...the plan is to travel 1800 miles to and from the South Pole and you can track their progress online and read tweets and blog posts from Ben and Tarka along the way. Back in 2005, when Ben and Tony were planning this trip the first time around, they sold miles of the expedition for donations of $100 apiece. They didn't make it that year obviously and in the days before Kickstarter, crowdsourcing $180,000 was a bit more difficult than it is now. But I bought a mile back then (I actually got mile #900, the point at which they'll reach the pole) and I am beyond excited that they've set off and can't wait to see how the trip progresses. Good luck, Ben and Tarka!

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.

ATMs in AntarcticaJul 21 2010

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.

Rediscovering the cure for scurvyMar 09 2010

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.

Why Antarctica isn't melting muchJan 20 2010

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.

Auto-appendectomy in the AntarcticJan 20 2010

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).

To the South Pole on footMay 05 2009

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 explorersApr 17 2008

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.Jan 21 2008

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)

Antarctic glaciers are losing ice, but notMar 17 2007

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 AntarcticaNov 30 2005

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.

Heading to the South Pole and back...on skisJul 21 2005

I'm supporting SOUTHBen 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 skisJul 19 2005

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 AntarcticMay 17 2005

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."
