Enduring the worst winter in the world

Enduring the worst winter in the world

Nine months in Antarctica braving minus 80 C temperatures is one thing. It's the three months of darkness that really do you in
Dr. Alexander Kumar was sent to Antarctica to study the long-term effects of isolation as part of a European Space Agency team. He describes it as “the worst winter in the world."

There’s more to surviving winter at the South Pole than keeping warm and avoiding frostbite. It’s the psychological effects the extreme isolation and months of darkness have on the mind that pose the real challenge.

Just ask Dr. Alexander Kumar.

He recently wrapped up a year at Concordia science station in Antarctica, where he conducted research for the European Space Agency’s (ESA's) Human Spaceflight program.

The 29-year-old doctor has come out of the experience with his humor intact, but he now sports a shock of white hair in his dark fringe and has lost a lot of weight.

He does, however, have all his fingers and toes intact despite living through temperatures that fell to minus 80 C. 

Surviving the world's worst winter

“A lonely mind in Antarctica will sour and go off,” says Kumar, who spent much of his free time at Concordia taking photographs. Dr. Kumar was initially invited to join the Concordia team solely as a researcher for the ESA. Two weeks before they were due to set off, the Italian crew doctor pulled out. 

Aqualified doctor and anesthetist, Kumar took a five-day crash course in dentistry and agreed to step in.  

The team took a boat across the Southern Ocean, facing waves the size of houses and steering between icebergs until they reached Dumont d’Urville. From there it was a five-hour flight on a Twin Otter to Concordia station. 

As he watched the plane take off from the station he knew there was no way out for nine months. Whatever happened, they would have to wait until November before another plane could get through. Responsible for the health of the team, he was the only British member of the European crew of 13.

“Twelve men and one woman, not a winning formula,” he quips.

Antarctica is the coldest, most isolated place on the planet, with what Kumar calls “the worst winter in the world."

First there’s the extreme cold -- the minus 80.4 C low Kumar experienced is only nine degrees off the coldest temperature ever recorded on Earth (minus 89 C at the Soviet Vostok Station in Antarctica in 1983). If you add in the windchill factor, temperatures can fall as low as minus 100 C. 

To gauge just how cold this is, consider that if you breathe heavily and continuously -- say if you were running -- at minus 25 C or below your lungs will dry out, freeze and hemorrhage. On the plus side, Dr. Kumar could make iced coffee in less than three minutes by leaving his steaming coffee mug on the window ledge. 

Then consider the lack of oxygen. With 30 percent less than normal, breathing is difficult and it can take weeks to acclimatize.

Next comes the darkness. For three months the frozen South doesn’t see the sun at all.

“The isolation is very real,” says Kumar. “There is nothing around you for a thousand kilometers in most directions.” 

Perpetual jetlag, strange dreams and monsters of the mind

The Concordia station is 3,200 meters above sea level and temperatures drop to minus 80 C. No supplies can be delivered during the Antarctic winter and nobody can leave the base, no matter what emergency.The nearest neighbors were the astronauts in the Space Station far above, who they talked to occasionally. After one such chat ESA astronaut André Kuipers blogged about the Concordia crew: “They probably have a tougher time than we do up here. It is extremely cold at minus 80 C and when it is summer in The Netherlands they live in permanent darkness. The crew cannot leave, as the fuel in their vehicles is frozen and aircraft cannot reach them.” 

One of the most immediate effects of these extreme conditions is the effect on sleep.

“The Antarctic winter is like living in jetlag all the way through," says Kumar.

"When you wake up you don’t feel very revived. The sleep cycles are affected by altitude and daylight cycle. It's like having your circadian rhythm dangled, you feel like you are dangling precariously on a little thread that can be snapped by even someone making noise on the station at night.”

And the disturbed sleep makes for strange and vivid dreams. They were so intense that he can still recall some of them in detail.

“You wake up tired, thinking you’ve just lived for a day -- that’s how weird the dreams are,” he says.

Before he set off to the South Pole a colleague had warned, "You will have to face monsters, but the monsters will be your own."

It wasn’t until he was there, months into the mission and deep in the Antarctic winter, that he fully understood what that meant.

“You sit in that room at 4 a.m., staring back at the mirror at your own soul and your mind is stretched like Plasticine," says Kumar.

"Ultimate tensile strength is the utmost breaking point of a substance when it is stretched, taut. I think neurons probably have the same thing in the Antarctic winter.”

'It can be very dangerous to lose yourself'

“I went in with this romantic idea about polar exploration, but there is nothing romantic about living in three months of darkness and isolation,” says Kumar.No surprise then that it’s difficult, if not impossible, to function at peak performance -- even the concentration needed to read a book is tiring.

The crew had access to the Internet, but that could be a double-edged sword as news they were helpless to do anything about was “air-dropped” into the station. As the winter pressed on, many of the crew withdrew into their cabins and into themselves. Senses became blunted.

“A lonely mind in Antarctica will sour and go off. Those who were less busy really struggled,” says Kumar, who spent much of his free time taking photographs.

As the crew doctor, most of the problems he dealt with were psychological and a good deal of time was spent on counseling.

“People go stir crazy, they have to deal with the monsters of the mind. It can be very dangerous to lose yourself,” he says.

The toughest part of the winter is the last quarter, when all the fresh food has gone. He and the only Russian crew member, Igor, were the only two who watched the sun rise after the months of darkness.

“I went in with this romantic idea about polar exploration, but there is nothing romantic about living in three months of darkness and isolation,” he says.

Romantic notions aside, he is fast becoming the go-to doctor for extreme adventures. He has been advising Sir Ranulph Fiennes ahead of the veteran explorer’s upcoming winter crossing of Antarctica -- Fiennes and his team set off from London on December 6.

And Kumar will be the expedition doctor for the Imperial Trans-Antarctic Centenary Expedition 2014 that will attempt to cross the Antarctic from the Weddell Sea to the Ross Sea via the South Pole, finishing off what polar explorer Sir Ernest Shackleton set out to do in 1914.

Getting there 

Interested in checking out Antarctica yourself? A number of tour operators run regular excursions during the warmer months of the year. 

The International Association of Antarctic Tour Operators (IAATO) is an umbrella group representing 95 percent of the tour companies operating in Antarctica. Their website has a full list of member tour operators.

The companies on this list take precautions and protocols that meet or exceed those laid out by the Antarctica Treaty System for visiting vessels -- everything from waste disposal to the distance you should keep from wildlife to contingency plans in case things go wrong.
