19. Though at the time this was the most winters anyone had spent there, that particular record has now been exceeded. At the time of writing, Robert Schwarz has spent seven winters there, and Steffen Richter shares the current record of eight winters with a man named Johan Booth. However, Jake's record still stands for the most consecutive winters. For the latest on this and other South Pole wintering statistics, see

1. EPICA was funded to the tune of more than €7 million by the European Commission, Belgium, Denmark, France, Germany, Italy, the Netherlands, Norway, Sweden, Switzerland and the United Kingdom. The project involved a second core at Dronning Maud Land near the coast, which was drilled after the one at Dome C was finished. See the European Science Foundation EPICA website at
http://www.esf.org/index.php?id=855

3. The lowest reliably measured temperature on Earth, -89.2°C, was recorded at Vostok on 21 July 1983.

4. One of the meteorologists, Guillaume Dargaud, recorded the experience in an excellent blog:
http://www.gdargaud.net/Antarctica/
WinterDC.html. In fact the record low was -78.6°C. The rest of Guillaume's site is full of fascinating information about Concordia and Dumont d'Urville, as well as Antarctica in general.

5. The same experiment was deployed at the South Pole in 2002 within earshot of the station. It ‘mysteriously' failed at the beginning of winter.

6. The answer turned out to be complex, but fascinating. See Gabrielle Walker, ‘Antarctic astronomy: Seeing in the dark',
Nature,
vol. 438, 24 November 2005, pp. 414–15.

7. Although Vostok was deeper than the EPICA core, the thicker ice there insulated the base more, making it harder for the slight heat radiating from the inside of the Earth to escape. Thus, the oldest layers have melted away and turned into a giant under-ice lake.

6. A Human Touch

3. I have made three return trips to the Peninsula by ship, once on the US National Science Foundation's
Nathaniel B. Palmer,
once on the
Akademik Sergey Vavilov
, a Russian research ship chartered for tourist trips by Peregrine Adventures, and once aboard the Royal Navy icebreaker HMS
Endurance
, which was supporting the scientific activities of the British Antarctic Survey. That makes six crossings in total. And every time, Drake Passage has been as flat as a mirror. It can't be a coincidence. I am clearly some kind of charm—lucky or unlucky depending on what you wish for. If you decide to make this trip and you're worried about seasickness I suggest you take me with you. But if you want the full experience—the romance of some heavy winds to write home about—make sure I'm not on board.

7. Sadly, the HMS
Endurance
is now out of commission. Owing to a problem with her valves she came close to sinking in the waters of South America in 2009; though she was returned to the UK, the repair bill would have been too great and she has now been scrapped, to be replaced with a Norwegian icebreaker.

8. The first report of this dinosaur was: E. Olivero, R. Scasso and C. Rinaldi, ‘Revision del Grupo Marambio en la Isla James Ross—Antartida',
Contribución del Instituto Antartico Argentino,
331, 1986, pp. 1–30; however, it took more than a decade to assemble all the available pieces, and the new species was not named until 2006, in Leonardo Salgado and Zulma Gasparini, ‘Reappraisal of an ankylosaurian dinosaur from the Upper Cretaceous of James Ross Island (Antarctica),
Geodiversitas,
vol. 28, 2006, p. 119.

11. The cooling happened in fits and starts, and ice ages were, of course, generally colder than intervening warm periods such as the one we have today. But the overall trajectory has been securely downwards. See, for example, Hodgson et al., ‘Antarctic climate and environment history in the pre-instrumental period', p. 123.

Scientists think the warming on the Peninsula comes from a combination of the rise in greenhouse gases (from our human burning of coal, oil, gas and trees) and a nasty side effect of the loss of the ozone layer (from our human creation and use of ozone-destroying chemicals).
