updating the story
It appears the attempt failed, at least for now. https://secure3.aad.gov.au/proms/public/schedules/display_sitrep.cfm?bvs_id=19314

Re:Read "Big Dead Place" before going
Well the Australian stations are run by the Aussie Federal Government directly - the jobs aren't outsourced to some third party. Check out their web site at http://www.aad.gov.au/ to find out what they get up to.

Re:What about the South Pole?
So, does the South pole shift as well?
Yes.
To where?
Antarctica isn't divided up into countries, so it's moving from Antarctica to Antarctica*. That's like saying it's gone from the middle of nowhere (with penguins) to also the middle of nowhere (with penguins): there's just no way of making that an attention grabbing story, despite the penguins.
*To be technical, magnetic South is near the edge of the sea ice rather than on the continent, which means it's moving from a really cold bit of ocean to another, slightly less cold bit of ocean. While that does entail more penguins, it's still not that interesting.

Re:Polar PhotographyThat's a fantastic picture, thanks. I'm fairly sure Antarctica is populated all year round. It is far easier to get to than the ISS, and I'm sure most scientists would feel a similar thrill staying at either one.
So I checked, and according to the Australian Antarctic Division:
No more than a few thousand in the height of summer, going down to hundreds over winter. The most populous antarctic centre is McMurdo Base on Ross Island, south of New Zealand, operated by the United States. Australia's four stations have winter-time populations totalling around 80 in winter, rising to perhaps 200 in summer. In addition, marine scientists spend a lot of time on research boats in the Southern Ocean during the summer months.So there you have it. Thanks again for the pic, and don't fret, APOD is never off-topic!

Re:The other side the matterI'm sorry if I overreacted; I'm from New Zealand and the ozone hole is a big deal around here. My memory from school is that because Antarctica (a big freakin' continent), rather than frozen ocean, is at the south pole the winds are stronger, or more stable or something. So although more CFCs were released in the northern hemisphere, most of the mixing between the upper and lower atmospheres happens in Antarctica. I can't find the right query to get google to tell me precisely, but this touches on it:
http://env.chass.utoronto.ca/env200y/know/ozone.ht mlIs it possible that other processes might start to consume ozone, an Arctic ozone hole for example? We don't know. Periodically, large depletions in ozone (more than 10-20%) have been reported from the high northern latitudes. While the processes that lead to this decrease are similar to those at the Antarctic, the pattern has not been similar. The Arctic polar vortex is weaker than the Antarctic one. Stratospheric temperatures at the Arctic are not as low as those at the Antarctic, hence PSC formation is reduced. However, global warming . may strengthen the Arctic polar vortex. We already know that stratospheric temperatures are falling, so it is possible that an Arctic ozone hole could develop in the future. It would likely be smaller and weaker than the Antarctic hole, but could have serious consequences for Canadians.
And to answer your second point:
http://www.aad.gov.au/default.asp?casid=11427Scientists investigating the 2006 ozone hole have used a range of instruments to measure ozone concentrations, including satellites, balloons, and ground-based spectrometers and gas samplers. Measurements showed that the area of the hole was greatest on 24 September, with an area of approximately 29 million square kilometres, more than twice the area of Antarctica.
For those who are interested, Wikipedia tells me that the area of the United States is a tad under 10 million square miles - so the Antarctic ozone hole is three times the size of the US. -
Geology professors in Antartica
My Geology professors had an interesting solution when they went to Antartica in the late 1970's and had to name all sorts of newly discovered features, some got named after themselves. If you don't believe me here it is.

Re:Already divied up?
The Antartic has beed divided up already and Australia has a majority stake in it, Australian Antartic Territory has its own stamps these days and is counted as part of Australia's territories along with places such as Papua New Guinne and Christmas Island (of goatse fame)
Australia came to own this stake in 1961 when a treaty was signed by us and 11 other countries and since then 45 more countries have signed the agreement.
More information here and a complete list of signitories here
A nifty map can be found in PDF form here
And an example of the stamps here
note New Zealands crappy share... suck on that kiwi's -

Did I say brrrrrrrrr?
Yes, it does get colder there.
-
Pictures? No worries, try...
...this. Currently pitch black, 9AM, -13degC and 90km/h winds. Brrrrrrrrr.
-
Dermal carcinomas? No worries, UWA is big on that
Seriously, is it such a big threat compared to frostbite, freezing to death if your car breaks down, roads covered in snow, slush, salt and sometimes ice, or driving on the French side of the road? (-:
Don't spend your life sunbaking, do eat fresh food and exercise a bit and your odds against skin cancer are good. In short, be sensible. It's nothing like the ad in the leaders before Terminator 2. (-:
Also, if you like cold, perhaps we could find you a job at Mawson Station? -
10 facts about GentooCan be found here. For example:
Gentoo penguins (Pygoscelis papua) breed on subantarctic islands and on the Antarctic Peninsula in small to large colonies. Larger populations of gentoo penguins are found at South Georgia, the Falkland Islands and the Iles Kerguelen.
Gentoo penguins are the least abundant of the penguins found on the subantarctic islands, with a total breeding population of approximately 314 000 pairs.
Unlike other penguin species, gentoo penguins may breed as early as two years of age.
The gentoo penguin is a medium sized penguin, standing 75-90cm tall and the females are smaller than the male birds.
Given that the penguin has a latin name, should the full name of this distro be:
Connochaetes taurinus/Pygoscelis papua Linus ? -
Gentoo Etymology (Why's it called that?)I think it is worth mentioning the etymology of the name "Gentoo" for this distro. I believe that back in the day, it used to be called "Enoch", but then they decided that they needed a new name... something based on penguins (of course!). Thus Gentoo was chosen, being (I think) a type of penguin known for being the best and fastest swimmer of all penguins.
So here's some obligatory Gentoo links for you zoologoy freaks:
Gentoo penguin : "The Gentoo penguin is a member of the genus Pygoscelis, which contains two other members, the Adelie and the Chinstrap. When inspecting the three, the Adelie looks more like the odd one in the group of three. Chinstraps and Gentoos share more morphological features, but the Gentoo is the most colorful of the three with its orangish beak and pinkish-orange feet. They can also be positively identified by an interorbit band of plumage that runs superiorly over the head."
Seriously though, Gentoo Linux sounds really cool. I'm a die-hard Debian guy (especially with Woody going stable in May)... but I plan on giving Gentoo a try this week. And I wish the best to the developers.Pete & Barbara's Page : "Males have their maximum weight of about 8 kg just before moulting and their minimum weight of about 5.5kg just before mating. For females the maximum weight is 7.5kg just before moulting but their weight drops to below 5 kg when guarding the chicks in the nest."
Gentoo Penguin: 10 Facts : "Adults can be found throughout the year on breeding islands indicating that they are relatively sedentary. They feed on Rock cod, amphipods and cephalopods (mainly squid). Females tend to eat more krill than the males, while the males tend to eat more fish than the females. It is thought that gentoo penguins are gregarious at sea."
