Building a telescope in the coldest place on Earth

Russia’s Vostok station in Antarctica must be one of the scariest places on Earth. Temperatures regularly drop below -80C, and there is no way in or out for nine months of the year. The inhabitants become…
Tractors and quad bikes – seen here at Australia’s Mawson Station – are only two of many forms of transport used in Antarctica. Chris Wilson/Australian Antarctic Division

Why the ‘infrastructure PM’ can’t give Antarctica the cold shoulder

Prime Minister Tony Abbott recently declared that he wanted to be known as the “infrastructure prime minister”. But what of Australia’s iciest infrastructure – that located in Antarctica? A 20-year strategic…

Was penguin evolution driven by a cooling Antarctic?

Penguins are a remarkable group of flightless birds. We tend to think of them as Antarctic birds, but they actually inhabit an extremely diverse range of habitats from subzero Antarctic coastline to the…

Why is Antarctic sea ice growing?

Recently NASA reported that this year’s maximum wintertime extent of Antarctic sea ice was the largest on record, even greater than the previous year’s record. This is understandably at odds with the public’s…
Even with water temperatures down to -20°C, Deep Lake is home to a surprising amount of life (and not just our research camp). Rick Cavicchioli

Sub-zero heroes: extremophiles call salty Antarctic lakes home

Imagine a lake so salty its water exists in a liquid state at -20 °C – then picture something thriving in that seemingly lethal environment. Such an organism exists; several of them, in fact. In a paper…

IPCC: where to for Antarctica and the Southern Ocean?

The general thrust of the IPCC’s Fifth Assessment Report - released on Friday – can be summarised as: “there is now more evidence that climate change is occurring”. Antarctica and the Southern Ocean are…
Lack of funding is just the tip of the iceberg for Australian Antarctic research. AAP/Australian Antarctic Division

Australian Antarctic science is being frozen out by budget cuts

A hundred years after Australian explorer and geologist Douglas Mawson returned from his epic scientific adventures in Antarctica, Australia’s scientific exploration of the icy southern continent has all…
Antarctic warming began at least two, and perhaps four, millennia earlier than previously thought, the study found. NASA Goddard Space Flight Center

Last Antarctic ice age melt began earlier than first thought

The Antarctic warming that signalled the beginning of the last ice age melt may have actually started between between two…
Russia has turned its back on marine protected areas in Antarctica. Where to now? Flickr/US Embassy New Zealand

Antarctic marine reserves: how many ways can you say “Nyet”?

Russia blocked the approval of new marine protected areas in the Antarctic this week, demanding more scientific information and a definition of marine protected areas. The surprise move postpones a joint…
Antarctica’s ice is melting in different ways in different places: what’s the connection? AAP Image/British Antarctic Survey

Explainer: what is happening to Antarctica’s ice?

Two papers released last week in the journal Nature Geoscience provide evidence that warming and melt in West Antarctica are occurring at levels that are highly unusual compared to natural variability…
