Antarctic tourism numbers are modest, but some nations seem to be eyeing up the continent’s industrial potential. Antarctic tourism numbers are modest, but some nations seem to be eyeing up the continent’s industrial potential. Supplied

Is there about to be a dash for Antarctica’s resources?

Few places have captured the human imagination like Antarctica. It is colder than anywhere on Earth, bounded by rough seas, buffeted by intense winds, home to fauna that are found nowhere else and, as…

Antarctic volcanoes help preserve life in the freezer

Antarctica was once covered in lush, subtropical forests, inhabited by diverse plants and animals including large dinosaurs. That’s going back many millions of years. These days, Antarctica is 99.7% covered…

Scientists at work: stuck in the Antarctic ice we set out to study

Antarctica is a desolate place. That much we know, but nothing prepares you for it until you actually get there. It’s cold, windy and lonely. Everything about it is the exact opposite of my normal summer…

We can all learn from Antarctica (when not stuck in the ice)

The drama and somewhat unintentional humour of first one and eventually three ships getting caught in heavy sea ice in the Southern Ocean has been closely followed since before Christmas. The images of…

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…

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?

Melting ice leaves polar ecosystems out in the sun

It is no secret that climate change is transforming the polar regions. Retreating glaciers, melting ice-caps and changing sea ice patterns are frequently reported in both the Arctic and Antarctic, and…

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…
