An international team has melted a hole through Antarctica's largest ice shelf to explore the hidden ocean below, and the shelf's vulnerability to climate change.
Australia must keep up its scientific presence in Antarctica and work with others if it's to maintain its territorial claim on the frozen continent.
Few fish can survive in these freezing waters, so invertebrates are the dominant predators.
Australia is among nations calling for a 1 million square km marine park off East Antarctica. But Russia and China remain opposed, and a recent summit yet again failed to seal the deal.

Notes unearthed from the British Library suggest that Captain Scott's Antarctic expedition may have been fatally undermined by Lieutenant Teddy Evans, furious after being sent back to base.
The treaty to limit the destruction of the ozone layer is hailed as the most successful environmental agreement of all time. Three decades on, the ozone layer is slowly but surely returning to health.
The climate secrets contained in an ancient tree that lived through abrupt global change reveal how Antarctica can trigger rapid warming in the north by dumping cold water into the Southern Ocean.
Mosses are sensitive to even minor changes in their living conditions, and scientists traditionally tramped through difficult terrain to collect data on them.
18,000 years ago a volcano in Antartica began erupting – and didn't stop for 192 years.
More than 100 volcanoes lie beneath the continent's ice sheet.
Analysis of 12,000-year-old Antarctic ice reveals that methane leaks from fossil fuel extraction play a larger role than previously thought.
Fruit cake may last a century, but it's got nothing on honey.

What would possess an Antarctic expedition to take dairy cows to the icy continent? Back in 1933, Admiral Byrd did so for reasons of image-making, publicity and territorial ambition.
Enormous Antarctic icebergs are a rare but natural occurrence.
A huge iceberg is set to break free from Antarctica. While the iceberg isn't hugely concerning, it could herald the breakup of the entire Larsen C ice shelf, which could trigger more sea-level rise.
Set aside the politics. If by some miracle we turned off carbon emissions immediately, how would the climate respond?
Climate change is set to expand Antarctica's ice-free area, potentially helping native species to flourish but also paving the way for invasive species to gain a foothold.
