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…
Melting ice, growing ice, and shifting acidity: what the future holds for the great white south. AAP Image/Dean Lewins

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…
Antarctica’s delicate marine ecosystems are under threat from climate change and ocean acidification. wikimedia/Steve Clabuesch

Warning bells: what Antarctica can teach us about ocean acidification

When it comes to climate change, temperature is only part of the story. Climate gases released by human activity are dissolving into the oceans, and the increased levels of CO₂ are making the waters more…
Will the remote continent be spared the devastating impacts of human activity? Flickr/v1ctor.

Final frontiers: Antarctica

With the global population now well over seven billion there are few remaining parts of the world relatively untouched by human activity. We assess the current state and future prospects of five final…

Antarctic sea ice bucks trend

Sea ice is expanding in the seas around Antarctica. Unlike in the Arctic, where sea ice has suffered a drastic decline in…
We can learn a lot about the conditions life can endure by looking under the ice of Antarctica. Eugene Kaspersky

A life less ordinary: looking under the surface of Lake Vida

The search for life in extreme environments is an exploration not only of the robustness of earthly life, but also of our origins. And perhaps the biggest question here is whether the earth is a unique…
Failing to reach a decision on protecting Antarctic waters doesn’t mean the process is over. Dean Lewins/AAP

Don’t write off Antarctic marine protected areas

The annual meeting of the Commission for the Conservation of Antarctic Marine Living Resources (CCAMLR) wound up in Hobart on Thursday last week without declaring a system of marine protected areas (MPAs…
By studying ice cores, researchers can measure the methane emissions from thousands of years earlier. Arabani/Flickr

Humans did affect the atmosphere - even before industrialisation

The past is the key to the future. When snow falls on polar ice sheets, in Greenland and Antarctica for example, air is trapped between the snowflakes. Year after year, the snow compacts under its own…
Sea levels are rising globally at record-breaking rates and Antarctica is playing an increasing role. Matt King

Weigh-in reveals Antarctica’s losing 190 million tonnes a day

A small slice of Antarctica turns up along your coastline each year. We’re all glad it’s just a small slice, given Antarctica could deliver a total sea-level rise of 59 metres. That’s not going to happen…
