The Small Planes That Circumnavigated Antarctica’s Grounding Line

Two ski-equipped Twin Otter aircraft spent the 2024/25 austral summer attempting something rarely achieved in Antarctic science: circling an entire continent while collecting critical data from one of the most important, and least visible, boundaries on Earth.

Antarctic Tourism’s Ethical Tension Draws Fresh Scrutiny

A new academic study examining former Antarctic tour guides has reopened a long-running debate over the role of tourism in one of the planet’s most environmentally significant regions, prompting a detailed response from the International Association of Antarctica Tour Operators (IAATO).

How Horizon Scans Help Set Antarctica’s Research Agenda

Over the past decade, horizon scanning has become one of the most influential tools used by the Scientific Committee on Antarctic Research (SCAR) to identify the questions that matter most for the future of Antarctic and Southern Ocean science.

Ptolemy’s Southern Shore: The Map That Closed an Ocean

For centuries, one of the most influential geographic ideas about the southern hemisphere rested on remarkably thin evidence. Claudius Ptolemy’s world map, based on knowledge compiled in the second century AD and revived during the Renaissance, depicted the Indian Ocean as a vast enclosed sea, bounded to the south by an unknown landmass.

Stormier Ross Sea Winters Raise New Challenges for Antarctic Science

Winter storms in the southern Ross Sea are becoming more frequent and more intense, according to new research from the University of Otago, with implications that extend well beyond meteorology. The findings suggest that changing storm patterns are already affecting sea-ice conditions that underpin scientific operations in one of Antarctica's most important research regions.

When James Cook First Crossed the Antarctic Circle

On 17 January 1773, the two ships became the first known vessels to cross the Antarctic Circle. Commanded by James Cook and Tobias Furneaux, the expedition was searching for the supposed southern continent, but what the sailors encountered instead was a vast, hostile seascape of fog, ice and bitter cold

Ancient Wildfires Shaped Antarctic Peatlands 90 Million Years Ago

Antarctica is synonymous with ice today, but during the Late Cretaceous, around 90 million years ago, the continent looked dramatically different. New research led by scientists from the Alfred Wegener Institute has revealed that wildfires regularly burned in forests growing close to the South Pole, making them the southernmost known wildfires ever identified on Earth.

Half a Century of Satellite Data Reveals Massive Polar Ice Loss

The most comprehensive assessment yet of changes in the world's polar ice sheets, led by researchers from Northumbria University and supported by NASA, combined evidence from 42 independent satellite surveys spanning more than five decades. The findings show that the two ice sheets lost an estimated 11,309 billion tonnes of ice between 1979 and 2023.
