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.

At China’s Zhongshan Station in East Antarctica, aircraft operating during the 2025-26 season relied on a carefully prepared strip of compacted snow marked by flags and governed by constantly changing weather conditions.

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.
A major new study has produced the most comprehensive inventory yet of volcanoes concealed beneath Antarctica's ice sheet, providing researchers with an important new tool for understanding how geological processes may influence the future behaviour of the Antarctic Ice Sheet.
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
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.
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.

A vast geological structure hidden beneath the East Antarctic Ice Sheet is offering scientists a new way to understand both Antarctica’s ancient past and the behaviour of its ice today. The findings may help explain events linked to the evolution of the supercontinent Gondwana and the eventual separation of Antarctica from Australia.

Hundreds of circular seafloor features have been found on the sea bed of the Ross Sea, at depths of between 300 and 1,200 meters. Their origin remains uncertain, making them one of Antarctica's more intriguing geological puzzles. Early hypotheses range from fluid or gas-related processes to the interaction of oceanographic and sedimentary forces over long timescales.

Satellite monitoring of emperor penguin colonies across Antarctica has strengthened evidence that the species faces mounting pressure as warming temperatures alter the habitat on which it depends. However, a proposal to designate the emperor penguin as an Antarctic Specially Protected Species failed to secure consensus at this year's Antarctic Treaty Consultative Meeting (ATCM).

A unique satellite experiment has provided scientists with a rare opportunity to compare Antarctic ice movement across a span of three decades. The result is an unusually direct comparison of how parts of Antarctica have evolved over the last 30 years.

When most people think about ocean carbon uptake, they picture microscopic plants near the sea surface using sunlight to convert carbon dioxide into organic matter through photosynthesis. However, new research suggests that microorganisms living deep beneath the Ross Sea are helping to capture carbon in complete darkness.

During the 2025-26 Antarctic summer season, the international IceCube collaboration completed a major upgrade of the IceCube Neutrino Observatory at the South Pole. The new equipment is expected to improve the observatory’s ability to detect low-energy neutrinos, elusive particles that can travel across the cosmos largely unaffected by matter.
