The waters surrounding the South Orkney Islands have emerged as an important hotspot for recovering whale populations, prompting Antarctic tour operators to introduce a new vessel-speed restriction aimed at reducing the risk of ship strikes.

The Mackenzie Polynya, an area of open water or thin ice that persists within the surrounding winter sea-ice pack, forms in Prydz Bay. Although they may appear to be small gaps in the Antarctic sea-ice cover, polynyas play an outsized role in the Southern Ocean system. They are major sites of sea-ice formation, contributing to the production of dense, cold water that helps drive global ocean circulation.

Hidden beneath nearly four kilometres of Antarctic ice, Lake Vostok is one of the planet’s most extraordinary scientific targets. Isolated from the atmosphere for millions of years, the vast subglacial lake may preserve a unique record of Antarctica’s environmental history in the sediments that lie on its floor.
This annual seasonal transition highlights a growing trend in polar science: the increasing role of autonomous technologies in collecting data from regions where year-round human occupation is costly and difficult. Instruments left behind can continue monitoring atmospheric conditions, glaciological processes and other environmental variables long after field teams have returned home.
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).

Scientists in Australia are unlocking atmospheric secrets preserved deep within Antarctic ice, refining techniques that could eventually reveal how Earth's climate behaved more than one million years ago.

One of the most significant achievements of the First French Antarctic Expedition was the systematic survey of the western Antarctic Peninsula, including parts of Graham Land and the Palmer Archipelago.

The Antarctic coast is far more than the continent’s outer edge. It is a dynamic region where grounded ice, floating ice shelves, ocean waters, the atmosphere and the underlying geology interact. Changes in this narrow zone can influence how quickly ice flows into the ocean and, ultimately, how much Antarctica contributes to global sea level rise.

Antarctica has no continent-wide rescue service waiting to respond to emergencies. Instead, search and rescue operations depend on a network of national Antarctic programmes, government agencies, ships, aircraft operators and rescue coordination centres working together across enormous distances.

More than 120 years after the Scottish National Antarctic Expedition sailed south aboard Scotia, new digital resources are helping bring one of the Heroic Age’s most significant scientific voyages to life.

The presence of diatoms (microscopic algae that thrive in sunlit ocean waters) suggests that the area was once an open marine environment rather than being permanently covered by an ice shelf. If confirmed through further analysis, the findings would provide direct evidence that the Ross Ice Shelf collapsed and parts of the West Antarctic Ice Sheet retreated during warmer periods in Earth's past.
