Advances in satellite Earth Observation (EO) have enabled comprehensive and continuous monitoring, and characterisation, of Antarctica and the Southern Ocean. EO data products provide essential information to tackle the scientific […]
Antarctica is changing faster than our current observation networks can robustly assess or predict. Recent extreme events – major ice-shelf collapse, unprecedented heatwaves and abrupt, record-low winter sea ice – […]
Insufficient understanding of the surface energy and mass budgets of the Southern Ocean and Antarctic Continent (SOAC) fundamentally limits our ability to estimate when, how fast and severely the region […]
Antarctica and its surrounding ocean host unique, endemic and cold adapted ecosystems. The Southern Ocean is furthermore, highly productive and provides globally important ecosystem services, from carbon sequestration to substantial […]
Rapid and accelerating changes across the Antarctic Ice Sheet are driven by coupled ice–ocean–atmosphere–solid Earth processes. This impacts sea-level change, ocean circulation and climate feedbacks, all of which remain insufficiently […]
Since 2015, Antarctic sea ice has entered a period of persistent record-low extent after decades of strong regional variability and large swings. The speed and persistence of this decline point […]
Theme 1 addresses the Southern Ocean’s (south of 30°S) critical role in regulating Earth’s climate through circulation patterns that mediate global exchanges of heat, carbon, freshwater, and nutrients. The region […]
At the subantarctic islands of South Georgia, albatrosses and petrels occupy a range of trophic niches, from zooplanktivore to top predator. Interspecific variation in mercury (Hg) contamination is therefore expected […]
The behaviour of ice sheets during ice mass loss is currently not well constrained and is a major limiting factor in accurate predictions of ice sheet behaviour in our warming […]
Antarctica is designated as a natural reserve devoted to peace and science, with Antarctic Specially Protected Areas (ASPAs) serving as the primary instrument for area-based biodiversity protection. However, the existing […]
Antarctica preserves a meagre Mesozoic dinosaur record, with fossils known only from the Lower Jurassic Hanson Formation of the Transantarctic Mountains and Upper Cretaceous units of the James Ross Sub-Basin […]
The complex terrain in mountainous regions makes it extremely difficult to accurately measure or model snowfall, which is a key component of the terrestrial water budget. This study addresses these […]
