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 […]
Observing winter processes during the extended cold season is crucial not only for understanding polar and global coupled Earth system but also for enhancing capability of year-round prediction, especially in […]
Climate variability during the last 60,000 years exhibited pronounced fluctuations on glacial-interglacial to sub-orbital timescales, yet fundamental questions remain regarding the timing, phasing, and cyclical structure of global climate fluctuations. […]
The Foundation-Patuxent-Academy system (FPAS) is a major Antarctic ice stream system, draining both East and West Antarctica, with a global sea level potential of ∼3 m. We provide a holistic catchment-scale […]
Mesoscale eddies are rotating vortices of water that perturb the local physical, chemical, and biological environment. In the Southern Ocean, penguins inhabit regions characterised by intense eddy activity, which can […]
The Guiana coastline, stretching for 1500 km between the Amazon and Orinoco Rivers in South America, is one of the most dynamic shorelines in the world. The shoreline is characterised […]
Invasional meltdown, where interactions between non‐native species amplify their community‐level impacts, is often evidenced through relatively weak cases in which one invader directly benefits another. However, stronger evidence for invasional […]
