South Georgia forms one of the most isolated fragments of continental crust on Earth and lies in a remote location in the Southern Ocean. Its geology is dominated by Early […]
This report presents outcomes from the international workshop “Essential Biodiversity Variables (EBV) Framework for Terrestrial Antarctic and Sub-Antarctic Ecosystems,” held in Cambridge, UK, from 18–20 September 2024, with significant online […]
Diversity, distribution and biogeographical aspects of polar macroalgae must be reassessed as they face contemporary environmental changes. Macroalgae are the basis of the marine food web, efficient carbon sinks, biogenic […]
Relativistic electrons are an important space weather hazard, being a major source of radiation damage to satellites and posing a risk to humans in space. We use approximately 20 years […]
Numerical age models are useful tools for investigating the age of the ice in an ice sheet. They can be used to date ice cores or to interpret isochronal horizons […]
Marine megafauna species are affected by a wide range of anthropogenic threats. To evaluate the risk of such threats, species’ vulnerability to each threat must first be determined. We build […]
The emergence of highly pathogenic avian influenza viruses (HPAIV) has caused widespread mortality wildlife globally. In 2023, mass mortalities of southern elephant seals Mirounga leonina were observed in South America, […]
As sea ice retreats in a warming climate, the Arctic Ocean is becoming more energetic; yet little is known about this additional energy’s distribution in the water column. We use […]
Coupled with the Antarctic Slope Front (ASF), the Antarctic Slope Current (ASC) mostly encircles Antarctica and has variable structures. Two regimes of the ASC/ASF have been identified in the Ross […]
Tourism in Antarctica is increasing rapidly and is concentrated predominantly in ice-free areas in the Antarctic Peninsula region, an area that holds globally important colonies of breeding birds. Since 2005, […]
