Anomalous freshwater fluxes from the Greenland and Antarctic ice sheets and ice shelves are impacting the surrounding oceans, and we need to be able to account for these effects in […]
Ocean-driven melting of floating ice shelves is currently the main process controlling Antarctica’s contribution to sea level rise. However, despite major advances in the study of ice shelf-ocean interaction over […]
The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) adopted a work program (2019–2030) that included, under its first objective, the interlinkages between biodiversity and climate change (IPBES, 2019). […]
Dryas octopetala is one of the most important botanical components of Arctic tundra. In parts of the Norwegian High Arctic Archipelago of Svalbard it can face strong grazing pressure, in […]
This policy brief summarizes for policymakers the extensive assessment contained in the peer-reviewed paper Siegert et al., 2025 “Safeguarding the polar regions from dangerous geoengineering: a critical assessment of proposed […]
Continuous moored time series of temperature, salinity, pressure and current speed and direction are of great importance for understanding the continental shelf and under-ice-shelf dynamics and thermodynamics that govern water […]
The Mekong River is experiencing dramatic hydrological and sediment transport changes, largely due to the development of hydropower dams, both on its mainstream and tributaries. We ask, “how well do […]
Plastic pollution has reached the remote terrestrial ecosystems of Antarctica, but the extent to which microplastics are affecting native terrestrial invertebrates has not been assessed. Using Antarctica’s only endemic insect, […]
Dielectric anisotropy in ice alters the propagation of polarized radio waves, so polarimetric radar sounding can be used to survey anisotropic properties of ice masses. Ice anisotropy is either intrinsic, […]
On 15 February 2018 a co-rotating interaction region (CIR) from an equatorial coronal hole reached the Earth. The CIR initiated a moderate and slowly intensifying geomagnetic storm, which began with […]
Radio-echo sounding (RES) has revealed an internal architecture within both the West and East Antarctic ice sheets that records their depositional, deformational and melting histories. Crucially, RES-imaged internal-reflecting horizons, tied […]
