Arctic sea ice is projected to thin and reduce in extent significantly over the next century. Both sea ice and its overlying snow limit the amount of light that reaches […]
Cryptotephra (non-visible volcanic ash) deposits in the Falkland Islands (Islas Malvinas) provide a distal record of South American volcanism and ash dispersal into the South Atlantic Ocean. Here, we present […]
This work aims to characterize the ionospheric disturbances in the South America – Antarctic Peninsula sector due the impact of a X1.3 solar event. This flare occurred on 30 March […]
The Amundsen Sea is dominated by a quasi-stationary low-pressure region, the Amundsen Sea Low (ASL). ASL variability impacts on regional weather and the basal melting of ice shelves, an important […]
Understanding the risk of introduction of marine non-native species requires data on pathways, including the level of biofouling present on vessels, vessel operating profiles and maintenance regimes. This study presents […]
Peter Fretwell is a senior scientist in the Mapping and Geographic Information Centre, at the British Antarctic Survey. Peter has pioneered the use of satellite imagery to study polar wildlife […]
Antarctic krill (Euphausia superba) is the central prey species in the Southern Ocean food web, supporting the largest and fastest-growing fishery in the region, managed by the Commission for the […]
A quarter of all marine methane, a potent greenhouse gas, is estimated to be hosted in Southern Ocean sediments. Climate change-induced ocean warming and ice shelf melting risk the stability […]
Numerous evaporative saline playa lakes exist within the Thar Desert in Northwest India. Some are active seasonally, whereas others are dry and preserve up to several meters of sedimentary deposits. […]
Climate change is inducing a global atmospheric contraction above the tropopause (~10 km), leading to systematic decrease in neutral air density. The impact of climate change on small meteoroids has […]
Fossil-fuel burning is heating the planet with catastrophic consequences for its habitability and for the natural world on which our existence depends. Halting global warming requires rapid and deep decarbonization […]
To date, environmental conditions have been enough to act as an effective barrier to prevent non-indigenous species from arriving and establishing in Arctic Canada. However, rapidly changing climatic conditions are […]
