The Western Antarctic Peninsula (WAP) has been experiencing rapid regional warming since at least the 1950s, however, the impacts of this warming at the local scale are variable and nuanced. […]
Meteoroids of sub-milligram sizes burn up high in the Earth’s atmosphere and cause streaks of plasma trails detectable by meteor radars. The altitude at which these trails, or meteors, form […]
The benthic biodiversity of the abyssal Labrador Sea was investigated using Agassiz trawl and in situ imagery. A megafaunal scaphopod associated with an epizoic anemone was recovered from soft sediments. […]
Emission of NOx and HONO from the snowpack can have a significant impact on the oxidising capacity of the boundary layer in the polar regions. This thesis presents work that […]
In aquatic insects, body size and shape are key traits that may indicate phenotypic plasticity or adaptations to their hydrological landscape. Liodessus chilensis is a small and poorly-known aquatic beetle […]
Bottom water formation in the Weddell Sea and mass loss from the Filchner–Ronne Ice Shelf are tightly linked by the supply of Warm Deep Water to the continental shelf. Heavy […]
The climate of the upper atmosphere, including the mesosphere, thermosphere and ionosphere, is changing. As data records are much more limited than in the lower atmosphere and solar variability becomes […]
The Southern Annular Mode (SAM) is an important pattern of Southern Hemisphere circulation variability: it accounts for between 15 and 30 or more percent of the total variability of the […]
Knowledge of how animals respond to weather and changes in their physical environment is increasingly important, given the higher frequency of extreme weather recorded in recent years and its forecasted […]
The increase in iceberg discharge into the polar oceans highlights the importance of understanding how quickly icebergs are deteriorating and where the resulting freshwater injection is occurring. Recent advances in […]
Monitoring the movement of plastic into marine food webs is central to understanding and mitigating the plastic pollution crisis. Bioindicators have been a component of the environmental monitoring toolkit for […]
Protection of specific species, generally through the implementation of an associated action plan, is a conservation tool used commonly in areas under national jurisdiction. The Antarctic Treaty area is under […]
