Per- and polyfluoroalkyl substances (PFAS) are a group of persistent organic contaminants of which some are toxic and bioaccumulative. Several PFAS can be formed from the atmospheric degradation of precursors […]
A high-resolution ocean model is used to characterize the variability of the shelf circulation and cross-shelf transport around the South Georgia island (SG). The time-mean shelf circulation consists of a […]
The lower thermosphere-ionosphere (LTI) is a key transition region between Earth’s atmosphere and space. Interactions between ions and neutrals maximize within the LTI and in particular at altitudes from 100 […]
The use of very high-resolution (VHR) optical satellites is gaining momentum in the field of wildlife monitoring, particularly for whales, as this technology is showing potential for monitoring the less […]
The nutrient-poor soils of Antarctica are sensitive to change. Recent increases in the number of anthropogenic introductions mean that understanding the impact of non-native species on Antarctic soils is pertinent, […]
Auroral zones are regions where, in an average sense, aurorae due to solar activity are most likely spotted. Their shape and, similarly, the geographical locations most vulnerable to extreme space […]
The mesosphere/lower thermosphere (MLT, 80–100 km) region is an important boundary between Earth’s atmosphere below and space above and may act as a sensitive indicator for anthropogenic climate change. Existing […]
A new meteorological dataset derived from records of Antarctic automatic weather stations (here called the AntAWS dataset) at 3 h, daily and monthly resolutions including quality control information is presented here. […]
Understanding ice stream dynamics over decadal to millennial timescales is crucial for improving numerical model projections of ice sheet behaviour and future ice loss. In marine-terminating settings, ice shelves play […]
This chapter describes the best current definitions for nanoplastics in terms of specific origin, size, properties, their behavior in aquatic media, and ecotoxic interactions with other aquatic pollutants and living […]
Antarctic Specially Protected Areas (ASPAs) are a key regulatory mechanism for protecting Antarctic environmental values. Previous evaluations of the effectiveness of the ASPA system have focused on its representativeness and […]
Climate change is increasingly affecting Antarctica and the rest of the world. Urgent policy responses are needed to mitigate its associated impacts. Engagement of the Antarctic Treaty Consultative Meeting (ATCM), […]
