1. Antarctica as a ‘natural laboratory’ for the critical assessment of the archaeological validity of early stone tool sites

   Lithic technologies dominate understanding of early humans, yet natural processes can fracture rock in ways that resemble artefacts made by Homo sapiens and other primates. Differentiating between fractures made by […]

2. Levels and distribution profiles of Per- and Polyfluoroalkyl Substances (PFAS) in a high Arctic Svalbard ice core

   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 […]

3. Variability of the shelf circulation around South Georgia, Southern Ocean

   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 […]

4. Plasma-neutral interactions in the lower thermosphere-ionosphere: The need for in situ measurements to address focused questions

   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 […]

5. Annotating very high-resolution satellite imagery: A whale case study

   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 […]

6. Ecological consequences of a single introduced species to the Antarctic: Terrestrial impacts of the invasive midge Eretmoptera murphyi on Signy Island

   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, […]

7. Climatological predictions of the auroral zone locations driven by moderate and severe space weather events

   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 […]

8. Solar Cycle and Long‐Term Trends in the Observed Peak of the Meteor Altitude Distributions by Meteor Radars

   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 […]

9. The AntAWS dataset: a compilation of Antarctic automatic weather station observations

   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. […]

10. The geomorphological record of an ice stream to ice shelf transition in Northeast Greenland

    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 […]

11. Nanoplastics in Urban Waters: Recent Advances in the Knowledge Base

    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 […]

12. Evaluating the conservation impact of Antarctica’s protected areas

    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 […]
