1. Seabird and seal responses to the physical environment and to spatio-temporal variation in the distribution and abundance of Antarctic krill at South Georgia, with implications for local fisheries management

   We used 22 years of seasonally and spatially consistent monitoring data to explore marine predator–prey numerical response relationships. Specifically, we tested whether indices of offspring performance (e.g. offspring mass near the […]

2. Influence of marine vertebrates on organic matter, phosphorus and other chemical element levels in Antarctic soils

   The presence of marine vertebrates in dense reproductive colonies and other aggregations contributes to the input of organic matter and nutrients into the local environment and it is believed that […]

3. Temporal variability of quasilinear pitch-angle diffusion

   Kinetic wave-particle interactions in Earth’s outer radiation belt energize and scatter high-energy electrons, playing an important role in the dynamic variation of the extent and intensity of the outer belt. […]

4. Animal survival strategies in Neoproterozoic ice worlds

   The timing of the first appearance of animals is of crucial importance for understanding the evolution of life on Earth. Although the fossil record places the earliest metazoans at 572–602 Ma, […]

5. The Antarctic contribution to 21st-century sea-level rise predicted by the UK Earth System Model with an interactive ice sheet

   The Antarctic Ice Sheet will play a crucial role in the evolution of global mean sea level as the climate warms. An interactively coupled climate and ice sheet model is […]

6. Geomagnetic disturbances that cause GICs: investigating their interhemispheric conjugacy and control by IMF orientation.

   Nearly all studies of impulsive geomagnetic disturbances (GMDs, also known as magnetic perturbation events MPEs) that can produce dangerous geomagnetically induced currents (GICs) have used data from the northern hemisphere. […]

7. Aerobiology over the Southern Ocean – Implications for bacterial colonization of Antarctica

   Parts of the Antarctic are experiencing dramatic ecosystem change due to rapid and record warming, which may weaken biogeographic boundaries and modify dispersal barriers, increasing the risk of biological invasions. […]

8. Determining the origin of tidal oscillations in the ionospheric transition region with EISCAT radar and global simulation data

   At high-latitudes, diurnal and semidiurnal variations of temperature and neutral wind velocity can originate both in the lower atmosphere (UV or infrared absorption) or in the thermosphere-ionosphere (ion convection, EUV […]

9. Ocean variability beneath the Filchner‐Ronne Ice Shelf inferred from basal melt rate time series

   Fourteen phase-sensitive radars (ApRES) were deployed on the Filchner-Ronne Ice Shelf (FRIS) to measure variability in its basal melt rate. Melt rates from sites along the Ronne Depression vary seasonally, […]

10. Tunnel valley formation beneath deglaciating mid-latitude ice sheets: Observations and modelling

    The geological record of landforms and sediments produced beneath deglaciating ice sheets offers insights into inaccessible glacial processes. Large subglacial valleys formed by meltwater erosion of sediments (tunnel valleys) are […]

11. Ancient marine sediment DNA reveals diatom transition in Antarctica

    Antarctica is one of the most vulnerable regions to climate change on Earth and studying the past and present responses of this polar marine ecosystem to environmental change is a […]

12. Responding to warming in polar oceans: A commentary on Molina et al. (2022)

    Antarctic marine species live in one of the most thermally stable environments on Earth. They have evolved in these cold stable conditions for many millions of years. The long period […]
