1. Diatom–environment relationships and limnological variability: an updated quantitative tool for palaeoclimatology on sub-Antarctic Macquarie Island

   Sub-Antarctic Macquarie Island is ideally located for reconstructing past variations in Southern Hemisphere westerly wind strength. Diatoms are a valuable palaeolimnological tool on sub-Antarctic islands, providing a means to reconstruct […]

2. Atmospheric 10 Be from Talos Dome (East Antarctic) ice core records geomagnetic dipole intensity from 170 to 270 ka BP

   We present high-resolution 10Be concentration and flux records from the Talos Dome ice core (East Antarctica), covering the period from 170 to 270 ka BP, to assess the capacity of Antarctic ice […]

3. Modified fin morphology in mackerel icefish (Champsocephalus gunnari) may indicate nesting behaviour [Brief communication]

   Monitoring reproductive traits in Southern Ocean species is challenging. Males in some channichthyids thicken the epithelium along their anal fins to aid nest construction. This study presents initial evidence that […]

4. From Carbon to Plastics: Partitioning of Biogeochemical and Anthropogenic Particles in Penguin Guano

   Penguins are emblematic inhabitants of the Antarctic continent and play a significant role in the biogeochemical cycles of the Southern Ocean by transferring essential nutrients to marine ecosystems via guano […]

5. Windblown Diatoms for Reconstructing Westerly Wind Variability in the South Atlantic Sector of the Southern Ocean

   Southern Hemisphere westerly winds are important drivers of Antarctic and sub-Antarctic environmental change. Short observational wind records prevent us from fully understanding the scope of their variability. Proxy records provide […]

6. Geomagnetically Induced Currents, Transformer Harmonics, and Reactive Power Impacts: Observed Response of a Single‐Phase Transformer in New Zealand

   Geomagnetic storms represent a space weather hazard to power transmission networks due to the effects of induced geo-electric fields within the conducting surface of the Earth. These drive electric currents […]

7. Evolution of NWC Transmitter Wave Power Distribution From the Topside Ionosphere Into the Inner Magnetosphere

   Ground-based very low frequency transmitters emit signals that primarily propagate within the Earth–ionosphere waveguide, and some of their energy can propagate into the magnetosphere. Ionospheric observations from the DEMETER satellite […]

8. Ice‐Sheet–Ocean Interactions and the Reversibility of a Regime Shift Beneath Filchner‐Ronne Ice Shelf

   Future atmospheric warming could cause an abrupt increase in ocean temperature beneath the Filchner–Ronne Ice Shelf, Antarctica, from −2.2°C to more than 0°C in a few decades. In simulations, such […]

9. Projected and historical amplification of moisture fluxes towards Antarctica by synoptic eddies

   Synoptic weather systems play a crucial role in transporting moisture to Antarctica. Climate models project significant changes in these systems, including a wintertime intensification and a summertime poleward shift, with […]

10. Assessing the Likelihood of Unprecedented Antarctic Heat in the Current Climate

    East Antarctica experienced two recent heatwaves with no historical precedent, in March 2022 in Wilkes Land (WL), and July–August 2024 in Dronning Maud Land (DML). In this study, a large […]

11. Oceanographic influences and high productivity recorded in a coastal bay of the Amundsen Sea, West Antarctica, during the Holocene

    Reconstructing environmental changes near ice margins that have deglaciated since the Last Glacial Maximum (LGM) is essential for understanding future changes of the Antarctic Ice Sheet. Here, we conducted a […]

12. Multidecadal preindustrial methane variability can be explained by noise in the source–sink imbalance

    Ice core records of preindustrial methane indicate variability of ± 30 ppb ( ± 5%) on multidecadal-to-centennial timescales. Previous work has attributed these excursions to low-frequency or episodic changes in […]
