1. Inhibitory effects of climate change on the growth and extracellular enzyme activities of a widespread Antarctic soil fungus

   Temperatures approaching or exceeding 20 °C have been measured during summer in polar regions at the surfaces of barren fellfield soils under cloudless skies around solar noon. However, despite the […]

2. Assessment of the effects of isolation, confinement and hypoxia on spaceflight piloting performance for future space missions – The SIMSKILL experiment in Antarctica

   Interplanetary human missions to Mars and beyond will suppose a very demanding physical and psychological environment for future astronauts. Isolation, confinement, hypoxia or hypercapnia in a less pressurized atmosphere, darkness […]

3. Glacial dynamics and deglaciation history of Hambergbukta reconstructed from submarine landforms and sediment cores, SE Spitsbergen, Svalbard

   The submarine landforms and shallow sediment record are presented from Hambergbukta, southeastern Spitsbergen using swath‐bathymetric, subbottom acoustic, and sediment core data. The mapped landforms include large terminal and end‐moraines with […]

4. Marine ecosystem assessment for the Southern Ocean: birds and marine mammals in a changing climate

   The massive number of seabirds (penguins and procellariiformes) and marine mammals (cetaceans and pinnipeds) – referred to here as top predators – is one of the most iconic components of […]

5. The role of curvature in modifying frontal instabilities. Part I: Review of theory and presentation of a nondimensional instability criterion

   In this study, we examine the role of curvature in modifying frontal stability. We first evaluate the classical criterion that the Coriolis parameter, f, multiplied by the Ertel potential vorticity […]

6. The role of curvature in modifying frontal instabilities. Part II: Application of the criterion to curved density fronts at low Richardson numbers

   We continue our study of the role of curvature in modifying frontal stability. In Part 1, we obtained an instability criterion valid for curved fronts and vortices in gradient wind […]

7. Reconciling the surface temperature–surface mass balance relationship in models and ice cores in Antarctica over the last 2 centuries

   Ice cores are an important record of the past surface mass balance (SMB) of ice sheets, with SMB mitigating the ice sheets’ sea level impact over the recent decades. For […]

9. Implications of the COVID-19 pandemic for Antarctica

   To date, Antarctica is the only continent to have escaped the COVID-19 pandemic. This was facilitated by the continent’s isolation and low human presence, combined with the global emergence of […]

10. Alpha transmitter signal reflection and triggered emissions

    Russian Alpha radio navigation system (RSDN‐20) emits F1=11.9kHz signals into the magnetosphere which propagate as whistler‐mode waves. Observed by waveform continuous burst mode from EMFISIS on Van Allen Probes, a […]

11. Analysis and attribution of climate change in the upper atmosphere from 1950 to 2015 simulated by WACCM-X

    Monitoring climatic changes in the thermosphere and ionosphere and understanding their causes is important for practical purposes. To support this effort and facilitate comparisons between observations and model results, a […]

12. Unequal anthropogenic enrichment of mercury in Earth’s Northern and Southern Hemispheres

    Remote Northern Hemisphere (NH) and Southern Hemisphere (SH) lake sediment and peat records of mercury (Hg) deposition have shown a ×3 to ×5 Hg enrichment since pre-industrial times (
