2. 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 […]

3. 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 […]

4. 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 […]

5. 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 (

6. South Georgia blue whales five decades after the end of whaling

   Blue whales Balaenoptera musculus at South Georgia were heavily exploited during 20th century industrial whaling, to the point of local near-extirpation. Although legal whaling for blue whales ceased in the […]

7. Miocene to present oceanographic variability in the Scotia Sea and Antarctic Ice Sheet dynamics: Insight from revised seismic-stratigraphy following IODP Expedition 382

   Scotia Sea and the Drake Passage is key towards understanding the development of modern oceanic circulation patterns and their implications for ice sheet growth and decay. The sedimentary record of […]

8. Seafloor depth of George VI Sound, Antarctic Peninsula, from inversion of aerogravity data

   George VI Sound is a ~600 km long curvilinear channel on the west coast of the southern Antarctic Peninsula separating Alexander Island from Palmer Land. The Sound is a geologically […]

9. Improved phase-field models of melting and dissolution in multi-component flows

   We develop and analyse the first second-order phase-field model to combine melting and dissolution in multi-component flows. This provides a simple and accurate way to simulate challenging phase-change problems in […]

10. Observed eddy-internal wave interactions in the Southern Ocean

    The physical mechanisms that remove energy from the Southern Ocean’s vigorous mesoscale eddy field are not well understood. One proposed mechanism is direct energy transfer to the internal wave field […]

11. The dynamics of the South Pacific split jet in austral winter

    The wintertime atmospheric circulation in the southern hemisphere is characterised by a zonally asymmetric, spiral-like pattern. This includes a strong jet over the Indian Ocean region, which bifurcates downstream into […]

12. Recent recovery of Antarctic Bottom Water formation in the Ross Sea driven by climate anomalies

    Antarctic Bottom Water (AABW) supplies the lower limb of the global overturning circulation, ventilates the abyssal ocean and sequesters heat and carbon on multidecadal to millennial timescales. AABW originates on […]
