1. Changing circumpolar distributions and isoscapes of Antarctic krill: Indo‐Pacific habitat refuges counter long‐term degradation of the Atlantic sector

   The Southern Ocean provides strong contrasts in rates and directions of change in temperature and sea ice between its sectors, but it is unknown how these affect plankton species that […]

2. Long-term changes in habitat and trophic level of Southern Ocean squid in relation to environmental conditions

   Long-term studies of pelagic nekton in the Southern Ocean and their responses to ongoing environmental change are rare. Using stable isotope ratios measured in squid beaks recovered from diet samples […]

3. Forecasting extreme stratospheric polar vortex events

   Extreme polar vortex events known as sudden stratospheric warmings can influence surface winter weather conditions, but their timing is difficult to predict. Here, we examine factors that influence their occurrence, […]

4. The effectiveness of Virkon® S disinfectant against the invasive chironomid Eretmoptera murphyi and implications for Antarctic biosecurity practices

   The flightless midge Eretmoptera murphyi is thought to be continuing its invasion of Signy Island via the treads of personnel boots. Current boot-wash biosecurity protocols in the Antarctic region rely […]

5. Zircon O and Hf isotope constraints on the genesis of Permian–Triassic magmatic and metamorphic rocks in the Antarctic Peninsula and correlations with Patagonia

   The Permian–Triassic is a critical period for interpreting and understanding the development of West Antarctica and its correlations into Patagonia, South America. The Antarctic Peninsula preserves isolated outcrops of Permian–Triassic […]

6. Gene flow in the Antarctic bivalve Aequiyoldia eightsii (Jay, 1839) suggests a role for the Antarctic Peninsula Coastal Current in larval dispersal

   The Antarctic Circumpolar Current (ACC) dominates the open-ocean circulation of the Southern Ocean, and both isolates and connects the Southern Ocean biodiversity. However, the impact on biological processes of other […]

7. Inbreeding depresses altruism in a cooperative society

   In some animal species, individuals regularly breed with relatives, including siblings and parents. Given the high fitness costs of inbreeding, evolutionary biologists have found it challenging to understand the persistence […]

8. Estimating circumpolar distributions of lanternfish using 2D and 3D ecological niche models.

   Ecological niche models (ENMs) can be a practical approach for investigating distributions and habitat characteristics of pelagic species. In principle, to reflect the ecological niche of a species well, ENMs […]

9. Depth-dependent artifacts resulting from ApRES signal clipping

   Several autonomous phase-sensitive radio-echo sounders (ApRES) were deployed at Greenland glaciers to investigate ice deformation. Different attenuation settings were tested and it was observed that, in the presence of clipping […]

10. Calibration of shell δ18O from the common whelk Buccinum undatum highlights potential for environmental reconstruction

    The common whelk, Buccinum undatum, is a commercially important gastropod found throughout the North Atlantic. One method of age and life history analysis for gastropod species is the use of […]

11. A synthesis of thermodynamic ablation at ice–ocean interfaces from theory, observations and models.

    Thermodynamic ablation of ice in contact with the ocean is an essential element of ice sheet and ocean interactions but is challenging to model and quantify. Building on earlier observations […]
