The crystal orientation fabric of glacier ice impacts its strength and flow. Crystal fabric is therefore an important consideration when modelling ice flow. Here, we show that shear-wave splitting (SWS) […]
The removal of carbon from the atmosphere for a long period (sequestration) is an increasingly pressing societal need in order to mitigate the negative effects of climate change. Investment and […]
Natural aerosols and their interactions with clouds remain an important uncertainty within climate models, especially at the poles. Here, we study the behavior of sea salt aerosols (SSaer) in the […]
Plasmaspheric hiss is an electromagnetic wave mode that occurs ubiquitously in the high-density plasmasphere and contributes crucially to the dynamic behavior of the Earth’s Van Allen radiation belts. While plasmaspheric […]
We calculate a regional surface “melt potential” index (MPI) over Antarctic ice shelves that describes the frequency (MPI-freq, %) and intensity (MPI-int, K) of daily maximum summer temperatures exceeding a […]
The germline mutation rate determines the pace of genome evolution and is an evolving parameter itself. However, little is known about what determines its evolution, as most studies of mutation […]
Antarctic soils provide an excellent setting to test biogeographical patterns across spatial and environmental scales given their relatively simple communities and the dominance of physical factors that create strong environmental […]
Mapping spatiotemporal changes in the distribution of blue ice regions (BIRs) in Antarctica requires repeated, precise, and high-resolution baseline maps of the blue ice extent. This study demonstrated the design […]
Meaningful protection of global oceans lags far behind that of land and has taken little consideration of climate mitigation potential to date (such as through assessment of blue carbon stocks […]
Assessing environmental changes in Southern Ocean ecosystems is difficult due to its remoteness and data sparsity. Monitoring marine predators that respond rapidly to environmental variation may enable us to track […]
Los impactos del cambio climático están afectando fuertemente los ecosistemas, comunidades y especies terrestres y acuáticas de las regiones polares y subpolares. La ecorregión subantártica de Magallanes, debido a sus […]
Free-living terrestrial mites (Acari) have persisted through numerous glacial cycles in Antarctica. Very little is known, however, of their genetic diversity and distribution, particularly within the Ross Sea region. To […]
