Ground‐based observations of VLF waves as a proxy for satellite observations: Development of models including the influence of solar illumination and geomagnetic disturbance levels
Read more of: Ground‐based observations of VLF waves as a proxy for satellite observations: Development of models including the influence of solar illumination and geomagnetic disturbance levelsGround VLF observations have often been used to infer VLF activity in the magnetosphere, however, they are not an unbiased measure of activity at satellite altitudes due to transionospheric absorption […]

Relative paleointensity (RPI) and age control in Quaternary sediment drifts off the Antarctic Peninsula
Read more of: Relative paleointensity (RPI) and age control in Quaternary sediment drifts off the Antarctic PeninsulaLack of foraminiferal carbonate in marine sediments deposited at high latitudes results in traditional oxygen isotope stratigraphy not playing a central role in Quaternary age control for a large portion […]

Moho depths of Antarctica: comparison of seismic, gravity, and isostatic results
Read more of: Moho depths of Antarctica: comparison of seismic, gravity, and isostatic resultsThe lithospheric structure of Antarctica is still under‐explored. Moho depth estimate studies are in disagreement by more than 10 km in several regions, including for example the hinterland of the […]

Status and trends of terrestrial arthropod abundance and diversity in the North Atlantic region of the Arctic
Read more of: Status and trends of terrestrial arthropod abundance and diversity in the North Atlantic region of the ArcticThe Circumpolar Biodiversity Monitoring Programme (CBMP) provides an opportunity to improve our knowledge of Arctic arthropod diversity, but initial baseline studies are required to summarise the status and trends of […]

Comparison of short period TID morphologies in Antarctica during geomagnetically quiet and active intervals
Read more of: Comparison of short period TID morphologies in Antarctica during geomagnetically quiet and active intervalsTravelling ionospheric disturbances with periods in the range 10 < τ < 30 min were observed by an HF Doppier network on the Antarctic Peninsula. A distinction was made between […]

Antarctic terrestrial ecosystems
Read more of: Antarctic terrestrial ecosystemsThe Maritime and Continental Antarctic terrestrial ecosystems are considered in the context of environmental impacts-habitat destruction, alien introductions, and pollution. Their ability to recover from perturbation is discussed in the […]

The status and conservation of Antarctic seals and seabirds: A review
Read more of: The status and conservation of Antarctic seals and seabirds: A reviewPresent threats to Antarctic seabirds and seals when ashore include disturbance and habitat destruction (some directly caused by humans; most through the introduction of rabbits and other grazers; also seal […]
