Ice-rise stratigraphy reveals changes in surface mass balance over the last millennia in Dronning Maud Land
Read more of: Ice-rise stratigraphy reveals changes in surface mass balance over the last millennia in Dronning Maud LandWe use ice flow modelling to simulate the englacial stratigraphy of Blåskimen Island, an ice rise in Dronning Maud Land and elucidate the evolution of this data-sparse region. We apply […]

Basal freeze-on generates complex ice-sheet stratigraphy
Read more of: Basal freeze-on generates complex ice-sheet stratigraphyLarge, plume-like internal ice-layer-structures have been observed in radar images from both Antarctica and Greenland, rising from the ice-sheet base to up to half of the ice thickness. Their origins […]

Earth tectonics as seen by GOCE – Enhanced satellite gravity gradient imaging
Read more of: Earth tectonics as seen by GOCE – Enhanced satellite gravity gradient imagingCurvature components derived from satellite gravity gradients provide new global views of Earth’s structure. The satellite gravity gradients are based on the GOCE satellite mission and we illustrate by curvature […]

Niche partitioning of sympatric penguins by leapfrog foraging is resilient to climate change
Read more of: Niche partitioning of sympatric penguins by leapfrog foraging is resilient to climate change1.Interspecific competition can drive niche partitioning along multidimensional axes, including allochrony. Competitor matching will arise where the phenology of sympatric species with similar ecological requirements respond to climate change at […]

Holocene glacier fluctuations and environmental changes in sub-Antarctic South Georgia inferred from a sediment record from a coastal inlet
Read more of: Holocene glacier fluctuations and environmental changes in sub-Antarctic South Georgia inferred from a sediment record from a coastal inletThe sub-Antarctic island of South Georgia provides terrestrial and coastal marine records of climate variability, which are crucial for the understanding of the drivers of Holocene climate changes in the […]

Impact of preservation techniques on pteropod shell condition
Read more of: Impact of preservation techniques on pteropod shell conditionPteropods have been a key focus of ocean acidification studies during the last decade due to their fragile aragonite shells and key role they play in polar ecosystems. Pteropods collected […]
