Hepatophytes form an important component of the Lower Cretaceous (late Albian) flora of Alexander Island, Antarctica. The liverworts Marchantites rosulatus sp. nov., Thallites bicostatus sp. nov., and Thallites sp. colonized […]
We present two time series of bottom current and temperature collected 8 m above the seabed on either side of a large sediment drift located on the continental rise of […]
Ocean waters melt the margins of Antarctic and Greenland glaciers, and individual glaciers’ responses and the integrity of their ice shelves are expected to depend on the spatial distribution of […]
To fully understand the Holocene climatic variability in the sub-polar latitudes of the Southern Hemisphere and its driving mechanisms, like the Southern Hemisphere westerly winds, we undertook a multi-proxy analysis […]
The Last Interglacial (LIG, 129–116 thousand of years BP, ka) represents a test bed for climate model feedbacks in warmer-than-present high latitude regions. However, mainly because aligning different palaeoclimatic archives […]
Ice cores contain a record of snow precipitation that includes information about past atmospheric circulation and mass imbalance in the polar regions. We present a novel adjoint method to reconstruct […]
We use National Centers for Environmental Prediction/National Center for Atmospheric Research reanalysis data to estimate the altitude and time lag dependence of the correlation between the interplanetary magnetic field component, […]
Wave particle interactions play an important role in controlling the dynamics of the radiation belts. The purpose of this study is to estimate how variations in the plasma density can […]
