Late Miocene onset of hyper-aridity in East Antarctica indicated by meteoric beryllium-10 in permafrost

The hyper-arid climate of modern East Antarctica only arose in the late Miocene, millions of years after the interval of rapid ice-sheet expansion, according to meteoric beryllium-10 concentrations within the permafrost.

Glacial lake outburst floods enhance benthic microbial productivity in perennially ice-covered Lake Untersee (East Antarctica)

Large periodic glacial outburst flood events replenish inorganic carbon concentrations and fuel the primary productivity of benthic microbial communities in the perennially ice-covered Lake Untersee.

Synthetic aperture radar backscatter is influenced by bubbles at the ice/water interface of an Antarctic lake

The number of small bubbles at the ice-water interface in a perennially ice-covered lake varies in response to changes in ice thickness leading to seasonal variations in the backscatter detected by synthetic aperture radar, suggests 4-year observational time series from Lake Untersee, Antarctica.

Improved prediction of the vertical distribution of ground ice in Arctic-Antarctic permafrost sediments

Frost susceptibility of permafrost sediments is strongly influenced by unfrozen water content, which is dependent on sediment type, soil water chemistry, and temperature, according to field observations and ensemble modeling prediction of ground ice formation in Arctic-Antarctic sediments.
