Basal roughness of the Institute and Möller Ice Streams, West Antarctica: Process determination and landscape interpretation
Read more of: Basal roughness of the Institute and Möller Ice Streams, West Antarctica: Process determination and landscape interpretationWe present a detailed analysis of bed roughness beneath Institute and Möller Ice Streams, west Antarctica, using radio-echo sounding data (RES) acquired in the austral summer of 2010/11. We assess […]

The relationship between sticky spots and radar reflectivity beneath an active West Antarctic ice stream
Read more of: The relationship between sticky spots and radar reflectivity beneath an active West Antarctic ice streamIsolated areas of high basal drag, or ‘sticky spots’, are important and poorly understood features in the force balance and dynamics of West Antarctic ice streams. Characterizing sticky spots formed […]

Similarity of organized patterns in driving and basal stresses of Antarctic and Greenland ice sheets beneath extensive areas of basal sliding
Read more of: Similarity of organized patterns in driving and basal stresses of Antarctic and Greenland ice sheets beneath extensive areas of basal slidingThe rate of ice transport from the interior of ice sheets to their margins, and hence the rate with which it contributes to sea level, is determined by the balance […]

On the Seasonal Signal of the Filchner Overflow, Weddell Sea, Antarctica
Read more of: On the Seasonal Signal of the Filchner Overflow, Weddell Sea, AntarcticaThe cold ice shelf water (ISW) that formed below the Filchner–Ronne Ice Shelf in the southwestern Weddell Sea, Antarctica, escapes the ice shelf cavity through the Filchner Depression and spills […]

Geometric and oceanographic controls on melting beneath Pine Island Glacier
Read more of: Geometric and oceanographic controls on melting beneath Pine Island GlacierObservations beneath the floating section of Pine Island Glacier have revealed the presence of a subglacial ridge which rises up to 300 m above the surrounding bathymetry. This topographic feature […]

Heating up the Holocene
Read more of: Heating up the HoloceneWith direct meteorological data on the Antarctic Peninsula only dating back to the 1950s, scientists must search elsewhere for climate change records of the distant past. A series of expeditions […]

Morphotypes of virus-like particles in two hydrothermal vent fields on the East Scotia Ridge, Antarctica
Read more of: Morphotypes of virus-like particles in two hydrothermal vent fields on the East Scotia Ridge, AntarcticaViruses from extreme environments are still largely unexplored and may harbor unseen genetic potential. Here, we present a first glance at the morphological diversity of virus like particles (VLPs) from […]

The effect of geometry on ice shelf ocean cavity ventilation: a laboratory experiment
Read more of: The effect of geometry on ice shelf ocean cavity ventilation: a laboratory experimentA laboratory experiment is constructed to simulate the density-driven circulation under an idealized Antarctic ice shelf and to investigate the flux of dense and freshwater in and out of the […]
