Deception Island is an active volcano located in the south Shetland Islands, Antarctica. It constitutes a natural laboratory to test geophysical instruments in extreme conditions, since they have to e...
Basal roughness of the Institute and Möller Ice Streams, West Antarctica: Process determination and landscape interpretation
Antarctica Roughness Radio-echo sounding Ice dynamics Mö ller Ice Stream Institute Ice Stream
2014/5/20
We 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 asses...

Getting around Antarctica: new high-resolution mappings of the grounded and freely-floating boundaries of the Antarctic ice sheet created for the International Polar Year
Antarctica the grounded freely-floating boundaries
2014/5/20
Two ice-dynamic transitions of the Antarctic ice
sheet – the boundary of grounded ice features and the freely-floating boundary – are mapped at 15-m resolution by par-ticipants of the International P...
Postspreading rifting in the Adare Basin, Antarctica: Regional tectonic consequences
West Antarctic rift system rift Adare Basin multichannel seismic reflection magnetic anomalies tectonics
2014/4/10
Extension during the middle Cenozoic (43–26 Ma) in the north end of the West Antarctic rift system(WARS) is well constrained by seafloor magnetic anomalies formed at the extinct Adare spreading axis.K...

Field Measurements of the Total and Spectral Albedo of Snow and Ice in Dronning Maud Land, Antarctica
albedo spectral albedo snow blue-ice Antarctica
2009/6/9
Variabilities in the spectral and total (between 300-3000 nm) albedo of snow were studied in the Dronning Maud Land region of Antarctica during the austral summers of 1999/2000 and 2000/2001. The meas...
