Journal ArticleDOI
The thermal regime of sub-polar glaciers mapped by multi-frequency radio-echo sounding
Helgi Björnsson,Yngvar Gjessing,Svein-Erik Hamran,Jon Ove Hagen,Olav Liestøl,Finnur Pálsson,Björn Erlingsson +6 more
TL;DR: In this paper, the thermal regimes of polythermal glaciers in Svalbard have been investigated using radio-echo soundings at a regional scale, where the free water content in the ice at the freezing interface is about 1 % of the volume.

Chapter 11 - The NASA Mars 2020 Rover Mission and the Search for Extraterrestrial Life
Kenneth H. Williford,Kenneth A. Farley,Kathryn M. Stack,Abigail C. Allwood,David Beaty,Luther W. Beegle,Rohit Bhartia,Adrian J. Brown,Manuel de la Torre Juárez,Svein-Erik Hamran,Michael H. Hecht,Joel A. Hurowitz,Jose Antonio Rodriguez-Manfredi,Sylvestre Maurice,S. M. Milkovich,R. C. Wiens +15 more
TL;DR: The NASA Mars 2020 rover mission will explore an astrobiologically relevant martian site to investigate regional geology, evaluate past habitability, seek signs of ancient life, and assemble a returnable cache of samples as mentioned in this paper.
Journal ArticleDOI
Spatial distribution of snow in western Dronning Maud Land, East Antarctica, mapped by a ground‐based snow radar
TL;DR: In this article, the spatial distribution of snow in western Dronning Maud Land, East Antarctica, mapped by a ground-based snow radar was mapped by the ground-truth radar.
Journal ArticleDOI
