Great new paper by Dominic Hodgson and Tom Jordan from #BAS.

Using #Lidar, #Radar & #AirbornePhotography data, they identify the rapid drainage and slow refilling of a ~46m subglacial lake on the #AntarcticPeninsula.

Such findings have implications for the connectivity of the surface and #Subglacial hydrological networks, and, the authors hypothesise, the thermal regime of the #Ice.

#Antarctic #IceShelves are not just smooth, perfect slabs of floating #Ice, but rather contain areas of damaged ice that affect their strength and flow.

Building on previous work, Maaike Izeboud & Stef Lhermitte show how their "NeRD" method can detect different types and scales of damage (e.g. crevasse fields, large rifts, shear zones) in both SAR and optical #RemoteSensing datasets.

Direct measurements of physical properties in the #Cryosphere are often hard to come by, so I enjoyed reading this paper by Simon Oster and Mary Albert.

They measure the effective thermal conductivity (~ ability to transfer heat) of #Firn from #Antarctica, reporting values down to a depth of 48m, and showing conductivity can be well-explained as an exponential function of either density or depth.
