INterested in #Firn + #snow in #Antarctica? Just read this paper by Brooke Medley and it's a really nice piece of work..

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.

Here's an interesting recent modelling study led by Brice Noël about the ability of the #Greenland #Icesheet to retain #Meltwater in the #Firn layer under different #EmissionScenarios.

They show, under #SSP5-8.5, that the amount of meltwater that can refreeze will peak as early as 2100 in SW Greenland, subsequently leading to increased surface #Runoff and accelerated #SeaLevelRise.
