8. "What #mineral, produced by #subglacial #eruptions and spread via #aeolian distribution, is a problem for farmers in #Iceland, and why?"

#ChatGPT3 #GPT3 failed this (admittedly difficult) question (the answer is allophane, which binds phosphorus and other minerals, water, and reduces soil cohesion).

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.
