Drainage and refill of an antarctic peninsula subglacial lake reveal an active subglacial hydrological network

HIGHLIGHTS

SUMMARY

    Active subglacial hydrological networks have been revealed from changes in ice surface elevation detected by satellite altimetry and GPS (Willis et_al, 2015; Joughin et_al, 2016; Siegfried and Fricker, 2018; Neckel et_al, 2021; Livingstone et_al, 2022). Radio echo sounding has been used to identify subglacial lakes (Siegert et_al, 2005), and over-snow seismic surveys have been used to characterise their water column and sediment properties (Rivera et_al, 2015; Smith et_al, 2018). Much of this work has been carried out on large subglacial lakes under the East and West Antarctic ice sheets, while small lakes and . . .
