Abstract

Subglacial processes are key to glacier dynamics, yet remain poorly constrained due to limited in-situ observations. We use continuous seismic and GNSS measurements to investigate summer subglacial processes in 2022 at Sermeq Kujalleq in Kangia (SKK; Jakobshavn Isbræ), Kalaallit Nunaat (Greenland). ...
