Field instrumentation for real‐time monitoring of periglacial solifluction
Abstract Here we describe new field instrumentation recently installed on a non‐permafrost solifluction slope in Dovrefjell, Norway, and a continuous permafrost solifluction slope in Svalbard. The equipment is designed to provide continuous data on soil thermal status, hydraulic condition, phase cha...
