The aim of this project is to collect data to test a new theory of glacier surges - enthalpy cycling theory. The theory predicts that surges occur where frictional heating creates heat and meltwater (enthalpy) faster than it can be lost. This prediction will be tested for Kongsvegen, a glacier known to be in the earliest stages of a surge. In April and early May 2019, a pressure sensor, tilt meters, and temperature sensors will be placed in the glacier via a borehole, and used to measure changes in water storage, shear strain and heat loss. Additionally, ground penetrating radar will be used to collect data on glacier thickness, to supplement an existing DEM of the glacier bed. Data from the fieldwork will be used as input for simulations with the Elmer/Ice glacier model, to produce the first comprehensive enthalpy budget of a surging glacier.
