“Glaciers respond to a changing climate in a variety of ways. The aim of this study of the Kviarjökull glacier in southeastern Iceland was to map the 3D structural architecture of the glacier, including mapping fractures, faults and crevasses, to try and understand how the glacier moves and responds to changing inputs, such as temperature.”

Working with two colleagues from Durham University, the team found that only a portion of the glacier had moved since the last visit in 2013, but the move was significant, with the forward pulse creating a mound of sediment in front of it called a push moraine. How and why this pulse has happened will be one of the questions they hope to address in the coming months as they review the aerial imagery taken by the helicopter, and the 7km of GPR results that image inside the ice itself.
And the role of the Hobnobs? Food for thought..........
