Imagine the following: You are a grain of sand trapped under the ice. A lot of ice – in fact, let us say, 100 metres of glacier ice. How does it feel, how does it sound down there? You may hear the ice cracking, but sounds from the outside do not reach you, because the thick ice insulates so well. It is likely going to be cold, but also quite a stable temperature, because the ice buffers changes in outside air temperature. Laura Helene Rasmussen doing her fieldwork.
