oldest ice, with which we can reconstruct the climate of the past, more than one million years ago? For all of these questions observations on site are essential. This begins with the determination of the ice thickness, continues with the inference of the crystal orientation fabric in larger depth and ends with the composition of the subsurface below the ice, both of which govern flow behaviour of ice. In the end, we hope to make conclusions about how ice masses

all of us. Human activities are altering the composition of the atmosphere, and understanding how this connects to the changes we observe – and where it might lead – is one of the most pressing questions of our time. Earth's climate has shifted before, under conditions not unlike those emerging today. If we [...] temperature at a moment in the past.
