Antarctic glaciology. A glaciologist using a theodolite to measure deformation of the Ronne Ice Shelf, Antarctica. The ice here is about 1000 metres thick, and floats on the water of the Southern Ocean. The ice moves off-shore at a rate of about 500 metres per year, the leading edge fracturing to form icebergs.
