Projections of likely sea level rise by 2100 range from 28 to 101 cm. This wide range depends a great deal on the amount of fossil fuel we burn over the next decades. However, due to poorly understood processes occurring in the ice sheets, and how they will respond to the warming climate and ocean, bigger numbers than this are not out of the question. One way to improve our understanding is with geophysical observations made on the ice sheet itself. In this talk I’ll explain how and why we do things like seismic experiments on ice shelves, record tiny icequakes from beneath ice streams and even measure the orientation of ice crystals using radar.
