Emma Smith is geophysicist and glaciologist, investigating ice dynamics using active and passive seismic techniques. As part of the GHOST team she will focus on the collection of seismic reflection data using the Alfred Wegener Institute's (AWI) specially adapted vibroseismic source and snow streamer. These data are used to build up an image of the sub-surface structure beneath Thwaites Glacier and can be analysed to give properties, such as acoustic impedance of basal material, that are used to better inform predictive models of the evolution of Thwaites Glacier.
