GPR/GPS surveys and analysis of a firn core from the Gawn Ice Piedmont Glacier to examine Holocene climate history

To understand the drivers and consequences of climate change on timescales important to humans, the paleoclimate of ice cores, the glacial system and local climate patterns were analysed from the Gawn Ice Piedmont Glacier. A GPR/GPS (8, 35, 200 and 500MHz) survey was carried out to provide an image of the internal layering of the glacier and the topography of the ice-rock interface beneath. A 13m firn core was recovered and analysed for oxygen and hydrogen isotope ratios, major cations, anions and methylsulfonates, trace elements and cations, dust concentration and mineralogy.
