Sarah Sapper is a PhD student at the University of Copenhagen studying methane and carbon dioxide emissions in meltwater from below the Greenland Ice Sheet. Department and group: Department of Geosciences and Natural Resource Management Supervisors: Jesper Riis Christiansen and Christian Juncher Jørgensen Dissertation title (as for now :D) Diurnal and seasonal dynamics of greenhouse gas emissions from subglacial meltwater of the Greenland Ice Sheet Some terms: Glacier: a body of ice moving down-slope due to gravity Warm glaciers: are very thick – the pressure of the overlying ice causes melting at the base of the glacier Cold glacier: thinner ice, the pressure of the ice doesn’t suffice to melt…
