Modelling the bio-cryosphere; how do glacier algal blooms contribute to the global carbon cycle?
About the project or challenge area
Blooms of extremophile ‘glacier algae’ lower the bare ice albedo of the Greenland Ice Sheet (GrIS), amplifying summer energy absorption at the ice surface and enhancing meltwater runoff from the largest cryospheric contributor to contemporary sea level rise. As blooms progress during summer melt seasons, the high net productivity of glacier algae forces the supraglacial system toward net autotrophy and drives substantial accumulation of autochthonous organic carbon within the weathered surface ice. Using the first numerical model of glacier algal blooms recently developed by Dr Williamson, this project will investigate the large-scale role of Greenland Ice Sheet glacier algal blooms in the global carbon cycle. Modelling experiments will be performe¬d to ascertain the potential contributions of ice sheet wide blooms to carbon sequestration and the fate of this carbon reservoir under various simulations.
Why choose this opportunity?
You will have the opportunity to work at the forefront of research into the importance of key cryospheric environments for global carbon cycles, learning key skills in numerical modeling and developing your knowledge on supraglacial ecology.
You will have an interest in polar microbiology and some numerical, GIS and modelling skills (preferably in R), though training will be provided where necessary.
