About the Project

As rivers flow through the landscape, they can release greenhouse gases from their surfaces. Globally this is equivalent to ~20% of annual fossil fuel emissions. Despite knowing the importance of this flux, how it might change as landscapes and rivers warm is poorly constrained. This project will make novel measurements of carbon dioxide and methane release from rivers draining the Arctic and high latitudes. Using carbon isotopes to fingerprint the source of gases, the project will provide insight needed to make robust predictions about future change associated with Arctic warming. Find more information here.

Funding Notes

There is an ERC-Department studentship available for the project listed under Professor Bob Hilton. The studentship would be 3 years duration in the first instance, with the possibility of extension to 4 years. It includes fees at the home rate, stipend, travel and research funds, and is available to UK and overseas students; the studentship does not cover the difference between the home and overseas fee rates.
