The ocean plays a key role in controlling atmospheric greenhouse-gas levels. It removes a significant fraction of anthropogenic carbon-dioxide from the atmosphere, and also emits nitrous-oxide and methane, important greenhouse-gases formed by marine ecosystems. We urgently need to understand the processes regulating these air-sea fluxes, and how they will evolve under future global change. To accurately assess the combined impact of different greenhouse-gases on climate it is important to use models that integrate the underlying carbon and nitrogen cycles, and deliver a consistent greenhouse-gas flux response to global change.
In this project you will work with a team of scientists from UEA, the UK Met Office, and the British Antarctic Survey (BAS), to develop an integrated greenhouse-gas system in a global ocean biogeochemistry model. This work builds on recent research at UEA on the numerical modelling of the individual greenhouse-gases (carbon-dioxide, nitrous-oxide and methane). You will apply the integrated model to assess the combined oceanic greenhouse-gas response to a range of climate change scenarios, for example, accounting for the impacts of ocean warming and deoxygenation on marine biogeochemistry. The overarching aim will be to assess how the impacts of global change will affect the air-sea fluxes of the major greenhouse-gases within a consistent physical and biological model framework.
This is a collaborative project between UEA, the UK Met Office and the British Antarctic Survey. You will be guided by a supervisory team drawn from the different institutions, and receive training in ocean circulation and biogeochemistry, numerical methods, and associated climate data analyses. You will acquire skills in science communication, project management and collaborative research, and will be involved in a project of critical interest to oceanography and climate research communities.
This project is suited for a candidate with a background in natural sciences, engineering or mathematics, with strong numerical and programming skills, and interests in ocean biogeochemistry and global change.
