PhD “The dynamics and controls of the carbonate system in Irish coastal and shelf waters” – National University of Ireland Galway/ Marine Institute

Closing date for applications: Thursday 30 June 2022 (but will remain open until filled).

Project description: Continental shelves are large and productive areas of the ocean and as such are a critical component of the carbon cycle. Knowledge of the carbonate system in shelf waters is key to understanding their variable status as source or sinks of CO2, which in turn is crucial to the accuracy of global and regional climate models. Coastal and nearshore waters, though much smaller in areal extent than continental shelves, are also important sources and sinks of carbon, and understanding the carbonate system here is of high importance. The goal of this Fellowship is to (a) test the hypothesis that the western Irish shelf is net sink of CO2 and (b) to test whether nearshore ecosystems such as seagrass and macro algal beds are a significant contribution to the CO2 sink capacity of the shelf. The student will divide their time between the Marine Institute and NUIG main campus interacting with the lively marine research community at both institutions.

In addition to working up existing data on inorganic carbonate parameters on the western Irish shelf and nearshore waters, the student will consider how to collect and integrate data relating to organic matter cycling in shelf and nearshore waters, to fill in this gap in our knowledge and to complement ongoing monitoring of the carbonate system. The project will forge links with the JPI Oceans/JPI Climate project CE2COAST ( and the Marine Institute funded BlueC and Quest projects which are just starting.

Stipend: €18,500 per annum & fees for 4 years.
Entry Requirements:
 A master’s degree or first class honours B.Sc. in a relevant discipline (e.g. oceanography, earth and
ocean sciences, marine chemistry, marine biology, or similar) with a good foundation in chemistry and
an interest in biogeochemical interactions
 Demonstrated seagoing experience on research vessels
 Experience with field monitoring and sample and data collection
 Adaptability, reliability and a positive attitude and the ability to work both independently and in a team
 A full Irish/UK/EU driver’s licence or licence from a recognized state will be an advantage
