Biography

Gerard is a oceanographer working in ICARUS (Irish Climate Research and Analysis Unit) and lecturer in the Department of Geography at Maynooth University. Gerard previously worked at the National Oceanography Centre in Southampton, UK, where he worked with the RAPID team measuring the Atlantic Meridional Overturning Circulation.

His research interests are in the role of the ocean in climate and how that might change with climate change. He publishes in a wide range of high impact journals including Nature. A full list of up to date publications is maintained here: bit.ly/13rwckn.

He leads the 2mE A4 project funded by the Marine Institute and the European Regional Development Fund and is co-Investigator on EirOOS—an Irish ocean observing system. He has been involved in a number of European Commission funded projects including the FP7 Thor and NACLIM, and is currently a workpackage co-leader of the Horizon 2020 project, Blue-Action.

He leads the GY369 module on Oceanography and they GY667 module on Oceans and Climate Change. He is a keen ocean-going scientist and has brought this to his teaching by taking the Maynooth University Climate Change MSc students of fieldwork on the Celtic Voyager (GY671).

Research Interests


I am interested in the role of the ocean in climate. In particular, the role of the Atlantic Meridional Overturning Circulation in the climate of northwest Europe. Sea level rise. Ocean salinity.
