Response of the Atlantic Ocean circulation due to Greenland ice sheet melting and ecosystem impact
Dewi’s research is on the Atlantic Ocean circulation and in particular the sensitivity to Greenland meltwater runoff. To investigate the mechanisms at play in this problem we use the future generation of high-resolution climate models that resolves mesoscale eddies in most of the ocean (see figure). This is necessary since the dynamics of the response of the Atlantic Meridional Overturning Circulation to fresh water input around Greenland was shown to depend on model resolution (see Den Toom et al. 2014).
Dewi studied numerical modeling and mechanics at ENSEIRB-MATMECA a French engineering school situated in Bordeaux. With this background he came to the University of Utrecht for a PhD in physical oceanography at the IMAU under the supervision of Will de Ruijter and Henk Dijkstra. His focus was on understanding the Agulhas retroflection and measuring the Agulhas leakage, the flux of water from the Indian Ocean to the South Atlantic. Dewi graduated in March 2014 and since then started working on Water, Climate and Ecosystems. To learn more about his PhD research please visit his personal website.Contact Dewi
