PhD: Eddies and Sinking of Ocean Waters Engels -- Faculty/department Civil Engineering and Geosciences Level Master degree Maximum employment 38 hours per week (1 FTE) Duration of contract 4 years Salary scale 2083 to 2664 per month gross Civil Engineering and Geosciences The Faculty of Civil Engineering and Geosciences provides leading, international research and education. Innovation and sustainability are central themes. Research addresses societal issues. Research and education are closely interwoven. The faculty consists of the departments of Transport and Planning, Structural Engineering, Geoscience and Engineering, Water Management, Hydraulic Engineering, and Geoscience and Remote Sensing. The Department of Hydraulic Engineering is mainly concerned with major surface waters such as rivers, estuaries and seas. The focus is on understanding, designing and implementing human interventions in the natural environment for the discharge of water, for protection against water and for transport over water. Within the department, the Environmental Fluid Mechanics section focuses on the physical and mathematical aspects of free-surface water motion and directly contributes to the work of sections in the department. The Environmental Fluid Mechanics section is concerned with the fundamental fluid-mechanical aspects of processes in rivers, estuaries, coastal zones and oceans. The following research themes can be distinguished: wave dynamics, physical oceanography, shallow environmental flows and turbulence, and numerical fluid mechanics. Field observations, laboratory experiments and numerical modelling are considered key ingredients of successful research with relevance for practical applications. How the circulation near coasts and in the deep ocean interact is an important sub-theme within the section. Job description This PhD position is one of four positions available within this NWO-funded VIDI project. It involves fundamental research on deep ocean convection and sinking of dense waters in the North Atlantic Ocean, focusing on the role of ocean eddies for these processes. The research will be carried out in close collaboration with Utrecht University, Woods Hole Oceanographic Institution (USA) and University of Bergen (Norway). Exchange visits to these institutes are anticipated. At the margins of the North Atlantic (in the Labrador, Irminger, and Nordic Seas), surface waters cool, mix vertically with waters below, sink, and return southward at depth. This so-called Atlantic Meridional Overturning Circulation (AMOC) is of paramount importance for climate. Models predict that it slackens as climate warms, with considerable consequences. However, ocean eddies - recently found to be crucial for the sinking of dense waters - are still lacking in this picture. This project aims to quantify the role of

eddies for the response of the AMOC to high-latitude climate change, covering all relevant scales. The PhD candidate will focus on the Labrador and Irminger Seas. Using a highly idealised regional model, he/she will study the impacts of the local eddy activity on deep convection and sinking of dense waters and will determine the sensitivity of these processes to changes in local environmental conditions.
