The Department of Ocean System Research (OCS; Principal investigator dr. Femke de Jong) is looking for a highly motivated PhD student with a background in physical oceanography or meteorology with an interest in the exchange of freshwater between the Greenland boundary current and the open ocean.
Researchers in the Department Ocean System Research (OCS) study open-ocean processes from a variety of disciplines, ranging from physical and chemical oceanography, marine geology, paleoceanography to deep-sea ecology. We investigate the oceans in the past and present, to assess their future role. We make use of experiments and data collection during sea-going oceanographic research, as well as laboratory experiments and analyses in our home base on Texel. The department works around the globe, from the Antarctic to the Arctic, from the Caribbean to the North Sea. One of the areas we work in is the North Atlantic Ocean.
Researchers within OCS focus on the large-scale circulation of the subpolar North Atlantic and Nordic Seas. The northward transport of warm, buoyant water in the upper branch of the subpolar gyre, the transformation of buoyant waters to deep waters in convective regions and the southward flow of these deep waters along the western boundaries of the subpolar gyre are all key to the Atlantic Meridional Overturning Circulation (AMOC).
However, the formation of deep water is predicted to weaken due to climate change, both through increasing temperature stratification and the increased input of meltwater from Greenland and the Arctic, likely resulting in a basin-wide decrease of the AMOC. Still, the uncertainties on the exact impact on deep water formation and the consequences for the AMOC are still quite large.
This project is part of the NWO Vidi grant recently awarded to Femke de Jong, “From ice to deep ocean; where does the freshwater go?”. In this project, we will investigate the exchange of freshwater between the East Greenland shelf and the deep water formation regions and will determine the impact on local stratification and convective mixing.
We will carry out new field experiments with surface drifters deployed in the East Greenland Current to elucidate regions and mechanisms of liquid freshwater exchange. You will be part of the fieldwork and work on the drifter data set as well as on (reanalysis/satellite) products that give insight into the solid freshwater (ice)flux. You will collaborate with modelling groups in order to gain insight into statistics of the drifter data sets and variability beyond the duration of the field experiment.
We are looking for a highly motivated candidate with a university degree (MSc) in physical oceanography, meteorology, physics or a related area. You have a strong background in programming (Matlab, Python) and data analysis. Experience with Lagrangian data sets is of advantage.
Field expeditions to the East Greenland shelf are part of this research project. Therefore, it is essential you are willing to join cruises, for weeks at a time. Due to the international character of the research team, it is crucial you are proficient in spoken and written English.
Your position will be hosted by the Department of Ocean Systems (OCS) at the Royal NIOZ on the isle of Texel.
Employment of this position at Royal NIOZ is by NWO (The Netherlands Organization of Scientific Research). We offer a position for 4 (fulltime) years with an excellent salary, a pension scheme, a holiday allowance of 8% of the gross annual salary, a year-end bonus, and flexible work arrangements. You may expect attractive secondary employment conditions. We offer generous relocation expenses for employees coming from abroad and support with finding accommodation.
For additional information about the procedure, please contact Valentijn Tiemensma (senior HR advisor).
