Postdoctoral position in deep circulation and AMOC variability in the subpolar North Atlantic

We are seeking a highly motivated physical oceanographer for a postdoctoral position at Woods Hole Oceanographic Institution. The postdoc will work with a team of researchers on “Overturning in the Subpolar North Atlantic Program (OSNAP)”, the over-arching goal of which is to observe and understand the drivers of monthly-to-interannual variability in meridional fluxes of volume, heat and freshwater at subpolar latitudes in the North Atlantic.

The candidate should have experience in one or more of the following: analysis of moored current and temperature/salinity (T/S) observations, analysis of Lagrangian observations, and use of numerical model output with observations to build understanding of the relevant dynamics. Experience combining the above with other observational data sets (e.g., satellite altimetry and hydrography) to gain deeper understanding of the underlying physics is preferred. Expertise in meso-scale and large-scale ocean dynamics, and demonstration of completed research submitted or published in peer-reviewed journals is required.

The successful candidate will focus primarily on the analysis of a growing time series (2014-2024) from a transport-resolving current meter and T/S moored array in the Irminger Basin east of Greenland to develop a better understanding of the drivers of variability in transport and water properties of the Deep Western Boundary Current. A rich Lagrangian data set of deep acoustically tracked float trajectories, and observations from the Ocean Observatories Initiative’s Global Irminger Sea Array are also available to complement the moored observations. The postdoc is expected to include dynamical models as well as numerical model output where appropriate to extend the interpretation of the observations. There are many collaboration opportunities, with the OSNAP PIs at WHOI as well as with the U.S. and international OSNAP community virtually and at workshops. Further details of the research undertaken by the successful candidate will be determined by mutual agreement according to their experience and interests.

2 PhD positions in physical oceanography/climate dynamics at the University of Bergen, Norway

Two Ph.D. positions in physical oceanography/climate dynamics related to the overturning circulation in the Nordic Seas and Arctic Ocean are open at the University of Bergen, Norway. Both positions are for a fixed-term period of 3 years with the possibility of a 4th year with compulsory other work (e.g., teaching duties at the department). The positions are also associated with the Bjerknes Centre for Climate Research.



PhD1 will focus on the conditions conducive for water mass transformation in or near the East Greenland Current, identify when and where these are met, and place the present state of water mass transformation in the East Greenland Current into historical and future contexts. This will be achieved primarily through analysis of available and new observations, including moored and shipboard measurements of velocity and hydrography as well as hydrographic profiles from autonomous gliders and floats.

PhD2 will investigate the mechanisms of overturning variability in the Nordic Seas and Arctic Ocean, and especially the relationship between overturning circulation and surface forcing. The project will also assess how present and future overturning changes in the Nordic Seas are manifested in the subpolar North Atlantic (OSNAP). The PhD project will rely on the analysis of available observations and data from ocean models/reanalyses.

The deadline is 17 October.

PhD Position Unravelling the Physics Controlling the Atlantic Meridional Overturning Circulation

Dear colleagues

Within my research group I have an opening for a PhD student to work on the physics of the Atlantic Meridional Overturning Circulation, using realistic and idealized models [project abstract below for more details on the plan]

Applications are welcomed until mid-September.

In the Dutch system, PhDs become paid university employees for a 4-yr period but can also still enjoy the student facilities on campus. They spend their time almost entirely on their research project, except for tasks in assisting with education [max 10-15% of their time, typically grading exams, co-advising BSc and MSc students]. We expect they have a relevant education at MSc level when they start, although if needed they can take MSc courses / attend summer schools.

Feel free to forward the information to potential candidates.

The Atlantic Meridional Overturning Circulation (AMOC), characterized by northward surface currents and dense return currents, transports vast amounts of heat to high latitudes, and is largely responsible for Western Europe’s relatively mild climate. Climate models project the AMOC will weaken substantially over the 21st century, which impacts weather, climate, sea level and the oceanic carbon cycle. Ground-breaking new observations have led to a major change in our view on the AMOC, as they revealed that the circulation in the eastern subpolar North Atlantic dominates over that in the west. Notably, climate models tend to simulate the opposite. This illustrates their limited skills in representing key AMOC features and the underlying lack of in-depth understanding of its physical controls. This obviously casts doubt on the reliability of scenarios of future AMOC changes that rely on such models.

From theory and idealized modelling studies it is known that three processes in concert determine the AMOC in density space: (1) densewater formation in the interior of marginal seas and its subsequent export, (2) dense water formation within the boundary current system, and (3) the exchange of waters of differing density with the (sub-)Arctic via overflows. However, their relative importance for shaping the AMOC and feedbacks between them are still unknown. Moreover, both are expected to vary strongly across the subpolar North Atlantic since the key factors regulating their physics (eddy dynamics, surface forcing) vary as well. The observations only register the net effect of these processes, and hence careful analysis of ocean models is imperative to address this knowledge gap.

Here, analyses of realistic and idealized model simulations are combined to exploit the capabilities of both. First, the contributions of the three processes controlling the AMOC are quantified in sub-regions of the subpolar North Atlantic Ocean from a state-of-the-art model simulation, in depth and density space. Next, their sensitivity to oceanic and atmospheric conditions is systematically explored using an idealized model, which facilitates the qualitative identification of cause-and- effect relations and interdependencies. It provides crucial guidance for the final step: the quantitative analysis and interpretation of AMOC variations from the state-of-the-art model simulation. In all, the the project is expected to provide a robust framework to evaluate the skills of models in simulating the AMOC, help establish strategies for improving them, and aid the interpretation of observed AMOC variations.
