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: https://www.jobbnorge.no/en/available-jobs/job/249820/phd-research-fellow-in-physical-oceanography

PhD2: https://www.jobbnorge.no/en/available-jobs/job/249988/phd-position-in-climate-dynamics

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.

Regards,

Caroline Katsman

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.

Postdoctoral position – IFREMER

Applications for an 18-month postdoctoral position are invited from candidates with a recent PhD in physical oceanography or similar. The successful candidate will be based in IFREMER, Brest (France), and will join the“Ocean and Climate” team of the Laboratory of Physical and Spatial Oceanography (LOPS).

Project summaryThe sampling of the deep ocean (>2000 m) is primarily relying on intermittent shipborne surveys along sparse trans-basin hydrographic sections that cannot capture the full spectrum of oceanic variability. To overcome this issue and reduce the associated uncertainties on heat and freshwater ocean budgets, IFREMER and LOPS contribute to an international effort for the vertical extension of the Argo network towards the abyss – the Deep Argo network – by maintaining a regional pilot array in the subpolar North Atlantic. This region is key in the climate system since it is here that surface climate signals can enter the deep ocean interior, through the formation and vertical sinking of the North Atlantic Deep Water (NADW).

As part of the European project H2020 Euro-Argo RISE, the proposed work will combine newly available Deep-Argo profiles (Figure) and other observational datasets to obtain a better quantification and understanding of NADW intra-seasonal to decadal variability in the Irminger Sea. In parallel, the quality of Deep Argo data will be evaluated through an inter comparison of three different deep sensors mounted on a single three-headed float (Figure). On top of informing on the variability of the abyssal North Atlantic and its causes, these activities will provide a significant valorization of the Deep Argo dataset as well as crucial recommendation to the international community on technological choices for the global extension of the network.
