“Quantifying and understanding the 3D dynamics and mixing of the subpolar North Atlantic Ocean (4 year fixed-term appointment)”

About the role:
An exciting opportunity is available within the UK contribution to a new international project, “Overturning in the Subpolar North Atlantic Program” (UK-OSNAP). We are looking for a highly-motivated postdoctoral researcher to apply novel inverse methods to estimate the ocean circulation from in-situ observations and satellite altimetry.

The subpolar North Atlantic is a key region for global climate dynamics. It links the global Meridional Overturning Circulation to high-latitude sites of deep convection and flow through gateways around the Arctic, yet its circulation remains poorly understood and its transport and mixing processes poorly captured by climate models. OSNAP is a collaborative project between the US, UK, Germany, Canada and the Netherlands that will sample the ocean at high frequency between Scotland, Greenland and Labrador. It will link to the RAPID array at 26°N and the EU FP7 ThOR project to systematically diagnose and monitor the circulation.

The researcher will primarily use Argo profiling float observations of temperature and salinity, together with the Tracer-Contour Inverse Method to estimate the 3D circulation and mixing in the North Atlantic on sub-monthly timescales. Other techniques will be applied to constrain the uncertainty due to physical assumptions and due to aliasing of the data by ocean eddies. The 3D, time-varying solution will then use information from the OSNAP and RAPID arrays to derive a best estimate of the North Atlantic circulation and mixing from the subtropics to the subpolar boundary.

This project will provide significant scope for major collaborative studies on physical processes and access to the latest observations and model output. By understanding flow variability and processes in this region, we aim to improve our understanding of global climate.

This post is offered on NERC terms and conditions

Salary: £26,450 to £29,710 per annum.

About you:
You must have a PhD in mathematics/physics/Earth sciences/engineering and have led or shown the potential to lead research projects. You should have a good knowledge of ocean dynamics and strong programming and communication skills, and the ability to conduct innovative research leading to high-impact publications.
