Post-Doctoral Researcher – Bangor University

Applications are invited for the above full-time research position to investigate the importance of Arctic ice and freshwater in altering upper ocean properties and sea surface temperature (and therefore air-sea heat fluxes and atmospheric circulation) in the subpolar basin, Nordic Seas and Barents Sea.

This position has been funded by the Natural Environment Research Council as part of the ArctiCONNECT project that seeks to resolve the connections between rapid Arctic warming and European climate and weather. The researcher will join the School of Ocean Sciences physical oceanography group, and a much wider consortium of investigators around the UK from the fields of meteorology, climate dynamics, polar and subpolar oceanography. The research to be carried out by the successful applicant will contribute to Objectives 2 and 3 of ArctiCONNECT that seek to identify the ocean pathways by which climate-impacting signals are communicated from the Arctic to the subpolar basins and vice versa, and establish the coupled-interactions of these regions. Specifically, the Bangor researcher will be responsible for retrieval and analysis of Arctic oceanography datasets including reanalysis products, gridded hydrography, ice-tethered profiler data and numerical model output.

Candidates should possess or be close to the completion of a PhD in Physical Oceanography or a related discipline such as meteorology, or possess equivalent experience. Previous experience in the analysis of large oceanographic or atmospheric data sets, including reanalysis and/or general circulation model output is essential.

The successful candidate will be expected to commence their position on 1 June 2021, or as soon as possible thereafter and the post is available until 31/05/2023.

Please submit a 2-page CV in addition to the completed application form.

Committed To Equal Opportunities.


The School of Ocean Sciences (SOS), located on the beautiful shores of the Isle of Anglesey, is a multidisciplinary department with a focus on continental shelf sciences and a strong history of international research excellence and collaboration. Core research interests include oceanography, marine biology and ecology, aquaculture & fisheries, biogeochemistry and climate change science. This position will be based in the SOS – a state-of-the-art facility that acts as a hub for cross-disciplinary research, reflecting the interdisciplinary nature of marine science in the College of Environmental Sciences and Engineering.

The Project

In the warming climate, the Arctic region is undergoing dramatic changes in all components of the coupled atmosphere-ocean-ice-land system. Half of the Arctic summer sea-ice cover has disappeared in only 40 years [Notz &Stroeve, 2017]. Greenland Ice Sheet melt has accelerated in the past 30 years, with ~3,800 billion tonnes of ice lost between 1992 and 2018 [Shepherd et al., 2019]. The Arctic lower atmosphere is warming at more than twice the rate of the global average, a phenomenon known as Arctic amplification [Screen& Simmonds, 2010]. Observed changes in the ocean include the recent freshening of the Beaufort Gyre, by 40% from 2003 to 2018 [Proshutinsky et al., 2019], and the ‘Atlantification’ of the Barents Sea [Barton, Lenn, Lique, 2018] and of the Eastern Arctic Ocean [Polyakov et al., 2017].

Past work has indicated that Arctic amplification might affect Europe, but a clear picture of how is still lacking. Consequently, the 2019 Intergovernmental Panel on Climate Change (IPCC) Special Report on Oceans and Cryosphere concluded “changes in Arctic sea ice have the potential to influence midlatitude weather, but there is low confidence in the detection of this influence for specific weather types”. A major impediment to confidence in the far-flung effects of Arctic amplification is that the physical mechanisms are poorly understood. The rapidity of the changes in the Arctic in recent decades poses a particular challenge for separating any potentially forced signal from the large natural variability of the climate system. Hence, there is an urgent need for dynamical considerations, rooted in physical theory, to overcome these knowledge gaps.

To address these challenges this interdisciplinary project draws together experts in meteorology, climate dynamics, polar and subpolar oceanography from eight institutions across the UK, including the UK Met Office. We propose to untangle the impacts of various atmospheric and oceanic drivers and coupled interactions through six project objectives that will investigate atmospheric pathways (O1) and oceanic pathways (O2) by which rapid change is communicated from the Arctic to the North Atlantic and back, coupled interactions (O3), state dependence (O4), extreme weather (O5) and European Hazards (O6). The Bangor position will focus on deliverables in O2 and O3, and will be jointly supervised by Dr Yueng-Djern Lenn at Bangor and Dr Helen Johnson, Oxford University, in collaboration with Dr Camille Lique at IFREMER, France.

Purpose of the Job

The post is part of an established team at SOS working in the area of Arctic oceanography. The postholder will determine the importance of Arctic ice and freshwater in altering upper ocean properties and SST (and therefore air-sea heat fluxes and atmospheric circulation) in the subpolar basin, Nordic Seas and Barents Sea. This will be achieved by applying a potential energy anomaly (phi) analysis to establish the local impact of different processes (ice melt, river input, wind, radiative fluxes, tidal mixing, lateral advection…) on the buoyancy content of the water-column and its changes. The phi-analysis will enable the mapping out of where and how ice and Arctic freshwater export are important in determining upper ocean properties and sea surface temperature (SST), with the potential to influence (i) the atmosphere, and (ii) the watermass transformations important for the overturning circulation further south. The datasets to be used include a high-resolution regional ocean-ice simulation or state estimate, in combination with observed SSTs, ITP profiles and reanalysis data. This analysis will enable the post-holder to quantify the contribution of the various processes to recent changes, and assess their representation in the current generation of coupled climate models.
