As part of the ERC-WAAXT project, we are offering a Ph.D. project in ‘Investigating wave-ice feedbacks in the Arctic Ocean’.

Summer sea ice cover in the Arctic Ocean has been decreasing for decades, which is producing a corresponding increase in open water. This means that ice-free seasonal seas, with sufficient fetch for significant surface wave development, are now present. Since surface waves are a primary mechanism for the exchange of momentum, energy, and mass between the atmosphere and the ocean, the appearance of this wave climate is expected to be linked to a significant change in upper-ocean dynamics in the Arctic. The objective of this thesis is to investigate the feedback mechanisms, between the surface wave field, upper-ocean mixing, and sea ice cover, that are associated with the development of this seasonal wave field. These feedbacks are complicated, poorly understood, often contradictory, and their net effect on Arctic sea ice and climate remains unclear. The Ph.D. project will take a systematic approach to the problem, starting with basic theory and analysis of hindcast model output. In situ and remote sensing observations will then be used to improve model parametrizations, and new simulations explicitly including wave effects will be run and analysed. Findings will then be applied to future climate projections.

Applications are due on 2020-05-15

Candidates should have a strong background in math, physics, and numerical techniques. Experience in oceanography and fluid mechanics, particularly related to surface waves and turbulence would be very advantageous. A Master’s degree or equivalent is required.
