PhD (m/f/d) in Physical Oceanography

The sea ice in the Arctic Ocean has been retreating dramatically under global warming. In the Eurasian part of the Arctic Ocean, there is evidence that vertical stratification in the upper ocean has weakened substantially in recent years, such that the upward heat flux from the subsurface Atlantic Water layer may have contributed strongly to the decline in sea ice. This scenario has been referred to as “new Arctic” regime. In the perennially ice-covered central Arctic Ocean, instead, the halocline is thought to still prevent strong upward heat fluxes year-round. However, wintertime measurements hardly exist in leads within the central Arctic Ocean, where sea-to-air heat fluxes may be strongly enhanced. Therefore, the feedbacks between upward heat fluxes from the halocline across the mixed layer toward the sea ice and small-scale horizontal processes are not well understood.

Tasks

• establish how horizontal ocean processes in both regions modify the heat exchange between the stratified upper ocean, the mixed layer and the atmosphere / sea ice during events like opening of leads, passing storms, sea ice melt, passing oceanic eddies or the decay of fronts in the upper ocean
• receive an intense training in advanced techniques of data analysis,
• be able to join a research expedition to Fram Strait in summer 2020 to obtain a hands-on experience

Requirements

• M.Sc. degree in physical oceanography, environmental physics, climate physics, or related fields.
• An excellent background in fluid dynamics
• good programming skills (preferably in Matlab)
• very good command of English in writing and speaking (corresponding to level B2/C1)
• be willing to interact with an interdisciplinary science community.
• expectation to participate in scientific, polar expeditions.
