- Postdoctoral Researcher
As part of the ERC-WAAXT project, LOPS-Ifremer (Brest, France) is offering two 1.5-year postdocs studying air-sea-ice interactions with an emphasis on the role of surface waves. Although the exact subjects will be tailored to the individual researcher’s specific interests and abilities, the work is divided into the broad lines of:
Postdoc in airborne remote sensing of waves and sea ice
This project will focus on addressing questions like: How does ice formation modify the wave fetch relation, and what are the implications for air-sea exchanges? How do ubiquitous sea ice streaks form? How can we link wave spectral attenuation in sea ice to ice characteristics? This project will use airborne video, lidar, and infrared imagery to study wave-ice dynamics, with a focus on ice formation processes. The postdoc would be expected to be involved in a planned field campaign in 2024.
Postdoc in wave-driven turbulence and mixing during ice formation
This project will be focused on upper-ocean turbulence, addressing questions like: How does the presence of frazil ice affect wave-driven turbulence? How does wave-driven turbulence interact with the unique salinity-driven density structure of the Arctic Ocean? How important are Langmuir circulations in this system? How does wave breaking affect ice formation? The work will use data taken as part of two campaigns, one in the Arctic Ocean (DarkEdge 2021), and one in the Lower St. Lawrence Estuary (WAAXT 2023), as well as exploiting modelling tools like Large Eddy Simulations. A third field campaign, planned for 2024 is also expected to be available.
Both postdocs will be based in Brest, France, and will offer the opportunity for local and international collaboration.
