Sea Ice Modelling
We work on the physics of sea ice and its role in the polar climate system, combining numerical model developments and satellite remote sensing
We focus on the following research topics:
• To develop the new neXt generation Sea Ice Model called neXtSIM including:
an elasto brittle (EB) rheology to simulate sea ice dynamics and
an adapted code to simulate sea ice thermodynamics including the feedbacks between thermodynamical and dynamical processes
• To develop and implement a new module into neXtSIM that resolves waves-ice interactions in the Marginal Ice Zone.
• To provide daily sea-ice forecasts over the Barents and Kara Seas using the neXtSIM-F forecast platform based on the neXtSIM Lagrangian sea ice model (http://www.nersc.no/data/nextsim-f).
• To understand why sea ice behaves as it does and caracterize the scaling properties of the underlying physics responsible of its dynamical behavior using both model and observations.
• To (re)assess the role played by the sea ice cover motion and fracturing in affecting the upper ocean mixing, and regulating the primary production in the Arctic Ocean.
• To simulate and explain the reasons for the Arctic sea ice cover reduction observed over the last few decades, in a context of polar amplification and climate change.
