Sea-ice ocean interactions occur at a diverse range of temporal and spatial scales; here I will focus on the mesoscale and sub-mesoscale ranges of motion. The first part of this seminar will explore the sea ice roughness dependence on the presence of eddies by using an idealised re-entering channel simulation (NEMO + SI3 ). An increase in the strength of the eddy intensity leads to a more spatially variable sea-ice cover during the freezing period, and it is capable of modifying the variability of the ice thickness over winter. Then, the second part will explore the seasonality of the kinetic energy on sea ice-cover oceans and the seasonal modulation of the oceanic scales of motion by sea ice.  Overall, the impact of eddies on the sea ice heterogeneity and their seasonality are processes that will become more important as the Arctic transitions towards a summer ice-free regime.
