Current Projects

I co-lead the IceVar project, a EU POLARIN funded project. IceVar uses repeated summer transects in 2026 between Svalbard and the North Pole aboard Le Commandant Charcot to investigate how spatial and temporal variability in Arctic sea-ice conditions shapes physical and biological processes and ecosystem productivity.I also lead the EU POLARIN IceVar-II project. IceVar-II extends the work of IceVar across years and platforms, combining further Le Commandant Charcot summer transects in 2027 with repeated observations (2026-2027) in the Arctic Ocean from Tara Polar Station during Tara Polaris I to better resolve seasonal-to-interannual changes in sea-ice habitats and their ecological consequences.
