Simulated heat storage in Canada's most northern lake: Towards a 3 dimensional model
This work focuses on heat fluxes and hydrodynamic of Ward Hunt Lake, Canada's most northern lake, as well as its response to climate variations. The project aims to implement a heat budget model, in order to improve our understanding of underlying mechanisms (water column stability, heat advect...
