Multi-year ice thickness: knowns and unknowns
Nearly 5000 direct measurements of multi-year ice thickness, compiled from studies spanning a period of 51 years, are used to identify some of the “knowns and unknowns” surrounding multiyear ice. Many of these studies reside in the grey literature, which makes this paper one the few in the open lite...
