The Complete Annual Record of Sea Ice Volume Export Through Fram Strait as Observed by Satellite from 2010-2022.
Fram Strait is the primary pathway for sea ice export from the Arctic Ocean, yet estimates of volume export are constrained by observations of ice thickness and drift. Using a new year-round CryoSat-2 ice thickness product we determine an average annual export of 1,712 ± 452 km^3 from 2011-2022. 15%...
