- During the winter, the dynamic response of the sea ice cover to wind forcing dominates the high frequency spatial and temporal variability of mass balance, by creating inhomogeneities that have a lasting effect on the energy balance.
- Improve our understanding of the relationship between sea ice thickness variability and sea ice motion variability by investigating stress and strain-rate relations with a comprehensive suite of spatiotemporal coincident observations.
- Determine if the viscous-plastic sea ice model, in a configuration used in current and next generation climate models, can realistically simulate the impact of ice dynamics on sea ice mass balance.
- Determine optimal sets of measurements to monitor pan-Arctic sea ice mass balance, utilizing model sensitivity studies to determine model uncertainties and identify key monitoring needs.
- Characterize the relationship between strain rate and changes in the regional thickness distribution.
- Characterize the relationship between, and coherence of, stress and strain rate at 10km and 100km.
- Test theoretical relationships between stress, strain rate, and regional thickness distribution.
- Validate models of ice dynamics: How well do they reproduce observed sea ice mass balance given known strain rates and/or realistic wind stress fields?
