Leading Science Question:“What are the causes and consequences of an evolving and diminished Arctic sea ice cover?”
MOSAiC Science Drivers
Sea‐ice Lifecycle as a Theme. Use a sea‐ice “Lagrangian” perspective, where ice processes integrate forcings from atmos and ocean.

Large-Scale Implications
Jaiser et al.
• Large‐scale Transport• Synoptic variability• Linking local processes & hemispheric patterns
• Upscaling• Implications of regional change
