Breakout groups 1: Scientific Questions
1 : Sea ice•Inputs of TEI in sea ice•Transport of TEI by sea ice•Role of sea ice algae in TEI cycling•Role of sea ice in TEI cycling in central Arctic
2 : Rivers and shelves•Riverine inputs to the Arctic•Groundwater inputs to Arctic shelves•Shelf processes•Dense brine formation
3 : Aerosols and atmospheric deposition•Seasonality and trends of fluxes•What are the source regions•Effects of atmospheric deposition on water column
4 : Exchange with Atlantic and Pacific•Inputs and outputs at the choke points
Breakout groups 2: Sections and Process Studies
