During this campaign our team plans to:

• Look at Hg transport across snow-sea ice-seawater interface in first-year and multi-year sea ice, with a particular emphasis on the potential production of methyl mercury in sea ice
• Study the vertical distribution if ikaite crystal within sea ice as well as the amount of phosphate co-precipitated with ikaite
• Examine Halogens distribution across snow-sea ice interface
• Test a new method for estimating CO2 flux through the sea ice during sea ice growth and decay
