SEA ICE GEOCHEMISTRY: MERCURY, IKAITE AND PHOSPHATE

Location Station Nord, Greenland

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
