Abstract
Stable isotopes in snow on sea ice were observed in the Canadian Arctic Sea. Twenty-three snowpack and four new snow samples were collected along the length of expedition on foot from March to May in 2011. Stable isotopes in snow ranged from -25 to -35‰ in δ18O and from 3 to 13‰ in d-excess, and the local meteoric water line (LMWL) is δD=8.4*δ18O+18.7. There are no relationships between δ18O in snow and surface air temperature in this study. Temporal variation of δ18O in snow is influenced by the direction of moisture flux, low (high) δ18O in snow exists when southwesterly (northerly or easterly) moisture flux dominants.
