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 δ<SUP>18</SUP>O and from 3 to 13‰ in d-excess, and the local meteoric water line (LMWL) is δD=8.4*δ<SUP>18</SUP>O+18.7. There are no relationships between δ<SUP>18</SUP>O in snow and surface air temperature in this study. Temporal variation of δ<SUP>18</SUP>O in snow is influenced by the direction of moisture flux, low (high) δ<SUP>18</SUP>O in snow exists when southwesterly (northerly or easterly) moisture flux dominants.
