Abstract
δ18O profiles in drifting Arctic sea ice are coupled with back trajectories of ice drift and an ice growth model to reconstruct
the surface hydrography of the Arctic Ocean interior. The results compare well with δ18O values obtained by traditional oceanographic methods and known water mass distributions. Analysis of the stable isotopic
composition of sea ice floes sampled at strategic and relatively accessible locations, e.g., Fram Strait, could aid in mapping
spatial and temporal variations in Arctic Ocean surface waters.
