An estimate of the mean field of Arctic sea ice motion

The observational basis for our understanding of sea ice motion comes from the trajectories of particular ice floes. These ice floes may have been marked by a manned research station or, more recently, by an automatic data buoy. Since 1893, almost 100 station-years of drift data have been recorded. Using the principles of optimal linear estimation, these data are used to obtain a quantitative estimate of the field of mean motion.
