Abstract

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.
