Sea Ice Drift from GPS Tracker Deployed in the Arctic Ocean

Abstract

Sea ice is monitored on a regular basis by satellite observation; however, image-based drift tracking is imprecise as the time interval forming the image-pair is too large to capture the actual trajectory of ice drift. In this study, drift trajectory and speed of an Arctic sea ice floe measured by a GPS tracker for 3 months and the characteristics of the relating device and data, are introduced.
