Overview

• Researchers analyzed roughly 20 years of measurements from 58 GNSS stations to resolve Greenland’s horizontal land motion.
• The island has moved about 2 centimeters per year toward the northwest over the past two decades.
• Data show regional expansion in some areas and contraction in others, producing a small net shrinkage at present.
• The analysis merges contemporary observations with a model spanning about 26,000 years to attribute drivers of the motion.
• The peer‑reviewed results in JGR: Solid Earth (DOI: 10.1029/2024JB030847) have geodetic consequences as shifting reference points affect surveying and navigation.
