Vertical motions in Northern Victoria Land inferred from GPS: A comparison with a glacial isostatic adjustment model
Abstract Following the densification of GPS permanent and episodic trackers in Antarctica, geodetic observations are playing an increasing role in geodynamics research and the study of the glacial isostatic adjustment (GIA). The improvement in geodetic measurements accuracy suggests their use in con...
