| [en] We compare vertical rates of deformation derived
from continuous Global Positioning System (GPS) observations and episodic measurements of absolute gravity. We concentrate on 4 sites in a region of North America experiencing postglacial rebound. The rates of uplift from gravity and GPS agree within one standard deviation for all sites. The GPS vertical deformation rates are signi cantly more precise than the gravity rates, primarily because of the denser temporal spacing provided by continuous GPS tracking. We conclude that continuous GPS observations are more cost e cient and provide more precise estimates of vertical deformation rates than campaign style gravity observations where systematic errors are di cult to quantify. | |
