The Earth's gravity fluctuates from place to place. Geodesists use this phenomenon to observe geodynamic and climatological processes. Using satellite-supported recordings, they document the strong fluctuations and the associated spatial and seasonal distributions of mass on and in the Earth. From this, gravity field models can be calculated by which researchers can track rising sea levels or melting glaciers, investigate regional groundwater reserves more closely or analyze oceanic currents.
