Topics

The Topics that are relevant to the Earth Tides and Geodynamics Commission take into account geodynamic phenomena on different temporal and spatial scales. These geodynamic phenomena can be observed by modern instrumentation and monitoring systems, both terrestrial and space-borne. The seminars will be open for a wide range of scientific problems in geodynamics research. Interactions of geophysical fluids with Earth tides phenomena and observations are a specific focus and includes:

Tidal and non-tidal loading in space geodetic and subsurface observations
Permanent and dynamic effects of Earth tides on the geodetic reference system
Using tides and ocean tidal loading with modern geodesy to probe Earth structure
Variations in Earth rotation, gravity field and geocenter due to mass redistributions
Tidal forcing of plate movement
Subsurface fluid movement through geodetic and gravity observation
Fluid pressure changes due to Earth tides
Stress and deformation changes due to injected fluids
Earth tides, mass movements and deformation at volcanoes
Tidal effects on geodetic satellites as GOCE, GRACE, …
Innovations in instrumentation for gravity and deformation observation
Innovations in software, data analyses and prediction methods of loading and tides
Induced seismicity
Tides and geodynamics in planets
