Monitoring and interpreting the Earth’s rotationvariations in general is an important task for Earth sciences, as they provide boundary which support othergeophysical investigations. This holds especially for sub-daily variations of the Earth’s rotation which areprimarily excited by variations of the oceans. Furthermore, atmospheric impacts as well as effects of theshape of the Earth are present. VLBI observations are in particular feasible. With VLBI all five parametersof the Earth’s orientation can be determined without hypothesis.
