Abstract
This paper presents the summary of research activities carried out in Poland in
2011–2014 in the field of Earth rotation and geodynamics by several Polish research
institutions. It contains a summary of works on Earth rotation, including evaluation and
prediction of its parameters and analysis of the related excitation data as well as research on
associated geodynamic phenomena such as geocentre motion, global sea level change and
hydrological processes. The second part of the paper deals with monitoring of geodynamic
phenomena. It contains analysis of geodynamic networks of local, and regional scale using
space (GNSS and SLR) techniques, Earth tides monitoring with gravimeters and water-tube
hydrostatic clinometer, and the determination of secular variation of the Earth’ magnetic field.
