On excitation of Earth's free wobble and reference frames [PDF]

The excitation of the Earth's polar motion in connection with problems that are associated with the diversity of reference frames involved in observations and theoretical computations is studied.

Studies of water storage and other contributions to changes in the rotation of the Earth [PDF]

The effects were determined of the global redistribution of water mass on various geodetic observables, especially polar motion, and complementary observables such as geodetic satellite positions.

Relaxation of Wobbling Asteroids and Comets. Theoretical Problems. Perspectives of Experimental Observation

, 2001
A body dissipates energy when it freely rotates about any axis different from principal. This entails relaxation, i.e., decrease of the rotational energy, with the angular momentum preserved.

High precision tide spectroscopy [PDF]

Diurnal and long period earth tides were measured to high accuracy and precision with the superconducting gravimeter. The results provide new evidence on the geophysical questions which have been attacked through earth tide measurements in the past.

The 14 month wind stressed residual circulation (pole tide) in the North Sea [PDF]

From published research it is known that a quasi-periodic 14 month atmospheric pressure oscillation of a few tenths of a millibar exists in the region of the North and Baltic Seas.
