Description: Fluctuations in the length of day (Δlod) can be caused by temporal variations of the inertia tensor described by the excitation function and by disturbances of the torque balance between core and mantle. Recent models of the atmospheric excitation of the variations of the lod certainly failed with respect to longer periods (e.g., at about 70 years), but seem to be responsible for the annual period, the 22 years period and for a part of the nearly 30 years period. So, another geophysical phenomenon is needed which is responsible for the remaining part of unexplained lod variations. Previous studies of the geomagnetic core-mantle coupling were re-examined using lod values from which atmospherically excited parts were removed. The remaining part of the 30 years period could be explained by core-mantle coupling. Additionally, the torque blance was realized by assuming lower values of the electrical conductivity at the bottom of the mantle. It was concluded that the consideration of geophysical processes within atmosphere and hydrosphere will be important for future refinements of the core-mantle coupling models of the decade fluctuations in the lod.

Description: The amplitude spectra of global geophysical phenomena were investigated to motivate research of physical connections between them. The suggested causality was derived from comparison of the spectra, and from cross correlation functions. The following global parameters were discussed: for the earth rotation by the variations of the length of day, for the gemagnetic variation by the global field intensity, changes of the dipole axis and the westward drift, and for climate change by the atmospheric excitation function derived from air pressure variations, and temperature variations. The model of atmospheric excitation, which can be proved most exactly for the annual variation of length of day, is responsible for the 11 and 22 years periods, too. It failed for longer periods e. g., partially for the 30 years periods and completely for the 60 to 80 years periods, which were also discovered in the mean temperature and geomagnetic field variations. Therefore, it was suggested that longer periods in climate change and in the variations of the earth's rotation are caused independently by the same process in the earth core, provided that a physical influence of the geomagnetic field on climate will be accepted in future. The investigation was completed by comparison with the spectra of some local temperature variations in Europe.

Description: This technical report has been initiated, compiled and edited until March 1994. Its objective was to collect the existing geoscientific database and state of the art on the Uralides. It serves as a platform for financial and operational decisions by national and international funding agencies on the URSEIS95-project (Urals Reflection Seismic Experiment and Integrated Studies) under the EUROPROBE umbrella. The German DEKORP2000 (GFZ Potsdam), funded by BMBF, decided to operate this project in June 1994. Until November 1994, the COCORP project (Cornell University, U.S.A), funded by NSF, and CICYT (Barcelona, Spain) got funding to join a western consortium on the operation ofURSEIS in 1995. Until the end of 1994, a Russian consortium, funded by ROSGEOLCOM, was built under the leadership of SPETSGEOFISIKA (Moscow), integrating the BAZHENOV Geophysical Expedition (Sheelite, Ekaterinburg), BASHNEFTEGEOFISIKA (Ufa) and the GEON institute (Moscow). All partners in the project join forces in financing, acquisition, processing, interpretation and publishing the results of the seismic experiment. The field parameters of the experiment (chapter VI) have been slightly modified in the meantime and include the Vibroseis source technique. The field campaign is scheduled for May-September 1995. The interdisciplinary studies (chapter Vll) have been approved by the E.C. in the frame of the INTAS-programme (International Association for the Promotion of Cooperation with Scientists from the Independent States of the Former Soviet Union). in October 1994 and started their operational phase.
