Participation of the members of the Department of Planetary Geodesy in the international conference: 17th International Symposium on Earth Tides, Warsaw, Military University of Technology, 15-19 April 2013.

In the middle of April this year several members of the Department of Planetary Geodesy actively participated in the international conference Earth Tides Symposium (ETS), which is a cyclic conference organized every 4 years. The main organizer of the meeting is the Sub-Commission 3.1 of the International Association of Geodesy “Earth Tides and Geodynamics”. Over 70 scientists took part this year in the conference, representing among others France, Germany, Canada, China Nanking, Spain, Austria and USA. It was decided that about 25 papers presented at the meeting will be published in a special issue of the peer reviewed journal “Journal of Geodynamics”.


The conferences of the series ETS were concentrated in the past on the pure tidal research. Now the scope is much wider, covering a broad class of geodynamic phenomena which can be studied on the basis of the observed changes of the Earth’s gravity field. We could notice with pleasure that the research program of the geodynamic laboratory of the PAS in Książ follows strictly those worldwide trends. It seems that the most serious limitation of the geodynamic research in Poland, preventing our participation in such international programs like GGP (Global Geodynamic Project), is a lack of the superconducting gravimeter. An approximate cost of such instrument is 250-300 kEUR.


Participants from the SRC PAS:

- Aleksander Brzeziński – Member of the Scientific Organizing Committee; co-convener of Session 6 “Tides and Earth rheology”.
- Marek Kaczorowski – co-convener of Session 2 “Spring gravimeters, clinometers and extensiometers: instrumentation and results”.
- Wiesław Kosek
- Jolanta Nastula
