Příbram – online data
Central Bohemia [49.6861°N, 13.9972°E]
The tidal group is working at this observatory located on top of an abandoned deep mine (depth 1300 m). At this site all istruments are maintained and undergo long-term tests in the mine gallery (tiltmeters, gravimeter, barographs, etc.). In the mine gallery there is also a seismological station.
The data from all other sites are transmitted to this tidal centre for control and processing. Besides a number of in-house software, the Preterna and Eterna packages (Germany) are used for data processing and analysis.
The photos show a typical digital/analog recording setup and a PC screen view of recorded tiltmeter signals with obvious Earth tide curves.
