To ≈ 10 – 20 s V up to 295 times Half-day period (lunar term) at Potsdam From v. REBEUR-PASCHWITZ (1892) v. Rebeur-Paschwitz found in the records: • influence of air pressure and temperature changes on the records → discusses causes and need for shielding/avoidance. • increase of instrumental period with amplitude and sees the cause in elastic deformation of suspension and bearing components (theor. by Bessel). • the dominant influence of ocean tides and related crustal deformations in nearcoastal records (Wilhelmshafen, Teneriffa); • ← the half-day period (lunar term) of Earth tides; • the daily period of Earth tides; • diurnal and seasonal variations of → microseisms and their dependence on wind conditions; Peter Bormann XXIX ESC General Assembly, Sept. 12-17, 2004
In conclusion, he stresses the need for long-term permanent recordings in order to be able to investigate and separate these various complex influences: ↓ „ Given such a complex composition of a phenomena one can not expect to achieve remarkable results by means of only isolated sporadic observations. Rather, ... as in other related fields of natural sciences ... the real progress is only achieved by organizing well-planned and uninterrupted observations.“ 1892 Peter Bormann XXIX ESC General Assembly, Sept. 12-17, 2004
