摘要: ABSTRACT Schmith, T.; Thejll, P., and Nielsen, J.W., 2016. Discussion of: Hansen, J. M., Aagaard, T. Kuijpers, A., 2015. Sea-level forcing by synchronization of 56- 74-year oscillations with the Moon's nodal tide on northwest European shelf (eastern North Sea to central Baltic Sea). Journal Coastal Research, 31(5), 1041–1056. We criticize important aspects analysis presented in Kuijpers (2015) (hereafter “HAK”) thereby cast doubt their conclusions. HAK claim that 18.6-year variations sea level are supported tidal theory, but this is not case; therefore, existence such must be explicitly shown. calculated amplitude spectrum annual harmonic found no significant peaks at periods claimed HAK. Next, we used results given reconstruct decomposition formed residuals subtracting from original data. variability near 18.6 years...
