Table 4 Correlation coefficients of monthly variations of tidal constituents calculated from a pair of neighboring stations. The correlation coefficient is calculated by weighting the amplitude of four major tidal constituents (M₂, S₂, K₁, and O₁). The correlation coefficients in excess of a 99.5% confidence level are marked. The correlation coefficient between KCTD and NMS09 is blank due to the short data length.
