Fig. 3.1.2. Sea level records at Omaezaki (top), Maisaka (middle) and Toba (bottom) tide gauge stations after correction

for astronomical tide and the effects of the atmospheric pressure. The thick lines represent long-term changes in sea level at each station. The long-term changes are approximated by a line for Omaezaki and Maisaka, and by a cubic curve for Toba.

Fig. 3.1.3. Sea level changes after the average of the deviations from the long-term changes represented by the thick

lines in Fig. 3.1.2 is subtracted from each of the corrected records at Omaezaki (top), Maisaka (middle), and Toba (bottom) tide gauge stations.
