Seiches and Harbour Oscillations

The fundamental period of the bay (Helmholtz mode) is 35 min, and this period prevails in seiche oscillations inside the bay (95% of all observed events) and it was specifically this period that was observed on 31 March 1979 [Akamatsu, 1982]. HK noticed that almost all known cases of significant abiki waves are associated with pressure jumps. ................
