Minimum 60 years of recording are needed to compute the sea level rate of rise in the Western South Pacific

Abstract

AbstractSea levels generally oscillate with multi-decadalperiodicities worldwide with up to the quasi-60 years detectedin many tide gauges. Nevertheless, the most part ofthe literature on sea levels computes apparent rates of riseof sea levels much larger than the legitimate by using shorttime windows in selected locations only covering part of avalley-to-peak of this multi-decadal oscillation. It is shownin this paper that along the Pacific coast of Australia thesea levels oscillate with a frequency close to the SouthernOcean Index (SOI) oscillation of 19 years and a lower frequencyof about 60 years. The rates of rise of sea levelscomputed by linear fitting of the data recorded since theearly 1990s in selected locations of the Australian Pacificcoastline and in the tropical Pacific islands are from a valleyof the peak and valley oscillations and are much higherthan the legitimate long term values.
