Sea level fluctuations on the east coast of Taiwan that overlie continental shelf break

Abstract

Captured CO 2 could be deliberately injected into the ocean at great depth, where most of it would remain isolated from the atmosphere for centuries. CO 2 can be transported via pipeline or ship for release in the ocean or on the sea floor. No matter what for medium depth or deep sea, it appears that a potential area exists between 122-122.5°E and 21.8-22.3°N for CO 2 sequestration. The east coast of Taiwan can be a candidate for CO 2 temporary storage or transmitted plant. To have whole picture of assessment of sea level fluctuation, a completed statistical summary of seasonal sea level at six tidal gauge stations along the east coast of Taiwan is provided herein. Seasonal sea level time series is analyzed using spectral analysis in frequency domain to identify periodic component and phase propagation, especially for the astronomical-driven tidal effects. It identifies that the semi-diurnal and diurnal components in the resultant time series are related to astronomical tides M 2 , and K 1 and O 1 , respectively. It demonstrates a full analysis of sea level variations, and results can be useful when construction of testing or operating facilities on sea surface becomes desirable in the future.
