台湾东北海域龟山岛海底热液原位观测数据周期性的小波分析
Wavelet analysis of in-situ observation data on its periodicity of hydrothermal vents on the seafloor of Kueishan Island
摘要
Abstract
From May 25 to 30, 2011, a joint research was taken on the hydrothermai vents on the seafloor of Kueishan Island, and a series of sensors were located at a White Spring vent (24. 83419N; 121. 96198E) , which lies close to Kueishan Island, to the northeast of Taiwan Island. In situ observation data were processed with Morlet Wavelet. Wavelet coefficients of temperature and pressure were calculated and variation periodicities of the two factors with time were extracted. The results showed that the characteristic of local tidal were both semi-diurnal periodicity and diurnal periodicity. The periodicity of temperature was inconsistent with the periodicity of pressure, which was explained as there had the same internal cause between strength of hydrothermai eruption and the fluctuation of sea water, but different response to the external gravitation of the hydrothermai and the sea water.关键词
