中文摘要 | 自記式潮位站為快速蒐集潮位資訊之一種方法,其設置環境要求較連續式潮位站為低,因此設置成本亦較低。本文報告民國九十八年於東沙設置與操作壓力式自記式潮位站之一年來經驗,以為未來相關業務參考。本文分別就儀器與設置、維護與操作,陳述心得。就所犯錯誤、儀器特性與限制、以及所發現之各項疑點,條列說明。其中,並針對所用之潮位計,時間設定與其內部計時器誤差,以操作數據分析。本案所使用之兩具潮位計,均呈現約一天慢分一秒之現象,其鐘錶誤差遠大於該儀器所標稱之規格。 |
英文摘要 | Self-recording tidal gauge provides an efficient way of collecting tidal information. It is more adaptive to the environment and usually no construction is required. Therefore, the budget required for installation is relatively lower than the continuous tidal gauge station. This report summarizes what learned from the installation and operation of Dongsha self-recording pressure type tidal gauge in the past one year. Instrument characteristics and limitations are also documented. Among these, the time setting accuracy and the internal clock error are analyzed with the downloaded data during the operation. For two sets tidal gauge used in this study, both presented clock delay. The delay rate is about one second a day. This figure is somehow much larger than the nominal specification made by the manufacturer. |
