本文以琉球與台灣之間海底電話電纜的電壓量測監測黑潮的流量,此海底電纜橫跨黑潮於其進入東海的入口處。我們自1993年3月起在琉球海纜站嘗試量測電纜電壓,當時該海底電纜(台琉海纜)仍在使用中,由海纜兩端的海纜站供應高電壓的定電流,自1995年的4月開始,在台灣端也開始量測海纜的電壓及電流以獲得完整的電纜電壓的資訊。觀測資料顯示,電壓的變化包括地球磁場的變動,潮流,黑潮及海流的長週期變化以及海纜供電系統的不穩定。本文報告海纜量測的初步成果並討論使用台琉海纜監測黑潮在東海入口處水流量的可行性。
The submarine telephone cable voltage has been observed between Okinawa and Taiwan for monitoring the Kuroshio volume transport. The submarine cable crosses the Kuroshio near the entrance into the East China Sea. We started the preliminary voltage measurement from the Okinawa cable landing site in March 1993. The submarine cable (Oki-Tai cable) is still in operation and is powered by a nearly constant electric current with high voltage power supplies at both of the cable landing sites. To get the full set of the cable voltage information we also started the voltage and current measurements from the Taiwan landing site in April 1995. Observations show the overlapped voltage variations are induced by geomagnetic field changes, tidal currents, longer-period ocean currents like the Kuroshio, unsteadiness of the cable power supply system, etc. This paper shows our preliminary results of the measurements and discusses the possibility of monitoring the Kuroshio volume transport using the Oki-Tai cable at the entrance into the East China Sea.
