Observation of Internal Wave Energy for Upwelling Deep Seawater

Abstract

Observation of an internal waves was carried out by a baymouth of the Ishikrin bay. In order to ask for the internal wave height of the Ishikari bay and the Shakotan peninsula circumference ocean space, the Coriolis tank was used and Hydraulic model test was carried out. Consequently, the internal waves of a reverse phase angle was observed the almost same period as tide waves in the 40m of the maximum wave height. Moreover, internal wave energy concentrates and the ocean space of 80m or more of wave height accepted to the Ishikari bay and the Iwanai bay. By this investigation, possibility of upwelling utilization using internal wave energy was verified.
