项目摘要

This project has aimed to get wide and marvelous results in making new artificial upwelling structures and disclosing the current characteristics around the Okinawa shallow areas, having joint researches with a couple of the specific researches running in Okinawa.In this project, four other main projects have been joined, that are i) development of a ultra-power HF Ocean Raider, ii) developing a measuring and wide-broadcasting system of ocean current around the floating fishery boy, iii) developing a new structural analysis tools with free mesh finite element method, iv) developing a wide area wave observation system in the ocean around South islands of Japan. All of these projects have been succeeded in getting their final aims.In particular, this project has revealed the upwelling current around the self in Zanpa sea area of Okinawa. The main results obtained can be summarized as fellows :1) The tidal current around the Zanpa cape sea is in the clockwise direction.2) Clear thermoclines of the sea water temperature exist about 70m below from the sea surface.3) On the self, the thermoclines oscillate in harmonic with the tidal current.4) The upwelling flows around the Zanpa self can reach up to just below the sea surface.5) From the results obtained here, it can be said that the structures proposed as the artificial upwelling producers can make well-developed upwelling around them.

该项目旨在与冲绳正在进行的几项具体研究进行联合研究，在制造新的人工上升流结构和揭示冲绳浅海区域的当前特征方面取得广泛而令人惊奇的成果。在该项目中，还加入了其他四个主要项目，即i）开发超功率HF Ocean Raider，ii）开发漂浮渔童周围洋流的测量和广播系统，iii）开发采用自由网格有限元法的新型结构分析工具，iv) 在日本南岛周围的海洋中开发广域波浪观测系统。所有这些项目都成功地实现了他们的最终目标。特别是，这个项目揭示了冲绳残波海域自身周围的上升流。获得的主要结果可概括为：1) 赞帕岬周围的潮流为顺时针方向。2) 距海面以下约70m处存在明显的海水温度温跃层。3) 赞帕自身周围的温跃层与潮流和谐振荡。4) 赞帕自身周围的上升流可到达海面以下。5) 从所得结果来看在这里，可以说，作为人工上升流产生器提出的结构可以在其周围产生发育良好的上升流。
