为了发展冲之鸟志摩周边的鱼类产地，需要利用营养丰富的深层海水对海洋进行施肥。本方案对永续盐泉上涌法进行了研究。当上升流管停泊在海底时，存在管道上升流梯度的可能性。本研究针对冲之鸟岛的上升流管系泊，提出了利用集装箱展开流线型上升流管的方法。为建立该方法，设计了上升流管的铺管条件，并对使用容器的管管铺管方法的有效性进行了评价。利用阻力测量实验测得的阻力系数对管道坡度进行建模，并计算了用于系泊海底流线型上升流管道的浮标的浮力。并对25 m上升流管进行了展开实验，观察了管道的展开和容器下落的运动。利用该实验结果，对冲之鸟岛的集装箱下落运动进行了评价。
In order to develop the fish place around Okinotori-Shima, it has been required that the fertilization of ocean by the nutrient-rich deep seawater. In this proposal, the upwelling method by perpetual salt fountain has been investigated. When the upwelling pipe is moored at the bottom of the ocean, it has a possi-bility of gradient of the upwelling of pipe. In this study, to moor the upwelling pipe at Okinotori-Shima, the method which spread the streamline upwelling pipe by using container is proposed. To establish this method, the spreading condition of upwelling upwelling pipe was designed and the availability of spreading method of pipe using container was evaluated. The gradient of pipe was modeled with drag coeffi-cient measured by drag force measurement experiment and the buoyancy of the buoy to moor the streamline upwelling pipe at the bottom of the ocean was calculated. And also, the experiment of spreading of the 25 m upwelling pipe was conducted and the spreading of the pipe and the movement of dropping of container were observed. Using this experimental result, dropping movement of container at Okinotori-shima was evaluated.
