为了评价人工上升流生产结构对低热带生产力的影响，进行了水动力学和低热带生态系统模拟。为了验证模拟的可重复性，使用了现场观察的结果。模拟结果再现了底层流动对结构的作用和内潮引起的温度脉动。但在温度混合层深度的评价上存在问题。在低营养生态系统模拟中，POC沉降通量被再现。模拟结果表明，受构造影响，初级生产力增加的区域南北向延伸30 km，东西向延伸10 km。增加值估计为1.3 mgC/m/d。
To evaluate the effect of artificial upwelling producing structure on lower tropic production, hydrodynamics and lower-tropic ecosystem simulations were executed. To verify the reproducibility of the simulation, results of the field observation were used. As a result, the bottom layer flow acting on the structure and fluctuation of temperature induced by internal tide were reproduced. However, the problem was left on the evaluation of mixed layer depth of the temperature. On lower-trophic ecosystem simulation, POC Sinking fluxes were reproduced. Suggested by the simulation, the area that primary production was increased by effect of the structure, extended 30 km north-south direction and 10 km west-east direction. And the value of increase was estimated at 1.3 mgC/m/day.
