We thank all the crew and researchers on the cruise KH04-2 of the research vessel Hakuho-maru for their help with the expeirment. Especially Prof. K. Tsukamoto of the University of Tokyo, chief scientist of this cruise, gave a lot of assistance. Dr. X. R. Zhang of Doshisha University helped in the numerical simulation for the flow estimation. Dr. D. Yanagimoto of the University of Tokyo helped with the preparation of the experiment. This research was supported by Grant-in-Aid for JSPS Fellows.

N2 - A perpetual salt fountain can draw up deep sea water without any artificial energy source. This is one of the ideal ways to draw up deep sea water for nutrient enhancement application. A perpetual salt fountain experiment was carried out in May 2004. The estimated average velocity of the upwelling after 48 h from the start of the experiment was about 7 mm/s, and it continued for about 3 days. The flow rate with a single pipe was estimated as approximately 45 m3/day. The amount of upwelled deep sea water by this single pipe seems too small to be of benefit, but we can easily increase the amount by deploying a number of pipes.
