| Research Abstract |
The object of this research is to develop in situ automatical continuous ammonium measuring system for investigating nutrient dynamics related biological production and food chain in marine ecosystems. This system is employed with drifting buoy in the ocean. There is few difference of sensitivity between this system and previous manual methods in the loboratory. We could get high stability and high detection sensitivity by improvement of flow-cell, amount of chemical regents and tubules. Test operation of this system was carried out in the large outdoor tank with 3 m on February 2000 and we coud collect data every one hour is sute.
