Abstract
We tested the marine environmental moniroring system off west coast of Hokkaido in Japan Sea from 1986 to 1988.
The system consists of marine observation buoy, land weather observatory, data receiving station, data management station and terminals.
Marine observation buoy forms 11 sensors for each layer in the different depth of the water. And, data management station has contoroller of data receiving and a function as the host station on personal computer communication.
This station transmits the observed data by access through the public telephone networks from each terminal.
We moored the observation buoy by using several rings for prevention of twistig.
Therefore, the buoy was able to endure waves of 5 meters high by using these rings.
