N2 - New index for showing the condition of lagoon is developed by testing the water quality in sea water and water in soil layer on site and after five days. The water quality is changing by the stored condition such as under the sun or no sunshine and aerated condition or sealed condition from the air. The change of water quality between on site and after five days under the four different conditions combined two conditions shown above can give some index of the situations in lagoon. The parameters measured for water quality are DO, COD, NH4, NO2, NO3, PO4, PH. And also temperature, salt density, turbidity, numbers of bacteria and numbers of microorganism are measured simultaneously. The index is made by these measured parameters with showing the vector diagram and correlation diagram between these parameters. The fields for observation are Sanbannse lagoon in Tokyo bay in Japan and Lamong bay in Surabaya, Indonesia, observation is continuing from 2005 to 2008. The former area is corresponding to the temperate zone and the last is corresponding to the tropical zone. So the authors can make the some index which shows the condition of lagoon by analyzing the relations between the change of these parameters and activity of creature.
