内容記述 |
Nutrient concentrations in Koshikijima deep seawater pumped from a depth of 375m were examined from July 2003 to June 2004. Nutrients were variable and showed marked increases and decreases in a short period. However, average monthly concentrations of nitrate, phosphate, and silicate showed that there is some parallelism in the variation of nutrients. Mean N/P ratio (15) in the present study was close to the Redfield ratio of 16 observed in the open water. As sample water was taken significantly deeper than euphotic layer in the East China Sea, no chlorophyll was detected throughout the year. Dissolved organic nitrogen (DON) was at the level of oceanic surface water. It was concluded that Koshikijima deep seawater has the properties of open water in that it is less influenced by artificial factors. |
