内容記述 | Dissolved organic matter (DOM) plays an important role in biogeochemical cycling within marine environments. Recent studies have shown that DOM consists of three fractions with different turnover rates : Labile-DOM and semi-labile DOM is degraded by bacteria within several hours and days, respectively, while refractory DOM is not degraded over thousands of years. The purpose of this study is to estimate the amount of semi-labile DOM and to detect a seasonal variability of that through degradation experiments of organic matter. The experiments were conducted using filtered and raw seawater samples collected from the depths of 20 m and 800 m of the Suruga Bay in April, July and October. After 21 days-long-degradation, decrease of organic carbon in the 20 m raw seawater reached to 26.2% as for the July sample, whereas it was 16.8% and 13.6% as for the April and the October samples, respectively. On the other hand, the corresponding value of filtered 20 m seawater was accounted for 24.7% as for the July sample, whereas it was 9.4% : as for the October sample. Primary production was highest in July and the surface water was well stratified in this period. These results suggest that semi-1abile DOM was accumulated in the surface water in July rather than in April and October. No significant changes were found in filtered or raw seawater collected at 800 m, suggesting the low contribution of semi-labile DOM in the mesopelagic zone of the Suruga Bay. | |||||||||
