| 内容記述 | The effects of high and low concentrations of dissolved oxygen (DO) on nutrient fluxes from muddy and sandy sediments in Harima Nada were examined in terms of the change of nutrient concentrations in the supernatant seawater on the incubated sediments. The release of PO4-P and NH4-N under low DO conditions increased along the incubation periods while the increase of NO3-N was observed under high DO conditions. The fluxes of DIN (Dissolved inorganic nitrogen = NH4-N+NO3-N+NO2-N), PO4-P and SiO2-Si from muddy sediment were 1.8, -0.5, 130 mg · m-2d-1 under high DO conditions, respectively and 8.3, 3.5, 153 mg . m-2day-1 under low DO conditions, respectively. On the other hand, the fluxes of DIN, PO4-P and SiO2-Si from sandy sediments (11.6, 3.1 and 160 mg . m-2day-1 under high DO conditions, respectively and 36.0, 11.4 and 211 mg · m-2day-1 under low DO conditions, respectively) were higher than those from muddy sediments. This may be caused by higher activity of macrobenthos under aerobic conditions in sandy sediments where the benthic populations are more abundant than those in muddy sediments. Macrobenthos might play an important role on the nutrient regeneration from sandy sediment. | |||||
