| 内容記述 | Nutrient fluxes from sediments in researched areas of Harima Nada, the Seto Inland Sea of Japan, were determined in terms of the change of nutrient concentrations in supernatant seawater on incubated sediments. Fluxes of DIN (dissolved inorganic nitrogen = NH4-N + NO3-N + NO2-N) and PO4-P were 3.0 ~ 64.8 mg · m-2 day-1 and-1.2 ~ 10.4 mg · m-2 day-1, respectively. High fluxes of the nutrients were recorded both in the northern part where it is shallow in depth and rich in organic matters in surface sediments and in the northeast part where it is poor in organic matters in surface sediments but abundant in macrobenthos. The flux of SiO2-Si ranged from 137 to 262 mg · m-2 . day-1, and was high in the northern and central parts where high concentrations of biogenic silica were recorded in sediments. Nutrient load due to regeneration from the sediment in whole Harima Nada based on the fluxes measured in this study was estimated to be 59 ton . day-1 for nitrogen, 5 ton . day-1 for phosphorus and 586 ton · day-1 for silica. In the summer studies the regeneration of nitrogen and phosphorus from sediments corresponded to 82% and 79% of the nutrient inflow from lands, respectively and silicate regeneration from sediments was equivalent to 2.5 times of the inflow from lands, indicating that nutrient regeneration from sediments contributes to large amount of nutrient inputs into seawater in Harima Nada . | |||||||||||
