利用有明海22个站位的完整柱状沉积物样品，研究了有明海表层沉积物特征和沉积物耗氧速率。沉积物特性的垂向分布表明，粉砂易富集大量有机质，使沉积环境恶化。沿着西海岸的AVS值大于沿着东海岸的AVS值，这是由于沿着东海岸沉积物粒度较粗造成的。SOC的实验结果和理论分析表明，溶解氧随时间呈指数下降，SOC速率与叶绿素a和脱镁叶绿素浓度之和呈线性关系。有明海有机碳流速随水温升高而增大，生物活动阈值在5 °C附近。
The sediment characteristics and the velocity of sediment oxygen consumption (SOC) were investigated using the intact cores sampled from the bed surface at 22 sites in the Ariake Sea. The vertical distributions of the sediment characteristics indicate that the silt tends to accumulate easily a large amount of organic matter and to make the sediment environments deteriorate. The values of AVS along the west coast tend to be lager than that along the east coast, because the grain of sediment along the east coast is coarse. The experimental results of SOC and the theoretical consideration showed that the values of dissolved oxygen decreased exponentially with time and the SOC velocity depends linearly on the sum of chlorophyll a and pheophytin concentrations. The SOC velocity increased with the water temperature and the threshold of biological activity was near 5 °C in the Ariake Sea.
