2009年夏季，对伊沙哈亚湾海底沉积物环境特征进行了全面调查。沉积物粒度由中粉砂到细粉砂组成。IL值均大于10%，其中有机污染在围垦堤防两个排水口附近加重。AVS值大于渔业用水标准，湾头沉积物处于厌氧状态。沉积物耗氧速度在靠近南排水口处最大。AVS、NH4-N、NO2-N+NO3-N和PO4-P与ORP的关系表明，海底沉积物处于硫酸盐还原状态，PO4-P已在沉积物中释放。
The environmental characteristics of seabed sediment in Isahaya Bay were investigated comprehensively in summer of 2009. The sediment was composed of the grain size from medium silt to fine silt. The value of IL was totally higher than 10 % and especially the organic pollution advanced near the both drain gates of the reclamation dike. The value of AVS was larger than the standard of water for fisheries and the sediment at the head of the bay was in the anaerobic condition. The velocity of the sediment oxygen consumption took the largest value near the south drain gate. The relationships of AVS, NH4-N, NO2-N+NO3-N and PO4-P versus ORP revealed that the seabed sediment had been in sulfate reduction and PO4-P had been released in the sediment.
