Kagoshima bay has a highly active volcano in its center. In the filtered seawater and suspended matter collected from 200-m deep fumaroles at the bottom of the inner bay, the geometric mean concentrations of total mercury were 7.6 and 65.0 ng/L, respectively. The surface seawater collected at the inner bay had a higher concentration of mercury when compared to that in the bay entrance (average: 1.0 vs. 0.5 ng/L). In July, however, no such difference was observed. The fumaroles seem to contribute to relatively high concentrations of mercury in the inner bay except in summer, when thermal cline is formed.
鹿儿岛湾的中心有一座非常活跃的火山。在从内湾底部 200 米深的喷气孔采集的过滤海水和悬浮物质中，总汞的几何平均值浓度分别为 7.6 和 65.0ng/L。与湾口（平均值：1.0 对 0.5ng/L）相比，在内湾采集的表层海水汞浓度更高。然而，在 7 月，并未观察到这种差异。除了在夏季形成热梯度之外，喷气孔似乎对内湾内相对较高的汞浓度有一定贡献。
