Due to thermocline and surface water from the western equatorial Pacific Ocean, which are transported to the Indian Ocean, Indonesian marine waters play an important role in the global ocean circulation. The objective of this study was to assess the spatial distribution of Cs in the Lombok Strait as part of a national monitoring program concerning the possible impacts of radionuclides released as a result of the Fukushima accident. Sampling was conducted in the Flores sea and Lombok Strait on 15 to 24 November 2013. Measurements for the Lombok strait showed that Cs concentrations at surface layer, thermocline layer and 1000m depth were 0.27Bqm; 0.42Bqm and <MDA (0.01Bqm), respectively. The water concentration of Cs at all monitoring stations were under MDA (0.01Bqm). The results the study indicate that the radiocesium input was from global fallout.
受西赤道太平洋的温跃层和表层水的影响，印度尼西亚海域在全球海洋循环中起着重要作用。本研究的目的是评估龙目海峡中 Cs 的空间分布，这是国家监测计划的一部分，旨在监测福岛事故释放的放射性核素可能造成的影响。采样于 2013 年 11 月 15 日至 24 日在弗洛雷斯海和龙目海峡进行。测量结果表明，龙目海峡表层、温跃层和 1000 米深处的 Cs 浓度分别为 0.27Bqm、0.42Bqm 和<MDA（0.01Bqm）。所有监测站的水 Cs 浓度均低于 MDA（0.01Bqm）。研究结果表明，放射性铯的输入来自全球沉降。
