The Sr activities of seawater were investigated in the high-latitude region of the Arctic Ocean from August-September 2017. The Sr activities in seawater in the Chukchi Sea, central Arctic Ocean and East Greenland Sea were 0.31-2.42, 0.12-1.86 and 0.13-1.20 Bq m, respectively. The average Sr activity (0.92 Bq m) below 500 m in the central Arctic Ocean was higher than those in previous reports. Our study provided high-resolution baseline Sr activity data for the whole water column in the high-latitude region of the Arctic Ocean (~85°N). The inventory of Sr in the central Arctic Ocean was higher than those in the Chukchi Sea and East Greenland Sea. The results of our study indicated that Sr could be transported to the deep seawater and remain in the Arctic Ocean for a long time.
本研究于 2017 年 8-9 月调查了北极高纬海域海水锶的活度。楚科奇海、中央北冰洋和东格陵兰海海水中锶的活度分别为 0.31-2.42、0.12-1.86 和 0.13-1.20 Bq m。中央北冰洋 500m 以深海水的平均锶活度（0.92 Bq m）高于以往的报道。本研究为高纬北极海域（~85°N）整个水柱提供了高分辨率的锶活度基准数据。中央北冰洋的锶储量高于楚科奇海和东格陵兰海。本研究结果表明，锶可能被输送到深海水中，并在北极海洋中长时间存在。
