Radium in Arctic surface water

The transpolar drift is strongly enriched in 228Ra accumulated on the wide Arctic shelves with subsequent rapid offshore transport. We present new data of Polarstern expeditions...穿极漂流（transpolar drift）显著富集了在宽阔北极陆架上积聚的镭-228（²²⁸Ra），且该漂流随后会发生快速离岸输运。我们展示了极星号（Polarstern）科考航次的全新观测数据……
