Abstract

Abstract

Radium isotopes in the water column along 64.3°N in the Bering Strait were determined to reveal the northward flow of the Pacific water. The specific activities of ²²⁶Ra and ²²⁸Ra, and the ²²⁸Ra/²²⁶Ra)_A.R. show a longitudinal variation in the Bering Strait, depicting the pathways of Pacific inflow. Based on the distributions of temperature, salinity and radium isotopes in the Bering Strait, three water masses were identified: the Anadyr Water in the western channel, the Alaskan Coastal Water in the eastern channel, and the Bering Shelf Water in the central strait. A subseasonal variation of radium isotopes in the Bering Strait was observed.The specific activities of ²²⁶Ra and ²²⁸Ra, and ²²⁸Ra/²²⁶Ra)_A.R. in September are higher than those observed in July, indicating water in the western Bering Strait is influenced by the southward flow of the Siberia Coastal Current in September.
