Abstract

Abstract

The radionuclides ⁷Be, ²¹⁰Po and ²¹⁰Pb transported by the atmosphere can be used as important tracers for studying the material deposition flux of the Arctic Ocean’s atmosphere, modern ocean sedimentation and the transport of materials into the sea ice. They have been widely used in the study of air mass movement, soil erosion, and particle circulation processes in water systems. This paper reports the activities of ⁷Be, ²¹⁰Po and ²¹⁰Pb in the surface snow of the high-latitude ice floes of the Arctic Ocean in 2018. The activity concentrations of ⁷Be, ²¹⁰Po and ²¹⁰Pb are 33.6−632.68 mBq/L, 36.2−87.5 mBq/L, and 30.9−194.49 mBq/L, respectively. The activity concentrations of ⁷Be and ²¹⁰Pb in the surface snow of the Arctic Ocean are lower than those in the mid-latitude continental areas. The results show that the activity concentrations of ⁷Be in snow increased with the increase of latitude. The activity ratio of ²¹⁰Po/²¹⁰Pb ranged from 0.70 to 1.48 (with an average of 0.93), ²¹⁰Po is almost in equilibrium with ²¹⁰Pb. It indicates that the age of the surface snow is “older”.
