Radium isotopes (radium-228 and radium-226), water isotopes (oxygen-18 and deuterium), and salinity were measured on the slope of the East Siberian Sea in coordination with the 2018 Nansen and Amundsen Basins Observational System (NABOS) expedition. Radium is continuously produced at ocean boundaries and is soluble in seawater, thus it serves as an analogue for similarly sourced sediment-derived materials. Because the Eastern Arctic shelves are the origin of the Transpolar Drift, monitoring the radium levels in this region improves our understanding of potential climate-driven changes on the transport of shelf-derived materials offshore.
