As a shelf-dominated basin, the Arctic Ocean and its biogeochemistry are heavily influenced by continental and riverine sources. Radium isotopes ( 226 Ra , 228 Ra , 224 Ra , and 223 Ra ), are transferred from the sediments to seawater, making them ideal tracers of sediment–water exchange processes a...
