Shelf‐basin interactions and water mass residence times in the western Arctic Ocean: Insights provided by radium isotopes
Radium isotopes are produced through the decay of thorium in sediments and are soluble in
seawater; thus, they are useful for tracing ocean boundary‐derived inputs to the ocean. Here …

Hydrothermal vents: A previously unrecognized source of actinium-227 to the deep ocean
Abstract Actinium-227 (t 1/2= 21.77 y) is produced by decay of protactinium-231 (t 1/2=
32,760 y). Abyssal sediments are enriched in 231 Pa and thus provide a source of the more …
