Science Highlights

Overlooked riverine contributions of dissolved neodymium and hafnium to the Amazon estuary and oceans

Xu and colleagues investigated the isotopic composition of dissolved neodymium and hafnium along the entire salinity gradient of the Amazon estuary.

Pulling back the veil on reversible scavenging of lead

This work further contains the role that reversible scavenging may play in the cycling of lead in the ocean, an ever-evolving global experiment where lead contamination can be tracked in real-time.

Extremely high radioactive levels in the manganese nodules

Volz and co-authors demonstrate that radioisotopes in the manganese nodules mostly exceed exempt activity levels…
