Science Highlights
23 million years of productivity reconstructed in the Central Pacific Ocean using past and modern proxies
Using diverse geochemical proxies, Chu and colleagues analysed an iron–manganese crust to reconstruct central Pacific productivity over the past 23 million years.
Science Highlights
Major controls on the fate of dissolved manganese in the northeastern Indian Ocean
Malla and Singh investigated the key factors controlling dissolved manganese in the northeastern Indian Ocean…
Science Highlights
Long distance dissolved iron transport in the North-East Pacific revealed by multiple tracers and an ocean circulation model
Sieber and co-authors have made extensive use of the multi-tracer approach, coupled to an oceanic circulation model…
Science Highlights
What are the drivers of the distributions of cadmium, nickel, zinc, copper and cobalt, manganese and aluminium in the Atlantic Ocean? Two papers are tackling this issue
Chen and co-authors reveal that the distributions of dissolved tracers at depth in the South Atlantic are predominantly controlled by the mixing of North Atlantic Deep Water and waters of Antarctic origin…
Science Highlights
Aluminium, manganese, iron, cobalt, and lead display contrasting fate along north–south and east–west sections in the North Pacific Ocean
Chan et co-authors provide a comprehensive view of trace metal distribution in the subarctic Pacific Ocean.
Science Highlights
Extremely high radioactive levels in the manganese nodules
Volz and co-authors demonstrate that radioisotopes in the manganese nodules mostly exceed exempt activity levels…
