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.

Hydrothermal activity detected above the ultra-slow South West Indian Ridge, using a multi-proxy approach

An original approach to assess the particulate trace metal concentrations in seawater

Sohrin and co-workers propose defining particulate trace metal as the difference between total dissolvable and dissolved metals after a long storage of filtered and unfiltered acidified seawater…

Constraining aerosol deposition over the global ocean by the cosmogenic beryllium-7

He and co-workers propose a global estimate of aerosol deposition onto the ocean using the cosmogenic radionuclide beryllium-7…
