An international team of researchers has established the first global estimate of hydrothermal mercury emissions from mid ocean ridge.
Breaking down disciplinary silos in marine sciences, a key to climate forecasting
Alessandro Tagliabue exposes how ocean modelling must evolve to take the biological complexity of the surface ocean into account.
