Science Highlights

Rare Earth and neodymium isotope cycles in the abyssal Pacific Ocean are shaking up the paradigm established for particle reactive tracers

Du and colleagues demonstrate the importance of the abyssal sediment source in the control of the trace element and isotopes marine distribution.

Anthropogenic iron impact on the surface productivity in the Pacific Transition Zone

Hawco and colleagues investigated the influence of industrial emissions on oceanic iron supply and its ecological consequences in the North Pacific.

Trace metal effluxes from Peruvian shelf sediments

Liu and co-authors compared four methods to estimate dissolved iron fluxes from Peruvian shelf sediments, revealing large variability.
