GEOTRACES Science Highlights

Different fates of four poorly soluble trace elements in the Pacific Ocean

Zheng and co-authors present the full-depth distributions of aluminum, lead, manganese and copper in the western South Pacific.

Internal tides, energetic dynamical processes that generate particle nepheloids at different depths

In this study, Barbot and co-authors identified the sites where internal tides are responsible for sediment resuspension...
