Quantifying the weathered fluxes to the ocean is far from over: the overlooked role of rock coast erosion
This study reveals that cliff derived sediment supply is only three times less than the solid discharge of rivers for Europe.

Oceanic Margins as sources of lithogenic particulate and dissolved iron in the North Pacific Ocean
Three GEOTRACES Japanese cruises on board the R/V Hakuho Maru allowed establishing basin-scale and full-depth sectional distributions of total dissolvable iron (tdFe), dissolved iron (dFe), and labile particulate iron (lpFe=tdFe […]

Unprecedented iron delivery from the Congo River margin to the South Atlantic Gyre
Radium isotopes are used to demonstrate that make the Congo the most significant riverine source of iron to the South Atlantic.

Tracing water mass mixing in the Cape Basin and the restricted Angola Basin with radiogenic neodymium isotopes
In the frame of GEOTRACES cruise GA08, Rahlf et al. (2020, see reference below) determined seawater profiles of dissolved radiogenic neodymium isotope signatures (εNd) and neodymium concentrations across the restricted western […]

Rare Earth distribution and pattern anomalies in the Solomon Sea
The Solomon Sea is surrounded by high and intensively weathered islands. Its complex topography and hydrography make this area a potential source of trace elements to the waters flowing through […]
The Scottish shelf break is not a significant source of iron to North Atlantic surface waters
A high resolution survey of the distribution of dissolved iron (dFe) over the Hebridean (Scottish) shelf break was conducted as part of the U.K. Shelf Sea Biogeochemistry programme, a GEOTRACES […]

Rare Earth Elements are less and less natural tracers in the ocean
This verdict is well illustrated by the recent study of Rodrigo Pedreira (2018, see reference below) off the North East Brazilian coast. His Rare Earth Elements (REE) data reveal marked […]

Revelations from the dissolved 226Ra-228Ra pair distribution in the South East Pacific Ocean
They show that radium-228 data coupled to the dissolved iron, cobalt and manganese provide evidence that lateral transport of sediments from continental margins.
