GEOTRACES Science Highlights
North-South radium-228 section in the Pacific Ocean
Moore and colleagues present results from radium-228 along the U.S. GEOTRACES Pacific Meridional Transect (GP15).
Strong lithogenic imprints in the Indian Ocean waters
Ueki and co-authors reported the first sectional distributions of zirconium, hafnium and niobium along a north-south track in the Indian Ocean.
The development of the modern Antarctic Circumpolar Current occurred much later than previously thought!
This study is challenging the belief that the onset of the Antarctic Circumpolar Current was solely triggered by the opening and deepening of Southern Ocean Gateways.
A dynamic iron cycle in Peru
Gu and colleagues explore the temporal variation of iron over 11 cruises along the Peruvian shelf.
Trace metal fluxes of cadmium, copper, lead and zinc from the Congo River into the South Atlantic Ocean are supplemented by atmospheric inputs
Liu and colleagues show that rainfall augments some fluxes of trace metals from the Congo River.

GEOTRACES Publication Best Practices

 ✓ Please include “GEOTRACES” in either the title, abstract or keywords of your GEOTRACES publications. 
 Intermediate Data Product (IDP) data contributors: Please use the DOoR portal to add any new publication of your data included in the IDP. 
 ✓ Plea
se help us to acknowledge support from SCOR in your publications as follows
“The International GEOTRACES Programme is possible in part thanks to the support from the U.S. National Science Foundation (Grant OCE-2140395) to the Scientific Committee on Oceanic Research (SCOR).”
