GEOTRACES Science Highlights
What controls the barium distribution in the Arctic Ocean?
Whitmore and co-workers synthesized what controls the barium distribution in the Arctic Ocean.
All what you wanted to know about mercury in the Mediterranean Sea…
Cossa and his co-workers summarized a critical review on the mercury budget, fate and health consequences in the Mediterranean Sea.
From Alaska to Tahiti, the distribution and bulk deposition fluxes of trace elements
Marsay and co-workers measured a suite of trace element was in aerosols collected in the North and equatorial Pacific.
Radium-224 and radium-223: powerful chronometers to estimate the residence time of Amazon waters on the Brazilian continental shelf
In this study, radium is used as a tracer for the waters of the Amazon that mix with those of the Atlantic Ocean.
In situ detection of Particulate Inorganic Carbon using optical sensors
Bishop and co-workers have developed optical sensors for particulate inorganic carbon concentration.This innovative system allows collecting real-time particle concentration.
When titanium is not always behaving as a lithogenic conservative tracer: an Amazon estuary story
They established the distribution of titanium in Amazon and Pará rivers and their related plume during the high discharge period.
