GEOTRACES Science Highlights
High resolution of dissolved and particulate barium distributions in the Atlantic and Pacific Ocean reveal the importance of the margin sources on the oceanic Ba budget
Rahman and co-workers performed intensive samplings and analyses of barium along the GEOTRACES GA03 and GP16 transects.
Insight on the aluminium cycling during the inter-monsoon period in the Arabian Sea and Equatorial Indian Ocean
Full vertical water column profiles were established by Singh and Singh along the GI05 transect in the Indian Ocean during the fall inter-monsoon period in 2015.
The most important thorium-234 disequilibrium compilation you ever saw
Elena Ceballos-Romero and her colleagues propose a comprehensive global oceanic compilation of Thorium-234 measurements.
Machine learning approach led to the first iron climatology
Huang and co-workers propose the first data-driven surface-to-seafloor dissolved iron climatology.
Distributions, boundary inputs, and scavenging processes of trace metals in the East Sea (Japan Sea)
Seo and his colleagues show pronounced atmospheric and shelf inputs of trace elements in the Japan Sea.
New trace metal data in the Seas of Japan and Okhotsk
Nakaguchi and colleagues realized full-depth and section distributions of traces metals collected from the Seas of Japan and Okhotsk.
Special Focus

3rd GEOTRACES Summer School

The 3rd International GEOTRACES Summer School took place from the 10th to 15th July 2022 at the Alfred Wegener Institute Helmholtz-Centre for Polar and Marine Research (AWI) in Bremerhaven, Germany

During this Summer School, the idea was to provide the students with the toolset, the network, and the knowledge to oversee a project around marine trace elements and their isotopes.

Thanks to all GEOTRACES national representatives for all their work!
The Japanese GEOTRACES GP22 cruise is sailing in the western North Pacific Ocean
It will reveal the full-depth profiles of trace elements and their isotopes in the western North Pacific.
New Publication from GEOTRACES in a UN Ocean Decade Special Issue
GEOTRACES contributed to a special issue focused on the UN Decade of Ocean Science for Sustainable Development.
New Special Issue: Atmospheric deposition in the low-nutrient-low-chlorophyll ocean
The special issue presenting the results obtained during the PEACETIME process study cruise is now available!
