GEOTRACES Science Highlights

The Arctic Ocean is a net source of micronutrients toward the North Atlantic through the gateway of Fram Strait

Krisch and colleagues present a flux budget for micronutrient exchange between the Arctic and the North Atlantic Ocean.

Confrontation of two models to constrain the hydrothermal iron contribution to the Southern Ocean export production

Tagliabue and his co-workers compare the hydrothermal dissolved iron simulated by both models.

A better insight into parameters that control particle flux in the ocean

Xiang and coworkers compiled full ocean-depth size-fractionated particle data from 3 recent U.S. GEOTRACES cruises.

Assessment of deep-sea mining on Ocean health

Artigue and co-workers conducted a study to constrain how lithium and strontium from hydrothermal vents are dispersed in the ocean.

North African dust is an important (but not dominant) source of iron to the Gulf of Mexico

Hayes and colleagues have combined data to estimate how important North African dust could be as a source of iron to the Gulf of Mexico.

Nickel bioactive role in the oceans assessed by its isotopes

Lemaitre and her colleagues realized the simultaneous analysis of the dissolved nickel isotopes and concentrations in the North Atlantic.

Special Focus

New GEOTRACES interactive cruise map!

The interactive map allows you to view the completed and planned GEOTRACES cruise transects in all the different ocean basins in a glance. It also displays the basic cruise information when you hover the mouse over a transect or, by clicking on it, you can easily obtain the cruise report for completed cruises.

We invite you to navigate through this map, zoom to view each ocean basin in more detail or click on the buttons available on the map's legend to view the polar maps.
