This section presents the GEOTRACES scientific activities.
A detailed study of the land-ocean input of dissolved iron, manganese and cobalt in the Northeast Atlantic Ocean
Chen and co-authors propose a detailed study of the spatial and seasonal distributions of dissolved iron, manganese and cobalt in the Northeast Atlantic continental margin.
Decline of the anthropogenic lead imprint to the ocean confirmed by data from the South West Atlantic Ocean
This study reveals that the mean lead concentrations in the surface waters of the western South Atlantic Ocean decreased by 34 % between the 1990s and 2011.
Irradiance-normalized non-photochemical quenching (NPQ): a new proxy of iron stress for phytoplankton
Ryan-Keogh and his colleagues used NPQ to fingerprint the photo-physiological response of phytoplankton to their environment.
Exhaustive modelling study of the oceanic neodymium parameters
The conclusion of this study reinforces the important role of the solid particles in driving the neodymium oceanic cycle.
Dissolved manganese distribution in the Arabian Sea reveals many variable triggers
Analysis of dissolved manganese on samples collected on GEOTRACES cruises allowed Singh and colleagues to establish its basin-wide distribution in the Arabian Sea.
Dissolved iron II deep concentrations re-estimated considering oxidation kinetic effets
Gonzalez-Santana and his collaborators demonstrated that the oxidation kinetic of the samples combined with analysis of triplicate subsamples led iron (II) concentrations to decrease with time.
Do you want to know more about iron and its isotopes? This review is for you!
Authors present a comprehensive review of iron and iron isotope sources, internal cycling, and sinks in the ocean.
Actinium-227 distribution traces at least three processes in the North Atlantic Ocean
Le Roy and colleagues report an oceanic section of Actinium-227 in the North Atlantic Ocean.
Transient tracers, water mass ages and mixing time scales in the Arctic Ocean
Smith and colleagues determined iodine-129, chlorofluorocarbons and sulfur hexafluoride during three GEOTRACES cruises in the Arctic Ocean.
