Some recent GEOTRACES science findings are reported below.
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.
Ryan-Keogh and his colleagues used NPQ to fingerprint the photo-physiological response of phytoplankton to their environment.
The conclusion of this study reinforces the important role of the solid particles in driving the neodymium oceanic cycle.
Analysis of dissolved manganese on samples collected on GEOTRACES cruises allowed Singh and colleagues to establish its basin-wide distribution in the Arabian Sea.
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.
Authors present a comprehensive review of iron and iron isotope sources, internal cycling, and sinks in the ocean.
Le Roy and colleagues report an oceanic section of Actinium-227 in the North Atlantic Ocean.
Smith and colleagues determined iodine-129, chlorofluorocarbons and sulfur hexafluoride during three GEOTRACES cruises in the Arctic Ocean.
Understanding the key processes that condition the net input of chemical species to the ocean is an important challenge…
