Science Highlights

Some recent GEOTRACES science findings are reported below.

Undocumented cadmium, zinc and copper sink in oxygen minimum zones

Cadmium (Cd) is a micronutrient for marine algae and has a marine distribution similar to the macronutrients nitrate and phosphate. The use of sedimentary microfossil records of Cd, thus, allow […]

Copper and zinc oceanic mass balance revisited

Little and co-workers (2014; see reference below) propose an update of the oceanic copper (Cu) and zinc (Zn) mass balance, with the original approach that takes into account the hitherto […]

Latest discoveries about zinc concentrations and isotopes in the ocean

Zinc (Zn) is an essential micronutrient for phytoplankton and plays a key role in the productivity of the oceans. Despite the importance of this element, the processes which govern its […]

What does the largest data set of zinc concentration ever reported tell us?

Zinc (Zn) is one of the key micronutrients that are measured during the GEOTRACES cruises. N.J. Wyatt and colleagues (2014; see reference below) largely contributed to this collective effort by measuring Zn […]

Sinking organic matter: a major driver of the oceanic zinc cycle?

Zinc (Zn) is a marine micronutrient, important for phytoplankton and involved in biogeochemical cycling throughout the oceans. Despite the importance of this element, the processes that control the oceanic Zn […]

First full depth profiles of zinc isotopes in the ocean, thanks to IPY/GEOTRACES cruise (GIPY5)

Three major and original features are deduced from the first three full depth profiles of zinc measured by Zhao and co-workers (2014; see reference below) in the Southern Ocean: below 1000 […]

When atmospheric dynamic controls the nutrient distributions in the ocean

Rainfall detection with satellites together with high-resolution data (~0.3°) for dissolved iron (DFe), aluminium (DAl), and inorganic phosphorus (DIP), confirm the existence of a sharp north–south biogeochemical boundary in the […]

First results from platinum reference samples published

In Cobelo-García and co-authors work, data on platinum (Pt) concentrations in SAFe and GEOTRACES reference samples is reported for the first time. The paper also provides helpful information for those […]

GEOTRACES: Changing the way we explore ocean chemistry

Read about the experiences and lessons learned in the planning and implementation of GEOTRACES international programme in a recent paper published in Oceanography. Anderson and co-authors present an extraordinary synthesis of […]
