This section presents the GEOTRACES scientific activities.
Interaction of the currents with the sediments deposited on the margins of the Crozet Islands (Southern Ocean) contributes to the supply of iron and other micronutrients to marine waters. This […]
Iron (Fe) is an essential trace element for marine life. Extremely low Fe concentrations limit primary production and nitrogen fixation in large parts of the oceans and consequently influence ocean […]
The relative importance of four different dissolved iron (Fe) sources in the North Atlantic Ocean have been precisely determined for the first time thanks to GEOTRACES. Using a novel method […]
Using model simulations, Tagliabue and co-authors (2014, see reference below) tested the sensitivity of the ocean to absorb the atmospheric carbon dioxide (CO2) in response to variable supply of iron. […]
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 […]
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 […]
Contact: Maite Maldonado (University of British Columbia, Canada). Trace elements are essential for many metabolic pathways. Furthermore, biological activity can have profound effects on the distribution and speciation of trace […]
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 […]
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 […]
