Mellett and Buck present the concentrations of bioactive trace metals (Fe, Cu, Mn, Zn, Co, Ni, Cd, and Pb), Fe-and Cu-binding organic ligands, and electroactive Fe-binding humic substances in the eastern Gulf of Mexico.

Zinc
Informative zinc isotopic fractionation in the Southern Ocean
Ellwood and co-workers (2020, see reference below) established the distribution of dissolved and particulate zinc (dZn and pZn respectively) and its isotopes in the Subantarctic Zone South of Tasmania. Concentration […]

Artificial intelligence helps investigate the oceanic zinc cycle
What explains the hitherto mysterious correlation between zinc (Zn) and silicon, an element not involved in the Zn cycle? Roshan and co-workers (2018, see reference below) used an artificial neural […]

Dissolved zinc and silicate decoupling in the North Pacific Ocean
Large-scale distributions of dissolved zinc (Zn) in the western and central subarctic North Pacific Ocean was established as part of the North Pacific GEOTRACES section GP02. Kim and co-workers could […]

A new method for simultaneous analysis of nickel, copper and zinc isotopes in seawater
Takano and co-workers (2017, see reference below) have developed a new method to determine nickel (Ni), copper (Cu) and zinc (Zn) isotopes in seawater. This method is very simple and […]

The coupled zinc-silicon cycle paradox illuminated
The strong similarities between zinc (Zn) and silicon (Si) vertical profiles have led many studies to suggest the uptake of Zn in diatom frustules, followed by simultaneous remineralisation at depth. […]

Hydrothermalism: a major contributor to the oceanic inventory of dissolved zinc
High-quality dataset of dissolved zinc (Zn) from the US GEOTRACES EPZT cruise (GP16 section) allows Roshan and co-workers (2016, see reference below) to revisit the oceanic budget of dissolved Zn. […]

Onboard analysis of dissolved zinc everywhere in the open ocean with a Lab on Valve (LOV) system of the size of a bottle of wine is becoming possible
Thanks to the work of Maxime Grand and collaborators (2016, see reference below), it is now possible to analyse dissolved zinc (DZn) on board, from any kind of seawater using […]

Decoupling between dissolved zinc and silicon in the North Atlantic Ocean driven by mixing of end-members
Roshan and Wu (2015, see reference below) reveal that the correlation between dissolved zinc (Zn) and silicon (Si) is relatively weak in the North Atlantic Ocean (GA03 US section). They […]
