Analysis
Using ICPMS/MS to determine manganese, iron, nickel, copper, zinc, cadmium and lead concentrations on less than 40ml of seawater
Jackson and co-workers (2018, see reference below) first did a classical offline preconcentration of small seawater aliquots using a SeaFast system. More innovative is the use of a state of […]

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 […]

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 […]

An example of a fruitful international intercomparison
The reliability of the GEOTRACES data products including the eGEOTRACES Electronic Atlas is strongly related to the quality of the data acquired by the different laboratories contributing to this international effort. A […]

All mercury species measured along the GEOTRACES-UK section, South Atlantic Ocean
Total mercury (THg), methylated mercury (MeHg), and dissolved gaseous mercury (DGM) concentrations were determined along 40°S in the Atlantic Ocean. All Hg species had higher concentrations in western than in […]

Important warning about the uncertainties affecting results of dissolved iron concentration measurements in seawater using flow-injection with chemiluminescence detection
Flow-Injection with Chemiluminescence (FI-CL) is a procedure commonly applied in the framework of the GEOTRACES cruises because of its portability and hence suitability for shipboard deployment. Following the Guide for […]

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 […]
