A review constituting the half-way mark of GEOTRACES
After a brief reminder on the motivation and foundation processes of the international and ambitious programme GEOTRACES, Bob Anderson (2020, see reference below) proposes an overview of many results of […]

Welcome to the first Korean participation in GEOTRACES
Thanks to the newly launched research vessel (R/V) Isabu of the Korea Institute of Ocean Science and Technology (KIOST), and the acquisition of a contamination-free PRISTINE (NIOZ, NL) ultraclean seawater sampling system […]

About the decoupled fates of aluminium, manganese, cobalt and lead in the North Pacific Ocean
Did you know that each of these tracers could follow its own marine story, quite decoupled from the others? This is what is shown and discussed by Zheng and co-workers […]

On the optimal use of the seaFAST system
Do you wish to improve your recoveries, blanks or any other parameter of your seawater preconcentration system (seaFAST)? Or are you simply curious about it? Wuttig and co-workers (2019, see reference […]

All the bioactive elements are not affected by the land-ocean gradient of the atmospheric deposition along the Eastern Pacific Zonal Transect
Atmospheric dust is considered an important source of trace elements to the ocean. As part of the Eastern Pacific Zonal Transect GEOTRACES cruise (EPZT GP16), Buck and co-workers collected 17 […]

The residence times of trace elements determined in the surface Arctic Ocean during the 2015 US Arctic GEOTRACES expedition
Data collected during the US Arctic GEOTRACES expedition in 2015 (along GEOTRACES section GN01) were used to estimate the mean residence time of dissolved trace elements (iron-Fe, manganese-Mn, nickel-Ni, cadmium-Cd, […]

Has the role of atmospheric dust as a control on productivity in oligotrophic regions been overestimated?
Dust particles settling into the surface of open ocean environments are for years assumed to provide nutrients to these distant nutrient-limited areas. Torfstein and Kienast (2018, see reference below) present […]

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 […]
