– Water masses traced by neodymium isotopic compositions at an unprecedented level in the North Atlantic Ocean
 |
As part of the Dutch GEOTRACES GA02 section, Myriam Lambelet analysed neodymium (Nd) isotopic compositions and concentrations at 12 profiles in the North West Atlantic Ocean, extending from the south of Iceland down to the Sargasso Sea…

– 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…

– When a multi-parameter end-member mixing model allows a quantitative deconvolution of the dissolved rare earth elements behaviour
 |
The dissolved Rare Earth Elements (dREE) data discussed by Zheng and co-workers have been collected along a full depth section at 12°S in the South Atlantic Ocean, using a new high-precision analytical protocol…

– What do the first 236-Uranium data reveal in the Arctic Ocean?
 |
Casacuberta and co-authors propose the first set of data for the artificial radionuclide 236-Uranium in the Arctic Ocean. The novelty of this study compared to the first comprehensive dataset they published in the western North Atlantic Ocean, is the combination of 236-Uranium with 129-Iodine…

– Major presence of GEOTRACES at Ocean Sciences Meeting 2016
GEOTRACES had, once again, a large and successful presence at the Ocean Sciences Meeting 2016 (21-26 February 2016, New Orleans, Lousiana, USA).
The GEOTRACES sessions (including 56 orals and 88 posters presentations), the Town Hall “Strengthen your Science (and Proposals) using GEOTRACES Data” and the tutorial “What Controls the Distribution of Dissolved Iron in the Ocean” were well-attended showing the success and the ocean research community interest in the programme.
In addition, GEOTRACES shared a booth with other international projects of the Scientific Committee of Oceanic Research (SCOR). GEOTRACES Scientific Steering Committee members and the International Project Office staff were available to inform visitors about the programme and provide GEOTRACES materials. A video documenting GEOTRACES research activities was played at the booth. Discover it here!
