– The power of GEOTRACES: a 3D animation example of Thorium-230 along GEOTRACES North Atlantic sections
 |
The central component of GEOTRACES is a series of cruises spanning the global ocean. These cruises collect water and analysis of many trace elements and isotopes. The power of the GEOTRACES field work is demonstrated by an example of 3D animation resulting from data collected on GEOTRACES North Atlantic cruises…

– GEOTRACES scientists discover new variability in iron supply to the oceans with climate implications
 |
Researchers based at the National Oceanography Centre Southampton (UK) and at the University of South Carolina (USA) have found that the amount of dissolved iron released into the ocean from continental margins displays variability not currently captured by ocean-climate prediction models…

– Latest recommendations for successful analysis of dissolved osmium in seawater
| |
Analysis of osmium in seawater presents complex challenges, linked to its very low (femtomolar) concentrations and multiplicity of possible oxidation states… Peucker-Ehrenbrink summarize the latest insights for successful analysis of dissolved osmium in seawater…

– Tracking the Indian Ocean source of barium
 |
Intermediate waters of the Bay of Bengal can be a significant source of dissolved barium (Ba) to the Indian Ocean. This is the conlusion of an extensive study of the dissolved Ba distribution along a north-south section in the Bay of Bengal conducted by Satinder Pal Singh and co-workers…

– Are the mid oceanic ridges a source of radiogenic neodymium input?
 |
An unexpected radiogenic value of neodymium (Nd) isotopic composition observed by Catherine Jeandel and colleagues in the Deep Pacific Water raises the question of the role of mid ocean ridges in modifying the oceanic Nd signature.

– Determining simultaneously iron, zinc and cadmium isotopes in small volumes of seawater is possible now!
 |
The first simultaneous method for the determination of these three isotope systems in seawater is published now. This method is designed for use on only a single litre of seawater representing a 1–20 fold reduction in sample size…
