Some recent GEOTRACES science findings are reported below.
The central Baltic Sea is a marginal brackish basin, in which anoxic bottom waters prevail either seasonally or permanently and which is surrounded by continental landmasses comprising a large variety […]
Measuring concentrations of many constituents at the nano- to picomolar levels in seawater is a difficult challenge, requiring thorough intercalibration between the different laboratories participating to the same programme. GEOTRACES is […]
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 […]
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 […]
The first simultaneous method for the determination of these three isotope systems in seawater has been published. This method is designed for use on only a single litre of seawater […]
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 […]
Using Radium-228 (228Ra) activity as an indicator of coastal water mass influence and a compilation of Neodymium (Nd) parameters in the first 100 m, Chen and co-authors propose that more stratified […]
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 […]
Analysis of osmium in seawater presents complex challenges, linked to its very low (femtomolar) concentrations and multiplicity of possible oxidation states. Early insights were provided by Karl Turekian’s group at […]
