Results from the first US-GEOTRACES cruise in the North Atlantic are coming out! Andrew Wozniak and co-authors show that aerosols from European-influenced air masses (combustion influenced) have higher relative iron (Fe) […]
Surprisingly high dissolved iron (dFe) values have been found in the subsurface oxygen minimum waters of the tropical North Atlantic from the Cape Verde Islands west to 42°W, reaching concentrations […]
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 […]
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 […]
Some phytoplankton species have the capacity to modify surface water arsenic speciation, inhibiting its toxicity. Such detoxification is operative in oligotrophic waters when phosphate concentrations are below those for arsenic […]
The African coast appeared to be a major source of dissolved total dissolved cobalt, iron, manganese, and labile cobalt to the South Atlantic basin, with high cobalt concentrations in the […]
Scientists participating in GEOTRACES have developed a new strategy to evaluate trace element fluxes to the ocean from aerosols (Hsieh et al, 2011). The new approach uses the common geochemical behaviour […]
