Some recent GEOTRACES science findings are reported below.
Takano and co-workers (2017, see reference below) have developed a new method to determine nickel (Ni), copper (Cu) and zinc (Zn) isotopes in seawater. This method is very simple and […]
Dissolved silicon (Si) is a major oceanic nutrient and variations of its stable isotope values are reflecting the intensity of surface primary production. As for other isotopes, agreement between the […]
Subarctic Pacific is known as High Nutrient, Low Chlorophyll (HNLC) area, where phytoplankton growth is limited by dissolved iron (DFe) availability. The biological activity in the surface waters is also […]
Which paleo information are traced by the imprint neodymium isotopic signatures (εNd) in the different archives: paleo circulation or paleo erosion? The scientific debate on this issue is opened for […]
Dissolved thorium (Th) isotopes and iron (Fe) are used to document the transfer of lithogenic material to the ocean. Two contrasting areas are compared: the Atlantic Ocean around Barbados Islands, […]
The striking extension of the dissolved iron and manganese plumes over more than 4000 km from their hydrothermal sources along the US GEOTRACES East Pacific Zonal Transect (EPZT) cruise (GP16) has […]
Tagliabue and co-workers (2017, see reference below) discuss an extensive review on the recent findings on iron (Fe) cycle in the ocean. They figure out clearly that: Fe is a […]
Boyd and co-workers (2017, see reference below) explore the abiotic and biotic mechanisms that underpin internal metal cycling. Although they are focusing on iron (Fe) as the best-characterized metal, they […]
Phytoplankton development is strongly linked to the dissolved iron availability in the surface waters. Iron’s behavior is sensitive to warming, stratification, acidification and de-oxygenation. In a changing ocean, these processes […]
