- All mercury species measured along the GEOTRACES-UK section, South Atlantic Ocean
Total mercury (THg), methylated mercury (MeHg), and dissolved gaseous mercury (DGM) concentrations were determined along 40°S in the Atlantic Ocean. All Hg species had higher concentrations in western than in eastern basin, although they are at the ultra-low femtomolar level...
- Amazingly detailed compilation of the silicon cycle, with an emphasis on the oceanic silicon isotope budget
Although this article is not resulting from GEOTRACES activity, its content is definitely GEOTRACES relevant. The authors constructed an up-to-date compilation of the continental silicon (Si) cycle, including the fate of Si isotopic composition in the different continental but also estuarine and marine solid and solutions...
The GEOTRACES Scientific Sterering Committee (SSC) welcomes Zanna Chase (University of Tasmania, Australia), Adrian B. Burd (University of Georgia, USA) and Eric Achterberg (GEOMAR, Helmholtz Centre for Ocean Research, Germany) as new members.
Thank you to Andrew Bowie, Olivier Marchal and Angela Wagener who rotated off the GEOTRACES SSC after six years, for their time and effort as members of the SSC.
- New S&I co-chair
Walter Geibert (Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research, Germany) has been named co-chair of the GEOTRACES Standards and Intercalibration (S&I) Committee.
Thanks to Greg Cutter, former co-chair, for his service over the past years. Greg has played an exceptional role in launching and driving the S&I. An enormous task that greatly served GEOTRACES!
The Integrated Marine Biogeochemistry and Ecosystem Research (IMBER) project has developed a new Science Plan and Implementation Strategy, to guide the next decade of research into marine biogeochemistry, ecosystem structure and functioning, the human dimensions of global marine change, and interactions between each of these...
