GEOTRACES are seeking a postdoctoral researcher who will be in charge of undertaking careful dissolution experiments of sedimentary and hydrothermal particles, on the recently funded ANR project entitled “BIIM” (Biogeochemical Impact of Iron released by Marine particles of sedimentary and hydrothermal origin).
Analyses will include SF-ICP-MS (Element XR/SeaFAST), iron organic speciation by competitive ligand exchange adsorptive cathodic stripping voltammetry (CLE-ACSV) and SEM/XDS imaging. He/She will interpret the results regarding the parameters affecting the dissolution of iron from suspended sedimentary particles. He/she will be interacting with the modellers so that outputs of these experiments can be embedded in biogeochemical models. The end goal of this work is to produce an assessment of the global biogeochemical impact of iron particles on the dissolved iron distribution and variability that, in turn, will impact global biological production patterns.
Previous experience with trace metal clean analytical techniques is required. Excellent oral and written English and ability to work within a multidisciplinary team are compulsory. He/She is expected to publish the results in high-impact journals and participate to international conferences. Strong knowledge in trace metal biogeochemical cycles are required.
