Not funded by a EU programme Is the Job related to staff position within a Research Infrastructure? NoOffer DescriptionAnalysis and evaluation of geochemical data as part of the ANR COR-Resilience program. This involves processing and interpreting data already acquired from elemental and isotopic measurements taken from coral cores of the Porites and Diploastrea genera in the Indian Ocean, particularly those taken around Mayotte, Juan de Nova, and Europa.Using existing data sets stored in Excel spreadsheets, data analysis (trace elements & stable isotopes) will be carried out in order to reconstruct the interannual and decadal variability of temperatures and the chemistry of carbonates in coral calcification fluids over the last century for the sites studied. Once the calculations have been performed using existing proxies and calibration curves and appropriate computer tools, the data will be interpreted and the reconstructed environmental data will be compared with the evolution of the growth parameters of the corals studied (data also acquired). A comparative analysis of the response of each genus will be considered, taking into account the biomineralization processes currently known in the literature for tropical corals. Statistical analysis or modeling tools could be implemented in collaboration with experts from the COR-Resilience program. Finally, the activity will focus on writing scientific articles with the aim of submitting them for publication. Ideally, the goal is to write two articles.This position is part of the COR-Resilience program, and the successful candidate will work directly with experts from the laboratories involved in the program. This includes Florence Le Cornec (LOCEAN), Dr. Eric Douville (LSCE), and Dr. Paolo Montagna (CNR - Bologna, Italy) for the analysis of geochemical data from the corals studied, and Myriam Khodri (LOCEAN) & Marion Gehlen (LSCE) for the “modeling” component and statistical data processing tools, as well as for their expertise in paleoclimatology and marine biogeochemistry.Expertise in marine biogeochemistry in tropical environments and climatologyKnowledge of ocean carbonate chemistryKnowledge of coral biology, calcification properties, and bioerosionComputer tools for data processing (Excel, R, Python, etc.)Office Suite (Excel, Word, PowerPoint, etc.)Independence, rigor, and analytical and writing skillsSpoken and written EnglishThe candidate must hold a PhD in Climate and Environmental Sciences with 1 to 2 years of postdoctoral experience and possess the following skills:
