Missions

The ISTO (Institut des Sciences de la Terre d'Orléans, http://www.isto.cnrs-orleans.fr/) laboratory is seeking a post-doctorate to work in an interdisciplinary team interested in the estimation of element fluxes and budgets in surface environments. The successful candidate will work on the relationship between the hydro-geochemical functioning and the carbon (C) cycle in peatlands (wetlands containing about a third of the world soil C). The works will consist in studying the biogeochemical and physical processes involved in the dissolved organic carbon (DOC) dynamics to better understand its spatio-temporal variability: qualitative and quantitative description of the processes (through observation and modelisation), interaction between C and nutrient cycles (especially N), improve scale change and coupling. The successful candidate will study the dynamics of the C cycle and the DOC fluxes with an integrated understanding of the peatland ecosystems, where the interfaces “water-soil-plants(rhizosphere)” play an essential role.

Activities

The postdoctorate will develop its research more specifically in the La Guette peatland in relation to the national and international running projects. In addition to the research work, the successful candidate will be involved 1) in the maintenance of the sensors (e.g. water table level), multiparameter sensors (organic matter fluorescence, turbidity, pH, conductivity) and the weather stations, and 2) in the collection, treatment and validation of the data and their implementation in the information system. These activities will be done in connection with sites and projects principal investigator. The postdoctorate will also participate to development of the in situ particulate organic carbon measurement.

Skills

The candidate must have a documented experience in writing and publishing scientific articles in international journals and show autonomy in her-his research and organization. It is expected that the successful candidate submits at least one article based on her-his results in an international peer-reviewed journal
The successful candidates should have 1) completed her-his PhD in in hydrology/hydro-geochemistry 2) a strong expertise in environmental sciences, 3) analytical skills (chromatographic and spectroscopic methods) and 4) field work skills.
The application form and has to contain: 1) a cover letter, 2)
a curriculum vitae, 3) reference of 2 significant publication, and 4) name and contact of 2 referents.

Work Context

The successful candidate will work in the Service National d'Observation (SNO) Tourbières (Peatland National Observation Service-France, at the Observatoire des Sciences de l'Univers en region Centre – OSUC, https://www.sno-tourbieres.cnrs.fr/), which is part of the French Reasearch Infrastructure OZCAR (Observatoire de la Zone Critique, Applications Recherche, http://www.ozcar-ri.org/ozcar/?lang=fr). The SNO Tourbières is composed of 4 sites instrumented to monitor hydrological and hydrochemical variables, GHG fluxes (CO2, CH4) and the vegetation cover. She-he will be part of the “Biogeosystèmes” team and under the responsibility of the scientific coordinator of the SNO Tourbières. The successful candidate will have to do missions in France and abroad. The deadline for application form submission is the 27th of February 2019.
