(1) Organization of field work, (2) physico-chemical analysis of mudflat sediment and pore water (3) statistical analysis of results, (4) interpretation, discussion and exploitation of results (conferences, writing articles and reports)
Determination of benthic fluxes and pore water profiles of N and P nutrients of different types of sediments on mudflats affected by macroalgae blooms; determination of sediment typology related to the molecular composition of organic matter and potential nutrient fluxes.
The candidate will have a thesis in the field of biogeochemistry or environmental analytical chemistry. Knowledge about the biogeochemistry of coastal sediments and the nitrogen (and phosphorous) cycle would be a plus. The candidate will have good organization skills and experience with field campaigns as well as experimental and analytical laboratory work. The candidate must demonstrate his ability to process and publish data in English as scientific articles. Finally, a necessary skill is the capacity for teamwork.
The role of coastal mudflat sediments on the fluxes of dissolved nutrients is poorly understood. However, the functioning of this buffer zone at the interface between terrestrial and marine nutrient fluxes is of large interest. The mineralization of organic matter and the release of nutrients from the mudflats to the water column is expected to have an impact on the development of green algae in the coastal zone. In order to get a better understanding of benthic N and P fluxes and their role in the development of green algae on mud flats in Brittany (France), the research project "IMPRO" funded by the “region de Bretagne” and the “agence de l'eau Loire et Bretagne” will start in March 2019. Within the framework of this project we are looking for a research engineer to study the spatial variability, at the scale of Brittany, determining the relation between (i) benthic nutrient fluxes, (ii) the composition of the organic matter and (iii) the occurrence of macroalgae. The proposed task includes the sampling campaign, the biogeochemical analyzes of the mudflats, the benthic flux measurements as well as the interpretation and publication of these data.
