Postdoctoral Fellowship in the Sentinel North Research Chair in Aquatic Geochemistry




The SN Research Chair in Aquatic Geochemistry is part of Canada's largest northern research initiative at Laval University. We invite applications for a postdoctoral internship that will take part in the Chair's Arctic research program in aquatic biogeochemistry. The program has a special interest in the feedbacks between environmental change and the dynamics of carbon, oxygen and other key elements in lakes, thaw ponds and rivers across the northern landscape. The program is located in the department of Chemistry at Laval University, in Quebec City, Canada, and the Takuvik International Laboratory jointly of the CNRS at Laval University. The successful candidate will be co-advised by Prof. Raoul-Marie Couture (Chemistry) and Prof. Warwick F. Vincent (Biology). The fellowship will be for one year, potentially renewable.

The project aims to resolve the sources and sinks of carbon and associated elements such as P, N, S and Fe in High Arctic lakes under changing redox conditions. The project will benefit from, and improve upon, existing data streams of high-frequency measurements in a range of lakes, from moored instruments and associated land-based stations operated by the Center for Northern Studies. The candidate will have access to extensive time-series and be responsible for their publication in data journals as well as their interpretation in the context of global change and its impacts on Arctic lakes. The candidate will also contribute along with our teams, to the planning and execution of field campaigns in the High Arctic that will aim to sample lake water column, sediment and pore water to quantify solid and aqueous phases of the elements of interests. Of particular interest will be the role of light and microbial metabolism in controlling the fate of elements across environmental gradients. As such, an interest and availability for field work, as well as a strong background in a relevant field (e.g., geochemistry, analytical or environmental chemistry, limnology) is required. Preferences will be given to applicants with a track record of research productivity in relevant natural sciences or engineering fields.

Sentinel North draws on over a half-century of northern research to improve our understanding of the northern environment and its impact on human beings and their health. Sentinel North is built around a major transdisciplinary research cluster that includes the Northern Research Institute (INQ), Amundsen Science, ArcticNet, the Takuvik Joint International Laboratory and the Center for Northern Studies (CEN).
