Colloquium on “Future Directions in French Polar Pollution Research”, Toulouse, 14-15 October 2019


The aim of the meeting is twofold. First, to highlight recent and on-going research on the topic of pollution in Polar Regions (Arctic and Antarctic). Second, to discuss the needs, priorities and future directions of the French research on polar pollution with the aim to write a short “position paper” after the meeting. The meeting is thus open to a wide community interested in pollution issues and will cover the different topics identified in the French deliverable to the second Arctic Science Ministerial : Pollutants and Climate, Pollutants and Biogeochemistry, Pollutants and Society, and Pollutants and Ecology. Each session will include keynotes, scientific presentations (oral and poster) and a round table. The latter includes an open discussion about the future format, contours and organization of French research on polar pollution as well as opportunities for funding, new collaborations and contributions at national and international levels. The meeting will be inter-disciplinary and involve researchers from multiple CNRS (INSU, INEE, INSHS and INC) and other institutes.
