Development of a sensors docking station for environmental monitoring in extreme environments

The climate warming currently affecting the Arctic is two to three times faster than anywhere else, with profound consequences for natural ecosystems and communities. Notably, thawing permafrost remobilizes organic matter (previously trapped in the soil) that underlies the production of greenhouse gases such as carbon dioxide and methane, which in turn helps amplify the ongoing greenhouse effect. On the other hand, the increased development of vegetation, a phenomenon called “Arctic Greening”, would instead lead to some capture of organic carbon in soils, although with significant heterogeneity between sites. What will be the Arctic region’s net balance: carbon sink or source? This is a fundamental question that has important implications for global climate modeling and, thus, for our resilience to the future impacts of climate change.
To answer this question, the Laboratoire Nanotechnologies et Nanosystèmes (LN2) aims to develop a docking station for aquatic sensors in order to follow-up physicochemical parameters in arctic lakes in Canada. This station will be tested during the summer of 2023 in northern lakes by a geologist from University de Sherbrooke. It will also be used to test specific sensors developed at LN2 to meet field scientists needs.
