| Summary: | Climate change is causing temperatures in the Arctic to rise faster than in any other region of the world. This rapid warming leads, among other effects, to the massive loss of ice masses, development of thermokarst features when permafrost thaws, intensification of the hydrological cycle, and increasing loads of nutrients and organic carbon to surface waters. Freshwaters are highly sensitive to these changes, which affect microbial community composition and diversity. Therefore, these ecosystems are good sentinels to study processes in primary ecological succession related to ecosystem processes such as productivity and greenhouse gas (GHG) emissions. With this study, we aim to contribute to a deeper understanding of the linkages between biogeochemistry and hydrology in High Arctic freshwaters. To this end, we sampled various water sources (e.g., lakes and streams) in two High Arctic catchments (Bayelva and Lovénbreen, in Svalbard in July 2021) for the analysis of GHGs (CH4, CO2, N2O), noble gases ... : EGUsphere ... |
