Anthropogenic disturbances to terrestrial and aquatic ecosystems occur regularly with land management practice, land use change and human-induced climate change being just a few examples. Evidence suggests that such disturbances may significantly impact greenhouse gas (GHG) exchange in the respective systems, e.g. farming practices after land conversion modifying nutrient availability in the ecosystem thereby altering the GHG budgets in nearby terrestrial and aquatic regions. With this session we aim at summarizing currently existing knowledge on deviations of GHG exchange of the three major GHGs, carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O), from terrestrial and aquatic ecosystems following ecosystem disturbance. Studies that focus on testing hypotheses, isolating mechanisms, specific processes, upscaling, technological advancement and identifying knowledge gaps are of particular interest. We aim to facilitate the interaction between the aquatic and terrestrial communities that study GHG budgets. Contributions presenting results on either ecosystem are encouraged, and we particularly invite studies bridging the gap between the aquatic and the terrestrial domain, e.g. catchment scale approaches. We specifically encourage for contributions from emerging new research infrastructures that focus on the biogeochemical cycles such as ICOS (Integrated Carbon Observation System), National Ecological Observation Network (NEON), Terrestrial Ecological Research Network (TERN), and others.
