Dear colleagues,
this week's Biology Thursday seminar, 12:15 on Thu 6th of May (zoom link below) will be given by Professor Torben Røjle Christensen, Department of Bioscience, Arctic Research Centre: A long-term monitoring perspective on ecosystem-atmosphere interactions in the Arctic
Abstract: The exchanges of carbon dioxide (CO2) and methane (CH4) between arctic ecosystems and the atmosphere are sizeable and may if they change alter the further development of climate warming. These fluxes take place between the atmospheric background concentration of these trace gases and a very large reservoir of organic carbon stored in arctic soils and sediments. The stored carbon amounts to more than twice the current global atmospheric burden of CO2. Therefore, accurate measurements of the fluxes and how they vary temporally and spatially is key to understanding possible ecosystem impacts on the atmospheric concentrations and hence climate. This presentation will detail the current state of the global CO2 and CH4 budget and show examples of methods applied in quantifying the arctic trace gas flux components. The presentation will discuss data on how extreme events relating to ecosystem functioning (larvae outbreaks and extreme precipitation) can impact carbon fluxes.
Prof. Christensen is also the Scientific Leader of Greenland Ecosystem Monitoring project as well as the Scientific Leader Zackenberg Research Station, so this is a talk from the very top of Arctic research - don't miss it!
