Dear Peatland Colleagues,
Even if it is still some time until the EGU2016 General Assembly, 17-22 April, (and a winter in between in the northern Hemisphere) we would like to invite you to submit an abstract to the session “Peatlands under pressure” (BG4.2/SSS9.24, http://meetingorganizer.copernicus.org/EGU2016/session/21879). Abstract deadline is 13 January 2016. Hope to see you there Annalea Lohila & Eeva-Stiina Tuittila, Mats Nilsson, Leif Klemedtsson, Juul Limpens Session description: From pole to pole, peatlands contain up to 30% of the world’s soil carbon pool, illustrating their role in the global carbon cycle. Currently peatlands are under various pressures such as changing climate, land-use or nutrient loading with unknown consequences for their functioning as carbon sinks and stores and the uptake or release of the greenhouse gasses carbon dioxide (CO2), methane (CH4) and nitrous oxide (N2O). Simultaneously, increasing amount of restoration activities, aiming to return peatlands back to their original state are ongoing. It is, however, not clear how the carbon reservoir will react to these pressures and how resilient these ecosystems are. This session will focus on the observed or predicted changes on the biogeochemistry at peatlands, caused by climate change, nutrient loading or land-use. We invite studies concentrating, for example, on the effects of climate change on GHG flux or nutrient dynamics on pristine and managed peatlands, impact of drainage or restoration and subsequent vegetation succession on biogeochemistry, atmosphere-biosphere interaction, or studies on carbon stock changes demonstrating the impact of land-use or climate change. Both experimental and modeling studies are welcomed.

Your timing is perfect, we were just thinking of keynote speakers! So, I will add your name in the session advert. Annalea "Nigel Roulet, Prof." <[email protected]<mailto:[email protected]>> kirjoitti 20.11.2015 kello 1.11: Annalea and company: I have been invited to give a talk in a hydrology of peatlands session. I notice that you guys have put a session together on peatlands under pressure. I am in the process of finishing a paper on the sixteen year carbon balance of Mer Bleue. Mats knows I have been looking at the resilience in MB and we know have a long enough data set to show that the inter annual variability is strongly correlated with the mean and minimum growing season water table. If we look at the theory of peatland stability this is what one would expect. So it looks like MB, while subject to considerable pressure will be able to maintain its NECB. Would you guys be interested in a paper on the long-term NECB and what it tells us about the sensitivity (or lack thereof) of raised bogs to climate change? nigel ___________________________________________________________ Nigel T.
