Greenhouse Gas Balance at Degraded Peatlands in Temperate and Mediterranean Europe

Rewetted Peat Extraction Site Himmelmoor Near Hamburg

Christian Wille explaining the eddy covariance system installed in Himmelmoor.

The managed bog 'Himmelmoor' is located 21 km NW of the Institute of Soil science and the centre of Hamburg. The peatland was used for peat mining for several decades with a strong mechanisation since the last 50 years. Nowadays, the peat mining is still active, but approximately 50 % of the area is now out of usage and will be restored in the coming years. For our project, the change from an intensively mined peatland to a near-pristine ecological system is of high interest. Particularly, we are interested how and why the exchange of energy, water and trace gases will change in response to the rewetting of the peatland. In 2011, we installed an eddy covariance tower to measure the fluxes of energy, water, carbon dioxide and methane. Additionally, we plan to conduct closed chamber measurements to improve our knowledge on the microscale variability of trace gas fluxes.

Besides our research at the 'Himmelmoor', we use the field site for education of bachelor and master students. Our aim is to educate students in the whole range of ecosystem sciences related to flux measurements. This includes technical training at the different instruments, management of complex datasets and mathematical as well as statistical analyses.

The 'Institute of Soil Science' and our CliSAP Research Group 'Regional Hydrology of Terrestrial Systems' cooperates closely with the LI-COR Biosciences GmbH. As partners, we work together to train students and scientists in the field of the eddy covariance methodology.
