Caption: This image shows measuring equipment in Rylekæret fen, Zackenberg. The lawn-chair-like devices at the end of the boardwalk measure the exchange of methane and CO2 between the fen and the atmosphere. To the left is: a gradient system for measurement of the exchange of methane between the tundra and the atmosphere. Even though many of the measurements can now be made automatically, it is necessary to check the equipment regularly to ensure that everything is in good working order.
