Yesterday we’ve been at Mer Bleue, the bog near Ottawa where the research is happening. All kinds of sensors are installed to measure up-going air and composition; also one Eddy Tower.

The heart of Eddy Covariance in all its glory

The distinctive feature of a bog is, that nutrients and water are only coming with precipitation so its more or less cut off from the surrounding influences. Additional in this case water height is held by a beaver dam. These beavers! They seem to be very active and blocking all installed draining pipes with lots of effort. So we had to get our hands dirty to remove parts of the beaver dam. Its amazing what they do within one month. Since there are draining pipes installed in the dam the just build another barrage around the tube… Puh.
