Setup of an Eddy Station

The last week was busy since we were to set up a Eddy station. Although the station was supposed to be without an Gas-analyzer there was still enough to be done and prepared before heading out in the field. For two days I was building thermocouple temperature sensors which were to be inserted in the…

Eddy Covariance Principle

My work at Carleton University is connected with the learning of the Eddy Covariance method. The idea is to measure vertical fluxes in a atmospheric turbulent system. These fluxes are the exchange of our ecosystem with the atmosphere and are related to the general productivity of the ecosystem. But lets start at the beginning: Imagine…

Beavers!!

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 distinctive feature of a bog is, that nutrients and water are only coming with precipitation so its more or less cut off from…
