DSC_0017New test of airborne microbial sampling with Federico at the Kolsass flux tower of Mathias Rotach (IMGI). This time we are sampling at two heights – fingers crossed that we see a gradient.

Field activities

Despite the snow, Biomet group members are active in the field:

Federico tested the impact of different integrated sampling times on bacterial DNA yields.

New study site and paper published

Today Kathi and Georg made the long drive to Lunz am See to set up an eddy covariance flux tower within the CarbEx project. Since the platform has been removed during winter, the flux tower as set up at the shore of the lake close to the Water Cluster Lunz in the meantime, before it will be moved to the platform in spring. The aim of the project is to link hydrological extremes to the carbon cycle of Lunzer See and the eddy flux measurements yield the lake-atmosphere CO2 flux.
