From the 18th to 30th November 2019, I had a training in METLAKE research group of the Department of Thematic Studies – Environmental change, Led by Professor David Bastviken.  The training dealt with the construction of cheap sensors to use in the measurements of Carbon dioxide (CO2) emissions from aquatic ecosystems, their calibration, retrieving logged data and their analysis using python. I was also involved in the GHG-LAKE autumn 2019 field data collection.
