We have ended the KAWater mesocosm experiments at Lake Erken! We had three exciting years of sampling, trying things and sometimes fail. Now we have accumulated a lot of samples, some of them processed and some of them still waiting to be analyzed. I am looking forward for the interesting things we will learn from these experiments, but we have finalized one big step and that is the actual sampling. Many, many hands have helped during these campaigns. Thank you so much to the great KAWater team! Without your work, sweat, patience and endurance, this project would not be possible!
