The second day of the EACH Winter school was full of excitement.
The key event of the second day was dissolved oxygen intercomparison between the student teams. The samples were water samples from the nearby lake Pühajärv. The student teams used optical oxygen sensors (based on luminescence), see the photo on the left. The seriousness of the intercomparison is underpinned by the independent reference values determined using the highly accurate primary Winkler titration procedure (developed by Irja Helm in her PhD thesis).
The results of the intercomparison will be summarized at the closing of the Winter school.

On the right you can see the group photo (Lake pühajärv is behind the trees) taken right after the lunch and followed by a spontaneous snow fight (photo on the left) where the “African team” (Ime and Olivier, in the centre) performed stunningly well in comparison to the Nordic snow fighters!

The consortium committee spent most of the day interviewing students and discussing (including negotiations with university officials about maximum possible numbers of students) for distributing students to study tracks. The day ended with the long-awaited announcement that it will be possible to grant every student the preferred study track!
