For all the participants of the expedition Lake Baikal is not only the deepest basin of fresh water on the planet but indeed a dream that became true. When people mention Baikal they usually say “My dream is to visit Baikal”. For the participants of the expedition Class@Baikal the dream became true with wonderful memories that make you wish to come back again. The offshore part of the expedition is over. Today we are preparing for tomorrow seminars when the participants of the expedition will present the work completed during the cruise. But Baikal is constantly in our mind and the memories, impressions and emotions are overflowing.
