NENCKI INSTITUTE RESEARCH STATION – MIKOŁAJKI 
April 30th, 2016 we hosted at the Hydrobiological Station a famous traveler, photographer, blogger, speaker at many travelers festivals (Kolosy) – PIOTR HORZELA, who traveled by various means of transportation through the all climatic zones on several continents. We went with him on the exotic journey “Under the African sky“, to a geographically and culturally remote Southern Sudan, where he lived and worked for two years (TJ).
