On April 25th, 2013 the Rostock "Night of Science" took place. The Marine Science Center invited everybody to join between 6 - 10 pm. Our guests were able to watch our experiments directly. At the same time fascinating underwater pictures of our seals were generated in cooperation with the scientific divers from the University of Rostock and presented in our seminar room. Scientists were informing our guests about the scientific work at the Marine Science Center as well as about scientific diving.
