The sea - it separates and connects, has been an inspiration for poets and a challenge for scientists, a salty desert and in the same time a habitat of astonishing living creatures, starting point for migrants and conquerors, place for recreation and struggle to survive. Students from different seasides in Europe (Black Sea, the Atlantic, the Mediterranean) will work in a cross-curricular and cross-cultural manner on various aspects of the topic 'sea'; they will combine natural sciences and humanities and they will present results of their research using both scientific and creative activities.
