"Nuskendusi Žemė" - is an underwater journey into a world that no longer exists, yet still lies hidden in the dark depths of the Baltic Sea — at a depth of 30 meters. Covered by sand and shrouded in darkness are forests that grew here 12,000 years ago — pines and oaks. The scientist's goal is to discover entire areas of these ancient forests, collect samples, and determine the origin and age of these trees through laboratory analysis. This is an important scientific discovery that reshapes our understanding of the history of the Baltic coast and the people who once lived here.
