The Baltic Sea is in many ways a unique research subject – at the same time, it is a young sea, but also one of the busiest and most polluted seas in the world. It has been called a laboratory, a time machine, and a pilot, as the conservation methods that have been developed for the Baltic Sea are applicable around the world. At the University of Turku, biologists, geographers, historians and researchers in natural sciences and maritime spatial planning are focusing on the current challenges. Six researchers reveal how their research aims to improve the state of the Baltic Sea.

In Finland, the majority of the glacial and warm interval records have been interpreted to represent only the last, Weichselian, glacial cycle that took place 11,700–119,000 years ago. Finnish researchers have now revised the crucial part of the existing stratigraphic documentation in southern Finland. The new findings show that a considerable part of the warm interval records extends further back in time than earlier thought. The new results change the established conceptions about glacial history in the area.
