On 16 February 2015 scientists from GEOMAR conducted a one-day cruise to the Bay of Kiel with the research vessel ALKOR. There they took several sediment cores. The aim of the study is to learn more about the so-called Kiel lake, a former freshwater lake which was flooded by the modern Baltic Sea about 8000 years ago.
