By many of us, the Baltic Sea is treated as a lifeless underwater desert, while in fact, the bottom zone is rich in flora and fauna. We will focus on zoobenthos, which includes organisms that dwell on the seabed regardless of whether they bury in sediments, walk on the bottom or simply just lie/sit on it. We will meet members of a few groups living in the Baltic – oligochaetes, polychaetes, molluscs and crustaceans. It is true however, that, due to periodic or permanent oxygen deficits, lifeless areas occur on the Baltic seabed. Oxygen depletion is mainly caused by eutrophication. Another significant environmental problems involve remnants after World War II that pollute the sea water. Will the pollution deprive the Baltic Sea of life? You will receive the answer during a webinar with educators from the Gdynia Aquarium.
The webinars are in English.
