Long-term series of hydrographic and biological data show the Slupsk Furrow to be the only Baltic deep area devoid of H2S, its bottom being inhabited by a number of marine species not found in other Baltic deeps (Bornholm, Gdansk, and Gotland Deeps). For this reason, it is necessary to grant the Slupsk Furrow the status of a marine protected area as a habitat and refuge of species absent in other Baltic Proper deeps.
