The subprogram, Macro Fauna Soft Bottoms, contains trend and aerial monitoring of soft-bottom fauna in the Gulf of Bothnia. It is conducted by Umeå Marin Research Center (UmU-M) and includes basic sediment investigation and assessment of oxygen concentration in bottom waters. The aim is to observe if, and in what way, the structure of the bottom macro fauna changes. Changes may indicate over-fertilization and oxygen stagnation. Embryogenes of Amphipod (Monoporeia affinis and Pontoporeia femorata) and its environment is studied at 7 sites in Baltic Proper and 5 sites in Gulf of Bothnia as an indicator species of bottom sediment quality.
