The Finnish Environment Institute monitored the state of Finland's marine areas in August. The sea bottom in the deep parts of the Gulf of Finland were oxygen depleted, and the oxygen situation of the deep bottom areas of the coast had deteriorated, which was also reflected in higher levels of phosphate phosphorus and reduced numbers of benthic animals. The oxygen and benthic animal situations are clearly better in the Archipelago Sea than they are in the Gulf of Finland.
