OXY (Internal nutrient loading reduction by artificial oxygenation in the Gulf of Finland)

Organisation: Pöyry Environment Oy

Time: 5/1/2009 – 5/1/2011



Contribution to the development of the oxygenation projects in selected areas of the Baltic Sea in order to reduce the internal loading of nutrients of the reduced sediment surfaces. The project requires identification of the suitable areas for artificial oxygenation based on experienced method used widely in the inland lakes of Finland and in the Pojo Bay, evaluation of the achieved benefits, planning of the implementation, searching and developing of funding mechanism for implementation of the selected projects.

Long term internal nutrient load reduction to improve and maintain the ecologically acceptable conditions in the Baltic Sea while there are other ongoing and future efforts to reduce the external loading e.g. from agriculture and wastewater treatment sources around the Baltic Sea coast.
