Information about legislation as well as national and international cooperation related to the Baltic Sea can be found on the Ministry of the Environment’s website. For more information about SYKE’s research and expert operations, please visit SYKE’s website. Information about marine environment planning is available at under the Living environment and planning heading.

Another important portal for marine-related information is Meriwiki, where anyone can set up an observation point, report an algae sighting or participate in discussions in the forum.

  • The new calculator shows how consumption contributes to nutrient pollution in the Baltic Sea 2017-02-03
    With the calculator developed by the Finnish Environment Institute and the Natural Resources Institute Finland, consumers can determine the impacts of their consumption habits on nutrient pollution in the Baltic Sea. Finland’s contribution to the nutrient pollution of the Baltic Sea is about 10 per cent. Food production accounts for about 60 % of the Baltic Sea footprint of an average Finnish consumer. Waste water is also an important source (about 25 %).
  • Underwater noise in the Baltic Sea a risk for fish and marine mammals 2017-01-25
    Underwater noise in the Baltic Sea has been measured for the first time. According to an international project led by the Finnish Environment Institute, the level of human-introduced underwater noise is increasing.
  • Smart Buoy will bring real time measurement of oil in Artic area conditions to oil spill response 2016-11-15
    The new smart navigation ice buoy system will deliver real-time data on oil in water especially in cold climate conditions. It will help environmental and oil response authorities to monitor marine environment more effectively
  • An extraordinarily extensive review of the Gulf of Finland’s status by three countries 2016-09-02
    The Finnish Environment Institute SYKE has published an assessment of the Gulf of Finland, compiling the research results of over a hundred Finnish, Russian and Estonian researchers. The over 300-page publication includes recent information on issues such as eutrophication, hazardous substances, invasive species, noise, maritime traffic, and plastic waste.
  • Major Baltic inflows have improved the condition of the Baltic Proper 2016-09-02
    The effects of the major Baltic inflows that have arrived in 2014, 2015 and 2016 can be seen in the improved oxygen situation of the basins to the east and south of Gotland. The anoxic area of the seabed in the Baltic Sea has become considerably smaller compared to the summer of 2014, but the inflows have nevertheless not been able to completely oxygenate the hydrogen sulphide-rich water in the depths of the Baltic Proper.
  • Incidence of cyanobacteria started early this summer, but towards the end of summer abundant cyanobacteria occurrences halted 2016-09-01
    Cyanobacteria started to increase in abundance early this summer, but during late summer less cyanobacteria surface blooms were observed than normally. In the Finnish southwestern open sea areas cyanobacteria were abundant throughout the summer, but mixed in the water column, and long-lasting surface blooms did not develop. In lakes, cyanobacteria were abundant only occasionally during the summer, but in August exceptionally little cyanobacteria was observed.
