On Baltic Sea Day, marine research and diverse marine nature are showcased onboard R/V Aranda and at Kansalaistori square
22.8.2025 12:10:58 EEST | Suomen ympäristökeskus | Press release
On Baltic Sea Day, August 28, as part of Helsinki Baltic Sea Festival, the marine research vessel Aranda opens its doors to the public at Pakkahuone Quay, near the Old Market Hall. Visitors can also explore Baltic Sea underwater biodiversity research at Kansalaistori Square, in front of Oodi Helsinki Central Library.

Research Vessel Aranda: marine research in practice
At the Pakkahuone Quay, R/V Aranda, managed by the Finnish Environment Institute (Syke), welcomes visitors to learn about Baltic Sea research activities and the vessel itself. Aranda is suitable for multidisciplinary research in the Baltic Sea and the world’s oceans; it has sailed both the North Atlantic and the waters of Antarctica. In addition to experts from Syke, experts from several other organizations will be onboard to present information and answer questions, the Finnish Meteorological Institute, the Natural Resources Institute Finland, and the City of Helsinki’s Harakka Nature Centre. Visitors will also have the opportunity to hear how noisy the underwater environment can be and learn about the well-preserved shipwrecks of the Baltic Sea.
Additionally, at the Quay, guests can visit the diving support vessel DSV Stella, the rescue cruiser Jenny Wihuri, and a Port of Helsinki presentation tent where experts explain how the Port addresses enviromental issues.

The Kansalaistori square: marine biodiversity showcased
Syke also participates in the Baltic Sea Festival activities taking place at Kansalaistori Square. These include the Treasures of the Sea and the Marine Habitat Restoration presentation tents. The Baltic Sea biodiversity is showcased, for example, through aquariums and photographs. A five-meter sediment sample offers a tangible glimpse into the sea’s history. At the venue, visitors can find out how marine habitat restoration supports a healthy Baltic Sea, and can, for example, send a letter to the Baltic Sea.

Guidelines for the visitors
The research vessel Aranda is not barrier-free. We welcome children onboard only with a supervising adult. For safety reasons, Aranda cannot accommodate daycare or other children’s groups. We do not recommend moving around the vessel with an infant. Visitors should be prepared to wait before boarding, as only a limited number of people can enter at a time.
The event in Kansalaistori Square is accessible for all. Activities are suitable for visitors of all ages.

Östersjöns tillstånd är fortfarande långt från målen – uppföljning som sträcker sig från kustvatten till öppet hav visar varför18.9.2026 08:30:00 EEST | Pressmeddelande
I augusti genomförde Finlands miljöcentral två uppföljningsresor i Östersjön: havsforskningsfartyget Aranda samlade in information från öppet hav och ms Hessu från Skärgårdshavet och kusten. Övergödning är fortfarande Östersjöns största miljöproblem. Enligt den statusbedömning av kustvattnen som publicerades i juni har endast sex procent av Finlands kustvatten god status. Färska mätningar och modelleringar ger en uppdaterad lägesbild av hur näringsbelastningen från land syns i kustvattnen och på öppet hav och varför havets tillstånd fortfarande är långt från målen.
The state of the Baltic Sea still far from the objectives – monitoring extending from coastal waters to the open sea explains why18.9.2026 08:30:00 EEST | Press release
In August, the Finnish Environment Institute carried out two monitoring cruises in the Baltic Sea: Research vessel Aranda collected data from the open sea and M/S Hessu from the Archipelago Sea and the coast. Eutrophication remains the biggest environmental problem in the Baltic Sea. According to the status assessment of coastal waters, published in June, only six per cent of Finnish coastal waters are in a good state. Recent measurements and modelling provide an updated situational picture of how nutrient pollution from land is reflected in coastal waters and the open sea, and why the state of the sea is still far from the objectives.
Itämeren tila on yhä kaukana tavoitteista – rannikkovesistä avomerelle ulottuva seuranta kertoo miksi18.9.2026 08:30:00 EEST | Tiedote
Suomen ympäristökeskus toteutti elokuussa Itämerellä kaksi seurantamatkaa: merentutkimusalus Aranda keräsi tietoa avomereltä ja ms Hessu Saaristomereltä ja rannikolta. Rehevöityminen on edelleen Itämeren suurin ympäristöongelma. Kesäkuussa julkaistun rannikkovesien tila-arvion mukaan vain kuusi prosenttia Suomen rannikkovesistä on hyvässä tilassa. Tuoreet mittaukset ja mallinnukset tarjoavat päivitetyn tilannekuvan siitä, miten maalta tuleva ravinnekuormitus näkyy rannikkovesissä ja avomerellä, ja miksi meren tila on edelleen kaukana tavoitteista.
Nostot medialle 21.–25.9.2026: Miksi Itämeren tila on yhä kaukana tavoitteista? Metsien ennallistamisessa etsitään tasapainoa metsäluonnon tilan parantamisen ja metsätalouden välillä17.9.2026 13:46:33 EEST | Tiedote

Metsien ennallistamisessa etsitään tasapainoa metsäluonnon tilan parantamisen ja metsätalouden välillä16.9.2026 14:55:34 EEST | Tiedote
Metsäluonnon ekologista tilaa on mahdollista parantaa yhteistyössä metsätalouden kanssa, painottavat Suomen ympäristökeskuksen (Syke) tutkijat. Arvokkaimpia kohteita voidaan suojella, kun taas muualla luonnon tilaa voidaan parantaa metsätalouden rinnalla ennallistamisasetuksen avulla.
