The Baltic Sea is highly eutrophic, with anoxic seabeds and large algal blooms. But if the countries surrounding the sea had not reduced nutrient discharges, the situation would have been much worse.

Samples of bladderwrack have been sent into space as a first step towards understanding its mysterious reproduction. "An absolutely breathtaking experience," says Professor Emeritus Lena Kautsky.

Large predatory fish have become harder to find in the coastal bays of the Baltic Sea, now dominated by sticklebacks. Scientists are still looking for explanations and for if this could have unforeseen climate impacts.

In a new research school, PhD students from diverse disciplines get a unique opportunity to learn how transdisciplinary approaches and research communication can lead to sustainable management of coastal environments.

Is there a difference between healthy and degraded coastal bays in terms of greenhouse gas emissions and uptake? Come with us to Sandviken Bay, where the first of several days of a new sampling campaign took place.

Assessments of combined impacts in marine spatial planning and fisheries management need to improve. A new report presents ways to develop these.

Why does primary production of plastics need to be reduced and what's at stake at the global plastics negotiations in South Korea?

A new policy brief states that more no-take zones should be introduced in Sweden to protect marine ecosystems. But areas need to be extensive and designed correctly.

Reducing nitrogen losses is important to meet environmental targets and bring the nitrogen cycle within sustainable planetary boundaries. More targeted measures are needed in areas where risk of leaching is high.
