Researchers Discover Major Ecological Shift in the Gulf of Bothnia

For decades, scientists have regarded phosphorus as the main nutrient limiting biological production in the Gulf of Bothnia. Now, a new study led by researchers at Umea University shows that a fundamental change is underway. The Bothnian Sea has shifted to nitrogen limitation, while the Bothnian Bay is rapidly moving in the same direction.
