Umeå Marine Sciences Centre (UMF) is a research centre at Umeå University, organised under the Faculty of Science and Technology and situated in Norrbyn, 40 kilometres south of Umeå. UMF supports marine research and education, and performs environmental analysis on commission of swedish environmental monitoring. We also provide information about research and environmental status, with a particular focus on the Gulf of Bothnia.

Global warming is expected to increase runoff and input of organic matter to aquatic ecosystems in large regions of the Northern hemisphere including the Baltic Sea. Research performed in Sweden is now indicating a sevenfold increase in poisonous methylmercury in zooplankton as a consequence. This increase is due to an altered structure of the aquatic food web. The study has been published in the journal Science Advances.
When the discharge of river water into the sea increases, for example as an effect of climate change, the ratio between phytoplankton and bacteria production will change. Phytoplankton growth is disfavoured by both the organic carbon in the river water and the changes in depth of the upper layer of water. This is shown in a new study performed within the research programme EcoChange.

EcoChange researcher Jenny Ask has received funding from Formas for a project about ice-cover regimes in northern aquatic ecosystems. The project will focus on how future changes in ice-cover will impact aquatic carbon metabolism, algal biomass build-up and water-atmosphere gas exchange.
EcoChange researcher Joanna Paczkowska has focused on the base of the food web, to figure out what climate change will do to the ecosystem along a north-south gradient in the Baltic Sea. She proves that carbon compounds originating from land have a great impact on the structure and function of the i...
Every year news media report on troublesome blooms of cyanobacteria. The problems are related to the eutrophication of the Baltic Sea, and with the climate change the blooms are predicted to worsen. Cyanobacteria seem to be extremely capable of adapting to changes in the environment. However, it is ...
Algae are responsible for a large part of the production of organic matter in the sea and their importance for the northern Baltic Sea has so far been underestimated, according to a study conducted by the research programme EcoChange at Umeå University.
