Electronics, batteries and icy conditions

On the frozen sea outside the facility of UMF, french scientists are testing instruments intended for autonomous water measurements in cold conditions.

EcoChange digs deep into disrupted food web

Climate change will make the marine food web less efficient, and toxic substances will increase in fish and other organisms. This became clear during the first phase of EcoChange, and now it´s time to dig deeper into these questions. “A large part of our work concerns what the effects of the loss in...

The mesocosms have been launched

During fall there has been a febrile activity in the workshop at Umeå Marine Sciences Center. Within the international project AQUACOSM, UMF will develop a type of mesocosm that can withstand harsh arctic conditions. Now the first prototypes are in the water.

Uptake of mercury in focus

Erik Björn, researcher at the department of Chemistry at Umeå University, has together with his research group performed several conspicuous studies on methylmercury in aquatic environments, and how climate change will affect the amounts of this toxin in the ecosystem. However, an important but stil...

EcoChange participates in worldwide contaminant monitoring

Persistent organic pollutants, POPs, can be harmful to living organisms even in low concentrations. They are stable and persistent, and can be found far away from their sources. Until recently the systematic monitoring of these substances has been done mainly in air. Focus is now gradually moving to...

Mercury in the UMF mesocosms

The twelve mesocosms at Umeå Marine Sciences Centre are running at full speed. During five weeks experiments are performed by a research team led by Erik Björn and Agneta Andersson, Umeå University. They are hoping to find out how humic substances influence the accumulation of methyl mercury in the ...

Phytoplankton in the mix

This week, Russell Arnott from the University of Bath, is visiting Umeå Marine Sciences Centre. In his research, he is using UMF's mesocosms to determine to what degree the size and shape of a particular phytoplankton species dictates how it interacts with different levels of turbulence.

Pathogenic bacteria train their defence in lakes and oceans

Peter Mathisen at Umeå University has found links between the aquatic environment and the spreading of diseases such as tularaemia. The results indicate that aquatic environments act as “gyms” for bacteria, where the presence of predators train their defence against being killed and eaten up. The re...
