Trialling Pumps to Oxygenate the Baltic

18.12.2008
Can large-scale pumps inject oxygen and life into the lifeless seabed of the Baltic?

This is what a pilot study, conducted by researchers at the University of Gothenburg, will try to establish, with the help of SEK 20 million from the Swedish National Environmental Protection Agency (Naturvårdsverket) and the Swedish Research Council Formas.

The Baltic Sea is actually characterised by a high phosphate content and by a considerable algal bloom during the summer. But it has not always been like that.

During the 1990s the phosphorus content in the Baltic fell by a third, a reduction which coincided with a marked thermocline which increased the oxygen content down to a depth of 120 m. These circumstances show that it should be possible to bring about a rapid reduction in the eutrophication symptoms in the Baltic proper, by adding water that is rich in oxygen in an artificial way and mixing the bodies of water intensively.

Investing 20 million
The question is whether it is possible to maintain the Baltic in this oxygen rich state, by continuously adding oxygen rich water to the deep water. This is what will now be investigated in a pilot project conducted by researchers from the University of Gothenburg. The project, called Box, is receiving support amounting to SEK 20 million from Formas and the Swedish National Environmental Protection Agency (Naturvårdsverket).

"We are going to investigate how you succeed in retaining the phosphorus in the bottom sediment under different external circumstances, with and without artificial oxygenation, in two coastal basins. Among other things we will be using the prototype of a wind-driven pump, but we will also investigate how a full-scale pump system in the Baltic proper might be designed," says project director Anders Stigebrandt, Professor at the Department of Earth Sciences at the University of Gothenburg.

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...

Im Focus: Glacier bacteria’s contribution to carbon cycling

Glaciers might seem rather inhospitable environments. However, they are home to a diverse and vibrant microbial community. It’s becoming increasingly clear that they play a bigger role in the carbon cycle than previously thought.

A new study, now published in the journal Nature Geoscience, shows how microbial communities in melting glaciers contribute to the Earth’s carbon cycle, a...
