Professor Daniel Conley has been awarded USD 150 000 from the Pew Charitable Trusts in the USA. The money will go to his research on oxygen depletion in the Baltic Sea. For a number of years, Professor Conley's research has focused on how to tackle the problem of dead seabeds. Daniel Conley is a biogeochemist and conducts research on the flow of nutrients on land and in the sea. He works at the Department of Earth and Ecosystem Sciences at Lund University.
The reason for the oxygen depletion in the Baltic Sea is the large input of nutrients from the land to the sea, primarily from agriculture and fossil fuels. The nutrients cause eutrophication in the sea; algae grow rapidly when there is a greater supply of nutrients, but when the algae die and rot on the seabed, large amounts of oxygen are used in the rotting process, which leads to a lack of oxygen. When there is little oxygen, animals and plants cannot live there and problems of dead seabeds arise. The dead seabeds in the Baltic are the world's most extensive example of oxygen depletion resulting from human emissions.
Now Daniel Conley will carry out a three-year scientific evaluation of a number of methods that aim to remedy the dead seabeds in the Baltic Sea. Daniel Conley will investigate the effectiveness and cost of the methods, as well as the impact on animals and plants. In addition, he will compare new technical solutions with more traditional methods.
In recent years a number of new technical solutions to the problem of oxygen depletion in the sea have been proposed and tested, in addition to the more traditional methods that are first and foremost about trying to reduce the transfer of nutrients from the land. One example of a new solution is to actively introduce oxygen gas into the water at depth in order to reduce oxygen depletion on the seabeds.For more information, please contact:

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.
As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...
Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.
Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...
For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.
While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...
An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.
The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...
A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.
Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
