Gone with the wind: A new project focusses on atmospheric input of phosphorus into the Baltic Sea

04.09.2015

In August, the Leibniz Institute for Baltic Sea Research Warnemünde (IOW) received the funding approval from the German Federal Environmental Agency (UBA) referring to a two-year pilot study on the atmospheric input of phosphorus in the Southern Baltic Sea. The project started with the beginning of September.

Over-fertilization and its consequences still are the major environmental issues of the Baltic Sea. To reduce the discharge of nutrients, therefore, is of utmost importance in all Baltic Sea riparian countries. A good environmental status as described in the Marine Strategy Framework Directive to be accomplished by the year 2020 will not be in reach without measures to reduce the nutrient load.

Great progress was already made in reducing the riverine loads. But apart from this, input via so called „diffuse sources“ – a category which also comprises the atmospheric input - still are difficult to handle. To date, the amount entering the Baltic via this pathway is estimated to sum up to 2.100 tons, representing 5.5% of the total 38.300 tons of phosphorous discharged into the Baltic. It is on this basis, that reduction goals for phosphorus were calculated.

However, there were studies resulting in values of 9.100 tons of annual atmospheric input. In case, these figures turn out to be more realistic than the former estimations, the phosphorus input had to be reduced by a much higher rate than currently debated in order to reach a good environmental status.

Within the new project the measuring campaigns will cover all four seasons, both, on- and off-shore. A further goal will be to determine the share of non-natural sources, as only those are considered to be subject to reduction measures.

In contrast to the atmospheric sources of nitrogen which due to its negative effects on the human health and the ecosystems is constantly under observation, the anthropogenic sources of phosphorus are only scarcely known. Scientists assume that it is mainly discharged in form of particles, like pollen, dust escaping from fertilizer production plants or ignition processes. Wind erosion on open arable land or forest clearance areas will surely contribute to a transport of phosphorous-containing material into the sea.

Besides improving the state of knowledge, the new project will also aim at the development of recommendations referring to the description of reduction measures within the frame of a new environmental goal indicator „Atmospheric Phosphorus Deposition“.

The IOW is a member of the Leibniz Association with currently 89 research institutes and scientific infrastructure facilities. The focus of the Leibniz Institutes ranges from natural, engineering and environmental sciences to economic, social and space sciences as well as to the humanities. The institutes are jointly financed at the state and national levels. The Leibniz Institutes employ a total of 18.100 people, of whom 9.200 are scientists. The total budget of the institutes is 1.64 billion Euros. www.leibniz-association.eu

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
