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

Researchers at the University of New Hampshire have captured a difficult-to-view singular event involving "magnetic reconnection"--the process by which sparse particles and energy around Earth collide producing a quick but mighty explosion--in the Earth's magnetotail, the magnetic environment that trails behind the planet.
Magnetic reconnection has remained a bit of a mystery to scientists. They know it exists and have documented the effects that the energy explosions can...
