The State of the Baltic Sea in 2013

13.05.2014

Annual assessment of the physical and chemical data finalized: Even the hurricane „Xaver“ did not end the stagnation period effecting the bottom water of the Baltic Proper.

Only a bit of a good news first: During 2013 specific meteorological conditions led to four salt water inflows bringing oxygen-rich saltwater from the North Sea across the Darss Sill into the Baltic.

The consequences in form of an increase in the salt and oxygen content of the bottom water could be detected in the western Baltic and as far as to the Bornholm Basin.

However, these events did not improve the conditions in the central part of the Baltic Sea: In the bottom water of Gotland Deep the highest concentrations of hydrogen sulfide since the beginning of the stagnation period in 2005 were measured. Simultaneously, the salinity of the deep water layers in this region of the Baltic Sea decreased.

The results of the concentrations of the nutrients nitrate and phosphate, too, cannot be classified as “good news”: the measurements in the central Baltic Sea did not confirm the decrease in nutrient concentrations observed in coastal waters.

This shows that further efforts are needed to reduce nutrient inputs into the Baltic Sea.Since several decades, the Leibniz Institute for Baltic Sea Research Warnemuende carries out regular assessments on the state of the Baltic Sea.

Each year, five cruises are conducted to measure hydrographic and chemical data on approximately 60 stations between Kiel Bight and Northern Gotland Basin. The results are summarized and published in annual assessments of the hydrographic and chemical conditions.

At the same time, these data are provided to the Helsinki Commission, which uses them for further thematic and holistic assessments of the Baltic. Thus, they serve the compliance of the demands of the EU Marine Strategy Framework Directive and the implementation of HELCOM’s the Baltic Sea Action Plan.

The IOW is a member of the Leibniz Association to which 89 research institutes and scientific infrastructure facilities for research currently belong. The focus of the Leibniz Institutes ranges from Natural, Engineering and Environmental Science to Economic, Social, and Space Sciences and to the humanities. The institutes are jointly financed at the state and national levels. The Leibniz Institutes employ a total of 17.200 people, of whom 8.200 are scientists, of which 3.300 are junior scientists. The total budget of the Institutes is more than 1.5 billion Euros. Third-party funds amount to approximately € 330 million per year.

Im Focus: OU astrophysicist and collaborators find supermassive black holes in quasar nearest Earth

A University of Oklahoma astrophysicist and his Chinese collaborator have found two supermassive black holes in Markarian 231, the nearest quasar to Earth, using observations from NASA's Hubble Space Telescope.

The discovery of two supermassive black holes--one larger one and a second, smaller one--are evidence of a binary black hole and suggests that supermassive...

Im Focus: What would a tsunami in the Mediterranean look like?

A team of European researchers have developed a model to simulate the impact of tsunamis generated by earthquakes and applied it to the Eastern Mediterranean. The results show how tsunami waves could hit and inundate coastal areas in southern Italy and Greece. The study is published today (27 August) in Ocean Science, an open access journal of the European Geosciences Union (EGU).

Though not as frequent as in the Pacific and Indian oceans, tsunamis also occur in the Mediterranean, mainly due to earthquakes generated when the African...

Im Focus: Self-healing landscape: landslides after earthquake

In mountainous regions earthquakes often cause strong landslides, which can be exacerbated by heavy rain. However, after an initial increase, the frequency of these mass wasting events, often enormous and dangerous, declines, in fact independently of meteorological events and aftershocks.

These new findings are presented by a German-Franco-Japanese team of geoscientists in the current issue of the journal Geology, under the lead of the GFZ...

Im Focus: FIC Proteins Send Bacteria Into Hibernation

Bacteria do not cease to amaze us with their survival strategies. A research team from the University of Basel's Biozentrum has now discovered how bacteria enter a sleep mode using a so-called FIC toxin. In the current issue of “Cell Reports”, the scientists describe the mechanism of action and also explain why their discovery provides new insights into the evolution of pathogens.

For many poisons there are antidotes which neutralize their toxic effect. Toxin-antitoxin systems in bacteria work in a similar manner: As long as a cell...

Im Focus: Fraunhofer IPA develops prototype of intelligent care cart

It comes when called, bringing care utensils with it and recording how they are used: Fraunhofer IPA is developing an intelligent care cart that provides care staff with physical and informational support in their day-to-day work. The scientists at Fraunhofer IPA have now completed a first prototype. In doing so, they are continuing in their efforts to improve working conditions in the care sector and are developing solutions designed to address the challenges of demographic change.

Technical assistance systems can improve the difficult working conditions in residential nursing homes and hospitals by helping the staff in their work and...
