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: Scientists channel graphene to understand filtration and ion transport into cells

Tiny pores at a cell's entryway act as miniature bouncers, letting in some electrically charged atoms--ions--but blocking others. Operating as exquisitely sensitive filters, these "ion channels" play a critical role in biological functions such as muscle contraction and the firing of brain cells.

To rapidly transport the right ions through the cell membrane, the tiny channels rely on a complex interplay between the ions and surrounding molecules,...

Im Focus: Towards data storage at the single molecule level

The miniaturization of the current technology of storage media is hindered by fundamental limits of quantum mechanics. A new approach consists in using so-called spin-crossover molecules as the smallest possible storage unit. Similar to normal hard drives, these special molecules can save information via their magnetic state. A research team from Kiel University has now managed to successfully place a new class of spin-crossover molecules onto a surface and to improve the molecule’s storage capacity. The storage density of conventional hard drives could therefore theoretically be increased by more than one hundred fold. The study has been published in the scientific journal Nano Letters.

Over the past few years, the building blocks of storage media have gotten ever smaller. But further miniaturization of the current technology is hindered by...
