Time traveling with biomarkers: Baltic Sea sediment archives reveal frequency of “blue-green algae” since 1860

Researchers from Warnemünde and La Jolla, California, have succeeded for the first time in reconstructing the history of blue-green algae blooms in the central Baltic Sea over the last 160 years by using biomarkers and a well-dated sediment core. This way, they extended the period, for which information on the frequency of blooms was previously available, well into the past. In the international journal “Biogeosciences” they discuss possible causes for the fluctuations they detected.

To end the eutrophication of the Baltic Sea: Do the measures show effects?

Between 1995 and 2014, river discharges of the two main drivers of eutrophication, nitrogen and phosphorus, were significantly reduced in the western Baltic Sea. But are these measures also having an effect in the open Baltic Sea? The marine chemists of the IOW have not yet found any clearly discernible changes there. In a recently published study, they report on a method they used to track the fate of nutrients from river mouths into the Baltic Sea.

Evaluation: Leibniz Association praises the IOW’s performance and recommends expansion of research with additional funds

The Leibniz Association senate concluded the regular evaluation of the IOW with a very positive assessment and recommends that the federal and state governments continue their joint funding of the institute. It states that the IOW has successfully advanced its scientific profile, focusing both on the unique ecosystem of the Baltic Sea and on more global issues such as climate change impacts, marine litter and biodiversity. The senate strongly supports the plan to expand the institute's technical and methodological spectrum through an additional 2 million euros per year in order to conduct more research on shallow coastal waters.

Our “top athletes” on the seafloor: Hediste diversicolor, Arctica islandica, Echinocardium cordatum, Amphiura filiformis

A comparative study in four sea regions (German Baltic Sea, German North Sea, Belgian part of the North Sea and Eastern Channel) identified the organisms behind these Latin names as the most important actors in wide areas of the North Sea and the Baltic Sea in terms of bioturbation. They ensure that the bottom is supplied with oxygen, which triggers a chain of other vital processes. In different environments, only the ranking within this group changes. An international team led by the Warnemünde biologists Mayya Gogina and Michael Zettler now published the results. Using maps of the bioturbation potential, they defined areas of high ecosystem service particularly worthy of protection.

Upwards with the “bubble shuttle”: How sea floor microbes get involved with methane reduction in the water column

For the first time, an IOW research team has been able to determine the efficiency with which methane-oxidising bacteria from the seafloor can travel with gas bubbles from submarine methane seeps into the open water column and influence biogeochemical processes there.

IOW operations during corona

IOW has adapted its operations to the current Corona situation as follows:

Many of our staff still work from home. Therefore, the best way to reach us is by telephone or e-mail.

In particular, we ask service providers or suppliers to contact their respective client at the IOW by either phone or e-mail. We ask for your patience in case of any delays in processing.

Access to the building for guests and students is only possible with explicit permission and by registration of contact details. In all public spaces of the IOW, the established distance and hygiene rules continue to apply, such as the wearing of protective medical masks.

The IOW maintains the right to reintroduce mandatory testing of visitors or to prohibit access altogether if the situation deteriorates. The institute management will announce this here.

Still, please feel free to contact us any time:
