A “model message” to decision-makers: Continued nutrient reduction measures will reduce “dead zones” in the end

A team of climate modellers used an extensive multi-model ensemble to investigate the effects of climate change on the “dead zones” of the Baltic Sea. They showed that a reduction in the size of these areas can be achieved by 2100 if nutrient discharges are consistently reduced – despite climate change. For individual Baltic Sea regions, they determined an earlier visibility of changes than in others. They recommend intensifying observations there.

Microplastic pollution of the Baltic Sea: New insights into behaviour, sinks and reduction measures

In order to assess the impact of microplastics on the oceans, it is necessary to know their quantity and their behaviour in the sea. So far, this knowledge is still incomplete because of a high analytical effort and high costs. For the Baltic Sea, comprehensive calculations of microplastics emissions are now available for urban pathways. Together with 3D-model simulations they provide new insights into transport, behaviour and deposition of microplastics in the marine environment.

Home run for the RV Maria S. Merian: Research vessel sets off towards the Baltic Sea ice for the “Deep Baltic” mission

From February 25 to March 23, 2021, a team of physicists and geologists from Warnemünde, Kiel and Szczecin will be underway in the northern Baltic Sea to investigate the dynamics of winterly deep water circulation. Besides recording the current hydrodynamic conditions near and under the sea ice of the Gulf of Bothnia, the program includes sedimentological and geophysical studies to investigate sediment erosion and deposition characteristics induced by deep-water movement. A further aim is to reconstruct the history of deep water circulation in the northern Baltic Sea during Holocene climate variations recorded in older sediments.

In search of the “Golden Spike”: On the role of microplastics in defining the Anthropocene

In a recently published discussion paper, Juliana Ivar do Sul and Matthias Labrenz, environmental scientists at the IOW, focus on the topic of microplastics from a geological perspective. They discuss whether the omnipresent plastic particles could be used to identify the beginning of a new, not-yet formalised geological epoch, the Anthropocene, in geo-archives such as sediment cores. Moreover, microplastics could be used at a suitable location to establish the so called Golden Spike, which, by definition, is used in geology to document the beginning of an epoch, period or era.

First-time detection of glyphosate in the sea: IOW develops new method and successfully applies it to Baltic Sea samples

Glyphosate is one of the world’s most widely used weed killers. The disputed herbicide, which is suspected to be carcinogenic among other things, gets transported from the on-land application areas into rivers, which wash it into the sea. So far it was unclear, however, how much can be found in marine environments, because glyphosate and its metabolite aminomethylphosphonic acid could not be measured in saltwater due to methodological reasons. Marisa Wirth from the IOW has now developed a new method, with which both substances can reliably be measured in seawater and for the first time was able to detect glyphosate and AMPA in the Baltic Sea.

IOW operations during corona

Due to the corona pandemic, the IOW has reorganised its operations so that the majority of its employees works from home. Until further notice, the known distance and hygiene rules apply.This includes the wearing of a mouth-nose cover everywhere in the IOW as soon as more than one person is present.

Guests and students may only be admitted with a special permit.
