The Amazon and the sea: Expedition investigates matter fluxes and food webs in the world’s largest river plume
With the help of highly resolved realistic model simulations physicists at the IOW have succeeded in depicting the so-called submesoscale dynamics in the Eastern Gotland Basin – the deepest of the large basins of the central Baltic Sea. Thus, the researchers gained the opportunity to investigate these highly dynamic phenomena, which – although being known for decades through satellite images – are up to now only scarcely studied and poorly understood because of their small size and short-lived nature.
Submesoscale dynamics in the heart of the Baltic Sea: High-resolution model reveals new insights

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.
