CO2 removal from atmosphere is crucial for climate protection – Annual CDRmare conference focuses on ocean-based methods

Worldwide, research is warning that it will soon be impossible to curb man-made climate change to a point where the internationally agreed climate targets can be met. Even a drastic reduction in carbon dioxide (CO2) emissions implemented immediately is no longer sufficient, but will have to be supplemented by additional removal of CO2 from the atmosphere. This is the background for the 2nd annual conference of the research mission CDRmare of the German Marine Research Alliance (DAM), which starts today in Stralsund.

Smoke on the Water – Scientists from Rostock and Prague trace ship emissions over and in the Baltic Sea

Ship exhausts generated over the heavily trafficked Baltic Sea affect the marine environment and human health. Within the “PlumeBaSe”* project, researchers from the IOW, the University of Rostock and the Charles University in Prague are now investigating how the emitted pollutants spread above and in the sea, how they change in the air and in the water, and what can be inferred from this for improved exhaust gas cleaning.

Microplastic pollution in the Northeast Atlantic: First long-term record from deep water layers of the open ocean

Scientists from the IOW for the first time analysed a long-term sample series on microplastic pollution in the Northeast Atlantic from 2000 m water depth with respect to number, size, mass, material and possible origin of the particles. Samples were collected between 2003 – 2015 in the Madeira Basin by a sediment trap. Plastic type and particle amount varied widely, but accounted for up to 8% of total particle flux. The most common plastic materials were polyethylene and PVC.

TRR 420: DFG funds new Collaborative Research Centre

On May 28, 2025, the German Research Foundation (DFG) approved funding for the Collaborative Research Centre / Transregio (TRR) 420 “CONCENTRATE”. Headed by the universities of Greifswald and Bremen, the researchers in the consortium are investigating sugar polymers from marine algae and how they help to protect the climate. The IOW is involved with a partial project on the role of marine fungi in the transformation of these sugar polymers.
