Microplastics in the Sea

Alarming news about the growing littering of the seas and the omnipresence of microplastics trigger the public concern. Marine scientists are working with special emphasis to answer open questions related to this highly topical environmental issue. At the IOW, we investigate

• whether microplastics might serve as an ideal transportation vehicle for pathogenic germs

• how methods to determine microplastics, which today are still very time-consuming, can be improved

• which are the sources and pathways of microplastics into the sea.

Baltic Sea ‘dead zone’ development, 1969 – 2015: IOW publishes detailed map material based on long-term data

To visualise the spatial and temporal distribution and dynamics of these areas, IOW now has published in the 100th issue of its journal “Marine Science Reports” a unique collection of over 250 maps covering data of more than four decades.
