Microplastic Pollution Map

To study the medium to long-term effects of microplastics on humans and animals, OEOO has been involved for years in setting up a database on the levels of microplastic pollution in the oceans.

One Earth – One Ocean e.V.’s Microplastic Pollution Map is the first interactive world map to document the nature and extent of marine pollution through microplastics.

In order to obtain up-to-date raw data on the pollution levels with microplastic in the waters, water samples of the North Sea, the Atlantic and the Mediterranean are currently being collected regularly. OEOO has been cooperating with the shipping line OPDR from Hamburg since 2013, whose ships sail on fixed routes between Northern Europe and Africa. These samples are analyzed for their chemical composition by OEOO in their own laboratory using a FTIR spectrometer. The results flow into the OEOO database and are available to the public on this interactive world map. The association is looking for cooperation partners in order to collect data from water samples wherever possible.

Applications

The Microplastic Pollution Map contains several windows. The chart shows the sample positions for the microplastic examinations. These can be sorted according to different criteria: it is possible to search for sea areas, for more detailed sampling locations, for the years of sampling or also for plastic types. By clicking on the subsegments or by ticking the sampling years, the selection is made.

The corresponding samples are displayed in the nautical chart and the log sheet shows the individual samples and the plastics identified therein.

By pressing the CTRL key, the mouse can be used to make multiple selections within a category (e.g., year of sampling, location of sample, type of plastic).

In the nautical chart, individual sampling locations can also be marked. The corresponding log extracts are then displayed.
