Microplastics: A truly colourful pile
Scientists define microplastics as collection of small and large fragments, pellets, fibers, sheets, and other objects smaller than five millimeters. They come in different shapes and colors - a diversity that it actually breathtaking, as this gallery shows.

Arctic ice algae heavily contaminated with microplastics
The alga Melosira arctica, which grows under Arctic sea ice, contains ten times as many microplastic particles as the surrounding seawater. This concentration at the base of the food web poses a threat to creatures that feed on the algae at the sea surface. Clumps of dead algae also transport the plastic with its pollutants particularly quickly into the deep sea - and can thus explain the high microplastic concentrations in the sediment there. Researchers led by the Alfred Wegener Institute have now reported this in the journal Environmental Science and Technology.
Debris in the Arctic
Plastic debris in the Arctic comes from all around the world – including Germany
“Citizen Science” gives interested citizens the chance to actively engage in scientific research. A citizen-science project conducted by AWI in the Arctic now shows just how successful this can be. In the course of five years, citizens who went on sailing cruises to the Arctic surveyed and collected plastic debris that had washed up on the shores of Svalbard. This has now been analysed by the AWI.
Heavy threatening of biodiversity by microplastic
As part of an investigation of the Western Pacific Kuril-Kamchatka Trench, Senckenberg researchers, with the support of AWI scientists and researchers from Goethe University Frankfurt, have proved high levels of microplastic pollution, which is greater than previously assumed. While evaluating the sediment samples, the research team found that each of the 13 samples taken from a depth of up to 9450 meters contained between 215 and 1596 tiny microplastic particles per kilogram.
