Marine Litter

“The Litter is a Whole New Dimension”

AWI biologist Lars Gutow shares insights into his expeditions to the North Sea and Sargasso Sea, where he investigated how marine litter is spreading
Pathways of litter into the ocean

Plastic litter is present in large amounts in practically all the oceans. But where does all the litter come from, anyway? And how does it end up in the sea? This infographic shows the pathway of the litter into the world's oceans and the consequences that litter can have there
Using Expertise to Combat Marine Litter

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.

Good news: European sea bass absorb virtually no microplastic in their muscle tissue

In a new laboratory study, experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) investigated how many microplastic particles would be absorbed in the muscle tissue of young European sea bass after being given feed with extremely high microplastic particle content for a period of four months.

Scientific study

Microplastic drifting down with the snow

Over the past several years, microplastic particles have repeatedly been detected in seawater, drinking water, and even in animals. But these minute particles are also transported by the atmosphere and subsequently washed out of the air, especially by snow – this was demonstrated in a study conducted by experts at the Alfred Wegener Institute.

"We need to make fundamental changes"

The EU wants to ban single-use, disposable products such as drinking straws and ear swabs, the goal being to reduce the amount of plastic litter in our oceans. We discussed this initiative with two experts from the Alfred Wegener Institute, Helmholtz Centre for Polar and Marine Research (AWI) – Dr Melanie Bergmann and Dr Lars Gutow.
