Scientists find highest ever level of microplastics on seafloor

An international research project has revealed the highest levels of microplastic ever recorded on the seafloor, with up to 1.9 million pieces in a thin layer covering just 1 square meter. The hotspots appear to be the deep-sea equivalents of the so-called ‘garbage patches’ formed by currents on the ocean surface.

Microplastics found in Antarctic ice cores

A team of researchers from the University of Tasmania has found evidence of microplastics in ice cores collected off the coast of Antarctica. They also note that prior studies have shown that microplastics in ice can lead to melting due to heat absorption.

What began as one man on an cleanup mission has grown into one of the US’s most impactful river initiatives.

Litter problem at England’s protected coasts

Beaches in or near England’s Marine Protected Areas (MPAs) have the same levels of litter as those in unprotected areas, new research shows. The study used 25 years of beach cleanup data.
