Microplastics Alert

Scientific American 2023
J Lauren

Summary

Researchers discovered that high concentrations of microplastics at the ocean surface dampen wave height in ways detectable by satellite altimeters, enabling remote sensing to map microplastic distribution at global scale. This breakthrough method could dramatically improve monitoring of ocean plastic pollution and guide cleanup and policy efforts without requiring costly ship-based sampling campaigns.

Study Type Environmental

Researchers figured out how the flow of microplastics flattens ocean waves, letting satellites paint a clearer picture for future policy and cleanup efforts
