‘Scratching’ more than the ocean’s surface to map global microplastic movement

Researchers have mapped global microplastic distribution patterns by size and polymer type, revealing that microplastics are deeply embedded in the ocean's structure. The study found that smaller microplastics spread more evenly and penetrate deeper, while larger ones concentrate near the surface, affecting key biogeochemical processes.
