Scientists find microplastic pollution may alter Pacific Ocean color
Researchers published new findings in Communications Earth & Environment on November 6, 2026, suggesting decades of plastic waste are changing the hue of the Pacific Ocean near the Great Pacific Garbage Patch.
Tracking invisible plastic particles
Standard satellite infrared tools cannot detect microplastics because they are too small to scoop out at scale. Scientists realized that ocean color depends on dissolved or suspended materials like plankton and organic matter. This relationship allows researchers to look for changes in water color instead of searching for floating litter directly.
Study team and location
Shea Cheatham, Daniel Koestner and Børge Hamre conducted the investigation at an unspecified institution. The study focuses on the largest offshore plastic accumulation zone labeled the Great Pacific Garbage Patch. Decades of massive quantities of plastic ending up in oceans have created this specific environment for analysis.
