Marine biologists and environmental researchers from the University of Ruhuna have expanded an oceanographic field study assessing microplastic density along the Galle and Unawatuna coastal reef ecosystems.

Utilizing high-precision particulate sampling filtration and infrared spectroscopy, research teams are mapping polymer distributions in coastal waters and marine fauna to determine ecological contamination risks. The research initiative, funded through regional marine conservation grants, aims to deliver actionable scientific data to guide municipal marine litter regulations and protect sensitive southern aquatic biodiversity.
