Marine debris is a globally recognised environmental issue of increasing concern. Marine ecosystems worldwide are affected by human-made refuse, much of which is plastic.

Marine debris comes from both land and sea-based sources and can travel immense distances. It can pose a navigation hazard, smother coral reefs, transport invasive species and negatively affect tourism. It also injures and kills wildlife, has the potential to transport chemical contaminants, and may pose a threat to human health.

CSIRO conducts world-leading, award-winning, research into the sources, distribution and fate of marine debris. This website outlines our research themes and projects in this area.
