Navigating the Challenges of Marine Light Pollution

Advancing Knowledge, Awareness, and Solutions for a Brighter Marine Future

Light Pollution Threatens Coastal Marine Systems

Light pollution extends beyond our cities, casting a disruptive glow over coastal waters and threatening marine ecosystems. At GOALANN, we’re shedding light on how artificial illumination affects ocean life, from the smallest plankton to the great whales, disrupting natural behaviours and endangering vital habitats.

22% of the world’s coastlines are impacted by light pollution nightly.

1.6 million kilometres squared of the worlds exclusive economic zones are exposed to biologically important light pollution to a depth of at least 10m.

Light pollution at sea remains almost completely unregulated by national and international policy.

Our Path to Healthier Oceans

GOALANN is an international network of the world’s leading experts in marine light pollution.  Our mission is to conserve the oceans by improving knowledge and awareness of marine light pollution, its ecological and societal impacts, and management options.

The initiative unifies research groups from around the world to provide a central resource of marine light pollution expertise, projects and tools for policy makers, environmental managers, maritime industries, the media and the public.
