A global atlas of artificial light at night under the sea

The impacts of artificial light at night (ALAN) on marine ecosystems have emerged as a focus for ecological pollution research in recent years, yet the global prevalence ALAN underwater is unknown. We derived atlas throughout water column that will accelerate our understanding its sources and environmental impacts. At depth 1 m, 1.9 million km2 world’s coastal seas are exposed to biologically important ALAN, which equates around 3.1% exclusive economic zones. This area decreases 1.6 (2.7%) 10 840,000 (1.4%) 20 m. most heavily regions those experience intensive offshore development addition urbanization. highlights change issue not land but also widespread habitats irradiances elicit biological responses organisms.
