Global Fishing Watch

Global Fishing Watch is a website launched in September 2016 by Google in partnership with Oceana and SkyTruth "to provide the world’s first global view of commercial fishing activities." At any moment, 200,000 vessels are publicizing their locations via the Automatic Identification System (AIS).
Global Fishing Watch enables users with Internet access to monitor fishing activity globally, and to view "individual vessel tracks, exclusive economic zones, marine protected areas, and other features." It is hoped that the initiative can help to reduce "global overfishing, illegal fishing and habitat destruction."
The technology was made publicly available at the 2016 US State Department's "Our Oceans Conference" in Washington DC. The project was partly financed by the Leonardo DiCaprio Foundation.
