“Global Fishing Watch was co-founded by Google, marine conservation body Oceana, and environmental group SkyTruth. The latter studies satellite images to spot environmental damage.

To try to better monitor and quantify the problem of overfishing, Global Fishing Watch is now using increasingly sophisticated AI software, and satellite imagery, to globally map the movements of more than 65,000 commercial fishing vessels, both those with – and without – AIS.

The AI analyses millions of gigabytes of satellite imagery to detect vessels and offshore infrastructure. It then looks at publicly accessible data from ships’ AIS signals, and combines this with radar and optical imagery to identify vessels that fail to broadcast their positions.”
