Ocean Monitoring and Illegal Fishing

The video discusses the issue of illegal and unreported seafood catch, emphasizing the difficulty of managing what cannot be seen. It introduces Global Fishing Watch's use of GPS data to monitor industrial fishing fleets and highlights the challenge of 'dark vessels' that do not share their GPS data. To address this, satellite-based radar and optical imagery are used to reveal hidden fishing activities, such as those in North Korean waters. The techniques developed can be applied globally to combat illegal fishing and improve ocean management for the common good.
