🌊 75 percent of industrial fishing vessels are not publicly tracked.
These blind spots make it harder to monitor activity at sea, detect suspicious behavior and combat illegal fishing.
Public vessel tracking can help strengthen transparency and ocean governance worldwide.

🌊 Deep-sea mining is moving closer to reality, but much of the activity linked to it remains hidden from view.
Deep Sea Mining Watch, developed by @UCSBenioffOcean and powered by Global Fishing Watch technology, combines satellite data, mapping tools and open data to help illuminate activity linked to deep-sea mining exploration in some of the most remote parts of our ocean.
