Global Fishing Watch and The Pew Charitable Trusts present this public portal to improve transparency and management of transshipment at sea. Satellite technology, machine learning, and up-to-date vessel authorization databases give users information on carrier vessels’ activities, allowing them to analyze vessel tracks and see which ports are most frequented.
