Free and open data to inspire next wave of ocean solutions

Global Fishing Watch establishes new portal to make application programming interfaces available to public Inequitable access to data and technology in support of ocean stewardship often leads to lost opportunities in decision-making and innovation—especially in under-resourced countries.  The international community continues to fall short in its efforts to conserve and sustainably use the ocean and […]

Transshipment Data and Report

Today we published our initial research on transshipment at sea. Transshipment at sea is where a fishing vessel offloads its catch to a refrigerated cargo vessel (or “reefer”) far from port. You can download a copy of our report via this link. The image above was created by our data scientist Nate Miller, who has spent […]

Machine learning and satellite data provide the first global view of transshipment activity

This week marks the publication of the first-ever global assessment of transshipment in a scientific journal. Researchers at Global Fishing Watch and SkyTruth, in the journal Frontiers of Marine Science, published “Identifying Global Patterns of Transshipment Behavior.” What is transshipment? Why does it matter? What have we learned and what remains unknown? Read on to […]

86,490 Points on a Map: All Potential Transshipments

5 years, over 86,000 potential transshipments In early 2017, we released an original report based on analysis of our data that revealed remarkable new insights about what goes on between fishing vessels at sea. The machine learning platform we developed found that over the past five years, there were more than 86,000 potential cases in which fishing […]
