Illuminating global fishing activity with satellite AIS

This article was produced and first published by our data partner, Spire Global. Transparency in a whole new light In February this year, a Vietnamese ship entered Indonesian waters, likely fished illegally, and then returned to port without consequence. By March, it was back at sea. There were no signs to indicate that the vessel […]

Whaling off the map

Are whaling vessels that operate without using aids to avoid vessel collision putting the safety of biodiversity and people at risk?   This week the International Whaling Commission (IWC) has convened in Slovenia. The gathering marks the 30th anniversary of the commission’s moratorium on commercial whaling.

Datasets and Code: Vessel Identity

Datasets and Code: Vessel Identity Transparency plays a central role in promoting the sustainability of marine resources and advancing ocean governance. Information that allows us to better understand vessel identity is a fundamental part of transparency. But such information is often fragmented, incomplete or inconsistent across multiple sources, and sometimes it is not publicly available […]

Ask the Expert: Tim Hochberg, Senior machine learning engineer

Ask the Expert Tim Hochberg Senior machine learning engineer How do you match automatic identification system data with satellite imagery to identify publicly tracked vessels? Automatic identification systems, commonly referred to as AIS, transmit a ship’s position and alerts others to its whereabouts. While originally designed as a collision avoidance mechanism, AIS is regularly used […]

AIS and the Challenges of Tracking Vessels at Sea

At Global Fishing Watch, we hear it all the time: “Tracking commercial fishing vessels from satellites is such a great idea, and it seems so easy!” In fact, we’ve received a few questions from our readers asking us why this isn’t just a simple hack of publicly available data.
