Loitering is when a single vessel exhibits behavior indicative of a potential encounter event. Loitering is estimated using automatic identification system (AIS) data, including vessel speed, duration in a given location, and distance from shore. Loitering occurs when a vessel travels at average speed of < two knots, while at least an average of 20 […]
Tracking refrigerated cargo ships, commonly called reefers, can help address illegal fishing in the Gulf of Guinea Transshipment, or the transfer of fish from one vessel to another, is a vital part of the global commercial fishing industry. It touches a wide variety of seafood products, from bigeye and skipjack tuna all the way to […]
User Guide English | Español | Français | Portuguese |ä¸æ–‡ Menu Introduction The Global Fishing Watch map is the first open-access online platform for visualization and analysis of vessel-based human activity at sea. Powered by satellite technology and machine learning, the map merges multiple types of vessel tracking data to provide a view of global […]
Platform Updates 2025 March – Vessel Viewer and Vessels API – New vessel identity fields from TMT New vessel identity information provided by TMT is now available in vessel profiles in Vessel Viewer, including vessel gear type, year built, length, depth, gross tonnage and photo, when available Global Fishing Watch and TMT are pleased to […]
NGO collaboration will help fishery managers ensure transfer of catch is both legal and verifiable The transfer of fresh catch from fishing vessels to refrigerated cargo ships is an important but often opaque part of the industrial fishing sector. A new public global monitoring portal is a turning point in efforts to manage this activity. […]
Global Fishing Watch has launched an improved version (v3.0) of our automatic identification system (AIS) data pipeline. The AIS data pipeline is the series of processes that we use to convert the raw satellite AIS ingested data to the data products, such as machine learning estimates of fishing activity, identity data that combines merged external […]
Global Fishing Watch Carrier Vessels GO TO THE PORTAL About Global Fishing Watch Carrier Vessels Transshipment is a vital part of the global fishing industry, but it often takes place far out at sea, making it challenging for authorities to determine whether the catch being transferred is both legal and verifiable. To improve the understanding […]
Datasets and Code: Transhipment Thanks to a practice known as transshipment—the transfer of catch between vessels—fishers can stay at sea for months at a time without ever having to take a costly and time-consuming trip back to port to offload catch. However, transshipment also obscures the seafood supply chain from hook to port and hobbles […]

By openly publishing our APIs, we aim to transform global collaboration and catalyze solutions to address the ocean’s most complex problems. Building innovative ways to access and integrate our dynamic data Global […]
An encounter is anywhere that a refrigerated cargo vessel meets up with a fishing vessel while at sea. Encounters may indicate potential transshipment activity between two vessels that both appear in the automatic identification system (AIS) data source Our algorithm estimates an encounter event when two vessels were within 500 meters for at least two […]
