New data reveals suspected vessel rendezvous at sea and sheds light on the ‘dark’ fleet
Global Fishing Watch (GFW) has increased ocean transparency by releasing the first-ever ‘live’ global view of likely transshipping at sea — a practice that can mask illegal fishing activity, and imagery of night-time fishing and its location, exposing vessels often hidden from other monitoring systems.

New encounters layer global overview
Global Fishing Watch’s new encounters layer reveals for the first time where and when thousands of vessels are involved in close encounters at sea. To detect pairs of vessels meeting at sea, analysts applied machine learning algorithms to more than 30 billion Automatic Identification System (AIS) messages from ocean-going boats to find tell-tale transshipment behaviour, such as two vessels alongside each other long enough to transfer catch, crew, or supplies. © Global Fishing Watch New night light vessel detection map
Global Fishing Watch’s new night light vessel detection layer uses satellite imagery from the U.S. National Oceanic and Atmospheric Administration (NOAA) to reveal the location and activity of brightly lit vessels operating at night. Because the vessels are detected solely based on light emission, we can detect individual vessels and even entire fishing fleets that are not broadcasting AIS and so are not represented in the AIS-based fishing activity layer . © Global Fishing Watch
