Global Fishing Watch New Night Light Layer Global Overview (image) Global Fishing Watch Share Print E-Mail Caption Global Fishing Watch's new night light vessel detection layer uses satellite imagery from the US 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.
