Arufura Sea, January, 2018. Vessel Monitoring System (VMS) data from Indonesia is shown in the Global Fishing Watch map as yellowish dots. This image is overlayed with data from NOAA's satellite-based Visible Infrared Imaging Radiometer Suite (VIIRS) which detects many vessels not broadcasting VMS. VIIRS-detected vessels are shown here as blue sailboats. (Global Fishing Watch 2018)
