From: Identification of suspicious behavior through anomalies in the tracking data of fishing vessels
Significant anomalous locations (green dots) in the proximity of Exclusive Economic Zones (EEZ) and Marine Protected Areas (MPAs). (a)-(h) Regional distribution of anomalous locations. Panels (a), (c), (e), (g) depict the location of the anomalies, while (b), (d), (f), (h) describe the number (color) and fraction (fraction of the pie) of observed silence anomalies in each 1° × 1° grid cell. Regions correspond to the Northeast Atlantic Ocean (a), (b), Northwest Atlantic Ocean (c), (d), Southern Mediterranean Sea (e), (f) and Western Pacific Ocean (g), (h). Grey contours and light blue areas represent, respectively, the limits of the Exclusive Economic Zones and the zones declared Marine Protected Areas. (i) Normalized frequency of observed anomalies (number of anomalies divided by the global number of anomalies) in cells located at a distance d from the shore
