From: Identification of suspicious behavior through anomalies in the tracking data of fishing vessels
A global dataset of silence anomalies observations. (a) Geographical extent of the number of significant anomalies starting at each 1° lat × 1° lon grid cell. (b) Distribution of the number of anomalies observed in each grid cell. c Density plot of the fraction of significant anomalies, computed as the sum of significant anomalies in each grid cell divided by the number of locations of vessels with at least one anomaly in that grid cell, as a function of the total number of anomalies. (d) Geographical extent of the fraction of anomalous locations. Grey contours on the maps represent the limits of Exclusive Economic Zones
