  1. The distance between the actual location of the detected individual and the GPS location of the drifter is sum of the following four factors: (i) the detection range of receivers, (ii) GPS positioning errors, (iii) the distance traveled by the drifter during the time between GPS positioning and signal detection, and (iv) the effect of the depth at which a tagged individual stayed.
