Each line included two stationary acoustic transmitters (Tag) located approximately 250 m apart. ‘Start’ and ‘end’ is start and end dates of range testing trial, depth is approximate water depth (meters) at stationary transmitters, and duration is length of experimental trial (days). Dates are yyyy-mm-dd format. The total number of detections (tot. detections) was calculated by summing the number of detections on all receivers at each station during the trial. Average number of detections per day (detections day⁻¹) was calculated by dividing the number of detections recorded for the trial by the duration of the experimental trial. The maximum distance an acoustic transmitter was detected at each site (max distance detected) is reported for each transmitter. See Fig. 1 for locations of stations
