Table S5: The number of seconds and encounters with porpoise detections on hydrophone clusters during the deployment of mitigation measures and baseline periods used to examine directionality of porpoise movements. The distribution of differences in bearings was tested using Rayleigh Tests, initially for uniformity, and then for uniformity against a unimodal alternative with a specified mean direction of 0°.
