(a) Encounter with three whales forming two subgroups indicated by color (red and blue). Shading represents time, from light (start of track) to dark (end of track). Gaps in detections for an individual are represented as a dashed line. Black triangles denote positions of 4-hydrophone receivers. (b) Number of subgroups per encounter for all deployments by total number of whales present, color represents counts. (c) Distribution of mean number of whales across subgroups per encounter.
