Figure 1 This whale track (in blue) begins in the top right hand corner. Arrows indicate direction of travel. The pink boat, a small tourist zodiac, starts in the bottom left, goes up to the top right before our whale enters the scene, and shortly after we began tracking the whale, came back around and started to follow it. The green boat, a larger charter fishing/whale watching tour boat, arrived from the bottom left, spotted the whale around the 13:01 time stamp, and turned to follow. The question to explore here is whether the whale’s large turn is a normal pattern, or a reaction to the vessels present. (tracklines taken at Boiler Bay)
