The team interacted with dozens of whales around the study course of four times in Antarctica. They utilised specialized digicam drones to measure body dimensions and suction-cupped tags slapped onto the animals’ backs which has a prolonged pole to document just how they go whilst capturing whale’s-eye-perspective video clip.
