The group interacted with dozens of whales over the class of 4 days in Antarctica. They made use of specialised camera drones to evaluate entire body dimension and suction-cupped tags slapped on to the animals’ backs by using a lengthy pole to history the best way they move though capturing whale’s-eye-watch video clip.
