How do you measure how high a dolphin jumps?

To measure how high a dolphin jumps, you can use a combination of visual observation and technology. One common method involves using a video camera to record the jump, and then analyzing the footage to determine the height by referencing a known scale, such as a buoy or a marker in the water. Alternatively, sonar equipment can be used to measure the distance from the water's surface to the peak of the jump. This data can then be used to calculate the height of the jump accurately.
