5.3 meters below water surface.

Step-by-step explanation:

To find out the position of the dolphin's friend relative to the surface of the water we will subtract dolphin's friends position from dolphin's position.

-5.3 means below the water surface. Therefore, position of dolphin's friend is 5.3 meters below water surface.
