The Ocean Has a Secret Sound Map

Create an awe-filled oceanography lesson explaining how scientists map the seafloor with sonar. Open on a dramatic underwater wide shot with particles drifting through deep blue water, captured with a virtual 18mm lens and a slow forward glide. Transition through a match cut to a marine science creator in a US research lab, filmed at a 50mm medium angle beside a glowing digital ocean map. Use cyan practical light, soft rim lighting, clean infographic overlays, and bassy but calm sound design. Show a sonar pulse traveling downward, reflecting from the seafloor, and returning to the ship. Explain that timing the echo reveals depth, then end with a zoom across a colorful bathymetric map.
