The Ocean Has a Secret Conveyor Belt

Create an immersive earth science short explaining deep ocean circulation. Begin with a sweeping drone-like camera move above dark blue waves, then descend beneath the surface in a seamless vertical transition. Use a wide lens for vast underwater scale and a macro lens for sinking cold water particles. Visualize currents as luminous ribbons flowing around the globe, with elegant map overlays integrated into the water. Use moody teal lighting, soft caustic patterns, and cinematic documentary realism. Show temperature and salt changing water density through clear visual comparisons. Finish with a calm overhead view connecting polar seas, deep trenches, and distant coastlines.
