Why Is the Ocean Blue?

The video explains why the ocean appears blue, debunking the common belief that it is due to sky reflection. Instead, the ocean's color is primarily due to water's inherent properties and its absorption of light. Rayleigh scattering causes the sky to be blue, but water absorbs red, yellow, and green light more effectively, allowing blue light to penetrate deeper. Variations in ocean color can occur due to algae or river silt. Some marine animals have adapted to deep water by being red, making them less visible. The video concludes with acknowledgments to contributors.
