The Real Reason the Ocean Is Blue (It Is Not Just Reflected Sky)

Ever wondered why the ocean looks so blue? It’s not simply a mirror reflecting the sky.

You’ll also learn how factors like chlorophyll from algae, sediments, and other suspended particles can push the color toward green, turquoise, or even brown. Along the way, you’ll get easy, practical tips for spotting these effects yourself, understanding what color changes can mean, and steering clear of the most common myths.
