What Actually Makes Some Ocean Water Such a Vibrant Turquoise Color-the Science Behind That Dreamy Shade
"When light shines through water, colors with longer wavelengths are absorbed by the water, with the longest wavelengths absorbed first. Blue and violet have the shortest wavelengths of visible light, so they are able to penetrate the deepest."
"The waters around the islands are shallower and almost completely free of plankton, which causes other waters to turn a more greenish hue. Additionally, these lighter blue waters are usually home to heavier sand and sediment, which churn up less, leaving the waters clearer."
"These destinations tend to experience less 'upwelling,' which NOAA explains is when the wind blows across the ocean surface, pushing the water away, and deeper water rises up to replace it."
Turquoise waters in vacation destinations are influenced by light absorption and water clarity. Longer wavelengths are absorbed first, allowing blue and violet to penetrate deeper. In shallower areas, like parts of the Caribbean and South Pacific, the absence of plankton and heavier sand contribute to clearer waters. These regions also experience less upwelling, resulting in calm waters that enhance the vibrant blue appearance. Most oceans are dark beyond certain depths, but specific locations maintain their stunning azure color due to these unique conditions.
