What makes those tropical ocean waters so turquoise blue?

Answer 1

its usually that they are cleaner, warmer, and shallower than other areas so they reflect more of the blue from the sky.

Answer 2

I think it has to do with having white sand beneath a layer of clean ocean water. Sometimes we get turquoise waters in California when the ocean is calm for a few days and you are looking at a patch of water thats over white sand. But maybe there's another explanation.

Answer 3

I observed waters at a Tobago coastline, referred to as Bucco Reef, like what you're asking approximately. It became a mix of the positive turquoise coloration aquatic flora, under the crystal clean waters, and coated by way of an exquisite vivid blue sky. at that element I taught that this could be heaven. good success.

Answer 4

Actually, clear blue water--especially in the tropics--is usually a sign of a nutrient-poor environment. Such warm waters have less dissolved oxygen and nutrients, which means less algae, which means less zooplankton that feeds on the algae, and thus waters that are clear.

This doesn't mean that they're lifeless by any means--coral reefs and the animals that live on them thrive in such waters--but it does mean that the waters are not quite as rich as in other regios.

Answer 5

because the water is so clear, shallow, and has white sand or coral beneath it, it reflects the sky much more than deeper ocan, as well as the fact that the temperatures are higher- this makes the water more receptive to the sky's color, too.
