Extremely shallow areas still have some of the green wavelengths of light. This creates the green-blue hues that we see in areas around islands and reefs, such as those in the Caribbean Sea. Of course, as we go deeper and deeper, eventually there's no sunlight at all.

This glorious blue colour is due partly to the reflection of the blue skies and partly to the fact that the sea does not contain large quantities of solid matter such as plankton, mud and dust floating in the water. The way in which the Greek Sea sparkles is like no other the world over.
Hawaii's ocean water is nutrient deficient. This is common in tropical areas with warm surface water temperatures. A lack of nutrients means there are fewer phytoplankton and algae in Hawaii's water, which makes it more blue.
The Weddell Sea has been claimed by scientists to have the clearest waters of any ocean in the world. Described by a historian as “the most wretched and dismal region on earth”, due to the flash freezes that caught Shackleton's ship, its clarity is only belied by the sheer depth of the ocean below.
Be it a honeymoon in Bora Bora, a friends-only weekend away in the Bahamas, or a family trip to the Greek Islands, that blue water has us all hooked. But how, exactly, does it get to be that unbelievable hue anyway? The reason the ocean is blue is due to the absorption and scattering of light, NASA explains.
The reason behind this color choice has to do with practicality. In the old times, Greek housewives would use a cleaning agent called loulaki (blue powder in English) which came in the form of talcum powder. It was widely and cheaply available across Greece.
The Adriatic Sea is fed by several rivers, including the Po, which is the longest river in Italy, and the Neretva in Croatia, which is the largest river in the eastern part of the Adriatic basin. These rivers carry sediment and nutrients that contribute to the colour and clarity of the water.
1. The Maldives. The Maldives, located in the Indian Ocean, have around 1,190 islands and sandbanks. A lagoon with crystal clear water encircles all the islands, which are protected by a reef structure that is home to an array of underwater life.
Because the tropics have warm surface water, even in the winter, the thermocline never goes away, and the nutrients stay trapped down below in the depths. So even with ample sunlight, phytoplankton growth is severly limited. In the tropics, predators like coral make good use of what little plankton there is.
Why Is The Maldives Water So Blue And Clear? Maldives water is known for its abundance of coral reefs. The waters of Maldives are known to consist of coral reefs and “phytoplankton” which absorbs blue and green colours from the sunlight due to which it causes clean water and you can see crystal clear reflection.
Blue Lake, New ZealandBlue Lake has underwater visibility up to 70 to 80 meters or 230 to 260 feet down, which is insane! Apart from being the world's clearest lake, it's also the clearest body of natural freshwater. The water in Blue Lake is comparable to distilled water based on laboratory measurements.
Ocean salt primarily comes from rocks on land and openings in the seafloor. Salt in the ocean comes from two sources: runoff from the land and openings in the seafloor. Rocks on land are the major source of salts dissolved in seawater. Rainwater that falls on land is slightly acidic, so it erodes rocks.
