Water color can reveal physical, chemical and bacteriological conditions. In drinking water, green can indicate copper leaching from copper plumbing and can also represent algae growth. Blue can also indicate copper, or might be caused by syphoning of industrial cleaners in the tank of commodes, commonly known as backflowing.
As blue and red light are absorbed, green light remains. Ocean regions with high concentrations of phytoplankton have shades of blue-to-green water depending on the amount and type of the phytoplankton. [15] [16] Green waters can also have a combination of phytoplankton, dissolved substances, and sediments, while still appearing green.
Green Lakes State Park is a New York State Park located east of Syracuse in the Town of Manlius. The park is strikingly scenic, and has a "masterpiece" [2] golf course designed by Robert Trent Jones very early in his career. Green Lake itself is perhaps the most studied meromictic lake—one in which layers of water do not mix—in the world. [3]
The blue water environment extends from the outer edge of the green-water zone to the deep ocean of the world. A blue-water navy can project its nation's power throughout the world. The blue water policy was a long-standing political philosophy in Britain in the 18th century, which sought to advance British power through use of the Royal Navy ...
With its vivid turquoise, green and blue waters, it’s no surprise Lake Salda is often promoted as the “Maldives of Turkey.” According to scientists, it’s also the only place on Earth that ...
In nature, the color may also be modified from blue to green due to the presence of suspended solids or algae. In industry, near-infrared spectroscopy is used with aqueous solutions as the greater intensity of the lower overtones of water means that glass cuvettes with short path-length may be employed.
[79] [80] In green light, the cells accumulate more phycoerythrin, which absorbs green light, whereas in red light they produce more phycocyanin which absorbs red. Thus, these bacteria can change from brick-red to bright blue-green depending on whether they are exposed to green light or to red light. [81]
To distinguish the color green from blue, they used to name it sug-kök – "water-blue", no matter how strange it may sound. [citation needed] Although note that kök was used for green primarily, they used sug-kök only if they needed to. Thus, blue was kök, and green was kök, sug-kök.
