The color of the water in the deep sea was affected by many factors. In terms of optical properties, water molecules had different absorption abilities for different colors of sunlight. Red, orange, and yellow light were absorbed by the ocean, while blue light was finally absorbed. Therefore, as the depth of the sea increased, the proportion of blue light increased relatively, and the sea water looked more and more blue. The floating components in the seawater, the depth of the sea, and the characteristics of the clouds also affected the color of the deep sea. Moreover, there were different colors of creatures at different depths. The creatures that could emit light would also affect the visual color of the deep sea.
The color of the deep sea water is usually a very deep blue or dark green, sometimes almost black. This was mainly due to the absorption and scattering of light by water molecules. The water molecules in the seawater would absorb the red and yellow frequencies of visible light, while the blue-green frequencies could penetrate deeper water layers. The blue light was more likely to scatter or reflect, making the seawater look blue. In addition, microorganisms (such as algae) and suspended matter in the deep sea would also affect the scattering of light, further enhancing the blue effect of seawater. At the same time, the angle and intensity of the light, the quality of the seawater, the temperature, the amount of nutrients, and the ph of the water would also affect the color of the deep sea water.
Deep sea cucumbers came in a variety of colors, such as khaki, dark green, grayish brown, brown, light blue, green, yellow, and so on. Sea cucumbers would change their body color according to their habitat. For example, sea cucumbers that grew in rocky areas were mostly brown, while sea cucumbers that grew in bathing areas were mostly brown. Sea cucumbers in the same sea area had different colors.
The Deep Sea Moon was a bluish-white color. In the deep sea, after the light was absorbed and scattered by the water, the blue light had a relatively short wave-length and could penetrate the water layer better. Therefore, the light in the deep sea was mainly blue, which was one of the reasons why the moon in the deep sea was blue and white.
Deep sea blue was the color of the deep sea. There was a little green in the blue, and the color was rich and deep. It was a color that had experienced time and could stand the test of time. It was like a bottomless sea, calm with a hint of melancholy, and at the same time, it had the vastness of the sea. The brightness was low, the saturation was moderate, calm but not dull, and the color tone was cold but not dull. The little green tone added some vitality and mystery to the color. It was a high-class and artistic color that was often used in the design of cars, homes, home accessories, clothing, jewelry, bags, and electronic products.
The Deep Sea Moon was a bluish-white color. In the deep sea, due to the absorption and scattering of light by water, the length of blue light was relatively short and could penetrate the water layer better. Therefore, the light in the deep sea was mainly blue, which made the Deep Sea Moon appear blue-white. Moreover, the bioluminosity in the deep sea would also form a blue light, which would further affect the visual color of the deep sea moon, making it look more blue-white. Moreover, the blue light would gradually weaken when it spread in the water, so the moon observed in the deep sea would be dimmer than on land.
The water of the Black Sea was black. From many aspects, the average depth of the Black Sea was 1300 meters, and a deeper depth would make the sea water look darker. Secondly, there was more silt at the bottom of the Black Sea, and many rivers around it flowed into the sea. The sea passage was long and narrow, and the water was not smooth. The silt carried by the rivers piled up, causing the Black Sea to look darker from the outside. In addition, the seawater below 200 meters of the Black Sea was difficult to circulate with the outside world. It was in an anoxic-deficient environment and produced a large amount of hydrogen sulphide. The hydrogen sulphide mixed with the seabed silt, causing the Black Sea to appear black as a whole. However, the black sea water was clear and transparent.
There were several reasons why the water in the deep sea was black. First of all, the dissolved substances in the deep-sea water, such as salt and minerals, would increase the density and refraction index of the water, which caused the light to be more scattered when it traveled in the water. It was difficult for the light to reach the observer's eyes directly, making the water look black. Secondly, suspended matter was one of the factors that caused the deep sea water to turn black. There were a large number of suspended organic and mineral particles in the deep sea, such as algae, planktons, and deposits. These suspended matter would absorb and scatter light, preventing light from passing through the water, making the water look darker. In addition, the organisms in the deep sea also had an impact on the color of the water. There were many organisms in the deep sea that had bioluminescent abilities. They emitted blue or green light. In the deep sea, due to the absorption and scattering of light, red and yellow light were more easily absorbed, and blue and green light were more easily absorbed through the water. Therefore, when observing the deep sea, blue or green light was seen, which made the water appear black.
Based on context alone There were several main reasons for the darkening of deep sea water. One was the absorption and scattering of light. As the depth of the sea increased, the light gradually weakened. Water molecules and various dissolved substances (such as salt) in seawater would absorb and scatter light, especially for long-wave light (such as red light). In the deep sea, there was very little light that could reach them. The only light that could reach them was short-wave blue and purple light, which were extremely weak. When almost no light was emitted, it would appear black. The second was the deep sea environment. The lack of light in the deep sea caused the ecosystem here to be very different from that in the shallow sea. There was not enough light to support photosynthesis, the species and distribution of organisms were less, and the lack of organisms that could produce color or reflective substances also made the deep sea look darker.
"Deep Sea Trek"(also known as "Beautiful Water World") was an underwater adventure game with an extraterrestrial ocean planet as the stage. The player takes on the role of a wrecked astronaut and survives on a planet covered in water. In the game, players needed to explore the ocean world, manage the oxygen supply, collect resources, forge equipment, build a base, and solve the mysteries of the planet. The game was released on PC and PlayStation 4 on January 23, 2018, and was ranked fourth in the Top 10 Games of 2018.
