Ocean color is the branch of ocean optics that specifically studies the color of the water and information that can be gained from looking at variations in color. The color of the ocean , while mainly blue, actually varies from blue to green or even yellow, brown or red in some cases. [ 1 ]
Halāhala (Sanskrit हलाहल) or Kālakūṭa (Sanskrit कालकूट, lit. ' poison of death ') [1] [2] is the name of a poison in Hindu mythology.It was created from the Ocean of Milk when the devas and the asuras churned it (see Samudra Manthana) in order to obtain amrita, the nectar of immortality.
For instance, dissolved organic compounds called tannins can result in dark brown colors, or algae floating in the water (particles) can impart a green color. [11] Color variations can be measured with reference to a standard color scale. Two examples of standard color scales for natural water bodies are the Forel-Ule scale and the Platinum ...
Ocean color is a reflection of what’s in the water itself. Ocean water absorbs most colors, and if there’s little life in the water itself, blue light is reflected back.
The color of the ocean has changed significantly over the last 20 years and human-caused climate change is likely responsible, according to a new study.. More than 56% of the world’s oceans have ...
In Hindu mythology, the devas and the asuras performed the churning of the ocean of milk (Samudra Manthana) in order to obtain amrita, the elixir of immortality. During this process, fourteen jewels emerged from the ocean. Among the first few treasures that emerged was the kaustubha, described to be an "excellent gem, the lotus-hued ruby".
The color of the water as seen by satellites is known as ocean color. While ocean color is a key theme of ocean optics, optics is a broader term that also includes the development of underwater sensors using optical methods to study much more than just color, including ocean chemistry, particle size, imaging of microscopic plants and animals ...
Most of the ocean is blue in color, but in some places the ocean is blue-green, green, or even yellow to brown. [64] Blue ocean color is a result of several factors. First, water preferentially absorbs red light, which means that blue light remains and is reflected back out of the water.
