How light acts in water is critical to how ecosystems function underwater. Knowledge of ocean optics is needed in aquatic remote sensing research in order to understand what information can be extracted from the color of the water as it appears from satellite sensors in space. The color of the water as seen by satellites is known as ocean color ...
Ocean color data is a key tool for research into how marine ecosystems respond to climate change and anthropogenic perturbations. [29] One of the biggest challenges for ocean color remote sensing is atmospheric correction, or removing the color signal of the atmospheric haze and clouds to focus on the color signal of the ocean water. [30]
This means that the color of the water is influenced by the angular distribution of the light field and by the nature and quantity of the substances in the medium, in this case, water. [2] Thus, the values of remote sensing reflectance, an AOP, will change with changes in the optical properties and concentrations of the optically active ...
Human-driven climate change is altering the world’s oceans, including their very color.
The color of a water sample can be reported as: Apparent color is the color of a body of water being reflected from the surface of the water, and consists of color from both dissolved and suspended components. Apparent color may also be changed by variations in sky color or the reflection of nearby vegetation.
In other words, as light passes through a greater distance of water color is selectively absorbed by the water. Color absorption is also affected by turbidity of the water and dissolved material. Water preferentially absorbs red light, and to a lesser extent, yellow, green and violet light, so the color that is least absorbed by water is blue ...
The luminescent glow is concentrated on the surface of the ocean and does not mix evenly throughout the water column. [8] A culture of luminous bacteria, showing the diffuse uniform light that characterizes milky seas. In 1985, a research vessel in the Arabian Sea took water samples during milky seas.
