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 ]
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 ...
The increasing use of digital cameras has reduced the learning curve of underwater flash significantly, since the user can instantly review photos and make adjustments. Color is absorbed as it travels through water, so that the deeper the observer, the less reds, oranges and yellow colors remain. The strobe replaces that 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.
The standard measurement for underwater visibility is the distance at which a Secchi disc can be seen. The range of underwater vision is usually limited by turbidity. In very clear water visibility may extend as far as about 80m, [18] and a record Secchi depth of 79 m has been reported from a coastal polynya of the Eastern Weddell Sea ...
Today, this land largely makes up the coastal shelf that is currently under development as North Sea nations install offshore wind farms to combat climate change. This vast expansion of green ...
These underwater mollusks have inspired scientists to make one of the strongest adhesives on the market. Researchers have cracked how mussels attach to wet surfaces, and have replicated it into an ...
