Ocean optics is the study of how light interacts with water and the materials in water. Although research often focuses on the sea, the field broadly includes rivers, lakes, inland waters, coastal waters, and large ocean basins. How light acts in water is critical to how ecosystems function underwater.
Other hypotheses include the interference patterns of intersecting waves creating a raised curve acting as a lens, but would not explain the source of light. [2] David Lewis speculated that te lapa may originate from luminescence of organisms, or related to deep swell, ground swell , or backwash waves from reefs or islands.
Milky sea effect off the coast of Somalia in the Indian Ocean. Milky seas, sometimes confused with mareel, are a luminous phenomenon in the ocean in which large areas of seawater (up to 100,000 km 2 or 39,000 sq mi [1]) appear to glow diffusely and continuously (in varying shades of blue).
ARCA's deep-sea sensors near Sicily detect a highly energetic neutrino, potentially revealing secrets about cosmic phenomena and the universe's hidden mysteries. Scientists May Have Found Signs of ...
Water clarity is a descriptive term for how deeply visible light penetrates through water. In addition to light penetration, the term water clarity is also often used to describe underwater visibility. Water clarity is one way that humans measure water quality, along with oxygen concentration and the presence or absence of pollutants and algal ...
But while a relaxing vacation is a must, it’s important to be mindful of possible hidden beach dangers that lurk between the sand and ocean floor. Show comments Advertisement
Sudden loss of underwater visibility , which can cause disorientation and a diver getting lost under an overhead. Stirring up silt or other light loose material, either by natural water movement or by diver activity, often due to poor trim and finning skills. Appropriate trim, buoyancy and propulsion techniques.
Ocean currents can flow strongly enough to make diving difficult. This is usually reasonably predictable. In some places the local topography can induce enough turbulence to be dangerous. River and inland water currents can be strong and dangerous in areas of high gradient.
