Well bye and thanks for letting me use this program. All other living things in the midnight zone are nourished by these bacteria. The average depth of the seafloor is about 4, meters 14, feet , and the deepest part of the ocean is about 11, meters deep 36, feet. Today, however, new technology promises to reveal how light operates in the ocean and how it creates a unique environment and assorted phenomena that ocean life is adapted to. The given layout depicts the information about penetration of light into the four different zones of ocean at different temperature Celsius at the depth of metre from the surface of ocean.
Ocean Light Zones
Reactions other than the following of a certain light intensity were thus involved in the vertical migration of these layers. Most fish live in this zone. Some animals eat only plants; they are called herbivores. Plants are found only in the sunlit zone where there is enough light for photosynthesis, however, animals are found at all depths of the oceans though their numbers are greater near the surface where food is plentiful. Water is transparent to the wavelengths of electromagnetic radiation that fall within the visible spectrum and is opaque to wavelengths above and below this band. Oceanographers divide the ocean into five broad zones according to how far down sunlight penetrates: Light Penetration in the Ocean.
Calculation of the ambient light of the acoustic scatter In cases where mesopelagic acoustic scatter was shallower than the deepest light measurement, we set the ambient light of the acoustic scatter equal to the measured light at same depth. Blue light penetrates the farthest, but only to about meters in the open ocean. This also happens to the light reflected as glare from the sea surface or a wet road. Animals living near well-lit surface regions have eyes similar to terrestrial species. In enhancing understanding of this phenomenon, our results should improve the ability to predict and model the dynamics of one of the largest animal biomass components on earth, with key roles in the oceanic biological carbon pump and food web.
