The dispersal of hydrothermal fluids throughout the global ocean at active vent sites creates hydrothermal plumes. Hydrothermal deposits are rocks and mineral ore deposits formed by the action of hydrothermal vents. Hydrothermal vents exist because the Earth is both geologically active and has large amounts of water on its surface and within ...
Invoking images of the open ocean's surface, the imagination can conjure up an endless empty space. A flat line parting the blue below from the blue above. But in reality a diverse array of species occupy this unique boundary layer. A tangle of terms exist for different organisms occupying different niches of the ocean's surface.
Though California is a notable example of the marine layer, these atmospheric phenomena exist in several other places around the world. Marine layers often form on the west coasts of continents, where upwelling usually occurs, and where there is a relatively warm air mass moving over a cool body of water. [ 2 ]
Pelagic zones. The ocean can be conceptualized as being divided into various zones, depending on depth, and presence or absence of sunlight.Nearly all life forms in the ocean depend on the photosynthetic activities of phytoplankton and other marine plants to convert carbon dioxide into organic carbon, which is the basic building block of organic matter.
From shallow waters to the deep sea, the open ocean to rivers and lakes, numerous terrestrial and marine species depend on the surface ecosystem and the organisms found there. [28] The ocean's surface acts like a skin between the atmosphere above and the water below, and harbours an ecosystem unique to this environment.
Why people pick the ocean as their final resting place. April 12, 2022 at 8:00 AM. ... There are many reasons why people want to be buried at sea. For some, the decision is financial: A sea burial ...
Ocean stratification is the natural separation of an ocean's water into horizontal layers by density. This is generally stable stratification , because warm water floats on top of cold water, and heating is mostly from the sun, which reinforces that arrangement.
Two new studies suggest once again the importance of getting a good night's sleep for good health over a lifetime, as scientists pursue new understandings of restorative deep sleep.
