An April 2007 exploration of the deep-sea vents off the coast of ..

The occurrence of "natural" lighton the dark seafloor has great significance, because it implies that photosynthesismay be possible at deep-sea geothermal vents.

It is happening at a deep-sea vent more than 8,000 feet below the surface of the ocean.

Hydrothermal vents in the deep oceans provide a fascinating view into a part of our planet that was only vaguely imagined a quarter-century ago and is still not wellunderstood today. Beyond their intrinsic interest, vents may play an important roleregulating the temperature and chemical balance of the oceans; help us investigatethe origin of life on our planet and elsewhere in our solar system; and are a potentialsource of recoverable resources (the are base metal deposits in the making).

Researchers find photosynthesis deep within ocean - …

Deep-sea vents are also known as deepwater seeps, deep-sea springs, and hydro-thermal vents.

Oceans have existed, more or less, since the beginning of Earth's history. Life on thebottom of the oceans is actually well protected from variability on the surface of theEarth (climate variations etc.), and thus some scientists think that these deep seahydrothermal vents might be the most ancient sites of life on Earth. Although theirdiscovery does by no means imply that life originated in the depths of the oceans, thesedeep sea vents are nonetheless an alternative site.

Scientists also have found creatures that defy our conventional perceptions of sea life. , for example, are typically thought of as animals that survive only in warm, relatively shallow waters, and in symbiosis with algae that convert sunlight into nutrients. But corals also exist in cool, dark waters, at depths of more than 4,500 meters. These deep-sea corals, which include species of Paragorgia, Lophelia, and Primnoa, feed on microorganisms and “marine snow,” particulate organic matter that drifts down through the layers of ocean water and provides an important food source for bottom-dwellers. Similar to warm-water corals, their deep-sea counterparts also provide important habitat and serve as a source of food for creatures such as anemones, rockfish, shrimp, and Hawaiian monk seals.

In 1977, a group of scientists researching the theory of plate tectonics, traveled to the floor of the equatorial Pacific Ocean and discovered something that could possibly explain how life began on this planet.

It is possible that GSB1 also uses light emitted from chemical reactions for photosynthesis, according to Van Dover. that deep-sea vents have more light in the visible spectrum than would be expected based solely on the water's temperature, and some of this light may come from chemiluminescence.

According to the Census of Marine Life, the deep sea is so little explored that scientists investigating depths greater than 3,000 meters have a 50 percent chance of discovering new creatures. Thus, the coming years of marine research promise to continue to be not only awe-inspiring and but also fundamental to expanding our knowledge of the great vastness of the world’s oceans.
