Life is a characteristic that distinguishes physical entities that have biological processes, such as signaling and self-sustaining processes, from those that do not, either because such functions have ceased (they have died), or because they never had such functions and are classified as inanimate.Various forms of life exist, such as plants, animals, fungi, protists, archaea, and bacteria Hydrothermal vents are the result of seawater percolating down through fissures in the ocean crust in the vicinity of spreading centers or subduction zones (places on Earth where two tectonic plates move away or towards one another). The cold seawater is heated by hot magma and reemerges to form the vents. Seawater in hydrothermal vents may. These findings suggest a higher ecosystem complexity at the vent site, which may have facilitated the higher diversity of copepods in the otherwise unaffected motile epibiont community. In the laboratory experiment, P. oceanica photosynthesis increased with decreasing pHT (7.6, 6.6, 5.5), which induced an elevated pH at the leaf surfaces of up.

The discovery of deep-sea hydrothermal vents in the late 1970s expanded our knowledge of the extent of life on Earth (Corliss et al. 1979).Hydrothermal-vent environments include positively buoyant and neutrally buoyant (lateral) hydrothermal plumes (∼2 °C), low-temperature hydrothermal fluids (∼5-100 °C), high-temperature hydrothermal fluids (∼150-400 °C), sulfide rock, basalt. Chemical oceanographers also focus on how pollutants affect seawater composition. They may study the unusual and sometimes toxic fluids released by hydrothermal vents in the ocean floor. Ocean acidification is a key topic in chemical oceanography.

According to the paper published in PLoS ONE, this is the first discovery of a hydrothermal vent ecosystem in the Southern Ocean though many others have been recorded in warmer waters worldwide The discovery of hydrothermal vents and chemosynthetic organisms in the volcanic ridges in the rift in 1977 was a revolutionary discovery in science that changed our understanding of life processes. For the first time, scientists found evidence that life could be sustained from chemicals coming out of the Earth's crust, rather than the light. Microbes unique to this environment could provide insight into metabolic processes, strategies for growth, and survival of life forms in the subsurface of solar bodies with a water history. For example, Jupiter's satellite Europa may harbor a liquid ocean with life-supporting hydrothermal systems beneath its icy shell
