Web9 nov. 2024 · The theory of plate tectonics predicted the existence of these hydrothermal vents, but they were discovered only in 1977. Since then the sites have attracted teams of scientists seeking to understand how life can thrive in what would seem to be intolerable or extreme conditions of temperature and fluid chemistry. Life has traditionally been seen as driven by energy from the sun, but deep-sea organisms have no access to sunlight, so biological communities around hydrothermal vents must depend on nutrients found in the dusty chemical deposits and hydrothermal fluids in which they live. Previously, Benthic oceanographers assumed that vent organisms were dependent on marine snow, as deep-sea organisms are. This would leave them dependent on plant life and thus the sun. … m\u0026t bank dual highway hagerstown

WebHydrothermal Circulation The discovery of hot springs on the ocean floor during the 1970s was one of the most exciting events in the history of oceanography. Although hydrothermal activity at mid oceanic ridges (MOR) was predicted as part of the plate tectonics theory, it took more than two decades before hydrothermal vents were actually found. WebAs was mentioned, the area on the surface where these fluids are ejected is called a hydrothermal vent. The vent is, in itself, a unique consequence of the interaction between hydrothermal fluids and seawater. The vent is …
