WebApr 8, 2024 · The MHV is an asymmetric volcano composed of two summits in the center, rugged mounds in the west, and flat regions in the east. Two hydrothermal vents, Devil Chimney and Witch Mound were discovered through acoustic flares and a high backscatter intensity in the eastern flank. WebThe vents expel a fluid that was heated to extreme temperatures when seeping through the Earth's crust from the ocean. Maggie explains, 'Hydrothermal vents are like hot springs on the seafloor. As tectonic plates of oceanic crust move apart, the crust is stretched, and in places it breaks, forming cracks and fissures within it.
WebThe vent is, in itself, a unique consequence of the interaction between hydrothermal fluids and seawater. The vent is created by the precipitation of certain chemicals in the vent fluid. Vents can take on several different … WebHydrothermal vents occur where there is volcanic activity and geothermal heating of the seafloor. They are characterized by buoyant plumes of heated water, the temperature of …

During the DY105-12, 14cruise (R/V DAYANG YIHAO, November 2003) on East Pacific Rise (EPR) 12-13°N, the submarine hydrothermal activity was investigated and the CTD hydrocast was carried out at EPR12°39''N—12°54''N. reclaim tiles north wealdLife 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. … unt flying worm
