The Ashadze hydrothermal field (13°N on the Mid-Atlantic Ridge, elevation -4200 m) was the deepest known high-temperature hydrothermal field until 2010, when a hydrothermal plume emanating from the Beebe [102] site (, elevation -5000 m) was detected by a group of scientists from NASA Jet Propulsion Laboratory and Woods Hole Oceanographic ...
Seven large hydrothermal fields have been discovered within the waters of the Azores: Lucky Strike Hydrothermal Field (discovered in 1992), is the largest known hydrothermal field within the archipelago, with 21 active vents spread over 150 square kilometres (58 sq mi). The hydrothermal fluids reach temperatures of 330 °C (626 °F) (very close ...
This incredible active hydrothermal vent was imaged for the first time during the Marianas expedition. It was 30 meters high and gushing high-temperature fluid full of metal particulates. This vent was home to many different species, including Chorocaris shrimp, Munidopsis squat lobsters, Austinograea crabs, limpets, mussels, and snails. Date
The hydrothermal plume nicknamed "Piccard" was detected in 2010, [3] and the Beebe site was confirmed later that year. [1] The combined depth and vent fluid temperature make it a popular site for studying aqueous thermodynamics, high-pressure biology, and geochemistry.
Hydrothermal circulation in the oceans is the passage of the water through mid-oceanic ridge systems.. The term includes both the circulation of the well-known, high-temperature vent waters near the ridge crests, and the much-lower-temperature, diffuse flow of water through sediments and buried basalts further from the ridge crests.

The environment of the Endeavour Hydrothermal Vent field experiences extreme temperature ranges of 300 °C all the way down to 2 °C from even just a few metres away. Stressors like elevated acidity, carbon dioxide (CO 2), sulfide, anoxia, and metal ions are just a few examples of the extreme conditions in fluid vents. The hydrothermal vents ...
The temperature and composition of Axial Seamount's hydrothermal vents changes over time, but always maintains a roughly common identity, as do the vents' individual microbial communities. [19] Vents generally have a lower pH than the surrounding fluid, and are acidic and alkaline as a result. The temperature of the magma feeding the system is ...
The Rainbow hydrothermal vent field is a system of ultramafic-hosted hydrothermal vents located at 36°14'N on the Mid-Atlantic Ridge (MAR). It was discovered in 1994 from temperature readings of ten high-temperature black smokers at a depth of approximately 2.3 kilometres (1.4 mi), where fluids can exceed 365 °C (689 °F).
