Hydrothermal vents are distributed along the Earth's plate boundaries, although they may also be found at intra-plate locations such as hotspot volcanoes. As of 2009 there were approximately 500 known active submarine hydrothermal vent fields, with about half visually observed at the seafloor and the other half suspected from water column ...
Lost City and other hydrothermal vent systems support vastly different lifeforms due to Lost City's unique chemistry. A variety of microorganisms live in, on, and around the vents. Methanosarcinales-like archaea form thick biofilms inside the vents where they subsist on hydrogen and methane; bacteria related to the Bacillota also live inside ...
Loki's Castle is a field of five active hydrothermal vents in the mid-Atlantic Ocean, located at 73 degrees north on the Mid-Atlantic Ridge between Iceland and Svalbard at a depth of 2,352 metres (7,717 ft). [1] [2] [3] When they were discovered in mid-July 2008, they were the most northerly black smoker vents known to science. [4]
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 ...
The Beebe Hydrothermal Vent Field (abbreviated BVF, also known as the Piccard Vent Field) is the world's deepest known hydrothermal vent site and is located just south of Grand Cayman in the Caribbean, on the north side of the Mid-Cayman Spreading Centre in the Cayman Trough. [1]
Under these regulations, activities that pose any harm to vent systems is prohibited. The hydrothermal vent fields—Salty Dawg, High Rise, Main Endeavour, and Mothra—were divided up into four different subfields after being mapped in 1991. A fifth vent field, Sasquatch, was later discovered in 2000 and is situated just north of Salty Dawg. [29]
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 Kairei vent field is one of the few known locations of the Sea Pangolin, threatened by deep sea mining. [5] It is also a site associated with Gigantopelta aegis and Alviniconcha strummeri gastropods. [6] It is the site of discovery of Rimicaris kairei, belonging to the family of hydrothermal shrimp found at many sites in the Atlantic Ocean. [7]
