[2] The vent field lies 2,250 metres (7,380 ft) below sea level on the northern Endeavour segment of the Juan de Fuca Ridge.

In order to best grasp the scale of the EHV region, autonomous vehicles have been deployed to survey the areas and cable systems have been put in place so that better management practices can be taken.

The protected area for the Endeavour Hydrothermal Vents is located on the ridge of the Juan de Fuca plate, and the established zone is 100 km2 (39 sq mi).

The Endeavour section of the Juan de Fuca Ridge is approximately 90 km long and spreads at 6 cm per year.

[4] These sites are: Bastille, Crypto, Dante, Dudley, Easter Island, Grotto, Hulk, Lobo, MilliQ, Peanut, Puffer, Salut, Smoke & Mirrors, Sully, TP, and Quebec.

[10] Tectonic events like diking, such as those detected by SOSUS in 1999, caused vent geochemistry to change drastically throughout the field.

[13]Heat of the Endeavour Hydrothermal Vents is supplied by the conductive cooling of the Earth's crust along the axis and from magmatic sources beneath the field.

Seawater seeps diffusively or through cracks into the Earth's crust, warms at depth, and then rises back up after it is heated at venting orifices.

Fluids from deep ocean vents have a diverse spectrum of chemical compositions and are frequently enriched in metal sulfides, such as those from iron, copper, calcium, silicon, and zinc as well as metalloids.

Among the major sulphide and sulphate minerals preserved at vent sites, barite (BaSO 4) is unique in that precipitation requires the direct mixing of Ba-rich hydrothermal fluid with sulfate-rich seawater.

Barite crystals retain geochemical fingerprints associated with formation conditions due to their extremely low solubility.

According to their thermal, particle, and chemical anomalies, vent plumes rise 50 to 350 metres above the seafloor to a level of neutral buoyancy.

Stressors like elevated acidity, carbon dioxide (CO2), sulfide, anoxia, and metal ions are just a few examples of the extreme conditions in fluid vents.

[18] Hydrothermal vents are located at mid-ocean ridges, where an abundance of life is present, providing high biodiversity and productivity.

[19] Researchers have identified 12 endemic species to the Endeavour Segment of the Juan de Fuca Ridge that do not exist anywhere else in the world including the sea spider (Sericosura venticola).

[20] Many marine mammals, such as Dall's porpoise, sperm whales, Pacific white-sided dolphin, leatherback sea turtle, and northern elephant seal have also been spotted in the waters where vent fields are located.

On the other hand, Salty Dawg and High Rise are labelled as having the highest precaution, limiting the number of observations and activities that can be done in the fields.

[30] and other autonomous underwater vehicles (AUV) revealed that there were 572 hydrothermal sulfide chimneys total, of which only 47 are known to be currently active within the 14-kilometre (8.7 mi) segment of the ridge.

[12] During the early 2000s, due to the geographical instabilities, many consultations and workshops were held to discuss and process the designation of the Endeavour Hydrothermal Vent system (EHV) as a MPA.

[6] Since 1987, Canada has been utilizing their cabled observatory called North Pacific Time-Series Underwater Experiment (NEPTUNE).
