"You can go for hundreds of meters along the and see nothing. But then you’ll get to a and it will be a garden of exotic creatures. The vents are like the . The seawater percolates down through cracks caused by earthquakes, and then it comes up through these underwater chimneys. There are lots of ores there like copper, gold, silver, and s. There’s so much life there, and it’s very different from what we’re used to seeing. Whenever scientists go down, we almost always find new creatures."

"and their were discovered in 1977. While the hot-water springs were predicted to occur at s, no one expected to find them colonized by exotic invertebrate faunas. Accustomed to a view of the deep sea as a food-limited environment, the puzzle of how lush communities could be maintained provoked biologists into a flurry of research activity. ... As field programs multiplied and more vent communities were discovered, biogeographic patterns in the distribution of faunas became apparent and ecological issues of requirements, , and began to be addressed. associated with diverse settings, from and s to . Massive bacterial blooms triggered by the release of nutrients during a volcanic eruption, rapid colonization of new vents by invertebrates, and burial of extant vent communities by lava flows demonstrate the dynamic nature of hydrothermal systems. Perhaps the most provocative consequence of the discovery of seafloor hydrothermal vents is the ."

"in the late 1970s led to the discovery of at s. More recently, sulphide deposits containing . In addition to metal-rich ores, hydrothermal vents host ecosystems based on . Although there has been considerable effort to study the biology and ecology of vent systems in the decades since these systems were first discovered, there has been limited attention paid to conservation issues. Three priority recommendations for conservation science at hydrothermal vent settings are identified here: (i) determine the natural conservation units for key species with differing life histories; (ii) identify a set of first principles for the design of preservation reference areas and conservation areas; (iii) develop and test methods for effective mitigation and restoration to enhance the recovery of biodiversity in sulphide systems that may be subject to open-cut mining."

"ecosystems have stimulated decades of and hold promise of mineral and genetic resources that also serve societal needs. Some endemic taxa thrive only in vent environments, and vent-associated organisms are adapted to a variety of natural disturbances, from tidal variations to earthquakes and volcanic eruptions. In this paper, physicochemical and biological impacts of a range of human activities at vents are considered. , albeit at a local scale, based on our current understanding of ecological responses to disturbance. Natural recovery from a single mining event depends on immigration and larval recruitment and colonization; understanding processes and dynamics influencing life-history stages may be a key to effective minimization and mitigation of mining impacts. Cumulative impacts on of several mining projects in a single region, without proper management, include possible species extinctions and shifts in community structure and function."
