摘要

Discovery of deep-sea hydrothermal vents and associated biological communities on the Galapagos Rift in 1977 was one of the major scientific breakthroughs of the past century, informing our understanding of key issues in the Earth, ocean, and life sciences. More than 100 different vent sites have been found in different ocean basins worldwide since then, and everywhere scientists have looked, new species have been collected. Most recently, scientists were surprised to find that water-rock interactions during hydrothermal circulation at the least volcanically active mid-ocean ridges could give rise to the synthesis of organic compounds in vent fluids that may reveal insight into the origins of life-on Earth and beyond. The August 2011 expedition to the Mid-Cayman Rise, one of Earth's deepest and slowest spreading ridges, followed recent data suggesting there are multiple vent sites present in shallow and deep settings along this ridge axis (German et al., 2010; Connelly etal., 2012).
