Scientists from the UK’s National Oceanography Centre (NOC) have discovered the deepest volcanic vents so far known, 5000 metres below the surface of the Caribbean Sea. The vents are located in the Cayman Trough in the western Caribbean, which reaches a maximum depth of 7,500 metres. Further research will analyse the geology and geochemistry of the vents and the marine life associated with them. NOC geochemist Dough Connelly, Principal Scientist of the expedition, says: ‘We hope our discovery will yield new insights into biogeochemically important elements in one of the most extreme naturally occurring environments on our planet’.

The Cayman Trough expedition, funded by the National Environment Research Council, is based aboard the UK’s new ocean-going research vessel RRS James Cook. For more on the expedition, see our post from August 2008: British scientists to investigate Caribbean deep-sea hydrothermal vents.
