Hot Vent Waters

On 30 September 2010, we installed a BARS (Benthic & Resistivity Sensors) device at the Grotto hydrothermal vent in the Endeavour Ridge deep-sea rift valley. Watch as ROPOS lifts the device from the nearby instrument platform, flies with it to the vent site, then inserts the probe into a black smoker vent opening.

The BARS recorded temperatures near the vent at 4°C, and over 329°C inside the vent. Incredibly, tubeworms and other creatures flourish on hydrothermal vents due to unique adaptations allowing them to withstand such extreme temperature variations.
