This video shows just some of the stunning imagery captured by the high-definition cameras on the Little Hercules remotely operated vehicle (ROV) on June 30, 2010, during the vehicle's second dive down to Kawio Barat volcano, in Indonesian waters. 

During the descent to the location where plumes were discovered the previous day, the ROV encountered white plumes of warm, sulphur-rich water and followed the plumes to their vent source amongst volcanic rock. The rocks surrounding the vents were covered in white sulphur. Close-up images of both yellow and black "frozen" flows of sulphur are also seen in the video; the color indicates the temperature at which molten sulphur was extruded. 

Shrimp and limpets live among the strands of yellow and black sulphur, and feed on the bacteria that grow near the vents.

The latter portion of the video shows another hydrothermal area on Kawio Barat with a very dense population of stalked barnacles! These vent barnacles have filaments of bacteria growing on their feeding appendages; they retract the appendages to feed on the filaments. 

A sulfide chimney emitting hot water among a field of chimneys and barnacles as far as the eye could see are also visible; these chimneys are built from mineral precipitation when the hot vent fluids mix with seawater.
