2005 video clips show the black smoker chimneys at the Vent 1 hydrothermal vent site on the southern Cleft segment of the Juan de Fuca Ridge. The video was obtained during dives T876 and T877 of the MBARI ROV Tiburon in August 2005, funded by NOAA's West Coast and Polar Regions Undersea Research Center. This site has been known to be active since since 1984.
