This bathymetric map of ASHES Hydrothermal Field shows the location of many of the black smoker chimneys that dot this site. The chimney Inferno rises 4 m (~ 12 feet) above the surrounding seafloor and is ~ 11 meters from its neighbor called Mushroom. Colleagues from NOAA-PMEL have worked at this site for two decades, monitoring changes in the chimneys and fluid chemistry.
