The OOI Regional Scale Nodes cabled observatory is currently under construction. Nodes with arrays of instruments will be placed at Axial Seamount and Hydrate Ridge. Future node sites are also indicated.
This full-sized Junction Box frame was successfully deployed and recovered in the International District Hydrothermal Field at Axial Seamount using the ROV ROPOS during the August 2011 VISIONS '11 expedition. During the VISIONS'13 cruise two fully built out medium-power J-Boxes will be deployed here that will provide power and communications to extension cables and sensors deployed at the vent sites. The sensors will include a digital still camera, mass spectrometer, fluid and DNA samplers, bottom pressure and tilt sensor, a temperature-chlorinity probe to measure boiling fluids exiting the vents, and a short-period seismometer.

Mitch Elend works to stitch images of the seafloor at Southern Hydrate Ridge together into a photo mosaic in real time. OOI scientists will use the final mosaic to plan the instrument layout for the cabled observatory component of the OOI. (photo by Allison Fundis)
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.
