The ROCLS cable drum is unlatched on the seafloor at the base of Axial Seamount near PN3A at a depth of 2600 m. The cable, once plugged into a junction box and Primary Node, will power and communicate with ~2600 m-tall (8500 ft) instrumented moorings, as well as seafloor instruments.

The anhydrite chimney 'Diva' visited with the ROV ROPOS during the VISIONS'14 program. This is an extremely CO2-rich vent with temperatures measured at 294°C (561°F) in July.

During Dive R1273, the 271°C venting orifice was visited at Escargot and a gas-tight fluid sample was taken. The srtucture is named after its morphology, which clearly resembles a snail. Photo Credit: NSF-OOI/UW/CSSF; Dive R1713; V14.

The CTD (Conductivity-Temperature-Depth sensor) is deployed into the ocean. All of the Niskin bottles are held open before deployment and are closed individually to collect water samples at different depths as the CTD carousel rises through the water column.  Photo credit: John Wonderly, Clallam Bay School, V14.

The Conductivity, Temperature and Depth (CTD) probe lies within a large carousel of Niskin water bottles.  The carousel is lowered to the seafloor while the CTD makes measurements.  On the 'ride' up, a person on deck triggers the water bottles to close (one at a time) to collect a water sample at different depths.  Photo credit: Mitch Elend, University of Washinton, V14.
