R1720 Dive Highlights Central Caldera Cable Lay

Loading the player...

PN3B-Central Caldera Cable Lay - RS03W9: The goal of this dive was to install nearly 15,000 ft of extension cable (RS03W9) from Primary Node PN3B to the Central Caldera Site that would connect the geophysical array here.However, 250 m (~800 ft) into the lay hydraulic power was lost and ROCLS dropped to the seafloor (ROCLS was designed to do this for vehicle safety). ROPOS ascended to repair the failure and prepare for an inspection and recovery dive - which was successful and the cable was fine. Video credit: NSF-OOI/UW/CSSF; Dive R1720; V14. (01:34)
