ROCLS gently sets down on the seafloor in preparation for deployment at an ~ 5 km long extension cable to the Central Caldera site at the summit of Axial Seamount. Over 15,000 feet of cable is hosted on the drum. Credit: NSF-OOI/UW/CSSF; V14.

The Remotely Operated Cable Laying System (ROCLS) shown deployed at the summit of Axial Seamount near Primary Node 3B (water depth ~ 5000 ft). The drum holds ~ 2000 ft of cable that will soon be deployed. Once a small section of the cable is secured to the secondary node (in distance, on left), ROPOS will latch into the top of ROCLS and "fly" through the water column, deploying cable underneath it as it travels.

Pressure data were collected in real-time from 8000 ft beneath the ocean's surface to the ship, through a junction box on the seafloor powered by the ROV and providing communications from the seafloor to the ship through its fiber-optic cable. This was the first end-to-end test of the junction boxes, extension cables, and instruments.

it is always a good day at sea when the waters are calm and the skies are blue.

View of the front porch of ROPOS showing a connection from the RSN Interface Box on ROPOS to an extension cable that is 1800 feet in length connected to a Secondary Junction Box (another power and communications outlet on the seafloor). The connector with the orange handle is "wet-mateable", meaning that it can be unplugged and plugged in on the seafloor.  When disconnected, it is placed in a parking position to keep the connectors clean and safe (stand with red handle to the right).   Photo credit: NSF-OOI/UW/CSSF

Deployed at the base of Axial Seamount, this secondary node was used as an anchor during the deployment of 600 m of extension cable and during testing while ROPOS dowloaded data from a pressure sensor and current meter. (credit: NSF-OOI/UW/CSSF)
