Deployment of the 200m platform of the Endurance Oregon Offshore two-legged mooring, which will eventually host a winched shallow profiler and bioacoustic sonar instruments. Two mooring lines with seafloor anchors are attached to the sides of the platform (rather than the usual single mooring line) to add stability to the platform so it can act as the profiler base.

A cockatoo squid (likely Taonius borealis) encountered at 585 meters depth during a site survey between the 2-legged mooring EOM leg anchor and the low-voltage node LV01C at Oregon Offshore. The squid was red when we first encountered it, and then turned transparent as the ROV ROPOS took video. Credit: UW/NSF-OOI/CSSF, rOPOS Dive R1752, V14.

ROPOS lowering the Slope Base seismometer into the previously excavated caisson. After deployment, the caisson was filled with glass beads to couple the seismometer to the seafloor. The attached hydrophone tripod is being held in the starboard arm of ROPOS, and was deployed alongside. Photo Credit: NSF-OOI/UW/CSSF, Dive R1751, VISIONS14

A deep-sea octopus (possibly a Muusoctopus), clinging to the leg of the medium power junction box MJ01A at Slope Base. It may be brooding eggs, and they can guard their eggs for over four years, longer than any known animal. Credit: UW/NSF-OOI/CSSF, ROPOS Dive R1751, V14.
