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.

The caisson (the hole in the sediment at center) was excavated using a suction tube attached to the ROV during a previous expedition. Credit: UW/NSF-OOI//CSSF, ROPOS ROPOS Dive R1750, V14.

Clams at Southern Hydrate Ridge host symbiotic microbes. This colony is perched at the ledge above Einstein's Grotto, which in 2013 was actively venting. Ccredit: UW/NSF-OOI/CSSF; ROPOS Dive R1750; V14.
