The yellow pillars are vertical egg cases laid by Neptunea snails at Pinnacle, near Southern Hydrate Ridge, providing cover for rockfish and crabs. Credit: NSF-OOI/UW/CSSF, Dive R2228, V22

A crevice opened up in the sediment and carbonate rock near Southern Hydrate Ridge (likely due to methane gas and hydrate buildup beneath the surface) is filled with white, sulfide oxidizing bacterial mats. Credit: NSF-OOI/UW/CSSF, Dive R2228, V22

While replacing a seismometer at Southern Hydrate Ridge, we observed a hagfish (at right) and a large number of brittle stars (ophiuroids) carpeting the sediment. The object on the right is the "undervator" that latches beneath the ROV to bring instruments and materials to the seafloor and back. Credit: NSF-OOI/UW/CSSF, Dive R2225, V22

A pink anemone grows on a discarded tarp or bag at Southern Hydrate Ridge. Solid attachment points can be hard to find in the deep sea, so human-made objects (instruments, cables, or even trash) often attract encrusting animals. Credit: NSF-OOI/UW/CSSF, Dive R2221, V22

An instrument, known as the Universal Fluid Obtainer (UFO), used by PI Dr. Rika Anderson (Carleton College) to collect and filter water from a diffuse flow vent in the International District at Axial Seamount. The vent itself is surrounded by blue ciliates. Credit: UW/NSF-OOI/CSSF, Dive R2213, V22.

Bryozoans, a type of filter-feeding, moss-like animal, are a common type of biofouling organism found on the Shallow Profiler components, like this electrical junction (aka FACT cage) at Axial Base. Credit: UW/NSF-OOI/CSSF, Dive R2209, V22.

Babysitter snails (Neptunea) lay their eggs in spiral columns that form a habitat for other animals, like these shrimp. This field of egg cases are on top of a carbonate outcrop called Pinnacle which is to the west of Southern Hydrate Ridge. Credit: UW/NSF-OOI/CSSF, Dive R2228, V22.
