A photo from the Jason van screen showing exposed methane hydrate at Einsteins's Grotto - the first time we have observed it there.

Once again the Smokey Caverns (or Taverns as it is also known) has changed remarkably since we visited it with Jason last year. The area is significantly more rugged, marked by large hummocks. An eelpout, sole, clams and orange rock fish dot the landscape. Credit: UW/NSF-OOI/WHOI, V18.

An old Ocean Drilling Program hole serves as a nursery for hagfish and crabs at the summit of Southern Hydrate Ridge. Credit: UW/NSF-OOI/WHOI, V18.

The roughtail skate has a broad nose and sharp scales on the surface. Roughtail skates are around 91 cm in length. This skate was seen at Southern Hydrate Ridge. Credit: UW/NSF-OOI/CSSF; ROPOS Dive 1777; V14.

Neptune Canada’s guide included it in the “sea anemone” category because of similarity, but it belongs to another order: Corallimorpharia. This Corallimorph anemone was spotted on the seafloor at Southern Hydrate Ridge at a depth of 774 m.

The vibrant Neptunea nursery that was covered in bright yellow egg stalks topped with Neptunea snails is not longer active. Only casings and empty shells remain. Credit: UW/OOI-NSF/WHOI; J2-981; V17.

The Pinnacle, on the west of the main methane seep sites at Southern Hydrate Ridge, is a 60 m tall, rugged carbonate edifice teaming with life - dominated by high densities of soft corals, hagfish, and small squat lobsters that hide in small cavities. Credit: NSF-OOI/UW/ISS, V15.

The Neptunea nursery in 2015 was devoid of tending snails on top of the egg stalks. Recovery of the stalks showed that the eggs are still viable. Credit: NSF-OOI/UW/ISS, Dive R1845, V15.

Deb brings in a recovered carbonate cobble with egg casings of Neptunea snails from Southern Hydrate Ridge. The eggs can take up to 1 year to hatch. Credit: Mitch Elend, University of Washington, V15.

A before and after image of the fantail on the R/V Thompson the day we left port (August 26) and came back (September 10). In between these two port calls, we came back into Newport and loaded another complete set of gear to install on the seafloor. Photo Credit: Mitch Elend, University of Washington, V14.

The manipulator arm of the ROV ROPOS reaches for a small block of methane hydrate wedged against a small rampart and nearly vertical wall within a large collapsed area at the summit of Southern Hydrate Ridge. Several minutes after sampling this site with the ROV, a continuous jet of methane bubbles issued from the large opening to the right of the hydrate sample. The methane hydrate is translucent, very clean and is reminscent of quartz with a conchoidal-like fracture pattern and is partially encased in a thin skin of sediment.

Mola mola, a sunfish, are the heaviest known bony fish. They can weigh ~2000 lbs - they mainly eat jellyfish. Credit: Billy Medwedeff, University of Washington; V14.

Soft corals dot the rough carbonate surfaces of the ~ 60 m-tall limestone monolith west of the active seeps at Southern Hydrate Ridge. Credit: UW/NSF-OOI/CSSF; ROPOS Dive R1779; V14.

A broadband seismometer installed inside a buried cassion at Southern Hydrate Ridge by the ROV ROPOS. A follow-on dive will fill the caisson with silica beads, which dampens noise. The broadband and low frequency hydrophone is installed here to detect both large and small earthquakes that may impact the release of methane gas into the hydrosphere.

An ~60 m tall carbonate pinnacle, west of the active seep site at Southern Hydrate Ridge, hosts abundant soft pink corals and is a rich habitat for squat lobsters, clams, a variety of fish, and crabs. Credit: UW/NSF-OOI/CSSF; Dive R1779; V14.
