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.
During decent of ROPOS Dive R1845, a bubble plume was detected on the sonar. The plume was followed to the seafloor, with the source at the Bubble 1 site. This area last year was a gently hollow – now it has a small collapse area and two cavities from which significant methane bubbles are emitted. ROPOS documented this area in detail as a possible installation site if Eisntein's Grotto dies re venting. A quick inspection was done on the digital still camera at Einstein's Grotto and the Neptunea snail nursery was imaged. Credit: NSF-OOI/UW/ISS; V15.
The 'Pinnacle' on the west side of the main methane seep site at Southern Hydrate Ridge, is a >20 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.
