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.
