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.

On launching, the CAT jumped the tool sled and fell to the seafloor. The broadband was deployed for follow-on installation, and the Mosquito and Osmo sampler were installed. Push cores were taken and a brief survey found the CAT. It was recovered and is expected to be fine as they are normally deployed by free falling. Video credit: NSF-OOI/UW/CSSF; Dive R1772; V14.

The ROV transited NW to the location of the broadband caisson, and on the way a carbonate rock sample was recovered. Upon reaching the broadband caisson, the ROPOS turned south on a 190° heading for a 500 m long survey of the 10 km cable route. Video credit: NSF-OOI/UW/CSSF; Dive R1765; V14.

The locations for installation of the LV01B and LJ01B junction boxes were surveyed in, and pallet drop site for the Dependable was determined. The dive ended with a survey of all three extension cable routes for the seismometers. One spectacular find, was the discovery of a nursery for Neptunea snails that form yellow egg stalks.
