Hagfish investigate flow meters called Mosquitos at methane seeps at Southern Hydrate Ridge (water depth ~800 m). Data from these instruments allow calculation of the flux of fluids into and out of sediments at this gas hydrate site marked by thick bacterial mats and abundant clams. Credit: UW/NSF-OOI/WHOI; V16.
Einstein's Grotto changes rapidly over hours to days. Revisitation of the active seep site today showed that a large sedimentary protrusion at the vent opening had desintegrated and a large and vigorous bubble plume was exiting the orifice.Photo credit: NSF-OOI/UW/CSSF; Dive R1761; V14.
ROPOS Dive R1745 to Southern Hydrate Ridge Summit. The dive verified bubbles coming out of Einstein's Grotto and documented exposed hyrate in the opening. Marker 34 was deployed 50 m south of the junction box LV01B proposed installationa site, inpreparation for the follow-on installation of the 10 km cable to PN1B and deployment of the pallet near the summit of the ridge.
