Einsteins Grotto 2018

Einsteins' Grotto, the active methane seep first visited by the UW in 2010, continues to surprise us – this year, multiple bubble streams were issuing from the pit and exposed methane hydrate was documented in the sides of the wall. Credit: UW/NSF-OOI/WHOI, V18.

Hagfish Investigate Flow Meters at SHR

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.

Nascent Collapse Forming

A nascent collapse zone formed since last year. ROPOS found this site by seeing bubble plumes >100 m off bottom with their sonar. Following the plume to the seafloor led us to this collapse zone. Credit: NSF-OOI/UW/ISS, V15.

Changing Face of Enstein’s Grotto

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.

Dive R1754 Highlights Southern Hydrate Ridge

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.
