The ROV ROPOS gently flew into a small collapse basin marked by pillars, arches and isolated columns of basalt. These areas form as lava drains out from deep lava pools. The surface of the lava lake or channel very rapidly cools as it interacts with near freezing seawater. As the lava drains out, the roof is not strong enough to maintain its weight, and collapses into a pile of talus. Credit: UW/NSF-OOI/CSSF; V11.

This sulfide chimney, known as Mushroom, rises ~ 4 m (12 ft) above the seafloor. It is located in the ASHES Vent Field and will be the site for deployment of a cabled high definition video camera in 2014 and three-dimensional temperature array, as well as an uncabled vent fluid sampler.

A close up of animals, including palm worms and tubeworms, on the hydrothermal chimney called Mushroom in the ASHES hydrothermal field. The image is a frame grab from video streamed during testing of the OOI-RCA high-definition video camera built by the Applied Physics Lab at the University of Washington. The camera has been at this site for 1 year. Credit: UW/NSF-OOI/ V14.
