A digital still camera, mass spectrometer, and fluid and microbial DNA sampler installed at the El Gordo hydrothermal chimney, International District Hydrothermal Field, Axial Seamount.

Collapse basins marked by columns, drainback features, and arches are common features in areas where lava ponded and spilled rapidly over the seafloor in 2011.

A huge rattail, ~ 5 feet in length, swims slowly in front of the ROV ROPOS near the International District Hydrothermal Field at a depth of 5000 ft beneath the ocean's surface. This area has a higher abundance of these fish than observed elsewhere in the caldera, perhaps because of the larger size of the vent field and hence food source.

The ROPOS control room onboard the R/V Thompson is a magical place for many where we get to see parts of the ocean never before seen, and first of their kind operations.

A titanium 'cap' is placed on the top of El Gordo by ROPOS, which focuses the diffuse fluid so that a fluid and microbial DNA sampler can get hydrothermal fluids samples largely undiluted by seawater. The fluid-DNA sampler is in the background. Credit: NSF-OOI/UW/ISS; Dive R1836; V15.

The RO ROPOS holds a 'IGT' gas tight bottle in the orifice of the 280°C chimney called Diva. The high temperature fluids exiting the seafloor at this anhydrite-rich (CaSO4) vent contain the highest carbon dioxide concentrations at Axial Seamount. Credit: NSF-OOI/UW/ISS; Dive R1836; V15.

Pyconogonids are abundant on many sulfide structures in the vent fields within the caldera of Axial Seamount. These 8-legged anthropods are commonly found in areas where venting has stopped, leaving variably oxidized edificies. Here, they are associated with snails an a small scale worm ~ 1 cm; in length.

An Osmotic fluid sampler is installed in a small diffuse flow site hosting abundant tubeworms, limpets, and palm worms in the ASHES hydrothermal fluid. When recovered next year, the fluids this sampler host will provide information on how vent fluid chemistry changes over time.

A lush community of vibrant red tube worms grows on a 1 m tall black smoker chimney in the ASHES hydrothermal field. The tube worms, which are hosted in white housings about the diameter of your small finger, are intergrown with brown palm worms.Credit: NSF-OOI/UW/CSSF; Dive R1835; V15.

A new high definition camera was installed at the hydrothermal vent called 'Mushroom' in the ASHES hydrothermal field atop Axial Volcano. The camera, built by the UW Applied Physics Lab, was tested today and streamed live HD imagery >300 miles back to shore from a water depth of >5000 m. Credit: Credit: NSF-OOI/UW/ISS; Dive R1835; V15.
