Deployment of short-period seismometers on the seafloor requires special consideration in terms of the sensors being level. Here, a special platform hosting the seismometer is being leveled by ROPOS through turning of adjustment bolts on the legs. These instruments will provide important real-time data on seismic activity inside the volcano, and associated with microfracturing events around the plumbing system for hydrothermal vents.

Safety is a priority aboard the R/V Thompson, and part of that is learing to rapidly put on an emergency life suit.

First earthquake data from Eastern Caldera subnet. Seen here are two sets of patterns, three panels from each seismometer. VISIONS '13, Leg 3.

Many of the collapse areas have lava pillars that support remnants of the roof that originally covered a lava pond. Credit: UW/NSF-OOI/CSSF; ROPOS Dive R1608; V13.

A cable that will link an instrument to a Secondary Node is buoyant enough so that it easily spans across a large collapse area without danger of abrasion. (VISIONS '13 Dive R-1611) Photo credit:  OOI-NSF/UW/CSSF

The testing box on ROPOS was used to plug into a 4356 m (14291 ft!) long extension cable (RS03W7) that starts at  Primary Node 3B on the northern side of the caldera, runs clear across the caldera, and ends just west of the black smokers in a zone of safety. It will provide power and communication to two short-period seismometers and a three dimensional temperature array deployed in a diffuse flow site at the base of the chimney called Mushroom.

This high resolution bathymetric map of the ASHES hydrothermal field shows the location of small, ~ 4 m tall, actively venting sulfide structures. The field is located near the steep western caldera wall. The field is likely fed by fluids circulating up along faults associated with this wall.

A young smoker near the base of the suflide edifice called 'Mushroom' emits particle-poor, shimmering water at temperatures  >100oC.  Tube worms, palm worms and limpets bathe in diffusely flowing fluids that vent out of the porous chimney walls and mix with the surrounding, nearly freezing seawater. A high definition camera will be installed at this site providing real-time live imagery in 2014. (VISIONS '13 Dive R-1614) Photo credit:  OOI-NSF/UW/CSSF

Cooling lava takes on different shapes, depending on the temperature and vigor of the flow.  Here, lava lobes, sheet flow and jumbled flow types fill the frame near to the Ashes vent site on Axial. (VISIONS '13 Dive R-1613) Photo credit:  OOI-NSF/UW/CSSF
