The temperature-resistivity instrument measures, in real-time, the temperature of black smoker fluids (>400°C) and the resistivity of the fluids as a proxy for chlorinity. Vents at Axial Seamount are boiling, producing fluids that are very low in chloride content (salts). Boiling is an important processes because it enhances precipitation of precious metals in seafloor black smokers.

Short-period seismometers provide real-time information on earthquakes at mid-ocean ridges. In 2003, an array of seismometers was deployed on the Endeavour Segment of the Juan de Fuca Ridge, north of Axial Seamount. The one shown here, was deployed inside a borehole in a pillow basalt in the Mothra Hydrothermal Field, providing better coupling to the seafloor. This project was funded by the W.M. Keck Foundation.

'Osmo' samplers draw hydrothermal fluids into small capillary-like tubing and allow long-term sampling of diffuse and black smoker hydrothermal fluids, as well as fluids from methane seeps. Osmo samplers in this image (white canisters) are attached in an in situ 'microbial' incubator deployed inside the walls of a black smoker chimney called Gremlin. The osmo samplers allowed collection of vent fluids for 1-year, while the microbial incubator collected hundreds of temperature measurements inside the wall of the black smoker. Novel microbes colonized mineral wafers and new sulfide precipitates inside 4 discrete chambers within the incubator. This experiment, led by D. Kelley, University of Washington, was designed to look at the upper temperature limit of life. Osmo samplers will be deployed at the ASHES hydrothermal field and at the summit of Southern Hydrate Ridge during the VISIONS'13 expedition.

The Offshore Endurance site at 600 m water depth will host two cabled moorings and a Benthic Experiment Platform with numerous physical, chemical and biological sensors, as well as a digital still camera.
The Offshore Endurance site at 600 m water depth will host two cabled moorings and a Benthic Experiment Platform with numerous physical, chemical and biological sensors, as well as a digital still camera.
The Benthic Experiment Package (BEP) is composed of a hazard-resistant frame (shown here), the inside of which hosts an UW-APL-designed Low Power communications housing, and a variety of sensors to measure oceanographic properties that include acidity (pH), carbon dioxide, salinity and oxygen concentrations, and currents. A hydrophone that will be mounted outside of the frame will be used to detect sounds in the ocean. The BEP is scheduled for installation in 2014 at the Endurance Offshore site that is part of the Endurance Array's Newport Line. This site is also the location of one of the RSN Primary Nodes, which is the power and data hub for the BEP Low-Power Junction Box, which is in turn the power and data hub for a variety of instrument platforms.

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.

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.

This resistivity-temperature probe was deployed in the 270°C hydrothermal vent called 'Escargot' at the summit of Axial Volcano in 2013. Resistivity is an analoge for chlorinity or "saltiness' of the hydrothermal fluids. Boiling is common in these venting environments, governing gas concentrations, metal deposition, and perhaps life. A cabled version will be installed in 2014 providing real-time 24/7 data. ROPOS dive #1618, VISIONS '13, Leg 3. Photo credit: NSF-OOI/UW/CSSF.

Samples of fresh basalt were collected from Axial Seamount's caldera floor.  When fresh, the outer surface of the rock is glassy due to the very rapid cooling and crystallization that occurs when the hot lava comes in contact with the 2oC seawater.  This glass - known as obsidian - is very sharp and crumbles easily.

The summit of this hydrothermal chimney, called 'Eascargot', has a striking resemblance to a snail. A 270°C actively venting site (two small white chimneys mid structure) will host a cabled temperature-resistivity sensor there in 2014. This sensor will provide real-time data on the fluid chemistry (chlorinity) -temperature relationships inside the vent. The instrument was designed by Marv Lilley, University of Washington.

This short-period seismometer was deployed on a flat sheet flow ~ 1.3 km east of the ASHES hydrothermal field in 2013. The black ball in the yellow circle shows that it is perfectly level, helping to insure that the highest quality data comes off of this network. Axial Volcano is likely to be quite seismically active and we are anxious to get the real-time data on shore next year. This will help us understand magma and fluid migration in the subsurface of the volcano...and eventually these data may help us predict an eruption. Several earthquakes were detected in real-time during testing of these seismometers in 2013. Credit: UW/NSF-OOI/CSSF, ROPOS Dive R1635; V13.

A resistivity-temperature probe, developed by Dr. Marv Lilley at the University of Washington, was deployed into a 270°C actively venting orifice on the chimney called Escargot. Resistivity is an analogue for chlorinity. Some of the vents in the International District are boiling, causing release of very gas-rich, low-salinity fluids. This instrument, recovered on ROPOS dive 1638, was deployed on a small ledge on the structure a few weeks previously with power provided by batteries in the titanium housing. The orange-white taped cable leads to the wand that is inserted into the chimney (not shown in this image). The white, feathery material on the outside of the chimney is filamentous bacteria, supported by low-temperature diffuse fluids that waft up the side of the chimney. Photo credit: NSF-OOI/UW/CSSF

The Diva hydrothermal vent, is a 277°C small, fragile anhydrite (CaSO4) structure in the International District vent field on Axial Volcano. The chimney is of interest because it has the highest carbon dioxide concentrations of any of the chimneys within the Axial caldera. In 2014, it will host an instrument developed by Dr. Bill Seyfried, University of Minnesota,  that will provide real-time streaming data on acidity, hydrogen sulfide, hydrogen and temperature of the vent fluids.

Diagram of Axial cables and instruments
The summit of Axial Volcano will host myriad geophysical, chemical and biological instruments connected in real-time to the Internet via an array of junction boxes and extension cables. During the VISIONS'13 Expedition, three subnets were completed at this site (highlighted in blue). They include: 1) a medium-powered J-box MJ03B in the ASHES hydrothermal field, which is connected to two short-period seismometers; 2) an HD camera also in the ASHES hydrothermal field; and 3) a medium powered J-box MJ03E connected to two short-period seismometers. Over 20 km of extension cables, with lengths up to ~ 5 km, were successfully installed in 2013 using the ROV ROPOS. All extension cables and subnets were fully tested and are functional, awaiting to be connected to Primary Node PN3B. The remaining infrastructure will be deployed in during VISIONS'14, next year.

This medium powered junction-box (MJ03B) in the ASHES hydrothermal field was installed during the VISIONS'13 expedition. The titanium cylinder inside the frame hosts the power converters, data ports, and communication capabilities to shore via the Primary Nodes. A 4.3 km cable extends from this J-Box across the caldera to PN3B, where it awaits future connection. MJ03B was installed as a 'subnet' during VISIONS'13 - two short-period seismometers are now connected to it via a 50 m and 1.2 km extension cable, respectively. A also host a cabled 3D thermistor array (a test instrument is shown in this image - triangular shaped frame with blue cables) was also deployed for testing. MJ03B, and all cables and connected sensors were fully tested during VISIONS'13, and are fully functional. During the several hour test period, several earthquakes were detected.

An ODI hybrid wet-mate connector provides > 1 Gbs video transmission capabilities and power to the RSN-OOI-NSF high definition camera that was deployed during the VISIONS'13 Expedition. The wetmate connectors allow an ROV to connect and disconnect infrastructure underwater without having to recover the equipment. The camera shown here is at a water depth of ~ 5000 ft at the summit of Axial Seamount. The orange extension cable (on right of camera) was powered up by the ROV ROPOS through an ~ 4 km extension cable that traverses eastward across the caldera at Axial Seamount. Live video video from the HD camera was streamed over the Internet for several hours during testing of the camera. In 2014, the extension cable will be connected to Primary Node 3B for 365 day access. The camera was installed at the base of the hydrothermal chimney called Mushroom in the ASHES hydrothermal field.
