This 90 cm, ~100 lbs. chimney was collected from the base of the El Guapo sulfide chimney at the International District Hydrothermal Vent Field on Axial Seamount (ROPOS Dive 1617).  (Photo by Leslie Sautter)

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.

This relatively small (<1 m) inactive chimney recently toppled over, becoming an excellent sample for collection. (ROPOS Dive #1617, VISIONS '13, Leg 3) Photo credit:  OOI-NSF/UW/CSSF

Owen Coyle is a Biological Oceanography Ph.D. candidate at the University of WAshington.  He is participating on all four legs of the VISIONS '13 expedition and is the TA for the UW Sea-Going Research & Discovery course.

Owen has troubles staying awake during the long hours of standing (sitting?) watch.  Even Coca-Cola doesn't do the trick.

Students Brendan Philip and and Cody Turner work with Professor Julie Nelson in the computer lab.  They are monitoring the temperature and salinity profiles created during the downcast of the CTD to determine the depths for triggering Niskin bottles for seawater collections.

An at-sea tradition is to send styrofoam cups and wig-heads (usually embellished with stylistic artwork) down to the depths so that the overwhelming pressure in the deep sea compresses the objects into miniature versions. (Photo by Leslie Sautter)

Part of the work required to properly install a seismometer on the seafloor is to ensure that the instrument is level. The yellow disk, shown here, is placed on the seismometer by ROPOS. The legs of the seismometer platform are then adjusted until a level reading is achieved. Credit: UW/NSF-OOI/CSSF; ROPOS, Dive 1617, V14. Credit: NSF-OOI/UW/CSSF

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.
