During the VISIONS'13 expedition, low frequency hydrophones, coupled with broadband seismometers, will be deployed at the base of the Cascadia Margin (Slope Base), and at the base of and summit of Axial Volcano.

This thermistor array, designed by Giora Proskurwoski, a Project Scientist as part of the UW cabled observatory team, will allow 3-D measurements to be made in diffuse flow sites over time, with real-time transmission of the data to shore via the cable. Temperature, in part, governs where animals and microbes thrive, expire, and evolve at vent sites. Photo by Mary Levin, UW.

The Mushroom hydrothermal chimney at the ASHES vent field, hosts dense communities of limpets, a variety of worms (palm, tube, scale, sulfide), and filamentous bacteria. The chimney rises ~ 4 m above the seafloor. This mosaic was compiled by M. Elend, University of Washington from several high definition images. Credti: M. Elend, University of Washington.

During the VISIONS'13 expedition, the R/V Thompson and the ROV ROPOS will be critical to successful deployments and testing of extension cables on the seafloor as part of  NSF's Ocean Observatories Initiative regional cabled observatory.

A variety of geophysical sensors will be deployed at the base of Axial Seamount to monitor seismic events on the Juan de Fuca plate.

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.
