During subduction of the Juan de Fuca (JdF) Plate beneath the North American Plate, ocean crust and overlying sediments being carried downward heat up, releasing water and other gases into the overlying plate, causing melts to form ~ 50 miles beneath the volcano. Images of the volcanoes are in the USGS public domain. In conrast, Axial Seamount is formed by melts rising from beneath the JdF spreading center that forms the plate boundary between the Pacific Plate and the JdF Plate. Credit. D.

The North American Plate off the coast is bounded by four tectonic plates to thw est (Gorda, Juan de Fuca, Pacific, and Explorer. The plates boundaries are defined by the Cascadia Subduction Zone, the Gorda, Juan de Fuca and Explorer mid-mid ocean ridge spreading centers, and a series of transform faults (also known as fracture zones. Environments closer to shore include the shelf, slope and abyssal plain. A seamount chain marks the movement of the Pacific Plate over a "hot spot" on the Juan de Fuca Ridge, and includes the Cobb Seamount guyot. Credit: D. Kelley, University of Washington.

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 down-looking view of the Mushroom Hydrothermal Vent and adjacent Inferno chimney shows where the high definition video camera, fluid sampler (OSMO), and 3D temperature  (thermistor) sensors will be placed. The HD camera and thermistor array will be cabled. In concert, these instruments will allow characterization of how fluid chemistry and temperature impact biological communities, and how these evolve over time in response to volcanic and seismic events.

The coastal oceans and associated ecosystems off of the Pacific Northwest are strongly impacted by wind-driven upwelling in the spring and summer of deep, nutrient-rich water. Satellite images highlight blooms of chlorophyll associated with these events that typically last 2-20 days.

The RSN Deep Profiler (DP) system is designed to collect oceanographic data profiles in water depths of up to 3000m. The DP system includes a modified McLane Mooring Profiler (MMP) vehicle that uses a motor traction drive to profile from near the sea surface to the seafloor along a tensioned mooring cable with a subsurface float. The system's dock assembly near the seafloor includes an inductive battery-charging dock for the vehicle battery, an inductive communication system that provides communications during profiling, and a Wi-fi antenna that provides high-speed communications while in the charging dock. The dock electronics will connect to the RSN power and fiber-optic data network using ROV-mateable underwater connectors. (Illustration by Nick Michel-Hart, University of Washington)
