Axial Caldera ROPOS Dive 1727

During Leg 1 of the OOI-NSF VISIONS'14 Expedition, we are making significant progress in the installation of secondary infrastructure at the summit of Axial Seamount. Infrastructure shown in green is deployed on the seafloor. During ROPOS Dive R1727, the ~ 4.6 km extension cable from PN3B to MJ03F at Central Caldera will be installed, completing this site.

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.

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.

Fredrik Ryden created a prototype 3D visualization of ROPOS dives for his student project.  This image shows 15 dives simultaneously on Axial Caldera's bathymetry.  The black lines are the RSN cable routes extending from Primary Node PN3B (on the lower right of the image).

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 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.
