The engineeing team from the Applied Physics Laboratory at the UW and the crew of the R/V Sikuliaq prepare the low-power junction box for installation at the Slope Base site near the Cascadia Margin, 9500 ft beneath the oceans' surface. Credit. M. Elend, University of Washington, V16.

A 12 pin electrical wet-mate connector on a junction box at the base of Axial Seamount awaits its mate during turning of the platforms and instruments at this site. The oil-filled mates, allow the ROV to disconnect and connect extension cables on platforms, junction boxes, and instruments without bringing the entire assembly to the surface. They are used heavily on our system to reduce operations and maintenance costs. Credit: UW/OOI-NSF/WHOI, DIve J907, V16.

A broadband seismometer and a low-frequency hydrophone placed on a flat basaltic plateau at the Axial Seamount Central Caldera Site, awaiting connection to medium power J-Box MJ03F. On a follow-on dive a 4.6-km cable will be installed. This area is of particular interest because the caldera floor is rapidly being uplifted, suggesting that melt is migrating into the magma chamber below.

During ROPOS Dive R1724, the junction Box MJ03F was deployed at the Central Caldera Site. It will host a broadband seismometer, a low-frequency hydrophone, and a bottom pressure-tilt instrument suite. Photo credit: NSF-OOI/UW/CSSF; Dive R1726; V14.

On July 20, the medium-powere junction box MJ03C was installed in the International District hydrothermal vent field on ROPOS Dive R1717. It was connected to a ~2300-m-long cable (RSO3W6) that will connect this system to Primary Node PN3B. A temperature-resistivty sensor (TRHPHA301) is inside the J-Box, awaiting installation during a follow-on dive. Photo credit: NSF-OOI/UW/CSSF; Dive 1717; V14.

On July 18, 2014 the Low-Voltage Node LV03A was deployed at Axial Base. It was moved on R1715 to its final location. It will provide power and communications to two moorings to be installed at this site. Primary Node PN3A is to the right. Photo credit: NSF-OOI/UW/CSSF; Dive R1714; V14.

Medium-Power Junction Box MJ03C rests on the platform for ROPOS, awaiting connection to the underbelly of ROPOS. This node was installed on the seafloor during dive R1717.

The 1 km extension cable from the Primary Node PN3A at the base of Axial Seamount is connected to the low voltage node LV013A, which will feed the two moorings at this site. Photo credit: NSF-OOI/UW/CSSF; Dive R1717; V14.

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.
