Green-sided frames are junction boxes that will be installed at the volcano and they willl host myriad instruments. The central drum holds yellow extension cable that will connect one of the juction boxes to  Primary Node 3B, providing power and bandwith to this subsea observatory.

This beautiful image of global weather conditions is a screen shot from the http://earth.nullschool.net site. The green circle shows the approximate location of Axial Seamount. Over July 15-16, the wind shifted from westerly to northerly and increased from ~12-16 kts to 22-27 kts . Wind waves increased from ~3’ to 5-6’ during that time. The forecast is for the wind to remain sustained from 25-30 kts from the north and wind waves from 2-3m (6-10’) until Friday morning, when the wind should both shift direction and drop to ~10 kts.

A bottom pressure-tilt instrument is installed at the summit of Axial Seamount in the International District hydrothermal field. This instrument measures the rise and fall of the seafloor due to melt migration in the subsurface. Currently, the seafloor is rising and this is believed to reflect the influx of magma into the core of the volcano.The instrument rests on a frozen lava flow - called a sheet flow.

A low-frequency hydrophone (black tubular-shaped instrument in tripod with red legs), connected to a broadband seismometer, awaits installation by the ROPOS that will install this sensor in the International District 2 Site. Pea gravel bags in the background will be piled over the broadband to dampen any noise by local currents. Credit: Mitch Elend, University of Washington, V14.

The 7-function manipulator of ROPOS is connecting the extension cable to the medium powered junction box. The white bags inssulate the broadband from acoustic "noise" associated with curents flowing over the instrument.

The ROCLS cable drum with >8000 ft of electro-optical cable is lowered on the R/V Thompsons trawl wire for deployment near PN3B. ROPOS will launch shortly, and acquire the drum with a sonar at ~ 600 ft beneath the surface. Near bottom, an acoustic release will free the drum to rest gently on the seafloor so that ROPOS can latch into it and begin the cable installation at Axial Summit.

During the port call for Leg 4 in Newport, Oregon, the UW-APL-built Shallow Winched Profiler was loaded onto the R/V Thompson. The system has an underwater level wind that "spools" out yellow cable, which will provide power and communications to an attached instrument "pod" (orange bulbous-shaped package bottom left). The profiler will be located at a water depth of ~197 m on the already installed mooring at the EA Offshore Site. Several times a day the instrument pod will rise from the 197-m-deep platform to just beneath the ocean's surface making critical chemical and biological measurements.
