A solitary anemone lives on the sediment seafloor with brittle stars at the base of Axial Seamount. This may be a Jack-o-Lantern Lid anemone. Photo credit: NSF-OOI/UW/CSSF; Dive R1715, V14.

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 entire crew turns out for hand spooling ~800 ft of extension cable back onto the ROCLS drum that was recovered from the seafloor. Hard work, but lots of smiles. Photo credit: Mitch Elend, University of Washington, V14.

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. The small black marble in the yellow plate at the instrument base indicates that the platform it level. Photo credit: NSF-OOI/UW/CSSF; Dive R1723; V14.

A short-period seismometer was installed and connected to a junction box in the International District hydrothermal field at the summit of Axial Seamount. Photo credit: NSF-OOI/UW/CSSF; Dive R1719; 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.
