The broadband seismometer (left) and low frequency hydrophone (right) are installed on the floor of Axial Seamount at the Central Caldera Site. 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.

Sea cucumbers (Phylum Echinoderm, Class Holothuria) are common in the sediments at the base of Axial Seamount.  This one is an unknown species of the genus Peniagone. Photo credit: NSF-OOI/UW/CSSF; Dive R1715; V14

This small sea cucumber (Holothurian) belongs to the Peniagone genus. It is common at the base of Axial.  Photo credit: NSF-OOI/UW/CSSF; Dive R1714; V14

This small sea cucumber (Holothurian) belongs to the Peniagone genus. It is common at the base of Axial. Its undulating motion allows it to swim from place to place.  Photo credit: NSF-OOI/UW/CSSF; Dive R1599; V13

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.

All Secondary Infrastructure is now installed and connected to junction box MJ03D – it awaits connection to Primary Node PN3B.  a) The bottom pressure-tilt instrument (BOTPA303) is slung beneath the ROV ROPOS for transport to the seafloor. b) Final installation image of the short-period OBSSPA305 connected to MJ03D. c) The current meter (VEL3DB304) being placed into its final location by the ROV ROPOS. d) Final placement of the bottom pressure-tilt instrument (BOTPTA303) installed and connected.
