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.

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.

John Wonderly, a teacher from Clallam Bay School, assists with the respooling of 250 m of cable onto the ROCLS drum.  This cable totals 4.7 km in length and will be laid on the seafloor to connect Axial Caldera's Primary Node PN3B with the Central Caldera Secondary Node.

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.

The remotely operated vehicle ROPOS is launched from the R/V Thompson. ROPOS will dive to 5000 ft beneath the ocean's surface to the summit of Axial Seamount. Today the ocean in the NE Pacific is calm. Photo credit: NSF-OOI/UW/CSSF; Dive R1726; V14.

This spiny Holothurian Deep-Sea Cucumber (possibly of Genus Pannychia) has been seen on many regions of Axial Seamount. Photo credit: NSF-OOI/UW/CSSF; V13

This large purple sea cucumber (Holothurian) was seen at the base of Axial Seamount, foraging through the sediments. This one is likely Paelopadites confundens. Photo credit: NSF-OOI/UW/CSSF; V14.

These small sea spiders are Pycnogonids (Phylum Arthropoda) and live among the tube worms and limpets on hydrothermal vents of Axial Seamount. Photo credit: NSF-OOI/UW/WHOI; V11
