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.

The back deck of the R/V Thompson was fully loaded with instruments, junction boxes, cable spools, and mooring components that were installed during Leg 4. Image Credit: Skip Denny, UW-APL; V14.

The two-legged Shallow Profiler Mooring was installed on ROPOS Dive R1753 at the Oregon Offshore Site (600 m). The instrumented winched shallow profiler and platform instrument systems will be installed on Leg 4. Photo credit: NSF-OOI/UW/CSSF; Dive R1753; V14.

Exposed gas hydrate (a clathrate of water ice that forms around methane) observed in Einstein,s Grotto at the Southern Hydrate Ridge summit. Large bubbles were escaping intermittently from the crevice, indicating an active methane seep. A rockfish is sheltering within the grotto as well. Credit: UW/NSF-OOI//CSSF, ROPOS Dive R1754, VI14.

We encountered a little piece of Monterey Bay Aquarium Research Institute (MBARI) at Hydrate Ridge during survey dive R1754. The flamingo has seen better days, but it is also now hosting some invertebrate friends. Photo Credit: NSF-OOI/UW/CSSF, Dive R1754, VISIONS14

Deployment of the 200m platform of the Endurance Oregon Offshore two-legged mooring, which will eventually host a winched shallow profiler and bioacoustic sonar instruments. Two mooring lines with seafloor anchors are attached to the sides of the platform (rather than the usual single mooring line) to add stability to the platform so it can act as the profiler base.

A cockatoo squid (likely Taonius borealis) encountered at 585 meters depth during a site survey between the 2-legged mooring EOM leg anchor and the low-voltage node LV01C at Oregon Offshore. The squid was red when we first encountered it, and then turned transparent as the ROV ROPOS took video. Credit: UW/NSF-OOI/CSSF, rOPOS Dive R1752, V14.
