A rattail fish (Grenadier) investigates two pressure sensors at 9500 ft water depth at the sedimented Slope Base site. The one in the background has been equilibrating since 2017 on the seafloor. Venus fly-trap like anenomies have colonized the cables that allow data to flow to shore in real-time, and a feeding sea star is on the dusty, 2014 sensor. Credit: UW/NSF-OOI/WHOI, V18.

An instrumented "Platform Interface Assembly" from the Slope Base site is recovered onto the deck of the R/V Revelle during the OOI-NSF Cabled Array expedition lead by the University of Washington. The platform was attached to a 7,000 lb, 12 ft across mooring platform at 200 m beneath the suface. Attached to the cable it host 18 instruments sending live data to shore 24/7. Credit: M. Elend, University of Washington, V18.

An HPIES instrument is being installed off the starboard side of the R/V Sikuliaq ~ 125 km offshore Newport Oregon near the base of the Subduction Zone. This instrument utilizes a bottom pressure sensor, an inverted echosounder and a horizontal electrometer to provide insights into the vertical structure of current fields, near-bottom water currents, and water properties including temperature, salinity, and specific volume anomalies. It was built at the Applied Physics Laboratory. Credit: M. Elend, University of Washington, V16.

The Shallow Profiler Mooring 12-ft across, 7 ton platform hosts a new Science Pod (left) and Platform Interface Assembly (PIA, right) installed on Jason Dive J2-917 as part of the annual maintance operations for these moorings. The 'mother' platform sprouts a variety of life that was not present last year when we turned the Science Pod and PIA. Credit: UW/OOI-NSF/WHOI; V16.

The top of the Deep Profiler mooring at the Slope Base site is marked by a large syntactic foam float. This was installed during Leg 2 of the NSF-OOI-UW Cabled Array VISIONS'15 expedition. Credit: NSF-OOI/UW/ISS; V15 - ROPOS Dive R1855.

The Oregon Slope Base Shallow Profiler, engulfed in soft sunlight, rises to ~5 m beneath the ocean's surface. It is measuring nutrients, dissolved oxygen, seawater acidity, temperature, chlorophyll, and carbon dioxide concentrations at high temporal and spatial resolution, controlled from ~70 miles onshore through the Internet at the University of Washington.

This strange fish, Genioliparis ferox (Stein), was first described in 1978 from a single specimen and never seen afterwards. It was imaged at 2901 m at the Slope Base Site during ROPOS Dive R1757. G. ferox is a ferocious mid-water predator, with many sharp teeth. Credit: UW/NSF-OOI/CSSF; Dive R1757; V14.
