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.

During ROPOS Dive 1629 of the VISIONS'13 Expedition, a current meter (tripod with red legs) and pressure sensor (were powered up and tested using through the medium powered J-box MJ01A. The ROV ROPOS provided power and communications and the data were streamed live up to the R/V Thompson through ROPOS's fiber optic tether. Here , the water depth was 2900 m.

An HPIES instrument deployed off the starboard side of the R/V Sikuliaq ~ 125 km offshore Newport Oregon near the base of the Subduction Zone at Slope Base. The instrument was released and free fell 2900 m to land softly on the seafloor - the extended legs insure a softer landing and that is stays nearly horizontal as it travels through the water column. 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.
