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.

Katie Bigham, a junior in the School of Oceanography, takes her first turn at directing ROPOS operations inside the control room. She is studying the distribution of methane seeps and biological communities at Southern Hydrate Ridge. Credti: Ed McNichol, V15.

UW undergraduate students Jesse, Lauren, and Kearstin help move a "mosquito" off of ROPOS's tool sled during Leg 1. This instrument has been measuring the flow of fluids into and out of a methane seep site at Southern Hydrate Ridge since it was installed last year. Credit: Mitch Elend, University of Washington.

Leg 1 of the Cabled Array VISIONS"15 expedition has been extremelly successful with the back deck of the R/V Thompson bulging at the seams with recovered infrastructure and instruments. ROPOS has had rapid turn arounds, pounding out dives. The science crew is tired, but happy. Credit: Mitch Elend, University of Washington, V15.

A nascent collapse zone formed since last year. ROPOS found this site by seeing bubble plumes >100 m off bottom with their sonar. Following the plume to the seafloor led us to this collapse zone. Credit: NSF-OOI/UW/ISS, V15.

The Neptunea nursery in 2015 was devoid of tending snails on top of the egg stalks. Recovery of the stalks showed that the eggs are still viable. Credit: NSF-OOI/UW/ISS, Dive R1845, V15.

A digital still camera, mass spectrometer, and fluid and microbial DNA sampler installed at the El Gordo hydrothermal chimney, International District Hydrothermal Field, Axial Seamount. A small, 1-day old chimlet sprouts from the 280°C, gas-rich vent called Dive in the International District Hydrothermal Field. NSF-OOI/UW/ISS; Dive R1839; V15.

Collapse basins marked by columns, drainback features, and arches are common features in areas where lava ponded and spilled rapidly over the seafloor in 2011.
