A nearly 5 ft-long rattail eyes the ROV Jason at >5000 ft down at the summit of Axial Seamount. This solitary fish, or its friend, comes to see us each year. Credit: UW/NSF-OOI/WHOI; V19.

A nearly 5 ft-long rattail rests just above a lava flow on the summit of Axial Seamount, nearly a mile beneath the oceans' surface. White bacterial mats fill small cracks in the seafloor. Credit: UW/NSF-OOI/WHOI;V19.

A newly formed very active venting 'John Casey'site hosts beautiful healthy tubeworms with bright red plumes. A small black beehive chimney releases hot fluids into the near freezing seawater. Credit: UW/NSF-OOI/WHOI; V19.

A fragile sulfide (beehive) structure sprouts in the John Casey area on the massive ~ 55ft tall El Guapo Edifice. Sulfide worms colonize the side of the actively venting chimlet. Credit: UW/NSF-OOI/NSF: V19.

A nearly 1 m-tall, 1 day-old chimney springs from a venting orifice where a temperature-chlorinity probe is inserted sending real-time data to shore. Credit: UW/NSF-OOI/WHOI;V19.

The Diva vent site is hosted atop a narrow volcanic ridge in the International District Hydrothermal Field. A cabled sensor sends real-time data back to shore measuring pH-H2S- and temperature. Credit: UW/NSF-OOI/WHOI; V19.

A small anhydrite-rich deposit encrusts the pH-H2S-temperature sensor at the DIva vent site after 1-day since its installation. UW/NSF-OOI/WHOI; V19.

A 1-day old deposit of fine-grained sulfide and and anhydrite (CaSO4) encrusts the pH-H2S-Temperature sensor at Dive, sending data live from 300 miles off shore. Credit: UW/NSF-OOI/WHOI. V19.

>300°C vent fluids form flame-like structures at the summit of the ~ 55 ft tall hot spring deposit "El Guapo". Credit: UW/NSF-OOI/WHOI; V19.

Streams of super heated hydrothermal fluids issue from the summit of the hot spring deposit "El Guapo". Sulfide worms colonize warm parts of the outer walls, supported by nutrients in the fluids. Credit: UW/NSF-OOI/WHOI; V19.
