Mushroom Orifice Booming

The orifice at the base of the hydrothermal chimney called Mushroom is marked by a strong jet of high temperature hydrothermal fluid. Sulfide worms, scale worms and limpets are bathed in a mixture of the high temperature fluid and seawater. Credit: UW/NSF-OOI/WHOI, V18.

Hydrothermal Vent Diva in 2014

The anhydrite chimney 'Diva' visited with the ROV ROPOS during the VISIONS'14 program. This is an extremely CO2-rich vent with temperatures measured at 294°C (561°F) in July.

Inferno Hydrothermal Vent 2013

The ~ 4 m tall chimney called Inferno in the ASHES hydrothermal field sprouts a very young (< 2 year old) fragile beehive. The beehive structure is composed of very fine-grained sulfide minerals and anhydrite. Lush assemblages of tube worms, palm worms and limpets grow on the outer walls of the edifice. VISIONS '13, LEG 4.

Resistivity and Temperature Instrument in Escargot

A resistivity-temperature probe, developed by Dr. Marv Lilley at the University of Washington, was deployed into a 270°C actively venting orifice on the chimney called Escargot. Resistivity is an analogue for chlorinity. Some of the vents in the International District are boiling, causing release of very gas-rich, low-salinity fluids. This instrument, recovered on ROPOS dive 1638, was deployed on a small ledge on the structure a few weeks previously with power provided by batteries in the titanium housing. The orange-white taped cable leads to the wand that is inserted into the chimney (not shown in this image). The white, feathery material on the outside of the chimney is filamentous bacteria, supported by low-temperature diffuse fluids that waft up the side of the chimney. Photo credit: NSF-OOI/UW/CSSF

Fires in the Sea

High-temperature, near-boiling fluids jet from small spigots on the top of the metal-sulfide, black-smoker chimney called El Guapo (the handsome one) in the International District Hydrothermal Field. VISIONS '13, Leg 4.

Small Chimlets at Base of Mushroom Vent

Small sulfide chimneys vent high temperature fluids at the base of the Mushroom sulfide edifice. Dense tubeworm (red plumes), palm worm (brown red plumes), and limpet macrofaunal assemblages completely cover most of the edifice. VISIONS '13, Leg 4

Smokin Hot

A young smoker near the base of the suflide edifice called 'Mushroom' emits particle-poor, shimmering water at temperatures  >100oC.  Tube worms, palm worms and limpets bathe in diffusely flowing fluids that vent out of the porous chimney walls and mix with the surrounding, nearly freezing seawater. A high definition camera will be installed at this site providing real-time live imagery in 2014. (VISIONS '13 Dive R-1614)
