Sensor Embedded in 1 Year Old Chimney

Sensor Embedded in 1 Year Old Chimney

The wand of the temperature – resistivity sensor is embedded in 1-year old metal sulfide and sulfate minerals precipitated from hot hydrothermal fluid. This novel instrument, built by M. Lilley at the University of Washington, measures real-time changes in fluid temperature and resistivity as an analogue for chlorinity. Boiling vents often emit 'fresh', low-salinty fluids.
