Measuring Boiling Fluids 5000 feet Deep

A temperature-resistivity sensor, with its wand now embedded in a sulfate-rich chimney (white, right) sends real-time data to shore from the Escargot chimney, 5000 ft beneath the oceans' surface and >300 miles offshore. Resistivity is an analogue for fluid chlorinity. Numerous hydrothermal vents in the International District Hydrothermal Field at the summit of Axial Seamount are boiling. Credit.
