Instruments on the Cabled Observatory

Sully and the Temperature - Resitivity Sensor
Sully and the Temperature - Resitivity Sensor

The temperature-resistivity instrument measures, in real-time, the temperature of black smoker fluids (>400°C) and the resistivity of the fluids as a proxy for chlorinity. Vents at Axial Seamount are boiling, producing fluids that are very low in chloride content (salts). Boiling is an important processes because it enhances precipitation of precious metals in seafloor black smokers.

A wide variety of instruments will be installed on cabled network study sites. Some installations took place in 2013; the remainder are scheduled for 2014.

The following instruments will be deployed as part of the Benthic Experiment Package, a multi-instrument platform at the Endurance Offshore site (PN1C):
