The Hydrothermal Vent Fluid In-situ Chemistry sensor measures the chemical composition of the mineral-rich fluid plumes that emanate from cracks on the seafloor, providing insight into the sub-surface structure and dynamics of these unique habitats. Specifically it measures hydrothermal vent fluid temperature, hydrogen, hydrogen sulfide and pH.
This instrument measures the following data products. Select a data product's name to learn more.
- Hydrogen Concentration (THSPHHC)
- Hydrogen Sulfide Concentration (THSPHHS)
- pH (THSPHPH)
- Vent Fluid Temperature from THSPH (THSPHTE)
