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 records the following data products. To learn more about a data product, select its name.
- Hydrogen Concentration (THSPHHC)
- Hydrogen Sulfide Concentration (THSPHHS)
- pH (THSPHPH)
- Vent Fluid Temperature from THSPH (THSPHTE)
The OOI includes the following instrument models for this instrument type.
