The ocean is changing, spectrophotometers are slow, and tracking ocean acidification becomes more critical by the day. Generating the necessary time-series to measure changes in ocean pH requires a new set of tools. To measure the impact of ocean acidification, the Sea-Bird Scientific suite of ISFET pH sensors represent the next generation of ocean pH research.

These pH sensors are capable of long-term deployments on moorings and fixed platforms, providing the pH accuracy and resolution required for ocean acidification research. The solid-state ISFET sensor’s low drift provides dependable stability for long-term studies, with potential for over 1 million samples and up to a year between service and calibration.

Sea-Bird Scientific ISFET pH sensors are used extensively for:

  • Ocean Acidification Research
  • Coral Reef Research
  • Coastal Marine Biology
  • Environmental Monitoring
  • Coastal and Open Ocean Moorings

The Deep SeapHOx™ V2 combines the Deep SeaFET pH sensor with the SBE 37-SMP-ODO MicroCAT CTD+DO sensor. The Deep SeapHOx™ V2 allows for the integrated data collection of pH with the critical oceanographic and biological measurement of temperature, salinity, and oxygen.

  • High-accuracy ISFET pH sensor
  • Long-term deployment stability
  • Internal memory and batteries support 1-year autonomous deployments
  • Integrated pump and flow path shared with the CTD
  • Replaceable anti-foulant cartridges prevent biofouling in all environments
  • Industry leading CTD and dissolved oxygen data—the field-proven SBE 37 CTD family has more than 10,000 instruments deployed world-wide
