2014 EXCELLENCE IN PARTNERING AWARD
Development of an integrated ISFET pH sensor for high pressure applications in the deep-sea
Lead PI: Dr. Kenneth Johnson, Monterey Bay Aquarium Research Institute (MBARI)
The “Deep-Sea Durafet pH” sensor, developed by the team after several years of engineering and testing, is a prototype that now operates to 2000 meters depth and is expected to become commercially available for other ocean research projects and education. This robust and stable sensor will enable autonomous monitoring of ocean pH, especially as it relates to pH changes driven by increasing atmospheric carbon dioxide. Deep-Sea Durafet pH sensors are currently operating on profiling floats and CTD/Rosette samplers, where they are producing high quality pH profiles.
