Stacy Maenner Jones is a Physical Scientist at NOAA’s Pacific Marine Environmental Laboratory in Seattle, Washington, where she has been instrumental in the development of the moored and autonomous ocean CO₂ program, and coordinates the program’s observations, timely public access to real-time and finalized data, and sensor and observing platform development. Stacy is an essential liaison among engineers, industry partners, and scientists around the world, and has made NOAA’s moored CO₂ observations central to the global surface ocean CO₂ network. Last year, Stacy made major contributions to six Saildrone missions, including the first autonomous Antarctic circumnavigation, and oversaw a 550-day Wave Glider mission in an area where there was a critical surface ocean CO₂ observational gap in the South Pacific Ocean. Moreover, Stacy led the testing and validation of a new autonomous surface ocean CO₂ sensor, which NOAA has begun sharing with partners and stakeholders.  Stacy’s wealth of institutional knowledge and her facility with handling complex technical issues is critical to meeting NOAA’s goals of understanding changing ocean and climate conditions, and supporting healthy oceans, coastal ecosystems, and marine resources.
