Sunburst Sensors strives to provide its customers high-quality chemical sensors for marine and freshwater applications. The SAMI-CO2 and SAMI-pH (Submersible Autonomous Moored Instrument) have been deployed by researchers around the world interested in long term monitoring of pCO2 and pH. In 2011, these instruments were chosen for use by the Ocean Observatories Initiative (OOI) — a large scale endeavor funded by the National Science Foundation to construct "a networked infrastructure of science-driven sensor systems to measure the physical, chemical, geological and biological variables in the ocean and seafloor." Other customers include organizations such as Woods Hole Oceanographic Institute, Scripps, OSU-COAS, NASA, USGS, NOAA, etc. Sunburst Sensors has a strong track record of using grant funding to develop successful commercial devices. Sunburst has customers in over 20 countries.
