Sunburst Sensors Selected to Provide Instruments for OOI Water Measurements
(From OOI website - January 24, 2012 - original article here)
The Consortium for Ocean Leadership, with funding from the National Science Foundation, has selected Sunburst Sensors, LLC, of Missoula, Montana, to provide pH (PHSEN) and Partial Pressure of Carbon Dioxide in Water Instruments (PC02W) for the Ocean Observatories Initiative (OOI).
Under the $2.5 million contract, Sunburst will provide up to 77 PHSEN and 35 PC02W instruments.
Sunburst Sensors designs and manufactures instruments that measure inorganic carbon parameters pC02, pH and total alkalinity. Sunburst's Submersible Autonomous Moored Instrument (SAMI) measures and logs levels of dissolved chemicals in sea and fresh water.
The SAMI-pH and SAMI-CO2 both use the indicator method for measurement of pH in oceanic waters. Measurement of pH and the amount of dissolved CO2 in seawater are critical to the determination of carbon flux between the ocean and atmosphere, and understanding ecological and climatological effects of ocean acidification.
