WHOI dock testing of a total Dissolved Inorganic Carbon (DIC) and pH sensor package. It measures seawater pH and DIC concurrently based on spectrophotometric principles. Because of this concurrent measurement strategy, it can fully characterize the seawater CO2 system with one instrument. The sensor was designed for buoy deployment. It is particularly useful for carbon cycle and ocean acidification studies.
Image Of the Day caption:
On the WHOI dock, research assistant Katherine Hoering and MIT-WHOI Joint Program student Sophie Chu test a self-contained package of sensors that can fully characterize the CO2 system in seawater. Marine chemist Aleck Wang developed this instrument in collaboration with WHOI engineers for his labs research on ocean acidification and the carbon cycle. The instrument, which will be attached to a buoy, can measure and record transmit the pH level and total dissolved inorganic carbon (DIC) and transmit the data back to their lab in real-time.
