Ocean Acidification

Ocean acidification refers to the process of seawater pH decreasing (“increased acidity”) as the ocean absorbs CO2.  Ocean Acidification can have a significant impact on marine species, especially organisms that rely on calcium carbonate to build and maintain their shells and skeletons. With funding from NOAA and IOOS, and in support of the West Coast shellfish industry; AOOS, NANOOSCeNCOOS, and SCCOOS have added Ocean Acidification monitoring to its ongoing observations of the coastal ocean. This project funds a CO2 analyzer (Burkeolator) that has been developed by scientists at Oregon State University.

SCCOOS and the Martz Lab at the Scripps Institution of Oceanography operate several instruments at the Agua Hedionda Lagoon (AHL), Carlsbad CA. AHL consists of three sub lagoons, the outermost (nearest ocean) lagoon is the location of the Carlsbad Aquafarm ishellfish hatchery and location of the Burkeolator instrument.   
  • Burkeolator - Location: outer lagoon; Measuring: dissolved inorganic carbon, pCO2, pH, temperature, salinity.
  • SeapHOx_1 - Location: outer laboon; Measuring: pH, O2, temperature, pressure, salinity.
  • SeapHOx_2 - Location: middle lagoon (to be deployed); Measuring: pH, O2, temperature, pressure, salinity.
  • SeapHOx_3 -  Location: inner lagoon (to be deployed); Measuring: pH, O2, temperature, pressure, salinity.
