The USGS-St. Petersburg Carbon Analytical Laboratory utilizes state of the art methods and instrumentation for quantifying carbon system parameters in aqueous samples.  The laboratory operates Ocean Optics USB 2000 spectrometers to determine spectrophotometric total alkalinity and UIC Model CM5014 CO2 Coulometers with Model CM5130 Acidification Modules, to measure total carbon in aquatic ecosystems ranging from estuaries to open marine systems and from the equator to poles. Analytical methods are derived from Yao and Byrne (1998), DOE (1994), and Dickson et al. (2007). Certified reference materials for instrument calibration and quality assessment are from A. Dickson (Scripps Institution of Oceanography).
