CO2 Times Series in the North Pacific

Caption from Scott C. Doney et al.,2009: Ocean Acidification - a critical emerging problem for the ocean sciences. Oceanography, Volume 22, Number 4, a quarterly journal of The Oceanography Society : Time series of atmospheric CO2 at Mauna Loa (in parts per million volume, ppmv; red), surface ocean pCO2 (µatm; blue) and surface ocean pH (green) at Ocean Station ALOHA in the subtropical North Pacific Ocean. Note that the increase in oceanic CO2 over the past 17 years is consistent with the atmospheric increase within the statistical limits of the measurements.
