GLOBAL MEAN SEA WATER PH

External Data Spec Published 01 Apr 2019
1 min read
Ocean acidification is quantified by decreases in pH, which is a measure of acidity: a decrease in pH value means an increase in acidity, that is, acidification. The observed decrease in ocean pH resulting from increasing concentrations of CO2 is an important indicator of global change.

Indicator Specification Ocean acidification This indicator illustrates the global mean average rate of ocean acidification, quantified by decreases in pH, which is a measure of acidity, defined as the hydrogen ion concentration. A decrease in pH value corresponds to an increase in acidity. The observed decrease in ocean pH resulting from increasing concentrations of CO 2 is an important indicator of change in the global ocean and the impacts of climate change. This indicator provides information on: trends in ocean acidity measured at the Aloha station; yearly mean surface seawater pH levels reported on a global scale is computed from monthly pH values by CMEMS.

Ocean acidification This indicator illustrates the global mean average rate of ocean acidification, quantified by decreases in pH, which is a measure of acidity and is defined here as the hydrogen ion concentration. A decrease in pH value corresponds to an increase in acidity. The observed decrease in ocean pH resulting from increasing concentrations of CO 2 is an important indicator of global change. This indicator provides information on: - trends in ocean acidity measured at the Aloha station; - yearly mean surface sea water pH levels reported on a global scale, based on information from the Copernicus Marine Service (CMEMS), with the estimated long-term decreasing trend.
