Sentences with phrase «hydrogen ion concentration»

This increase in the ocean's hydrogen ion concentration corresponds to a reduction in pH, or an increase in acidity.

If the surface ocean pCO2 concentrations continue to increase in proportion with the atmospheric CO2 increase, a doubling of atmospheric CO2 from preindustrial levels will result in a 30 % decrease in carbonate ion concentration and a 60 % increase in hydrogen ion concentration.

pH is an indicator of acidity by measuring the hydrogen ion concentration.

The pH scale is logarithmic, so a change of 1 unit corresponds to a 10-fold change in hydrogen ion concentration.

This study projects contrasting seasonal changes of the hydrogen ion concentration, pH, and carbonate saturation state, which will exacerbate and ameliorate ocean acidification impacts.

To date, much of the focus of ocean acidification research has been on the response of calcifiers, both algae and invertebrates, to the changing carbonate system, with a particular preoccupation on one property: the hydrogen ion concentration [H +], which is frequently reported as pH owing to the relative ease of its measurement.

Surface ocean pH has decreased by 0.1 unit due to absorption of anthropogenic CO2 emissions (equivalent to a 30 % increase in hydrogen ion concentration) and is predicted to decrease by up to a further 0.3 - 0.4 units by 2100 (Caldeira and Wickett, 2003).
