Saturation state refers to the point at which something is completely filled or saturated. It means that there is no capacity left for any additional input or change. Full definition
Especially calcium carbonate skeleton building organisms are affected by the rapidly dwindling seawater pH and carbonate saturation state. (bitsofscience.org)
New NOAA - led research maps the distribution of aragonite saturation state in both surface and subsurface waters of the global ocean and provides further evidence that ocean acidification is happening on a global scale. (sciencedaily.com)
Specifically, we need to reduce land - based sources of pollution; this is particularly important for managing OA because nutrients like phosphorus and nitrogen can lower pH and aragonite saturation states in seawater. (reefresilience.org)
