sci.ocean-acidification Calculator
Calculates ocean pH change from dissolved CO₂ increase using carbonate chemistry equilibria and seawater buffering capacity. Ocean pH has dropped from 8.2 to 8.1 since industrialisation (30% increase in H⁺) — aragonite undersaturation threatening coral calcification is projected below pH 7.9.
Inputs
Co2 Ppm
Reference formula or conversion factor shown for context.
Salinity Ppt
Reference formula or conversion factor shown for context.
Temperature C
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Results
estimated ocean pH
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
pH drop from 1750 baseline
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
aragonite saturation state
How close the system is to its capacity limit. Above 80% sustained saturation typically leads to queuing and latency spikes.
aragonite undersaturation
How close the system is to its capacity limit. Above 80% sustained saturation typically leads to queuing and latency spikes.
pH 8.179 in 1750
pH of the solution. Below 7: acidic. 7: neutral. Above 7: basic (alkaline).
