Webb29 jan. 2024 · The research team developed a numerical model simulating this detailed skeletal growth mechanism and coupled it with projected changes in ocean pH (a measure of its acidity) induced by global climate change. The results showed that declines in coral skeletal density will occur on many coral reefs. Webbocean can be described by considering changes in ΣCO2 and TA (Figure 2). Invasion of CO2 from (or release to) the atmosphere increases (or decreases) ΣCO2, respectively, while TA stays constant. This leads to a rise and drop of [CO2], respectively, with opposite change in pH (since CO2 is a weak acid).
