How has the ocean's ph changed over time

WebOcean acidity is measured on the "pH" scale: liquids with a pH less than 7 are acidic and those with a pH above 7 are basic. So far, the ocean's pH has dropped from about 8.2 in preindustrial times to around 8.05. This seemingly small change may already be affecting ocean organisms—and future CO 2 emissions could lower ocean pH even further ... Web18 mei 2024 · Over time, the pH numbers will gradually rise until you add more nutrients. Temperature also affects the pH level of water. As the water warms up, it slowly releases CO2 into the atmosphere, which naturally increases pH levels. The strength of your nutrient solution could also affect pH drift.
