  • Ocean acidification - National Oceanic and Atmospheric Administration
    The ocean’s average pH is now around 8 1, which is basic (or alkaline), but as the ocean continues to absorb more CO 2, the pH decreases and the ocean becomes more acidic
  • Ocean acidification - Wikipedia
    Ocean acidification is the ongoing decrease in the pH of the Earth's ocean Between 1950 and 2020, the average pH of the ocean surface fell from approximately 8 15 to 8 05 [2]

    Ocean water is normally slightly basic, with a surface-water pH of about 8 2, but that has declined in recent years to about 8 1 A decrease of 0 1 pH units may not seem like much, but because the pH scale is logarithmic, each unit on the pH scale represents a tenfold change in acidity
  • Understanding Ocean pH Levels - numberanalytics. com
    The pH level of the ocean is a critical parameter in understanding the health and dynamics of marine ecosystems pH is a measure of the concentration of hydrogen ions in a solution, defined as the negative logarithm of the hydrogen ion activity
