Ocean Acidification: Introduction, Causes, Effects, and Solutions


  • The consistent decrease of PH level of ocean water is called ocean acidification.
  • Carbon dioxide released from the burning of fossil fuels dissolves in seawater and produces carbonic acid, and this lowers the pH of the ocean water. Finally leads to ocean acidification.
  • According to the recent research reports, Ocean acidification is progressing rapidly around the oceans of the world.
  • The Pre-Industrialization pH of the ocean water was 8.179, which came down to 8.1074 in the 20th At present, the pH of the Ocean water is 8.069.
