  • Ocean Acidification - Woods Hole Oceanographic Institution
    Ocean acidification is a reduction in the pH of the ocean over an extended period of time, caused primarily by an increase of carbon dioxide from the atmosphere
  • Frequently asked questions about ocean acidification
    Ocean acidification is a new field of research in which most studies have been published in the past 10 years Hence, there are some certainties, but many questions remain Ocean acidification is also a multi-disciplinary research area that encompasses topics such as chemistry, paleontology, biology, ecology, biogeochemistry, modeling, and social sciences Furthermore, some aspects of ocean
  • Ocean Alkalinity - Woods Hole Oceanographic Institution
    Ocean acidification has been damaging coral skeletons and shells, including those of some phytoplankton, so alkalinity enhancement has the potential to reverse ongoing damage caused by carbon dioxide driven changes in pH But before it can be used at large scales, it’s essential to determine whether such efforts will be safe for marine
  • Carbon Dioxide, Shell Building, and Ocean Acidification
    To build shells and skeletons, marine organisms extract calcium ions and carbonate ions from seawater to make shells
  • Carbon Dioxide in Seawater - Woods Hole Oceanographic Institution
    When carbon dioxide mixes with seawater it has the effect of reducing the availability of carbonate ions, which many marine organisms need to build their shells
  • FAQs about Ocean Acidification - Woods Hole Oceanographic Institution
    Introduction Ocean acidification is a new field of research in which most studies have been published in the past 10 years Hence, there are some certainties, but many questions remain Ocean acidification is also a multi-disciplinary research area that encompasses topics such as chemistry, paleontology, biology, ecology, biogeochemistry, modeling, and social sciences Furthermore, some
  • Ocean Warming - Woods Hole Oceanographic Institution
    Ocean Acidification Coastal ocean acidification sets off a chain of chemical reactions that lowers the ocean’s pH, making it more acidic Acidification can affect many marine organisms, especially those that build their shells from calcium carbonate such as the scallops shown here (Photo by Erin Koenig, Woods Hole Oceanographic Institution)
  • Ocean acidification is no big deal, right? - Woods Hole Oceanographic . . .
    Some people argue that ocean acidification isn't an issue of concern After all, they say, the ocean isn't actually acidic There is some truth to that On the pH scale, which runs from 0 - 14, pure water lands at a neutral 7 Ocean water has a pH of 8, so it is slightly alkaline, or basic But that argument misses the point Acidification refers to how the pH has changed over time: ocean
  • OCB-OA_labkit102609 - Woods Hole Oceanographic Institution
    Thanks for your interest in teaching about ocean acidification! As you probably know, ocean acidification is a consequence of human emissions of carbon dioxide to the atmosphere Even though there is increasing media coverage on this topic, many people find ocean acidification difficult to accept or understand because they aren’t familiar with the science behind it We hope that these hands
  • The pH Scale - Woods Hole Oceanographic Institution
    pH is a measure of the concentration of hydrogen ions in a solution The more hydrogen ions that are present, the more acidic is the solution The pH scale ranges from zero (very acidic) to 14 (very basic)
