Gases dissolved in the oceans

Identify that gases are normally dissolved in the oceans and compare their concentrations in the oceans to their concentrations in the atmosphere



  • Carbon dioxide is relatively more abundant in the ocean than in the atmosphere.
  • This is caused by the hydrolysis of carbon dioxide to form carbonic acid.
  • Gases are generally less concentrated in the ocean than they are in the atmosphere.
  • The surface layers are usually saturated in atmospheric gases due to wave action.
