Ocean dumps

Norwegian researchers believe that dumping carbon dioxide in the ocean could lock up the greenhouse gas for centuries. The natural process of carbon dioxide dissol-ving into the surface of the ocean can be hastened by injecting the gas into deep waters. Researchers from the Nansen Environmental and Remote Sensing Center, Norway, found that gas dumped at a depth of 800 m in the Norwegian Sea dissolves and then the heavier, gas-rich water sinks to the sea floor where it will remain for centuries ( New Scientist , June 20, 2001).
