Nitrogen In The Air Feeds The Oceans

Summary:
A new study provides the first direct evidence that atmospheric nitrogen is an important nutrient for marine life. The finding suggests a theoretical mechanism for removing carbon dioxide from the atmosphere. Previous estimates suggested that nitrogen fixation from the atmosphere played only a very minor role in the oceans.

A team led by biological oceanographer Douglas Capone has confirmed that certain aquatic microorganisms draw huge amounts of nitrogen from the air.

A decade-long USC study has written the ending to a long-standing mystery: Where do marine organisms in the tropical oceans get the nitrogen they need to grow?
