Ocean's 'twilight zone' may be a key to understanding climate change

...a and recycled in the "twilight zone," a dimly lit area 100 to 1,000 meters below the surface. Because the carbon often never reaches the deep ocean, where it can be stored and prevented from re-entering the atmosphere as a green-house gas, the oceans may have little impact on changes in the atmosphere or...
