Rich Coral Reefs in Nutrient-Poor Water: Paradox Explained?Publication: National Geographic News Date: November 7, 2001 View Article
Coral reefs are the rain forests of the oceans, teeming with a biological diversity that boggles the mind. Just how did such profusion of life come to thrive in crystal-clear—and thus nutrient poor—water? The question has eluded scientists since Charles Darwin took his famous voyage on the H.M.S. Beagle in the 1830s.
