Pristine Caribbean corals studied for reasons why

From an article posted on UnderwaterTimes.com:

Washington, D.C. (Jan 24, 2008 16:36 EST) A NOAA-sponsored expedition is investigating shallow and deep coral ecosystems off the Caribbean island of Bonaire, part of the Netherland Antilles. Multiple underwater robots and divers are surveying arguably the most pristine coral reefs in the Caribbean to learn why they remain relatively healthy while many in the Caribbean and around the world are threatened. The mission is one of the first in the International Year of the Reef 2008. . . .

In shallower waters, the team is measuring changes from limited surveys in the 80’s and 90’s. In deeper waters, three robots called Autonomous Underwater Vehicles, will survey the “Twilight Zone,” 65 to 150 meters deep, where sunlight is scarce and little is known about reef systems.

“We believe this is the first science expedition using multiple AUVs to chart Bonaire’s reefs and likely the first to do so on coral reefs anywhere,” said expedition leader Dr. Mark Patterson of the Virginia Institute of Marine Science, College of William & Mary. “This is important because of scale, AUVs obtain wide-area data, allowing scientists to pinpoint further investigation.”
