Coral in a small America Samoan lagoon are thriving in hot water that would kill other coral. How?

A Natural Global Warming Lab

A field station in American Samoa has been set up in an attempt to understand the effects of climate change on coral reefs. In a lagoon on Ofu Island, the water temperature is hotter than average with wide fluctuations in temperature. If global warming proceeds as projected, eventually water temperature throughout the tropics will resemble that of this lagoon. Water as warm as Ofu's is usually deadly to coral, but colonies thrive there. A group of graduate students and faculty are transplanting coral from the warm lagoon to the cooler forereef, and vice versa, hoping to understand why these particular corals can survive the heat.
