In graveyard of dead coral, hope and life bloom

WASHINGTON — In a ghost town of dead coral off a remote Pacific island, scientists have found a bit more life.

In excursions a year ago and then last April, scientists examined the normally stunning coral reefs around the island of Kiritimati and pronounced it mostly a boneyard of dead coral. About 85 percent of the coral was dead, 10 percent was sick and bleached but still technically alive, and only 5 percent was OK.

The same scientists returned this month and found that 6 to 7 percent of the coral is alive and not bleached, said University of Victoria coral reef scientist Julia Baum, speaking by Skype from the island.

“We left with a sense of dread and came back with a renewed purpose because there are some corals that literally came back from the brink,” said Georgia Tech climate scientist Kim Cobb. “It’s the best we could have hoped for.”

Many of the fish that rely on the reef and had been absent seem to be back.

Hot water — mostly from El Nino, the natural occasional warming of the Pacific that changes weather worldwide, and man-made global warming — had made the area one of the worst hit coral spots in the world. Nearby Jarvis Island was even more damaged. And the death of 85 percent of the coral of the much larger Great Barrier Reef has been reported, said C. Mark Eakin, coral reef watch coordinator for the National Oceanic and Atmospheric Administration.

“But despite this mass mortality, there are a few small signs of hope,” Baum said. “It’s clear that coral reefs have great resilience and the coral here is trying to recover.”

Not only has some of the bleached coral recovered, she said, but “there are coral babies that have settled on the reef sometime in the last year to year and half and these are the reef’s best hope for recovery.”
