Carribean Coral Death/Bleaching At Unprecedented Levels

WASHINGTON (AP) — A one-two punch of bleaching from record hot water followed by disease has killed ancient and delicate coral in the biggest loss of reefs scientists have ever seen in Caribbean waters.
Researchers from around the globe are scrambling to figure out the extent of the loss. Early conservative estimates from Puerto Rico and the U.S. Virgin Islands find that about one-third of the coral in official monitoring sites has recently died.

"It's an unprecedented die-off," said National Park Service fisheries biologist Jeff Miller, who last week checked 40 stations in the Virgin Islands. "The mortality that we're seeing now is of the extremely slow-growing reef-building corals. These are corals that are the foundation of the reef ... We're talking colonies that were here when Columbus came by have died in the past three to four months." Some of the devastated coral can never be replaced because it only grows the width of one dime a year, Miller said.

Coral reefs are the basis for a multibillion-dollar tourism and commercial fishing economy in the Caribbean. Key fish species use coral as habitat and feeding grounds. Reefs limit the damage from hurricanes and tsunamis. More recently they are being touted as possible sources for new medicines. If coral reefs die "you lose the goose with golden eggs" that are key parts of small island economies, said Edwin Hernandez-Delgado, a University of Puerto Rico biology researcher.

On Sunday, Hernandez-Delgado found a colony of 800-year-old star coral — more than 13 feet high — that had just died in the waters off Puerto Rico. "We did lose entire colonies," he said. "This is something we have never seen before."

<sarcasm off>

for so long that the reef remained healthy and vibrant for years. It was my favorite place to scuba dive because it was so healthy and beautiful. This is so sad, a tragic loss to the planet. It scares me to death to think of all that is happening. Not good news.
