Higher than normal ocean temperatures off Sri Lanka’s coast is threatening to damage the best coral reefs in the island, according to surveys done by marine scientists of the National Aquatic Resources Research and Development Agency (NARA).

“Underwater surveys shows widespread bleaching or whitening along the reefs, especially in shallow depths (of less than 10 meters) in the south and south west coast and also reported in Jaffna and Bar Reef in Kalpitiya,” a statement said.

Scientists say a dramatic worldwide coral bleaching event is now underway

For just the third time on record, scientists say they are now watching the unfolding of a massive worldwide coral bleaching event, spanning the globe from Hawaii to the Indian Ocean. And they fear that thanks to warm sea temperatures, the ultimate result could be the loss of more than 12,000 square kilometers, or over 4,500 square miles, of coral this year — with particularly strong impacts in Hawaii and other U.S. tropical regions, and potentially continuing into 2016.

The event is being brought on by a combination of global warming, a very strong El Nino event, and the so-called warm “blob” in the Pacific Ocean, say the researchers, part of a consortium including the National Oceanic and Atmospheric Administration as well as XL Catlin Seaview Survey, The University of Queensland in Australia, and Reef Check.
