  • The U.S. National Oceanic and Atmospheric Administration (NOAA) says changes in ocean temperature are the leading cause of coral bleaching around the world.
  • 2
  • From Australia's Great Barrier Reef to the waters of Florida, it happens when warm water causes corals to expel their colorful algae and turn white.
  • 3
  • Derek Manzello is the head of Coral Reef Watch, which is part of NOAA.
  • 4
  • He said at least 35 countries and territories across five oceans and seas reported coral bleaching.
  • 5
  • He said that by the year 2040, all of the world's coral will suffer from bleaching if water temperatures do not cool.
  • 6
  • He said coral needs extended periods of cooler water to recover from bleaching.
  • 7
  • If the water does not cool, he said, "the corals aren't going to have a chance to recover."
  • 8
  • But in the Gulf of Mexico, about 160 kilometers south of Galveston, Texas, a large coral reef is still doing well.
  • 9
  • The reef is part of the Flower Garden Banks National Marine Sanctuary.
  • 10
  • The reef formation covers over 400 square kilometers.
  • 11
  • It started with just two reef areas, called banks, in 1992.
  • 12
  • It now has 17 banks.
  • 13
  • It is described as undersea mountains of yellow, orange and pink coral as far as the eye can see.
  • 14
  • Michelle Johnston oversees the protected marine area for the federal government.
  • 15
  • She said seeing that much coral in one place is "magnificent" and rare.
  • 16
  • Johnston said fishermen used to tell the story of a colorful area in the Gulf of Mexico far from shore 100 years ago.
  • 17
  • But, scientists were uncertain that a coral reef could exist in such deep water.
  • 18
  • When divers finally reached the reef in the 1960s, they were surprised to find marine life.
  • 19
  • Johnston said the plants and animals do so well because the reef formed on top of mountain-like salt domes, high enough to catch sunlight.
  • 20
  • During the recent summer of record-breaking heat, Johnston said, the reef did experience some bleaching but nothing as serious as in other parts of the world.
  • 21
  • But that does not mean the reef in the Gulf of Mexico is not vulnerable to climate change.
  • 22
  • She is concerned about the area getting too hot and the coral dying off.
  • 23
  • Officials who watch over Flower Garden Banks say the reef has suffered more serious bleaching in the past, but its depth and health helped it recover.
  • 24
  • The reef is deeper - 18 meters - than many others that are often just offshore.
  • 25
  • Andy Lewis of Houston, Texas first saw the reef about 10 years ago.
  • 26
  • He loved it so much that he became an expert diver and started a company that leads dives to Flower Garden Banks.
  • 27
  • "It's just a real adventure," he said.
  • 28
  • Scientists are working to help the reefs stay healthy.
  • 29
  • For example, boats are not permitted to anchor themselves to the reefs.
  • 30
  • They must connect to special floating cables to stay in one place.
  • 31
  • Other workers help remove invasive fish and creatures from the area.
  • 32
  • Kelly Drinnen is an education and outreach specialist for the Flower Garden Banks.
  • 33
  • She said, "because coral reefs are declining all over the globe, when we find ones that are healthy, we want to keep them that way."
  • 34
  • Drinnen added that they could also provide information that can help other reefs stay healthy or recover from bleaching.
  • 35
  • In 2010, the Flower Garden Banks corals were not damaged by the large oil spill that followed the Deepwater Horizon explosion.
  • 36
  • Other reefs in the Gulf of Mexico were.
  • 37
  • So, researchers are using data from the reef to help guide the restoration of the damaged ones.
  • 38
  • Researchers are also comparing the genetics of Flower Garden Banks corals to corals in other parts of the world.
  • 39
  • And they hope to grow and possibly replant them in other places.
