WASHINGTON - NASA satellites that monitor ocean color and temperature have joined a global effort to study the worrisome bleaching of coral in Australia's Great Barrier Reef, the US space agency said on Wednesday.
Coral reefs get bleached when water is too warm, which forces out tiny algae that live in the coral and help it to thrive and give it its vivid color, NASA said in a statement. Without these algae, coral can whiten and eventually die.
"Australia's Great Barrier Reef is the largest and most complex system of reefs in the world, and like so many of the coral reefs in the world's oceans, it's in trouble," said oceanographer Gene Carl Feldman of NASA's Goddard Space Flight Center outside Washington.

"The Great Barrier Reef is an icon, and we just want to know what we can do to save it," said Weeks in the statement. "Sea surface temperatures over the last five months are actually higher in certain locations now than they were in 2002 when we witnessed the worst bleaching incident to date."
