Cuban coral reefs thought to be among region’s most pristine
Tourists won’t be the only beneficiaries of easing tensions between the U.S. and Cuba. Scientists working in the Caribbean will also be able to find new opportunities for collaboration, according to federal officials.
“Ocean currents know no boundaries,” said Billy Causey, regional director of NOAA’s Office of National Marine Sanctuaries‘ Southeast Atlantic, Gulf of Mexico and Caribbean region. “They’re a conveyor belt, moving important marine life between our countries. Working together will help us better preserve these natural resources to benefit people in both our countries,” Causey said.
‘If we don’t take action … coral reefs will not survive into the next century’
The most dangerous effects of global warming may still be decades away, but ocean scientists say that the buildup of carbon dioxide is already slowing down the growth of coral reefs. By simulating ocean acidification on a section of the Great Barrier Reef, the researchers showed that excess C02 in the atmosphere is affecting coral reefs.
“Our work provides the first strong evidence from experiments on a natural ecosystem that ocean acidification is already causing reefs to grow more slowly than they did 100 years ago,” said study lead author Rebecca Albright, a marine biologist in Carnegie’s Department of Global Ecology in Stanford, Calif. “Ocean acidification is already taking its toll on coral reef communities. This is no longer a fear for the future; it is the reality of today.” Continue reading “Study says ocean acidification has already slowed coral growth”→
“We’re maybe looking at a 2- to 2.5-year-long event. Some areas have already seen bleaching two years in a row,” said Mark Eakin, a biological oceanographer with the National Oceanic and Atmospheric Administration in College Park, Maryland, and coordinator of the agency’s Coral Reef Watch.
Scientists with Oregon State University studied the event and reported their findings in the journal Frontiers in Microbiology, explaining how their research is important in the context of an ongoing global coral reef bleaching event.
“This is bad news,” said Rebecca Vega-Thurber, an assistant professor of microbiology in the OSU College of Science and corresponding author on the study. “This bleaching event occurred in a very short period on a pristine reef. It may recover, but incidents like this are now happening more widely all around the world. This research suggests that viral infection could be an important part of the problem that until now has been undocumented, and has received very little attention,” she said.

The creation of the world’s largest marine park in the Americas could help rebuild fish stocks off the coast of South America, ocean experts said this week, hailing Chile’s announcement that it will protect 297,518 square kilometers as a no-take zone. With the formation of Nazca-Desventuradas, Chile will now protect 12 percent of its marine surface area
