The report issued today, The State of Coral Reef Ecosystems of the United States and Pacific Freely Associated States: 2008, says that the nation's coral reef ecosystems, particularly those adjacent to populated areas, continue to face intense human-derived threats from coastal development, fishing, sedimentation and recreational use.
Even the most remote reefs are subject to threats such as marine debris, illegal fishing and climate-related effects of coral bleaching, disease and ocean acidification.
The report was released by NOAA at the 11th International Coral Reef Symposium in Fort Lauderdale, Fla. More than 270 scientist and managers working throughout the Gulf of Mexico, Caribbean, the Atlantic and Pacific authored the 15 jurisdiction-specific chapters of the report. The scientists graded the coral ecosystems on a five tier scale: excellent, good, fair, poor and unknown.
"NOAA's coral program has made some significant progress since it was established 10 years ago, but we need to redouble our efforts to protect this critical resource," said retired Navy Vice Admiral Conrad C. Lautenbacher Jr., Ph.D., under secretary of commerce for oceans and atmosphere and NOAA administrator.
The 569-page document details coral reef conditions in the U.S. Virgin Islands, Puerto Rico, Navassa Island, southeast Florida, the Florida Keys, Flower Garden Banks, the Main Hawaiian Islands, the Northwestern Hawaiian Islands, American Samoa, the Pacific Remote Islands, the Republic of the Marshall Islands, the Federated States of Micronesia, the Commonwealth of the Northern Mariana Islands, Guam and the Republic of Palau.
"The report shows that this is a global issue," said Tim Keeney, deputy assistant secretary of commerce for oceans and atmosphere and co-chair of the United States Coral Reef Task Force. "While the report indicates reefs in general are healthier in the Pacific than the Atlantic, even remote reefs are subject to threats stemming from climate change as well as illegal fishing and marine debris."
The conditions of U.S. coral reefs have been declining for several decades according to the report's authors. As an indicator of this decline, since the last status report was released in 2005, two coral species -- Elkhorn and Staghorn corals --- have become the first corals ever listed as threatened under the Endangered Species Act.
The 2008 report is the third in a series, representing an evolving effort to track the condition of coral reef ecosystems at both local and national scales. It was called for in the National Coral Reef Action Strategy (NCRAS) and was designed to address the primary threats, goals and objectives outlined in the NCRAS, the Coral Reef Conservation Act of 2000, and other guid¬ance documents. NOAA's Center for Coastal Monitoring and Assessment's Biogeography Branch led the development and production of the report with support from NOAA's Coral Reef Conservation Program.

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.
The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...
For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.
To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...
For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.
Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...
Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.
A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...
Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.
"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
