NOAA report finds flower garden banks sanctuary reefs among healthiest in Gulf

17.08.2009
Flower Garden Banks National Marine Sanctuary is among the healthiest coral reef ecosystems in the tropical Caribbean and Gulf of Mexico, according to a new NOAA report.

The report, A Biogeographic Characterization of Fish Communities and Associated Benthic Habitats within the Flower Garden Banks National Marine Sanctuary, offers insights into the coral and fish communities within the sanctuary based on data collected in 2006 and 2007.

Sanctuary managers will use the report to track and monitor changes in the marine ecosystem located 70 to 115 miles off the coasts of Texas and Louisiana.

"We found that 50 percent of the area surveyed for this report is covered by live coral," said Chris Caldow, a NOAA marine biologist and lead author on the report. "This is significant because such high coral cover is a real rarity and provides critical habitat for many different types of fish and other animals that live in these underwater systems."

The sanctuary is also unusual in that it is dominated by top-level predators, including large grouper, jacks, and snappers that are virtually absent throughout the U.S. Caribbean. Researchers looked at the relationship between physical measures of the sanctuary's habitat such as depth, slope and geographic location, and the nature of the fish community in each location.

"Ultimately our goal was to develop a protocol that would detect and track long-term changes in fish and sea-floor community structure," Caldow said. "Once managers are equipped with this information, they can better understand how threats from climate change and other stressors will impact the ecosystem."

The report cautions that despite the sanctuary's relatively healthy condition, it may be more susceptible to environmental impacts than previously thought. For example, scientists observed high levels of coral bleaching and corals severely impacted from hurricane activity.

NOAA prepared the report based on data collected in 2006 and 2007, with input from scientists and managers at Flower Garden Banks National Marine Sanctuary.

NOAA understands and predicts changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and conserves and manages our coastal and marine resources. Visit http://www.noaa.gov.

Im Focus: Manipulating Electron Spins Without Loss of Information

Physicists have developed a new technique that uses electrical voltages to control the electron spin on a chip. The newly-developed method provides protection from spin decay, meaning that the contained information can be maintained and transmitted over comparatively large distances, as has been demonstrated by a team from the University of Basel’s Department of Physics and the Swiss Nanoscience Institute. The results have been published in Physical Review X.

For several years, researchers have been trying to use the spin of an electron to store and transmit information. The spin of each electron is always coupled...

Im Focus: The proton precisely weighted

What is the mass of a proton? Scientists from Germany and Japan successfully did an important step towards the most exact knowledge of this fundamental constant. By means of precision measurements on a single proton, they could improve the precision by a factor of three and also correct the existing value.

To determine the mass of a single proton still more accurate – a group of physicists led by Klaus Blaum and Sven Sturm of the Max Planck Institute for Nuclear...
