In December, NOAA received its second FEMA Recovery Support Mission Assignment to enable “U.S. Virgin Islands (USVI) Coral Reef Emergency Response and Restoration for Sustainable Ocean Economies, Food Security, and Storm Surge Mitigation.” In the aftermath of major storm events such as the 2017 hurricane season, NOAA often holds a seat at the table during mission assignments for federal natural resource recovery. Reef systems in these territories are vital to the ecosystem, mitigating damages to coastlines from waves and storm surge.

How NOAA Supports Post-Storm Coral Restoration

As the Earth’s atmosphere and ocean continue to warm under the global threat of climate change, the future of coral reefs looks bleaker than ever before. With rising temperatures comes an increase in mass coral bleaching events, infectious disease outbreaks, and the process known as ocean acidification. Climate change not only affects the overall health of corals, it also impacts their resiliency. Changes to the frequency and intensity of tropical storms — another side effect of climate change — lead to storm seasons that do a massive amount of damage to coral reefs.

Sea Urchins Battle to Save Hawaii Coral Reef alyssa.dillon Tue, 02/21/2017 - 15:31

Can tiny sea urchins save a Hawaiian coral reef? In Oahu’s Kaneohe Bay, with a little help from scientists, it appears they can.

Kaneohe Bay has been plagued for decades by two species of invasive algae that blanket the native coral reefs, blocking the sun. The National Oceanic and Atmospheric Administration and partners developed two methods to destroy the invaders, vacuuming them up, and releasing hungry native sea urchins to munch them away.

The waters surrounding the Puerto Rico archipelago are known for the diversity and beauty of the coral reefs. Those reefs are also under great pressure from population density, land uses, and shipping traffic.

U.S. coral reefs are impacted by 3 ­- 4 large groundings a year.  On Dec. 15, 2009 the danger became reality near Guayanilla Bay, Puerto Rico when the liquid natural gas carrier Matthew grounded on the coral reef there causing substantial harm. It wasn’t just the grounding that injured the coral. During attempts to free the tanker the bow of the ship was moved from side to side causing further injury to the reef structure.
