The Value of U.S. Coral Reefs for Risk Reduction

Key Points:

  • The social and economic benefits provided by all U.S. reefs were rigorously assessed across more than 3,100 km (>1,900 miles) of coastline using hydrodynamic models coupled with census data.
  • Annually U.S. coral reefs provide flood protection benefits to more than 18,100 people and $1.8 billion in averted damages to property and economic activity.

Coastal Climate Impacts

The impacts of climate change and sea-level rise around the Pacific and Arctic Oceans can vary tremendously. Thus far the vast majority of national and international impact assessments and models of coastal climate change have focused on low-relief coastlines that are not near seismically active zones. Furthermore, the degree to which extreme waves and wind will add further stress to coastal...

Using Video Imagery to Study Wave Dynamics: Tres Palmas

Four video cameras look westward over the coast and the coral reef at Tres Palmas in Rincón, on the west coast of Puerto Rico. Two cameras look out at the horizon and over the ocean for the mid-field view; one camera offers a zoomed-in, far-field view overlooking the reef and out to the island of Desecheo, a U.S. National Wildlife Refuge; and another camera focuses on the beach.
