Coral Reef Project: Puerto Rico
Science Center Objects
To better understand how waves move across coral reefs and cause flooding on tropical shorelines, USGS scientists have installed video cameras and oceanographic instruments off San Juan and Rincón, Puerto Rico. Their work is part of a study funded by USGS after Hurricanes Irma and Maria. The offshore instruments measure wave heights and speeds; the onshore video cameras show where waves break on the reef and how high they run up on the shore. USGS is collaborating with National Oceanic and Atmospheric Administration (NOAA), the University of Puerto Rico-Mayaguez, and Arrecifes Pro Ciudad to support reef-restoration efforts in the Isla Verde Coral Reef Marine Reserve and reduce flooding hazards to San Juan and its international airport.
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.

2018 Supplemental Appropriations Activities
The Additional Supplemental Appropriations for Disaster Relief Requirements Act, 2018 (P.L. 115-123) was signed by the President on February 9, 2018. This funding provided the USGS $42.2 million to support recovery and rebuilding activities in the wake of the 2017 Hurricanes Harvey, Irma, and Maria and the 2017 California Wildfires.

Assessment of Coastal Impacts in Florida and Puerto Rico
During Hurricanes Irma and Maria, much of Florida and Puerto Rico experienced significant impacts to beaches, dunes, and coral reefs. Extensive erosion, flooding, and coral losses result in increased immediate and long-term hazards to natural and populated shorelines, putting critical infrastructure at risk to future flooding and erosion and causing economic losses.
