Los beneficios sociales y económicos de la restauración de arrecifes de coral en Puerto Rico

PUNTOS CLAVE

La restauración de los arrecifes de coral puede producir beneficios significativos en la reducción de inundaciones. Estas defensas naturales sufrieron daños a causa de los huracanes de 2017; su recuperación reduciría riesgos adicionales a la naturaleza, las personas y propiedades causados por tormentas.

Coral reef restoration can yield significant flood reduction benefits. These natural defenses were damaged in the 2017 hurricanes; their recovery would reduce the risks of further storm damages to nature, people and property.

Four scenarios for the southern part of the Florida coastline show the increase in annual coastal hazard risk due to projected coral reef degradation.

Maps show the potential decrease in annual coastal hazard risk provided by coral reef restoration in Florida.

Maps of Puerto Rico show the increase in annual coastal hazard risk due to damage by Hurricanes Irma and Maria.

Report Summary

The Social and Economic Benefits of Coral Reef Restoration in Florida

Targeted restoration of reef natural infrastructure can protect U.S. people and property from significant risk of future flooding.

Key Points

Bathymetry data from various sources, including newly released 2018 and 2019 multibeam data collected by the National Oceanic and Atmospheric Administration (NOAA) and the U.S. Geological Survey (USGS), were combined to create a composite 30-m resolution multibeam bathymetry surface of the southern Cascadia Margin offshore of Oregon and northern California.

An anchor station in 20m water depth with a wave buoy and smart mooring attached. This instrument will deliver high-fidelity, real-time wave, water level, and wind data to scientists at the USGS St. Petersburg Coastal and Marine Science Center.

A novel stereo CoastCam will be installed on at dune at Pea Island for the duration of the experiment.

The R/V Sallenger tows the SQUID-5 over Looe Key reef with a NOAA Sanctuary boat in the background patrolling the Looe Key area to warn recreational vessels of the ongoing research activity.

This beautiful red jellyfish in the genus Poralia may be an undescribed species. It was seen during the third transect of Dive 20 of the 2021 North Atlantic Stepping Stones expedition, at a depth of 700 meters (2,297 feet).

Towards the end of Dive 19 of the 2021 North Atlantic Stepping Stones expedition, we continued to observe the scattered rock debris sitting on the lobate and pillow lava outcrops that we’d seen earlier, suggesting that the pinnacle of Retriever Seamount was perhaps a late-stage eruption site and that it remains largely susceptible to continued erosional modification

This large bubblegum coral (Paragorgia arborea) was observed during Dive 19 of the 2021 North Atlantic Stepping Stones expedition. Based on published radial growth rates for this species, this colony is approximately 100 years old!

Remotely operated vehicle Deep Discoverer surveys a large boulder covered in bamboo corals during the 2021 North Atlantic Stepping Stones expedition. Bamboo corals were locally abundant on these large boulders and more spread out throughout different hard-bottom habitats.
