Hurricane Damage to Coral Reefs in 2017 Increases Future Flood Risk in Puerto Rico and Florida

The damage to reef natural infrastructure from Hurricanes Irma and Maria puts U.S. people and property at significant risk of future flooding

Key Points

Las consecuencias significativas del riesgo de inundación debido a los daños en los arrecifes de coral causado por los huracanes Irma y María clarifican por qué los beneficios de defensa de esta infraestructura natural deben recuperarse, repararse y restaurarse.

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

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.

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.

RESUMEN DEL REPORTE

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.

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).

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!

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

New bathymetry data of the New England Seamounts collected with the EM 304 MK II variant during the 2021 North Atlantic Stepping Stones: New England and Corner Rise Seamount Chain (EX-21-04) expedition, overlaid on the Global Multi-Resolution Topography Data Synthesis grid.

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.

During Dive 11 of the 2021 North Atlantic Stepping Stones expedition, we discovered what is defined by the Oslo/Paris Convention (OSPAR) as a multispecies coral garden (100 - 700 coral colonies per every 100 square meter).
