Deep reefs, referred to as mesophotic coral ecosystems, can be found from 100-330 feet in the eastern Gulf of Mexico. Pictured is a scamp grouper at 320 feet off the Dry Tortugas.

NOAA’s National Centers for Coastal Ocean Science has awarded $998,703 to the University of Miami to investigate how the deep coral reefs of Pulley Ridge may replenish key fish species and other organisms in the downstream reefs of the Florida Keys National Marine Sanctuary and Tortugas Ecological Preserve.
Pulley Ridge, a relatively healthy coral ecosystem off the southwest coast of Florida, is home to important commercial and recreational fisheries such as grouper and snapper. With the well-documented decline of Florida’s reefs, areas like Pulley Ridge may serve as sources of larvae that can help sustain the Florida Keys’ reef ecosystem and the tourism economy that depends on it. With more of this type of information, resource managers will be better positioned to develop more effective strategies to protect these reefs.

Colors represent water depth, which ranges from 33 feet (red) to depths of 820 feet or greater (dark blue). Current arrows depict prevalent current direction.

"We’re trying to understand not only whether these ecosystems have resources in common, but also the mechanisms of connectivity between them," said Daniel J. Basta, director of NOAA’s Office of National Marine Sanctuaries. "This will give managers information they need to protect reef ecosystems, as well as critical underwater corridors that help replenish Florida’s reefs."
The $998,703 grant is for the first year of the 5-year project led by the University of Miami, and represents a collaboration of more than 30 scientists at ten different universities pooling their expertise with state and federal agency scientists through NOAA’s Cooperative Institute for Marine and Atmospheric Studies at the University of Miami in coordination with the Cooperative Institute for Ocean Exploration, Research, and Technology at Florida Atlantic University.
NOAA’s mission is to understand and predict changes in the Earth's environment, from the depths of the ocean to the surface of the sun, and to conserve and manage our coastal and marine resources. Join us on Facebook, Twitter and our other social media channels.
