Coral Reef Ecosystems
Informing and Enhancing Coral Restoration
Who We Are
What We Do
Our research aims to identify corals that are more resilient in the presence of stressors like warming oceans, ocean acidification, and spread of novel diseases. Informing coral selection by managers and enhancing tools available to maximize coral resilience allows resource managers to be more effective with their restoration plans, especially when out-planting corals to the reef.
Drifter surface pressure observations contribute to decrease the total global forecast error by approximately 3%. In particular, case‐studies reveal that drifting buoy observations can be especially important to reduce the forecast error on complex or rapidly evolving cyclogenesis.

NOAA Scientists Return to Cheeca Rocks, Find Reef Completely Bleached
August 2, 2023
The growing concerns of coral bleaching due to the ongoing marine heatwave across South Florida, the Gulf of Mexico, and the greater Caribbean led scientists at NOAA’s Atlantic Oceanographic & Meteorological Lab (AOML) to return to Cheeca Rocks on July 31st and August 1st, 2023.

Research Impacts & Key Findings
AOML’s Coral Restoration and Resilience research has found that corals exposed to variable temperature treatment in the laboratory for 90 days were better able to withstand the warmer ocean temperatures caused by climate change. The temperature-treated corals were also less likely to succumb to bleaching, while untreated corals experienced more rapid tissue loss and necrosis. These findings offer coral restoration scientists with a new approach to potentially increase the success rate of planting nursery-raised staghorn coral onto degraded reefs. Currently, tens of thousands of acroporid colonies are raised and outplanted on Florida’s coral reef every year, with >70% survivorship observed one year after outplanting.
AOML’s coral scientists have led 16 National Coral Reef Monitoring Program cruises to six field sites in the Atlantic, Caribbean, and Gulf of Mexico gathering valuable data used to provide a comprehensive view of the effects of climate change on coral reef ecosystems. Over 3000 water samples have been processed. This data has been used to examine coral response to precise, controlled changes in environmental conditions and determine coral resilience to stressors such as rising temperatures, ocean acidification, and nutrient flux.

The influences of diurnal variability and ocean acidification on the bioerosion rates of two reef-dwelling Caribbean sponges
Morris, J., Enochs, I., Webb, A., de Bakker, D., Soderberg, N., Kolodziej, G., & Manzello, D. (2022). The influences of diurnal variability and ocean acidification on the bioerosion rates of two reef‐dwelling Caribbean sponges. Global Change Biology.
Abstract: Ocean acidification (OA) is expected to modify the structure and function of coral reef ecosystems by reducing calcification, increasing bioerosion, and altering the physiology of many marine organisms. Much of our understanding of these relationships is based on experiments with static OA treatments, although evidence suggests that the magnitude of diurnal fluctuations in carbonate chemistry may modulate the calcification response to OA. These light-mediated swings in seawater pH are projected to become more extreme with OA, yet their impact on bioerosion remains unknown. We evaluated the influence of diurnal carbonate chemistry variability on the bioerosion rates of two Caribbean sponges: the zooxanthellate Cliona varians and azooxanthellate Cliothosa delitrix. Replicate fragments from multiple colonies of each species were exposed to four precisely controlled pH treatments: contemporary static (8.05 ± 0.00; mean pH ± diurnal pH oscillation), contemporary variable (8.05 ± 0.10), future OA static (7.80 ± 0.00), and future OA variable (7.80 ± 0.10)…
Outreach Partnerships
Coral City Camera
In collaboration with Coral Morphologic, a coral-themed art studio based in Miami, we have assisted in the deployment of the Coral City Camera (CCC), an underwater camera streaming live from an urban coral reef in Miami, Florida. The CCC is a public art and scientific research project led primarily by Coral Morphologic, and produced with Bridge Initiative and Bas Fisher Invitational.
