Characterizing Coral Resilience in the Anthropocene: A Reef in the “New Normal”

It can be hard to stay upbeat as a marine biologist, especially with the onslaught of existential threats like climate change facing the planet. Coral reefs are arguably the ecosystem that stands to lose the most with respect to climate change, namely because the resident organisms are highly sensitive to elevated temperatures. Furthermore, the limestone-based reef framework itself is diminishing before our eyes due to the accompanying rise in carbon dioxide levels (which decreases oceanic pH, leading to ocean acidification). That being said, there are corals out there that display resilience, continuing to thrive in habitats that would appear decidedly marginalized to even the untrained eye.

Scientists at AOML Present Coral Research at the First Virtual International Coral Reef Symposium

Coral scientists at NOAA’s Atlantic Oceanographic Meteorological Laboratory (AOML) and the University of Miami Rosenstiel School’s Cooperative Institute for Marine and Atmospheric Studies (CIMAS) will be presenting their research at the 14th International Coral Reef Symposium (ICRS) from July 19-23, 2021, which will be held virtually for the first time in the history of the ICRS.

Coral Growth in Flower Garden Banks Approaches Threshold As Sea Temperatures Rise

A recent study by researchers at NOAA’s Atlantic Oceanographic and Meteorological Laboratory shows that coral growth observed in symmetrical brain corals (Pseudodiploria strigosa) and mountainous star corals (Orbicella faveolata) in the Flower Garden Banks reefs, in the Gulf of Mexico, are linked to warming sea surface temperatures.

Heat Tolerant Corals May Be the Key to Improving Restoration Efforts

A new study by researchers at the University of Miami’s Rosenstiel School of Marine and Atmospheric Science and NOAA’s Atlantic Oceanographic and Meteorological Laboratory suggests that outplanting corals, specifically staghorn coral (Acropora cervicornis) from higher temperature waters to cooler waters, may be a better strategy to help corals recover from certain stressors. The researchers found that corals from reefs with higher average water temperatures showed greater healing than corals from cooler waters when exposed to heat stress.

New Experimental Tool Has the Potential to Improve Restoration Efforts for Coral Reefs

To help improve the long term survival of nursery raised staghorn coral (Acropora cervicornis), Ruben van Hooidonk, a coral scientist with NOAA’s Atlantic Oceanographic and Meteorological Laboratory and the Cooperative Institute for Marine and Atmospheric Studies has developed a new experimental mapping tool i that ranks suitable outplant locations. There are currently at least seven coral nurseries in Florida that cultivate staghorn coral, representing one of the best opportunities to maintain resilient populations of this species.

Two Bacteria Types Linked With Stony Coral Tissue Loss Disease Hint At How This Deadly Disease Might Spread

New research on stony coral tissue loss disease reveals similar “bacterial signatures” among sick corals and nearby water and sediments for the first time. Results hint at how this deadly disease might spread, and which bacteria are associated with it, on Florida’s Coral Reef.

Location, Location, Location: How Habitat and Microbiomes May Contribute to Coral Outplant Success

A new study by coral researchers from the University of Miami’s Cooperative Institute for Marine and Atmospheric Studies (CIMAS) and NOAA’s Atlantic Oceanographic and Meteorological Laboratory suggests that the physical oceanographic habitat characteristics-such as, temperature, light availability, and water flow, of corals, may influence microbe communities and health of coral reefs.  The results showed a link between physical habitat and coral microbiology in coral reefs in southeast Florida.

Moonlit coral spawning event will shed light on coral resilience in the Florida Keys

Last week AOML and CIMAS coral researchers, Graham Kolodziej, Anderson Mayfield, and Derek Manzello, entered the ocean off of the Upper Florida Keys to collect tiny floating balls being released from the protected mountainous star coral (Orbicella faveolata). Taking place shortly after moonrise, the spawning process is a visually beautiful part of the circle of life for corals, releasing gametes into the ocean water to become fertilized and eventually settle to create new corals stony coral colonies.

Scientists Use 3D Printing Technology to Study Water Chemistry at Coral Reefs

AOML researchers have taken an innovative approach to studying the changing carbonate chemistry of seawater at shallow coral reef sites. Using 3D printing technology made possible by the new Advanced Manufacturing and Design Lab at AOML, researchers with the Acidification, Climate, and Coral Reef Ecosystems Team, or ACCRETE, have created a water sampler in-house.

Coral Reefs will be Unable to Keep Pace with Sea-Level Rise

NOAA contributed to a study published today in the journal Nature that compares the upward growth rates of coral reefs with predicted rates of sea-level rise and found many reefs would be submerged in water so deep it will hamper their growth and survival. The study was done by an international team of scientists led by the University of Exeter in the United Kingdom.
