A team of coral researchers from the National Oceanic & Atmospheric Administration (NOAA) and the University of Miami (UM) rescued 43 coral colonies after a sea wall collapsed at Star Island, near Miami Beach. The rapid coral rescue effort occurred at one of NOAA’s regularly monitored research sites. While conducting a routine survey, scientists from […]
In a recent study published in the journal Coral Reefs, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) found that staghorn coral (Acropora cervicornis) fragments exposed to an oscillating temperature treatment were better able to respond to heat stress caused by warming oceans.
MIAMI—A new study found that seafloor sediments have the potential to transmit a deadly pathogen to local corals and hypothesizes that sediments have played a role in the persistence of a devastating coral disease outbreak throughout Florida and the Caribbean.
Trying to predict how coral reefs will respond to warming oceans and a changing climate may be considered a daunting task for scientists. In the face of this challenge, scientists at AOML recently published a study that characterizes the organisms and processes that lead to coral reef accretion (build up) and bioerosion (break down) in the dynamic environments of the Gulf of Panama and Gulf of Chiriqui in the eastern Pacific.
When we look at the state of corals globally, it can be difficult to see a silver lining, but a recent paper published in Frontiers in Marine Science shows hope for corals in unlikely places. In the study, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) at the University of Miami Rosenstiel School of Marine and Atmospheric Science compared the molecular processes of brain corals (Pseudodiploria strigosa) living in urban waters at the Port of Miami with offshore corals at Emerald Reef. They found the urban corals had adapted to challenging conditions that helped them differentiate and consume healthy food particles over diseased organisms.
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.
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.
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.
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.
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.
