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.
A marine heatwave has spread across the Gulf of Mexico and the Caribbean with temperatures ranging between one and three degrees Celsius (~2-4.5˚F) above average. Ocean temperatures around south Florida are the warmest on record for the month of July (dating back to 1981). Marine heatwaves are not unprecedented, but their influence on tropical storm development and coral reef health, as well as the persistence of the current heatwave, are among the causes for concern.
Only a few weeks into summer, Coral Program Interns Lorelei Ing, Taylor Gill, Zachary Zagon and Kenzie Cooke have been hard at work as they process coral samples and perform DNA extractions in preparation for ‘Omics analyses that will help to better understand how the genetic structure of corals influences their resilience to environmental stressors. The Coral Program falls within the Ocean Chemistry and Ecosystems Division (OCED) at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML).
Using a crowdsourcing approach to gather both published and unpublished data, scientists have determined the global bacteria patterns associated with deadly stony coral tissue loss disease (SCTLD).
A heat-tolerant algae found in some tropical Pacific corals can make reefs more resilient to heatwave events, according to a new study in the Proceedings of the National Academy of Sciences. Researchers with University of Miami’s Cooperative Institute for Marine and Atmospheric Studies (UM-CIMAS) and NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) examined four decades of temperature, coral cover, bleaching, mortality data from three mass bleaching events, and symbiont community data from the last two, to find that a symbiont algae helped corals better tolerate heat stress, increasing their resilience to warming ocean temperatures.
When white lesions began appearing at the famously intact Flower Garden Banks coral reef system, scientists knew a rapid, multi-agency, collaborative response was vital. Scientists from NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and University of Miami’s Cooperative Institute of Marine and Atmospheric Studies (CIMAS) recently co-authored a publication about rapid tissue loss on the three dominant coral species at Flower Garden Banks National Marine Sanctuary, observed during National Coral Reef Monitoring Program cruises in the fall of 2022.
Coral scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and University of Miami Cooperative Institute of Marine and Atmospheric Science (CIMAS) developed a new modeling approach, for evaluating coral reef persistence under climate change scenarios. Aiming to improve coral restoration efforts, this new user-friendly framework has been created as a helpful tool for coral reef scientists and managers to address the increasing vulnerability of these vital ecosystems.
This story was adapted from an article by the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science. A new study suggests that ships may be spreading a deadly coral disease across Florida and the Caribbean. The findings may help to establish testing and treatment methods to prevent further spread. According to lead […]
A new study by scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and Northern Gulf Institute (NGI) has revealed the alkalinity of river runoff to be a crucial factor for slowing the pace of ocean acidification along the Gulf of Mexico’s northern coast. This valuable, first-time finding may be indicative of ocean carbon chemistry patterns for other U.S. coastal areas significantly connected to rivers.
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.
