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.

Heat extremes are the number one weather-related cause of death in the United States, prompting the climate community to study the driving forces behind these extreme events to improve their prediction. A new study published in the Journal of Geophysical Research finds an increase in summertime heat wave occurrence over the US Great Plains is linked to a larger than normal tropical Atlantic warm pool.
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.
On December 19th, after nearly six weeks at sea, scientists aboard the NOAA ship Ronald H. Brown returned to land and docked in Praia, Cape Verde, completing the PIRATA (Prediction and Research Moored Array in the Tropical Atlantic) Northeast Extension (PNE) cruise.
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.
AOML scientists and partners from an assortment of universities and Cooperative Institutes successfully completed the most comprehensive ocean acidification sampling of the Gulf of America to date with the conclusion of the fourth Gulf of America Ecosystems and Carbon Cruise, also known as the GOMECC-4 cruise. The research effort aboard the NOAA Ship Ronald H. Brown began out of Key West, Florida on September 13, 2021 with 25 scientists and graduate students aboard. It ended 39 days later on October 21 with a port stop in St. Petersburg, Florida.
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.
A new analysis of heat wave patterns appearing in Nature Climate Change focuses on four regions of the United States where human-caused climate change will ultimately overtake natural variability as the main driver of heat waves. Climate change will drive more frequent and extreme summer heat waves in the Western United States by late 2020’s, the Great Lakes region by mid 2030’s, and in the northern and southern Plains by 2050’s and 2070’s, respectively.
“These are the years that climate change outweighs natural variability as the cause of heat waves in these regions,” said Hosmay Lopez, a meteorologist at NOAA’s Atlantic Oceanographic Meteorological Laboratory and the University of Miami’s Rosenstiel School Cooperative Institute for Marine and Atmospheric Studies and lead author of the study. “Without human influence, half of the extreme heat waves projected to occur in the future wouldn’t happen.”
Coral researchers at AOML unveiled a new state of the art experimental laboratory this spring at the University of Miami’s Rosenstiel campus. The new “Experimental Reef Laboratory” will allow NOAA scientists and colleagues to study the molecular mechanisms of coral resiliency. Modeling studies indicate that thermal stress and ocean acidification will worsen in the coming decades. Scientists designed the Experimental Reef Laboratory to study the combined effect of these two threats, and determine if some corals are able to persist in a changing environment.
