New study indicates Stony Coral Tissue Loss Disease may be inhibited by warmer waters 

Stony Coral Tissue Loss Disease (SCTLD) is the deadliest known coral disease to species with a hard skeleton (i.e., Scleractinians), causing rapidly-expanding, bare lesions to form across a coral’s skeleton until there is no more living tissue.  The pathogen or microbes leading to the spread of this disease have yet to be identified. Yet scientists […]

A new model predicts dynamic seawater chemistry on Florida’s coral reefs 

Water masses move over reefs, seagrass beds, and sandbanks – and as they do, the seawater chemistry changes.  In the Florida Keys, changes in coral reef carbonate chemistry are driven by benthic metabolism, the origin of the water mass, and the connectivity of habitats. A new study from NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) […]

New study demonstrates the impacts of multiple stressors on reef-building corals

In a new study, scientists at AOML and the University of Miami’s Cooperative Institute for Marine and Atmospheric Sciences (CIMAS) demonstrated how some genotypes of the reef-building coral Acropora cervicornis (Staghorn Coral), listed on the Endangered Species Act, proved resilient when exposed to high nutrient levels or disease, but not when the two stressors were […]

Scientists at AOML monitor the impacts of ocean acidification on reefs with new series of buoys 

Diver’s drop over the gunnel. Tanks, weights, divers, and a mesh bag full of tools all descend in emerald waters beneath grey skies. Off the vessel’s bow, a yellow beacon blinks with a red flashing light and a thin data cable stretching to the seafloor, all connected to a suite of sensors twenty feet below […]

Investigating the impacts of climate change on reef-building corals using robotic arms 

Blue lights fill the room. The faint smell of salt emanates throughout the space as wires and tubes intricately suspended over robotic arms move along custom-built tracks over four rows of tanks filled with seawater – and fragments of critically-endangered corals. In the Experimental Reef Lab, scientists at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML) and the Cooperative Institute for Marine and Atmospheric Studies (CIMAS) are investigating how crucial reef-building coral species are affected by the impacts of climate change using a suite of open-source robotic arms designed and built at AOML.

A Bold and Unprecedented New Effort to Tackle the Vast Threats to Marine Ecosystems

NOAA announced $4.2 million in funding awarded to a collaborative project entitled the Florida Regional Ecosystems Stressors Collaborative Assessment (FRESCA), co-led by NOAA’s Atlantic Oceanographic & Meteorological Laboratory (AOML) and the University of Miami, and involving seven different academic and research institutions.

What a Marine Heatwave Means for South Florida

A marine heatwave has spread across the Gulf of America 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.

Building Endurance to Beat the Heat: New Study Preps Corals for Warming Waters

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.
