NOAA Scientists Return to Cheeca Rocks, Find Reef Completely Bleached

AOML Communications — Thu, 03 Aug 2023 00:29:14 +0000

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.

What a Marine Heatwave Means for South Florida

AOML Communications — Fri, 14 Jul 2023 19:35:36 +0000

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.

AOML Interns Dive into DNA Extraction and Processing Coral Samples for ‘Omics Analyses

AOML Communications — Mon, 10 Jul 2023 21:57:25 +0000

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).

Four decades of coral research lead to an exciting discovery for tropical pacific corals

AOML Communications — Mon, 06 Mar 2023 21:32:40 +0000

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.

Experts Learn from Coral Disease Outbreak

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.

New study establishes monitoring framework for evaluating reef persistence under climate change and ocean acidification

AOML Communications — Fri, 27 Jan 2023 14:18:41 +0000

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.

Study links spread of deadly coral disease to ship ballast water

AOML Communications — Wed, 23 Nov 2022 01:01:12 +0000

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 […]

River Runoff Creates a Buffer Zone for Ocean Acidification in the Gulf of Mexico

AOML Communications — Tue, 15 Feb 2022 20:19:37 +0000

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.

Habitat Altering Processes Are Uncovered for Reefs in the Eastern Pacific

AOML Communications — Tue, 09 Nov 2021 17:03:41 +0000

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.
