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.

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.

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

AOML Communications — Fri, 25 Mar 2022 15:06:09 +0000

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.

Heat Tolerant Corals May Be the Key to Improving Restoration Efforts

AOML Communications — Mon, 17 May 2021 18:05:13 +0000

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.

New Experimental Tool Has the Potential to Improve Restoration Efforts for Coral Reefs

AOML Communications — Mon, 17 May 2021 17:55:01 +0000

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.

UN Environment Programme 2020 Projections of Future Coral Bleaching Conditions

AOML Communications — Mon, 16 Nov 2020 19:36:00 +0000

Recently the UN Environment Programme Report on coral bleaching projections for 2020 was published, updating work that was done in 2017 using a previous generation of global climate models to project coral reef bleaching globally. The report shows some interesting new results. Ruben van Hooidonk, a coral researcher at AOML and the University of Miami Rosenstiel School Cooperative Institute for Marine and Atmospheric Studies, was the lead author of the report.

AOML and SEFSC Researchers Embark on a New Collaborative Effort to Understand the Impacts of Climate on Economically Important Fish Species

AOML Communications — Fri, 23 Oct 2020 18:24:45 +0000

NOAA’s Modeling, Analysis, Predictions, and Projections (MAPP) program is funding a new collaborative project between the Atlantic Oceanographic and Meteorological Laboratory (AOML) and the Southeast Fisheries Science Center (SEFSC) to understand how a changing climate might be influencing commercially important fish stocks. This project will identify key climate and oceanic processes that affect the biology and chemistry of the ocean of relevance to the coastal open ocean species in the U.S. Gulf of Mexico and South Atlantic Bight, managed by NOAA Fisheries and the regional Fishery Management Councils.

Moonlit coral spawning event will shed light on coral resilience in the Florida Keys

NOAA Research — Tue, 27 Aug 2019 16:44:20 +0000

Last week AOML and CIMAS coral researchers, Graham Kolodziej, Anderson Mayfield, and Derek Manzello, entered the ocean off of the Upper Florida Keys to collect tiny floating balls being released from the protected mountainous star coral (Orbicella faveolata). Taking place shortly after moonrise, the spawning process is a visually beautiful part of the circle of life for corals, releasing gametes into the ocean water to become fertilized and eventually settle to create new corals stony coral colonies.
