Proposal To Protect Pacific Corals Exempts Military Training Areas

February 18, 2021 — A National Marine Fisheries Service proposal to designate 230 square miles of critical habitat for seven threatened coral species in the Pacific Ocean is getting mixed reviews from environmental advocates due to an exemption for military training areas.

The unprecedented initiative would be a milestone for groups fighting to preserve the coral species, which are threatened by warming seas and ocean acidification fueled by climate change. But critics say the military should have to adhere to the same rules and called for more public hearings before a decision is made.

The designated critical habitats are located in American Samoa, Guam, the Northern Mariana Islands and other U.S. Pacific islands.

“The proposal does not accurately reflect the cumulative impacts of the proposed federal activities that will take place in the area that may affect the survival of these coral species,” Guam Sen. Sabina Flores Perez said in her public testimony on the proposal.

Feds triple the size of the Gulf of Mexico’s largest coral sanctuary

January 20, 2021 — The Gulf of Mexico’s largest coral sanctuary just got a lot bigger.

The federal government on Tuesday formally approved the expansion of the Flower Garden Banks National Marine Sanctuary, increasing its size from 56 square miles to 160 square miles.

Tripling the sanctuary’s size will better protect fragile coral reefs that support a variety of fish and other marine life off the coasts of Louisiana and Texas, said G.P. Schmahl, the sanctuary’s superintendent.

“From an economic point of view, it’s critical for fish that are important both recreationally and commercially,” he said, noting the abundance of red snapper, grouper and mackerel in the sanctuary. “If you fish the Gulf of Mexico, these areas are where the fish you want to catch have spawned and grown.”

The expansion “has been a long haul,” Schmahl said. Initially proposed under the administration of President George W. Bush and formalized under President Barack Obama, the process finally concluded concluded during the final week of President Donald Trump’s administration.

U.S. coral reefs’ health assessed for the first time on a national scale

November 11, 2020 — The following was released by NOAA:

Coral reefs in both the Pacific and Atlantic oceans received a “fair” score in the first-ever condition status report for U.S. coral reefs released by NOAA and the University of Maryland Center for Environmental Science (UMCES) today. While the overall scores were “fair,” the report highlights coral reefs are vulnerable and declining. This is the first time coral reefs in all U.S. states and territories have been assessed using standardized monitoring data, creating datasets that offer a baseline of coral health on a national scale.

The U.S. Coral Reef Condition Status Report was developed by NOAA’s National Coral Reef Monitoring Program and UMCES’s Integration and Application Networkoffsite link using data collected between 2012 and 2018. The scores are denoted as “very good,” “good,” “fair,” “impaired,” and “critical.” The report was based on four categories when assigning a score: corals and algae abundance, reef fish populations, influence of climate on coral reefs, and human connections to reefs.

“Considering the more than $3.4 billion in annual economic benefits of coral reefs, these reports and the policy actions that they will inform are critical to our American Blue Economy,” said retired Navy Rear Adm. Tim Gallaudet, Ph.D., assistant secretary of commerce for oceans and atmosphere and deputy NOAA administrator.

Coral reefs near higher density human populations are degraded, which is likely due to local stressors including land-based sources of pollution and damaging impacts from fishing.

“To conserve and restore coral reefs, we need to understand the overall condition of these  ecosystems,” said Jennifer Koss, director of NOAA’s Coral Reef Conservation Program. “This report represents a snapshot of reef condition and is a great resource for communities and decision-makers throughout the nation. We hope the report starts a dialogue about the various factors and potential solutions to the threats affecting coral reefs.”

Greatest among the threats to coral reefs is climate change, according to the report. Warmer, more acidic seawater is negatively affecting coral reefs globally, no matter how remote they are.

“These status reports clearly show the impacts people are having on coral reef ecosystems,” said Heath Kelsey, director of UMCES’s Integration and Application Network. “Our work in the Pacific and Atlantic Oceans shows a dire outlook for coral reef ecosystem health, from warming ocean waters, fishing, disease, and pollution from the land. Of all of these, climate change is the single biggest threat to shallow water coral reefs in the U.S., and worldwide.”

‘Like Christmas in October.’ Deep-sea corals get new protections in the Gulf of Mexico

October 19, 2020 — The federal government has approved new protections for 500 square miles of deep-sea coral habitat in the Gulf of Mexico.

The protected areas are scattered across 13 reef and canyon sites from Texas to the Florida Keys that support an abundance of sea life, including snapper, grouper and other fish favored by commercial and recreational fishers.

The rules, approved Thursday (Oct. 15) by the National Oceanic and Atmospheric Administration, prohibit fishing with bottom tending nets and other gear, which can rip apart corals that have lived for hundreds of years.

The environmental group Oceana has pushed for the protections for some 20 years.

“We’ve been waiting a long time for this,” said Gib Brogan, an Oceana campaign manager. “It’s like Christmas in October.”

Deep-sea corals, like their shallow and warm-water cousins, are actually colonies of small animals that build a common skeleton. But unlike tropical reef corals, deep-sea varieties live in cold, dark depths of up to 10,000 feet. Deep-sea corals form into tree, feather and fan shapes that host a variety of other species, including shrimp, crab and fish.

Deep beneath the high seas, researchers find rich coral oases

September 15, 2020 — Aiming to bolster conservation on the high seas, a team of marine researchers today released the first comprehensive survey of coral reefs in the high seas–the roughly two-thirds of the ocean outside of national jurisdictions.

After combing through more than half a million observations of reef-building corals, the team identified 116 reefs located in the high seas. Most of these corals live between 200 and 1200 meters beneath the surface, the researchers found. But a handful are found more than 2 kilometers deep. And there are likely many more high seas corals still to be found, the authors note, as surveys have typically prioritized corals close to shore.

The study coincides with the launch of the Coral Reefs on the High Seas Coalition, a group of scientists and nonprofits that aims to support research cruises to survey the steep, deep-water slopes where many of the reefs sit. Eventually, the coalition hopes the data will help persuade policymakers to give these poorly understood ecosystems greater protection in global agreements currently under negotiation.

“Some of the first marine protected areas were specifically designed around coral reefs. … So much literature suggests these are the rainforests of the seas,” says co-author Daniel Wagner, the coalition’s coordinator and an ocean technical adviser at Conservation International. The coalition of nonprofits hopes to influence implementation of a United Nations pact, the Intergovernmental Conference on Marine Biodiversity of Areas Beyond National Jurisdiction, which is expected to set rules for establishing marine preserves on the high seas. (A final meeting of the negotiators set for earlier this year was postponed because of the COVID-19 pandemic.)

UNCW Researchers Spawn Endangered Coral

August 25, 2020 — A University of North Carolina at Wilmington laboratory made history this month by spawning in captivity an endangered coral that once thrived in shallow reefs in the Caribbean.

Researchers at the university’s Center for Marine Science are the first to spawn two species of coral, including Orbicella faveolata, also known as mountainous star coral, in a laboratory.

Their success at reproducing the coral stems from a groundbreaking discovery just a few years ago in the United Kingdom, where a then-doctorate student collaborated with Neptune Systems, a company that makes aquarium controller systems, to electronically mimic environmental settings coral rely on in the wild to spawn.

“Ever since then other institutions and other laboratories have been able to do so,” said Nicole Fogarty, the assistant professor who headed the research in the lab referred to as the Spawning and Experimentation of Anthropogenic Stressors, or SEAS facility. “This has just been a big game-changer in trying to spawn corals in technology.”

Aggressive new seaweed is killing coral reefs in remote Hawaiian island chain

July 8, 2020 — Researchers say a recently discovered species of seaweed is killing large patches of coral on once-pristine reefs in the Northwestern Hawaiian Islands and is rapidly spreading across one of the most remote and protected ocean environments on Earth.

A study from the University of Hawaii and others says the seaweed is spreading more rapidly than anything they’ve seen before in the Northwestern Hawaiian Islands, a nature reserve that stretches more than 1,300 miles north of the main Hawaiian Islands.

The study was published Tuesday in the journal PLOS ONE.

The algae easily breaks off and rolls across the ocean floor like tumbleweed, scientists say, covering nearby reefs in thick vegetation that out-competes coral for space, sunlight and nutrients.

In a tiny explosion of birth, coral scientists see hope for endangered reefs

April 23, 2020 — Keri O’Neil almost missed the tiny grains expelled by the ridge cactus coral that she studies at the Florida Aquarium’s Center for Conservation.

The small pellets, measuring just one-eighth of an inch long, were easy to miss against the colorful backdrop of knobby ridges and creases of the unusual species.

“That first day, we weren’t even sure what we were looking at,” said O’Neil, a senior coral scientist at the aquarium.

What O’Neil and her colleagues had witnessed was a ridged cactus coral giving birth.

The scientists say it’s the first time this type of coral — which can look vaguely like a cross between a head of lettuce and a human brain — has reproduced naturally in a lab. The successful births offer hope for conservationists who are racing to save Florida’s endangered coral reefs.

Feds Agree to Consider Protections for Hawaii’s Cauliflower Coral

March 5, 2020 — The Trump administration agreed Wednesday to determine by this summer whether it will extend federal wildlife protections to Hawaii’s cauliflower coral reef.

The agreement, filed in federal court in Honolulu, comes after the Center for Biological Diversity sued claiming the National Marine Fisheries Service fails to protect the coral under the Endangered Species Act.

In its federal complaint, the conservation group said Hawaii’s cauliflower coral has been devastated by ocean warming.

Warming oceans have caused widespread bleaching of the coral, whose populations declined by 36% between 1999 and 2012, according to the conservation group. A global coral-bleaching between 2014 and 2017 killed millions of coral on hundreds of reefs from Hawaii to the Great Barrier Reef off the coast of Australia.

Little Relief in the Deep for Heat-Stressed Corals

January 8, 2020 — The following was released by NOAA Fisheries:

A team of NOAA scientists recently examined more than a thousand hot water events on coral reefs across the Pacific Ocean. Combining on-site monitoring with satellite records, they found that corals in deeper waters are just as exposed to marine heatwaves as those in shallower waters. They published these findings in Nature Scientific Reports.

This is bad news for coral reefs. These unique ecosystems have already experienced the devastating effects of three global coral bleaching events from hotter-than-normal water. Climate models project that temperatures will continue to rise.

“Scientists primarily use satellite-derived sea surface temperatures to understand heat stress and predict coral bleaching,” said Dr. Scott Heron, an associate professor at James Cook University and partner of NOAA. “It’s immediately available, it’s convenient and it has global coverage. However, because the measurement is only at the very surface of the ocean, there is some uncertainty about how well it reflects what is actually happening on deeper reefs.” In fact, the data might be underestimating the stress caused by these higher temperatures.
