Scientists explain how sunscreen can cause harm to coral reefs

May 17, 2022 - coral reefs, which can be difficult to work with when in the lab. Sea anemones, however, have similar structures to coral reefs, including the same relationship with algae that lives in them.

In their study, the researchers placed 21 sea anemones in test tubes of seawater while they set up lights that mimic the sunlight's full spectrum. Five test tubes were covered with acrylic to absorb the same UV wavelengths with oxybenzone. The anemones were exposed to ...

Be sure to buy biodegradable sunscreen to protect coral reefs

February 07, 2019 - coral reefs, made a disturbing statement. He says sunscreen chemicals that get into the water while people are swimming enter sewage systems when washed off in the shower. Supporting Downs' alarming statement is his team's 2015 study showing how oxybenzone, a chemical common in sunscreens, harms algae that live in corals. Oxybenzone also stunts coral growth. Meanwhile, a 2008 European study stated that sunscreen led to a viral infection in corals, which in turn, promoted ...

Coral reefs thrived in warmer seas – new research debunks climate alarmism

August 25, 2025 -

If you’ve ever wondered why climate alarmists keep screaming about coral reefs dying from "global warming," a bombshell new study just dropped that turns their entire narrative upside down. It turns out that coral reefs didn’t just survive in warmer oceans; they flourished. And not just a little. We’re talking growth rates six times faster than today in seas that were 1–2 C warmer and one to two meters higher than current levels.

So ...

Experts warn heatwaves can cause “significant and severe” damage to coral reefs

July 19, 2023 -

The heatwave has caused sea surface temperatures in Florida to hit their highest levels since satellites started recording ocean data in 1985. (Related: Dangerous heat wave expected to set record highs throughout US South and Southwest.)

And even though temperatures in the area usually soar as the summer sets in, experts are warning that the current situation is more dangerous for coral reefs than ever before as the heatwave hit earlier, and probably for longer, ...

Scientists are “farming” coral reefs in an effort to increase their survival

April 24, 2018 -

However, scientists are taking up the cudgels in the fight to save coral reefs. In the Mote Marine Laboratory in Florida, for instance, corals are grown in nurseries to be "farmed" later on and transplanted – or "outplanted" as they call it – onto degraded reefs.

When people think of corals, the first thing that comes to mind is a thorny structure where many types of fish swim ...

Hurricane Harvey damage continues: Coral reefs are now threatened from the runoff

October 21, 2017 -

Data obtained from the Texas Automated Buoy System, a network of buoys that keep track of the water off the Texas coast and transmit real-time information, has warned of a 10 percent decrease in salinity at buoy five in the Flower Garden Banks coral reefs. In line with this, a team of researchers at the Rice University, the University of Houston-Clear Lake, Texas A&M, and Boston University is set to sail off Galveston to carry out a five-day expedition to the reefs....

Coral reefs in the Lower Florida Keys being destroyed by a mysterious disease

May 24, 2019 -

Researchers from Florida Keys Community College, working with state and federal investigators, discovered the infected corals during a routine dive in Looe Key – south of Big Pine in part of the Florida Keys National Marine Sanctuary – to collect samples. The discovery put in jeopardy the southern end of the world's third largest barrier reef, renowned for its biodiversity. The reef already lost half of its corals over the last two centuries and just emerged from a three-year bleaching ...

Coral resilience defies climate doom: New studies reveal ancient reefs flourished in warmer seas

August 22, 2025 -

For decades, scientists and policymakers have warned that rising sea temperatures and ocean levels spell doom for the world’s coral reefs. Yet emerging research from Indonesia’s ancient reefs and Australia’s Great Barrier Reef (GBR) tells a starkly different story: Corals not only survived but thrived when oceans were significantly warmer and sea levels far higher than today.

A study published this month in Paleoceanography and Paleoclimatology ...

Human fecal bacteria found in coral reefs more than 100 miles off Houston coast

April 21, 2021 -

In particular, they found that runoff from the 2016 Tax Day flood and the 2017 Hurricane Harvey flood carried human waste into the Flower Garden Banks National Marine Sanctuary. The marine protected area is festooned with sponges and corals. It is also home to various creatures, including whale sharks and manta rays.

Adrienne Correa, a marine biologist who was part of the research team, said they've always thought the Flower Garden Banks National Marine Sanctuary was safe ...

Scientists create an autonomous robot that can hunt for lionfish that threaten coral reefs

November 15, 2018 - coral reefs.)Robot submersible uses machine learning to identify and hunt lionfish

WPI researcher Craig Putnam is part of the team that designed the lionfish hunting robot. He said their drone could help resolve the ecological problem of invasive lionfish.

“The goal is to be able to toss the robot over the side of a boat and have it go down to the reef, plot out a course, and begin its search,” he explained. “It needs to set up a search pattern and fly ...

We can prevent shoreline erosion by protecting coral reefs: Restoring them helps protect islands

May 30, 2018 - coral reefs in shoreline positioning; and (3) the design of an artificial reef that will protect the coast. The researchers culled six decades' worth of historical shoreline and climate data and used a wave energy model to understand the role of currently existing reefs and their impact on the local community. These were then collated by researchers and used to construct an artificial reef solution.

"We are able to apply coastal engineering tools and models to support ...

Sunscreens destroy coral reefs by releasing harmful chemicals that disrupt microorganisms found in water

May 08, 2018 -

Diana Slijkerman, an ecologist at Wageningen University and Research in the Netherlands researched on the seawater quality around a dive center on the island of Bonaire in the Caribbean Sea, and found that seawater samples had concentrations of oxybenzone, a UV filter suspected of killing corals. Sunscreens have been suspected carriers of chemicals that harm marine life since 2008. Italian researchers have stated that sunscreen can cause viral infections in corals and "play an ...

Hope for reef fish: Ocean currents bring food to fish populations in damaged coral reefs

September 15, 2019 -

A healthy coral reef produces large amounts of nutrients. They achieve high levels of productivity through several means.

Coral reefs recycle available materials with high efficiency. They also acquire additional nutrients from sources in deeper waters. Finally, they take full advantage of anything produced by their inhabitants.

Their treasure trove of nutrition draws plenty of marine life that lives in tropical waters. Fish account for most of the ...

Researchers create robot fish that can swim right next to real ones in coral reefs

April 27, 2018 -

Dubbed "SoFi," the soft robotic fish is created out of 3D-printed parts and a small number of components that enable it to swim alongside real fish in the ocean independently. It was created by a team from MIT's Computer Science and Artificial Intelligence Laboratory (CSAIL) and has been shown to be able to swim at depths of more than 50 feet for about 40 minutes at once. And it's able to handle ocean currents with ease while taking high-resolution photos as well as videos through ...

Hawaii seeks to ban toxic chemical sunscreens to save the coral reefs from chemical decimation

May 21, 2017 -

The problem has gotten so bad that Senator Will Espero has proposed a state bill that will outlaw the sale of sunscreen that contains octinoxate and oxybenzone. These two ingredients are responsible for many of the problems coral reefs are currently facing, and they enter the water when people who wear sunscreen go swimming, surfing, snorkeling or even take beach showers.

The chemicals cause deformities in coral larvae, preventing them from swimming, settling and ...
