Reef Balls and Eternal Reefs Create New Habitats for Animals of the Sea

The Ocean’s Forests

John and Patricia Hanson pre-paid and left instructions for their children to place their ashes together in an Eternal Reef when they passed. The couple had retired to Panama City and later moved to Foley, Alabama. Hanson was a merchant mariner before joining the U.S. Coast Guard and retired as a captain. Last fall, their wishes to combine their nautical heritage with a lasting positive effect on the ocean were realized with their own Reef Ball placed off the Pensacola coast.

“It was definitely an unusual circumstance. These days, the way our society is, death is kept at arm’s length,” said John Hanson II, the couple’s son, who participated in the mixing of his parents’ ashes into the concrete reef module. He said the family received much-needed closure from this opportunity to gather together for this memorial. “It was a positive undertaking in terms of reef building and contributing to the betterment of our environment.”

Hanson laughed remembering how, on the day the family scheduled to take the boat off shore to watch their reef placement, remnants of a storm called Patricia (like his mother) made the Gulf of Mexico too rough, preventing them from going.

“My mother’s last gasp at making things difficult,” he said. “She was OK with it.” 

Over three-quarters of a million Reef Balls, placed in 70 countries and many off coastal states of the United States, contribute to coral growth, estuary and reef restoration and sustainable marine reef habitats. Eternal Reefs are located off the coasts of Florida (on both the Atlantic and Gulf coasts), Texas, South and North Carolina, Virginia, Maryland and New Jersey. Family and friends are encouraged to participate in the casting. The four-day process includes mixing the ashes into the concrete mixture placed on the reef. The top of the reef can be personalized with handprints, inscribed messages and seashells. The Eternal Reef placements are in permitted sites, designated for development as recreational reefs for fishing and diving. The dedication ceremony includes a chartered boat taking families to the site where the reefs are placed from a nearby boat.

Even with these initiatives, more help is needed for corals. Corals are animals with tiny, tentacle-like arms for capturing food from the water. They permanently attach themselves to the ocean floor, forming coral reefs, supporting and sustaining the sensitive marine ecosystems surrounding them.

“Sadly, coral reefs are declining all over the world,” said Michael Webster, a coral reef scientist and executive director of the Coral Reef Alliance (CORAL), which partners with communities and individuals living near reefs to reduce threats. “The biggest problem is that the corals themselves are disappearing. Corals build the reef. It would be like if trees made mountains. The corals make the rock, which builds up into a reef.”

The causes of coral decline are varied, Webster says, and include overfishing, unsustainable tourism, pollution, ocean warming and some direct destruction of the reefs. He mentioned that China’s island building in the South China Sea has damaged coral reefs. In addition, carbon dioxide released in the atmosphere and absorbed in the ocean contributes to ocean acidification and coral demise.

“In most places where there are reefs, I would argue we need to stop killing them,” he said. “There are a whole lot of reasons to care, whether that’s tourism or fishing, protecting the coastlines from storms, and it looks like a lot of the medicines for the future are coming from reefs as well. We don’t have that much time to sort this one out. We have to figure out how to live with coral reefs over the next century … It takes time for plants and animals to adapt to these changes.”

The solution? Solve the local problem so corals can return. Webster supports building an artificial reef where it makes sense. He recommends providing a new place for corals to grow, maybe sandy areas that can support an artificial reef.

“Allow people to fish those and leave the natural reef alone,” he said. “Everybody wins, including the corals.”

Todd Barber is fond of using an analogy when he talks about winning one for the corals.

“When we plant coral on artificial reefs, it’s not much different than planting in your backyard … If you destroy a forest, you have to replant it,” he said. “We’re planting with corals instead of grass and trees. People just don’t realize it because they don’t see it.”

While the process of growing Reef Balls into a living reef system takes about five years, for Barber, that’s not too long to wait. One of his proudest projects was in Antigua, where his team put in 3,200 Reef Balls, planted more than 10,000 corals and rescued another 5,000 corals from the path of a dredge. Today, it is a natural reef system and national park.

“It was my dream job,” he said. “Of course, for me, my heart is still in the Cayman Islands … It’s why I started this thing in the first place.” 


On the ball for coral reef rescue

The artificial reef dome, called a Reef Ball, has a hole on top to prevent the lifting effects of a hurricane-force sea state, with thicker bottom walls and thinner top walls.

Other enhancements have been made to accommodate the coral from lessons learned by teams making the module in Mexico. For example, corals are animals that, early in their development, seek to live in grooves and attach to rough textures. The texture of the Reef Ball was roughened, and more holes were cut around the mold to create whirlpools to work with the ocean currents flowing by, carrying nutrients to feed the corals.

Reef balls come in a variety of sizes for a variety of places. In about an hour, an average Reef Ball of 4 feet tall, 3 feet wide and 1,500 pounds can be made with $100 of materials.
