A guest post for Scubaverse by Chloe Brown.
Chloe is a graduate from the University of Southampton where she studied for a BSc Oceanography. She started her diving career whilst studying, which led to her current job working for Velaa Private Island in the Maldives. Chloe works together with the resident marine biologist and coral biologist restoring the house reef while conducting new innovative research to improve restoration techniques.
The reality of climate change beneath the waves is more detrimental than the majority are aware. Among all the reefs found across the globe, 50% have been destroyed in recent years in response to anthropogenic stressors. Unfortunately, these beautiful habitats are tucked away and the effects easily go unnoticed, deteriorating further. This is not the case for the diving community who are unfortunately witnessing this rapid decline in corals and marine life. Therefore, multiple restoration efforts worldwide have jumped in to attempt to restore one of the world’s greatest wonders, before it is too late.
Coral restoration initiatives aim to restore the overall health, abundance, and biodiversity improving the reef’s tolerance to external stressors. The process behind this is to utilize the existing corals to clone them and repopulate the reef. The fact these corals are still surviving on the reefs, despite the natural disturbances, indicates strong resilient characteristics that are very valuable to restoration projects. These corals act as “donor colonies” as small fragments are broken off to be grown in nurseries and later transplanted back onto the reef.
Here at Velaa Private Island, we use the floating mid-water nursery set up. These consist of 1,500 corals and we currently have two of these nurseries in place. Our nurseries mainly hold Pocillopora spp. as it is extremely tolerable with a high prevalence rate. We attach the small fragments taken from the donor colonies with monofilament and crimps to the nurseries, where they grow for a year. This nursery is situated at a depth of 8m (anchored at 30m) and located away from the reef. Growing away from the reef reduces predation, moderates competition, and allows depth alterations during warmer months to mitigate bleaching effects. Other key nursery designs are being trialed by other restoration efforts worldwide. These include coral trees, net nurseries, and ex-situ nurseries in laboratories, where the conditions can be monitored and controlled 24 hours a day.
During transplantation, we use marine cement to attach the corals to rocks and other hard surfaces found along the reef. Over time these corals will propagate outwards via asexual reproduction growing over the adhesives securing themselves on to the reef.We have successfully transplanted over 4,500 corals with a 70% survival rate. This has had a great effect on increasing the abundance and diversity of marine life present on the reef.
We have additionally conducted further research into effective ways to restore species diversity, specifically looking at massive species. It was found that massive coral species survive better when the fragments are transplanted directly onto the reef, skipping the nursery phase entirely. The ideal fragment size should be 1-2cm and attached to the substrate 1cm away from its clones, to allow fusion with growth. It was Dr. Vaughn who discovered that massive coral species grow quicker when they are cut into smaller fragments. He also discovered tissue fusion between clones however, his finding was taken from ex-situ experiments. It’s fantastic to see similar results in-situ with all the natural disturbances prevailing. The overall aim of restoration is to rehabilitate the reefs encouraging natural growth and self-sufficiency. We have certainly seen this as there was higher recruitment (coral larvae settlement) number in the transplant sites compared to the untouched degraded sites. Self-generation has been evident.
This is an insight into a few techniques used by restoration projects. Without reef restoration, it is predicted that a complete loss of coral reefs will be seen in the next 30 years, taking away, the home to 25% of all marine life. This signifies the importance of restoration and future conservation measures. To ensure the sustainability of restoration efforts education and awareness need to be conducted. Awareness needs to be ubiquitous as it is not just those living along the coasts who have an impact on the oceans, it’s everyone. People need to be taught about the reality of the ocean to induce a permanent change; otherwise coral reefs will lose the fight against mankind taking the marine life with it.

Frontline workers honoured with free dive trip to Yap
The remote island of Yap in the Federated States of Micronesia is among the few places in the world that remains free of Covid-19 thanks to its ocean border and a strict travel ban that has kept its residents safe.
Nonetheless, Yap has been affected, too. As one of the world’s premier, award-winning destinations for divers, this paradisiacal location in the western Pacific Ocean has had no outside visitors to its rich shores and reef for nearly a year. But while there may be no virus, the island hasn’t been cut off from the economic impact experienced around the globe.
That didn’t stop Bill Acker, CEO and founder of the Manta Ray Bay Resort and Yap Divers, from doing something, though.
Last March, soon after the island went into lockdown, Bill began to realize the effect of the virus on daily life beyond the island. “Yes, we are closed, have no divers, had to send our employees home and prepare for difficult times,” he said. “But we’re lucky in that we have, for the most part, avoided the human suffering and death this pandemic has caused.”
Thinking about the problems faced by his family business, they paled when he compared them to those endured by the healthcare workers who have been fighting selflessly around the clock for months on end for the well-being and lives of others.
“One evening, while checking the news online, I saw pictures of frontline workers who were tending to desperately ill and dying people when families and friends could not be with their loved ones. It was heartbreaking,” he added.
The next day, a meeting was held with the resort’s staff and Bill invited suggestions for ways they could do something to honor healthcare workers. The result was the idea to award twenty divers who are working on the frontline to save other’s lives during this pandemic while risking their own, with a free week at the resort.
Divers around the world who had been guests at Manta Ray Bay in the past were invited to submit the names of candidates for the award by December 31, 2020. “We received nominations for 126 individuals from as far away as Germany, the U.S., Australia and Canada,” he said. “It was not easy choosing the winners but our committee of staff members took on the job and selected the 20 finalists.”
“While trying to choose the people to reward for their hard work during this Covid-19 crisis,” Bill added, “by reading the nominations we saw that every one of the nominees was doing things above and beyond the call of duty. Sadly, we don’t have the finances to offer over 100 free weeks in Yap, but we do want to recognize the contributions all of them are making to our world. So, we are offering the rest of the nominees a free week of diving in Yap which includes room, hotel tax, airport transfers, breakfast, diving and Wi-Fi. The only requirement is that they travel with at least three other people and stay in two rooms or more.”
“We do not yet know when Yap will open its borders,” said Bill, “but when it does, we will welcome these important guests to Yap to relax and dive with the manta rays and the other beautiful denizens of the ocean surrounding our island home. They are the true heroes of this devastating, historic time and we look forward to honoring them with a well-deserved dive vacation.”
Watch out for our exclusive trip report from a healthcare worker from the UK who is one of the 20 to have been awarded this amazing dive trip!

Dream Dive Locker Build Out. Part I: Demolition (Watch Video)
It’s finally here! Time to start building the greatest dive locker the world has ever seen! Part I: Demolition! #dreamdivelocker
This is the first of a series of videos showing the evolution of building out my dream dive locker. My dream dive locker needs to be dive gear drying and storage, dry storage, workshop, office, editing suite, You Tube studio and classroom. That’s a lot of functions for a small space!
The first step is planning out the space and demolishing the laminate flooring. Then I taped up the walls to get a feel for the space. We have a lot of work to do!
But finally we will have a purpose built space to house all of our dive equipment! Subscribe to our channel to follow our progress!
Thanks for watching, Team!
