Khaled bin Sultan Living Oceans Foundation
Providing science-based solutions to protect and restore ocean health
Despite the restrictions imposed by the pandemic, 2021 was a truly remarkable year for the Khaled bin Sultan Living Oceans Foundation. After spending ten years in the field circumnavigating the globe in an effort to understand the coral reef crisis, …
“There’s a shark on the line!” The young ladies from Black Girls Dive Foundation (BGDF) squirmed with anticipation and giggled with excitement. As their chaperone, I could feel my own adrenaline surging as we watched the University of Miami (UM) team scurrying around at the back of the boat. The chaperones fitted the first four students with gloves and life vests. Then the students lined up in single file to begin their assigned individual and group tasks. It was time to get to work.
In December, I had the honor of being asked to join our partners at Black Girls Dive Foundation on a shark tagging expedition with the UM Professor Neil Hammerschlag’s Shark Research and Conservation team at Rosenstiel School of Marine and Atmosphere Science. The trip is part of BGDF’s Science, Technology, Robotics, Engineering, Arts and Mathematics with SCUBA (STREAMS) program, which is designed to introduce black girls between the ages of 9 and 17 to a multitude of activities. The Shark Research and Conservation Capstone is a component of the STREAMS program that teaches about the behavioral ecology and conservation of sharks. After completing a series of lecture and lab activities, this part of the program culminates with a field-intensive research expedition: shark tagging.
This guest blog comes from a former KSLOF fellow, Dr. Anderson Mayfield, who joined the foundation on many of our Global Reef Expedition research missions in the Pacific and Indian Oceans. A former student of the renowned coral biologist Dr. Ruth Gates, Dr. Mayfield studies coral health and physiology at NOAA’s AOML Coral Program and at the University of Miami’s Cooperative Institute for Marine and Atmospheric Studies. He continues to publish scientific papers based on data collected on the Global Reef Expedition, including his latest paper, recently published in the journal Oceans.
As a naïve post-doctoral researcher back in 2012, I had an idea that was surely far from novel at the time: corals of far-flung, uninhabited atolls are in better shape than those closer to major human population centers. The logic was that these corals would be under global-scale stressors only (namely those associated with climate change), and not the threats that instead plague reefs close to cities (such as pollution and overfishing).
As a fellow with the Khaled bin Sultan Living Oceans Foundation during their Global Reef Expedition (GRE), I tested this hypothesis by sampling corals from among the most seemingly pristine islands and atolls in the Pacific and Indian Oceans. Although we certainly observed beautiful reefs with high coral cover (see image above) and diversity as well as a plethora of fish —all the visible hallmarks marine biologists look for in ‘healthy’ reefs—the corals themselves told a different story (Mayfield et al., 2017); high cellular stress levels were documented in the vast majority of the many hundreds of corals sampled across the GRE.
Despite looking healthy, the corals were struggling to survive.
These high stress levels do not, in and of themselves, imply that all such sampled corals are not long for this Earth. They do signify, however, that we likely never visited ‘pristine’ reefs during the GRE, despite studying some of the most remote coral reefs on the planet. This is a testament to the wide reach of climate change. This statement may come as a surprise to some, who, like me, assumed that somewhere out there, one might find corals entirely untouched by humankind, but this unfortunately does not appear to be the case.
On the Global Reef Expedition, we prioritized using a collaborative approach to study and map coral reefs by partnering with scientific and local experts in each of the countries we visited. While the scientific team was conducting surveys underwater, we also implemented various outreach and education programs in parallel to improve ocean literacy and inspire the next generation of ocean advocates. The partnerships we formed allowed us to exchange knowledge and learn how local communities were using and managing their marine resources.
One of the biggest take-aways from the GRE was that nearly every community we worked with expressed, and continues to express, the want and need for conservation of their reef systems. Working directly with communities, sharing findings, using our education and outreach programs, and expanding on the current management efforts has proven to be the most successful in conserving the reefs visited on the GRE.
Managing marine resources is a challenge for communities around the globe. On the Global Reef Expedition, we had the opportunity to visit protected and unprotected reefs in both remote locations and those regularly used by humans. The degree of protection varied, but we found that areas with the highest protection had the healthiest reefs.
Marine protected areas (MPAs) are a tool commonly used by governments and communities to manage their marine resources. An MPA can have varying degrees of regulations, including no-take and no-entry where no fishing is allowed and entrance into the park is not permitted, to varying permitted use that regulate the fishing and use practices. Some of the countries we visited, such as Australia (Northern Great Barrier Reef), Palau, and New Caledonia have large human populations utilizing the reefs and have prioritized establishing large protected and managed areas to conserve their nearshore reef systems.

Coral reefs are in crisis. Corals are an ancient life form and, because of the reefs that they build, the survival of countless other organisms is predicated on healthy coral ecosystems. But coral reefs are dying at an alarming rate. …
Having first visited the Chagos Archipelago in 2006, it was an immense pleasure to return with the Khaled bin Sultan Living Oceans Foundation under the auspices of the Global Reef Expedition. Returning to the archipelago offered the chance to continue work that had been initiated nearly a decade earlier by other scientists—monitoring of the fish assemblages and health of the coral—but also begin new science initiatives.
Following the discovery of a rich portfolio of vintage aerial photographs for the Chagos Archipelago taken in 1963, we are examining the dynamics of the coastlines of the many islands in the archipelago in an effort to understand how low-lying atoll islands respond to rising sea level. Largely uninhabited, Chagos is one of very few places in the world where the behavior of islands can be tracked in the absence of artificial coastline modifications. That is, “natural” island behavior can be quantified.
