Khaled bin Sultan Living Oceans Foundation
Providing science-based solutions to protect and restore ocean health
Our Chief Scientist, Dr. Sam Purkis, will be giving a virtual lecture on January 18th at 7pm ET entitled “Beauty and Peril in the Red Sea.”
Dr. Purkis has joined the Khaled bin Sultan Living Oceans Foundation on many research missions, including several to the Red Sea. We hope you take this opportunity to hear more about his work and learn about the remarkable diversity and resiliency of coral reefs in the Red Sea.
As 2021 comes to a close, the Khaled bin Sultan Living Oceans Foundation is taking some time to reflect on everything we have accomplished this year.
Despite the restrictions imposed by the ongoing pandemic, we have had quite a few things to celebrate. This year we entered into a partnership with NASA to map the world’s reefs, concluded our 10-year Global Reef Expedition, and published a final report of our findings. We also presented our research at two major international conferences: the IUCN World Conservation Congress and the International Coral Reef Symposium (ICRS), released a report of our research in the Chagos Archipelago, and published several peer-reviewed scientific papers.
Our education and outreach departments also had a remarkable year. This year we launched a new mangrove conservation program with our partners in Jamaica and had students from over 60 countries submit artwork to our Science Without Borders Challenge. Last but certainly not least, we produced an excellent TV show on ocean health, “Our Living Oceans,” which is now playing on EarthxTV.
It’s been an incredible year, and we look forward to the work we will accomplish next year to help protect, preserve, and restore our living oceans.
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 subjected to natural and human-induced disturbances, both of which can have a negative impact on the health of the ecosystem. Examples of human caused disturbances include pollution, destructive fishing practices, overharvesting animals for the aquarium trade, among …
On the Global Reef Expedition, our team of scientists assessed the reef fish populations in both fished and remote locations to help identify if reef fish were being overexploited. This type of research is important for the health of the coral reef ecosystem, but also for the people who depend upon them.
An estimated six million fishers in 99 countries and territories target reef fish species for sustenance and subsistence. The world’s reefs produce 10-12% of the fish caught in tropical nations and 20-25% of the fish caught in the developing nations of the Pacific, Indian, Middle East, and the Caribbean. Across the tropical Pacific nations, it is estimated that 90% of the daily protein consumed by local communities comes directly from adjacent reefs. With so many people relying on reef fish for their daily lives, managing fish stocks is imperative.
Some studies suggest minimum reef fish biomass targets should fall between 1,195 and 1,900 kg per ha (or 11-19 kg per 100m2) to help maintain sustainable reef fish populations and help maintain critical ecosystem services, food security, and resilience of coral reefs. In most locations, we found the fish biomass fell at or below this.
Climate change is affecting oceans globally, but many believe coral reefs are the world’s “canary in the coal mine” when it comes to irreversible damage resulting from climate impacts.
To understand the mechanisms of climate change, it is important to look at the history of carbon emissions. In the 1880s, the industrial revolution catalyzed the use of carbon-based fuel and helped advance human civilization in ways very few could imagine. However, one downside to this advancement was the exponential release and trapping of carbon in our atmosphere, usually in the form of carbon dioxide. For the past 140 years, this accumulation has resulted in substantial changes to the Earth’s climate.
The Earth’s ocean is a net carbon sink, meaning it absorbs more carbon than it releases. Within the ocean, there are many chemical changes that can occur as the amount of carbon dioxide is dissolved into the water. One of the most common changes is a decrease in the ocean’s pH as it becomes more acidic as more CO2 is absorbed, a term commonly referred to as ocean acidification (OA). This decrease in pH has led to numerous physiological problems in marine animals, particularly calcifying organisms like those found on coral reefs.
Tune into EarthxTV tonight to watch the season finale of Our Living Oceans!
Our Living Oceans is a documentary series that explores the health of our living oceans, the threats they face, and what is being done to save them through conversations with scientists, conservationists, and local leaders from around the world. The Khaled bin Sultan Living Oceans Foundation is proud to partner with EarthX to produce this remarkable series.
This week’s episode focuses on Ocean Optimism. In it, we share success stories of ocean conservation and the hope we have for preserving our oceans for the use and enjoyment of current and future generations. This episode features the renowned marine biologist and coral conservationist Dr. Nancy Knowlton, one of the founders of the #OceanOptimism movement. She talks about what gives her hope for our ocean’s future. This episode also features Her Deepness, Dr. Sylvia Earle, talking about how a TED prize made it possible for her to launch Mission Blue and create a global network of Hope Spots to help protect our living oceans. The season finale also includes our Education Director, Amy Heemsoth, who discusses the education and outreach work we did on the Global Reef Expedition and how the Living Oceans Foundation continues to inspire the next generation of ocean advocates.
Coral reefs are majestic undersea wonders that contain some of the most unique and mysterious creatures I have ever observed. Ever since my first encounter with one while snorkeling, the natural awe and intrigue I feel in the presence of these incredible ecosystems has never left me. Throughout my education I have learned about the biology, the functions, and the benefits of coral reefs, and the natural and anthropogenic activities that threaten them. But it wasn’t until I started teaching about coral reefs on the Global Reef Expedition (GRE) that I truly understood the interconnectedness between people and the reefs. It was an insight gained not through a textbook, but, rather, from listening to, speaking with, and directly engaging those whose lives—and livelihoods—are impacted by coral reefs.
During the GRE Fiji mission, we launched our first large-scale education and outreach program that coincided with the scientific research taking place. Before we could proceed, however, we first needed to meet with the chiefs of the local villages to discuss our scientific and educational objectives, as well as seek their approval to continue in our mission. With the helpful guidance of our local liaisons and education partners, Roko Josefa Cinavilakeba and Laitia Raloa, we were able to have fruitful discussions with the chiefs of each village, after which the science team was granted permission to continue in their research. The education team, after continued discussions with the chief and other community members, were able to establish a schedule for coral reef education seminars for the schools and local communities.
Published in Frontiers in Marine Science Abstract Empirical methods for estimating shallow-water bathymetry using passive multispectral satellite imagery are robust and globally applicable, in theory, but they require copious local measurements of water depth for algorithm calibration. Such calibration data have …
