The World’s Largest Shark Sanctuary

To state it simply, sharks are interesting. So much so that entire weeks of television are devoted to them. There are a variety of sharks found around the world from the docile wobbegong to the great white shark.

The Largest Shark Sanctuary in the World

The atolls of Tuamotu, especially Fakarava, are world renowned for their shark diving and this means we have been seeing reef sharks on pretty much every dive. In fact, French Polynesia has the world’s largest shark sanctuary at 4.7 million square kilometers. The three most common species of shark we have been seeing are the white tip, black tip and grey reef shark. These are harmless sharks that can be up to 2 meters in length.

These sharks are particularly abundant in the channels running in and out of the atolls. In these passes, the strong currents make the waters particularly rich in nutrients, able to support a high abundance and diversity of reef organisms. The southern pass of Fakarava was one dive where the sharks were particularly abundant with over 100 sharks enjoying the currents.

World Oceans Day: Protecting the Ecosystems That Protect Us

This World Oceans Day, the global community is being challenged to think differently about the ocean.

The 2026 World Oceans Day theme, “Reimagine: Beyond the World We Know, A New Relationship With Our Ocean,” invites us to recognize that the ocean is not something distant or separate from our lives. It regulates our climate, supports our economies, provides food for billions of people, and sustains the natural systems that make life on Earth possible.

Few places illustrate this connection more clearly than the coastal ecosystems that protect our shores and support marine life. While coral reefs, mangrove forests, and seagrass meadows are often…

After the Storm: Standing with Our J.A.M.I.N. Family in Jamaica

There are moments in this work that feel heartbreakingly familiar.

Two weeks after we completed our Jamaica Awareness of Mangroves in Nature (J.A.M.I.N.) programming, Hurricane Melissa made landfall. A powerful Category 5 hurricane, Melissa is now tied with Hurricane Allen in 1980 for the strongest winds ever recorded in an Atlantic storm. Like Hurricane Dorian, which devastated The Bahamas in 2019, Melissa will be remembered as one of the strongest hurricanes on record in the region.

For 11 years, the University of the West Indies Discovery Bay Marine Laboratory and William Knibb Memorial High School have been more than program partners. They have welcomed us into their classrooms and labs, shared meals and laughter, and committed themselves to educating their students about mangroves and coastal resilience. These colleagues and students are not distant collaborators. They are family.

And they were hit hard…
