Still Making Waves: Why Dr Sylvia Earle Remains the Most Powerful Voice in Ocean Conservation

At 90, Dr Sylvia Earle is still diving—and dreaming. In partnership with Rolex, she’s proving that true exploration means preserving the wonder you seek

Few people have changed the way we see the ocean quite like Dr Sylvia Earle. The legendary oceanographer, affectionately dubbed “Her Deepness”, has dedicated her life to understanding and protecting the sea. She has led more than 100 expeditions, spent thousands of hours underwater, and remains one of the most influential voices in marine conservation today.

Earle’s relationship with the ocean began far from the shore— in her childhood backyard pond in New Jersey, where she would spend hours observing fish and tadpoles. That early curiosity evolved into a PhD from Duke University and, soon after, a groundbreaking career beneath the waves. In 1970, Earle made history when she led an all-female team of aquanauts aboard the Tektite II, living and working 50 feet below the surface of the U.S. Virgin Islands. The experience propelled her to international acclaim and cemented her conviction to champion ocean protection.

On her return to dry land, Earle and her team were honoured at the White House—fuelling the oceanographer to use this spotlight to highlight the urgent need to protect marine ecosystems worldwide. Her accolades are as deep as her dives.

A Rolex Testimonee since 1982, Earle has received over hundred national and international honours and awards, including Time magazine’s first “Hero for the Planet”, the National Geographic Hubbard Medal, and honours from the Royal Geographical Society and The Explorers Club. She also served as the first female chief scientist of the U.S. National Oceanic and Atmospheric Administration—all while discovering new marine species and inspiring generations of scientists, explorers, and dreamers.

But Earle’s most ambitious mission began in 2009, when she founded Mission Blue, a global initiative to create a network of Hope Spots—ecologically vital marine areas essential to ocean health. With Rolex’s support since 2014 through its Perpetual Planet Initiative, Mission Blue has expanded from 50 to more than 160 Hope Spots across the world, from the Azores Archipelago to the Galápagos Islands.

At the heart of the programme lies a simple yet powerful idea: empower local communities to protect what’s theirs. “Whether we are explorers or concerned citizens, we must save the planet for future generations,” says Earle.

Her words resonate even more urgently today: just eight per cent of the world’s oceans are protected, despite more than 100 countries pledging to safeguard at least 30 per cent by 2030. It’s a cause Earle pursues with tireless resolve—and one that feels more vital than ever.

At 90 years old, with 34 honorary degrees and lectures delivered in more than 80 countries, Earle stands as both scientist and storyteller—one whose life’s work reminds us that exploration means nothing without preservation.

“All of us, individually and collectively, need to respect nature and take care of it,” she says. “We need to treat the ocean and the rest of our living planet like our lives depend on them—because they do.”

Through the Rolex Perpetual Planet Initiative, her message finds even greater reach. Launched in 2019, the initiative unites more than 30 partners working across three key areas—Oceans; Landscapes; and Science, Health, and Technology—to protect Earth’s fragile balance.

It’s a continuation of Rolex’s century-long legacy of supporting exploration, shifting its focus from discovery to preservation.

And for Earle, the mission continues—to dive deeper, dream bigger, and remind us all that the ocean’s story is, in every way, our own.
