The ocean has always been more than blue; it is myth and mirror, memory and mystery. And once a year, the UN World Ocean Day Photo Contest reminds us why. The 2025 edition, organized by the United Nations Division for Ocean Affairs and the Law of the Sea in collaboration with DivePhotoGuide, Oceanic Global, and UNESCO’s Intergovernmental Oceanographic Commission, delivered a visual symphony of ecological splendor and human awe.

This year’s theme, “Wonder: Sustaining What Sustains Us,” invited photographers to peer into the soul of the sea. The results? Fifteen haunting, sublime, and urgent portraits of our watery world—each one a testament to fragile beauty and the visceral need to protect it.

The Eye of a Whale and the Memory of the Deep

Topping the Wonder category is Rachel Moore’s intimate photograph of a whale’s eye—an image that feels less like a photo and more like a conversation with the sublime. It’s not spectacle. It’s presence. A gaze that collapses centuries, continents, and the crust of language itself.

Close behind is Steven Lopez’s golden-lit image of a Caribbean reef shark in Cuba’s Jardines de la Reina. Sharks blur into abstraction, gliding through liquid gold like brushstrokes on a moving canvas. The message? Abundance is still possible—if we protect it.

Geometries of the Deep: Underwater Seascapes

Gerald Rambert’s second-place entry in the Underwater Seascapes category shows a school of rays at a cleaning station in Mauritius. Once a common sight, now a vanishing one. The coral bleaching that followed reveals more than ecological crisis—it reveals our own denial.

In Pedro Carrillo’s third-place shot from Tenerife, massive basalt columns—formed by millennia-old lava flows—rise like the ruined organs of a submerged cathedral. It’s geology masquerading as architecture, a place both sacred and alien.

Honorable mention goes to Lars von Ritter Zahony, whose split-shot of a leopard seal hunting near a gentoo penguin colony is a cinematic study in tension. Predator below, colony above—each breath taken feels borrowed.

Earthbound Majesty: Above Water Seascapes

Leander Nardin’s winning image in this category captures a remote lake in Western Australia from the sky—dunes and water in a yin-yang of elemental contrast. It’s landscape not as terrain, but as testimony. The ocean doesn’t end at the shore; it continues in every vein of freshwater that pulses inland.

Nur Tucker’s photograph of gannets in flight over Scotland’s Hermaness cliffs slices the sky with avian precision. Wind-torn and wing-born, it is the choreography of instinct set against the drama of geology.

And then there’s Andrey Nosik’s sublime reflection of the Suárez Glacier in Antarctica, taken from a speedboat’s belly. Motion meets stillness. Ice meets soul.

When Art Becomes Advocacy

It’s easy to romanticize ocean photography—to aestheticize the very thing we’re in danger of losing. But what makes these fifteen images exceptional is their refusal to be passive. Each one contains a friction between wonder and warning, spectacle and silence.

Take Ollie Clarke’s breathtaking encounter with two humpbacks at Ningaloo Reef. The whales aren’t fleeing—they’re approaching. Curious. Confident. And deeply vulnerable. Clarke’s breathless testimony reminds us: we are not separate from the ocean; we are constantly observed by it.

The Image as Witness

At the UN Ocean Conference in Nice, and later at The Explorer’s Club in New York, these photographs stood not as mere decoration but as emissaries. They said what treaties often fail to: that the ocean is not a place but a living presence, and one that watches, remembers, and—if we’re lucky—invites us back.

The 2025 UN World Ocean Day Photo Contest may have crowned winners, but it offered something rarer: a reframing of the ocean not as a backdrop, but as a protagonist. A body with memory, breath, and boundless capacity for beauty—and loss.

To look at these images is to ask, what will the ocean see next? And more importantly, will we still be here to witness it with wonder?
