Nicolas Hahn is an Argentinean photographer dedicated to capturing the beauty and perils of the marine world, as well as communicating humanity’s complex relationship with nature.

His work has been published in National Geographic Magazine and awarded the Save Our Seas Ocean Storytelling Photography Grant (2023), as well as in competitions such as Underwater Photographer of the Year (2021, 2022, 2026), Ocean Photographer of the Year (2022, 2024), the United Nations World Oceans Day Competition, and more.

In his early twenties, Nicolas worked in the diving industry, where he witnessed how the increasingly severe El Niño phenomenon caused widespread heat stress and death on coral reefs, offering a clear glimpse into the decline of ocean health and the approaching climate crisis.

After honing his diving skills in Southeast Asia, Nicolas picked up a camera to better appreciate and document the underwater world he was witnessing. Photography quickly became a rewarding way to express himself artistically, as well as to communicate what he was witnessing underwater.

With a desire to solidify his path as a photographer and focus his lens on conservation issues, Nicolas applied for the Save Our Seas Foundation’s 2023 Ocean Storytelling Photography Grant, which he won. This led to his first photographic assignment, documenting the little documented waters and fishing markets of Angola.

Now, after years of working far from home, Nicolas is turning his camera toward South America, where he is working on his long term project, Austral Waters, exploring environmental stories from the waters of Argentina, Uruguay, and Chile.
