Our Mission
Inspiring Some of the Largest Marine Reserves in the World
Pristine Seas has helped create 31 of the largest marine protected areas, covering 6.9 million km² of ocean. These “national parks of the sea” restore marine life while boosting food security, growing economies and building climate resilience.
The ocean is the lung of our planet. Yet less than 3% of its waters are fully protected from damaging activities.
While threats to the ocean put its health at risk, marine protected areas offer hope — proving that when ecosystems have the space to recover, they can bounce back spectacularly.
Pristine Seas works alongside communities to unlock mysteries of the sea, tell stories of resilience, and designate marine reserves that thrive.

Where We Work
Our team has studied and filmed the ocean from the Arctic to the tropical Pacific. Through our expeditions and scientific research, we have helped create 31 marine reserves that harbor ecosystems ranging from vibrant sponge gardens and humpback whale nurseries to underwater amber-colored kelp forests and deep sea hydrothermal vents.
The Global Expedition
In 2023 Pristine Seas launched a bold new conservation effort: The Global Expedition. Our team of scientists, policy experts, and filmmakers will spend the next five years exploring the tropical Pacific aboard the Argo, a 130-foot customized research vessel and filmmaking center, with the goal of supporting communities and governments in their efforts to protect the ocean. The Argo is our modern-day equivalent of Jacques Cousteau’s famous ship Calypso.
