Problem

90% of coral reefs could disappear by 2050. Most restoration fails within 3 years. Let’s change that.

50%

Of coral reefs have been lost in the past 50 years.

63%

Of reef biodiversity lost due to collapse and degradation.

Half of the world's corals are dead.
Let's do something about it.

SOLUTION

ARKs

  • Modular, midwater ecosystems
  • 100K ARKs can restore ~280 hectares of reef, an area larger than the country of Monaco

ARMs

  • LEGO-like blocks that recruit biodiversity from viruses to invertebrates
  • 100K ARMs can preserve 85% of global reef biodiversity

Our Projects

“Coral ARKs are restoring reefs at scale. Our projects span diverse ocean environments, demonstrating how modular reef platforms can rebuild biodiversity, protect coastlines, and empower local communities. Each Ark serves as a living laboratory, advancing restoration science and proving that coral recovery can be both scalable and sustainable.”

Global ARK Locations

What Sets Us Apart

Inspired by nature, built for resilience.

Each Ark is engineered using biomimicry, 3D geometry, and reef-safe materials to recreate the complexity of natural coral reefs.

Placed where reefs thrive best.

ARKs are suspended in midwater zones rich in oxygen and water flow, reducing stress and increasing coral survival.

Jumpstarting a reef ecosystem.

ARMs modules carry beneficial microbes and coral fragments to spark healthy reef community growth.

Guided by science and community.

Local stewards, sensors, and divers monitor recovery, tracking coral health, fish return, and ecosystem change.

Why Now

We’re at a tipping point: by 2050, 90% of reefs may be gone without intervention.

Coral Reef ARKs provide a viable path forward combining scientific rigor with community-led action to deliver climate resilience, biodiversity recovery, and blue economy opportunities.

Testimonials

“The Coral ARKs are a perfect fit for reintroducing corals to the Biosphere 2 system to establish a healthy microbiome and grow corals safely and effectively while remediating the degraded substrate.”
Lia Crocker, University of Arizona Biosphere 2
"In addition to their importance as hubs of biodiversity that can bring life back to degraded areas, Coral Reef ARKs are also a game-changer for reef science. These modular, replicable mesocosms provide light, flow, and oxygen conditions that are simply impossible on the degraded seafloor, offering an entirely new platform for understanding and restoring reef ecosystems. When Arks meet probiotics, they become an even more powerful tool to investigate the microbially-driven biogeochemical cycles that make healthy reefs.”
-Dr Raquel Peixoto: Chair of the International Coral Reef Society's Conservation Committee, President of the International Society of Microbial Ecologists, Chair of Marine Science Program KAUST
"The ARKs are a really innovative technology with enough science behind them to make them work, but still simple enough to make them scalable."
-Dr Mark Vermeij, Director of the Caribbean Marine Biology Institute
"The Biosphere 2 Ocean team is thrilled to partner with the Coral ARKs team to further refine and scale these effective platforms for reef restoration. Capitalizing on the 2.6-million-liter ocean mesocosm at the Biosphere 2, we will test optimal Ark designs and environmental conditions for reef growth as we scale-up this proven solution for reef restoration for global impact. Coral Arks serve as an essential tool in the kit of solutions for rebuilding healthy, resilient coral reefs that can maintain critical goods and services for society for decades to come!"
-Diane Thompson, Director of Marine Research at the Biosphere 2
