Advancing deep reef science through exploration, data-driven research, and collaboration that drives lasting impact.

How We Make an Impact

Hawaiʻi’s deep reefs—known as mesophotic coral ecosystems (30–100 m)—are among the most extensive yet least explored marine habitats in the islands.


These deeper ecosystems also harbor extraordinary biodiversity.

43–46%

Endemic fish species at mesophotic depths

By using advanced mapping, diving, and monitoring technologies, we bring these hidden ecosystems into view.


The knowledge we generate allows us to:

Empower communities with science that connects cultural practices and reef health.

Support conservation policies that span the full depth range of coral reefs.

Advocate for protection of mesophotic habitats rarely considered in marine planning.

Highlight biodiversity value that strengthens local and global arguments for reef protection.

Through this work, we transform unseen ecosystems into powerful evidence for action—ensuring that Hawaiʻi’s deep reefs are recognized and safeguarded as vital parts of the archipelago’s natural heritage.
