From mineral to meaning.
Restoration works when technology serves a place, and a place has a voice.
Build a place for coral to come back to.
Mineral Accretion Technology (Biorock®) was invented by the late architect Wolf Hilbertz and Dr. Thomas J. Goreau. It uses safe low-voltage electrical currents in seawater to grow natural crystalline limestone, accelerating coral growth and survival up to 5x even under extreme thermal stress.
“A reef is not a project. It is a relationship.”
We pair field-tested electrochemical engineering with the patience and stewardship of local coastal communities.

Look closer.
Act earlier.
Good restoration begins before the crisis. Our science turns signals in the water into decisions on shore.
HotSpot Bleaching Prediction
A field-facing satellite forecasting method to anticipate thermal stress, share open data, and give coral communities actionable time to respond.
Coral Disease Research
Decades of field documentation, bacteriological analysis, and practical protocols to track and treat emerging marine pathogens.
Ridge to Reef Watershed Resilience
Because what washes down hillsides decides what survives below, holistic soil carbon and watershed management are vital to reef survival.
The reef
remembers.
For decades, our photographers and field teams have maintained an unprecedented visual record of coral ecosystems across the globe — serving researchers, educators, and conservationists.
