Discover coral reefs

Hawaiicoral.org is your premier destination to learn all about Hawaiʻi’s 1200 miles of coral reefs and how to help protect them. Our Ko‘a Corps unites citizen scientists like you with local research scientists and government agencies to ensure a holistic approach to reef conservation and action. Please join our inclusive community and help secure a promising future for these vital ecosystems.

Are Coral Reefs Bleaching in your area?

Help our scientists mitigate secondary stress to vulnerable reefs by reporting coral bleaching using our interactive tool.

Here is another shot of Dr. Robin Martin's team conducting an innovative 3D underwater photomapping endeavor across multiple bays around the Big Island. ⁠
⁠
Using structure-from-motion analysis technology, Dr.Martin's group stitches together thousands of photos of corals from different angles to reconstruct the reefs into a composite 3D image. For example, in just one circular 12-meter-diameter plot, up to 10 different species of coral may coexist, with each responding to warming ocean temperatures in a uniquely observable way. By documenting corals before, during, and after bleaching, Dr. Martin and her team will have a record of coral resilience throughout the 2019 marine heatwave event.⁠

Robin Martin, shown here, is a scientist at Arizona State University's Center for Global Discovery and Conservation Science. Dr. Martin is leading an innovative 3D underwater photomapping endeavor across multiple bays around the Big Island. ⁠
⁠
First, Dr. Martin and her team dive down to the seafloor to take thousands of photos. Next, they use structure-from-motion analysis technology, which stitches together thousands of photos of corals from different angles to reconstruct the reefs into a composite 3D image.⁠

In this photo, Greg Asner, director of ASU's Center for Global Discovery and Conservation Science, is shown investigating the impact of the current Pacific ocean heatwave on Hawaii's coral reefs. In the next few months, Asner's team hopes to find and identify heat resistant coral species in regions of Hawaii that have experienced the worst coral bleaching. Heat resistant species could potentially be used in future coral reef restoration efforts. ⁠
