A new approach allows for mapping Rapid Ohia Death in Hawaii’s last remaining native forests.
A spectral basis for detection, mapping, and monitoring the spread of Rapid Ohia Death in Hawaiian forests.
The CAO Coral Reef Challenge
Gregory P. Asner, September 2017
Coral reefs are global hotspots of biological diversity and support the livelihoods of more than a billion people worldwide. Coral reefs cover roughly 500,000 km2 of the Earth’s surface, but are sparsely distributed over more than 200 million km2 of ocean (Figure 1). Field studies currently represent less than 0.01% of coral reefs worldwide, and although local monitoring is important, it provides little understanding of the trajectory of coral reefs undergoing regional and global environmental change.

KONA, Hawaii — Hawaiian lawmakers are considering a ban on some popular sunscreens to try to protect coral reefs.
Researchers found that oxybenzone, a UV filtering ingredient commonly found in lotions, harms the coral. Up to 14,000 tons of sunscreen wind up in coral reef areas of the ocean every year, and scientists say that contributes to the ecosystem’s damage.
The Big Island of Hawaii’s pristine coastline is home to one of the state’s largest coral reefs, a miles-long stretch that scientists say is dying at an alarming rate.
A century of declining rainfall is closely tied to observed changes in forest structure and photosynthesis in Hawaii.
