finding Refuge for Corals

In 2019, a marine heatwave across the Hawaiian Islands caused ocean temperatures to rise and corals to bleach. When corals bleach, they are more vulnerable to other stressors. These stressors may lead to the corals death. Some reefs, due to environmental factors or the type of coral species, persist in the face of marine heatwaves and coral bleaching.

Check out how Hawai‘i’s reefs have changed after the 2019 bleaching event.

Did you know that many of Hawaii’s iconic surf breaks are created by coral reefs? Coral reefs create the classic barrel that Native Hawaiians have enjoyed surfing for centuries.

Did you know that the health of Hawaii’s forests is important to the health of Hawaii's coral reefs? According to the Department of Land and Natural Resources, Without a healthy forest to anchor soil and temper the erosive effects of heavy rainfall, sediment can wash off the mountains and enter ocean ecosystems. Sediment increases stress on the corals, making them more prone to mortality. 

Although they may seem far apart, Hawaii’s different ecosystems exist in a tightly connected system that relies on the health of all parts. When we work to protect one, we work to protect all.

Did you know that juvenile coral are the foundation of coral reefs? Juvenile coral’s ability to settle and establish new coral reef is essential to the health of our marine ecosystem. @Asnerlab graduate student , Rachel Carlson, is currently analyzing 320 limestone tiles that she placed throughout South Kona’s reefs. Comparing the coral growth from different locations will give us a better understanding of what promotes young coral’s settling ability.
