Monitoring Coral Reefs in Kaneohe Bay

At Captain Bruce, we are committed to raising awareness about the ocean and climate change through various initiatives. 

Following our participation in the beach clean-up event held on Earth Day in April, Captain Bruce partnered with the Hawaii non-profit organization “Aloha Ocean Plus” to conduct our third coral reef monitoring in Kaneohe Bay.

The Importance of Monitoring

To understand the health of coral reefs, it is important to record and analyze the color of corals and other factors over a long period of time. According to Yui, the representative of Aloha Ocean Plus, the color of corals varies depending on the species and environment, so we monitor the changes in their condition over a year or more.

Core Cards

During monitoring, we record the color of corals using a color chart called a “core card” developed based on the color of Hawaiian corals. The color of corals varies depending on the species, but even the same species does not have the same color. White indicates bleaching, but for other colors, it does not mean that the condition is bad because it is number so-and-so on the core card. The color changes are recorded and used for research through continuous monitoring. Aloha Ocean Plus shares about 20 photo data taken during monitoring with a specialized institution each time.

To Protect the Beautiful Hawaiian Sea

The monitoring conducted this time confirmed that there is no coral bleaching occurring at Captain Bruce’s snorkeling spots. We aim to protect the environment and maintain this state so that tourists, locals, and all of us who work here can continue to enjoy the beautiful sandbar together.

As a company that conducts tours in the beautiful Hawaiian sea, we recognize the importance of responsible tourism and will continue to promote various initiatives in the future.
