Our Mission

Our Mission is quite simple, although very difficult to achieve in any one persons lifetime: We aim to protect and preserve the marine biodiversity of the Hawaiian Islands.  Our organization  is comprised of and has partnerships with Federal, State, and local marine biologists, students, and community stakeholders  We operate on the south shore of Oahu, where the reefs hold major biological, economical, and cultural significance. 

If you are interested in joining along and helping protect the reefs of Hawai'i, we have 3 major requirements. Come with a sense of humor, willingness to learn, and a passion for protecting our Biosphere

Maunalua Bay is a bay in the southeast of Honolulu, the capital of Hawaiʻi. The bay extends about 6.3 miles (8.5 kilometers) from the southern tip of Diamond Head, the Black Point, also called Kūpikipikiʻō , in the west to Portlock Point, also known as Kawaihoa Point, to the east.

On the land side, just to the east of Diamond Head is the upmarket suburb of Kāhala. Following are several affluent hillside suburbs like Hawaii Loa Ridge, a gated community that occupies an entire slope. In the east is the suburb of Hawaii Kai, built by industrialist Henry J. Kaiser after World War II. Hawaii Kai has a marina, shopping centers, including a Costco, Walgreens, Longs, and Safeway, and numerous restaurants such as the well-known Roy's and Kona Brewing Co. pub. On the headland leading to Koko Head is the suburb of Portlock, which is a part of Hawaii Kai.

The name Maunalua (from Mauna = mountain and [ʻe]lua = two, in the language of the Polynesian natives) refers to the designation of the area around Hawaii Kai in the period of Polynesian settlement. The mountains, located inland from Portlock Point, are the 645 feet (196 meters) high Koko Head, and about 2.2 miles (3.5 kilometers) east thereof, close to Hanauma Bay the Koko Crater, the walls of which rise up to 1,207 feet (368 meters).

According to legend, Maunalua was one of the first settlements when the first people of Polynesia settled in Hawaiʻi around the 12th century. Native Hawaiians originally lived there by fishing and cultivating sweet potatoes (ʻuala) along the coastal plains at a place called Ke-kula-O Kamauwai. Maunalua was formerly famous for having the largest Native Hawaiian fishpond on Oʻahu. The 523 acre fishpond known as Keahupua-O-Maunalua had a wall or kuapā which originally spanned from Kuliʻouʻou headland and to what is now Portlock. The pond was used primarily to raise mullet (ʻawaʻawa) and was also home to a multitude of endemic or indigenous waterbirds. The area continued to be important for fishing and agriculture until the 1950s when the fishpond was filled for housing development.
