The ʻAuʻau Channel is one of the most protected areas of ocean in the Hawaiian Islands, lying between Lānaʻi and Maui. The channel is also protected by Molokaʻi to the
Evolution of Hawaiian volcanoes Waialeale, and Niihau volcanoes are in this stage of development. Eventually, erosion and subsidence break the volcano down to sea level. At this point, the volcano becomes an atoll, with a ring of coral and sand islands surrounding a lagoon. All the Hawaiian islands west of the Gardner Pinnacles in the Northwestern Hawaiian Islands are in this stage. Atolls are the product of the growth of tropical marine organisms, so these islands are only found in warm tropical waters. Eventually, the Pacific Plate carries the volcanic atoll into waters too cold for these marine organisms to maintain a reef by
