利用光学图像绘制夏威夷群岛珊瑚礁生态系统地图的工作表明，在30-130米深的地方存在着许多石珊瑚和虫藻珊瑚礁，其中大多数以前未被发现。这种珊瑚礁及其相关群落最近被定义为中光珊瑚生态系统。在夏威夷发现了几种类型的MCE，每种MCE都在不同的深度范围内占主导地位，并以珊瑚群落结构和群落形态的独特模式为特征。虽然MCE在群岛的两端附近和之间的许多岛屿上都有记录，但夏威夷MCE的最大深度和流行率随着纬度的增加而下降。夏威夷主要岛屿（MHI）有显着更深，更大的比例的石珊瑚，石珊瑚和大型藻类的覆盖范围内发生的深度箱20米深，比在西北夏威夷群岛（NWHI）的峰值。在整个群岛，随着深度的增加，大型底栖生物类群的生活覆盖的综合百分比急剧下降，随着深度的增加，低于70米，尽管广泛的硬基板。
Efforts to map coral reef ecosystems in the Hawaiian Archipelago using optical imagery have revealed the presence of numerous scleractinian, zoothanthellate coral reefs at depths of 30–130+ m, most of which were previously undiscovered. Such coral reefs and their associated communities have been recently defined as mesophotic coral ecosystems (MCEs). Several types of MCEs are found in Hawai‘i, each of which dominates a different depth range and is characterized by a unique pattern of coral community structure and colony morphology. Although MCEs are documented near both ends of the archipelago and on many of the islands in between, the maximum depth and prevalence of MCEs in Hawai‘i were found to decline with increasing latitude. The Main Hawaiian Islands (MHI) had significantly deeper and greater percentages of scleractinian coral, and peaks in cover of both scleractinian corals and macroalgae occurred within depth bins 20 m deeper than in the Northwestern Hawaiian Islands (NWHI). Across the archipelago, as depth increased the combined percentage of living cover of mega benthic taxa declined sharply with increasing depth below 70 m, despite the widespread availability of hard substrate.
