Pacific Reef Assessment and Monitoring Program: Belt Transect for Demographics and Condition of Corals at U.S. Pacific Reefs from 2008-09-14 to 2012-05-19 (NCEI Accession 0163749)

The data described here result from benthic coral demographic surveys in the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas as part of NOAA's Pacific Reef Assessment and Monitoring Program (Pacific RAMP). Adult colony surveys record morphology, colony size, partial mortality in two categories - old dead and recent dead, cause of recent dead partial mortality, and non-lesion forming condition including bleaching and disease. The survey domain encompassed the majority of the mapped area of reef and hard bottom habitats in the 0-30 m depth range. Sites were surveyed using belt transects to collect adult coral colony metrics. These data provide information on adult coral abundance (density, proportion occurrence, and total colony abundance), size distribution, partial mortality, prevalence and abundance of recent mortality and cause, prevalence of disease and bleaching, and diversity.本数据集源自美国国家海洋和大气管理局（National Oceanic and Atmospheric Administration, NOAA）太平洋珊瑚礁评估与监测计划（Pacific Reef Assessment and Monitoring Program, 简称Pacific RAMP）在夏威夷群岛、马里亚纳群岛、美属萨摩亚及太平洋偏远岛群开展的底栖珊瑚种群生态学调查。成体珊瑚群落调查记录了珊瑚形态特征、群落规模、两类部分死亡类别——旧死亡与近期死亡、近期死亡的诱因，以及非病灶形成类异常状况（涵盖珊瑚白化与珊瑚病害）。 本次调查覆盖0至30米水深范围内绝大多数已测绘的珊瑚礁与硬质底栖生境区域。各调查站点采用带状样带法（belt transects）采集成体珊瑚群落的相关指标数据。本数据集涵盖成体珊瑚丰度（包括密度、出现占比及总群落丰度）、规模分布、部分死亡情况、近期死亡的流行率与丰度及其诱因、珊瑚疾病与白化的流行率，以及物种多样性等相关信息。
