Puerto Rico Reef Visual Census (RVC) 2016 - 2021

The National Coral Reef Monitoring Program (NCRMP)’s biological sampling provides a biennial ecological characterization of general reef condition for reef fishes, corals, and benthic habitat (i.e., fish species composition, density, and size; coral species composition, density, size, condition; and benthic community cover) at a broad spatial scale. In the U.S. Atlantic, NCRMP biological sampling includes coral reef and hardbottom habitats in Florida, Flower Garden Banks, Puerto Rico, and the U.S. Virgin Islands (USVI). NCRMP Fish surveys are conducted using the Reef Visual Census (RVC) stationary point count method (Brandt et al. 2009). Fish surveys are conducted at all NCRMP biological survey sites and may occur concurrently with Coral Demographic/Benthic Assessment surveys. These data are fish observations from the RVC in the waters of Puerto Rico in 2016, 2019, and 2021. Data were downloaded from the Southeast Fisheries Science Center (https://grunt.sefsc.noaa.gov/rvc_analysis20/) and standardized to Darwin Core for publication through OBIS-USA. Taxa that could not be aligned to the World Register of Marine Species (WoRMS) were filtered out. Data includes water visibility and fish length measurements.

国家珊瑚礁监测计划（National Coral Reef Monitoring Program，NCRMP）的生物采样工作，可在大空间尺度上对礁区鱼类、珊瑚及底栖生境的整体珊瑚礁状况开展两年一次的生态特征刻画，具体涵盖鱼类物种组成、密度与体型，珊瑚物种组成、密度、体型及健康状态，以及底栖群落覆盖度。在美国大西洋海域，NCRMP生物采样覆盖佛罗里达、花斑珊瑚礁国家海洋保护区（Flower Garden Banks）、波多黎各和美属维尔京群岛（USVI）范围内的珊瑚礁与硬质底栖生境。NCRMP鱼类调查采用礁区视觉普查（Reef Visual Census，RVC）定点计数法（Brandt等，2009），所有NCRMP生物采样点位均会开展此类调查，且可与珊瑚种群统计/底栖评估调查同步进行。本次数据集为2016、2019及2021年波多黎各海域通过RVC方法获取的鱼类观测数据，数据下载自东南渔业科学中心（https://grunt.sefsc.noaa.gov/rvc_analysis20/），并已按照达尔文核心标准（Darwin Core）完成标准化处理，通过OBIS-USA平台发布。无法匹配世界海洋物种登记册（World Register of Marine Species，WoRMS）的分类单元已被过滤移除，数据集包含水体能见度及鱼类体长测量数据。
