Coral Reef Evaluation and Monitoring Project Florida Keys 2016

The purpose of the Coral Reef Evaluation and Monitoring Project (CREMP) is to monitor the status and trends of selected reefs in the Florida Keys National Marine Sanctuary(FKNMS). CREMP assessments have been conducted annually at fixed sites since 1996 and data collected provides information on the temporal changes in benthic cover and diversity of stony corals and associated marine flora and fauna. The core field methods continue to be underwater videography and timed coral species inventories. Findings presented in this report include data from 109 stations at 37 sites sampled from 1996 through 2008 in the Florida Keys and 1999 through 2008 in the Dry Tortugas. The report describes the annual differences (between 2007 and 2008) in the percent cover of major benthic taxa (stony corals, octocorals, sponges, and macroalgae), mean coral species richness and the incidence of stony coral conditions. Additionally, it examines the long-term trends of the major benthic taxa, five coral complex, Montastraea cavernosa, Colpophyllia natans, Siderastrea siderea, and Porites astreoides) and the clionaid sponge, Cliona delitrix.

珊瑚礁评估与监测项目（Coral Reef Evaluation and Monitoring Project，缩写CREMP）旨在监测佛罗里达群岛国家海洋保护区（Florida Keys National Marine Sanctuary，缩写FKNMS）内选定礁区的现状与变化趋势。自1996年起，该项目便在固定监测点开展年度评估，所采集的数据可反映石珊瑚及相关海洋动植物的底栖覆盖度与多样性的时序变化。项目核心野外调查方法沿用水下摄像与计时珊瑚物种调查。本报告呈现的调查结果涵盖1996至2008年佛罗里达群岛的37个监测点、共109个站位，以及1999至2008年德赖托图格斯群岛的相关监测数据。报告详述了2007至2008年间主要底栖类群（石珊瑚、八放珊瑚、海绵与大型藻类）的覆盖百分比差异、珊瑚物种平均丰富度，以及石珊瑚健康状况的发生情况。此外，报告还分析了主要底栖类群、五种珊瑚复合体（含洞穴杯珊瑚（Montastraea cavernosa）、脑纹珊瑚（Colpophyllia natans）、星孔珊瑚（Siderastrea siderea）与团块微孔珊瑚（Porites astreoides）），以及蚀穴穿贝海绵（Cliona delitrix）的长期变化趋势。
