Coral Reef Evaluation and Monitoring Project Florida Keys 1997

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, CREMP）旨在对佛罗里达群岛国家海洋保护区（Florida Keys National Marine Sanctuary, FKNMS）内选定珊瑚礁的现状与变化趋势开展监测。该项目自1996年起，每年在固定监测点位开展评估工作，所获数据可用于分析石珊瑚及相关海洋动植物的底栖覆盖度与物种多样性的时间动态变化。核心野外调查方法为水下摄像与计时珊瑚物种清点。本报告呈现的研究数据涵盖1996年至2008年间佛罗里达群岛37个点位的109个监测站位，以及1999年至2008年间德赖托图格斯群岛的采样数据。报告阐述了2007年至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、珊瑚平均物种丰富度，以及石珊瑚异常状况发生情况的年度差异。此外，报告还分析了主要底栖类群、五种珊瑚类群（*Montastraea cavernosa*、*Colpophyllia natans*、*Siderastrea siderea*及*Porites astreoides*）以及穿贝海绵*Cliona delitrix*的长期变化趋势。
