Coral Reef Evaluation and Monitoring Project Dry Tortugas 2000

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. It is one of the longest running coral reef monitoring projects in south Florida and has been extremely important in documenting the temporal changes that have occurred in recent years.

珊瑚礁评估与监测项目（Coral Reef Evaluation and Monitoring Project，简称CREMP）旨在监测佛罗里达群岛国家海洋保护区（Florida Keys National Marine Sanctuary，简称FKNMS）内选定珊瑚礁的现状及趋势。自1996年起，CREMP评估每年在固定地点进行，所收集的数据提供了关于底栖覆盖度和石珊瑚及其相关海洋植物和动物多样性的时间变化信息。核心野外方法持续为水下摄影和珊瑚物种计时清点。本报告呈现的研究成果包括1996年至2008年在佛罗里达群岛的109个站点和37个地点，以及1999年至2008年在干岩礁（Dry Tortugas）的样本数据。报告描述了2007年至2008年年度差异（主要底栖类群百分比覆盖度，包括石珊瑚、八放珊瑚、海绵和大型藻类）、平均珊瑚物种丰富度和石珊瑚状况发生率的差异。此外，它还考察了主要底栖类群、五个珊瑚复合体（Montastraea cavernosa、Colpophyllia natans、Siderastrea siderea、Porites astreoides）以及珊瑚藻（Cliona delitrix）的长期趋势。该项目是南佛罗里达最长久的珊瑚礁监测项目之一，对于记录近年来发生的时序变化具有重要意义。
