Coral Reef Evaluation and Monitoring Project Dry Tortugas 2014

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 collectedprovides information on the temporal changes in benthic cover and diversity of stony corals andassociated marine flora and fauna. The core field methods continue to be underwatervideography and timed coral species inventories. Findings presented in this report include datafrom 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）旨在监控佛罗里达群岛国家海洋保护区（Florida Keys National Marine Sanctuary，简称FKNMS）中选定珊瑚礁的现状及变化趋势。自1996年起，CREMP评估工作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随时间变化的详细信息。核心实地调查方法包括水下摄影和珊瑚物种定时清点。本报告呈现了1996年至2008年在佛罗里达群岛和1999年至2008年在干燥礁（Dry Tortugas）的109个站点、37个地点的数据。报告描述了2007年至2008年之间主要底栖类群（石珊瑚、八放珊瑚、海绵和大型藻类）覆盖率、平均珊瑚物种丰富度和石珊瑚状况发生率的年度差异。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Cliona delitrix石海绵的长期趋势。该项目是南佛罗里达持续时间最长的珊瑚礁监测项目之一，对于记录近年来发生的时空变化具有重要意义。
