Coral Reef Evaluation and Monitoring Project Florida Keys 2010

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）的宗旨为监测佛罗里达群岛国家海洋保护区（Florida Keys National Marine Sanctuary，缩写FKNMS）内选定珊瑚礁的现状与变化趋势。自1996年起，项目组已在固定监测点位持续开展年度CREMP评估，所采集的数据可用于揭示石珊瑚（stony corals）及相关海洋动植物的底栖覆盖度（benthic cover）与物种多样性的时间动态变化。核心野外监测方法始终为水下摄像技术与定时珊瑚物种名录调查。本报告呈现的监测结果涵盖1996至2008年间佛罗里达群岛37个点位的109个采样站数据，以及1999至2008年间德赖托图格斯群岛（Dry Tortugas）的相关采样数据。本报告详述了2007至2008年间主要底栖类群（benthic taxa）——石珊瑚、八放珊瑚（octocorals）、海绵（sponges）与大型藻类（macroalgae）——的覆盖占比、珊瑚物种平均丰富度以及石珊瑚病害发生情况的年度差异。此外，报告还分析了主要底栖类群、五种珊瑚复合体（大星珊瑚*Montastraea cavernosa*、脑纹珊瑚*Colpophyllia natans*、平坦星孔珊瑚*Siderastrea siderea*、团块滨珊瑚*Porites astreoides*）以及穿贝海绵（clionaid sponge）物种*Cliona delitrix*的长期变化趋势。
