Soft coral counts from photoquadrats and in situ observations collected on St. John, Virgin Islands from 1992-2012 (St. John LTREB project, VI Octocorals project)
收藏资源简介：
<p>Photoquadrats from St. John, USVI, were used to assess the abundance of soft corals from 6 sites on shallow reefs of St. John, USVI from 1992-2012. This retrospective analysis was augmented with in situ surveys in July and August 2013 that were used to quantify the accuracy and precision of the octocoral population census conducted using photoquadrats.</p> <p><strong>Related reference:</strong></p> <p>2015 Lenz EA, Bramanti L, Lasker HR, Edmunds PJ.

<p>本数据集采用采自美属维尔京群岛（United States Virgin Islands, USVI）圣约翰岛的摄影样方（photoquadrat），于1992年至2012年间对该岛浅海珊瑚礁的6个监测点位开展软珊瑚丰度评估。为量化基于摄影样方开展的八放珊瑚（octocoral）种群普查的准确性与精密度，研究团队于2013年7月至8月补充实施原位调查（in situ survey），以此完善本次回顾性分析。</p> <p><strong>相关参考文献：</strong></p> <p>2015 Lenz EA, Bramanti L, Lasker HR, Edmunds PJ. 美属维尔京群岛圣约翰岛八放珊瑚种群的长期变化. 珊瑚礁（Coral Reefs） DOI 10.1007/s00338-015-1315-x</p> <p><strong>相关数据集：</strong><br /> <a href="http://www.bco-dmo.org/dataset/562570" target="_blank">八放珊瑚调查——密度数据</a><br /> <a href="http://www.bco-dmo.org/dataset/562618" target="_blank">八放珊瑚文献综述</a><br /> <a href="http://dmoserv3.whoi.edu/data_docs/St_John_LTREB/octocorals/Lenzetal_CR_MetaDataSTJ2015_BCODMO_2015-07-15.xls">下载提交的Excel数据文件</a></p>
