MARINe/PISCO: Intertidal: MARINe Long-Term Monitoring Surveys: Photo Plots and Transects Summarized

Long-Term Monitoring and Biodiversity Surveys done by the Multi-Agency Rocky Intertidal Network (MARINe) occur throughout the year at sites ranging from Southeast Alaska to Mexico. Long Term Monitoring surveys assess within-site community change over time, while Biodiversity surveys were designed to capture among-site patterns of community structure (abundance and spatial distribution of species). In combination, the long-term, targeted species approach and the biodiversity surveys provide a wealth of information about the structure and dynamics of rocky intertidal communities along the Pacific Coast of North America.
This metadata record documents the Photo Plot and Transect Survey data for MARINe Long-Term Monitoring surveys. Photo Plots are used to monitor percent cover of organisms within target species assemblages. Plots are established for a given species assemblage if overall cover at a site is sufficient for monitoring. Transects are used to monitor percent cover of surfgrass, kelps, and other algae.
Please note that species of concern have been removed from all public datasets, as well as data from sites funded by the National Park Service (NPS) and the United States Navy. For a comprehensive dataset, please contact the data set owner(s). For more information about the data described in this metadata record, please visit pacificrockyintertidal.org.

多机构岩质潮间带网络（MARINe）开展的长期监测与生物多样性调查全年进行，调查站点覆盖从阿拉斯加东南部至墨西哥的区域。长期监测调查旨在评估站点内群落随时间的变化，而生物多样性调查则用于捕捉站点间群落结构（物种丰度与空间分布）的模式。长期目标物种监测方法与生物多样性调查相结合，为北美太平洋沿岸岩质潮间带群落的结构与动态提供了丰富信息。
本元数据记录记载了MARINe长期监测调查中的照片样地（Photo Plot）与样带调查（Transect Survey）数据。照片样地用于监测目标物种集合内生物的覆盖百分比。若某站点的总覆盖度足以支持监测，则会为特定物种集合设立样地。样带用于监测滨草（surfgrass）、海带及其他藻类的覆盖百分比。
请注意，受关注物种的数据已从所有公开数据集中移除，同时移除的还有由美国国家公园管理局（NPS）及美国海军资助的站点数据。如需完整数据集，请联系数据集所有者。欲了解本元数据记录所述数据的更多信息，请访问pacificrockyintertidal.org。
