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（Multi-Agency Rocky Intertidal Network, MARINe）开展的长期监测与生物多样性调查全年覆盖从阿拉斯加东南部至墨西哥的各类监测点位。其中，长期监测调查用于评估单点位内群落随时间的动态变化，而生物多样性调查则旨在刻画不同点位间的群落结构模式，即物种丰度与空间分布特征。二者协同应用，即长期靶向物种研究方案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详实的研究数据。

本元数据记录记载了MARINe长期监测调查中的样方照片（Photo Plot）与样带调查（Transect Survey）数据集。样方照片用于监测目标物种组合（species assemblages）内的生物盖度百分比，仅当点位整体生物盖度满足监测要求时，才会针对特定物种组合设立对应样方。样带调查则用于监测海草（surfgrass）、大型褐藻（kelps）及其他藻类的盖度百分比。

请注意，所有公开数据集均已移除受关注物种的相关数据，同时也剔除了由美国国家公园管理局（National Park Service, NPS）与美国海军资助的监测点位的全部数据。如需获取完整数据集，请联系数据集所有者。若需了解本元数据记录中描述的数据集更多详情，请访问pacificrockyintertidal.org。
