Santa Barbara Coastal site, station Santa Cruz Island, Twin Harbor West, Santa Barbara Channel, study of cover of algae in units of percent on a yearly timescale

The EcoTrends project was established in 2004 by Dr. Debra Peters (Jornada Basin LTER, USDA-ARS Jornada Experimental Range) and Dr. Ariel Lugo (Luquillo LTER, USDA-FS Luquillo Experimental Forest) to support the collection and analysis of long-term ecological datasets. The project is a large synthesis effort focused on improving the accessibility and use of long-term data. At present, there are ~50 state and federally funded research sites that are participating and contributing to the EcoTrends project, including all 26 Long-Term Ecological Research (LTER) sites and sites funded by the USDA Agriculture Research Service (ARS), USDA Forest Service, US Department of Energy, US Geological Survey (USGS) and numerous universities. Data from the EcoTrends project are available through an exploratory web portal (http://www.ecotrends.info). This web portal enables the continuation of data compilation and accessibility by users through an interactive web application. Ongoing data compilation is updated through both manual and automatic processing as part of the LTER Provenance Aware Synthesis Tracking Architecture (PASTA). The web portal is a collaboration between the Jornada LTER and the LTER Network Office. The following dataset from Santa Barbara Coastal (SBC) contains cover of algae measurements in percent units and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（约拿盆地长期生态研究网（Long-Term Ecological Research, LTER），美国农业部农业研究服务局（United States Department of Agriculture Agricultural Research Service, USDA-ARS）约拿实验牧场）与阿里尔·卢戈博士（卢奎略长期生态研究网（LTER），美国农业部林业局（United States Department of Agriculture Forest Service, USDA-FS）卢奎略实验林）于2004年创立，旨在支持长期生态数据集的采集与分析工作。本项目属于大型综合研究计划，核心目标是提升长期生态数据的可获取性与复用价值。目前共有约50个州级与联邦资助的研究站点参与并贡献数据至EcoTrends项目，其中涵盖全部26个长期生态研究（Long-Term Ecological Research, LTER）站点，以及由美国农业部农业研究服务局（USDA-ARS）、美国农业部林业局（USDA-FS）、美国能源部（United States Department of Energy, DOE）、美国地质调查局（United States Geological Survey, USGS）及众多高校资助的研究站点。EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取。该门户搭载交互式网页应用程序，支持用户持续开展数据汇编与数据获取工作。作为长期生态研究网溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，持续推进的数据汇编工作通过人工与自动结合的处理流程完成更新。该网络门户由约拿盆地LTER站点与LTER网络办公室联合打造。下述来自圣巴巴拉海岸（Santa Barbara Coastal, SBC）的数据集包含以百分比为单位的藻类盖度测量数据，且已按年度时间尺度进行聚合汇总。
