Santa Barbara Coastal site, station Carpinteria Reef, Santa Barbara Channel, study of animal density of Embiotoca jacksoni in units of numberPerMeterSquared 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 animal density of Embiotoca jacksoni measurements in numberPerMeterSquared 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站[Jornada Basin LTER]，美国农业部农业研究服务局约拿实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站[Luquillo LTER]，美国农业部林务局卢奎洛实验林）于2004年发起创立，旨在支撑长期生态数据集的采集与分析工作。本项目为一项大型综合研究计划，核心目标在于提升长期生态数据的可访问性与利用效率。目前，已有约50个州级与联邦资助的研究站点参与EcoTrends项目并贡献数据，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 Agricultural Research Service, ARS）、美国农业部林务局、美国能源部、美国地质调查局（United States Geological Survey, USGS）及多所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。该网络门户依托交互式Web应用程序，为用户提供持续的数据整合与数据获取服务。作为长期生态研究网溯源感知综合跟踪架构（LTER Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，其持续开展的数据整合工作通过人工与自动处理两种方式实现更新。该网络门户由约拿盆地LTER与LTER网络办公室联合开发运营。以下来自圣巴巴拉海岸（Santa Barbara Coastal, SBC）的数据集，收录了杰克逊海鲫（Embiotoca jacksoni）的种群密度测量数据，单位为numberPerMeterSquared，且已按年度时间尺度完成聚合。
