Santa Barbara Coastal site, station Santa Cruz Island, Diablo, Santa Barbara Channel, study of animal density of Rhacochilus vacca 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 Rhacochilus vacca measurements in numberPerMeterSquared units and were aggregated to a yearly timescale.

EcoTrends项目于2004年由黛布拉·彼得斯博士（约尔达盆地长期生态研究（Long-Term Ecological Research, LTER）站点，美国农业部农业研究服务局约尔达实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究（Long-Term Ecological Research, LTER）站点，美国农业部林业局卢奎洛实验森林）创立，旨在支撑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应用效率。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（ARS）、美国农业部林业局、美国能源部、美国地质调查局（USGS）与众多高校资助的研究站点。EcoTrends项目的数据集可通过探索性网络门户（http://www.ecotrends.info）获取。该门户依托交互式Web应用程序，支持用户持续开展数据汇编与数据访问工作。持续进行的数据汇编工作将通过人工与自动处理两种方式进行更新，这也是长期生态研究站溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分。本网络门户由约尔达LTER与LTER网络办公室联合开发。本次提供的圣巴巴拉海岸（Santa Barbara Coastal, SBC）数据集包含灰背隆头鱼（Rhacochilus vacca）的种群密度数据，单位为numberPerMeterSquared，且已按年尺度进行聚合。
