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（乔纳达盆地长期生态研究站点，美国农业部农业研究服务局（USDA-ARS）乔纳达实验牧场）与阿里尔·卢戈博士（卢基略长期生态研究站点，美国农业部森林服务局（USDA-FS）卢基略实验森林）于2004年创立，旨在支持长期生态数据集的采集与分析工作。该项目是一项大型综合研究计划，核心目标是提升长期生态数据的可获取性与利用效率。目前，已有约50个州政府与联邦资助的研究站点参与并为EcoTrends项目贡献数据，其中包括全部26个长期生态研究（Long-Term Ecological Research，以下简称LTER）站点，以及由美国农业部农业研究服务局（USDA-ARS）、美国农业部森林服务局（USDA-FS）、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项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取，该门户通过交互式网络应用，为用户持续开展数据汇编与数据获取提供支持。作为长期生态研究溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture，以下简称PASTA）的组成部分，持续推进的数据汇编工作通过手动与自动两种处理方式完成更新。该网络门户由乔纳达LTER站点与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，以下简称SBC）的数据集，包含以每平方米为单位的杰克逊海鲫（Embiotoca jacksoni）种群密度测量数据，且已按年度时间尺度进行聚合。
