Santa Barbara Coastal site, station Naples Reef, Santa Barbara Channel, study of animal density of Sebastes serriceps 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 Sebastes serriceps 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（约拿盆地长期生态研究站点（Long-Term Ecological Research，简称LTER），美国农业部农业研究服务局（USDA-ARS）约拿实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站点（LTER），美国农业部林业局（USDA-FS）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。该项目为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率。目前共有约50个由州级及联邦政府资助的研究站点参与并向EcoTrends项目贡献数据，其中涵盖全部26个LTER站点，以及由USDA-ARS、美国农业部林业局、美国能源部、美国地质调查局（USGS）及众多高校资助的站点。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获取操作。作为LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture，简称PASTA）的组成部分，持续推进的数据汇编工作通过人工与自动两种处理方式完成更新。该网络门户由约拿LTER站点与LTER网络办公室合作开发。本次来自圣巴巴拉海岸（Santa Barbara Coastal，简称SBC）的数据集包含以每平方米数量（numberPerMeterSquared）为单位的平鲉（Sebastes serriceps）种群密度测量数据，且已按年度时间尺度完成聚合。
