Georgia Coastal Ecosystems site, station High Marsh site, study of plant biomass of Spartina alterniflora in units of gramsPerSquareMeter 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 Georgia Coastal Ecosystems (GCE)
contains plant biomass of Spartina alterniflora measurements in gramsPerSquareMeter units
and were aggregated to a yearly timescale.

EcoTrends项目由黛布拉·彼得斯博士（若纳盆地长期生态研究站，美国农业部农业研究服务局若纳实验牧场）与阿里尔·卢戈博士（卢奎洛长期生态研究站，美国农业部林务局卢奎洛实验林）于2004年创立，旨在支持长期生态数据集的采集与分析工作。
本项目为大型综合研究计划，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个州级及联邦资助的研究站点参与EcoTrends项目并贡献数据，其中包括全部26个长期生态研究站点（Long-Term Ecological Research, LTER），以及美国农业部农业研究服务局（USDA Agriculture Research Service, ARS）、美国农业部林务局（USDA Forest Service）、美国能源部（US Department of Energy）、美国地质调查局（US Geological Survey, USGS）资助的站点与众多高等院校。
EcoTrends项目的数据可通过探索性网络门户（http://www.ecotrends.info）获取。该门户依托交互式网络应用程序，为用户提供持续的数据汇编与数据获取服务。作为LTER溯源感知综合跟踪架构（Provenance Aware Synthesis Tracking Architecture, PASTA）的组成部分，其持续的数据汇编工作通过手动与自动两种处理方式进行更新。
本网络门户由若纳LTER站与LTER网络办公室合作开发。
